摘要目前LED灯凭借着其高效节能、长寿命、色彩丰富和环保等特点,在国外新型摩托车上的应用已经较为广泛,大有取代传统钨丝白炽灯、卤素灯,甚至于HID氙气灯之势;而国产摩托车用LED灯具才起步不久,LED摩托车前照灯也是刚刚开始。作为车载照明的一项关键技术,LED前照灯仍然有很多难题需要攻克,配光设计、散热问题等等,由于LED灯不同于以往的的照明灯具,所以原有的设计都不能满足,需要进行重新设计。49441

本文设计了一款LED摩托车前照灯,对它的灯罩,发光单元,电路板等重要组成部分作了简单的介绍,对系统的散热和驱动,进行了研究。此设计结合传统设计的优点,既符合了产品简洁、环保、高效、节能的特点,又最大程度上提高了产品的性能与寿命。

Abstract With its high efficiency and energy conservation, the long life, rich color environmental protection and other characteristics, the use of LED lamp becomes more and more widely in the application of the new motorcycle abroad. And it has a tread of replacing traditional incandescent lamp, tungsten halogen lamp, even potential of the xenon HID lights . Besides, the domestic motorcycle lamp with LED starts quickly and motorcycle lamp of inland is just beginning to remove . As a key technology of LED headlamps lighting, there are still many problems which need to be conquered, such as lights, heat dissipation issues, and so on . As the LED lights are different from former lighting lamps and lanterns completely, which the original design would not satisfy with,have to be redesigned . 

      This paper is a design of LED motorcycle headlamp. We recommend the shine unit, circuit boards, and other important parts simply, and introduce the system of heat and drive. This headlamp consists the advantages of traditional design, which is not only fit for the concise, environmental protection, high efficiency, energy-saving characteristics, but also it enhances the performance and life .

Keywords:LED  motorcycle headlamps; LED drive system ;LED cooling
