Gm has announced its Cadillac ELR external light source all use leds, this will be the world’s first paragraph exterior lighting all use LED as light source, electric vehicle, is once again in the applications of LED like dimmable led light bulb in the field of automotive, automotive lighting LED the trend of more and more obvious. Believe in the near future the LED light source will cover all low, medium and high-grade cars, to get the most comprehensive popularization.
At present, the LED before application in automobile industry has risen from the automotive interior lighting to the external application of color LED application in car interior lighting such 5W LED Candelabra bulbs has been very mature, such as used in the dashboard, backlight lighting switch, auto reading lamp or looked up and display system, etc. The personage inside course of study says, in addition to the common used tail lights, high brake lights, etc., may large-scale application of LED lights, back light, in the near future. The report, released in accordance with the relevant agencies, is expected to 2013 about 95% of new cars in the world will be in one or more rear lights using LED lighting.
LED with its energy-saving, environmental protection, longevity, seismic, the advantages of small volume, fast response gradually opens the automobile of 5w led candle bulb. In terms of technical level, LED car light demand higher than general lighting lamps and lanterns, the need to satisfy the high brightness output and maintain the junction temperature of 120 ℃ or less, in this way, application in automobile LED lamps and lanterns of lighting system cost, higher prices and bigger difference with traditional lamps and lanterns, such as a high-grade car, incandescent lamp combined taillight price is RMB 120 / set, and the combination of LED taillight is RMB 210 / set. High costs restricted the commercial development of LED auto lamps and lanterns. Facing the huge potential in the field of LED applications in automotive lighting, the author thinks that on the premise of ensuring product quality will reduce the price of the LED lamps and lanterns is the mainly concerns the future development of LED auto lamps and lanterns.
