Description

一种防止日照损坏的舞台灯 技术领域
本发明涉及舞台灯技术领域，具体涉及一种防止日照损坏的舞台灯。
 背景技术
随着人们生活水平的不断提高、可支配收入的稳定增长、消费观念的不断升级以及文化素质的不断提升，人们逐步对高品质、多元化的文艺演出、旅游观光和娱乐活动等文化艺术产品有了更大的需求。演艺灯光设备作为文艺作品实现的重要载体，同时也是城市亮化工程的重要设备之一，也从户内走向了户外，例如大型体育场馆、游乐园、建筑物外墙、大型露天演唱会舞台场地等。
舞台灯是一种由DMX512信号控制的智能灯具，其光色、光斑、照度均优于常规灯具，是近年来发展起来的一种智能灯具，常安装在面光、顶光、舞台后阶等位置，其运行中的色、形、图等均可编制运行程序。对于安装在户外露天的舞台灯，除了做好防水防尘保护，还要考虑避光保护，因为太阳光直射舞台灯灯头的透镜时，通过透镜会聚焦太阳光产生较大热量，长时间过热会损害舞台灯里边的器件，甚至烧坏舞台灯。
且通常情况下，当灯具处于待机或者非工作状态，由于配重等原因，灯具的出光镜头组件会部分或全部朝向天空，且一般舞台灯安装后位置较为固定，在日照充足的白天，太阳光经过出光镜头组件，直接照射进灯具，导致灯具内部的皮带和塑料材质等类型的组件因高温而被损坏，如皮带最高耐温140℃，塑料制品一般耐温120℃，特别在南方的夏天，日照时间长，再加上镜头有一定的聚光效果，进一步增加了灯具组件内部的温度，大大减低了灯具的使用寿命。
 技术问题
基于此，本发明在于克服现有技术的缺陷，提供一种防止日照损坏的舞台灯，可以实现对舞台灯具内部元件的保护。
 技术解决方案
为了实现上述目的，本发明提供一种防止日照损坏的舞台灯，包括灯体和控制组件，还包括避光系统，当灯体处于通电状态时，所述控制组件控制避光系统不工作；所述灯体处于断电状态时，所述控制组件控制避光系统实现避光动作。
所述避光动作可以是通过转动灯体实现避光或者通过设置在灯体出光端的遮光元件实现遮光也可以根据阳光照射角度的变化实现动态避光等。利用控制组件的控制，实现多种方式的智能避光。
进一步的，所述灯体包括灯头和灯座，以及驱动灯头相对灯座转动的驱动电机，所述避光动作为控制组件控制驱动电机转动，使得灯头避开日照。
利用灯头与灯座的转动连接，当有灯体内部处于通电状态时，控制组件不会控制驱动电机进行避光动作，只有当灯体内部处于断电状态时，所述控制组件才会控制驱动电机转动，驱动电机转轴转动会带动灯头转动，实现避光，因此本发明的避光动作不会影响舞台灯的正常工作，只有在不使用的状态下才会实施避光，操作更加智能。
进一步的，所述避光系统包括用于检测舞台灯重力方向的重力传感器，所述控制组件包括用于计算舞台灯的灯头方向与重力方向夹角α的主控制器，当α处于第一夹角时，所述控制器控制驱动电机驱动灯头转动，调整α的角度至第二夹角，所述第一夹角为太阳光照射到灯头内部的夹角；所述第二夹角为太阳光照射不到灯头内部的夹角。
进一步的，所述第一夹角≥90°，所述第二夹角为0~45°。
重力传感器是新型传感器技术，它采用弹性敏感元件制成悬臂式位移器，与采用弹性敏感元件制成的储能弹簧来驱动电触点，完成从重力变化到电信号的转换。由于舞台灯的安装方式复杂多变，有置于舞台顶部安装的，有侧面安装的，也有水平台阶安装的，而重力方向一般是固定的，因此根据重力方向实时调节灯头的朝向，能够有效避免日光照射进入灯体内部，且调节方式更加智能化。所述避光保护装置是在舞台灯停止工作的情况下开启的，因此，当舞台灯停止工作时，所述重力检测器检测重力方向，并将信号传输至主控制器，主控制器计算此时灯头朝向的方向与重力方向之间的夹角，由于重力方向是垂直向下的，因此当α在90度以内时，此时灯头朝向水平方向，因此灯头内部还是有被太阳照射到的可能，因此，此时调节灯头的想下转动，减小α的角度，实现智能避光。
