MOORE LAMP.2 .Visible light ranges from the basis for our vision is 380 780 mm3 .The incandescent lamp is called THERMAL RADIATOR..4 .High voltage fluorescent tube works on the principle of ? LOW PRESSURE GAS DISCHARGE5. which gas does not allow much scope when it comes to producing different colours ? RARE GAS DISCHARGE6 . 1ST telescope wesre designed by ? DUTCH LENS GRINDERS7 . The luminous efficacy of low pressure discharge lamps is mainly dependent on LAMP VOLUME.8 . uniform illumination for larger areas suitable for ? ACCENT LIGHTING 9. the first competitor to the argand lamp was ? GAS LIGHTING 10. more and whiter light was produced using TEMPERATURE radiation methods.11 . the INCANDASCENT LIGHT the bright was produced by creating voltage between two carbon electrodes12 . who was the founder of the institute of lighting technology in karisruhe ? JOACTIOM TEICMULLER13 . an architectural construction can function similar to an ? ASTRONOMICAL CLOCK14 . The oil lamp was invented by ? FRANCOIS ARGAND15 . Teichmuller defined the term LICHTARCHITEKTUR16 . who described architecture as the correct and magnificient play of masses brought together in light LE CORBUSIER17 . Depending on lamp type and wattage the temperature of the filament can reach up to ? 3000 K18 . Which is used for the manufacture of filament wire? 3653 K19 . What is the characteristic feature of incandacscent lamps ? LOW COLOUR TEMPERATURE 20 . Incandascent lamps can be easily ? DIM MED21 . Which increases the luminous efficacy by upto 40 %? DICHROIC COATING 22 . Incandescent lamp the filament is located INSIDE glass bulb23 . Which is not have so much the melting point of the tungsten ? HAALOGEN LAMPS24 . Temperature of the outer galss envelope has to be over ? 250 deg25 . whih increase the luminous efficiency by upto 401 DICHROIC COATING26. Depending on lamp type and wattage the tmperture o the filament can reach upto 3000 k27.incandesent lamps can be easily DIM-MED

28.Meeting point of tungstant filament 3653 k29. exposed incandescent and flurisent lamps were replaced by a variety of specialized REFLECTOR LUMINARIES30. The size of the rooms was also determined by the availability of NATURAL LIGHTING AND VENTILATION 31. Current pass through conductor gives GOOD RESISTANCE32. INCANDESCENT LAMP is thermal radiator33. Tungsten filament has HIGH MEETING POINT34. Efficiency of incandescent light is 15-20%35.Point source lamp is SPOT LAMP36. The light in space was first introduced by PHILIPPE BOZZI IN 198937. Luminance is measured in FOOTLAMBERT OR CANDELA PER SQUARE METER38. A light color will reflect a GREATER percentage of incoming light waves39. A dark color light reflect a LESSER percentage of incoming light waves40. In IESNA the incident use of illuminance level is 200 LUX41. The two types of photoreceptor cells RODS AND CONES42. The internation dark sky association was founded in 198843. THE EDUCATION OF THE VIRGIN painting illustrate the emotive power of a light 44. The effect of an enclosed space can be created only by LIGHT45. LIGHT is electromagnetic radiation 46.ELECTRO MAGNECTIC SPECTRUM is greater continousrange of radiation47. The range of wavelength for ultraviolet and infrared radiation in 380 AND 780 NANOMETER48. color that can be defined by single wave length are called MONOCHROMATIC49. Color temperature of light source are measured in KELVIN50. The complete lighting unit is termed as LUMINAIRE51.Fluroscent lamp has an life span of 12000 HOURS52. RED hue is warm color53.BLUE hue is cooler color54. The S.I unit of luminous is CANDLE PR SQ.M55. The german name for glasses is BRILLE56. INCANDESCENT LAMP is thermal radiator57. FLUORESENT LAMP is low pressure discharge lamp58. The melting point of tungsten in 3653K59.ABSORPTION is primarily used for shielding light sources.60.The coating that helps to increase the luminous efficiency in incandescent lam upto 40% DICHORIC COATING
