| 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. |
