以下将结合附图通过几个实施例对摄影摄像用灯的结构进行详细说明。
摄影摄像用灯的第一实施例。
参阅图1至图4,本申请一实施例提供一种摄影摄像用灯100,该摄影摄像用灯100可以为闪光灯、摄影补光灯、舞台照明灯、直播用灯等。本实施例的摄影摄像用灯100包括主体10和设置在主体10 上的灯头20。该灯头20包括壳体21、光源22、光效透镜23以及隔热件24。
其中,壳体21内部设有容置腔212,壳体21的一端设有与容置腔212连通的开口211。光源22设置在壳体21的容置腔212中,该光源22可以包括闪光灯灯管和COB灯。光效透镜23设置在壳体21的开口211处,并与光源22处于同一光轴上。隔热件24呈透明设置,隔热件24设于光源22与光效透镜23,用于阻隔光源22向光效透镜23发出热量。
本实施例的摄影摄像用灯100中,当光源22所发出的热量到达隔热件24后,隔热件24将热量进行迅速的吸收,并使得热量能在隔热件24中均匀地散发,避免其局部区域过热。因光源22所发出的热量通过隔热件24的阻隔和对外的均匀散发,部分热量能通过壳体21等部件传导到外界,从而有效地防止因光效透镜23中局部区域过热而造成热损坏。
在本实施例中,隔热件24将壳体21的容置腔212分隔成第一容置区2121和第二容置区2122。其中,光源22设置在第一容置区2121,光效透镜23设置在第二容置区2122,隔热件24用于阻隔第一容置区2121中的热量进入第二容置区2122。
本实施例的主体10的内部设有控制器,用于实现对摄影摄像用灯100内部相关功能部件及结构部件的控制。主体10的底部设有热靴30,主体10及灯头20可以通过热靴30整体安装在相机等摄像设备上,从而使摄影摄像用灯100与相机等设备建立电信号连接。灯头20可转动地设置在主体10上,灯头20可绕主体10进行水平和上下摆动,以扩大摄影摄像用灯100的补光范围。
在本实施例中,灯头20的壳体21一端与主体10可转动地连接,灯头20的另一端开设有开口211。灯头20的内部设有容置腔212,灯头20的开口211与容置腔212连通。
本实施例的壳体21包括上壳体213和下壳体214,上壳体213和下壳体214的内部均形成有腔体。上壳体213扣合在下壳体214的上方,以使上壳体213的腔体和下壳体214的腔体构成壳体21内部的容置腔212。
灯头20还包括支架250和反光罩251,支架250和反光罩251均设置在壳体21的容置腔212中。本实施例的反光罩251设置在支架250的一端,反光罩251朝向壳体21的开口211的表面设有安装槽2511,光源22设置在安装槽2511的内部。
在本实施例中,反光罩251的整体外轮廓呈C形,反光罩251中的安装槽2511呈弧形,且该安装槽2511的槽口呈方形。在其他示例中,反光罩251及安装槽2511的形状还可以根据使用需求设计成其他形状,如圆形、L形等,在此不作过多地限定。
光源22安装在反光罩251的安装槽2511中,光源22发出的光线可由安装槽2511的槽口射出,而射向光效透镜23。
灯头20还包括屏蔽罩26,屏蔽罩26设置在安装槽2511的槽口处,以固定在安装槽2511上。屏蔽罩26的外轮廓适配槽口而设置成方形,屏蔽罩26对应安装槽2511的槽口设有贯通的方形的罩口261。通过安装槽2511的槽口和屏蔽罩26的罩口261,光源22可以将闪光光线射向光效透镜23。
本实施例的支架250和屏蔽罩26可以采用耐热材料制成,如陶瓷,以使支架250和屏蔽罩26能够耐高温,避免摄影摄像用灯100在工作时频繁发光会产生大量的高温对支架250和屏蔽罩26造成损伤,保证二者结构的稳定性。
