具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请的技术方案提供的灯具进行详细地说明。
如图1至图9所示，本申请的实施例提供了一种灯具，包括：灯筒100、发光模组210、第一配光元件220、第二配光元件230、支架组件300和驱动机构400。
灯筒100具有出光侧，以便于光线照射至目标物体上。
发光模组210设置于灯筒100内，并且，发光模组210朝向出光侧。发光模组210发出的光线自灯筒100的出光侧射出。
在本实施例中，发光模组210包括：光源211、光源支架212、第三配光元件213和第三配光元件支架214。
光源支架212和第三配光元件支架214均固定于灯筒100，光源211设置于光源支架212，第三配光元件213设置于第三配光元件支架214，第三配光元件213朝向第二配光元件230。
光源211发出的光线依次穿过第三配光元件213、第二配光元件230和第一配光元件220，然后自灯筒100的出光侧射出灯具之外，并形成光斑。
其中，第三配光元件213可以为聚焦透镜或散焦透镜，这里不作具体限制。
在一些实施例中，发光模组210还包括：连接线215和固定卡扣216。
其中，连接线215的一端与灯具的电路板431电连接，连接线215的另 一端与光源211电连接，从而，为光源211传输电能。固定卡扣216用于固定连接线215，具体而言，固定卡扣216可拆卸地设置于灯筒100的内壁上。
第一配光元件220设置于灯筒100的出光侧与支架组件300之间。
第一配光元件220可以为具有调焦功能的透镜，如液体透镜、微透镜等，这里不作具体限制。
第二配光元件230固定于支架组件300，并且，第二配光元件230位于发光模组210与第一配光元件220之间。
第二配光元件230可以为具有调焦功能的透镜，如液体透镜、微透镜等，这里不作具体限制。
支架组件300可活动地设置于灯筒100内。
在一些实施例中，支架组件300相对于灯筒100在转动的同时发生移动。
驱动机构400设置于灯筒100内，驱动机构400与支架组件300相连，并且，驱动机构400驱动支架组件300活动，使得第二配光元件230在预设方向上相对于第一配光元件220运动，预设方向平行于灯筒100的轴线。
在本实施例中，由于发光模组210设置于灯筒100内，支架组件300可活动地设置于灯筒100内，第一配光元件220设置于灯筒100的出光侧与支架组件300之间，第二配光元件230固定于支架组件300，驱动机构400与支架组件300相连，驱动机构400通过支架组件300驱动第二配光元件230在预设方向上相对于第一配光元件220运动，以改变第二配光元件230与第一配光元件220之间的距离，因此，灯具的光束角范围可调，使得照射至目标物体上的光斑大小可调，从而，满足了用户不同的用灯需求。
需要说明的是，上述的光束角具体指光源211发出的光束自灯筒100的出光侧照射至灯具之外的光线角度，通常，光束角在被照射面上的直观体现为光斑和照度。
本实施例中，发光模组210发出的光线的光束角的范围为15°～65°。
一些其他实施例中，发光模组210发出的光线的光束角大于65°或小于 15°。具体而言，该光束角的范围可以根据实际使用需求进行设置，这里对此不作具体限制。
在一些实施例中，驱动机构400包括：驱动件410和转动件420。
转动件420形成有凸起部421，凸起部421具有朝向支架组件300的斜坡421a，斜坡421a沿转动件420的周向倾斜，也就是说，凸起部421为弧形结构，且凸起部421的高度沿转动件420的周向逐渐减小，即凸起部421的高度沿转动件420的旋转方向逐渐减小。
支架组件300抵接斜坡421a，即支架组件300与斜坡421a接触且向斜坡421a施加一定的作用力。
驱动件410与转动件420相连，驱动件410驱动转动件420相对于支架组件300绕灯筒100的轴线转动，以改变支架组件300与斜坡421a的抵接位置。
