Internal circulation cooling system of stage lamp

Abstract

The invention discloses an internal circulation heat dissipation system of a stage lamp. The system comprises a supporting arm, a lamp holder and a circulating heat dissipation system. The lamp holderis pivoted with the supporting arm through a pivoting shaft; the pivoting shaft is of a shaft tube structure; the internal space of the lamp holder is communicated with the internal space of the supporting arm through a pivot shaft, the circulating heat dissipation system comprises a cooling medium, a heat dissipation assembly located in the supporting arm and a power assembly for promoting the cooling medium to circularly flow between the lamp holder and the heat dissipation assembly through a shaft tube structure, and the cooling medium is isolated from the external space of the stage lamp.The cooling medium is driven by the power assembly to circularly flow between the lamp holder and the supporting arm through the pivoting shaft of the shaft tube structure so as to bring out the heatin the lamp holder and carry out heat dissipation on the supporting arm through the heat dissipation assembly, the heat dissipation space is increased and the heat dissipation efficiency is improvedwhile the sealing performance of the lamp holder is guaranteed, and the size of the lamp holder is effectively reduced as the heat dissipation assembly is arranged in the supporting arm compared withthe prior art that the heat dissipation assembly is arranged in the lamp holder.

Description

technical field [0001] The present invention relates to the technical field of stage lamps, and more specifically, to an internal circulation cooling system for stage lamps. Background technique [0002] The current stage lights have more and more functions and more sophisticated structures, so it is necessary to prevent dust or liquid from entering the interior of the lamp body and damaging the internal components. However, because the power of stage lights is generally very large, it usually requires rapid ventilation and heat dissipation, especially the lamp head of stage lights, which generates the most heat and needs waterproof and dustproof the most. At present, most stage lights use the air convection inside and outside the lamp head to achieve rapid heat dissipation. For stage lights that require high waterproof performance, the heat in the lamp head is usually channeled to the shell of the lamp head, and the heat between the shell and the outside is used. Swapping ...
