Automotive LED prospect light billion light research and development strength in the industry

LED industry competition is fierce, manufacturers have turned to niche applications, of which automotive LED is a small number of stable price blue ocean market. Global LED photoelectric industry leader billion light electronics, in recent years, also actively layout of the automotive market, in addition to creating a car products exclusive Miaoli new factory, in April 2017 Taiwan auto parts exhibition, also showed the exterior, interior, ADAS advanced driver assistance system and other latest LED products. LEDinside interviewed Mr. Chen Jiahong, project manager of Yilang Automotive Product Division, to bring the industry more about the technological development trend of automotive LED, as well as Yilang's layout and efforts in this industry.

The interior starts to apply mature future focus on situational light source

        Manager Chen Jiahong said that Yiguang has cultivated the automotive LED market for 13 years, and can now provide customers with a full range of product applications. The earliest 100 million light from the automotive interior LED cut, which instrument/audio/air conditioning/central control switch development has been very mature. With the increase of consumers' demand for visual experience and in-car entertainment enjoyment, the automotive market has changed to the design of large-size screens in instruments and sound systems in the past two years. In 2017, the automotive interior products of Yiguang will focus on audio-visual backlighting, situational light sources and UV sterilization.

        In the video and audio backlight LED part, in response to the market's high requirements for color wide range, Yiguang can provide more than 90% of NTSC automotive LED products at this stage, so that the screen color is closer to the real primary color, and in the fierce competition in the field of context light source, Yiguang products emphasize multi-color high sulfur resistance, from single crystal, twin crystal, three crystal to four crystal are available. However, as the market gradually embraces colorful design, three-crystal RGB and four-crystal RGBW products are currently receiving the most attention.

        Chen Jiahong said that the international car manufacturers are very particular about the color of the situational light source, although RGB LED ternary colors can be mixed into white and multi-color, but the presentation of white is still unable to meet the ultimate requirements of pure white color. The 0.5W four-crystal (four-in-one RGBW) disclosed by Yilang for the first time can more truly present, diversified and natural white light, so that automakers can more flexibly use light sources to enhance the added value of cars.

       In addition, with the development of smart cars, the future car LED lighting system will also be more humane, such as IR infrared sensors to detect the human body temperature, so as to judge the mood of people and adjust the situational light source in the car. If the human body temperature is high, it may mean that the emotion is more excited, and the color of the situational light source can be automatically adjusted to a cool tone to create a comfortable and relaxed car space. However, if the body temperature is low, it will be changed to project a warm color light source with a color temperature of about 3000K to simulate a warm feeling like sunlight and boost the depressed mood.

       In the automotive interior, another advantage for the automotive UV LED, currently can provide the application of UVA LED and photocatalytic titanium dioxide (TiO2) air sterilization products, is also moving towards stronger sterilization UVC LED. This is a very attractive place for the automotive market, and it is expected to have a considerable inhibitory effect on the breeding of mold in the car.
