Radiating type bulb based on lamp body inner and outer surface multi-layer heat dissipation and air circulation convection

Abstract

The invention discloses a radiating type bulb based on lamp body inner and outer surface multi-layer heat dissipation and air circulation convection. The radiating type bulb comprises a lamp body, wherein a lampshade is arranged on the top of the lamp body; a light-emitting diode (LED) lighting component and a power supply box are arranged in the lamp body; a lamp cap is arranged at the bottom of the power supply box; an aluminum-based plate is arranged between the lamp body and the lampshade; the lamp body is provided with the heat-dissipating inner wall which has the curved section and is formed by arranging a plurality of convex ribs and flowing groove longitudinally in a staggered manner or the spiral heat-dissipating inner wall which is formed by arranging the ribs and the flowing groove transversely; a plurality of bosses are formed between the inner wall and the outer wall of the lamp body; vent holes are formed among the bosses; an air circulation convection heat-dissipating structure is formed between the vent holes and the heat-dissipating inner wall so as to form internal air circulation heat dissipation; and the surface of the lamp body has the heat-dissipating function, so the multi-layer heat dissipation of the inner surface and the outer surface of the lamp body and the surfaces of the inner walls of the vent holes and the air circulation convection heat dissipation can be realized.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a bulb based on multi-layer heat dissipation inside and outside the lamp body and air circulation convection heat dissipation. Background technique [0002] At present, with the development of economy and society and the continuous improvement of LED lighting technology, LED lighting fixtures have been more and more widely used in people's daily life. Instead of traditional incandescent lamps and fluorescent tubes, it has become the mainstream lighting fixtures today. LED bulbs are one of the application fields of LED lighting technology. LED bulbs are mainly composed of lampshades, lamp bodies, LED lighting components, and power boxes. Although LED bulbs have been gradually popularized, but the defect of poor heat dissipation has always been an unsolvable problem, especially for the heat dissipation of the power supply. In view of the above defects and existing problems, it...

[0002] At present, with the development of economy and society and the continuous improvement of LED lighting technology, LED lighting fixtures have been more and more widely used in people's daily life. Instead of traditional incandescent lamps and fluorescent tubes, it has become the mainstream lighting fixtures today. LED bulbs are one of the application fields of LED lighting technology. LED bulbs are mainly composed of lampshades, lamp bodies, LED lighting components, and power boxes. Although LED bulbs have been gradually popularized, but the defect of poor heat dissipation has always been an unsolvable problem, especially for the heat dissipation of the power supply. In view of the above defects and existing problems, it is necessary to propose a new design for the existing LED bulbs. improvement of
