Problems solved by technology
Since the contact area between the thin-plate-shaped fins and the condensation section of the heat pipe is limited, and the thermal resistance of the thin-plate-shaped fins itself is relatively large, and considering the need for heat dissipation, the distance between the fins should not be too small. Therefore, Only a small part of the area of the condensation section of the heat pipe is used to transfer heat through contact with the fins, while most of the area of the condensation section can only dissipate heat through its own contact with the air. Therefore, the heat pipe radiator of this structure Can not give full play to its cooling effect

The invention relates to a heat dissipation method and a device of a high-power LED lamp. The device comprises a heat accumulator, a heat pipe, a condensation section area expander and a radiator, wherein the LED and the a driver device of a direct current constant current power supply are clung to the heat accumulator, an evaporation zone of the heat pipe is embedded in the heat accumulator, a condensation section is embedded in the condensation section area expander; in order to reduce the radiation of the heat energy in the LED lamp, a surface of the heat accumulator and an inner surface of a shell are processed to have lower infrared emitting ability, and an outer surface of the radiator are processed by using materials with different transmitting abilities in visible light wave band and the infrared wave band through a physical or chemical method, so that the radiator not only has higher thermal radiation ability in the infrared wave band, but also has strong ornamental value in the visible light wave band.
Description
Technical field: [0001] The invention relates to a heat pipe heat dissipation technology, and also to an infrared technology, in particular to a method and a device for heat dissipation of a high-power LED lamp. Background technique: [0002] In today's situation of increasingly serious environmental pollution and energy shortage, energy conservation and emission reduction have become the primary issues that need to be solved urgently. Because LED lights have the advantages of energy saving, environmental protection, high efficiency, and long life, their application fields have been continuously expanded. [0003] LEDs emit light through electrical energy-light energy conversion. In the process of LED lighting, about 80% of the total electrical energy is converted into heat energy. If this part of the heat cannot be dissipated in time, the junction temperature of the LED will rise. If things go on like this, it will cause permanent damage to the LED if it is serious, and ...
