LED lamp technology and its development trend

With the continuous improvement of LED application technology and the gradual decline of cost, LED lamps in the automotive electronics after recent years of technical verification, concept car display, such as the initial stage of the idea, more and more close to the large scope of the production vehicle system in the bright future. From the Audi R8 Electronic system full use of LED lights start, to Mercedes, BMW, Cadillac, Toyota and other companies also launched their own LED lamp replaces the traditional Bai Zhiguang, hid lamp car models, all kinds of colorful LED lamps for the new car color a lot, attracted the attention of the vast number of consumers, at the same time, also for the future of the car design to provide a new bright spot, I believe there will soon be more auto manufacturers will be LED lights as automotive lighting, indication, backlight and decoration of choice.

LED is suitable for various lighting applications in automotive electronics, including LED headlamps (far light and near light), LED fog lamp, LED taillights, LED brake lights, LED steering lights, LED daytime driving lamp, LED pedal lighting, led car lighting, LED lights, navigation, entertainment systems, instrumentation backlight and lights. LED lamps are used in automotive systems mainly have the following advantages: First, the color saturation is high, so that the output light is more clear and gentle, in line with the automotive headlamps application characteristics; second, long service life, durable, anti-seismic strong, can exceed 20,000 hours, while the traditional halogen lamp life generally in 300 hours or so; Thirdly, the efficiency of high, less additional loss, compared with the traditional lamp of complex cooling system, can be seen LED lamp heat loss is much smaller, the conversion efficiency can reach 85%%, Especially suitable for the future automotive focus on energy-saving design concept; Fourthly, the response speed is fast, unlike the traditional Bai Zhiguang, the HID lamp needs a longer driving point of light delay, more real-time reflection of the condition and road conditions, leaving the driver longer judgment time, reduce car safety accidents; fifth, small size, light weight, can achieve a more compact and refined lamps, for other models to save more space design; sixth, led lamp belongs but color is very good light source, no infra-red, ultraviolet rays, other light, heat, radiation, Suitable for automotive indoor lighting, backlight application requirements.
