Important recommendations and warnings

The following recommendations and warnings should be taken into account when using Fortimo LED LLM Gen 3 modules and Xitanium drivers.

Design-in phase • It is mandatory to use the approved Philips Xitanium LED drivers. For a list of

approved drivers please see Tables 2 and 3.• It is mandatory to design the luminaire enclosed in such a way that it can only

be opened with special tools (by an electrician) in order to prevent accidentalcontact with live parts (Fortimo LED LLM Gen 3 module with a voltage potentialof 93 V DC).

• Safety and IEC recommendations: the general IEC recommendations for luminairedesign and national safety regulations (ENEC, CE, etc.) also apply to selectedFortimo LED LLM Gen 3 modules and drivers. Luminaire manufacturers are advisedto conform to the international standards for luminaire design (IEC 60598 -Luminaires).

• Do not apply mains power directly to the LED module.• When using Xitanium Programmable LED drivers, the MTP and CLO profiles

need to be activated and programmed.

Design-in and manufacturing phase • Do not use damaged or defective modules.• Do not drop the LED module or let any object fall on it as this may damage themodule. Do not use the LED module if it has been dropped or an object has fallenon it and there are visible defects or damage.

Installation and service phase of luminaires• The luminaire should not be serviced while the mains voltage is connected; this

includes connecting or disconnecting the Fortimo LED LLM Gen 3 cable.• Hot switching is not allowed.


Mechanical characteristics

Fortimo LED LLM Gen 3 module The module consists of the following components: • PCB with LEDs • PCB reflector • Mixing chamber (housing) • Heat spreader • Diffuser High-quality, efficient white light is achieved with a PCB with high-power white LEDs and diffuser plates. The mixing chamber ensures perfectly mixed light, resulting in uniform color and good color consistency. The function of the diffuser is to shape the light beam, resulting in a batwing distribution. This enables freedom of design in the secondary optics and/or reflector. The base of the module acts as a heat spreader and facilitates optimal heat transfer. This makes it easier for luminaire manufacturers to design their own thermal solutions. The heat spreader has holes on either side for fixation (D1 in Figure 7).

Lighting characteristics

Figure 18. Fortimo LED LLM Gen 3 polar diagram

Light distribution The Fortimo LED LLM Gen 3 provides batwing light distribution, making it suitable for a variety of applications such as street lighting and urban lighting. Optical files Optical files can be downloaded in the following formats: CIB, IES, LDT, PHL, including a file with Ray-sets, from the Fortimo LED LLM website. Photometric files such as CIB, IES, LDT and PHL can be used to check the Fortimo LED LLM Gen 3's far-field intensity distribution. The final design could be verified using a simulation performed with a Ray-set for the Fortimo LED LLM Gen 3. Fortimo LED LLM Gen 3 modules are optically backwards compatible with Gen 2 reflector designs.

Spectral light distribution

Figure 19. Spectral light distribution for the Fortimo LED LLM Gen 3 3000 K and 4000 K Color consistency (SDCM)

The color consistency of the Fortimo LED LLM Gen 3 is specified to <7 SDCM over the product’s lifetime. Typical color consistency is specified to <5 SDCM. SDCM stands for Standard Deviation of Color Matching and the value 5 refers to the size of an ellipse around the specified target point.

Figure 20. Color consistency



Figure 20, on the previous page, shows color targets for the different color temperatures of the Fortimo LED LLM Gen 3. These are specified in the operating conditions Tcase = 65 °C, Tambient = 25 °C.

Optical design (secondary optics)

The Fortimo LED LLM module generates a batwing beam shape, which is a pragmatic starting point for secondary optics design by OEMs. Secondary optics are not part of the Fortimo LED LLM system offering as this is a value-add area for OEMs. For support in reflector designs please check the list of complementary partners (see chapter ‘Contact details’).

Starting characteristics

After ignition or re-ignition of the driver the module will immediately produce the intended amount of light.

Lifetime characteristics

The Fortimo LED LLM Gen 3 has an expected lifetime of 50,000 burning hours with 90% survivals. When used with Xitanium LED drivers with enabled CLO feature, the system delivers 100% lumen maintenance. All dedicated system drivers are pre-programmed with CLO.

Specified lifetime performance Figure 21 below shows the expected lumen maintenance during a typical product

lifetime when Fortimo LED LLM modules are used without the CLO feature.

Figure 21. Fortimo LED LLM Gen 3 lumen maintenance without CLO, Tcase = 65 °C


Thermal management

The critical thermal management points for the module and driver are set out in this chapter in order to facilitate the design-in of the Fortimo LED LLM Gen 3 system. Keeping these thermal points in mind will help to ensure the optimal performance and lifetime of the system.

Operating temperatures Definitions

• Module temperature: temperature measured at the specified Tcase point (at the bottom) of the module

• Driver temperature: temperature measured at the specified Tcase point of the driver

• Ambient temperature: temperature of the air surrounding the luminaire in the test environment or application

• Ambient temperature in lab environment: air temperature in a testing area, in a controlled environment free from drafts

• Average ambient temperature: monthly average temperature based on at least 2 measurements daily, with minimum 8-hour intervals between measurements

Differences between LLM Gen 3 and LLM Gen 2

Figure 22. Fortimo LED LLM Gen 2 module

Figure 23. Fortimo LED LLM Gen 3 module

Fortimo LED LLM Gen 3 differs from the previous Fortimo LED LLM Gen 2 in several aspects which have an influence on thermal management. The Fortimo LED LLM Gen 3 has switched to efficient, high-power white LEDs, making the use of remote phosphor obsolete. Although overall system efficiency has increased, the thermal power is now concentrated at the LEDs. In the previous generation the thermal power was distributed between the LEDs and the remote phosphor. The switch to white LEDs removed the limitation of the ambient temperature inside the luminaire, which was necessary to safeguard the performance of the remote phosphor. Now the only critical temperatures that need to be measured during design-in are: • ambient temperature around the luminaire • Tcase temperature at the bottom of the module

To ensure backwards thermal compatibility with existing Gen 2 heatsinks and fixtures, the Tcase temperature limit has been raised by 10 °C, to 65 °C. For the full thermal specifications and temperature limits of the individual Fortimo LED LLM Gen 3 modules, please refer to Appendix A.


Module temperature

To achieve typical product lifetime characteristics, it is critical to ensure that the product is operating within specified temperature limits. These limits depend on both the product and the application, including luminaire design and ambient environment.

