Title:
STAGE LAMP HEAT DISSIPATION SYSTEM, STAGE LAMP USING SAME AND HEAT DISSIPATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/070716
Kind Code:
A1
Abstract:
Disclosed are a stage lamp heat dissipation system, a stage lamp using the system and a heat dissipation method thereof. The stage lamp heat dissipation system comprises a light source (1), a first light reflecting assembly (2) surrounding the light source (1), a fixing seat (3) for fixing the light source (1), and a heat dissipation assembly (4) surrounding the outer circumferential surface of the first light reflecting assembly (2); the heat dissipation assembly (4) is formed by stacking up a plurality of heat sinks (41), and there are gaps between the plurality of stacked adjacent heat sinks (41), so as to form an air duct (411) for airflow circulation; the air duct (411) is formed in such a manner that there is an air inlet at one end and an air outlet at the other end and the air inlet and the air outlet are directly communicated with each other; an air feed device (5) is arranged at the position of the air inlet of the air duct (411). With such an arrangement, a cooling airflow fed by the air feed device (5) flows annularly along the air duct (411) and comes into direct contact with the outer circumferential surface of the first light reflecting assembly (2); fast heat exchange of the cooling airflow with the first light reflecting assembly (2) and the light source (1) can be achieved, enabling the heat produced at the light source (1) during operating to be discharged timely and effectively.
