The invention discloses a high-power LED light source system heat management structure which comprises a heat dissipation structure, the heat dissipation structure comprises a soaking part and a heat dissipation part, the soaking part comprises an evaporation section, a condensation section, a condensation working medium arranged in the soaking part and non-condensable gas arranged in the soaking part, the condensation section exchanges heat with the heat dissipation part, and a gas storage chamber is arranged in the heat dissipation part. The air storage chamber is of a variable-volume cavity structure, arranged at the end of the condensation section and communicated with the interior of the condensation section, and the volume control assembly is used for enabling the volume of the air storage chamber to be increased along with increase of the thermal load of the high-power LED light source system and enabling the volume of the air storage chamber to be reduced along with reduction of the thermal load of the high-power LED light source system. The heat dissipating capacity of the heat dissipating structure can be accurately and automatically adjusted according to the change of the thermal load of the high-power LED light source system, so that the temperature of the high-power LED light source system can be kept constant and does not change along with the change of the thermal load, and the light source system has high illumination stability.
Description
technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a thermal management structure of a high-power LED light source system. Background technique [0002] High-power multi-channel LED light source system: composed of multiple lamp beads with different wavelengths, such as R—red light, UV—ultraviolet light, G—green light, B—blue light. Through different opening and closing combinations of lamp beads, as well as the layout of the optical path, the entire optical path system can realize the output of light of various wavelengths. That is to say, if the user only needs G——green light output, other lamp beads can be turned off as much as possible; if the user needs white light output, all the lamp beads must be fully opened and closed, that is, according to the user's needs, the working power of the entire light source system will vary. Variety. When the number of channel lights increases or decreases, a certain light path th...