Warning! • Maximum Tcase should never exceed Tcase max. • When the module exceeds Tcase max, the system driver will

automatically dim the module • Thermal design should ensure that Tcase <65 °C (beginning of

life, with respect to CLO) • Thermal design must ensure maximum ΔT (Tcase – Tamb) ≤40 °C

To define the correct temperature limit and validate thermal luminaire design, the maximum ambient temperature at which the luminaire will operate constitutes the initial key criteria. Scenario 1 If the maximum ambient temperature (Tamb,max) is 25 °C or lower, the luminaire design needs to ensure that the module temperature does not exceed 65 °C when tested in a lab environment at 25 °C ambient. Scenario 2 When Tamb,max exceeds 25 °C during module operating hours, the maximum Tcase specified is 65 °C, tested in a lab environment at Tamb,max. Note: The ambient temperatures referred to above indicate average temperatures during the operational period of the module. In terms of temperature, the critical components inside the module are: • Solder joints of the components • Junction of the LEDs

Thermal measurements Critical temperature point (Tcase)

For LEDs, the junction temperature is the critical factor for operation. Since there is a direct relation between the case temperature and the LED junction temperature, it is sufficient to measure the aluminum casing of the Fortimo LED LLM module at its critical temperature point. If the case temperature at the Tcase point exceeds the recommended Tcase life of 65 °C, the performance of the LEDs and the Fortimo LED LLM system will be adversely affected in terms of light output, lifetime and lumen maintenance.


Measurement of critical temperature point The Tcase should be measured at its critical temperature point with a thermocouple on the bottom of the module, inside the left or right groove at the center point location (Figure 24).

Figure 24. Temperature test point on bottom of the module Note:

In order to ensure accurate Tcase test results, the case temperature should not vary by more than 1 °C for a period of at least 30 minutes.

Critical module temperature point with respect to CLO

The Fortimo LED LLM Gen 3 system with dedicated Fortimo drivers offers the pre-programmed Constant Light Output (CLO) feature. Over system lifetime the driver will automatically increase output current to the LED module in order to compensate for lumen depreciation and keep light output constant. For a thermal design developed to ensure the Tcase point ≤65 °C at the beginning of life, this means that over lifetime the Tcase will rise above 65 °C, which is expected. This effect has been taken into account in the system lifetime predictions.

Thermal derating

Thermal derating with dedicated system drivers The Fortimo LED LLM Gen 3 system is equipped with a thermal de-rating system to prevent extreme lifetime degradation of the module when it is operated at temperatures exceeding its maximum specification, e.g. during peaks in ambient temperature around the luminaire or in case of underperformance of the heat management system. The thermal de-rating system is a default setting in the dedicated Fortimo LED LLM system drivers. When the case temperature rises above the specified limit, typically 75 °C, a thermal circuit will be engaged, reducing output current to the module. Depending on the module temperature, the current will be between 100 % and the minimum dim level. Due to the component spread in the LED LLM module and driver, the dim trigger point will typically fall somewhere between 75 - 80 °C. The trigger point is also dependent on the thermal design of the luminaire. This variance will also apply to the module shut-off point. Note: The thermal circuit is used in all Fortimo LED LLM modules.


Thermal derating with Xitanium Programmable LED drivers When using Fortimo LED LLM Gen 3 modules in combination with Xitanium

LED Programmable drivers, it is necessary to activate and program the correct Module Temperature Protection (MTP) settings. To simplify programming, the Fortimo LED LLM Gen 3 profiles for both Xitanium Prog and Prog+ LED drivers is available on request from your Philips sales representative

Warning! The thermal circuit is only a failsafe in order to protect the module against overheating during peaks in ambient temperatures or in case of faulty heatsink design. The optimum performance is only achieved if the Tcase stays below 65 °C at the specified maximum ambient, measured according to the procedure described above.

Heatsink design

Figure 25. Three types of heat transport

The heat produced by the Fortimo LED LLM driver and module in the luminaire (or similar housing) must be dissipated to the surroundings. If this is not taken care of it will have an adverse effect on system performance and lifetime. For thermal specifications of individual modules, please refer to Appendix A. To ensure optimum performance, it is essential that the critical temperature of the module stays below 65 °C. The thermal management can be done in three ways: convection, conduction and radiation or a combination of these. Note: The objective of this chapter is not to indicate exactly how to calculate a heatsink, but to give some guidelines on how to improve its performance.

Two thermal design concepts are shown for passive cooling of the Fortimo LED

module: • Concept A: regular heatsink design • Concept B: luminaire as part of heatsink

Figure 26. Concept A: regular heatsink design

Figure 27. Concept B: luminaire as part of heatsink

To simplify thermal management, the heatsink can be designed in such a way that it becomes one with the luminaire housing. By making the housing of the luminaire an integral part of heat management, it is possible to reduce the surface area of the internal heatsink, possibly also reducing the size of the luminaire. The main objective is to extract the heat from the module and dissipate it into the


ambient air. The two simplified thermal network models are depicted in Figures 26 and 27.

Heatsink material The type of material used has a large influence on the final result. For example,

a comparison of the thermal conductivity (k) of copper with that of corrosion-resistant steel (see Table 8) shows that a substantially smaller heatsink can be made with copper. The best material for heatsinks is (soft) aluminum. The thickness (H) of the heatsink is also of major importance. Assuming that identical heatsinks made with from different material are used, a similar effect would be achieved with 1 mm copper, 2 mm aluminum, 4 mm brass, 8 mm steel or 26 mm corrosion-resistant steel.

Thermal radiation and emissivity coefficient

Thermal radiation forms a substantial part of the total heat transfer. The amount of thermal radiation is highly dependent on the emissivity coefficient of the surface. For example, a polished aluminum surface has a very low emissivity coefficient, while a painted surface has a very high one. A higher emissivity coefficient means better transfer of heat.

Thermal interface

Figure 29. Interface between module and mounting plate filled with thermal paste

The thermal interface is the interface between the module and the mounting surface in the luminaire. To ensure good thermal contact, it is recommended that the contact area be covered with thermal interface material, e.g. thermal paste (see Figure 29). If the use of thermal paste is not appropriate, and some other thermal interface material is used (e.g. phase change or thermal pad) it is strongly recommended that the installation instructions for the selected interface materials be followed.

Warning! The use of thermal interface materials other than thermal paste might require a larger heatsink.