一般灯头朝向太阳照射的角度在某一角度的照射是最强烈的，而向两侧转动后，照射强度会下降，实现避光。其中第一夹角为太阳光能够穿过灯头照射入灯具内部的角度，而第二夹角为太阳光照射不到灯头内部的夹角。
通过重力传感器检测舞台灯的安装位置，由主控制器计算灯头方向与重力方向的夹角并比较大小，直至计算出最小的夹角角度，即尽量调整舞台灯灯头朝向重力方向，避开太阳光照射灯头透镜。该避光保护装置具有自动识别度高，接入系统灵活，性价比高，实现简单等优点。
需要指出的是，本发明所述的避光系统是在舞台灯光源停止工作的情况下才开始运作的，不会影响舞台灯的正常工作。可以通过设置在舞台灯内部的检测器检测光源是否处于工作状态，由控制器进行进一步的控制。
优选的，当α≥90°时，所述主控制器控制驱动电机驱动灯头转动，调整α的角度至0~15°。
为了更进一步保证灯头内部不会受到阳光的照射，本本发明进一步减小α的角度，设置在0~15°，基本可以避免日光的照射。
进一步的，所述灯座包括底座和灯臂，所述灯头与灯臂转动连接。
所述底座通过紧固件可以固定在舞台顶部，舞台侧墙或者舞台后阶上，其中紧固件可以是固定支架、或者直接同螺纹紧固。其中灯臂连接底座，灯臂与灯头转动连接，使得灯头能够朝向不同的角度，扩大照射范围。
进一步的，所述重力传感器和主控制器设于所述底座中。
为了保证重力传感器感应的更加准确，其安装后的相对位置应该较为固定，因此将其设置在底座中。而主控制器为精密元件，为了避免线路移动造成损坏，同样将其设置在底座中。
进一步的，所述灯臂呈“U”字型，“U”字型灯臂的内侧与灯头转动连接。
设置“U”字型灯臂，使得灯头能够固定在灯臂的内侧，便于灯头的稳固，避免摇晃，影响照射效果。
进一步的，所述灯臂与底座转动连接。
为了实现舞台灯照射角度和照射范围更大，所述灯臂与底座转动连接，可以实现两侧的照射。
进一步的，所述灯头包括圆柱形的光学元件部和圆台形的镜头部，所述光学元件部和镜头部可拆卸连接，所述镜头部上设有透镜。
所述光学元件部内设有光源以及电板等元器件，需要散热，因此设置为圆柱状，增加散热空间，其中镜头部主要安装固定镜头或者其他光学透镜，为了实现更好的聚光，将其设置为圆台状。所述光学元件部和镜头部可拆卸连接，可以是螺纹转动连接，可以实现镜头部的快速更换，便于实现不同的光学效果。
进一步的，所述避光系统包括设于灯体上的太阳能发电板，当灯体处于通电状态时，所述控制组件控制太阳能发电板不工作；所述灯体处于断电状态时，所述控制组件控制太阳能发电板发电，驱动电机利用电能驱动灯头转动，使灯头避开日照。
所述灯体可以安装在室外实现舞台灯光效果。所述控制组件设置在灯体内部，用于控制灯体的开关以及太阳能发电板的工作。针对悬挂式的舞台灯，灯体可通过悬架悬挂在舞台顶部或侧面，灯体与悬架转动连接，当灯体处于断电状态时，所述控制组件控制太阳能发电板发电，驱动系统利用电能驱动灯体转动，使灯体的出光端朝向地面，实现了对灯体内部元器件的保护。
因此，在白天，灯具断电情况下，太阳光经过出光端的镜头，照射到灯具里面，导致灯具的钣金、塑料件、皮带等烧坏，而通过使用太阳能电池板，当有太阳的情况下发电，利用电能驱动灯体的出光端朝向地面，保护了灯具，而且节能环保。且在阴雨天，没有太阳，太阳能电池板不工作，即使灯体的出光端朝向天空，也没有问题，该方案更加智能有效。
