The output value of LED auto lamps in China will reach 1 billion

In recent years famous brands such as BMW, Ford, Honda cars, TOYOTA, Mercedes, Audi, Lexus and spare no effort to explore new selling point, eager to launch all kinds of new car to attract customers, so as to develop their fascinating headlights style a riot of colours. LED lamps as light sources for the fourth generation car, has for many car manufacturers to make good use of beautiful Huan Macmillan headlights style. LED lamp has the advantages of no delay, energy saving, long life, low heat, earthquake resistance, high color purity and so on. It has become an inevitable product of tungsten filament lamp and halogen lamp. Vehicle LED lamp is divided into two major categories of lamp decoration and function. Decorative lights are mainly used in the car inside and outside landscaping, the current multi control circuit to achieve the effect of colorful decoration. Function LED lamp is the most suitable for digital meter assembly indicator lamp backlight display, front and rear lights, brake lights, contour lights, reversing lights, fog lights, reading lights. The use of LED basic requirements and general use of similar to LED, but the angle of the LED, color, brightness, discrete voltage value, light, heat, ultraviolet proof and high reliability requirements. LED headlamp is currently in the development stage, the Japanese company has small sample lamp exhibition, the famous German brand center to Hella source with optical fiber directional light guide design originality, also introduced the concept of the product, but not yet in production. The main reason for the single LED element flux is not enough (the white LED market is only the introduction of conventional current LED 2.6Lm), and the large size wafer package heat and light effect is still a major problem, with the progress of continuing popularity and material research of crystal growth technology, the industry is expected in the next 5 years will be commodity market, and the technology is expected in the next three years to launch its own front headlights concept product. Standard and design of LED lamp

At present in the world both at home and abroad are based on the traditional tungsten filament lamp, halogen lamp as the standard general requirements, production inspection standards are not independent of the LED lamp lighting. So the current LED lamp manufacturing enterprises producing lamp assembly design and production is still the basis of GB and SAE standards, to make the LED lamp light source light distribution and configuration in accordance with the traditional standard, LED light source must be designed into three-dimensional arrays by adjusting the LED light direction to reach the light distribution, car lamp design is a new technology. Because of the monochromatic nature of the LED light source, it is possible to use different LED elements with different wavelengths to design different steering lamps, brake lights, reversing lights, etc.. No more to filter light transmittance increase (filter using transparent polycarbonate or organic glass cover of the light transmission rate of 92 - 95%%), so as to improve the utilization rate of light.

Also used LED element LED lamp in order to meet the requirements of the traditional light distribution standard, point selection is very important, the right light angle means that the LED can use the correct number of components to achieve economic and practical purposes. Due to the LED side astigmatism less, lamp reflector cup role than the traditional light bulb is not obvious, so the distribution of LED light source array to be dispersed, and the traditional light bulb is the opposite, the purpose of the dispersion is also more in line with the visual habits. Heat dissipation design is a very important part in the design of LED lamps, whether the heat dissipation is good determines whether the lamp life can reach the set value.

LED lamp is the trend of development

LED lamp used in the domestic car on the rate of less than 1%%, and the LED lamp use rate of 30%% in New Zealand, and other countries have a large gap compared. LED lamps in the development of the Chinese market is currently the main resistance is the cost problem. LED chip production technology is difficult, the threshold is high, the crystal process of temperature, humidity, power supply, dust removal requirements are very strict, the initial need to invest heavily in building factories. At present, the main origin of LED chips in Taiwan, China, occupy the LED market of 47%%, while in mainland China LED plant for resin packaging processing, the chip needs a large number of imports, is the reason of high cost. The second is the manufacturers and consumers in the domestic automobile industry awareness of LED lamp is not enough, with LED lights with the traditional lamp cost comparison of habitual thinking is influencing the development of light industry LED, two is contributed to the low quality with low price some type of processing enterprise products into the market of LED lamp.

LED lamp is a major trend in the development of the lights, lights and lighting is to stimulate the development of LED chip industry with common LED huge demand, quality and yield of LED chips will be the next 5 years have significantly improved in order to adapt to this demand.

LED lamps will reach 1 billion yuan output value of China's first LED lamp is high brake lights of Santana 2000, jointly developed by the Shanghai Automobile Electronic Engineering Center and Shanghai Koito lamp Co. Ltd, and put into operation and in 2000 by the Shanghai Volkswagen Company certification, the annual output 200 thousand.

A few years ago, LED lamp market expansion is very slow, but the trend has accelerated since 2002. It is expected that there will be a rapid development in the past two years, and in each car before the combination of lights, rear lights in the group is expected to have 1 - 2 lights (such as rear brake lights, rear steering lights) using LED light source.

In the next 5 years China's LED lights will have a large-scale development, will form an annual output value of 1 billion yuan in recent years, 5 years after the formation of the annual output value of 3 billion yuan.
