The feasibility of vehicle LED lighting and advanced

In the car use LED lighting source started about the beginning of the twentieth century. The first to use kerosene lamps and acetylene Lamp in 1910 and started to use electric light source, has undergone the incandescent Lamp, halogen tungsten Lamp and high Intensity Discharge type gas Lamp HID (Intensity Discharge Lamp), since 1985 into the vehicle Lamp LED era. At the same time LED lamp used in Adaptive according to System before AFS (Adaptive Front Lighting System) technology appears.

At present, LED by numerous car manufacturers have to use to manufacture all light design. BMW, ford, Honda and Toyota, Mercedes and audi, waiting for a car in order to improve their brand of the overall competitiveness, have introduced a variety of LED lights with new cars to attract customers. With many other light source LED doesn't have advantages:

(1), long life, good vibration resistance. LED the service life of the theory can reach 50000 hours, the actual life can reach 20000 hours (ordinary halogen bulbs to only 150 to 500 hours or so), generally more than the life of the car itself. In addition, LED the basic structure of vulnerability in no moving parts, the seismic performance is very good.

(2) energy conservation and environmental protection. LED in low voltage small current conditions can get enough brightness, its power consumption for the same brightness of incandescent lamp only 10% ~ 20%; LED light source is not included in the harm to human health, production process and waste mercury will not cause environmental pollution.

(3) response speed. Compared with incandescent lamp, LED lamp response time has reached the dozens of ns, so that, when using LED as automobile tail light, can make the subsequent car drivers more early response to reduce traffic accidents.

(4) small volume. Small LED can make the car style of the design more freedom, diversified, and more fashion models; Compared with the traditional light source, the LED lights system installation depth can reduce 80 mm, this automobile modeling and internal parts to decorate to have the important meaning.

Now automotive industry in the world economy is still the pillar industry, and in the rapid development of the key period, it will drive the development of vehicle lamps and lanterns, for automotive applications in LED to provide broad market space.
