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.
