The era of LED lights is about to open

Not long ago at the Geneva motor show, the third-generation Audi TTCoupe introduced LED headlights to officially meet with the media. The exquisite LED headlights replaced the original xenon lamp assembly and became a highlight of the auto show. The flowers are similar year after year, and the cars are different year after year. The development of automobile industry technology is changing with each passing day, and new technologies continue to replace old technologies. The direction of the development of the automobile industry is also slowly moving towards intelligent and green environmental protection. The development of automotive light source technology is also the same. At the auto show in recent years, we can see that some models are equipped with various colorful LED lights, which have attracted the attention of consumers. LED ( LightEmittingDiode) It is a semiconductor electronic component that can emit light. The LED lamp, as its name implies, refers to the lamp using LED as the light source. In recent years, LED has been widely used in the field of automobiles due to its high brightness, rich color variety, low power consumption and long service life. Safety and energy conservation are eternal topics in the development of the automobile industry and the core of the development of modern automobile technology. The light signal is the language of the car, and the timely and sensitive light signal is an indispensable guarantee for safe driving. However, due to the poor sight of driving at night, the driver's judgment on the front of the driving will be reduced, and traffic accidents will easily be caused by insufficient light or too bright light. According to the statistics of the National Highway Traffic Safety Administration, although the driving time at night only accounts for 1/4 of the total driving time, the proportion of deaths caused by traffic accidents accounts for 1/2. In addition, the statistics of world automobile safety accidents show that the number of casualties in automobile traffic accidents is over 10 million every year in the world, of which about 500 thousand are killed. Traffic accidents at night are three times that of the daytime, and the accident rate is three times that of the lighting condition. Due to the fast lighting speed of LED lights, it can reflect the vehicle conditions and road conditions in real time, leaving drivers with longer judgment time. According to the measured speed of 100 kilometers, the rear car can shorten the braking distance by 7. 5 meters. Effective prevention of rear-end collision and reduction of automobile safety accidents are of positive significance for improving the active safety of automobiles. Industry experts said. In addition, LED has controllability, such as light type, irradiation range and brightness can be linearly adjustable, while traditional xenon lamps cannot. In recent years, LED technology has been continuously developed, technical shortcomings have been continuously overcome, and LED lamps have become more and more intelligent. For example, the LED headlights of some models are equipped with a vehicle-to-vehicle detection radar and a control computer. Even if the driver turns on the high beam for a long time, the light type of the light will be automatically lowered and even the brightness will be reduced. Energy saving and environmental protection is another significant advantage of LED lamps. According to the plan of the Ministry of Industry and Information Technology, by the end of 2015, automobile lighting needs to complete the carbon dioxide emission reduction target. As LED lamps are cold light sources, they have the advantages of low power consumption and long service life. The power consumption is only 1/10 of that of traditional lamps, which can better save fuel consumption. It is reported that if the daily energy-saving lamps are used for example, energy-saving lamps are 4/5 more energy-saving than incandescent lamps, while LED is 1/4 more energy-saving than energy-saving lamps. In automobiles, the energy consumption of LED components is only 1/20 of that of halogen lamps for the same daytime running lights.
