Human life in addition to water, air, food essential supplies, light has been affecting people's rest, has been living a sunrise, sunset and interest in life. Until 1879, Edison invented the light bulb (incandescent lamp), its principle is: when the lamp access circuit, the current flow through the filament thermal effect, so that the incandescent lamp issued a continuous visible and infrared light, this phenomenon in the filament temperature up to 700K can be detected, due to the work of the filament temperature is very high, Most of the energy is wasted in the form of infrared radiation, and because the filament temperature is very high and evaporation is fast, the life span is greatly reduced, about 2,200 hours, and the light effect is about one per watt (Lm). Before the lighting system only pay attention to the quantity, and today has gradually moved towards refinement, pay attention to the effect of saving energy. As a result of the widespread use of lighting technology and lighting equipment, so that people's living standards generally improve, the demand for lighting is increasing, but also make power consumption expanded, so began to pay attention to the development of high efficiency, quality lighting equipment.
