An high cost of LED application in automobile headlight to be promoted

LED entry vehicle market has been for many years, but due to lack of brightness and cost reasons, has not been generally accepted market. Compared to foreign countries, the domestic automotive applications LED to lag for a few years, is still in its infancy, is mainly used in the high-end car market, while abroad, especially the Japanese car has been widely used in LED.

Application is started

Auto LED lamp according to the application can be divided into light lamps and decorative lamp two, light lamp applies to the meter indication lamp backlight display, before and after the turn lights, brake lights, down lights, fog lights, reading lights and other functions; decorative lamp is mainly used for automobile light color transform, car inside and outside the beautification effect. In recent years, with the resolution of some vehicle LED brightness problems and the decline of the cost, its application has increased.

Shanghai Koito automotive lamp Co Ltd electronic technology department chief Jiang Chun introduction: "side turn lamp, high brake lights, brake lights, tail lights, has been in the domestic high-end cars used widely. In the field of LED lights, Koito company focused on the combined rear lamp, rearview mirror side steering lamp, high brake lights, for Cadillac series, Buick Royaum, TOYOTA MARKX successfully developed LED products; now gradually LED will be used in car lighting etc.." Hella Lighting Technology Co., Changchun R & D Center Engineer Jin Ronghao introduced: "the number of LED application of different grades of car is not the same as the difference of the same brand of different application models of LED are very large. At present, LED is mainly used in Hella lighting signal lamp, combined rear lamp (except the reversing light outside, because of the higher costs), and because the brightness and the curve of the problem is not solved well, the application front headlights LED is still in the development stage. The LED lamp is mainly supplied to domestic Hella German cars, all of the application of LED combined rear lamp in the coming one or two years, golf, Bora, Passat will plan by Hella supporting lights."

Jin Ronghao said, "the current domestic LED lamp Market in the initial stage, the current to the lamps, the Jetta Bora Hella month for 10 thousand sets of application of LED, the average price of each set of matching lamps LED in 40 yuan. With the application of LED in the future to increase the number of types of lights and the number of LED lights each increase, the car LED market size will continue to increase, is expected in 2008, the domestic car LED will be a lot of applications." Although the luminous flux of headlamp used in all kinds of lights in the market for the most amount of car use, the potential market is huge, but due to the application requirements of high technology, and the development cycle is longer, the expected products of light commercial LED before may be around 2008. Olwe consulting believes that the current domestic car market demand for LED scale is less than 1 hundred million.

Domestic enterprises

LED field in the car, there is no domestic production enterprises, only two or three photovoltaic industry base doing research in this area. There are two main bottlenecks in the development of domestic automotive LED Market: first of all, due to the lack of independent brands in our country, and mainly in the low-end cars, the demand for LED is very limited. And occupy the domestic car market share of foreign brands, its LED supplier selection and certification is very harsh, domestic LED enterprises is difficult to enter its supply chain. 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. Secondly, the domestic LED to low LED products, it is difficult to achieve the LED standard. Jin Ronghao said, only a breakthrough in product patent technology, is likely to occupy a space for one person in the LED related applications on the market, the current domestic enterprises it is difficult to purchase foreign cars with LED production line equipment, which is mainly to the chip production equipment do not buy foreign technical barriers seriously set. At present, the global major manufacturers for Agilent LED chip (Angilent), OSRAM of Germany, Japan and the United States Nichia Cree these companies. But because the LED lamp is a major trend in the development of the lamp, and lighting a huge market demand in the fast development of LED LED chip industry, in order to adapt to the market demand in the next few years, the domestic LED chip quality and production scale will be significantly improved.
