The invention relates to the technical field of high-power LED lamps, and discloses high-power LED lamps with high heat dissipation efficiency, including a bracket, a radiator placed under the bracket, a light-emitting component arranged at the lower end of the radiator, and a The fan between the bracket and the upper end of the heat sink, the light-emitting component has a high-power LED for lighting, and the bracket has a first cavity communicating with the fan. Compared with the prior art, most of the heat emitted by the high-power LED in the light-emitting component is transferred to the heat sink, and then dissipated to the outside. Since there is a fan between the bracket and the heat sink, it can rotate by itself , Increase the air convection between the radiator and the outside, thereby speeding up the heat dissipation on the radiator, and greatly improving the heat dissipation efficiency of the lamp.
Description
technical field [0001] The invention relates to the technical field of high-power LED lamps, in particular to high-power LED lamps with high heat dissipation efficiency. Background technique [0002] LED lamps are used more and more widely in the present, in order to improve their service life and luminous efficiency, it is necessary to greatly improve their heat dissipation efficiency. [0003] At present, LED lamps generally use aluminum extruded materials to dissipate heat, that is, increase the contact area between the aluminum substrate with LED and the air to improve the heat dissipation efficiency of LED lamps, but for high-power LED lamps, the heat dissipation effect of the above heat dissipation method is not obvious. For effective heat dissipation, the heat dissipation efficiency is low. Contents of the invention [0004] The purpose of the present invention is to provide a high-power LED lamp with high heat dissipation effect, aiming at solving the problems of ...
