LED car market opportunities are good. Looking at the development prospects of automotive lighting applications, Nichia has been fully attacked by direct mounting chips (DMC), flip-chip LEDs and laser diode (LD) technology, which is expected to become a new source of revenue growth.
The technical director of the second division of Nichia Chemical Co., Ltd. said that the market for automotive LED headlamps is not yet clear, and it is expected that the future will develop more rapidly, and the laser diode will become more and more popular after the headlights. He pointed out that the laser diode is characterized by a much higher brightness than conventional LEDs and a longer illumination distance, so the laser diode has great application potential in the automotive field.

However, in the automotive field, not only sufficient brightness and illumination distance are required, but also high stability and stability are required. Sakamoto said that last year, the US car airbag failure caused great damage. Therefore, the requirements of auto parts for auto parts are higher than in the past, and the requirements for LED lights have also increased. This will be a good development opportunity for Nichia.
Nichia Chemicals’s law-enforcement minister, Akutagawa’s success, added that Japan’s investment in the laser field began in 2005 and it has also obtained a lot of patents. This technology is more difficult than white light with blue LEDs. Higher, there are only a handful of manufacturers in the world that can achieve high-quality blue laser diodes, and Nichia is one of them.
Akutagawa said that the biggest challenge for LED lights entering the automotive market is the reliability requirements of the car manufacturer. Generally, the lamps usually only need to be guaranteed for one year, but the lamps usually need to guarantee the life of the products for five years, so the product quality requirements are completely different. He stressed that the Japanese Lexus LS600H car is the first to adopt Nichia LED headlights. In the past seven years of cooperation, there has been no problem with any consumers having broken lights. However, is it necessary to use laser diodes for the lights? Akutaghachi believes that the main reason for the use of laser diode technology by the car factory comes from the speed limit problem in Germany. If the speed of the moving car is as high as 200 kilometers or more, You must see more than 600 meters, and the general LED light is only 100 to 200 meters away. To reach 600 meters, you need to use laser diode technology to achieve it. The reason why the diode is used as a lamp.
