(Summary description) The advantages of LED light source are obvious LED components have the huge advantages of being small in size, compact and easy to arrange and design, leaving a broad space for car manufacturers in the design of car appearance, breaking the constraints of the lighting system on modeling innovation in the past, and meeting the needs of car appearance modeling. my country's own brands have great interest in this aspect, which also brings business opportunities to the domestic LED lamp industry. Due to the fast lighting speed of LED lights, it can reflect the vehicle and road conditions in real time, leaving the driver with a longer judgment time. According to the measured speed of 100 kilometers per hour, the rear car can shorten the braking distance by 7.5 meters. Effectively preventing rear-end collisions and reducing automobile safety accidents has positive significance for improving the active safety of automobiles. In addition, LEDs have controllability, such as light type, illumination range, and brightness can be adjusted linearly, while traditional xenon lamps cannot. In recent years, LED technology has continued to develop, technical shortcomings have been overcome, and LED lights have become more and more intelligent. For example, the LED headlights of some models are equipped with oncoming vehicle detection radars and control computers. Even if the driver turns on the high beams for a long time, it will automatically reduce the light pattern of the lights or even reduce the brightness when encountering an oncoming vehicle. Energy saving and environmental protection is another significant advantage of LED lights. According to the plan of the Ministry of Industry and Information Technology, by the end of 2015, automotive lighting needs to complete the carbon dioxide emission reduction target. Because LED lights are cold light sources, they have the advantages of low power consumption and long life. The power consumption is only 1/10 of that of traditional lights, which can better save fuel consumption. It is reported that if the daily energy-saving lamps are used as an example, energy-saving lamps are 4/5 energy-saving than incandescent lamps, and LED lamps are 1/4 energy-saving than energy-saving lamps. In a car, for the same daytime running lights, the energy consumption of LED components is only 1/20 of that of halogen lamps. The German three giants lead sports car light technology The LED automotive lighting market is divided into interior lighting applications and exterior lighting applications. In the application of automotive interior lights, LEDs are widely used because of their rich colors, such as dashboards. At present, there are very few cars that use small light bulbs for dashboards. In the next few years, all car dashboards should use LED lights. In addition to the dashboard, common LED interior lights include dome lights, instrument lights, door lights, reading lights, step lights, etc. Common exterior lights include headlights, brake lights, fog lights, reversing lights, turn signals, and daytime running lights. At present, many models of brake lights, tail lights, turn signals, reversing lights, high-mounted brake lights, etc. have already applied LED. As for the application of LED headlights, Audi, BMW and Mercedes-Benz are currently leading the way. In the automotive circle, Audi and BMW are the two who can play with lights the most. BMW's angel eyes and continuous light strip taillights have become classics, while Audi has excelled in the design of the lights. As lighting experts, these two companies have also taken the lead in applying LED light sources to many of their models. Currently, the BMW 5 Series can be equipped with LED headlights, some models of the BMW X6 are equipped with LED headlights, and the Audi R8 and A8 are equipped with LED headlights as standard. Most models also come standard with LED headlights. In addition, although Mercedes-Benz does not have the other two to play, it is very willing to pay for the lights. The new E-class is equipped with LED headlights as standard, not to mention the S-class. In addition, the new generation Mondeo, new generation X-Trail, Honda Accord, Lingpai and Jade all have models equipped with LED headlights. Obstructed by high cost, LED still cannot fully replace halogen lamps and xenon lamps in the next 3-5 years. Looking back at the development of car lights in the past, it took nearly 20 years for halogen lights to mature slowly. From the advantages of LED lights, LED lights will inevitably become the development trend of lights in the future, but it will take some time to transition. In the future, the price of LED lights will drop steadily, and they will be more widely used in the automotive field, and LED lights will also become safer and more intelligent.
