Car energy-saving lamps began to play LED lighting ideas

As a new green lighting source, each field of semiconductor lighting is gradually into people's daily life. The transportation of LED lighting has become as an important application of the lighting market, in the 2010 Shanghai international new light & New Energy Lighting Forum "new light source and transportation lighting change special summit, from the field of semiconductor lighting and guest LED application enterprises around the application of semiconductor lighting in the tunnel lighting, rail transportation, car lighting the lamp and other aspects of a lively discussion, and good prospects for the development of the market has become the focus of.

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 the car adopts' on-demand 'color selection (Color-on-Demand) function, let the car the manufacturer can use their own unique color recognition, apart from other competitors, or the use of color to distinguish different series of products. Zhong Jiecong, director of the Asia Pacific market for OSRAM semiconductor Asia ltd..

Auto external application in the unceasing development, Shanghai Koito automotive lamp Department of electronic technology limited company secretary Zhu Minghua introduced, brake lights, taillights and turn lights, down lights, high brake lamp have been using LED, the brake lights, tail lights and brake lights used larger. 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.

Zhu Minghua believes that in addition to the current application of the more common taillights, high brake lights, etc., the future direction of the lights, reversing lights will be large-scale application of LED. 2010 domestic LED automotive lighting market size may be more than 1 billion yuan, the annual output value of $3 billion may be formed within 5 yuan. Zhong Jiecong said, according to the iSuppli in 2009 released the 2010LED special report, is expected by the year 2013 about 95% of new cars in the world will be used in one or more taillights lighting LED.

At present, the sales volume of LED auto lamps market is about 10%, but the proportion of domestic LED auto lamps is not high. Zhu Minghua said that the use of a relatively large amount of LED models are concentrated in the high-end automotive companies, 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 to domestic and international well-known brands compared to LED, may exist in the aspects of life and the uniformity of 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 to the back of a customer, any quality problems will lead to complaints LED, domestic no chance after a long-term large-scale experience of this 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. Zhu Minghua said.

And for the development of LED auto lamps, Zhong Jiecong believes that the car taillights, high brake lights, turn lights, side lights, beam lights and high beam car application require different lumen. In fact, lumen values depend on the system efficiency of the optical components used. As a result, the LED needs to be further developed as a whole, such as a more mature thermal management, an optimized high resolution optical element, and an electronic device used to connect an automotive electronic system.

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.
