Description

灯珠旋转式舞台灯
技术领域
本发明涉及灯，尤其涉及一种灯珠旋转式舞台灯。
背景技术
在舞台表演过程中，为了提高舞台效果，会设计舞台灯（同一个舞台灯发出的光可以一种或多种）来使得舞台的同一个区域的亮度和光照颜色产生差异。现有的舞台灯为达到以上光效为通过电机驱动灯整体摆动或旋转来完成的，旋转产生的磨损容易导致灯的连接处产生损坏而脱落，从而影响等使用时的安全性。
发明内容
本发明提供了一种旋转过程中不会导致灯损坏而掉落的灯珠旋转式舞台灯，解决了现有的舞台灯通过电机驱动着整体进行转动而导致的容易磨损脱落致使用安全性差的问题。
以上技术问题是通过下列技术方案解决的：一种灯珠旋转式舞台灯，包括旋转罩、连接座、若干LED灯珠和连接在连接座上的灯壳，所述旋转罩上设有灯珠安装柱，所述LED灯珠沿旋转罩周向分布且安装在所述灯珠安装柱的周面上，所述连接座和灯壳围成光源安装腔，所述旋转罩位于所述光源安装腔内且转动连接在所述连接座上，所述连接座和旋转罩之间形成气室，所述连接座设有同气室连通的进气通道，所述旋转罩上设有若干连通气室和光源安装腔的出气通道，所述出气通道位于光源安装腔一端的端口的开口方向线同所述旋转罩的径向交叉，所述灯壳和旋转罩为遮光结构，所述灯壳上设有若干出气孔。使用时本发明通过安装座进行安装，经进气通道将压缩空气输入灯内后从出气通道流入光源安装腔最后从出气孔流出，压缩空气从出气通道流向光源安装腔时产生的气流驱动旋转罩转动从而实现LED灯珠转动，从而使得从出气孔内射出的灯光效果产生变化。本技术方案由于仅位于灯内的灯珠安装柱转到而灯的外壳是不转动的，故即使转动此时磨损脱落也只是光源脱落在等内部、不会产生灯掉落而影响安全的现象。本技术方案中的给旋转罩供气而驱动旋转罩转动的气路设计方式，有效而巧妙地解决了旋转罩旋转过程中气管会产生缠绕的问题。通过气流产生旋转，气流还能够起到对LED进行散热的作用。
作为优选，所述出气通道位于光源安装腔一端的端口的开口方向线同所述旋转罩的径向垂直。能够提高气流驱动旋转罩转动时的驱动效果。
作为优选，所述旋转罩通过平面轴承转动连接在所述连接座上，所述旋转座通过密封圈同所述连接座密封连接在一起。能够防止漏气而降低气流驱动旋转罩旋转的效果。
作为优选，所述连接座上设有定导电环，所述旋转罩上设有同所述定导电环转动抵接在一起的动导电环，所述LED灯珠同所述动导电环电连接在一起，所述定导电环连接有电源线。实现了外部的电源引入给旋转的LED供电。
作为优选，所述电源线穿设在所述进气通道内。布局时方便。
作为另一优选，所述旋转罩上还设有给所述LED供电的电池。
作为优选，所述LED发出的光至少包有两种颜色。能够提高舞台效果。
本发明具有下述优点：不需要电机实现了灯的旋转；旋转产生在灯的内部，安全性好；给旋转罩供气的技术方案有效而巧妙地解决了旋转罩旋转过程中气管会产生缠绕的问题。
附图说明
图1为实施例一的示意图。
图2为图1旋转罩的横截面的示意图。
图中：旋转罩4、连接座5、LED灯珠6、灯壳7、灯珠安装柱8、光源安装腔9、平面轴承10、密封圈11、气室12、进气通道13、出气通道14、出气通道位于光源安装腔一端的端口的开口15、出气孔18、定导电环20、电源线21、动导电环22。
具体实施方式
下面结合附图与实施例对本发明作进一步的说明。
实施例一，参见图1和图2，一种灯珠旋转式舞台灯，包括安装座1、旋转罩4、连接座5、若干LED灯珠6和连接在连接座上的灯壳7。LED灯珠6具体为连接在设置在旋转罩的外端面上的灯珠安装柱8的周面上。LED灯珠沿旋转罩的周向分布在灯珠安装柱上。LED灯珠有4颗，每一颗LED发出一种颜色的光、也即4颗LED发出4种颜色的光。连接座和灯壳围成光源安装腔9。旋转罩位于光源安装腔内且通过平面轴承10转动连接在连接座上。旋转座通过密封圈11同连接座密封连接在一起。连接座和旋转罩之间形成气室12。平面轴承位于气室内。连接座设有同气室连通的进气通道13。旋转罩上设有若干连通气室和光源安装腔的出气通道14。出气通道位于光源安装腔一端的端口的开口15方向线同旋转罩的径向交叉、本实施例中为垂直。灯壳上设有若干出气孔18。连接座上设有定导电环20。定导电环连接有电源线21。电源线穿设在所述进气通道内。旋转罩的内周面上设有同定导电环转动抵接在一起的动导电环22。 LED灯珠同动导电环电连接在一起。使用时通过电源线引入电源给LED灯珠。使用时本发明通过安装座进行安装，经进气通道将压缩空气输入灯内后从出气通道流出，压缩空气从中间通道流向光源安装腔时产生的气流驱动旋转罩转动从而实现LED灯珠转动，从而使得从出光孔内射出的灯光效果产生变化。压缩空气从出气孔流出，LED灯珠产生的光也从出气孔流出时。灯壳和旋转罩为遮光结构已即为不透光的。
实施例二，同实施例一的不同之处为：旋转罩上还设有给所述LED供电的电池。也即LED灯珠为通过电池供电的，而不是同电源线、动导电环和定导电环进行供电的，故没有设置电源线、动导电环和定导电环。
