【摘要】 LED是一种新型半导体光源,具有能耗低、寿命长、响应时间短的优点。LED光源驱动电路复杂,使得LED在工业领域中的应用受到限制。从LED的发展和特点出发,结合LED的恒流发光特性,考虑工业产品中电源电压低的因素,设计LED驱动电路,通过试验进行分析和优化,在保证光源亮度的同时降低了光源的能耗,将其应用于车用光源的设计当中。更多还原

【Abstract】 LED is a kind of new lamp-house, which may save energy. It has a very long-life and a short respond time. The design of LED drive circuit is very complex, so it’s use was limited. In this paper, from the development of LED technology and considering the factor of constant current when it light and low voltage of electrical source, designing drive circuit, analyzing and optimizing through experimentation, it makes lamp-house need low energy without influence of brightness and uses it in designing automobile lamp-house.更多还原
