Technical difficulties LED lights produce a relatively high need, oh, one is LED option. LED brightness is difficult now generally up to a certain level, but the lights are strict requirements for the light shape and illumination of corresponding points. For headlight: optical design is required according to standard requirements of shaped light, including LED brightness, beam profile, the beam angle is selected design. Although capable of LED energy saving and the small size, but its narrow beam angle of the LED heat treatment are higher, so the led lights used as a treatment for dodging need special attention. The other is for LED heat treatment, if the heat is not good to do, not only will affect the life of the LED, but also causes the LED light attenuation occurs in light-emitting devices, based on these two limits, LED lights have not been well development, only a few high-end car assembly. An Mingpu Guangzhou Auto Parts Co., Ltd. is a research and development, led lights production, processing, sales and service in an integrated service enterprises; main products are led lights, led car lights converted H4 led lights shell, high brightness led lights, led lights Audi price, welcome to consult purchase! 1. The reliability and service life 2. Efficiency / lumens per watt incandescent compared with the standard, LED consumed per unit of electrical energy can produce more light output. However, when compared with the halogen lamp, the advantages of the actual light output of the LED is not obvious. The latest LED lumens per watt with outstanding value H4 led lights, but some values ??are obtained under optimized conditions, but usually not in a condition to obtain the maximum output. In general, when the LED current increases, light output does not increase linearly. So H4 led lights supplier, even if the LED at 0.5A current output x lumens, it is not at 1.0A current output 2x lumens. 3. The response rate to the brake lights and direction indicators tube, for example, assume that a vehicle speed of 125 km / h, or 35 m / s, hot incandescent start time is about 250 milliseconds, and responsive LED can advance about 8 meters away from the brake warning issued to effectively avoid car collision. Indicator as well. 4. directional Another key feature is the LED light way. Different incandescent, LED luminous only through a surface, which charts the lamp headlights and beneficial applications, but may not be suitable for car lighting other lighting applications.