在本实施例中,灯头20还包括驱动组件27,驱动组件27设置在壳体21的容置腔212中。驱动组件27包括驱动电机271、与驱动电机271相连的丝杆272以及可移动地设置在丝杆272上的螺母273。
驱动组件27靠近壳体21的顶部设置,丝杆272沿壳体21的轴线延伸。螺母273螺接套设在丝杆272上,支架250背离反光罩251的一端与螺母273固定。丝杆272的一端与驱动电机271连接,在驱动电机271的作用下,丝杆272能够沿其自身的轴线转动,以使螺母273能够沿丝杆272的轴线方向移动,使得支架250能够直线移动,从而使光源22能够靠近或者远离光效透镜23,以实现调焦的目的。
本实施例的灯头20还包括风扇28,风扇28设置在壳体21的容置腔212中,且靠近壳体21的内部设置。壳体21的下壳体214对应风扇28的位置处开设有进风口215。风扇28设置在支架250的反 光罩251的下方,且风扇28的出风面朝向光源22、支架250以及光效透镜23。
风扇28工作时,外部环境的风能够通过进风口215进入容置腔212中。风扇28朝向光源22、支架250以及光效透镜23吹风,以产生温度较低的气流。温度较低的气流能够与光源22工作时产生的高温混合,以降低壳体21内部的温度,防止壳体21内部部件因温度过高发生软化变形的情况。
进一步地,壳体21的开口211处设有光效透镜23,该光效透镜23包括菲涅尔镜片231和扩散片232。其中,扩散片232设置在壳体21的开口211处并封闭壳体21的开口211。菲涅尔镜片231布置在扩散片232面向光源22的一侧,该菲涅尔镜片231与光源22正对设置。菲涅尔镜片231与扩散片232相配合,实现闪光光线的扩散。
在本实施例中,灯头20还包括固定柱29,固定柱29固定在壳体21设有开口211的端面上且沿壳体21的轴线延伸至壳体21的内部。固定柱29设有多个,多个固定柱29沿灯头20开口211的周缘间隔布置。本实施例的菲涅尔镜片231和扩散片232的外周边缘均设有固定柱29,以使扩散片232和菲涅尔镜片231能够卡接固定在固定柱29上,从而使菲涅尔镜片231和扩散片232安装在壳体21的开口211处。
本实施例的固定柱29设有四个,其中两个固定柱29设置在上壳体213上,另外两个固定柱29设置在下壳体214上。在装配时,可以在上壳体213和下壳体214结合之前,先完成固定柱29在上壳体213、下壳体214上的安装。然后可以通过固定柱29使菲涅尔镜片231和扩散片232卡在下壳体214的固定柱29上,再将上壳体213扣合连接在下壳体214的上方,以完成壳体21和光效透镜23的装配。
在其他示例中,固定柱29可以为螺柱,壳体21开口211处的端面上设有与该螺柱相适配的螺孔。在装配时,可以将光效透镜23整体安装在壳体21上。具体地,在完成上壳体213和下壳体214的连接后,将菲涅尔镜片231和扩散片232置于壳体21开口211处的端面上,使固定柱29和螺孔相对应,再将螺柱对应螺接在螺孔中,使螺柱的螺帽压紧扩散片232的边缘,从而使光效透镜23安装在壳体21上。
在本实施例中,灯头20还包括定位凸起217。定位凸起217凸设在壳体21的内壁上且靠近壳体21的开口211设置,该定位凸起217设置在下壳体214上。在其他示例中,定位凸起217还可以设置在上壳体213上。
本实施例的菲涅尔镜片231的边缘设有固定卡口2311,菲涅尔镜片231的固定卡口2311能够与定位凸起217卡接配合。在装配时,通过固定卡口2311与定位凸起217的配合,可实现菲涅尔镜片231在壳体21上快速定位,提高菲涅尔镜片231在壳体21上的装配精度和装配效率。
进一步地,灯头20还包括隔热件24,隔热件24呈透明设置。该隔热件24设于光源22与光效透镜23之间,用于阻隔光源22向光效透镜23发出的热量。
