LED into the automotive field into the mainstream of automotive lighting development

Transportation lighting has become an important application market for LEDs as lighting sources. At present, LEDs have been applied to the interior and exterior of automobiles, especially in automotive interior lighting. The application of color LEDs is very mature, for example, for instrument panels, backlight switches, automobiles. Reading lights or head-up display systems, or the use of Color-on-Demand in the car, allows automakers to differentiate themselves from other competitors by using their own unique recognition colors, or to use Colors distinguish between different series of products.
The seven advantages of LED lights, LED lights and incandescent lamps have significant advantages. First, it has a long life span, usually tens of thousands or even 100,000 hours. Some people think that if the future car lights use LEDs, the entire car life will not need to be replaced. The second is very energy-saving, at least half of the energy saving of incandescent lamps of the same brightness. Third, the light quality is high, basically no radiation, and belongs to the green light source. Fourth, the structure of the LED is simple, and the periphery is sealed with a transparent epoxy resin, and the seismic performance is good. Fifth, there is no need for hot start time, and the light response speed is fast (nanosecond level), which is suitable for objects with fast moving speed. Sixth, the applicable voltage is between 6-12 volts, which can be applied to the car. Seventh, the LEDs occupy a small volume, and the designer can change the lamp mode at will, so that the car shape is diversified. Automotive manufacturers favor LEDs, which are entirely determined by the future of the automotive industry.
The development of LED headlights is also constantly developing. Brake lights, taillights, turn signals, reversing lights, high-position brake lights, etc. have been applied to LEDs, among which brake lights, tail lights and high-position brake lights are used. Larger. As a vehicle headlamp illumination, due to the need for high-power LEDs, it is subject to technology and LED cost-effectiveness, especially in the fields of optics, electronic control, and thermal management. It takes three to five years for the industry to become popular. It is also only available on some luxury high-end models. In addition to the currently widely used taillights, high-position brake lights, etc., future turn signals and reversing lights will also be used on a large scale. In 2010, the market size of domestic LED automotive lamps may exceed 1 billion yuan, and may form 30 per year in 5 years. The output value of 100 million yuan. According to iSuppli's 2010 LED special report released in 2009, it is estimated that by 2013, about 95 new cars worldwide will use LEDs in one or more taillights.
There is still a big difference between the price of LED lamps and traditional lamps. For example, a mid-to-high-end car, incandescent lamp combination lamp is 120 yuan/set, while LED combination lamp requires 210 yuan/set. Therefore, the LED price has dropped drastically, the luminous efficiency has been continuously improved and the heat dissipation technology has been improved. This is the main focus of the development of LED automotive lamps in the future. Although there are still some problems to be solved, LEDs have the advantages of small size, vibration resistance, energy saving, long life and the like, and at the same time give designers a broader design space, which are the elements to increase the application of LEDs in and out of the car. With the continuous improvement of product technology and the continuous expansion of product categories, the future of automobiles will develop in the direction of safety and intelligence. Automotive lighting will also be developed in the direction of intelligent lighting systems, artistic lighting products, and green lighting products.
The sales of LED automotive lighting application market will maintain a growth rate of 10 per year, but the proportion of domestic LED automotive lamps is not high. The models with relatively large LED usage are concentrated in the mid-to-high-end auto companies, and these auto companies generally have restrictions on the LED brand, and domestic LED companies are more difficult to enter their supply chain.
In addition, compared with international famous brands, domestic LEDs may have more problems in terms of life and uniformity of sorting. At the same time, the market regulation of auto lamps itself is strict, the threshold is relatively high, and automobiles are sold as luxury consumer goods. For one-to-one customers, any quality problems will cause complaints. Domestic LEDs have no chance to go through this market for a long time, and it is difficult to meet the LED standards for vehicles. Automobile lamps are very professional fields. It is necessary to do LED car lamps. Whether it is car lighting companies or LED enterprises, it is very difficult to go it alone. It is necessary for car lighting companies to fully communicate with LED companies, especially in front of LED cars. Development of the light.
