Title:
CIRCULATING HEAT DISSIPATION SYSTEM IN STAGE LAMP
Document Type and Number:
WIPO Patent Application WO/2021/082232
Kind Code:
A1
Abstract:
A circulating heat dissipation system in a stage lamp, the circulating heat dissipation system comprising a support arm (200), a lamp holder (100) and a circulating heat dissipation system body. The lamp holder (100) is in a pivot joint with the support arm (200) by means of a pivot joint shaft (300), the pivot joint shaft (300) is of a shaft tube structure, an inner space of the lamp holder (100) is in communication with an inner space of the support arm (200) by means of the pivot joint shaft (300), the circulating heat dissipation system body comprises a cooling medium, heat dissipation assemblies (211, 212) located in the support arm (200), and power assemblies (410, 420) promoting the cooling medium to circularly flow between the lamp holder (100) and the heat dissipation assemblies (211, 212) by means of the pivot joint shaft (300), and the cooling medium is isolated from an external space of the stage lamp. The cooling medium is driven by the power assemblies (410, 420) to circularly flow between the lamp holder (100) and the support arm (200) by means of the pivot joint shaft (300) of the shaft tube structure, heat in the lamp holder (100) is brought out, heat dissipation is conducted on the support arm (200) by means of the heat dissipation assemblies (211, 212), a heat dissipation space is enlarged while the sealing performance of the lamp holder (100) is guaranteed, the heat dissipation efficiency is improved, and in addition, due to the fact that the heat dissipation assemblies (211, 212) are arranged in the support arm (200), compared with the heat dissipation assemblies (211, 212) being arranged in the lamp holder (100) in the prior art, the size of the lamp holder (100) is effectively reduced.
