LED car lamps in the automotive application more and more widely, before only the luxury car, and now gradually in the middle and advanced vehicles to promote. Compared with the traditional light bulb, LED lamp has long service life, better lighting effect and more beautiful appearance, but the LED lamp a component damage will be replaced overall, resulting in a higher cost, generally 1000 to 2000 yuan. Therefore, consumers in the choice of models to take into account their economic ability, cautious purchase.
At present, led car lights in the brake lights, taillights, steering lights, reversing lights, high brake lights and other lamp positions are applied. Its characteristics are also very obvious. First of all, LED lights than the same brightness of the incandescent lamp to save more than 60%. Second, the structure is simple, the light-emitting body is a semiconductor (solid), surrounded by transparent epoxy resin seals, good seismic performance. Third: Long service life, the use of 10,000 hours of light decay is only 50%, the General Service life can reach more than tens of thousands of hours. IV: Does not contain harmful metal mercury, basically no radiation. But the biggest factor affecting the lighting efficiency and life of LED vehicles is the temperature, because the car headlights in use, the heat emitted is very large, resulting in the surrounding temperature is very high, and cooling is not very fast. and led to the car to make the normal operating temperature of the lamp is under 60 ℃, when the temperature exceeds 60 ℃, the LED work appears to be less stable. Therefore, if the car headlights in the ambient temperature beyond a certain temperature, LED is very easy to burn off, and sometimes even the base of the LED lamp will be directly dissolved. For most of the vehicles using LED lights, if the diode damage seriously more need to directly replace the assembly. At present, the price of the replacement of a set of LED lights between 1000 yuan to 2000 yuan, is the traditional lamp several times.
