Light emitting diode lamp with functions of heat convection and heat conduction and heat radiation module thereof

Abstract

The invention relates to a light emitting diode lamp with functions of heat convection and heat conduction and a heat radiation module thereof. The heat radiation module comprises a lamp shell with a plurality of holes in pattern, and a light source surface covering plate arranged at one end of the lamp shell. The light source surface covering plate comprises a plurality of through holes through which a light emitting diode light source can pass, and an outside opening. The outside opening is provided with a metal heat racking pipe extending towards the inside of the lamp shell. When the light emitting diode emits light to rise the ambient temperature, as the density of the hot air of the outside opening is lower, a relative pressure is generated by the cold air which is at an inside opening opposite to the other end of the heat racking pipe and has a higher density, so the hot air continues to flow inwards the lamp shell along the heat racking pipe, enters the lamp shell and then is dispersed from the holes in pattern. Therefore, the invention enhances the heat conduction and generates the heat convection by taking advantage of the metal heat racking pipe so as to achieve good heat radiation effect.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp and a heat dissipation module thereof which utilize heat convection and heat conduction to quickly dissipate heat. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a semiconductor element. It is often used for indicator lights, display panels, etc.; with the emergence of white light-emitting diodes, it is also used for lighting purposes, with high efficiency, long life, and unbreakable advantages that traditional light sources cannot match. [0003] LED lamps also generate heat when they emit light. In order to dissipate heat, most LED lamps use metal (such as aluminum) heat dissipation fins to increase the surface area of ​​heat conduction of the lamps.

[0003] LED lamps also generate heat when they emit light. In order to dissipate heat, most LED lamps use metal (such as aluminum) heat dissipation fins to increase the surface area of ​​heat conduction of the lamps. However, during the heat dissipation process, the surrounding fins are still The hot air and the lack of air convection greatly reduce the cooling effect of the cooling fins. Therefore, it is necessary to improve the cooling method of LED lamps
