Problems solved by technology

However, the patented technology still has the following problems. 1. The heat-conducting insulating layer is made on the substrate, and the substrate and the external heat sink use heat-dissipating glue as the heat-conducting medium, so that the heat can reach the external heat sink through the substrate, and then communicate with the outside air. The heat is exchanged and dissipated, so the problem of the left and right heat dissipation of the heat-dissipating glue has not been improved; 2. The heat-conducting insulating layer is made of diamond powder and epoxy resin. The strength, heat resistance and expansion coefficient of the composition cannot emit light at high power Diodes work stably in an environment with high temperature and frequent switching, which causes the problem of rapid reduction in service life
Combining the above several newly developed technologies shows that the problems related to the integrity of heat conduction have not yet been reasonably resolved

Abstract

The present invention relates to a LED heat emission pattern assembly with high efficiency, and the heat emission pattern assembly directly makes an electric insulation heat conducting layer with diamond element on the heat absorbing end face of the radiator. The metal circuit layer can be provided with one or a plurality of LED components. The pattern assembly structure of the heat emission glue is not used, the present invention solves the problems of heat emission, blocking and piling to keep that the LED works in a normal temperature.

Description

technical field [0001] The invention relates to a light-emitting diode heat dissipation module, which belongs to the technical field of heat dissipation application. The structure of the heat dissipation module can be used in the assembly and use of light-emitting diode elements. Background technique [0002] With the continuous improvement of the power of the light-emitting diode element, the waste heat of work increases and the emission does not increase equally, resulting in the problem that the temperature of the element rises, the working efficiency decreases, and even the element is damaged. Review the commonly used heat dissipation methods, such as light-emitting diode components contacting the heat sink through the circuit board, heat dissipation glue, so that the heat of the electrical components is conducted to the heat sink to be discharged. However, the actual use shows that the current heat dissipation method still has the following three thermal resistance shor...