在本实施例中,隔热件24设置在反光罩251的安装槽2511的槽口处,且布置在在光源22面向光效透镜23的一侧。该隔热件24适配安装槽2511的槽口设置成方形,隔热件24通过屏蔽罩26压紧在安装槽2511的槽口处。
其中,容置腔212中隔热件24与反光罩251围合的部分构成第一容置区2121,容置腔212中除第一容置区2121之外的部分构成第二容置区2122。
隔热件24由隔热材料制成,如隔热玻璃等。将隔热件24设置在反光罩251的安装槽2511的槽口处,使隔热件24能够对安装槽2511中的光源22直接产生隔热作用,以使隔热件24在闪光光线发射的起点位置即能进行热量的阻隔,避免高温热量在壳体21的容置腔212内聚集,从而防止高温对光效透镜23产生热熔损伤,保证摄影摄像用灯100的结构稳定性和用户的使用体验。该隔热件24呈透明设置,能够使摄影摄像用灯100的闪光光线顺利通过,在隔热的同时,保证摄影摄像用灯100的补光效果。
在其他一些示例中,该隔热件24可以设置多个,多个隔热件24可以在反光罩251的安装槽2511的槽口处形成多重保护,进一步地加强壳体21内部以及光源22与光效透镜23之间的隔热效果。
本实施例的摄影摄像用灯100可以通过主体10底部的热靴30安装在相机的顶部,以实现对摄像 环境的补光或者配光。该摄影摄像用灯100也可以单独放置,无需与相机固定,而通过无线连接方式与相机进行电信号连接,以实现补光或者配光。
本实施例的摄影摄像用灯100在使用时,光源22发出的光依次通过隔热件24、菲涅尔镜片231以及扩散片232后从灯头20中射出。隔热件24设置在反光罩251上,以与反光罩251围合形成一个封闭的第一容置区2121。隔热件24能够光源22散发的热量阻隔在第一容置区2121中,结合设置在第二容置区2122的风扇28,由第一容置区2121溢到第二容置区2122的热量也能够迅速被排放至壳体21的外部,从而有效地防止第二容置区2122因温度过高而造成的光效透镜23的损伤。
摄影摄像用灯的第二实施例。
参阅图5至图7,第二实施例的摄影摄像用灯100与第一实施例的摄影摄像用灯100的结构大致相同,本实施例的摄影摄像用灯100也包括主体10和设置在主体10上的灯头20,灯头20包括壳体21、光源22、光效透镜23、隔热件24。其中,灯头20可转动地设置在主体10上,光源22通过反光罩251设置在壳体21的容置腔212中。反光罩251与支架250连接,支架250通过动力组件能够实现直线移动,以使灯光能够靠近或者远离光效透镜23。光效透镜23包括菲涅尔镜片231和扩散片232,二者的在壳体21上的安装方式与第一实施例相同,在此不再赘述。此外,灯头20还包括风扇28,风扇28的设置方式与第一实施例相同,用于实现灯头20内部的降温。
第二实施例的摄影摄像用灯100与第一实施例的摄影摄像用灯100的差别之处在于:本实施例中的隔热件24设置在壳体21的开口211处,且布置在光效透镜23面向光源22的一侧。即本实施例的隔热件24设置在壳体21的开口211处,并布置在菲涅尔镜片231面向光源22的一侧。
在本实施例中,隔热件24将壳体21的容置腔212分隔成第一容置区2121和第二容置区2122。其中,光源22设置在第一容置区2121,光效透镜23设置在第二容置区2122,隔热件24用于阻隔第一容置区2121中的热量进入第二容置区2122。
其中,容置腔212中隔热件24面向光源22的一侧构成第一容置区2121,容置腔212中隔热件24面向光效透镜23的一侧构成第二容置区2122。