在驱动件410驱动转动件420转动的过程中，斜坡421a随着转动件420一起转动，此时斜坡421a与支架组件420的抵接位置发生改变；与此同时，凸起部421的高度沿转动件420的旋转方向逐渐变大或变小，斜坡421a驱动支架组件300在预设方向上相对于第一配光元件220移动。
在本实施例中，驱动件410通过转动件420驱动支架组件300逐渐靠近或远离第一配光元件220，有利于灵活控制支架组件300的移动精度，从而精确控制第二配光元件230与第一配光元件220之间的距离。
在一些实施例中，驱动件410为电机。在另一些实施例中，驱动件410为其他能够驱动转动件420转动的驱动结构。
在又一些实施例中，驱动件410为气缸、液压缸或形状记忆合金件等，此时，驱动件410直接与支架组件300连接，从而驱动支架组件300相对于第一配光元件220移动。
在一些实施例中，支架组件300朝向转动件420的一面设有抵接部，当凸起部421的高度沿转动件420的旋转方向逐渐减小时，该抵接部的高度沿 转动件420的旋转方向的反方向逐渐减小。在支架组件300朝向第一配光元件220移动的过程中，抵接部的最高处逐渐靠近凸起部421的最高处，抵接部与凸起部421的斜坡421a之间采用滑动摩擦方式。
在另一些实施例中，支架组件300包括：支架310和第一滚轮320。
支架310设有第一容纳槽311，第一容纳槽311的开口朝向转动件420。
其中，第一容纳槽311为弧形槽。由于凸起部421为沿转动件420的周向设置的弧形结构，因此，一些实施例中，第一容纳槽311与凸起部421相对设置，以便于第一滚轮320的灵活设置。此外，在一些实施例中，第一容纳槽311的数量为至少两个时，各第一容纳槽311相连通，从而形成环形凹槽。
第一滚轮320设置于第一容纳槽311，第一滚轮320部分凸出于第一容纳槽311，并可转动地抵接于斜坡421a，使第一滚轮320与斜坡421a滚动配合。
在本实施例中，第一滚轮320与斜坡421a之间采用滚动摩擦，二者之间的接触面积较小，有利于减小凸起部421的磨损，并且驱动件410只需输出较小的驱动力即可，有利于延长驱动件410的使用寿命。
在一些实施例中，凸起部421位于转动件420的边缘。此时转动件420转动较小的角度即可驱动支架组件300移动，有利于节省驱动件410的能耗；同时凸起部421位于转动件420的边缘，以便于凸起部421的设置。
凸起部421的数量为至少两个，各凸起部421沿转动件420的周向间隔设置，第一滚轮320和第一容纳槽311均与凸起部421一一对应设置，从而增大支架组件300与转动件420之间的接触面积，进而提高支架组件300的移动稳定性，避免支架组件300发生倾斜。
在一些实施例中，驱动机构400还包括：与灯筒100相固定的电路板组件430，以及与电路板组件430滚动配合的第二滚轮440。
转动件420设有第二容纳槽422。
其中，第二容纳槽422为弧形槽，以便于第二滚轮440的灵活设置。
另一些实施例中，第二容纳槽422为直线性结构。
在其它一些实施例中，第二容纳槽422的数量为至少两个，各第二容纳槽422沿转动件420的周向间隔设置，第二滚轮440与第二容纳槽422一一对应设置，从而增大电路板组件430与转动件420之间的接触面积，进而提高支架组件300的移动稳定性，避免支架组件300发生倾斜。
此外，一些实施例中，当第二容纳槽422的数量为至少两个时，各第二容纳槽422相连通，从而形成环形凹槽。
电路板组件430设置于转动件420的上方，并且，驱动件410的输出轴穿过电路板组件430上的避让孔与转动件420相连，第二容纳槽422的槽口朝向电路板组件430。
第二滚轮440可转动地设置于第二容纳槽422，且第二滚轮440部分凸出于第二容纳槽422，第二滚轮440与电路板组件430抵接。具体而言，第二滚轮440与电路板组件430之间采用滚动摩擦，二者之间的接触面积较小，因此，有利于减小电路板组件430的磨损，并且驱动件410只需输出较小的驱动力即可，从而延长驱动件410的使用寿命。或者，在另一些实施例中，电路板组件430与转动件420直接接触，此时二者之间采用滑动摩擦方式。
