Development status of automotive LED

Currently on the market, the main source of automotive lamp is halogen, xenon and LED. Halogen lamps are the most common, and now more than 60% of the market new cars are using halogen headlamps, the advantage of low manufacturing and maintenance costs, easy to replace, and the shortcomings are obvious, the brightness is not enough. As was the "high-level product", xenon headlamps once all the rage, high brightness, long distance is its biggest advantage, once the owners as essential configuration.

However, xenon headlamps as a transitional product, the disadvantage is also very obvious: start delay, start instant strong current impact and other issues have been plagued by owners. At the same time, xenon headlights in the rain and fog weather penetration is not ideal, especially in fog, the driver's eyes is basically a vast expanse of white.

With the development of industrial technology, LED lighting has gradually become the future trend, now in the field of home lighting, LED lighting has become the mainstream, the reason is very simple, LED light source with a smaller power in exchange for better brightness, Better lighting at the same time reduce the energy consumption, and have a longer life, it can be said that multiple purposes.

In the field of automotive lighting, LED headlamps are still part of the "high-end" products, more common in some luxury brand models, generally less than 20 million cars with little LED headlamps, even if there is basically the top with Models will be equipped with, but not all LED headlamps, only the commonly used low beam light source replaced with LED light source. And if further down to see, in the 15 million range, then almost no use of a LED headlamps vehicles are not, the high tax rate of imported cars do not have to say, whether it is a joint venture model or to win the configuration of the Chinese brand models , It is difficult to find one to. But this time, Mustang T80 broke the situation.

Well, when it comes to car LED headlamps, it is necessary to mention the famous "lamp factory" - Audi. In 2008, Audi first used in the A4 LED daytime running lights, first of all to open the automotive LED era. After many manufacturers have begun to follow up, one after another with LED daytime running lights. European legislation, in order to drive safety, all in the sale of models must be equipped with LED daytime running lights. However, in a period of time, all manufacturers only stay in the LED daytime running lights this step. Until 2010, the Audi A8 and the second generation Mercedes-Benz CLS launch, the real significance of the LED headlamps appeared in people's attention.

Then the Audi A8, with a pair of Matrix LED headlamps fiercely stunning a return to not only feel stronger than the Mercedes-Benz CLS, Audi also won the "lamp factory" name. The matrix LED headlamps of the Audi A8 are made up of LED lamp beads, laser range finder and brightness sensor. During the night driving process, the matrix LED headlamps will always use the high beam lighting. Once the light source sensor Measured to have to car, it will automatically adjust or turn off the light group within the number of LED lamp beads, so that the front of the vehicle Buzhi Yu interference by strong light to ensure traffic safety.
