一种自散热型LED射灯
本专利技术属于LED照明设备领域,尤其是涉及一种自散热型LED射灯。
技术介绍
灯具,是指能透光、分配和改变光源光分布的器具,包括除光源外所有用于固定和保护光源所需的全部零部件,以及与电源连接所必需的线路附件,为了更好地实现采光和烘托气氛,经常会用到LED射灯。由于射灯的特殊用途,其一般安装在吊顶四周或家具上部,也可置于墙内、墙裙或踢脚线里,使得射灯的周围空间较小,或是空气流通性较差,导致射灯灯具在工作过程中产生的热量很难通过空气对流进行散热,热量聚集在射灯的周围,导致射灯的工作环境温度较高,容易使内部线路出现老化的问题,不但会减少其使用寿命,还容易造成短路、电起火等严重情况。为此,我们提出一种自散热型LED射灯来解决上述问题。
技术实现思路
本专利技术的目的是针对现有的射灯散热效果差的问题,提供一种液冷式的自散热型LED射灯。为达到上述目的,本专利技术采用了下列技术方案:一种自散热型LED射灯,包括圆筒形的壳体,所述壳体内安装有LED灯头,所述壳体的侧壁两侧均设有弧形腔,所述弧形腔内滑动密封连接有永磁滑块,所述壳体的侧壁上设有散热腔,所述散热 ...
