请参照图1、图4所示，本申请的优选实施例提供一种调焦射灯100，其包括灯体1、光源组件2、调焦件3、光学组件4、限位件5、驱动电源6以及转动连接件7。
结合图6、图7所示，灯体1的形状为圆筒状，灯体1为铝材一体成型制造而成，其具有沿轴向延伸的中心线13。灯体1的前端部设置有安装口11、内部设置有可安装光源组件2的光源腔12。灯体1在光源腔12内设置有基座15，光源组件2包括设置在基座15上的光源板21、若干个设置在光源板21上且与光源板21电性连接的发光元件22。光源板21可以是PCB板，其可以通过螺钉等固定在基座15上，发光元件22可以是固态发光元器件， 例如LED灯珠、COB光源或SMD光源等。某些实施例中，光源板21也可是铝基板，其还可以通过胶粘、焊接、铆接或卡扣等方式安装在基座15上，发光元件22的个数可以是单颗，也可是两颗、三颗或更多颗，多颗发光元件22可以沿周向布置在光源板21上，具体不作限制。
结合图4、图6所示，调焦件3的形状为圆筒状，调焦件3为铝材一体成型制造而成。调焦件3后端部设置有入光口31、内部设置有光学腔32、前端部设置有出光口33，光学组件4设置在光学腔32内。光源组件2发出的光线经入光口31射入光学腔32，经光学组件4配光后从出光口33射出。
结合图4、图7所示，调焦件3与灯体1为螺纹连接。具体的，结合图4、图7所示，调焦件3的外周壁上设置有外螺纹34，灯体1的内周壁上设置有沿轴向延伸且与外螺纹34相配合的内螺纹14。外螺纹34为形成在调焦件3外周壁上且沿轴向螺旋延伸的凸棱，内螺纹14为形成在灯体1内周壁上且沿轴向螺旋延伸的凹槽。为了简化调焦件3与灯体1之间的螺纹连接结构，调焦件3后端部设置有向外凸伸的凸缘35，外螺纹34仅设置在凸缘35上。调焦件3在凸缘35处与灯体1构成螺纹连接。某些实施例中，调焦件3也可不设置凸缘35，可以在调焦件3外周壁上布满外螺纹；也可将调焦件3的内径设计较灯体1的直径更大，使得调焦件3包覆在灯体1的外周壁上并在包覆处螺纹连接，即在调焦件3内周壁的前端设计内螺纹，在灯体1的外周壁设计外螺纹，具体不作限制。上述设计，不论调焦件3是收容在灯体1内并与灯体1螺纹连接，抑或是包覆在灯体1外周壁上并与灯体1螺纹连接，调焦件3始终有部分是与灯体1相重叠的，并且调焦件3与灯体1在二者的重叠处螺纹连接，均能够实现调焦件3与灯体1直接螺纹连接，使得调焦件3可相对灯体1转动并产生沿轴向的位移，以便光学组件4远离或靠近光源组件2，实现调焦目的，结构更简单，成本更低。
结合图2、图3所示，调焦件3相对灯体1具有最小位移和最大位移，在最小位移处，调焦件3前端部有部分裸露在灯体1的安装口11的外侧且形成供用户操作的操作部分。在一些优选的实施例中，调焦件3相对灯体1移动至最小位移处，操作部分的长度为5㎜～8㎜，在最大位移处，调焦件3伸出灯体1部分的长度为30㎜～40㎜。这使得调焦射灯的光束角可以在15°～50°范围内变焦，可适用于不同场景应用，灵活多变。
结合图6、图7所示，灯体1在安装口11处设置有用于阻止调焦件3从灯体1上脱落的限位件5。限位件5的形状为环形，其与灯体1的安装口11的形状相匹配。限位件5卡扣连接在灯体1上。具体的，灯体1的内周壁靠近安装口11处设置有第一卡合部17，限位件5的外周边缘设置有若干个与第一卡合部17相卡扣配合的第一卡合配合部51。其中第一卡合部17为开设在灯体1内周壁前端上的卡槽，第一卡合配合部51为构造在限位件5外周边缘上且向外凸伸的卡钩。某些实施例中，限位件5不限于采用卡扣方式安装至灯体1内，也可是其他连接结构。例如螺纹连接，可以在限位件5的外周壁设计外螺纹，在灯体1的内周壁设计内螺纹；或者采用胶粘连接或螺钉连接等，具体不作限制。操作时，调焦件3转动 并相对灯体1产生沿轴向的位移，移动至最大位移处时，由于其后端部的凸缘35的直径要大于限位件5的直径，因此限位件5将调焦件3限位在该最大位移处并阻止调焦件3脱出灯体1。
结合图4、图7所示，光学组件4包括第一透镜41和第二透镜42。调焦件3的内周壁上设置有第二卡合部36，第一透镜41的外周边缘设置有若干个与第二卡合部36相卡扣配合的第二卡合配合部413。其中，第二卡合部36为形成在调焦件3内周壁上的卡槽，第二卡合配合部413为构造在第一透镜41外周边缘上的卡钩。调焦件3的内周壁在位于第一透镜41的下侧还设置有一段台阶槽，其用于支撑和收容第二透镜42，安装时，可将第二透镜42安置在该台阶槽内，第一透镜41卡扣在调焦件3内周壁的卡槽内，第二透镜42与第一透镜41相抵接。某些实施例中，该台阶槽的形状可构造为第二透镜42的形状相匹配。此外，第一透镜41安装至调焦件3内的安装结构不限于上述的卡扣结构，第二透镜42也不限于收容在台阶槽内，光学组件4与调焦件3之间的安装结构也可是其他连接结构，例如在调焦件3的内周壁设计内螺纹，在第一透镜41与/或第二透镜42的外周壁上设计外螺纹，第一透镜41与/或第二透镜42通过螺纹连接的方式安装至调焦件3内。还可在调焦件3的周侧壁打孔，通过螺钉方式固定第一透镜41与/或第二透镜42。还可是间隙配合或过盈配合方式，具体不作限制。需要说明的是，第一透镜41和第二透镜42的类型可以是聚光型透镜，也可是扩散型透镜，也可其中一个是聚光型透镜，另一个是扩散型透镜，在此不限制第一、二透镜的具体类型，可以根据调焦射灯的具体应用场景选择合适类型的透镜即可。
