[0005] 一种防水舞台灯的灯头结构， 包括灯体支架、 分别设在灯体支架前侧和后侧的 前机头盖和后机头盖、 设在灯体支架上方的镜头组件、 设在灯体支架下方的散 热组件、 设在灯体支架腔体内的光源以及沿主光轴方向设置的若干光学元器件 ， 所述光学元器件与灯体支架的内壁连接固定； 所述镜头组件、 灯体支架和散 热组件均设在前机头盖和后机头盖拼合形成的腔体内； 所述前机头盖、 后机头 盖、 镜头组件和散热组件分别与灯体支架的沿边密封连接， 形成全方位的防水 结构。 [0006] 本发明的技术方案与现有技术的主要不同之处在于， 本发明主要是通过镜头组 件与灯体支架密封连接、 灯体支架与散热组件密封连接、 灯体支架分别与前机 头盖和后机头盖密封连接、 以及前机头盖与后机头盖密封连接， 进而形成一整 体的防水密封结构。
[0007] 其中， 与现有技术不同的是， 本发明主要通过设置前机头盖和后机头盖两盖拼 合， 作为本申请的最外层防水层。 5见有技术中的防水舞台灯在后期维护时， 需 要将各部分的防水层逐一拆卸进行排查， 开模的次数多且安装、 拆卸不方便。 而本发明在后期维护中， 只需将前机头盖和后机头盖拆下， 即可对灯体支架上 的全部元器件一目了然， 进而快速检查灯体支架上的光源或各元器件。
[0008] 前机头盖和后机头盖主要作为本发明防水舞台灯的灯头结构的最外层防水层， 镜头组件、 灯体支架以及散热组件从上到下依次设置在前机头盖和后机头盖两 盖拼合后形成的腔体内， 前机头盖和后机头盖两盖拼合形成的腔体上方开口， 开口位置与镜头组件密封连接， 以供镜头组件出光； 所述前机头盖和后机头盖 在与散热组件位置对应的盖体部分设有供散热组件换热的间隙， 使得散热组件 更好地散发热量。 另外， 为更好地散热， 前机头盖和后机头盖的材质优选为金 属材质， 使得散热组件的热量可通过前机头盖和后机头盖及时散发。
[0009] 进一步地， 所述灯体支架包括呈上下设置的支架顶板和支架底板、 呈左右设置 的左支架侧板和右支架侧板， 所述镜头组件和散热组件分别设在支架顶板和支 架底板上， 且与支架顶板、 支架底板密封连接； 所述支架顶板、 左支架侧板、 支架底板和右支架侧板依次围绕连接， 形成一中空的腔体结构， 中空腔体结构 的外沿边分别与前机头盖和后机头盖密封连接， 所述光源和元器件设在腔体结 构内。
[0010] 所述透镜组件与支架顶板密封连接， 进而保证灯体支架上方的防水密封性能； 所述散热组件与支架底板密封连接， 进而保证灯体支架下方的防水密封性能， 而中空腔体结构的外沿边与前机头盖和后机头盖密封连接， 进而保证了灯体支 架四周沿边的密封防水性能。 因此灯体支架通过镜头组件、 散热组件以及前、 后机头盖形成一全方位的防水密封结构， 而光源以及辅助光源出光的元器件设 在灯体支架的腔内， 进而得到良好的防水密封效果。 [0011] 进一步地， 所述左、 右支架侧板与支架顶板、 支架底板的连接位置之间设有灯 体支架防水胶， 所述支架顶板和支架底板上设有安装灯体支架防水胶的防水胶 槽。
[0012] 在左、 右支架侧板与支架顶板、 支架底板的连接位置之间设置灯体支架防水胶 ， 主要作用是保证左、 右支架侧板与支架顶板的连接位置之间、 以及左、 右支 架侧板与支架底板的连接位置之间具有良好的防水密封性， 进而有效防水。
[0013] 进一步地， 所述左、 右支架侧板分别包括两长边和两短边， 两长边分别与前、 后机头盖连接， 两短边分别与支架顶板、 支架底板连接； 所述灯体支架防水胶 的长度长于左、 右支架侧板短边的长度。
[0014] 所述灯体支架防水胶的长度长于左、 右支架侧板短边的长度， 使得灯体支架防 水胶与左、 右支架侧板的连接位置之间过盈配合， 能有效避免水汽渗透进灯体 支架内， 保证灯体支架的防水性能。
[0015] 进一步地， 所述支架顶板、 支架底板在与左、 右支架侧板的连接位置上设有凸 沿， 所述支架顶板的凸沿呈向下弯的弧状结构， 所述支架底板的凸沿呈向上弯 的弧状结构， 所述左、 右侧板分别卡接在支架顶板、 支架底板的凸沿内。