Xitanium LED driver temperature

Figure 30. Labels on the Xitanium drivers indicates Tcase point

The next key component is the driver, which influences the lifetime and reliability of the system. It is important to ensure good contact between the driver and the luminaire as this enables the heat to dissipate efficiently. The driver temperature can be measured with a thermocouple at the Tcase point, shown on the driver label (Figure 30). Critical driver temperature point with respect to CLO Over lifetime the dedicated Fortimo LED LLM system drivers with CLO will increase their power output. As a result, the driver losses will increase accordingly, which in turn will lead to higher Tcase temperatures. This temperature effect is expected and has been taken into account in the lifetime predictions of the Fortimo LED LLM system. For the thermal design it is sufficient to ensure that the Tcase temperature of the driver is within specification for Tcase life at the beginning of life. For the thermal specifications of the dedicated Fortimo LED LLM system drivers please refer to Appendix A. For Xitanium Programmable LED drivers, please refer to individual product datasheets for Tcase life information.


Important points for luminaire design • Ensure good thermal contact between the module/driver and the coldest

part of the luminaire • Place the module(s) and driver at a distance from each other to obtain a

more homogeneous temperature distribution in the luminaire • When mounting modules directly on the luminaire housing, we recommend

using aluminum that is at least 3 mm thick; thinner material will limit the heat flow through the luminaire housing. Thicker material will improve the heat flow through the luminaire housing, resulting in a lower Tcase of the module

• Use anodized, painted surfaces rather than blank surfaces in order to increase the transfer of heat via thermal radiation

• In order to accommodate every application, Fortimo LED LLM Gen 3 modules can be dimmed or used in pairs to optimize the lumen package

• Use highly thermally conductive materials (e.g. aluminum) in the primary heat path

• Limit the number of thermal interfaces in the primary heat path towards the ambient air

Compatibility with Fortimo LED LLM Gen 2 thermal solutions Fortimo LED LLM Gen 3 modules are thermally backwards compatible with

Fortimo LED LLM Gen2 for all CCT and lumen packages with no thermal risk. The compatibility is for identical lumen and CCT combinations. In some cases, a Gen 3 module with a different lumen or CCT package may be used with a Gen 2 heatsink (e.g. a Gen 3 1800lm/740 module on a heatsink for a Gen 2 1100lm/730 module). The possible upgrade depends on operating conditions. You are strongly advised to request Philips design-in support if an upgrade is intended. Note: Design-in support is available; please contact your Philips sales representative.


Controllability

Default dimming protocols Dedicated LLM system drivers offer integrated light control options. • All dedicated drivers offer a pre-programmed Constant Light Output (CLO)

feature, resulting in 100% lumen maintenance at 50,000 hours. • CLO must be programmed in the Xitanium 150W 1.05A Prog+ GL-F sXt

driver for 6000lm system Fortimo LED LLM 1100 and 1800 lm dimming options: • Fixed output (no dimming) • LumiStep 6-hr (0/6) dimming • LumiStep 8-hr (2/6) dimming Fortimo LED LLM 3000 and 4500 lm dimming options: • 1-10 V dimming

Fortimo LED LLM 6000 lm dimming options: • Constant Light Output (must be programmed) • 1-10 V, AmpDim, DALI and Dynadimmer dimming

Figure 31. LumiStep dimming

Warning! While it is technically feasible to dim Fortimo LED LLM Gen 3 modules down to 10% of specified lumen package, Philips makes no statements on product performance for modules operating on an output current below 100 mA.

Please refer to the performance tables in Appendix A for individual module current settings. LumiStep LumiStep is a stand-alone dimming protocol which dims the light level for a pre-determined period (6 or 8 hours) every night: see Figure 31. The intelligent software which controls the LumiStep protocol counts the time between the switch-on and switch-off points for three days in a row, and determines the middle point based on these inputs. The mid-point determines when dimming should start and stop. As most lighting installations use sunrise and sunset times, the mid-point of the program is around the same point during the year. As LumiStep does not make adjustments for the duration of night, during summer months the standard dim period can be as long as the entire on period (Figure 32).

Figure 32. LumiStep dimming profile differences


1-10 V dimming The dedicated Fortimo LED LLM driver for 3000 and 4500 lm systems offers 1-10 V dimming. In addition to direct control of the system via 1-10 V wires, this feature can be combined with SDU device to replicate LineSwitch (pilot line) functionality, or connected to the Philips Dynadimmer for standalone, multi-level dimming. For more information about these controls options, please visit our website: • Philips Dynadimmer • Philips SDU

Constant Light Output

Figure 33. Energy savings with CLO

The Fortimo LED LLM system is equipped with the Constant Light Output (CLO) feature, which results in lumen maintenance of 100% at 50,000 hours (typical lifetime specification). This saves energy over the lifetime of the luminaire, preventing over-lighting at the beginning of the installation (Figure 33). CLO reduces energy consumption and improves system reliability. The CLO feature uses a predictive algorithm to increase the output current to the module over the specified lifetime of 50,000 hours. As the current increases, energy consumption also increases. The CLO feature can be combined with other dimming protocols for even greater energy savings. When Fortimo LED LLM modules are used with non-dedicated Xitanium drivers, the CLO curve needs to be programmed. For the required inputs, please refer to Table 10 below. Between these points, linear interpolation should be used. To simplify programming, the Fortimo LED LLM Gen 3 profiles for both Xitanium Prog and Prog+ LED drivers is available on request from your Philips sales representative.

Installation instructions

Warning! The Fortimo LED LLM Gen 3 should always be replaced by a trained installer. Special attention should be paid to the following points: • Do not service the system when the mains voltage is connected;

this includes connecting or disconnecting the cable • Before a new Fortimo LED LLM Gen 3 is mounted, the old

thermal interface must be removed and the area must be cleaned

Mechanical fixation The separate components (driver and module/s) of the Fortimo LED LLM Gen 3 system can be fixed in place securely using the mounting holes located on the module(s) and driver. Please refer to the dimensional drawings for specific details. The 3D CAD files can be downloaded from the Fortimo LED LLM website. For fixation of the system we advise using an M4 hexagon socket head cap screw (DIN 912 / ISO 4762) with an M4 spring lock washer for screws with cylindrical heads (DIN 7980) of A2 stainless steel (DIN 1.4301 / AISI 304). It is not allowed to use screws with a head diameter larger than 8 mm.

