为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
如图1、2、3、7所示，本申请一些实施例提供一种摄影辅助器材，包括发光组件10、束光组件20和挡光片30，发光组件10上设有用于安装照明灯12的发光区11，束光组件20包括束光筒21和镜片模组22，束光筒21具有入射端21a和出射端21b，束光筒21的入射端21a与发光组件10连接并罩设于发光区11处，镜片模组22安装于束光筒21内并位于入射端21a和出射端21b之间，镜片模组22用于将入射端21a的光线整理后由出射端21b射出并形成光斑40，挡光片30可拆卸地插设于束光筒21上，挡光片30上设有至少一个用于调节光斑40形状的透光辅助孔31。
本申请一些实施例提供的摄影辅助器材，在使用时，发光区11发出的光线由入射端21a射入束光筒21内后，位于束光筒21内的镜片模组22和挡光片30对光线进行共同整理，使得在出射端21b射出的光线形成的光斑40的形状与透光辅助孔31的形状相同；由于挡光片30与束光筒21之间为可拆卸，那么摄影者就可以通过预先准备多种具有不同形状的透光辅助孔31的挡光片30或在一块挡光片30上设置不同形状、大小的透光辅助孔31，使得摄影者在拍摄时，可以根据需要变换不同形状的透光辅助孔31以投射出不同形状的光斑40进行拍摄，使用方便。
在一个实施例中，如图1、2、3、7所示，挡光片30呈长条状，透光辅助孔31设有多个，各个透光辅助孔31沿着挡光片30的长度方向延伸。具体地，使用时，通过使得挡光片30的长度方向与束光筒21的中轴线垂直，并且挡光片30可在束光筒21上沿着垂直于其中轴线的方向移动，从而变换挡光片30上不同位置的透光辅助孔31位于束光筒21内以限制光线射出出射端21b的部分，从而达到利用一 块挡光片30以调节射出不同光斑40的目的，使用方便。
在一个实施例中，透光辅助孔31呈中心对称。具体地，通过将透光辅助孔31设置为中心对称图形，可以利于摄影者定位和拍摄，使用效果好。其中，摄影者可以根据拍摄物体的需要将透光辅助孔31的形状设置为圆形、椭圆形、三角形、矩形、菱形、五角星形、心形、四叶草形或其他特定形状，使用方便、灵活。
在一个实施例中，如图3～5所示，镜片模组22包括投影镜片221和透镜模组223，投影镜片221安装于束光筒21，投影镜片221用于使由入射端21a射入的光线漫反射，透镜模组223安装于束光筒21内并位于投影镜片221和出射端21b之间，挡光片30与投影镜片221贴合设置，挡光片30位于投影镜片221朝向出射端21b的一侧，透镜模组223用于使由透光辅助孔31中通过的光线会聚和整形后由出射端21b射出。具体地，镜片模组22在整理来自入射端21a的光线时，光线进入束光筒21后先射向投影镜片221，此时光线在投影镜片221上发生漫反射以将投影镜片221均匀地照亮，从而使得来自不同方向的光线均在投影镜片221上得到整理和揉和，由于挡光片30贴设在投影镜片221朝向出射端21b的一侧，并且投影镜片221上的光线只能从挡光片30上的透光辅助孔31中通过，从而就使得挡光片30上的透光辅助孔31决定了投影镜片221上投影出去的光斑40形状；光线通过透光辅助孔31后，进一步通过透镜模组223进行整理，以保证各光线组成的光斑40的亮度和形状，光线最后由出射端21b射出，由于该光斑40是投影镜片221通过透光辅助孔31投影成型的，从而使得该光斑40与投影镜片221上的亮度相同且均匀，并且该光斑40的形状与透光辅助孔31的形状相同，从而实现用户可以根据拍摄需要来控制打出来的光斑40的形状，得到边界清晰的理想光斑40，使用效果好。
