What we call LED lighting products generally include in-vehicle LED lighting and off-board LED lighting. Among them, the interior lighting includes dashboard lights, reading lights, etc. The exterior lighting mainly includes automobile headlights, turn signals, brake lights, and running lights.
It is reported that the application threshold of LED lighting for vehicles at this stage is still very high. In the international arena, LED lights are basically applied to the high-end market, such as Mercedes-Benz, BMW, Toyota, Ford and other high-end cars have used LED lights. The manufacturers that supply LED lights to European high-end car manufacturers are basically foreign companies. This market is basically monopolized by foreign countries. It is difficult for domestic LED companies to cut into their original lamp supply chain, LED companies in Taiwan and mainland China. More is to compete for the after-sales maintenance market.
Despite this, most of the industry is still optimistic about the future prospects of LED automotive lighting. Its profit is higher than other application products. It is reported that the average gross profit of LED automotive lighting is above 30%, and the automotive lighting market has been maintaining a certain speed.
Some insiders predict that the global LED automotive lighting market will have a compound growth rate of 9% in 2014-2018. In 2018, the global LED automotive lighting market will reach 2.5 billion US dollars. This is a good news for LED companies that are intensifying their competition and thinning their overall profits. Therefore, there will be more LED companies to join this segment to work hard.
LED headlight performance outstanding
At the moment of rapid development of society, people's living standards have improved compared with the past. All kinds of cars have gradually become an indispensable means of transportation for people's daily life, and having a high-class car is also one of the pursuits of many people. The configuration of a car largely represents the quality and grade of the car, and the car light is like the "eye" of a car. The quality of the car not only affects the appearance of a car, but also affects the appearance of a car. quality.
Today, as the mainstream of the lights, there are mainly three types of lamps, halogen lamps, xenon lamps and LED lamps.
The first type of halogen lamp is a new generation of incandescent lamp, which is a tungsten lamp filled with a halogen element or a halide such as bromine iodine. It was used in cars as early as 1960, and it was mainly used for car headlights. Halogen lamps are widely used in automobiles mainly because of their low cost. However, the xenon lamp and the LED lamp whose brightness is not comparable to the same power, the light output efficiency is low, and the irradiation distance is short.
The second type of xenon lamp, referred to as HID in English, is a gas discharge lamp that needs to be used with a ballast. It has been used in cars since the 1990s, and its light intensity is three times higher than that of ordinary halogen bulbs, and its energy consumption is 2/3 of that of halogen lamps. It has a wider range of illumination than halogen lamps, and emits almost the same color and daylight, and has a good visual comfort. However, the reaction speed of the lights is still not as good as the LED lights.
The third type of LED light was only applied to the lights in 1985. Compared with the first two types of lights, although it is later in development time, it has an advantage in performance. As we all know, LED energy saving and environmental protection, energy consumption is only 1/20 of the halogen lamp. Moreover, the life is long. In terms of service life, the halogen lamp is generally 600 hours, the xenon lamp is generally 3000 hours, and the LED lamp can reach 30,000 hours. Moreover, the reaction speed is fast, and it takes only a few microseconds to light up, thereby improving the driving safety factor.
In addition, the LED light components are small, which can bring more space for the design of the lamp. Its environmental adaptability is also good, unlike the xenon lamp needs to be used with the ballast, and it is shock and shock resistant. It is superior to xenon lamps in color rendering, closer to daylight, and has a wider range of illumination.
According to Zheng Minhui, deputy general manager of Taiwan Hongkai Optoelectronics (hereinafter referred to as “Hongkai Optoelectronicsâ€), the number of LED lights used in a car is between 200 and 500.
As early as the 1990s, in the high-end automobile manufacturing, LED lamps have the tendency to replace xenon lamps as high-end automotive lamps.
At present, in the high-end automotive lighting market, such as Mercedes-Benz, BMW, Toyota, Ford, Volkswagen, etc., the launch of a new car with a variety of LED lights to attract consumers.
