10 years or so, LED will become the mainstream lights

Status quo and Prospect of domestic LED lamp Market

Since the end of nineteenth Century, the first car in the world. Since the birth of Carle Benz in the hands of people, always in the development of automotive lighting, especially the headlight is always focused on automotive lamps, experienced acetylene gas lighting, incandescent lamp, halogen lamp, xenon lamp, Nissan 300ZX company in 1986 the car uses 72 led brake lights as the central high marks, LED began to enter the automotive applications in the field of development, now LED headlamp has entered the public view.

In China, the 1999 Shanghai Koito automotive lamp company for the first time with the Shanghai Volkswagen Santana supporting the LED brake light. Now the domestic automotive LED signal market has been relatively mature, daytime driving lights (DRL) with white LED has also started. At present, LED is mainly used in automobile lamps, which is mainly used in medium and high grade car lights.

According to statistics, at present, our country has the ability to purchase a car for 20 million households, China is likely to become the world's third largest auto market, accounting for about 6% of global share, after the United States and japan. By 2025, the scale of China's auto market will reach the size of the U.S. auto market. China has become the fastest growing region in the world. According to statistics Chinese Automotive Industry Association, 2009 domestic lamp sales of more than 15 billion yuan, of which LED lights the market share increased year by year, to Shanghai Koito automotive lamp company as an example, the 2009 LED lamp lights all sales accounted for 11.7% of sales, is expected in 2011 car sales accounted for the proportion of LED lamp lights will reach more than 15%, and by 2015 LED lamp lights all sales accounted for the proportion of sales will reach more than 30%.

Statistics of sales Shanghai Koito automotive lamp company:

At present, in the new high-end models, LED taillights (combined rear lamp has become the mainstream). Domestic LED lamp applications will become more and more popular, and the proliferation of low-end models. The future development trend of automotive LED lamps will be high-power white light and high power white light signal, such as headlights, front fog lights, reversing lights, etc.. Overall, about 10 years, LED will become the mainstream of automotive lamps. LED lights (mainly signal lights) in the domestic market, the most high-end Japanese cars on the use of the United States, Europe and the United States with the development of high-end cars. Roewe, Chery, brilliance and other independent brand car also has application. Abroad, LED headlamps have been used in several models, but only small quantities. The domestic LED headlamps is still in development, Shanghai Koito in 2008 three Shanghai Roewe hybrid car trial installed all LED lights (including headlights). Estimated that the domestic LED headlamps really need to go to the market for more than two years.

At present the domestic car market competitors, sales of the top ten enterprises in the ocean has blood enterprises accounted for more than half of jiangshan.

In 2009, domestic sales of the top ten lights: LED in auto lighting applications besides the luminous efficiency and cost problem, because the surface shape of automotive lighting is more complex, the internal space is limited and closed, the application of high-power LED heat dissipation is a problem. At present, the thermal simulation test technology, LED light effect and heat dissipation technology are relatively weak. At present, LED lights with the traditional lamp prices have larger difference, such as a high-grade car, incandescent lamp combined rear lamp 120 yuan / sets, while LED combined rear lamp needs 210 yuan / sets. Therefore, LED prices have fallen sharply, continuously improve the luminous efficiency and heat dissipation technology improvement is the main focus of the future development of LED auto lamps, with the development of LED and gradually increase the price of low carbon economy, LED will be more and more applied in the light of.
