What are the obstacles to the development of automotive lighting in the future?

Technically, LED car lights more demanding than ordinary lighting, the need to meet the high brightness output and maintain the junction temperature is less than or equal to 120 DEG C, so that the application in the automobile lighting system cost is higher, and there is a large difference between the traditional lighting price, such as a luxury car, the price of incandescent lights combined rear lamp 120 yuan / sets, while LED combined rear lamp needs 210 yuan / sets. High cost restricts the commercial development of LED automobile lamps. The face of LED in the automotive lighting applications.

First, the production cost of LED lights is too high. LED by virtue of its energy saving, environmental protection, longevity, earthquake resistance, small size, fast response and other advantages gradually opened the car's LED process. Technically, LED car lights more demanding than ordinary lighting, the need to meet the high brightness output and maintain the junction temperature is less than or equal to 120 DEG C, so that the application in the automobile lighting system cost is higher, and there is a large difference between the traditional lighting price, such as a luxury car, the price of incandescent lights combined rear lamp 120 yuan / sets, while LED combined rear lamp needs 210 yuan / sets. High cost restricts the commercial development of LED automobile lamps.

What are the obstacles to the development of automotive lighting in the future?

In the face of the great potential of LED in the field of automotive lighting applications, the author believes that reducing the price of lamps and lanterns in the premise of ensuring the quality of products will be the focus of future development of LED automotive lamps. However, there are not many enterprises in our country, and the technical strength is not strong enough. LED lighting manufacturers in Taiwan as well as European and American manufacturers after seeing this market have also begun to enter the mainland automotive LED lighting market. Taiwan LED Lighting Companies in the last year, the wind blowing up to the automotive boom. At present, the main producing area is Taiwan, China, which occupies 47% of the LED market, while the LED plants in mainland China are mostly only in the packaging and processing of the resin.

Secondly, because of the domestic car brand is less, and mainly in the middle and low car, the demand for LED is very limited; and occupy the domestic market share of foreign brands mainly car models, the LED supplier selection and certification are very harsh, the domestic LED enterprises is difficult to enter the supply chain. Due to the high cost of LED lights, it is only used in a small number of senior cars. But with the rise of private cars with independent intellectual property rights, to launch ten or twenty new models every year even more, because the car lamp updates faster, the joint venture under the pressure of competition, the LED lamp as the market selling point and local procurement LED to reduce costs to gradually increase, which is a development opportunity for the domestic LED enterprise.

The biggest obstacle to the development of LED is the lack of core technology. The reason why automotive lighting can stand out in many LED applications is because of its large market size and high product added value.
