Description

摄影辅助装置 技术领域
本申请涉及摄影器材技术领域，具体涉及一种摄影辅助装置。
背景技术
造型灯是用于拍摄前把灯光打开，使得灯光照到被摄物上，从而让摄影师调节灯光打到被摄物上的角度和效果。相关技术中，造型灯的光源一般跟拍摄的闪光管不是同一个光源，而由于主摄的闪光管已经占用了最理想的中心位置，使得造型灯的光源只能放到位于闪光管的周边，这样，在使用束光筒时，造型灯产生的灯光效果与拍摄时的闪光会有偏差，即造型灯通过束光筒打出的光斑不能与闪光管通过束光筒打出的灯光重合，使得用户不能准确定位拍摄物上所需拍摄的位置。

问题的解决方案
技术解决方案
为解决上述技术问题，本申请实施例采用的技术方案是：提供了一种摄影辅助装置，包括发光组件和束光组件，所述发光组件上设有发光区，所述发光区内设有闪光灯和至少一个LED灯，所述束光组件包括束光筒和镜片模组，所述束光筒具有入射端和出射端，所述镜片模组安装于所述束光筒内并位于所述入射端和所述出射端之间，所述束光筒的入射端与所述发光组件连接并罩设于所述发光区处，所述镜片模组用于将所述入射端的光线投射至所述出射端射出。
本申请实施例提供的摄影辅助装置的有益效果在于：由于在束光筒内设有镜片模组，镜片模组将入射端的光线整理后统一由出射端射出，即镜片模组可以将来自不同方向的光线进行整理然后朝向出射端的同一方向射出，从而保证来自 不同方向的光线由出射端射出后始终是重合的。那么在使用时，摄影者先打开LED灯，使得LED灯的光线射向镜片模组并经过镜片模组处理后形成光斑由出射端投射至目标位置，以对准拍摄物体的目标位置；然后摄影者按动快门的时候，来自快门的光信号便触发闪光灯闪光，此时闪光灯的闪光范围便准确地与LED灯投射的光斑重合，从而使得摄影者准确地拍摄物体的目标位置，使用效果好。

