阅读说明：本技术 一种简易遮光排气装置及具有其的舞台灯 (Simple shading exhaust device and stage lamp with same ) 是由 蒋伟楷 其他发明人请求不公开姓名 于 2019-05-31 设计创作，主要内容包括：本发明公开了一种简易遮光排气装置,包括相对设置且相互间隔的通风板与遮光板,通风板上设置有通风口,通风口由通风板冲切形成,遮光板在通风板上的垂直投影覆盖通风口。上述简易遮光排气装置,遮光板在通风板上的垂直投影覆盖通风板上的通风口,所以遮光板可以避免光线自通风口泄露出去,而气流可以自遮光板与通风板之间的间隙流出,遮光板、通风板均为普通的平板,不须特殊设计,可以直接冲切形成,且通风板上设置的通风口也是冲切形成,可以在制作通风板时,同时加工通风口,相较于制作百叶窗更加容易,整个简易遮光排气装置的制作也更加简单,仅仅由两块相互固定的普通的平板即可实现较佳的遮光通风效果,有效降低组装时间与生产成本。(The invention discloses a simple shading exhaust device which comprises a ventilating plate and a shading plate which are oppositely arranged and spaced, wherein a vent is arranged on the ventilating plate, the vent is formed by punching the ventilating plate, and the vent is covered by the vertical projection of the shading plate on the ventilating plate. Above-mentioned simple and easy shading exhaust apparatus, the vent on the vertical projection of light screen on the ventilating board covers the ventilating board, so the light screen can avoid light to reveal out from the vent, and the air current can flow from the clearance between light screen and the ventilating board, the light screen, the ventilating board is ordinary flat board, need not special design, can direct die-cut formation, and the vent that sets up on the ventilating board also is die-cut formation, can be when the preparation ventilating board, the simultaneous processing vent, it is easier in the preparation shutter relatively, whole simple and easy shading exhaust apparatus's preparation is also simpler, only can realize the shading ventilation effect of preferred by two mutual fixed ordinary flat boards, effectively reduce equipment time and manufacturing cost.)

技术领域

本发明涉及散热技术领域，更具体地，涉及一种简易遮光排气装置及具有其的舞台灯。

背景技术

为保证舞台灯光源的正常使用寿命，需要维持一个相对比较稳定的环境，因此常常将光源置于一个相对密闭的小环境，外部设置有风机装置将光源腔外部冷风鼓入到光源腔密闭空间内，光源腔密闭空间设置一处出风口，光源腔内的热气流经该出风口排出灯体外，因为光源腔内有强光，为避免光线漏出影响灯具效果，在出风口需要设置挡光结构，该挡光结构既要利于排气，又要能有效挡光，而且还要能方便拆下来更换光源。传统的方案是在出风口上安装百页窗散热器，这种散热器的结构以及生产加工工艺通常比较复杂，百页窗散热器的框架及叶面均需单独生产，然后再进行组装，成本较高。
