Description

一种直照式和柔光式转动变换的拍摄用LED照明灯 技术领域
本发明涉及照相或摄像用照明装置，特别是一种直照式和柔光式可通过转动变换的拍摄用LED照明灯。适合作为连接在照相机或摄像机上的照明灯。
背景技术
目前普遍使用的拍摄用LED照明灯，结构形式可分为直照式和柔光式二类：其中直照式拍摄用LED照明灯有如本申请人在先申请的中国专利第201120502007.5号的“一种可拼接的摄像用LED型照明灯”，是将若干LED光源向前直照方式安装排列在灯壳体的发光窗口内的电路板上。这种LED型照明灯的光线照射距离可以较远，但光线比较刺目。柔光式拍摄用LED照明灯有如本申请人在先申请的中国专利第201320017274.2号的“一种摄影或摄像用的LED照明灯”，是在灯壳体的发光窗口内侧处安装有一片以其正面覆盖着发光窗口的塑料导光板，将若干LED光源以向塑料导光板侧面直照的方式排列在塑料导光板侧面的外侧四周。这种LED型照明灯的光线柔和、不刺眼，但照射距离较近，比直照式拍摄用LED型照明灯的光线照射距离要短。
上述二类拍摄用LED型照明灯各有所长，照射距离较远的拍摄场合往往需要使用直照式拍摄用LED照明灯才能达到理想的照明效果；照射距离较近的拍摄场合(特别是有人物的场合)往往需要使用柔光式拍摄用LED照明灯才能达到理想的照明效果。如果拍摄者外出照相或摄像时既需要携带直照式拍摄用LED照明灯，又需要携带柔光式拍摄用LED照明灯，那是很麻烦的事。
为此，本申请人在先申请了中国专利申请第201610007562.8号的一种直照式和柔光式可变换的拍摄用LED照明灯，使得拍摄者外出照相或摄像时仅携带一个照明灯便既可作为直照式拍摄用LED照明灯使用，又可作为柔光式拍摄用LED照明灯使用。其结构包括一个灯壳体、安装在灯壳体内的若干LED光源、设置于灯壳体上的电源连接器和电源开关、设于灯壳体外的连接支架，其中灯壳体正面设有发光窗口，所述发光窗口内侧正面的灯壳体上安装排列有若干正面LED光源，正面LED光源的照射方向朝向LED照明灯前方，所述发光窗口内侧四周侧面的灯壳体上安装排列有若干侧面LED光源，所述发光窗口内侧在所述正面LED光源前方的灯壳体上安装有一片覆盖所述发光窗口的透明导光板，所述 侧面LED光源的照射方向分别朝向所述透明导光板的四周侧面，所述透明导光板对着正面LED光源的朝内表面上均布有光线反射凹坑，灯壳体上还设置有照明方式转换开关。但这一方案的缺点是：由于透明导光板挡在正面LED光源的前面，因此导致正面LED光源的直照式光照亮度有一定损失，无法最充分发挥出直照式光照亮度；另一方面，由于透明导光板的背面必须具有高度透明性，其上的光线反射凹坑的设置方式受到一定限制，因此也导致侧面LED光源的折射向前方的光照亮度有一定损失，无法最充分发挥出柔光式光照亮度。
另外，目前已有的所有拍摄用LED照明灯，基本结构都是灯体只有前侧面设置发光窗口，灯体后侧面为灯体壳座，电池座、电源开关、调光器等都设置在灯体壳座上，电路板设置在灯体壳座内。
发明内容
为了克服本申请人在先申请专利的直照式和柔光式可变换的拍摄用LED照明灯存在直照式或柔光式光照亮度都有一定损失、无法最充分发挥出光照亮度的缺陷，本发明的目的是提供一种改进的直照式和柔光式转动变换的拍摄用LED照明灯，可以克服现有技术的缺陷。

上述技术方案所述支架是灯座的支撑部分，其可以是带有外连接端的连接支架，也可以是不带有外连接端的支架、如带有手把、撑杆或绑带等的支架。所述连接支架的连接端可以是热靴式插头或热靴式插座。所述支架上还可以设有各种合适结构的转动关节，用以调节照明灯的照射角度。
上述技术方案所述照明方式转换开关可以是设置在所述发光主体和所述灯座之间的自动感应电子开关或机械式行程开关，使到当所述发光主体的前侧面或后侧面被转动至朝向照明灯前方且到位时，这个侧面上的发光窗口内侧的所属LED光源便自动得电发光，而被转动至朝向照明灯后方的侧面上的发光窗口内侧的所属LED光源便自动失电熄灭。
上述技术方案所述正面LED光源板的LED光源可以采用带有凸透镜的LED光源，所述侧面LED光源板上的LED光源可以采用不带凸透镜的LED光源。所 述带有凸透镜LED光源就是指LED光源的发光面前侧设有一聚光用的凸透镜、LED光源的半值角较小，如插件式LED灯珠；所述不带凸透镜LED光源就指是LED光源的发光面前侧没有设置聚光用的凸透镜、LED光源的半值角较大，如普通贴片式LED。
上述技术方案所述电源可以是电池、安装电池的电池座、接入外电源的插座或接入外电源的带插头外引导线等。
本发明的有益效果：由于将灯体分拆为转动配合在一起的发光主体和灯座二个独立部分，在发光主体的前侧面和后侧面上均各设有发光窗口，其中一个发光窗口设置为直照式照明、另一个发光窗口设置为柔光式照明，然后由灯座与拍摄机器作不能转动的固定连接、如热靴式插接连接，所以这样一个照明灯便可固定连接在照相机或摄像机上后，通过转动发光主体进行变换，既能够为拍摄前方提供直照式照明，也能够为拍摄前方提供柔光式照明；由于照明灯上的直照式光源前方再不用遮挡一个导光板，所以直照式光照亮度不会损失，可以最充分发挥出直照式光照亮度；由于导光板的后侧面再不需要高度透明，所以设置光线反射凹坑可以比较密集，也可以印刷上密集反射点，使到向前方折射的光照亮度不会损失，可以最充分发挥出柔光式光照亮度。

