LED bulb adopts the existing interface mode, namely, the screw mouth, the socket Way (E26, etc.), even in order to conform to people's use of the habit of imitating the shape of incandescent bulbs. Based on the light-emitting principle of LED unidirectional, the designer made a change in the structure of the lamp to make the light distribution curve of the LED bulb converge with the point light source of the incandescent lamp.
Based on the luminous characteristics of LED, the structure of LED bulb is relative to the incandescent lamp, which is divided into light source, driving circuit and heat dissipation device, which can create low energy consumption, long life, high luminous efficiency and environmental protection LED bulb products. Therefore, LED lighting products in terms of the present, is still a high technical content of High-tech lighting products.
