Abstract
Daytime BaiTianKai driving lamp just as its name implies is to refer to the lamp, also means that the lamps and lanterns is not floodlight, not to allow the driver can see pavement, but to let others know there is a car coming in, it is to belong to the category, a special lamp, it in automobile engine start automatically open, help to improve visibility, care to other pedestrian road. When the driver manually open ordinary lamp lighting, daytime driving parade then shut automatically. Installation driving lamp will help reduce by accident, by more than driving lamp because for LED lamp, power consumption is only 25 or 30 percent of the ordinary headlamps, can reduce vehicle electricity consumption, this special day traffic lights of the daytime open ordinary lamp, but also can be more energy-efficient to further reduce carbon dioxide emissions.
Based on the characteristics of vehicle lamp fine day, this system based on single chip daytime studied driving lamp controller design, use high-effect, large current DC - DC converter XL4012 to drive LED lamp, meet the demand of LED consumption large current XL4012 continence, because of traffic lights, daytime controller has very good use value.
Key word: microcontroller, daytime driving lamp, XL401