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、5所示，本申请一些实施例提供一种摄影辅助装置，包括发光组件10和束光组件20，发光组件10上设有发光区11，发光区11内设有闪光灯12和至少一个LED灯13，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，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，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用于将入射端21a的光线投射至出射端21b射出。
本申请一些实施例的摄影辅助装置，由于在束光筒21内设有镜片模组22，镜片模组22将入射端21a的光线整理后统一由出射端21b射出，即镜片模组22可以将来 自不同方向的光线进行整理然后朝向出射端21b的同一方向射出，从而保证来自不同方向的光线由出射端21b射出后始终是重合的。那么在使用时，摄影者先打开LED灯13，使得LED灯13的光线射向镜片模组22并经过镜片模组22处理后形成光斑30由出射端21b投射至目标位置，以对准拍摄物体的目标位置；然后摄影者按动快门的时候，来自快门的光信号便触发闪光灯12闪光，此时闪光灯12的闪光范围便准确地与LED灯13投射的光斑30重合，从而使得摄影者准确地拍摄物体的目标位置，使用效果好。
在一个实施例中，如图5～7所示，镜片模组22包括投影镜片221、挡光圈222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，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朝向出射端21b的一侧，挡光圈222上设有至少一个用于投影的透光孔2221，透镜模组223安装于束光筒21内并位于挡光圈222和出射端21b之间，透镜模组223用于使由透光孔2221中通过的光线整理和整形后由出射端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，由于挡光圈222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圈222上的透光孔2221中通过，从而就使得挡光圈222上的透光孔2221决定了投影镜片221上投影出去的光斑30形状；光线通过透光孔2221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30的亮度和形状，光线最后由出射端21b射出，由于该光斑30是投影镜片221通过透光孔2221投影成型的，从而使得该光斑30与投影镜片221上的亮度相同且均匀，并且该光斑30的形状与透光孔2221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30的形状，得到边界清晰的理想光斑30，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5～7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后，聚光透镜2231先将光线汇聚定焦，以保证光斑30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的形状由出射端21b射出，进而保证投影的光斑30与透光孔2221的形状相同。
在一个实施例中，如图5～6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5～6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5、7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安装于束光筒21上，第二整形透镜22322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相同形状的光斑30。
在一个实施例中，如图5、7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30的形状不会扭曲。
在一个实施例中，如图1、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2232整形的光线，保证光斑30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30的形状不会扭曲。
在一个实施例中，如图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30边界不清晰的现象发生，使用效果好。
在一个实施例中，如图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，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5所示，环形防反射片229设有多个，各环形防反射片229并排布置于束光筒21内。具体地，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30边界清晰。
在一个实施例中，如图2所示，闪光灯12位于发光区11的中部，LED灯13设有两个，两个LED灯13对称地设于闪光灯12的两侧。具体地，由于上述镜片模组22对光线的聚焦和整形的作用，使得闪光灯12在束光筒21内的光线损失很小，那么在使用时，闪光灯12的功率就可以做得比较小即可实现拍摄目的，从而使得闪光组件可以整体做得比较小巧，易于携带。其中，闪光灯12呈长条状，通过将两个LED灯13对称地设置在闪光灯12长度方向的两侧，这样可以尽可能地使得两个LED灯13靠近闪光灯12的中心位置，从而使得两个LED灯13投射出的光斑30亮度更加均匀和采光适合拍照。
在一个实施例中，如图2所示，闪光灯12位于发光区11的中部，LED灯13设有多个，各个LED灯13以闪光灯12的中心为对称中心分布于闪光灯12的外周。具体地，根据需要，LED灯13可以设置多个，通过使得各个LED灯13以闪光灯12的中 心为对称中心分布于闪光灯12的外周，这样尽可能地使得各个LED灯13靠近闪光灯12的中心位置，从而使得各个LED灯13投射出的光斑30更加均匀和亮度适应拍摄环境的光斑30。
在一个实施例中，如图1～2所示，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，把持主体14上设有套接体141，发光区11位于套接体141的末端，闪光灯12和LED灯13均安装于套接体141上，闪光灯12和LED灯13均与电源件电性连接，束光筒21与套接体141的末端套接并罩设于发光区11上。具体地，发光区11的中心位于套接体141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141上，使得束光筒21的中轴线与套接体141的中轴线在同一直线上，保证反光区发出的光线可以很好地射入束光筒21内，减少光线的损失。并且，通过使得束光筒21与套接体141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。
在一个实施例中，如图2所示，套接体141的外表面设有供束光筒21套接的倾斜引导面。具体地，通过在接体141的外表面设有供束光筒21套接的倾斜引导面，使得套接体141的横截面沿着朝向发光区11一端的方向逐渐减小，即套接体141的外周在中轴线方向上是倾斜的，这样束光筒21在套接在套接体141上时，就可以轻松地套设在套接体141的外周，并且在持续推进的过程中直至卡紧即安装到位，安装方便。
在一个实施例中，如图1～2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141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、挡光圈222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141上时，光线入射筒体211与套接体141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30供摄影者使用。
在一个实施例中，如图1～2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141套接。具体地，在将束光筒21安装在套接体141上时通过安装筒体2111稳固地套接在套接体141上，使得束光筒21不会相对套接体141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141上，也易于拆卸下来，使用方便。
在一个实施例中，如图2、图3所示，套接体141上设有环形定位槽1411，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1411卡接。具体地，通过在套接体141上设置环形定位槽1411，这样在将安装筒体2111套接在套接体141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1411内，即完成束光筒21的安装；并且，由于弧形定位体21111与环形定位槽1411相互卡接，使得安装筒体2111与套接体141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1～2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30的亮度也更加均匀。并且，在有多个LED灯13同时朝向投影镜片221射出光线时，通过光线过渡筒体2112的设置，可以使得各个LED灯13之间的光线柔和在一起，避免投影镜片221上出现多个LED灯13的光斑30，造成通过束光筒21投影的光斑30也不均匀的现象发生。
在一个实施例中，如图1、6所示，束光筒21上设有用于插接挡光片(图未示)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。具体地，挡光片上设有多个规格不同的透光辅助孔，即使得光线在经过投影镜片221后最终投射出的光斑30的形状是透光辅助孔的形状，这样摄影者在使用时，就可以根据需要将挡光片插入插接槽213内，使得透光辅助孔的中心在 束光筒21的中轴线上，以借助挡光片的作用得到目标规格的光斑30打到被摄物体上，使用方便。
在一个实施例中，插接槽213的侧壁上设有用于与挡光片定位的定位凸起或定位凹槽。具体地，挡光片在插入插接槽213内时，通过设置定位凸起或定位凹槽，这样易于帮助摄影者识别挡光片时候插入到了指定位置以进行拍摄，使用方便。
在一个实施例中，透光孔2221呈中心对称。具体地，通过将透光孔2221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，透光孔2221设有多个，且多个透光孔2221分布于投影镜片221上。具体地，透光孔2221也可以根据拍摄的需要设置多个，各个透光孔2221可以规则分布，也可以无规则分布，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。