其中，投影镜片221可以为磨砂玻璃或扩散板等半透明的物件对光线进行漫反射并透过光线。
在一个实施例中，如图3～5所示，镜片模组22还包括挡光圈222，挡光圈222与投影镜片221贴合设置，挡光圈222位于投影镜片221与挡光片30之间，挡光圈222上设有至少一个用于投影的透光孔2221，透光孔2221的横截面大于或等于透光辅助孔31的横截面。具体地，挡光圈222与投影镜片221之间固定连接，如可以 通过双面胶将挡光圈222贴设在投影镜片221的周缘。由于挡光圈222位于投影镜片221与挡光片30之间，光线射向投影镜片221后，光线先通过挡光圈222，此时挡光圈222阻挡部分光线，从而形成一个与挡光圈222上透光孔2221相同的形状的光斑40射向挡光片30，然后，这些光线形成的光斑40在挡光片30的阻挡下，再次得到一个与透光辅助孔31相同形状的光斑40射向镜片模组22，然后该光斑40最后在镜片模组22的整理和聚焦下投射出去，使得摄影者得到一个与透光辅助孔31相同形状且亮度均匀的光斑40。并且，摄影者也可以根据需要，在拍摄时，不使用挡光片30，而是直接利用挡光圈222的作用而得到一个与透光孔2221相同形状的光斑40进行使用，使用灵活、方便。
在一个实施例中，透光孔2221呈中心对称，且透光孔2221的对称中心和透光辅助孔31的对称中心均位于束光筒21的中轴线上，这样可以利于摄影者定位和拍摄，使用效果好。其中，摄影者可以根据拍摄物体的需要将透光孔2221的形状设置为圆形、椭圆形、三角形、矩形、菱形、五角星形、心形、四叶草形或其他特定形状，使用方便、灵活。
在一个实施例中，如图3、5所示，透镜模组223包括聚光透镜2231和光束整形透镜组2232，聚光透镜2231安装于束光筒21上并靠近挡光圈222设置，光束整形透镜组2232安装于束光筒21上并靠近出射端21b设置。具体地，光线在通过透光孔2221和/或透光辅助孔31后，聚光透镜2231先将光线汇聚定焦，以保证光斑40的亮度，然后通过光束整形透镜组2232将光线整理成透光孔2221或透光辅助孔31的形状由出射端21b射出，进而保证投影的光斑40与透光孔2221的形状相同。
在一个实施例中，如图6所示，聚光透镜2231包括环形安装部22311和聚光部22312，环形安装部22311贴设于聚光部22312的周缘，环形安装部22311安装于束光筒21上，聚光部22312位于环形安装部22311朝向光束整形透镜组2232的一侧。具体地，聚光部22312为凸透镜，在安装聚光透镜2231时，先将用于汇聚光线的聚光部22312安装在环形安装部22311上，然后在束光筒21的内壁上设置内螺纹，在环形安装部22311的外周设置外螺纹，将环形安装部22311与束光筒21螺纹连接即可，可以很方便地使得聚光透镜2231安装和拆卸，使用方便。其中，环形安装部22311可以通过双面胶水粘接在聚光部22312的周缘，使得环形安装 部22311的中心在聚光部22312的中轴线上，从而保证光线在聚光部22312上的聚焦效果。
在一个实施例中，如图6所示，聚光部22312与束光筒21之间设有环形垫圈224。具体地，通过在聚光部22312与束光筒21之间设置环形垫圈224，并且使得环形垫圈224呈受挤压状态，这样不仅可以使得聚光部22312被束光筒21更好地支撑，使得聚光部22312安装更加稳定；并且还可以很好地保护聚光部22312，使得聚光部22312和束光筒21的内壁之间具有一定的缓冲，这样即使在束光筒21意外掉落时，由于聚光部22312和束光筒21的内壁之间不是刚性接触，这样外界的冲击力在环形垫片的作用下，可以有效地保护聚光部22312，降低聚光部22312碎裂的风险。
