Transportation lighting has become an important application market for LEDs as an illumination source. At present, LED has been applied to the interior and exterior of automobiles, especially in automotive interior lighting. The application of color LEDs is already very mature, such as for dashboards, backlight switches, and automobiles. Reading lights or head-up display systems, or the use of the "Color-on-Demand" feature in cars, allows car manufacturers to differentiate themselves from other competitors by using their own distinctive colors. Or use color to distinguish different series of products.
The seven advantages of LED Lights are: LED lights and incandescent lights have significant advantages. The first is long life, which can reach tens of thousands or even 100,000 hours. Some people think that if the future car lights use LED, the entire car does not have to replace the lamp during its service life. The second is very energy-saving, which is at least half of electricity saving than an incandescent lamp of the same brightness. The third is high light quality, basically no radiation, which is a "green" light source. Fourth, the LED's structure is simple, surrounded by a transparent epoxy resin seal, good seismic performance. Fifth, there is no need for hot start time, and the lighting response speed is fast (in nanoseconds), which is suitable for objects with fast moving speed. Sixth, the applicable voltage is between 6-12 volts, which can be applied to automobiles. Seventh, the small footprint of the LED allows the designer to change the lighting mode at will, making the car shape more diverse. Automobile manufacturers favor LED, which is entirely determined by the merits of LED itself in the future automobile industry.
Development of LED headlights External applications of the automobile are also developing continuously. Brake lights, taillights, turn signals, reversing lights, high-position brake lights, etc. have all been applied to LEDs. Among them, brake lights, taillights, and high-level brake lights have been applied. Larger. As the vehicle headlamp lighting, due to the need for high-power LED, subject to technology and LED cost-effective constraints, especially in the optical, electronic control, thermal management, there are still some difficulties, the popularization also takes three to five years, the industry It is only applied on some luxury high-end models. In addition to the taillights, high-position brake lights, etc., which are currently used more generally, LED lights will be used in large-scale applications for turn signals and reversing lights in the future. In 2010, the market size of domestic LED auto lamps may exceed 1 billion yuan, and the output value of 3 billion yuan per year may be formed within 5 years. According to iSuppli's “2010 LED Special Report†released in 2009, it is estimated that by 2013, approximately 95% of new cars worldwide will use LEDs in one or more taillights.
There is still a big difference between the prices of LED lights and conventional lamps. For example, a mid-to-high-end sedan and incandescent lamp set cost 120 yuan per set, while the LED combination rear lamp requires 210 yuan per set. Therefore, LED prices have fallen sharply, luminous efficiency has been continuously improved, and heat-dissipation technology has been increasingly improved. This is the main focus of the development of LED automotive lamps in the future. Although there are still some problems that need to be solved, LEDs have the advantages of small size, vibration resistance, energy saving, long life, etc., and at the same time give the designer a broader design space. These are all factors that increase the application of LEDs inside and outside the vehicle. With the continuous improvement of product technology and continuous expansion of product categories, the future of automobiles will develop toward security and intelligence. Automotive lighting will also develop into smart lighting systems, artistic car light products, and green car light products.
The sales of LED automotive lighting application market maintain an annual growth rate of about 10%, but the proportion of domestic LED automotive lamps is not high. The models with large LED usage are concentrated in mid-to-high-end auto companies. These auto companies generally have limited LED brands and it is difficult for domestic LED companies to enter their supply chains.
In addition, compared with international famous big brands, domestic LED may have more problems in terms of lifespan and homogeneity of sorting. At the same time, auto lamps themselves have strict market supervision, high threshold, and automobiles as luxury consumer goods. Right for one-on-one customers, any quality problems will cause complaints, domestic LED does not have the opportunity to go through this market long-term large-scale experience, it is difficult to achieve automotive LED standards. Automotive lighting is a very professional field. To make a LED car lamp, whether it is a car lighting company or an LED company, it will be difficult to go it alone. It needs a car lighting company to fully communicate with the LED company, especially before the LED car. Lighting development.