Fixation of the module

Figure 34. Fixation of the LLM Gen 3 module

Before fixing the Fortimo LED LLM module, ensure that the mounting surface is clean and flat, without any protrusions or pits. To ensure a reliable thermal and mechanical attachment, we recommend that the flatness of the mounting surface should be ≤0.2 mm. For the best thermal performance, use a thin layer of thermal paste between the module and the mounting surface. The entire bottom surface of the module needs to be covered with thermal paste, with a typical bond line of 30 to 50 microns. Other thermal interface materials can be used but will require more cooling from the luminaire (i.e. more contact surface between the luminaire and the ambient air).



Fixation of the driver

The Xitanium driver has screw holes on the short ends of the casing. The driver should be mounted securely on a flat area of the luminaire, using all mounting holes.

Fortimo LED LLM system with dedicated drivers For Fortimo LED LLM 1100 and 1800 lm systems, a cable is available to connect the module

to the driver (Figure 35). For Fortimo LED LLM 3000 and 4500 lm systems, a cable is integrated into the dedicated Xitanium driver. To ensure compatibility with both Gen 2 and Gen 3 modules, an additional interface cable is included with the driver. The interface cable must be connected to the integrated cable of the driver before being connected to the module (Figure 36).

Connecting cables

Figure 37. Connecting cable to module

Mate connectors gently in a straight line, pressing down the whole of the connector. When the mating operation is properly completed there is an audible click. If there is no click, full contact has not been made. Remove the connector and repeat the process. The number of connection attempts should be kept to a minimum. Removing connector cables Press lock-release lever to release the cable connector completely. Remove the connector straight along the mating axis. Do not pull on the cable forcibly without unlocking first; such handling may cause breakage.

Figure 38. Cable wiring to driver

The Fortimo LED LLM Gen 3 is compatible with both Rset1 and Rset2 Xitanium LED drivers. Please note that Fortimo LED LLM modules can only be used in combination with specific Xitanium LED drivers. Please refer to Table 3 for approved combinations. A standard cable is available for connecting the module to a driver. The color coding of the wires in the cable corresponds to the wiring of the Xitanium drivers. When using Fortimo LED LLM Gen 3 modules in combination with Xitanium Programmable LED drivers, it is necessary to activate and program the correct Constant Light Output (CLO) and Module Temperature Protection (MTP) settings. To simplify programming, the Fortimo LED LLM Gen 3 profiles for both Xitanium Prog and Prog+ LED drivers is available on request from your Philips sales representative. Note: • The Rset2 wire should be left unconnected when using Rset1 drivers, and vice versa. • The unused Rset wires should be clipped short and wrapped with an insulating material

e.g. a fiberglass insulating sleeve.

Figure 41. Color coding (two modules connected to one driver)

It is possible to connect two modules in series to one Xitanium driver by using two cables. It is important to note that the driver can only communicate with one of the modules. Because the output current setting and Module Temperature Protection read-out are only available on one of the two modules, it is essential to use modules from the same batch. This will ensure the correct performance of the system. The production date code on the module label identifies the batch.

Warning! • The Rset2 wire should be left unconnected when using Rset1

drivers and vice versa.• The unused Rset wires should be clipped short and wrapped

with an insulating material e.g. a fiberglass insulating sleeve.• When a system consists of 2 LLM modules connected to a single

driver, only one module is monitored by the NTC and RSET• A robust thermal design is strongly advised• Always use 2 modules of the same type and batch

Replacing a module System replacement When replacing modules in a system with Constant Light Output (CLO), it is advisable to replace the complete light engine (module + driver) to ensure correct functionality of the CLO programming. Replacing only the module after the driver has been operational in the field will result in over-lighting.

Replacing a module when 2 modules are connected to 1 driver Special attention is required when replacing a module in a 2-module/1-driver configuration. Since the driver can only read out information from a single module, in the event of failure we recommend replacing both modules, as current settings can vary from batch to batch over time as LED performance improves. If the installer does not replace both modules it is possible that one of them will be driven at the wrong current and will not produce the specified lumen output. The production date code on the module label identifies the batch.


Using a long cable in a Fortimo LED LLM Gen 3 system It is possible to use a connection between the module(s) and the driver that is longer than the standard cable. When using AWG24 cables, the connection can be extended to 10 meters without affecting the power supply to the module. It is not advisable to use the communication wires because of possible interference.

Warning! When using a long cable between module and driver, extra care should be taken in the design of EMI, surge and noise suppression.


Off-grid (solar) applications

Designing an off-grid system

Introduction Fortimo LED LLM modules can be used together with low-voltage DC input Xitanium LED 40W and 70W drivers to create a system for off-grid applications.

The Fortimo LED LLM Solar system is designed especially for off-grid solutions. These systems are not connected to the utility grid.

To facilitate the integration of the modules in a complete solar (DC) system, this section outlines the basic principles of an off-grid solar outdoor lighting system, including how to size a solar system.

Solar system An off-grid solar lighting system typically consists of a number of key components connected electrically and mechanically to each other. In addition to the luminaire, which includes the Fortimo LED LLM and the applicable Xitanium LED DC input driver, the other key components are the solar panel, the battery, and the charge controller.

Solar panel A solar panel is a packaged interconnected assembly of photovoltaic cells (a solar cell is the basic component used in the manufacture of solar modules made from silicon; the cells are manufactured from wafers) and is able to convert light energy (photons) from the sun to electricity through the photovoltaic effect. It is therefore used as a component in a photovoltaic system to supply electricity for commercial and residential applications. The photovoltaic cells are usually made of silicon, organic materials or cadmium telluride. The efficiency of a photovoltaic cell varies according to the material used.

Monocrystalline solar panels The most efficient and expensive solar panels are made with monocrystalline cells. These solar cells use high-purity silicon and involve a complicated crystal growth process. Long silicon rods are produced which are cut into 0.2 to 0.4 mm-thick discs or wafers, which are then processed into individual cells that are wired together in the solar panel.

Polycrystalline solar panels Often called multicrystalline, these solar panels, made with polycrystalline cells, are a little less expensive and slightly less efficient than monocrystalline cells because the cells are not grown in single crystals but in a large block of many crystals. This is what gives them that striking shattered glass appearance.

Amorphous solar panels These are not really crystals, but a thin layer of silicon deposited on a base material such as metal or glass to create the solar panel. These amorphous solar panels are much cheaper, but their energy efficiency is also much lower, which means more square footage is required to produce the same amount of power as the monocrystalline or polycrystalline type of solar panel. Amorphous solar panels can even be made into long sheets of roofing material to cover large areas of a south-facing roof surface.


