LED automotive lighting value exceed 1 billion

Transportation lighting has become an important application market for LED as an illumination source. In the “New Light Source and Transportation Lighting Revolution” Special Summit at the 2010 Shanghai International New Light & New Energy Lighting Forum, guests from the semiconductor lighting industry and LED related application companies Around the semiconductor lighting in the tunnel lighting, rail traffic lighting, automotive lighting and other aspects of the application of a lively discussion, and the good prospects for development in various markets has become the focus.

At present, LED has been applied to the interior and exterior of automobiles. "Especially in automotive interior lighting, the application of color LED is already very mature, such as for dashboard, backlight switch, auto reading lamp or head-up display system, etc. The "Color-on-Demand" function allows car manufacturers to differentiate themselves from other competitors by using their own distinctive colors, or by using colors to distinguish different series of products." Osram Opto Semiconductors Asia Limited, Asia-Pacific market director Zhongjie Cong said.

The external application of the car is also constantly developing. Zhu Minghua, the head of the electronic technology department of Shanghai Xiaolan Automotive Lights Co., Ltd. introduced that brake lights, taillights, steering lights, reversing lights, and high-position brake lights have all been applied to LEDs, including brake lights, Tail lights and high brake lights have a large application size. As the vehicle headlamp lighting, due to the need for high-power LED, subject to technology and LED cost-effective constraints, especially in the optical, electronic control, thermal management, there are still some difficulties, the popularization also takes three to five years, the industry It is only applied on some luxury high-end models.

Zhu Minghua believes that in addition to the currently widely used taillights, high-level brake lights, etc., the future turn signals and reversing lights will also be large-scale application of LED. In 2010, the market size of domestic LED auto lamps may exceed 1 billion yuan, which may be within 5 years. The annual output value of 3 billion yuan will be formed. Zhong Jiecong said that according to iSuppli’s “2010 LED Special Report” released in 2009, it is estimated that by the year of 2013, about 95% of new cars worldwide will use LEDs in one or more taillights.

At present, the sales of LED automotive lighting application market maintain an annual growth rate of about 10%, but the proportion of domestic LED automotive lamps is not high. Zhu Minghua said that the models with large LED usage are concentrated in mid- to high-end auto companies. These auto companies generally have limited LED brands and it is difficult for domestic LED companies to enter their supply chains. In addition, compared with international famous big brands, domestic LED may have more problems in terms of lifespan and homogeneity of sorting. At the same time, auto lamps themselves have strict market supervision, high threshold, and automobiles as luxury consumer goods. Right for one-on-one customers, any quality problems will cause complaints, domestic LED does not have the opportunity to go through this market long-term large-scale experience, it is difficult to achieve automotive LED standards. "Automobile lighting is a very professional field. To make LED automotive lighting, whether it is automotive lighting companies or LED companies, it will be difficult to go it alone. It requires automotive lighting companies to fully communicate with LED companies, especially in LED cars. The development of headlamps." Zhu Minghua said.

For the development of LED automotive lighting, Zhong Jiecong believes that different applications are required for off-vehicle applications such as rear lights, high-position brake lights, turn signals, side lights, low-beam lights, and high beam lights. In fact, the lumen value depends on the system efficiency of the optical components used. Therefore, before LEDs become standard headlamps, it is necessary to develop the entire system more deeply, such as more mature thermal management, optimized high-resolution optical components, and electronic devices for connecting automotive electronic systems.

Although there are still some problems that need to be solved, LEDs have the advantages of small size, vibration resistance, energy saving, long life, etc., and at the same time give the designer a broader design space. These are all factors that increase the application of LEDs inside and outside the vehicle. With the continuous improvement of product technology and continuous expansion of product categories, the future of automobiles will develop toward security and intelligence.