在一个实施例中，如图3、5所示，光束整形透镜组2232包括第一整形透镜22321和第二整形透镜22322，第一整形透镜22321和第二整形透镜22322并排地安装于束光筒21上，第二整形透镜22322靠近第一整形透镜22321朝向出射端21b的一侧设置。具体地，第一整形透镜22321和第二整形透镜22322均为凸透镜，第一整形透镜22321和第二整形透镜22322一起对经过聚光透镜2231作用的光线进行整形，使得各个光线之间组合形成与透光孔2221或透光辅助孔31相同形状的光斑40。
在一个实施例中，如图3、5所示，在第一整形透镜22321和第二整形透镜22322之间设有第一环形支架225，使得第一整形透镜22321和第二整形透镜22322之间具有一定的间隙，避免第一整形透镜22321和第二整形透镜22322之间相互接触造成磨损而影响光线整形效果。并且，第一环形支架225还可以使得第一整形透镜22321和第二整形透镜22322之间安装更加稳固，防止松动，保证光线的整形效果，即保证光斑40的形状不会扭曲。
在一个实施例中，如图3、5所示，束光组件20还包括防护镜片226，防护镜片226安装于束光筒21上并位于出射端21b与第二整形透镜22322之间，防护镜片226用于阻挡外界杂物由出射端21b进入束光筒21内。具体地，防护镜片226设置在最外端，用于保护光束整形透镜组2232，防止外界的杂物划伤第二整形透镜22322；或者防止外界的水分由出射端21b进入束光筒21内而扭曲光束整形透镜组22 32整形的光线，保证光斑40形状的稳定性。其中，防护镜片226的外周与束光筒21之间设有密封圈227，保证密封效果。
在一个实施例中，如图3、5所示，防护镜片226与第二整形透镜22322之间设有第二环形支架228，使得防护镜片226与第二整形透镜22322之间具有一定的间隙，避免防护镜片226与第二整形透镜22322之间相互接触造成磨损而影响第二整形透镜22322对光线整形的效果。并且，第二环形支架228还可以使得第二整形透镜22322安装更加稳固，防止松动，保证光线的整形效果，即保证光斑40的形状不会扭曲。
在一个实施例中，如图3、5所示，聚光透镜2231和光束整形透镜组2232之间设有至少一个用于反射射向束光筒21内壁光线的环形防反射片229。具体地，当光线经过聚光部22312射向光束整形透镜组2232的时候，绝大部分光线在一起形成的主光路在环形防反射片229的中部通过，而部分光线射向束光筒21的内壁，通过在束光筒21的内壁上设置环形防反射片229对射向束光筒21的内壁的光线吸收，即防止射向束光筒21的内壁的光线发生反射，可以有效地防止射向束光筒21的内壁的光线自由反射直至射出出射端21b而造成光斑40边界不清晰的现象发生，使用效果好。
在一个实施例中，如图3、5所示，束光筒21的内壁设有环形卡槽(图未示)，环形防反射片229的外周卡设于环形卡槽内。具体地，在安装环形防反射片229时，通过在束光筒21的内壁上设置环形卡槽，使得环形防反射片229卡设在环形卡槽内，这样可以将环形防反射片229稳定地安装在束光筒21内，防止环形卡槽与束光筒21的内壁之间发生相对滑移，保证环形防反射片229的防反光效果。
在一个实施例中，如图3、5所示，环形防反射片229安装在束光筒21内时与束光筒21的内壁垂直，这样可以具有更好的防反光效果，即阻挡光线的效果。
在一个实施例中，环形防反射片229为黑色薄片。具体地，通过将环形防反射片229选用黑色薄片制作而成，如黑色胶片或具有黑色涂层的不锈钢片等；即利用黑色薄片良好的防反光效果对光线进行吸收；然后利用黑色薄片具有一定的弹性和结构刚性，不仅易于安装至环形卡槽内，而且可以保证环形防反射片229安装至环形卡槽内后具有足够的结构强度与束光筒21的内壁保持垂直对光线进 行阻挡。
