SHARP high-powered ZENIGATA LED, comprising LED chips mounted on an 18mm-square ceramic substrate, ensures broad luminous flux, high light-emitting efficiency and radiation performance, and achieves high reliability.

Z ENIGATA LED is suitable for lighting apparatuses shown below.• Incandescent lamp• Spotlight• Downlight• Pendant light• Landscape light• Road lighting

Since the light emission from ZENIGATA LED includes less infrared light (heat ray) than that from a conventional incandescent lamp, ZENIGATA LED is adaptable to the lighting of commodities susceptible to damages caused by temperature rise. It is also suitable for the lighting of goods of concern for bad influences due to ultraviolet ray, including discoloration, since the light from ZENIGATA LED is free from ultraviolet ray.In these days, amid mounting environment concerns, l ight sources having broader luminous flux per electric power and longer service life leading to less replacement intervals are required. LEDs, having features such as superior light emitting effi ciency and longer life allowed by high reliability, are expected to make contributions to environmental conservation, including energy-saving and reduction of wastes. ZENIGATA LED, combining favorable features of LEDs, such as high light-emitting effi ciency and longer life, has potential of an environmental-friendly key lighting device in a new era.

This guide introduces characteristics of ZENIGATA LED and describes some notes on use showing reference case examples.

Temperature characteristics of ZENIGATA LEDSince the luminous flux, forward voltage and color of LED fluctuate depending on the temperature, temperature (range) in actual use must be recognized for design.Be sure to design it so that the temperature is within the range shown in page7.

Increase in temperature or current may accelerate degradation of LED, and lead reduction of light emission and effi ciency, and fl uctuation in color temperature.Thus, operation of LED in high temperature is unfavorable, and suffi cient provision of radiation design by heat sink is recommended.

Heat design of ZENIGATA LEDOperation temperature of ZENIGATA LED is detected at the soldering pad position as case temperature Tc. When mounting ZENIGATA LED, case temperature Tc must be controlled within the forward current reduction curve.

Since ceramic is an insulating substrate, ZENIGATA LED can be directly mounted on a heat sink. To make sure heat radiation, radiation silicone paste or radiation sheet must be insulted between ZENIGATA LED and heat sink.The drawing left below shows the mounting status. Viewing through thermography, it shows temperature of ceramic substrate portion is close to that of heat sink. It means heat generated from LED translates to heat sink smoothly.

Circuit DesignZENIGATA LED is used for applications such as bulb, dawn light and street light by optimum circuit design. Constant voltage power supply runs off more than specified current amount due to lowered VF caused by temperature rise.Constant current power supply is recommended to drive.In designing a circuit, please make sure not to give reverse voltage to the LEDs at any time.When ZENIGATA LEDs are connected in series, adapt protection device like zener for each ZENIGATA LED. Make sure to be confi dent of the safety standards or regulations in each location and area.

Featured Application

■ Usage conditionsThe products are not designed for the use under any of the following conditions.Please confirm their performance and reliability well enough if you use under any of the following conditions;• In a place with a lot of moisture, dew condensation, briny air, and corrosive gas

(C1, H2S, NH3, SO2, NOX, etc.).• Under the direct sunlight, outdoor exposure, and in a dusty place.• In water oil, medical fl uid, and organic solvent.

■ InstallationMaterial of board is alumina ceramic.If installed inappropriately, trouble of no radiation may occur due to board crack.Please take particular notice of install method.Further information on installation, refer to the following cautions.• Apply ether screws or adhesives, or both of them when installed to heat radiator.

In case of applying adhesive only, check the effectiveness before fi xing.In case of screw, apply thread locker in order to prevent loosening.If LED comes off from the heat radiator, unusual temperature rise entails hazardous phenomena including device deterioration coming off of solder at leads and emitting smoke.

• Screw torque:Within 0.2NmIf it is ineffi cient to tighten screws, apply locker to prevent loosening.

• It is recommended to apply screws which use low corrsive materials such as Stainless steel.Avoid applying fl at-head screws, which cause board crack due to applying stress to screw holes.

• Avoid convexly uneven boards.Those convex boards are subject to crack when tightening screws.

• It is recommended to apply thermal conductive sheet or grease with adhesiveness and heat radiating-adhesives, because of thermal and mechanical combination between module and heat radiator.However, depending on their thickness, board crack may be entailed by warped board, which is caused when tightening screws.So please check your actual conditions carefully as for the screw torque.

■ Connecting methodIn case of solder connecting method, apply solder to the leads by soldering iron with thermo controller(tip temperature380°C), within 10seconds per one place.Put the board on materials whose conductivity is poor enough not to radiate heat of soldering.Avoid touching yellow phosphor with soldering iron.This product is not designed for refl ow and fl ow soldering.

■ SafetyLooking directly at LEDs for a long time may result in hurt your eyes.In case that excess current(over ratings)are supplied to the device, hazardous phenomena including abnormal heat generation, emitting smoke, or catching fi re can be caused.Take appropriate measures to excess current and voltage.In case of solder connecting method, there is a possibility of fatigue failure by heat.Please fi x the leads in such case to protect from short circuit or leakage of electricity caused by contact.Please confi rm the safety standards or regulations of application devices.