具体实施方式
参照图1～图2，本直照式和柔光式转动变换的拍摄用LED照明灯，其特征是：包括灯座1、发光主体2和支架3，所述发光主体2的底部与所述灯座1的顶部转动配合，连接支架3设置在灯座1底部，所述发光主体2由主体壳4、正面LED光源板5、侧面LED光源板6和导光板7组成，主体壳4的前侧面8和后侧面9上均各设有发光窗口10、11，其中一个发光窗口10内侧正面安装着覆盖发光窗口10的所述正面LED光源板5、所述正面LED光源板5上安装有若干照射方向朝向所在发光窗口10前方的LED光源12等，另一个发光窗口11内侧正面安装着覆盖发光窗口10的所述导光板7、所述侧面LED光源板6安装在所述导光板7外侧、且所述侧面LED光源板6上安装有若干照射方向朝向所述导光板侧面13的LED光源14等，所述灯座1上设置有电池座15、电源开关16和调光器17和照明方式转换开关(未示出)，所述灯座1内安装有电路板18，所述正面LED光源板5的电源端和侧面LED光源板6的电源端分别与所述电池座15、电源开关16、调光器17、照明方式转换开关和电路板18作对应的电连接。
另外，所述正面LED光源板5的电源端和侧面LED光源板6的电源端的连接导线是通过所述发光主体2与所述灯座1转动配合的转轴19的中心孔20进入所述灯座1内。
所述发光主体2和所述灯座1之间设置有同向转动限制在180°内的限位结构，以防止所述发光主体2与所述灯座1的转轴19中心孔20内的连接导线产生缠绕。如图7所示，同向转动限制在180°内的限位结构具体是在所述发光主体2底面上设置限位钉21和22、在所述灯座1顶面上设置限位卡座23和24。
所述限位卡座23和24上还分别设有限位钉21和22的定位凹坑25、26、27、28。
所述侧面LED光源板6是分别安装在所述导光板7的四个侧面的外侧主体壳4上。所述导光板7和所述侧面LED光源板6安装固定在主体壳4上，且是安装在主体壳4上的一个散热座29上。
所述支架3为带有外连接端30的连接支架，所述连接支架的外连接端30是热靴式插头。所述支架3上还设有转动关节31。
所述照明方式转换开关是设置在所述灯座1上的自动感应电子开关，当所述发光主体2的前侧面8或者后侧面9被转动至朝向照明灯前面并到位时，这个前侧面8或者后侧面9上的发光窗口10或者11内侧的所属LED光源便自动得电发光，而被转动至朝向照明灯后面的后侧面9或者前侧面8上的发光窗口11或者10内侧的所属LED光源便自动失电熄灭。
所述调光器17包括了光照亮度调节旋钮和光照色温调节旋钮。
所述电池座15、电源开关16和调光器17是设置在所述灯座1上的后侧面。
所述正面LED光源板5上的LED光源12采用直插灯珠型的LED光源，所述侧面LED光源板6的LED光源14贴片型的LED光源。
使用上，当照明灯处于图1、图2状态时，在电池座15上安装了电池并接通电源开关16后，照明方式转换开关(未示出)便自动控制发光主体2的前侧面8的发光窗口10内侧正面的正面LED光源板5上的LED光源12等发光，为照明灯前方提供直照式照明，通过调光器17可以调节光照亮度和光照色温至适用程度，这时限位钉21配合在限位卡座23上的定位凹坑25内、限位钉22配合在限位卡座24上的定位凹坑26内而使发光主体2得到定位，由于限位钉21和22受到定位凹坑25和26前方的卡座凸块的阻挡限位，使发光主体2不能再顺时针转动。当照明灯前方需要提供柔光式照明时；如图3所示逆时针转动发光主体2，限位钉21和22便分别退出定位凹坑25和26且离开限位卡座23和24，转动至发光主体2的前侧面8朝向照明灯后方而发光主体2的后侧面9朝向照明灯前方时，即为图4状态，照明方式转换开关(未示出)便自动控制发光主体2的后侧面9的发光窗口11内侧正面的导光板7外侧的侧面LED光源板6上的LED光源14等发光，光线通过导光板7折射后为照明灯前方提供柔光式照明；同时，照明方式转换开关(未示出)自动控制这时朝向照明灯后方的发光主体2的前侧面8的发光窗口10内的正面LED光源板5上的LED光源12等熄灭；这时限位钉21配合在限位卡座24上的定位凹坑28内、限位钉22配合在限位卡座23上的定位凹坑27内而使发光主体2得到定位，由于限位钉21和22受到定位凹坑28和27前方的卡座凸块的阻挡限位，使发光主体2不能再逆时针转动，即发光主体2只能逆时针转动到180°为止，如果这时要转动发光主体2变换发光主体2的前侧面8朝向照明灯前方，发光主体2也只能顺时针转动到180°为止，这就是所谓同向转动限制在180°内。