An important parameter for a solar panel is the Wp. W = watt, while the p means “peak”, as in peak power. The “p” does not however show the peak power, but rather the maximum output according to standard test conditions (STC). The degree of efficiency of a module/cell is defined as the power per surface area (W/m2). The degree of efficiency has no bearing on the production of a module/cell.

Notes: • Module or panel efficiency is lower than cell efficiency. It is advisable to contact the

panel manufacturer for information about the panel efficiency. Panel prices depend onthe type of photovoltaic cells and can vary substantially.

• The efficiency of a solar panel is temperature-sensitive and depends on the cell typeused.

The battery Batteries are required for off-grid systems, in which the generated energy is stored before it is used.

The battery used in solar lighting systems is a rechargeable battery, often referred to as a secondary battery. A rechargeable battery is an energy storage device which is able to store electricity in a chemical manner. These batteries can be recharged electrically by passing a current through them in the opposite direction to that of the discharge current.

Lead-acid battery is the most widely used battery type in solar lighting systems. The nominal voltage of a cell inside the lead-acid battery is 2.0 V. Li-ion batteries are increasingly being used because of their high energy density and long cycle life. However, the high price of Li-ion batteries is still hampering their use in solar lighting.

The nominal voltage of an LiFePO4-based Li-ion battery is 3.3 V. The battery capacity is related to the battery volume and weight. A battery pack consists of several batteries connected in series and/or in parallel to achieve the desired capacity and output voltage.

Two types of lead-acid batteries are available on the market: AGM and gelled lead-acid batteries. A gelled lead-acid battery has a longer lifetime than its AGM counterpart. The lifespan of a lead-acid battery in a solar lighting system is approximately 2-3 years. The other type, the LiFePO4-based Li-ion battery, is expected to have a lifespan of over 5 years in a solar lighting system.

Rechargeable batteries are usually specified on the basis of the following features: • Nominal voltage (V)• Capacity (Ah)• Cycle life (number of cycles)• Operational voltage range (V)• Operational temperature range (°C)• Maximum continuous charge/discharge current (A)• Maximum pulse charge/discharge current (A)

Battery charger or charge controller The charge controller charges the battery using the energy harvested by the solar panel during the daytime. At night, the stored energy is used to power the LED module as efficiently as possible. The system interfaces are shown in the diagram.

The charge controller ensures that the battery is not overcharged during the day, and regulates energy feed to the LEDs when the luminaire is on.


Battery protection through the charge controller Neither lead-acid nor Li-ion batteries should be over-charged or over-discharged. Over-charging and over-discharging will shorten the battery lifespan or even damage the battery before its specified end-of-life. In some extreme cases, over-charging and over-discharging Li-ion batteries can cause dangerous situations such as a fire and/or explosion. Battery voltage should be strictly regulated by the controller to prevent over-charging and over-discharging. The charge or output current will be cut off when the preset upper or lower voltage limit is reached. Refer to the battery pack’s specification for the upper and lower voltage limits or contact the battery manufacturer directly for the relevant information.

Temperature also has a significant impact on the voltage of lead-acid batteries and needs to be taken into account when designing your solar system. As a guideline, protective voltage should be reduced at high temperatures and increased at low temperatures.

It is important to understand the different technical solutions available and to configure the system correctly. The key parameters are explained in further detail in the following section on how to design a solar system with the Fortimo LED LLM Off-grid system.

Dimming External PWM is an option for dimming the LLM, as explained previously. As a guideline, external PWM and LumiStep integrated into the Xitanium DC input LED driver cannot be used simultaneously. If the integrated LumiStep is active, the channel for external PWM is not connecting the charge controller and the driver. If the external PWM is in use, the integrated LumiStep is automatically de-activated.

Key parameters when designing and sizing a solar system When designing or sizing an off-grid solar system, the most important thing is to make sure the system is designed for the relevant application, location and functional requirements. It is usually advisable to design the system for the worst-case conditions.

Location The location is one of the most important parameters to be taken into account when sizing a solar system. The location determines the number of hours of sun per year, the minimum and maximum ambient temperatures, and also the intensity of the energy coming from the sun (irradiation: kWh/m2). This amount of energy (Wp) will be a fixed input and will be crucial in the design of the system. There are several sources where this information can be obtained, one of which is the NASA website.

Power consumption Another given input which is key and fixed when the system is being designed is the power consumption of the total street lighting system, including Fortimo modules, drivers, battery controller and any other power consumption involved in the system. Note that the power consumption depends on the operating hours required per day, the autonomy required (days) and the dimming profile (LumiStep program), which enables energy to be used more effectively by using less power when less light is needed.

The power consumption of the solar system, the operational time per night and the dimming level jointly determine the total energy consumption of a system each night. This is a key parameter for correctly choosing the right size of solar panel and the capacity of the battery pack.

http://eosweb.larc.nasa.gov/cgi-bin/sse/[email protected]


Back-up time required The back-up time (often known as autonomy) is usually meant to cover the worst-case predicted number of consecutive overcast or rainy days when insufficient solar energy can be harvested. The required back-up time is often stated in days and is crucial for determining the capacity of the solar panel and battery pack. The longer the back-up time, the higher the battery capacity and solar panel size.

Orientation of solar panel Optimum orientation of the solar panel enables you to get the most from it by capturing maximum solar radiation. Solar panels should always face true south in the northern hemisphere and true north in the southern hemisphere. The most important factor is the angle of tilt from the horizontal at which the solar panel is fixed. Two factors affect the angle of tilt: • Latitude• Seasons

As a general guideline, the tilt angle increases with higher latitude. For example, at the equator the panels are almost horizontal, while to the north or south they are more vertical. The angle of tilt is also usually optimized for winter because this is when there are fewest hours of sunshine per day.

The size of the solar panel The solar energy harvested by the solar panel during the daytime should be enough to at least cover the energy consumption for one night. The solar energy that can be harvested depends on the solar irradiation level (Wh/m2/day) and the size and efficiency of the solar panel. The level of solar irradiation varies according to the season and location. The solar panel efficiency varies according to the cell types and quality. The above three factors are the most important factors to consider when choosing the size of solar panel to be used in a given system.

