摘要:LED照明作为第四代照明技术，因其具有工作电压低、功耗小、体积小、重量轻、易于和集成电路相匹配、驱动简单、寿命长、性能稳定、响应速度快等一系列优点，而被广泛地应用于各种领域。LED克服了自身只能在低电压直流的工作条件下正常工作的缺陷，可以直接使用220V交流电，使得应用更方便。而传统卤素灯虽然比原始上的白炽灯性能优越很多，但依然存在诸如耗能高，发光效率低，使用过程中极易造成损坏等许多不足。于是促使了LED代卤素灯成为目前LED照明研究的一个新热点，其特点是光效高，不易损坏等。LED的光效几乎是普通卤素灯的近10倍。因此本课题的研究在LED应用领域有着非常重要的意义，也在完善传统卤素灯照明性能的研究中前进了一大步。31284

Design and photoelectric performance analysis of LED halogen lamp
Abstract：LED lighting as the fourth generation lighting technology, because of its low operating voltage, low power consumption, small volume, light weight, easy and integrated circuit matching, easy driving, long service life, stable performance, response speed and a series of advantages, and was widely application in various fields. LED overcomes the defects of normal operation under the condition of low voltage DC, and can use 220V alternating current directly, making it more convenient for application.. While the traditional halogen lamps than the original incandescent lamp performance is superior, but still exist such as high energy consumption, low luminous efficiency, the use of extremely easy cause damage and many other issues. As a result, the LED generation of halogen lamps has become a new hot spot in the research of LED lighting, which is characterized by high efficiency and hard damage. The light effect of LED is almost 10 times of the ordinary halogen. So this research is very important in the field of LED application, and a big step in the research of the traditional halogen lamp's lighting performance.
