LED car headlights hidden business opportunities, but the heat problem has become a technical bottleneck

Led with advantages of small volume, long life, low power consumption and fast response, has become a new generation of light source has attracted much attention; but most of the existing LED light source technology application in the interior of the vehicle dashboard backlight, or is outside the car brake lights, lights, reversing lights direction and other parts. The headlight is limited to a single LED brightness is not enough, the price is too high, the world is still in the development stage, is expected to be entered into commercial production stage 2 to 3 years. Potential business opportunities for this technology, the current China Taiwan vehicle research and Testing Center (ARTC) has developed a number of patented technology, the level of synchronization with the international.

ARTC R & D Project Manager Liao Xuelong said: "with the traditional incandescent lamp and fluorescent lamp with LED, in addition to prolong the service life of 10 times, the power consumption is only 10%, the high reaction rate in high frequency operation, environmental protection and other advantages, can be used as planar packaging technology, design a high degree, for the whole automobile industry LED, light not only will auto parts supply chain brings about great change, the future car design will therefore have more possibilities. "There are many manufacturers in Taiwan China R & D LED lighting technology, such as billion light (Everlight), USI (USI), tiweixi (TYC), Tai Po (DEPO), Dayi (Ta Yih), including LED components factory, supply and light industry.

Liao Xuelong said, Taiwan Chinese lamp manufacturers because of mold skilled, high product quality, fast delivery, has established a good reputation in the international market; but because of the future LED headlights will be active to form development, need collocation electronic sensing and control technology co design, will not have the relevant ability Taiwan area China manufacturers is a major challenge. According to the latest active steering type "road car headlight system (AFS), the ARTC has successfully developed vehicle lamp technology for white LED, other patents include projection / reflection type LED lamp, adjustable lighting color LED lamp, LED headlamp for miniature LED group. Lighting module, TIR lens, LED headlamps, car headlights and LED over temperature protection device technology.

Liao Xuelong pointed out: "LED lights must have high reliability at -40 DEG ~125 DEG C high power, high efficiency and working temperature, and the optical and electrical parameters must be stable and consistent, the light intensity attenuation can not exceed 20%; one part of the most difficult to overcome the problem of heat dissipation. "As long as the LED grains meet high temperature, the luminous efficiency will decay or damage, the recommended operating temperature is below 80 DEG C, so in the application, how to use efficient cooling technology, let LED lights to work, become the key design; ARTC has a LED headlight cooling system preliminary research results, but not yet completed with real vehicle test, and it is also the center of spindle technology development this year one of the.

ARTC and combination of production, learning and research professionals from all walks of life to set up advanced lighting systems in 2004 (ALS) research and development alliance, the light control and sensing system, plastic material and process technology, and optical design analysis, vision for research and development projects, to be combined with more light R & D resources. ARTC is working on the standard development of vehicle light product validation, hoping to help manufacturers and foreign car factory in line with market opportunities.
