Description
【技术领域】【Technical field】
本发明涉及汽车车灯，特别是涉及一种以LED作光源的LED汽车大灯。The invention relates to a car lamp, in particular to an LED car headlight using LED as a light source.
【背景技术】【Background technique】
目前,随着社会进步和经济发展，汽车已广泛进入家庭。车灯是汽车的重要组成部分，其在车辆行驶及保证行车安全方面具有重要的作用。长期以来，汽车车灯一直沿用卤素灯和疝气灯，它们虽可满足基本的使用要求，但也存在工作温度高、电能消耗大、输出光效低、使用寿命短、光衰大、启动有延时等明显缺陷。如55W/12V的卤素灯在使用中，其灯泡附近的温度大于250℃，而目前汽车大灯的灯杯大多采用塑料成型，并在灯杯内表面电镀反光材料形成反光层，在上述高温作用下，灯杯的反光材料会加速老化并脱落。目前汽车大灯都采用密封方式，热量靠灯体自然冷却。由于灯杯前部大都采用透明度高的塑料制成，而灯珠前方塑料壳体的温度超过100℃，导致汽车大灯前方的透明塑料加速老化并发黄，使用一段时间后，透光率会下降，使得灯光输出减弱，危害行车安全。现有卤素灯的功率为55W，光通量在1000LM(流明)左右，每W光通量输出18LM左右。现有卤素灯的使用寿命约3000小时左右，使用3000小时后，光通量已经降至初始值的75％以下。同时，卤素灯使用钨丝做发光体，通电点亮后其中心温度高达2600度。At present, along with social progress and economic development, automobiles have widely entered families.

Although they can meet the basic requirements of use, they also have high operating temperature, large power consumption, low output light efficiency, short service life, large light decay, and delayed start-up. time and other obvious defects. For example, when a 55W/12V halogen lamp is in use, the temperature near the bulb is greater than 250°C. At present, the lamp cups of automobile headlights are mostly made of plastic, and the inner surface of the lamp cup is plated with reflective materials to form a reflective layer. Under normal circumstances, the reflective material of the lamp cup will accelerate aging and fall off. At present, the headlights of automobiles are all sealed, and the heat is naturally cooled by the lamp body. Since the front part of the lamp cup is mostly made of high-transparency plastic, and the temperature of the plastic shell in front of the lamp bead exceeds 100°C, the transparent plastic in front of the car headlight will accelerate aging and turn yellow. After a period of use, the light transmittance will decrease. Decrease, so that the light output is weakened, endangering driving safety. The power of the existing halogen lamp is 55W, the luminous flux is about 1000LM (lumen), and the luminous flux output per W is about 18LM. The service life of the existing halogen lamp is about 3000 hours, and after 3000 hours of use, the luminous flux has dropped to below 75% of the initial value. At the same time, the halogen lamp uses tungsten wire as the illuminant, and its core temperature is as high as 2600 degrees after being energized and lit.
