Automotive LED industry is in the ascendant

With the development of the automotive industry, automotive lighting is also changing with each passing day, and more and more advanced lighting technology has been more used in automotive lighting. LED is called the fourth generation of automotive light source, English name LightEmittingDiode, Chinese translation of "light emitting diode", is a solid state semiconductor device, which can directly convert electricity into light.

One of the bottlenecks that hinder LED development is detection standards and energy efficiency testing standards. LED is a very immature industry in the world. There are no standards in the world, let alone detection methods. “Semiconductor lighting technology is still at a mature stage. There is no unified testing standard in the world so far, so its market competition is relatively disorderly.” Wu Ling said, “We should first encourage corporate standards and industry standards. , and then gradually rise to national standards,

Compared with traditional light sources, LED light sources have the advantages of long life, fast response time, and low energy consumption such as halogen lamps and xenon lamps. The light emission of the LED light source is close to that of a single light, which is less affected by the voltage. The short response time, as used as a brake light source in the car, will make the driver of the rear vehicle more noticeable, which also means that the vehicle has obtained a longer braking distance.

Now, in the domestic LED is more used in outdoor displays and automotive electronics, such as the kind of large-scale display, for example, car taillights, currently 50% of the new car is used in the taillight technology LED, may later be Expand to 80%. LED lighting is currently in foreign countries, especially in Europe and the United States, the most widely promoted, but in the domestic promotion is not very full, the market has great potential.

The reason why LED lamps were originally promoted in China is because of the high price. Now, with an LED lamp, the cost of the chip accounts for more than 50%. Many LED chips use sapphire as the base, and even some use more expensive silicon carbide. All led to the high price of LED lamps. It can be seen that in the face of such a product with a broad market prospect, the primary task is to overcome technological difficulties and reduce product costs, so as to increase the market competitiveness and accelerate the speed of popularization.