在一个实施例中，如图3、5所示，环形防反射片229可以根据需要设置多个，各个环形防反射片229沿着束光筒21的长度方向并排布置，且各个环形防反射片229的中心均在束光筒21的中轴线上，使得各个环形防反射片229在束光筒21的不同位置吸收射向束光筒21内壁的光线，保证光斑40边界清晰。
在一个实施例中，如图1～2所示，发光组件10上设有套接体13，发光区11位于套接体13的末端，束光筒21与套接体13套接。具体地，发光区11的中心位于套接体13的中轴线上，在安装时，摄影者将束光筒21的入射端21a套接在套接体13上，使得束光筒21的中轴线与套接体13的中轴线在同一直线上，保证发光区11发出的光线可以很好地射入束光筒21内，减少光线的损失，摄影者可以通过束光筒21来对照明灯12发出的光线进行约束得到目标形状的光斑40；并且，通过使得束光筒21与套接体13之间以套接的方式连接，还易于束光筒21的安装和拆卸，使用方便。其中，发光组件10包括把持主体14和安装于把持主体14上的电源件，套接体13设于把持主体14上，照明灯12安装于套接体13上，照明灯12与电源件电性连接。
在一个实施例中，如图2～3所示，束光筒21包括光线入射筒体211和安装于光线入射筒体211一端的光线投影筒体212，光线入射筒体211与套接体13套接，入射端21a位于光线入射筒体211上远离光线投影筒体212的一端，出射端21b位于光线投影筒体212上远离光线入射筒体211的一端，投影镜片221、挡光片30和透镜模组223均安装于光线投影筒体212上。具体地，光线入射筒体211的中轴线和光线投影筒体212的中轴线在同一直线上，在将束光筒21安装在套接体13上时，光线入射筒体211与套接体13可拆卸安装；安装好后，发光区11的光线由光线入射筒体211射入，然后经过光线投影筒体212内的各个光学部件处理后，投影出边界清晰的目标形状光斑40供摄影者使用。
在一个实施例中，如图2～3所示，光线入射筒体211包括安装筒体2111，安装筒体2111的一端与光线投影筒体212连接，安装筒体2111的另一端与套接体13套接。具体地，安装筒体2111和套接体13均的横截面均为圆形，在将束光筒21安装在套接体13上时通过安装筒体2111稳固地套接在套接体13的外周，使得束光筒2 1不会相对套接体13随意抖动，使用效果好。其中，安装筒体2111可以为环形橡胶筒体，这样可以利用橡胶具有一定弹性的特性，使得安装筒体2111不仅可以套紧在套接体13上，也易于拆卸下来，并且还易于使得束光筒21相对套接体13旋转，使用方便。
在一个实施例中，如图2～3所示，套接体13上设有环形定位槽131，安装筒体2111上设有至少一个弧形定位体21111，弧形定位体21111与环形定位槽131卡接。具体地，通过在套接体13上设置环形定位槽131，这样在将安装筒体2111套接在套接体13上时，通过持续推动安装筒体2111，使得弧形定位体21111卡入环形定位槽131内，即完成束光筒21的安装。其中，环形定位槽131为在一个平面内的槽体，并使得环形定位槽131的直径与套接体13的中轴线垂直，这样在弧形定位体21111卡入环形定位槽131后，就可以利用弧形定位体21111的辅助定位作用，使得束光筒21在相对套接体13旋转时，束光筒21的中轴线始终与套接体13的中轴线在同一直线上，从而保证光线在束光筒21旋转时不受损失。并且，由于弧形定位体21111与环形定位槽131相互卡接，使得安装筒体2111与套接体13之间连接更加稳固，防止束光组件20由于自重而相对发光组件10倾斜或抖动，保证束光组件20的中轴线与发光组件10的中轴线在同一直线上，使用效果好。
