资料介绍

汽车车灯中光导转向灯的应用越来越广泛。结合一种LED转向灯的设计要求,分析并比较不同车灯LED驱动电路的特点,给出低成本的电路方案;根据诊断反馈的要求,给出在车灯工作电压范围内能满足正确反馈要求的诊断电路。通过电路仿真证实了该电路方案的可行性,为今后类似的设计要求提供了参考方案。

The application of light guide in automotive lighting becomes wider. By combining one design requirement about LED turning light,the different LED drive circuits’ characteristics were analyzed, and a low-cost circuit design was proposed. Besides, according to the requirement of feedback diagnostic, a circuit which could fit the design requirement in the range of automotive lighting test voltage was proposed. Finally, the circuit simulation verifies the design feasibility, and it can be used in similar projects.
