6、成电路 LED驱动 I. INTRODUCTION 1:介绍 IN the last few years LED technology experienced a very fast 在过去的几年中,发光二极管技术 在汽车照明应用中替代普通灯泡 经历了一个非常快速的进步时代, and important growth, superseding the bulb technology in automotive lighting applications 1. To achieve the harsh requirement of CO2 emission and reduce the fuel
7、 consumption, car manufacturer must reduce the total power consumption. The 为了实现了严格的二氧化碳排放要求和降低了燃料的消耗 , 汽车制造商必须减少总的功率消耗。 adoption of LEDs in place of bulbs permits to have about five times less power consumption at equal output lighting intensity. 采用发光二极管代替灯泡在同等输出功率照明强度下损耗将降低五倍。 LEDs have reached quality and reliability factors that permit their use in automotive harsh environment and in addition 发光二极管已达到质量和可靠性因素 ,可保证他们可使用在汽车的严