在一个实施例中，如图2～3所示，光线入射筒体211还包括光线过渡筒体2112，光线过渡筒体2112安装于安装筒体2111与光线投影筒体212之间。具体地，光线过渡筒体2112可以根据需要设置一定的长度，这样使得光线由发光区11发出后经过一定距离的揉和，可以使得光线照射在投影镜片221上时混合更加均匀，即使得投影镜片221上的各个位置的光线更加均匀，从而得到的光斑40的亮度也更加均匀。并且，在有多个照明灯12同时朝向投影镜片221射出光线时，通过光线过因出现多个照明灯12的光斑40，而造成通过束光筒21投影的光斑40也不均匀的现象发生。
在一个实施例中，如图2～4所示，束光筒21上设有贯穿束光筒21相对两侧的插接槽213，插接槽213靠近挡光圈222设置并位于挡光圈222朝向出射端21b的一侧，挡光片30插设于插接槽213内。具体地，通过在束光筒21设置插接槽213，使得挡光片30可以通过插接槽213与束光筒21可拆卸安装，使用非常方便。
在一个实施例中，如图2、6所示，插接槽213的侧壁上设有与挡光片30定位的定位凸起214或定位凹槽32；对应地，挡光片30上设有与插接槽213的侧壁定位的定位凹槽32或定位凸起214。具体地，挡光片30在插入插接槽213内时，通过设置在挡光片30和插接槽213的侧壁之间定位凸起214或定位凹槽32进行定位，这样易于帮助摄影者识别插入挡光片30时候插入到了指定位置以进行拍摄，使用方便。
如图1、8、9、10所示，本申请一些实施例还提供一种如上述的摄影辅助器材的使用方法，包括如下步骤：
S001：提供一个发光组件10、一个束光组件20和一个挡光片30，将束光筒21可旋转地安装于发光组件10上，将挡光片30插设于束光筒21上；
S002：打开位于发光区11的照明灯12，使得光线射入束光筒21内，光线经过镜片模组22和透光辅助孔31的整理后由出射端21b射出并形成光斑40；
S003：将束光筒21倾斜一定角度并使得出射端21b朝向目标物，和/或旋转束光筒210°～90°以调节投射至目标物上的光斑40的形状。
本申请一些实施例提供的摄影辅助器材的使用方法，使用时，摄影者可以根据被摄物的形状需要，可以通过将束光筒21倾斜以改变投射到水平面上被摄物的光斑40形状；或者在束光筒21倾斜地情况下再去旋转束光筒21，使得位于束光筒21上的挡光片30一起旋转，这样便改变了挡光片30上的透光辅助孔31与投影镜片221之间的相对形状关系，使得光斑40在透光辅助孔31相对位置发生变化的情况下，光斑40形状也随之改变，达到改变光斑40形状的目的，使用方便。
在一个实施例中，如图9、10所示，执行步骤S003时，若透光辅助孔31呈椭圆形，则在透光辅助孔31的长轴与水平面平行时，此时出射端21b投射出的光斑40的形状呈圆形，并且旋转束光筒21的角度为90°后，光斑40呈拉长状的椭圆形；若透光辅助孔31呈椭圆形，则在透光辅助孔31的长轴与水平面垂直时，此时出射端21b投射出的光斑40的形状呈拉长状的椭圆形，并且旋转束光筒21的角度为90°后，光斑40呈圆形。具体地，通过将带有呈椭圆形透光辅助孔31的挡光片30插入插接槽213内，调节透光辅助孔31的中心与透光孔2221的中心均在束光筒21的中轴线上，这样摄影者就可以在将束光筒21倾斜后，通过旋转束光筒21，得 到在圆形和椭圆形之间变换的光斑40，摄影者可以根据需要使用，不需更换挡光片30，使用方便。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
