Description

technical field [0001] The invention relates to a dustproof and waterproof multipurpose LED light power source assembly. Background technique [0002] LED has the advantages of high luminous efficiency, power saving and long life, and its application is more and more extensive. LEDs are used in daily lighting. In order to meet the illumination requirements, it is generally necessary to concentrate multiple power LEDs on one lamp. Therefore, the heat dissipation of LEDs has become an important factor affecting the use and life of LED lamps, especially for high-power LED lamps. Heat dissipation has become a technical bottleneck affecting its wide application. Traditional LED lamps are all passive heat dissipation, that is, heat is dissipated through radiator fins or similar devices. In order to improve the heat dissipation effect, it is necessary to increase the heat dissipation area as much as possible. As a result, the existing LED lamps are generally large in size and comp...

Problems solved by technology

[0003] In addition, at present, thermally conductive silicone grease or thermally conductive insulating cloth is generally used between the light source board and the heat sink for insulation and heat conduction. The thermal conductivity of thermally conductive silicone grease is 3W / (m·K)~4W / (m·K). The thermal conductivity of the cloth is 2W (m·K) ~ 3W / (m·K), the thermal conductivity of the two is low, and the thermal conductivity is poor; the thermal conductive silicone grease is in the form of a paste with an unstable shape, so it is used in the light source board and heat dissipation. It is difficult to apply thermally conductive silicone grease between the radiators evenly. On the one hand, it will lead to poor thermal conductivity, and on the other hand, it will reduce the insulation performance between the light source board and the radiator, and may even cause a short circuit between the two; Cloth-like, easy to change shape, it is difficult to evenly distribute the thermal insulation cloth between the light source board and the heat sink, and the installation is troublesome and the efficiency is low
