Description

一种舞台灯内循环散热系统 技术领域
本发明涉及舞台灯技术领域，更具体地，涉及一种舞台灯内循环散热系统。
背景技术
目前的舞台灯功能越来越丰富，结构也越来越精密，所以需要避免尘土或者液体进入所述灯体内部，损坏内部元件。但是由于舞台灯的功率一般都很大，所以又通常需要快速的通风散热，尤其是舞台灯的灯头，发热最为严重，也最需要防水防尘。现在大部分舞台灯都是利用灯头内外的空气对流来实现快速散热，对于防水性能要求很高的舞台灯，通常是将灯头内的热量疏导至灯头的壳体上，利用壳体与外界的热交换进行散热，效率低下。
发明概述
技术问题
本发明为克服上述现有技术所述的至少一种缺陷，提供一种舞台灯内循环散热系统，将舞台灯的灯头内的热量疏导至支撑臂内，利用所述支撑臂进行散热，在保障所述灯头密封性的同时，增大了散热空间，提高了散热效率。

进一步地，所述灯头通过两个所述枢接轴与所述支撑臂相枢接，两个所述枢接轴均为轴管结构，所述冷却介质分为两股，每股所述冷却介质分别仅通过一所述枢接轴在所述灯头与一个所述散热组件之间循环流动。利用两股所述冷却介质进行散热，散热效率更高。
可选的，两股所述冷却介质在所述灯头内混合后，在分别通过一个所述枢接轴流出。
进一步地，所述散热组件包括散热鳍片、从所述散热鳍片中穿过的用于导流所述冷却介质的导流管以及对所述散热鳍片进行散热的散热风扇，所述支撑臂对应所述散热风扇设置有通风口。所述冷却介质从所述导流管中流过，并被所述散热鳍片吸收热量，然后所述散热风扇对所述导流管及所述散热鳍片进行散热，并从所述通风口将热量导出舞台灯之外，实现舞台灯的快速散热。