How to design your solar system? For a practical solar system, the following parameters have to be decided: • Working profile of the fixture (operating hours and dimming levels) and power

consumption• Solar panel peak voltage (Vmp), peak current (Imp), peak power, size and quantity• Battery voltage, capacity, quantity and connection options• Type of charge controller and working parameters• Location of the parts in the system, such as the solar panel, battery and controller

(e.g. battery pack top-mounted, buried, etc.)

System design procedure The following design procedure is recommended when a solar system is being designed. 1. Collect information about the environment in which the system is to be located2. Confirm the requirements and expected performance of the system3. Calculate the energy load of the lighting system4. Decide on the battery solution for the system5. Determine the solar panel solution to be used6. Select an appropriate controller1. 7. Decide on the system installation architecture


Reference system design This section presents a reference off-grid solar system using Fortimo LED LLM 1800 lm, which is typically used for solar powered systems in off-grid areas.

Step 1: Collect information about the location environment Example: Geography: longitude east 106.72, latitude north 26.57 Daily averaged radiation incident on horizontal surface (kWh/m2/day) Temperature: highest <35 °C; lowest >-5 °C Altitude: around 1200 meters

There are various public sources that provide data relating to the energy generated by the sun. Data are available on the NASA website: http://eosweb.larc.nasa.gov/cgi-bin/sse/[email protected].

Step 2: Confirm requirements and expected performance of the system Expected autonomy time (days without solar charging): 6 days. System operation profile: switch on at sunset and switch off after 6hrs.

Step 3: Determine the power consumption of your chosen Fortimo LED module and driver Fortimo LED Linear Light Module (LLM) Solar 1800/740 17W Gen 3 Xitanium 40W LED driver 0.2-0.7A LS 12-24V

Step 4: Calculate the energy load of the lighting system per night The Fortimo 1800 lm 4000 K module consumes 17 W. Taking 10% driver efficiency loss into account, the power consumption per night can be calculated as follows: E = (17 + 1.7)W * 6h = 112Wh

Note: This example excludes additional savings which can be achieved by the programmable LumiStep functionality

Step 5: Decide on battery solution for the system Define type of battery: • 12 V GEL lead-acid battery

Define required battery capacity, which is affected by: • Lighting system’s energy load per night• Back-up time• GEL max. Depth of Discharge (DoD), here 70%• GEL discharging efficiency; here we use 95%• Low temperatures (<0 °C) have an impact on the effective capacity of the battery. This

effect is not included in the illustrative calculation

Required capacity is: 112Wh/night * 6 nights / (95% * 70%) / 12V = 84Ah One standard 12V/ 84Ah GEL is required.

http://eosweb.larc.nasa.gov/cgi-bin/sse/[email protected]


Step 6: Determine the solar panel solution to be used Solar panel parameters are determined and affected by: • The panel mounting direction and angle of tilt• Energy load of the lighting system per night• The battery charging and discharging efficiency; here these figures are 85% and 95%respectively• Sun radiation on solar panel surface• Battery voltage and solar panel voltage temperature coefficient• Margin factor; here it is 1.1

The angle of tilt can be calculated on the basis of the monthly average sun radiation data. In this case it is 40 degrees, pointing towards the equator, and, as a result, the daily sun radiation is 1.8 kWh/m2 per day.

Required peak current: 1.1 * 112Wh / (95% * 85% ) / 12V / 1.8h = 7A

The peak voltage of a standard off-grid solar panel for a 12 V lead-acid battery is around 17.5 V. A simple calculation indicates that even with a 35 °C ambient temperature, 0.5 V voltage loss on cables and anti-reverse charging diode, 17.5 V is good enough for a GEL battery solution.

The solar panel power requirement is: 17.5V x 7A = 123Wp

Step 7: Select an appropriate charge controller To meet the application requirements, the controller has the following features: • Over-charging protection• Over-discharging protection• Temperature protection• Battery temperature compensation• Dusk & dawn automatic recognition• Timer control

• 12/24 V automatic selection• Input current level

The input voltage from the controller needs to be higher than the Voc of the solar panel, i.e. >22 V. Its input current should be at least 25% higher than the Isc of the solar panel, i.e.>1.25 * 2 *5.1A = 12.75A

The selected controller: Phocos CIS 20/12/24, max. 20 A.

Step 8: Decide on the system installation architecture The installation architecture can be designed in different ways: • Battery: buried in the ground, half-way up the pole, on top of the pole; when deciding on

location take temperature, IP rating and theft/vandalism into account• The charge controller can be mounted close to the battery, in the pole or in the

luminaire; when deciding, take the losses on the cables and cost into account• Solar panels are normally mounted on top of the pole in parallel.

Cable for off-grid applications A specific cable has been developed for connecting a 40W Xitanium driver to a Fortimo LED module. The standard length of the cable is 50 cm. We recommend using the Fortimo LED Solar cable. If a different length of cable is required, this has to be sourced independently. Special attention needs to be devoted to compliance with the UL and IEC/EN requirements if the length of the cable is extended. Approval of the Fortimo LED module and Xitanium is based on a reference luminaire with the standard cable length of 50 cm. Any luminaire design requires specific approval, to be arranged by the OEM, irrespective of the length of cable used. If a cable with a different length is preferred, the necessary cable/connector specifications are indicated in Table 16.

Programmable LumiStep (LS) dimming To enable even further energy savings, programmable LumiStep has been integrated into the Xitanium DC input LED driver. This stand-alone feature enables the light level to be dimmed for a specified period each night. This provides maximum flexibility in terms of dimming requirements for ‘off-grid’ systems, depending on where the system is located. The ‘dynamic’ LumiStep automatically calculates the profile based on the mid-point of the night. As most stand-alone solar systems are based on sunrise and sunset times, the mid-point of the program is re-calculated throughout the year.

• Intelligent timing, autonomous operation: reference points are the switch-on andswitch-off times and dynamic mid-point of the night

• The functionality integrated into the Xitanium LED driver can be programmed byOEMs (see Appendix B)

• The LumiStep functionality is disabled by default and the system will not dim during thenight

• The lowest dimming level is 10%

The Fortimo LED LLM off-grid system uses a PWM (pulse width modulation) amplitude dimming protocol, which means that the current is switched on/off at high frequency. The cycle time is fixed when dimming.

The intelligent LumiStep functionality can be programmed with software. Appendix B provides more information on how to program the Xitanium LED driver.

Note: When installing a pre-programmed LumiStep system for the first time it will take three nights for the system to stabilize (power-on time per night > 4 hrs) before dimming starts.

