Even though the earlier than 1986 have LED 3rd brakes lights come out but because at that time technology level still low, 'with penetration rate is not high and into car supply chain difficulty also high lead to LED lights (Including side lights, taillights and daytime lights, etc. )The market has not received much attention; However, with the increase in LED brightness and the decline in prices, and the penetration rate of LED daytime lights in the past two years has also rapidly increased to 50, leading the rapid growth of the LED lamp market. the current penetration rate of headlights in LED lamps is only 1. About 1, it is more optimistic about the market and is expected to become the main growth momentum of the future LED lamp market. Even though the LED lighting market demand began to grow substantially, but the product price also saw a rapid decline situation, especially the general market price decline speed is very fast, various LED factories to ensure gross profit and profit performance, actively develop niche market. Although operating the LED lamp market mainly faces the problem of high difficulty in entering the automobile supply chain, if it can enter the future, it will also have the advantage of not being easy to run orders. coupled with the benefits of high unit prices and small price changes, Taiwanese LED companies such as Yiguang, guangbaoke, Lianjia and Liqing have actively developed the market. Huang Mengjiao, an IEK industry analyst, pointed out that LED lamps have the characteristics of high energy saving efficiency, high design flexibility, fast response speed, long service life, etc. it is helpful for car style, driving safety, and lowering repair costs, so more and more cars are starting to use LED light sources. Huang Mengjiao said that LED was used in car side lights and instrument panels in 2000. At present, the penetration rate of instrument panels is 84, which has entered the mature period of development. Based on driving safety considerations, countries began to legislate to use daytime running lights to drive the penetration rate of LED daytime running lights to 50, while others such as taillight penetration rate of 39 and headlights of 1. 1. Huang Mengjiao pointed out that after the commercialization of LexusLS600h headlights in 2007, the development of LED headlights market was started. However, due to the high price, it was still mainly equipped with high-end vehicles, such as BMWSeries6, Mercedes benzsclass, Audi, etc. However, the market is optimistic that the penetration rate of LED headlights is still low, which will bring greater growth momentum to the LED lamp market.