在一些实施例中，电路板组件430包括：固定于灯筒100的支撑板432和设置于支撑板432与驱动件410之间的电路板431。
第二滚轮440与支撑板432背向驱动件410的一侧滚动配合，并且，支撑板432朝向驱动件410的一侧具有若干支撑脚432a。
电路板431与驱动件410电连接，电路板431还与发光模组210电连接，并且，电路板431与驱动件410均固定在支撑脚432a上。
其中，电路板431用于为驱动件410和发光模组210供电。电路板431与支撑板432之间具有间隙。
一些实施例中，电路板431相背的两面均设置有电子器件，从而提高电 路板431的利用率。
本实施方案中，支撑板432不仅为电路板431和驱动件410提供设置基础，而且可以保护电路板431，避免第二滚轮440与电路板431直接接触。
在一些实施例中，电路板431和驱动件410均通过连接件540固定在支撑脚432a上。
其中，驱动件410的外周面具有连接部411，连接件540的一端穿过连接部411和电路板431上的通孔与支撑脚432a上的螺纹连接孔螺纹配合。连接件540可以为螺纹连接件，如螺栓、螺钉等，这里不作具体限制。
在另一些实施例中，支撑脚432a的数量为至少两个，各支撑脚432a沿驱动件410的输出轴的周向间隔设置，连接件540和设置于驱动件410的外周面上的连接部411均与支撑脚432a一一对应设置，从而提高驱动件410和电路板431的稳定性。
在一些实施例中，支架310包括：架体312和支撑件313。
架体312形成有连接部312a，第二配光元件230设置于架体312。
支撑件313与连接部312a的自由端可拆卸连接，第一容纳槽311设于支撑件313。
其中，支撑件313与连接部312a的自由端螺纹连接，例如通过螺栓连接等，这里不作具体限制。
灯具还包括：套设于连接部312a的弹性件510和限位件520。
限位件520固定于灯筒100。
其中，限位件520与灯筒100之间可以通过焊接、螺栓连接等方式连接，这里不作具体限制。
弹性件510的第一端与支撑件313抵接，弹性件510的第二端与限位件520限位配合，弹性件510用于驱动支撑件313抵接斜坡421a。
在本实施例中，弹性件510始终处于压缩状态，弹性件510的第一端对支撑件313施加作用力，以使设置在支撑件313上的第一滚轮320始终抵接 于斜坡421a，从而提高支架310的稳定性；并且，在凸起部421驱动支架组件300相对于第一配光元件220移动的过程中，弹性件510可以起到缓冲作用，故该方案有利于提高支架组件300的移动稳定性。另外，弹性件510和限位件520均套设于连接部312a，连接部312a可以为弹性件510提供导向作用，从而避免弹性件510发生倾斜。
在另一些实施例中，弹性件510的第二端抵接于限位件520朝向转动件420的一面；或者，限位件520设有导向凹槽，弹性件510的至少部分位于导向凹槽内，弹性件510的第二端与导向凹槽的槽底抵接。
其中，连接部312a和导向凹槽分别位于弹性件510之内和之外，二者同时为弹性件510提供导向，以进一步避免弹性件510发生倾斜，提高支架组件300的移动稳定性。
在一些实施例中，限位件520包括相连的环形限位板521和限位套筒522。
在一些实施例中，环形限位板521的边缘设有翻边，从而加强环形限位板521的强度。
环形限位板521设置于限位套筒522与支撑件313之间，环形限位板521设有导向通孔，导向通孔与限位套筒522相连通，弹性件510的第二端穿过导向通孔与限位套筒522的底壁限位配合。
其中，弹性件510的部分位于限位套筒522内，限位套筒522不仅具有导向作用，而且可以保护弹性件510。
另一些实施例中，限位件520只包括环形限位板521。
在其它一些实施例中，凸起部421的最大高度等于支撑件与环形限位板521之间的最大距离，此种情况下，在支架组件300朝向第一配光元件220移动的过程中，支撑件313可与环形限位板521接触，从而起到限位的作用，避免第二配光元件230与第一配光元件220之间的距离过小。