结合图10、图11所示，第一透镜41具有第一入光面411和第一出光面412，第一出光面412上设置有若干个混光区域4121，若干个混光区域4121自第一透镜41的中心沿径向向外间隔布置，各个混光区域4121均沿周向延伸，其形状类似一圈圈环绕布置的环带。在第一出光面412上，自第一透镜41的中心沿径向延伸至其外周边缘的径向路径为非均匀有理B样条曲线(或称NURBUS曲线)，由该曲线绕着透镜的轴线旋转一周形成的曲面为非均匀有理B样条曲面(或称NURBUS曲面)，采用该曲面设计的第一出光面412，其形成的多个混光区域4121能够使得光线射出第一透镜41后在各个混光区域4121外发生多次交叉混光，混色效果更好，光线柔和不刺眼。为了增强第一透镜41的混光效果，第一入光面411上还设置有用于混光的珠面。某些实施例中，第一入光面411上不限于设计珠面来混光，还可设计磨砂面或鳞甲面，具体不作限制。
结合图12、图13所示，第二透镜42包括第二入光面421和第二出光面422，第二入光面421上设置有用于混光的珠面，其中第二入光面421上的珠面相较于第一入光面411上的珠面，更加致密，构成珠面的每个单元面的尺寸也更小，可以调整经第一透镜41出射的光线形成的光斑，使得光斑亮度更加均匀。某些实施例中，第二入光面421上不限于设计珠面来混光和调整光斑亮度均匀性，还可设计磨砂面或鳞甲面，具体不作限制。
结合图14所示，发光元件22发出的光线经第一透镜41射出后，光线能够在第一透镜 41的多个混光区域4121外发生多次交叉混光，经第二透镜42射出，出光更加柔和，光斑亮度更加均匀。
再结合图2、图3所示，为了方便灯体1的多角度调节，使得调焦射灯100在安装后适于照射范围更大以及照射角度更加灵活多变，驱动电源6与灯体1之间设置有转动连接件7。
结合图5、图6以及图8、图9所示，驱动电源6包括壳体61、设置在壳体61内的主控元件62，主控元件62通过导线63与光源板21电性连接。
转动连接件7一端部通过第一转轴71与壳体61转动连接、另一端部通过第二转轴72与灯体1转动连接，第一转轴71具有沿其长度方向延伸的第一轴心线711，第二转轴72具有沿其长度方向延伸且与第一轴心线711相垂直的第二轴心线721。
壳体61上设置有转动孔611，第一转轴71转动配合在转动孔611内，第一转轴71上设置有与转动孔611的孔壁摩擦接触的第一阻尼件81。灯体1后端部设置有转动座16，转动座16上设置有与第二转轴72转动配合的转动腔161，转动座16上设置有与第二转轴72摩擦接触的第二阻尼件82。灯体1后端部设置有容置腔162，转动座16收容在容置腔162内，灯体1后端部设置有用于封闭容置腔162的后盖163，灯体1侧壁上开设有用于避让转动连接件7的缺口164。
第一阻尼件81的设置，使得第一转轴71在转动过程中能够随时在任意角度位置止转停留，第一转轴71的转动角度范围在0°～360°，方便灯体1绕着第一轴心线711调节角度。第二阻尼件82的设置，使得第二转轴72在转动过程中能够随时在任意角度位置止转停留，第二转轴72的转动角度范围在0°～90°，方便灯体1绕着第二轴心线721调节角度。
结合图4所示，其中第一阻尼件81为固定安装在第一转轴71轴端上的摩擦垫片。第二阻尼件82为与转动座16固定连接且将第二转轴72夹紧在两者之间的压片。某些实施例中，第一阻尼件81以及第二阻尼件82也可是采用橡胶圈或硅胶垫等，具体不作限制。除此之外，在一些优选实施例中，第一转轴71与驱动电源6的壳体61之间的转动连接结构以及第二转轴72与灯体1之间的转动连接结构不限于轴孔配合，也可是其他连接结构，例如枢接、铰接等，具体不作限制。
另外，需要说明的是，驱动电源6可以与现有的轨道射灯的安装轨道配合使用，例如磁吸轨道或吊装轨道，使得调焦射灯作为轨道射灯使用；驱动电源6也可固定安装在室内天花板吊顶上，使得调焦射灯作为普通的低压射灯使用；也可利用吊线装置取代转动连接件7，使得调焦射灯作为吊线射灯使用，具体不限制射灯的应用类型。
本申请的技术范围不仅仅局限于上述说明书中的内容，本领域技术人员可以在不脱离本申请技术思想的前提下，对上述实施例进行多种变形和修改，而这些变形和修改均应当属于本申请的保护范围内。
