Provided are a lamp and a heat radiation method thereof. When a light-emitting element of the lamp works, generated heat is conducted to a heat radiation base, and heat radiation liquid in a liquid storage cavity enters an evaporation cavity through the capillary adsorption force of capillary through holes; the heat radiation liquid and the heat radiation base are subjected to heat exchange, the heat radiation liquid evaporates to be subjected to vaporization phase changes, and vapor generated after vaporization enters a condensation cavity to dissipate heat to the outside of the lamp and be subjected to liquidation phase changes; and the liquefied heat radiation liquid flows back to enter the liquid storage cavity, and therefore the heat radiation liquid is driven based on the capillary adsorption force to cyclically flow in the loop of the cavities to achieve continuous heat radiation operation on the lamp.
Description
technical field [0001] The invention relates to a lamp, in particular to a lamp with improved optical performance and heat dissipation performance and a heat dissipation method thereof. Background technique [0002] As we all know, the light produced by the luminaire will be accompanied by a large amount of heat generation, and how to effectively and efficiently discharge the heat from the external environment of the luminaire when the luminaire is used is crucial to the working stability and service life of the luminaire. important. [0003] The traditional method is to directly or indirectly connect the light source of the lamp to the radiator, and use the radiator to cool the lamp through natural convection or forced convection. Lots of cons. For example, first of all, in order to obtain a good heat conduction effect, the traditional heat sink is usually made of metal materials, so that the weight of the heat sink is relatively large, and the structure of the heat sink ...