在本实施例中,隔热件24外形与壳体21的开口211形状相适配。隔热件24的周侧边缘设有连接口244,连接口244设有多个,多个连接口244与壳体21上的多个固定柱29一一对应地卡接配合。通过连接口244与固定柱29的卡接配合,使隔热件24能够固定在壳体21的开口211处。在其他示例中,隔热件24还可以通过其他方式固定在壳体21的开口211处,如粘接、热熔连接等。
本实施例的隔热件24的周侧边缘还设有定位卡口245,隔热件24的定位卡口245能够与壳体21内壁上的定位凸起217卡接配合。在装配时,通过定位卡口245与定位凸起217的配合,可以实现隔热件24在壳体21上的快速定位,保证隔热件24在壳体21上的装配精度和装配效率。
隔热件24呈透明设置,以保证摄影摄像用灯100发出的闪光光线能够顺利通过隔热件24而射向光效透镜23。该隔热件24由隔热材料制成,如隔热玻璃等。
在本实施例中,隔热件24设置在壳体21的开口211处,该隔热件24靠近光效透镜23设置,使得隔热件24能够直接在光效透镜23朝向光源22的一面实现隔绝高温热量的效果,以使隔热件24对光效透镜23进行全面且直接的保护,避免或降低高温热量与光效透镜23的接触而对光效透镜23产生热熔损伤,保证摄影摄像用灯100的结构稳定性和用户的使用体验。
在其他一些示例中,该隔热件24可以设置多个,多个隔热件24可以在壳体21的开口211处形成多重保护,进一步地加强光源22与光效透镜23之间的隔热效果。
在另一示例中,隔热件24除了设置在壳体21的开口211处之外,还可以设置在壳体21内部的其他区域,只要布置在光源22和光效透镜23之间即可,该隔热件24的外侧壁与壳体21的内侧壁连接固定。
此外,如图8和图9所示,在其他示例中,灯头20还包括硅胶圈204。硅胶圈204为圈状结构,该硅胶圈204的外形与隔热件24的外轮廓相适配,圈状结构的硅胶圈204套设在隔热件24的外周侧边缘,二者共同设置在壳体21的开口211处。
硅胶圈204的外周与壳体21的内壁相抵接,以将隔热件24上的热量传递至壳体21。在本示例中,可以将壳体21设计成金属材质,以更好地实现热量的传递而进行散热,也可以在壳体21与硅胶圈204的连接处设置金属散热件,通过金属散热件将隔热件24上的热量散出。
如图10和图11所示,在本实施例的另一示例中,可以将隔热件24设置成部分遮挡光效透镜23的菲涅尔镜片231的形式,并使隔热件24与菲涅尔镜片231的中心部位相对应。
具体地,该示例中的隔热件24整体呈长条形,其外轮廓包括一对相对设置的平直边和一对相对设置的弧形边。
在本示例中,灯头20包括一对相对设置的硅胶圈204,该硅胶圈204为条状结构。条状结构的隔热件24呈弧形,且与隔热件24的弧形边相适配。两个硅胶圈204分别设置在隔热件24的两个弧形边上。
两个硅胶圈204连同隔热件24共同设置在壳体21的开口211处,两个硅胶圈204均与壳体21的内壁相抵接。壳体21的内壁与隔热件24两侧的平直边区域之间具有间隔。

在本实施例中,附件外壳41外包括装配柱43,装配柱43凸设在底座412的内壁上。隔热件24的外周边缘、菲涅尔镜片231的外周边缘以及扩散片232的外周边缘均设有与装配柱43卡接的装配口233。
硅胶圈204的外周轮廓与隔热件24的形状相适配,则硅胶圈204的外周侧壁内凹形成装配口233。装配口233与装配柱43卡接,以使隔热件24连同硅胶圈204、菲涅尔镜片231以及扩散片232固定在附件外壳41的装配区4123中。
当隔热件24连同硅胶圈204、菲涅尔镜片231以及扩散片232固定在附件外壳41的装配区4123中时,底座412的挡止部4122能够在隔热件24及硅胶圈204的一侧形成挡止,避免隔热件24和硅胶圈204由附件外壳41中脱出;顶盖413的盖体部4131能够在扩散片232的一侧形成挡止,避免扩散片232由附件外壳41的中脱出,以保证光效附件40整体结构的稳定性。
