LED headlight headlight energy saving will become the mainstream of life

The application of LED technology in automobile is more and more widely, has to enter the car taillight headlight category.

Audi latest models who may have been found in the past few years continuously in the brake light used LED (light emitting diode) began to appear in the car headlights in. In fact, the role of LED lighting technology is not only the decoration, it will be the future direction of the development of automotive lighting.

Potential, lighting effect still needs to be improved

Solution word: light emitting diode is composed of the electric energy can be directly converted into light energy made of crystal semiconductor, gallium arsenide and gallium phosphide is the basic material.

Automotive Engineers and designers are interested in the light emitting diode, compared with traditional incandescent lamps, LED made headlights not only the lighting effect is high, and low energy consumption. In the case of the same illumination, the demand of high power led to the power demand is half of the halogen lamp. Although in the current circumstances, LED can not reach the energy efficiency of xenon headlamps, but this technology still has great potential for development. Between 2004 and 2006, the average performance of LED increased by nearly two times. Professionals expect that by 2008, LED will be 3 times higher than in 2004. At the same time, the focus of automotive experts focus on white multi chip light-emitting diodes, they expect to 2009 or in 2010, the light-emitting diode can produce the same power as the current xenon lamp. In addition to the festival, LED also has a lot of other materials are difficult to match the advantages, such as its life of up to 10000 hours, the basic and the normal service life of a car.

LED lighting array technology evolution

Solution: in the automotive industry, the application of LED LED technology based on array -- many high power light emitting diode on a circuit board, which is called the array. This combination has a powerful function, each of the light-emitting diodes on the circuit board can be independently controlled, so that the distribution of light can be arranged according to the actual requirements.

In the long run, all you can think of the lighting function can be achieved by the control of light emitting diode to achieve, such as dynamic light adjusting distance and angle adjusting of fog. In addition, such as highway mode, active lighting function or turn lighting function can be controlled by a single or multiple light-emitting diodes to adjust. With this technology, similar to the Mercedes Benz owned headlamps village mode, highway mode can be completed by a simple program settings. It can be predicted that the future application of intelligent lighting systems in the mobile components may be fully replaced by LED products.