External dimming via PWM Depending on the charge controller being used, dimming levels can also be managed by a separate (charge) controller via an external interface based on PWM communication. The characteristic of the PWM signal is as follows: Frequency: 250 Hz Amplitude: 5.0 V Lowest dimming level: 10%

Warning! When an external signal is detected, it will overrule the programmed LumiStep integrated in the LED driver. The frequency and amplitude of the external PWM signal need to be fixed. Various dimming levels can be set by altering the on-off time ratio of the PWM signal (duty cycle).


Quality

Compliance and approval marks The Fortimo LED LLM Gen 3 system is ENEC certified, and complies with CE regulations. To ensure luminaire approval, the conditions of acceptance need to be fulfilled. Module-related data can be found in IEC 6203. All luminaire manufacturers are advised to conform to the international standards of luminaire design (IEC 60598).

Sustainability The Fortimo LED LLM Gen 3 system is compliant with RoHS and REACH requirements.

Conditions of acceptance Details can be requested from your local sales representative.

IP rating, humidity and condensation Fortimo LED LLM Gen 3 systems are build-in systems and therefore have no IP classification. They are not designed for operation in the open air. The OEM is responsible for proper IP classification and approbation of the luminaire.

Warning! The Fortimo LED LLM Gen 3 has been developed and released for use in dry and damp locations. • Do not use in locations where condensation is present• If there is a possibility that condensation could come into contact with the

modules, the system/luminaire builder must take precautions to preventthis.

Photobiological safety The photobiological safety standard IEC 62471 (‘Photobiological safety of lamps and lamp systems’) gives guidance on evaluating the photobiological safety of lamps and lamp systems, including luminaires. This standard specifies the exposure limits, reference measurement technique and classification scheme. It should be used for the evaluation and control of photobiological hazards from all electrically powered, incoherent broadband sources of optical radiation, including LEDs, in the wavelength range of 200 to 3000 nm. The following hazard categories are defined:

Radiance-based • Blue Light LB 300 – 700 nm • Retinal Thermal LR 380 – 1400 nm • Retinal Thermal Weak Stimulus LIR 780 – 1400 nm

Irradiance-based • Actinic UV Skin & Eye ES 200 – 400 nm • Eye UVA EUVA 315 – 400 nm • Blue Light Small Sources EB 300 – 700 nm • Eye IR EIR 780 – 3000 nm

Appendix B: Programming off-grid (solar) driver

Figure 48. Xitanium LED driver for off-grid applications

Introduction The Xitanium DC input LED driver for off-grid applications includes a programmable LumiStep feature. By default the LumiStep feature is disabled. This section describes how to program the LumiStep feature in the driver using a standard PC or laptop.

Fortimo Solar GEN1 configuration interface The configuration interface is designed to be operated with any VT100 terminal or a PC with a program such as HyperTerminal. It is comprised of a serial connection using a UART operated at 1200 baud, 8 data bits, 1 stop bit, no parity, and no flow control. It will ignore a BREAK condition.

The off-grid Xitanium LED driver can be connected to a USB port of a PC by the TTL-to-USB serial converter cable TTL-232R-3V3-AJ (FTDI Chip).

Figure 49. Program audio jack plug connector

The Virtual Com Port driver of FTDI Chip (version 2.06.00 or higher) should be installed on the PC. Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would a standard COM port. This driver can be downloaded free of charge from the FTDI Chip website (http://www.ftdichip.com/FTDrivers.htm). The installation guide for the driver can be found at http://www.ftdichip.com/Documents/InstallGuides.htm.

After the driver has been installed, plug the TTL-to-USB serial converter cable into one of the USB ports of the PC. This USB port now appears as USB SerialPort (COMn) in the Ports list of the Device Manager:

http://www.ftdichip.com/Documents/InstallGuides.htm


(continuation…. ‘This USB port now appears as USB SerialPort (COMn) in the Ports list of the Device Manager’:

On the PC, start HyperTerminal and set up a new HyperTerminal connection:

Select the USB Serial COM port (COMn) in the Connect To tab of the HyperTerminal properties:


Set the Port Settings to 1200 baud, 8 data bits, no parity, 1 stop bit and no flow control:

Click on File Properties In the Settings tab, select Emulation: ANSIW


Select ASCII Setup Check Send line ends with line feeds and Echo typed characters locally. Enter 1000 milliseconds in Line delay: Use the defaults for the other values.

Recognized characters and controls The following control characters are handled:

Any whitespace (e.g. space, tab, line ending)

Whitespace separates commands

[Enter] Executes the current command line [Backspace] Removes the previous character

Note: The current implementation does not have a lot of buffer space, so you cannot backspace over whitespace. If you do, the current command line will be canceled as if you had pressed [ESC].

[ESC] Cancels the current command line.

Parameters to commands can also be numbers, including hexadecimal (starting with 0x or 0X) and octal (starting with 0).

Basic commands The basic commands are:

‘get’ : Read a value ‘set’ : Set a value ‘do’ : Perform an action ‘list’ : Print these commands

Basics The debug interface commands are case sensitive.

Syntax error When an unrecognized command is entered, the interface will return ‘Syntax error :<command>’.


Available commands The ‘list’ command is used to print all available commands. Entering ‘get list’ will display and if necessary print all available commands that can be entered after the ‘get’ command.

Getting and setting an alternative ‘base’ for numbers Numbers are printed as decimal numbers by default, e.g. with a base of 10. (itoa is used for conversion.) When desired, an alternative base can be chosen. For example: 16 for hexadecimal representation.

The base for printing numbers can be set by ‘set base‘, followed by a number representing the new base Setting ‘set base’ to 0 or less will set the base to 10. Setting ‘set base’ to 10 will cause negative numbers to be prefixed with ‘-’. Setting ‘set base’ to 1 will cause an infinite loop, terminated by a watchdog reset. Setting ‘set base’ to 8 will cause all numbers to be prefixed with ‘0’. Setting ‘set base’ to 16 will cause all numbers to be prefixed with ‘0x’. Setting ‘set base’ to more than 36 will cause printing of ASCII characters after ‘Z’ in the ASCII table.

The base for printing numbers can be read by ‘get base’ The base will always be returned as decimal, e.g. with a base of 10. Resetting the device will reset the base to 10.

