Abstract

The invention relates to the technical field of high-power LED lamps and discloses a high-power LED lamp with high heat radiating efficiency. The LED lamp comprises a support, a radiator, a light emitting component and a fan, wherein the radiator is arranged below the support, the light emitting component is arranged at the lower end of the radiator, the fan is arranged between the support and the upper end of the radiator, the light emitting component is provided with a high-power LED for emitting light, and a first through cavity communicated with the fan is formed in the support. Compared with the prior art, the high-power LED lamp has the advantages that most of heat emitted during working of the high-power LED of the light emitting component is transmitted to the radiator and is further radiated to the outside; the fan is arranged between the support and the radiator, and air convection between the radiator and the outside can be increased through rotation of the fan, accordingly, radiation of heat on the radiator is accelerated, and the radiating efficiency of the lamp is greatly improved.

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 ...
