附图说明
图1为本公开一个实施例提供的光影屏的结构示意图；
图2为本公开另一个实施例提供的手持支架的结构示意图；
图3为本公开另一个实施例提供的光影屏的轴侧图。
具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图来对本公开提供的光影屏进行详细描述。
如图1所示为本公开一个实施例提供的光影屏的结构示意图，本公开实施例中，光影屏包括：手持支架1、通信模块2、控制模块3以及电源模块4。
其中，在手持支架1上设置有灯板5，灯板5包括：分布有多个显示灯51的显示面。
通信模块用于获取显示信息和指令。
控制模块用于根据通信模块发送的指令控制显示灯显示显示信息。
电源模块用于向显示灯、控制模块以及通信模块供电。
本实施例中，灯板5上设置显示灯51的表面即为上述显示面。
本实施例中，显示灯51可以是LED灯，当然，显示灯51也可以除LED灯以外的其他显示灯，比如LCD灯或OLED灯，只要是便 于与表演者配合且能够显示通信模块所提供的显示信息的显示灯均在本申请的保护范围内。
本实施例中，为了便于表演者进行表演或者操作者进行操作，通信模块2可以是无线通信模块，无线通信模块获取的显示信息和指令可以是集群服务器通过无线信号下发的。显示信息可以包括视频、文字或图像等内容。进一步，通信模块2也可以与控制模块3集成在一起实现对显示灯51的控制。
具体地，灯板5包括印制电路板(Printed Circuit Board，以下简称PCB板)，显示灯51直接焊接在该PCB板的显示面上，即显示灯51自PCB的一侧表面暴露在外面，这样可以达到尽可能地使灯板5轻量化的目的，从而使光影屏更加轻便，方便表演者手持。
可选的，灯板5中设置有多个镂空部52。镂空部52可以是沿灯板5厚度方向的通孔，也可以在灯板5上形成的槽。例如，图1中，多个镂空部52均为PCB板中沿其厚度贯通的通孔，且多个镂空部在显示面上呈矩阵排布。本实施例中，在灯板5中设置多个镂空部可以减轻灯板的重量，进一步，减轻了整个光影屏的重量，便于表演者进行手持操作。
进一步，多个显示灯51设置在显示面上，且呈阵列排布，并且各行显示灯51分别与各相邻两行镂空部52之间的间隔相对应；和/或各列显示灯51分别与各相邻两列镂空部52之间的间隔相对应。例如，在图1中，各行显示灯51分别与各相邻两行镂空部52之间的间隔相对应，这样，既可以保证显示灯51的排布均匀性和排布密度满足要求，又可以使灯板轻量化，从而使光影屏更加轻便，方便表演者手持。在实际应用中，根据镂空部52的形状和排布方式的不同，也可以适应性的改变显示灯51的排布方式。
本公开实施例提供的光影屏，包括：手持支架、通信模块、控制模块以及电源模块；手持支架上设置有灯板，灯板包括分布有多个显示灯的显示面；通信模块用于获取显示信息和指令；控制模块用于根据通信模块发送的指令控制显示灯显示显示信息；电源模块用于向显示灯、控制模块以及通信模块供电。由此，手持支架上的显示面对 显示信息进行显示的同时，便于与表演者的表演结合在一起；进一步，采用通信模块与控制模块对显示灯的显示进行控制，并使用电源模块为显示灯、控制模块以及通信模块供电，为表演者在手持光影屏进行表演时，提供了便利条件。
作为本公开一种可选的方案，如图2所示，手持支架1包括顺次连接的至少两个子支架11，且至少两个子支架中的相邻的两个子支架11可折叠的连接。本实施例中，手持支架1中各可折叠连接的子支架11的设置方式可以使手持支架形成类如三角形、长方形、正方形等形状，配合表演者的表演，实现了显示形式的多样化，为观众提供不一样的舞台表现形式。
进一步，各相邻的两个子支架11连接方式可以有多种形式，比如，各相邻的两个子支架11通过扭簧可折叠的连接，或者各相邻的两个子支架11通过合页可折叠的连接，如图3所示，相邻的两个子支架11通过合页6连接。本实施例中，相邻的两个子支架通过合页连接，结构简单，实现方便。
作为本公开中的一种具体方案，如图3所示，每个子支架11包括：边框111，和与边框111连接且位于边框111内侧的至少一个支撑架112，至少一个支撑架112用于固定通信模块2、控制模块3以及电源模块4。本实施例中，在子支架中设置支撑架，便于对通信模块、控制模块以及电源模块进行固定，本方案采用支撑架独立支撑吃重件，还不会干涉到灯板。