‘get’ commands The ‘get’ commands for LumiStep are:

‘periodsize’ Reads the number of dim periods for LumiStep Range: 0 – 16; if it is 0, LumiStep is disabled

‘dimlevel [index]’

Reads the dim level setpoint of period [index] during LumiStep. 0%-100%=0-65535. [index] has range 0 – 16.

‘dimdur [index]’

Reads the times at which a new dim period of LumiStep will start, in minutes. Values are times relative to the night mid-point (negative when a dim period starts before the night mid-point). If all periodsize-1 values are 0, LumiStep is disabled. [index] has range 0 – 15.

‘fadetime’ Reads the time required to fade from one dim level to the next, in seconds.

‘version’ Prints the version string ‘base’ Reads the base value for printing numbers, as a decimal

number. ‘list’ Prints the list of commands.


‘set’ commands The set commands for LumiStep are:

‘periodsize’ Sets the number of dim periods for LumiStep. Range: 0 – 16; if it is 0, LumiStep is disabled. The value is written to non-volatile memory.

‘dimlevel [index]’

Sets the dim level setpoint of period [index] during LumiStep. 0%-100%=0-65535. [index] has range 0 – 16. The value is written to non-volatile memory.

‘dimdur [index]’

Sets the times at which a new dim period of LumiStep will start, in minutes. Values are times relative to the night mid-point (negative when a dim period starts before the night mid-point). The dim times as a function of index should be in strictly ascending order. If all periodsize-1 values are 0, LumiStep is disabled. [index] has range 0 – 15. The value is written to non-volatile memory.

‘fadetime’ Sets the time required to fade from one dim level to the next, in seconds; range 0 – 536; higher values are clipped to 536. The value is written to non-volatile memory.

‘base’ Sets the base value for printing numbers, as a decimal number.

‘list’ Prints the list of commands.

‘do’ commands The ‘do’ commands for LumiStep are:

‘reset’ This command will reset the device. ‘list’ Prints the list of commands.

Examples Figure 47 shows an example of a LumiStep profile. This profile is programmed with the following commands:

‘set fadetime 450’

Set fadetime to 450 s.

‘set periodsize 3’ Use three dim periods ‘set dimlevel 0 65535’

Start at 100% light level.

‘set dimdur 0 -120’

Start first dim period 2 hours before mid-point of night

‘set dimlevel 1 39321’

Dim level of first dim period is 60%.

‘set dimdur 1 30’ Start second dim period 0.5 hours after mid-point of night. ‘set dimlevel 2 26214’

Dim level of second dim period is 40%.

‘set dimdur 2 300’

Start third dim period 5 hours after mid-point of night.

‘set dimlevel 3 52428’

Dim level of third dim period is 80%.


Figure 50. Sample programmed LumiStep profile

Notes: • These dim settings take effect only after restart of the driver, and

when a sufficient number of valid nights have been detected• Pressing Enter after programming a character saves the number• Do not use capitals

Additional LumiStep programming methodA new programming tool for LumiStep called Fortimo Solar Configuration has been developed since Windows 7, 8 and 10 do not include HyperTerminal anymore. This new tool allows for a more user-friendly configuration of a required LumiStep scene for the 40W and 70W driver.

Setting up a LumiStep sceneUp to seventeen individual dimming steps can be defined for a LumiStep scene from the Lumi steps dropdown list, each step having its own dimming level in % and dimming duration in minutes. An optional fade time can be configured in seconds.

Before configuration can start, the driver must be powered up (connection of a a LED module not required) and connected to a USB port with the TTL-to-USB serial converter cable TTL-232R-3V3-AJ (FTDI Chip). See page 45 for more details. The correct COM port then needs to be selected.

Configuration exampleApplication requirements:

1: full light output during the first 4 hours after power-on

2: dimming to 50% for 3 hours with a fade time of 2 minutes.

3: full light output for 4 hours.

The corresponding scene must be created like the one shown on the left in fig. 52. by choosing the number of steps from a dropdown menu and typing in the values for the level, duration and Fade time.

Once scene creation input has finished, the driver can be configured accordingly by clicking on the button "Write to driver". A write progress bar will occur, followed by a pass/fail notification before configuration has finished.

Philips will perform the testing of the LED systems to high standards of workmanship. The tests are carried out with reference to the EN/IEC standards, if any, which are regarded by Philips as being of major importance for the application of the lamp gear and the lamp within the fixture for horticultural applications.

The design-in guide, regarding the testing and design in of the LED system provided by Philips, is not an official testing certificate, and cannot be regarded as a document for official release of the fixture. The OEM is liable for the official testing by a certified test body and all markings, such as CE and ENEC marks, on the fixture assembly.

The design-in guide is for information purposes only and may contain recommendations for detecting weak points in the design of the system (lamp – lamp gear – fixture), if any.

Specifically mentioned materials and/or tools from third parties are only indicative: other equivalent equipment may be used but it is recommended that you contact Philips for verification.

Philips will not be liable for unforeseen interactions of the proposed solutions when applied in the fixtures or applications using these fixtures. Philips has not investigated whether the recommendations are or will in the future be in conflict with existing patents or any other intellectual property right. Philips does not warrant that its recommendations are technically or commercially the best options.

Since the tests are only performed on one particular fixture provided by the customer, it will be treated as a prototype. This means that there is no statistical evidence regarding later production quality and performance of the lamp – lamp gear – fixture system.

As Philips does not have control over manufacturing of the fixtures, Philips cannot be held liable for the fixture assembly.

Philips will not accept claims for any damage caused by implementing the recommendations.

No warranty whatsoever may be claimed by the OEM with regard to the content and/or quality of the design-in guide or any other advice, or the conclusions and/or recommendations in the design-in guide or any other document, either express or implied, and Philips expressly disclaims any implied warranties of any kind, including without limitation any warranties of satisfactory quality, fitness for a particular purpose or non-infringement and any warranties regarding the design-in guide or any other advice or the use of the results of any activity performed while testing the fixture with respect to its correctness, quality, accuracy, completeness, reliability, performance or otherwise.

The OEM expressly agrees that test design-in guides are provided by Philips on an ‘as is’ basis and an ‘as available’ basis at customer’s sole risk and expense. Philips shall not be liable for any lost profits or lost savings, indirect, incidental, punitive, special, or consequential damages whether or not such damages are based on tort, warranty, contract, or any other legal theory – even if Philips has been advised, or is aware, of the possibility of such damages.

The OEM must bring any claim for damages within ninety (90) days of the day of the event giving rise to any such claim, and all lawsuits relative to any such claim.
