It is extensive day by day in application that LED technology is on the car, the category that has already marched from car tail lamp to the beam now.
The person paying close attention to Audi's newest style may already find, were popularizing LED (luminescent diode) that uses on the brake light constantly in the past several years Begin to appear in the car headlight. In fact, the function performed of LED car light technology is not merely ornamental, it will be the developing direction of future automobile lighting.
Potentiality is big, the lighting result waits to improve
Solve words: The luminescent diode can be changed into a crystal semiconducting compound of the light energy and made into the electric energy into directly, GaAs and gallium phosphide are its direct material.
Car engineer and designers have dense thick interests on luminescent diode, compared with traditional incandescent lamp, the headlight not merely lighting result that LED makes is high, and energy consumption is low. In case of the same illumination intensity, the demand for the electric quantity of the heavy-duty luminescent diode acts as half that is the halogenic headlights. Though in present cases, LED can not still reach the energy-conserving level of the xenon headlight, but this technology still has a huge potentiality to be exploited. Only between 2004 and 2006, the average performance of LED is on improving by nearly twice. The professional expects, by 2008, the illumination intensity of LED will be 3 times higher than 2004. And at the same time, the focus that the car expert cares about concentrate on the multi-sheet type luminescent diode of white more, they expect until 2009 or 2010, luminescent diode can produce like the present uniform power of xenon lamp. Except source saving, LED possesses the advantage different to match in excellence or beauty of a lot of other materialses too, for example its life-span is as long as 10000 hours, basically equal to normal life time of a car.
Array technology drives the lighting system to evolve
Solve words: In the automobile industry, the application of LED is based on LED array technology - --Concentrate a lot of heavy-duty luminescent diodes on a circuit board, this is the so-called array. There is strong function in this kind of association, each luminescent diode on the circuit board can be controlled independently, thus make the distribution of the light carry on the arrangement according to the actual requirement.
In the long run, all lighting functions that can expect can be realized by control on luminescent diode, such as the distance regulation of the dynamic light and regulation in the fog lamp angle. In addition the intersection of expressway and mode, the intersection of actice illumination and function or turn the intersection of lighting and function, may regulate by control singly or a plurality of luminescent diodes. After having this technology, can all set up to finish to similar to running quickly through the simple procedure by headlight rural mode, expressway mode,etc. had. Can predict, the ones that will apply to the intellectual lighting system in the future but the displacement means will probably be substituted in an all-round way by LED products.