需要说明的是，通信模块2、控制模块3以及电源模块4根据分布需求进行不同的分布，比如，三者同时固定在同一子支架11，当然三者也可以分别固定在不同的子支架11上；或者通信模块与控制模块固定在同一子支架11，而电源模块固定在另一子支架11。参见图3中，通信模块与控制模块集成在一起位于控制盒7中作为一个模组被固定在一个子支架11，而电源模块位于电源盒8中，且电源盒8固定在另一个子支架11。
本公开的一个优选的实施例中，在各相邻的两个子支架11中，在其中一个子支架11的远离灯板5的一侧设置有限位件9，用以限 制相邻的两个子支架11上的灯板5之间的最小夹角。“子支架的远离灯板的一侧”是指子支架在其厚度方向上远离灯板的显示面的一侧。具体地，最小夹角的大小可由限位件9的形状确定。本实施例中，各相邻的两个子支架的任一个子支架远离灯板的一侧设置限位件，既不会影响灯板上显示灯的显示，还可以通过限制相邻的两个子支架的灯板之间的最小夹角，保证子支架远离灯板的一侧上安装的通信模块、控制模块或电源模块等在子支架折叠时不会相互干涉，保证了光影屏操作的安全性。
在本公开另一个优选实施例中，如图3所示，在相邻两个子支架11的远离灯板5的一侧均设置有限位件9，用以通过相邻两个子支架11的上的限位件9相互抵触来限定相邻的两个子支架11上的灯板5之间的最小夹角。具体地，最小夹角的大小可由相邻的两个子支架上限位件9的形状确定。本实施例中，在相邻两个子支架的远离灯板的一侧均设置限位件，既不会干涉灯板，进一步保证了相邻两个子支架中各个子支架的远离灯板的一侧在相邻两个子支架相互折叠时的安全性。
具体地，在图3中，限位件9采用可手提的环状结构。在图3中，相邻两个子支架的远离灯板的一侧均设置有环状结构，两个环状结构在相互抵触时，两个环状结构的弧91相互碰触，可使灯板之间的最小夹角为90°，并且限位件采用可手提的环状结构，可以便于表演者在竖直方向整个提起光影屏，携带光影屏较方便。
进一步，本公开一个优选的实施例中，光影屏还包括：手柄10，手柄10的数量与子支架11的数量相同，且各手柄10一一对应地设置在各子支架11上，且位于远离灯板5的一侧。本实施例中，通过增加手柄，可以使表演者便于对相邻的两个子支架进行握持或折叠。
本公开另一个优选的实施例中，如图3所示，在灯板5中内置有走线(图中未示)，走线用于将各子支架11上的所有显示灯51的线缆引出并汇聚至灯板5的背离显示面的一侧；光影屏还包括：集线盒12，集线盒12的数量与子支架11的数量相同，且各集线盒12一一对应地设置在各子支架11远离灯板5的一侧，用以盛放对应的 子支架11上的所有显示灯51的线缆。显示灯51的线缆由灯板5远离显示面的一侧进入集线盒12，由集线盒12出来的显示灯51的线缆与控制模块3连接，以便控制模块3通过显示灯51的线缆实时控制显示灯51显示显示信息。本实施例中，灯板中内置走线将显示灯的线缆引出并汇聚至灯板的背离显示面的一侧，保证了显示灯的显示面的整洁性；进一步，集线盒可以为封闭的盒体，通过在子支架远离灯板的一侧设置集线盒，放置显示灯的线缆，再次保证了光影屏外观的整洁。
进一步，本公开另一个优选的实施例中，如图3所示，在各集线盒12上设置有收纳筒13，收纳筒13用于插表演道具，表演道具可以是旗帜、扇子等物体。图3中收纳筒13的形状为圆柱状，便于插入表演道具。当然，收纳筒13还可以是其他便于表演道具插入的形状，对此，本申请不做限定。
进一步，在图3所示的实施例中，光影屏还包括：复位开关14，复位开关14与控制盒7连接，用于控制控制盒7中控制模块3的复位。
综上所述，本公开提供的光影屏，手持支架上设置灯板，灯板包括分布有多个显示灯的显示面，便于表演者手持且可以实时显示通信模块获取到的显示信息。手持支架包括顺次连接的至少两个子支架，各相邻的两个子支架可折叠的连接，便于对手持支架进行折叠，形成表演节目中需要的形状。进一步，在各相邻的两个子支架中，其中一个子支架的远离灯板的一侧设置限位件，或者相邻两个子支架的远离灯板的一侧均设置限位件，保证了子支架在折叠时远离灯板一侧的安全性。进一步，光影屏还包括一一对应地设置在各子支架上的手柄，便于表演者对各子支架进行折叠。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
