LED lighting into the automotive field into the mainstream of automotive lighting development

Transportation LED lighting has become as an important application of the lighting market, at present, LED has been applied to the inside and outside the vehicle, especially in the automotive interior lighting, color LED applications has been very mature, for example, instrument panel, backlight lighting switch, auto reading lamp or head up display system, or car in the "on-demand color selection" (Color-on-Demand) function, let the car manufacturers can use their own unique color recognition, apart from other competitors, or the use of color to distinguish different series of products.

Seven advantages LED lights

The advantages of LED lamp and incandescent lamp is significant. First, long life, generally up to tens of thousands or even one hundred thousand hours. Some people think that if the future of automotive lighting using LED, the entire vehicle use time without replacement lamps. Two is very energy-saving, more than half of the incandescent lamp at least the same brightness. Three light quality is high, basically no radiation, is a "green" light source. Four is a simple structure of LED, surrounded by a transparent epoxy resin seal, good seismic performance. Five is not a hot start time, light response speed (nanosecond), suitable for the use of fast moving objects. Six is applicable voltage between 6-12 volts, can be applied to the car. Seven is a small footprint LED, the designer can change the lighting mode, so that the diversification of car styling. Car manufacturers favor LED, is entirely the merits of the LED itself in the future of the automotive industry decided.

The development of LED lights

Automobile external application in development, brake lights, taillights and turn lights, down lights, high brake lamp have been using LED, the brake lights, tail lights and brake lights with larger scale. As the vehicle headlight, due to the high power LED, by LED technology and control performance, especially in optical, electronic control, thermal management field also has some difficulties, it will take three to five years of popularity, the industry is also only in some high-end luxury models began to be used. In addition to the current widely used high lights, brake lights, turn lights, down lights will also be domestic LED auto lamps large-scale application of LED.2010 years of market size may be more than 1 billion yuan, may form annual output value of 3 billion yuan within 5 years. According to the 2010LED special report released in 2009, is expected by 2013 about 95% of new cars in the world will be one or more of the tail lights in the use of iSuppli LED.

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, a significant decline in the price of LED, increasing luminous efficiency and cooling technology is the main focus of future development of LED automotive lamps. Although there are still some problems need to be solved, but LED has the advantages of small size, high shock resistance, energy saving, long life and other advantages, while giving the designer a broader design space, these are elements of increased LED in the car inside and outside the application. With the continuous improvement of product technology, product types continue to expand, the future of the car will be safe and intelligent direction. Automotive lighting will also be intelligent lighting system, the art of lighting products, green car products, such as the direction of development.

LED automotive lighting applications market sales each year to maintain 10% growth rate, but the proportion of domestic LED auto lamps is not high. LED relatively large amount of vehicles in the middle and high end of the automotive business, and these car companies will generally be limited to the LED brand, domestic LED companies are more difficult to enter its supply chain.

In addition domestic LED and the international famous brands, there may be uniformity in the aspects of life and the sorting problem some more, at the same time, the car lighting has a strict market regulation, the threshold is relatively high, the car as a luxury consumer goods, sales of the back is one of the customer, any quality problems will due to complaints of domestic LED have no opportunity to experience this after a long-term large-scale market, it is difficult to achieve the car with LED standard. The car lamp is very professional in the field, to do LED auto lamps, both auto lamps enterprises or LED enterprises, it will be very difficult, need to automobile enterprises and LED enterprises to fully communicate, especially in the development of LED automotive headlamp on.
