LED bulb lamp is an alternative to traditional incandescent light bulb type energy saving lamp. Traditional incandescent lamp (filament ) high energy consumption, short service life, in the global resource environment, has been gradually used by governments to ban the production, instead is the product of electronic energy-saving lamps, electronic energy-saving lamps while enhancing the effect of energy saving, but due to the use of a lot of environmental pollution of heavy metals, but also runs counter to the environmental protection big trend. With the rapid development of LED technology of LED lighting has become a new green lighting choice. LED in the light principle, energy saving, environmental protection level and are far superior to the traditional lighting products. As a result of the incandescent lamp and electronic energy-saving lamps in the people's daily use still occupy a very high proportion, in order to reduce waste, LED lighting manufacturers must be in line with the development of the existing interface and people accustomed to the use of the LED lighting products, make people do not need to change original traditional lamp base and a line of cases can be used as a new generation of LED lighting products. So LED bulb lamp will emerge as the times require. LED bulb lamp uses the existing interface mode, i.e., jack screw mode ( E26 \ E27 \ E14 \ B22 ), even in order to meet the people's habits to imitate the incandescent light bulb shape. Based on the LED unidirectional light principle, design staff in the lighting structure of the change makes the LED bulb lamp light distribution curve and incandescent lamp light convergence. Based on the luminescence properties of LED, LED bulb lamp structure is relatively complex points of incandescent lamp, light source, driving circuit and radiating device, these parts together to create low energy consumption, long life, high Guangxiao and environmentally friendly LED bulb lamp products. So LED lighting products at present, still is a high technology content of the high-tech lighting products.