进一步的，所述避光系统包括设于灯体出光端的遮光组件，所述避光动作为所述控制组件控制遮光组件闭合，遮挡出光端。
灯体内部还设有光源，可以为LED光源，光源包括出光端，所述遮光组件设置在出光端，可以设置在出光口的位置，便于对灯体的内部零部件进行保护。所述遮光组件可以通过单侧滑动或者双边滑动的方式实现打开和闭合。
因此，本发明通过对遮光组件设置闭合和打开两种状态，并不会对光路有任何影响，且能够根据舞台灯的使用状态改变状态，更加具有针对性，另外，将遮光组件设置在出光端，也是在灯体的内部，结构紧凑，不会额外增加灯体的体积。
进一步的，所述灯体的出光端设有固定镜头和放大镜头，所述遮光组件设于所述固定镜头与放大镜头之间。
其中固定镜头固定安装在出光端，同时实现保护内部构件的作用。所述放大镜头起到增强灯光效果的作用，设置在固定镜头的外侧，为可拆卸连接，可以实现快速的更换。因此光线从光源端发射出，穿过固定镜头后，再从放大镜头发射出，还可在固定镜头与放大镜头之间设置其他的光学功能件，如雾化镜头、图像功能板等，实现多种光学效果。
将遮光组件设置在固定镜头和放大镜头之间，一方面，由于固定镜头对灯体内部的零部件实现了保护，遮光组件能够进一步避免内部零部件受到光照，实现双重的保护，另外，由于放大镜头可拆卸的连接方式，因此通过拆卸放大镜头，可以实现对遮光组件快速检修和维护，节约时间成本，且放大镜头对遮光组件也有一定的保护作用，避免了移动运输时的磕碰损伤。
所述遮光组件包括可开合的遮光板、驱动遮光板开合的驱动系统，所述遮光板与灯体滑动连接，所述驱动系统与控制组件电连接。
所述遮光板可以采用单独的驱动系统，与舞台灯的电源驱动独立开来，其中控制组件与驱动系统也连接，与外接的电源也连接，实现双重控制。当舞台灯处于断电状态时，驱动系统内部的电源能够与控制组件连接，并根据控制组件的指令实现对遮光板的控制。
进一步的，所述遮光板为铝合金、镁合金或塑料材质。
可以将遮光板设置为可拆卸的滑动连接方式，便于拆卸和更换，因此其材料也有多种选择，铝合金、镁合金或塑料材质都可。
进一步的，所述避光系统包括设于灯体内部，用于检测灯体内部通电状态的信号检测器。
所述信号检测器用于检测舞台灯处于通电或者断电的状态，因此可以检测灯体内部的电流情况进行判断。由于舞台灯一般都是外接电源的，因此通过信号检测器能够直观而准确的检测舞台灯的工作状态。
信号检测器可以用于不同避光系统，信号检测器检测到灯体处于通电状态时，所述控制组件控制所述太阳能发电板不工作；信号检测器检测到所述灯体处于断电状态时，所述控制组件控制太阳能发电板发电。
同样的，所述舞台灯还包括设于灯体内部的信号检测器，信号检测器检测到灯体处于通电状态下时，所述控制组件控制所述遮光组件打开；信号检测器检测到灯体处于断电状态下时，所述控制组件控制遮光组件闭合，遮挡出光端。
进一步的，所述灯体内还设有蓄电池，当灯体处于断电状态时，所述蓄电池为避光系统提供电能。
所述蓄电池与主控制器电连接，当舞台灯内部断电时，主控制器会启动蓄电池，所述蓄电池会继续供电驱动电机和重力传感器，所述重力传感器测定重力方向，并将测定结果传输至主控制器，所述主控制器根据重力方向与灯头方向的夹角调整夹角的角度，实现避光。在光源外接电源时，所述蓄电池会由外接电池实现充电，实现智能控制。
进一步的，所述避光系统还包括用于检测太阳光的太阳光检测器。
所述太阳光检测器主要用于检测到太阳光是否照射到舞台灯上，为了实现更智能的避光保护，可以在灯头上设置太阳光检测器，当检测到太阳光时，且内部光源处于断电状态下时，所述主控制器检测计算灯头方向与重力方向的夹角，并调整夹角至第二夹角的范围，实现避光。