在一些实施例中，架体312还包括：与连接部312a相连的基座312b。
其中，基座312b与连接部312a可以为一体式结构，也可以为分体式结 构，这里不作具体限制。
连接部312a与基座312b相连的一端形成有加强筋312a1，加强筋312a1位于基座312b与限位件520之间。
其中，加强筋312a1用于提高架体312的强度。
具体的，加强筋312a1为三角结构，此时加强筋312a1分别与连接部312a和基座312b连接，以进一步提高基座312的强度。
在其它实施例中，在支架组件300远离第一配光元件220移动的过程中，加强筋312a1可与限位套筒522接触，从而起到限位的作用，避免第二配光元件230距离发光模组210过近。
在一些实施例中，支撑件313为环形结构，以轻量化所述支撑件313。
另一些实施例中，支撑件313为圆形板。
连接部312a为连接杆，连接杆的数量为至少两个，各连接杆沿支撑件313的周向间隔设置，各连接杆之间围成容纳空间，相邻的连接杆之间形成避让空间，发光模组210设置于容纳空间内，发光模组210通过避让空间与灯筒100相连。
在本实施例中，采用此种设置方式，不仅可以提高空间利用率，而且有利于减小架体312的重量，以便于驱动件410输出较小的驱动力即可驱动支架组件300移动，同时可以节省支架组件300的制作成本。
弹性件510与连接杆一一对应设置。在确保架体312的强度的基础上，采用多个弹性件510有利于提高支架组件300的移动稳定性。
在其它实施例中，连接部312a为筒状结构，在确保连接部312a的强度的基础上，采用筒状结构有利于减小连接部312a的重量。
在一些实施例中，转动件420包括环形部423和三爪连接部424，三爪连接部424与环形部423的内表面相连，凸起部421设置于环形部423。该方案采用此种结构的转动件420，在确保转动件420的强度的基础上，可以减小转动件420的重量，以便于驱动件410驱动转动件420转动。
驱动件410的输出轴连接于三爪连接部424的中心轴处。也就是说，驱动件410的输出轴与转动件420的旋转中心轴重合，以使转动件420在转动过程中更加稳定，避免转动件420发生倾斜。
另一些实施例中，三爪连接部424为两爪连接部或四爪连接部等，这里不作具体限制。
在一些实施例中，灯筒100包括筒体120、上筒盖130和下筒盖140。
上筒盖130和下筒盖140分别与筒体120的两端螺纹连接，以便于发光模组210、第一配光元件220、第二配光元件230、支架组件300和驱动件410等结构设置于灯筒100的容纳空间内。
驱动机构400的至少部分位于上筒盖130内，上筒盖130的外表面设有多个散热翅片131。
其中，驱动机构400距离散热翅片131较近，而散热翅片131有利于增大上筒盖130的散热面积，在驱动机构400工作的过程中，驱动机构400产生的热量通过散热翅片131尽快地散发出去，以保护驱动机构400。
下筒盖140设有透光部110，透光部110朝向出光侧，发光模组210朝向透光部110。
其中，透光部110为通光孔，或者为透明结构，从而起到防尘的效果。
在其它实施例中，灯具还包括第一配光元件支架530。第一配光元件支架530可拆卸地设置于筒体120的内壁上，第一配光元件220设置于第一配光元件支架530，以便于第一配光元件220的设置。
在一些实施例中，灯具还包括感应装置，感应装置包括感应件550和线缆560。
感应件550设置于第一配光元件支架530，线缆560的一端与感应件550电连接，线缆560的另一端与电路板431电连接。该实施例通过设置感应装置以便于用户通过感应的方式控制灯具的开关、工作模式的切换等。感应件550可以为激光感应件，当然也可以为其他类型的感应件，这里不作具体限 制。
在其它实施例中，灯具还包括导线570。导线570的一端与电路板431电连接，导线570的另一端穿过灯筒100的上筒盖130的中心孔与电源电连接，从而为灯具供电。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
