本申请提供的优选实施例的射灯，如图1所示包括主体部2和调节安装部1。
其中主体部2包括具有容置空间2078的灯体207，在本实施例中光源 204、光源支架205、透镜203设置在灯体207的容置空间2078中，光源204设置于光源支架205，而光源支架205通过螺钉206固定在灯体207的底部。灯体207的一端设置有下端盖202，透镜203一端和灯体207底部抵接，另一端和下端盖202抵接。安装时将光源支架205、光源204、透镜203依次装入灯体207后，并以下端盖202覆盖端口，主体部2的组装完成。在本实施例中灯体207同时充当射灯的外壳和散热器，因此在灯体207的外表面还设置有散热鳍片，在其他实施例中灯体外部也可以是平滑表面，或设置另外的散热器。本实施中光源204为COB光源，其安装在光源支架205上，在其他实施例中也可以是设置有LED的光源板，光源板可通过螺钉直接固定在灯体207的底部，本申请对此不作限定。
我们通过图2和图3来详细说明一下本实施例中下端盖202和灯体207之间的连接方式。如图3所示，灯体207形成具有开口2071的容置空间2078，下端盖202覆盖开口2071。灯体207的开口2071处的内侧壁上设置有凸块2072，如图下端盖202呈圆环形,其外侧壁设置有凸出于外侧壁并沿周向延伸的扣持部2022。扣持部2022一端前方为凸块入口2021，扣持部2022靠近凸块入口2021一侧具有导向斜面，另一端设置有同样凸出于外侧壁并沿轴向延伸的限位部2023。当下端盖202和灯体207连接时，下端盖202伸入灯体207的开口2071，凸块2072在凸块入口2021处径向运动，此时凸块2072和扣持部2022径向不重叠。而后，旋转下端盖202，凸块2072沿周向在扣持部2022上方移动，直至被限位部2023限位无法继续向前，此次凸块2072和扣持部2022径向重叠，下端盖202无法脱离灯体207，两者连接完成。为了使得连接可靠，一般我们需要设置两个以上的凸块2072和扣持部2022，两者成对设置，且所述凸块和所述扣持部成对设置,沿圆周均匀排布。
在上述结构中虽然限位部2023限制了凸块2072继续向前，但是无法限制其回退，因此本实施例的下端盖202上还设有弹性臂2024，弹性臂2024沿圆周方向延伸，形成和下端盖202同轴的圆弧段，其一端和下端盖202连接，另一端为自由端，自由端和下端盖202之间留有间隙。自由端上设置有沿径向向外凸出的凸点2025。灯体207设置有可收容凸点2025的开槽2074。当下端盖202和灯体207连接固定后，凸点2025位于开槽2074内。灯体207上还设置有定位标记2073，当凸点2025对准定位标记2073时，凸块2072位于扣持部2022的凸块入口2021位置，而当凸点2025旋转到开槽2074位置时，凸块2072位于扣持部2022上方和扣持部2022径向重叠。安装时只需将弹性臂2024上的凸点2025对准灯体207上的定位标记2073，右旋下端盖202将凸点2025卡在灯体207的开槽2074位置，此时下端盖无法继续旋转。拆卸时候，只需将弹性臂2024上的凸点2025往里按，左旋下端盖202即完成下端盖202的拆卸。此结构方便快捷，可以实现对透镜的快速更换。
如图4所示，调节安装部1包括反射器101、面环102、旋转连接件105、上端盖106。面环102主要的作用是对灯具进行安装固定，在本实施例中，面环102上设置有弹片103，面环102通过弹片103安装在安装面的开孔中，在其他实施例中，面环上也可以配置弹簧、支架等其他安装结构。射灯的出光一般是有方向性，由于需照射位置的不同，需要对灯具本身或配光器件进行调节，面环102安装在天花板之后无法动作，因此通常会在面环102和灯具之间设置连接件，使得光源或配光器件可以相对于面环102进行旋转、移动等动作。在本实施例中设置有旋转安装件105，其与面环102卡扣连接，可相对于面环102同轴旋转。在其他实施例中，旋转连接件105和面环102也可以通过螺钉连接两者侧壁，以螺钉为转轴，转轴方向平行于安装面。在 本实施例中反射器101作为射灯的二级配光器件是一个偏光反射器，其和旋转连接件105卡扣连接，跟随旋转连接件105一起转动时，可改变射灯的照射方向。
本实施例中反射器101、面环102、旋转连接件105具体的连接方式如图4、图5所示。旋转连接件105上设置有卡爪1051，面环102的内侧壁上设置有第一卡持部1021，卡爪1051和卡持部1021卡接后可以沿圆周方向转动。旋转连接件105上还设置有卡钩1052，反射器101上设置有与之配合的第二卡持部1011，安装时卡钩1052和第二卡持部1011卡接。
通过上述介绍，我们可以发现本实施例的射灯被分成了包括光源的主体部2和作为安装和调节出光方向的调节安装部1这个主要部分，这两者之间是分离的，而作为一个灯具整体需要将他们连接起来。为了使主体部2可以灵活组配不同类型的安装面环或二级配光器件，在本实施例中主体部2和调节安装部1之间采用磁性连接，因此可以方便的分离和组合这两个部分。具体地，主体部2包括第一磁性连接部201，调节安装部1包括第二磁性连接部107，主体部2和调节安装部1通过第一磁性连接部201、第二磁性连接部107相互吸合实现连接。在主体部2第一磁性连接部201设置在下端盖202上，在调节安装部1需要一个相对应的部件，因此调节安装部1还包括上端盖106，第二磁性连接部107设置其上。连接时上端盖106下端盖202对准吸合即可。在本实施例中上端盖106通过螺钉104安装在旋转连接件105上，在需要调节照射角度时，主体部2随着旋转连接件105一起转动。在其他较佳实施例中，上端盖106也可以设置在面环102上，这样当调节照射角度时仅旋转连接件105和反射器101转动，而光源部分不动。
第一磁性连接部201包括多个第一磁体、第二磁性连接部107包括多个 第二磁体，第一磁体和第二磁体成对设置，在本实施例中第一磁体、第二磁体为永磁体，且两者相对侧的磁性相反。在其他较佳实施例中第一磁体、第二磁体还可以一者为永磁体，另一者为可被永磁体吸附的磁性材料，如铁等金属材料。第一磁体和第二磁体的数量优选的为两个以上，在本实施例中为三个。三对磁体分别设置在不同位置，以加强稳定性。本实施例中上端盖106、下端盖201均为圆环，因此三对磁体沿圆周均匀排布。上端盖106设置有磁体容置槽1061，下端盖202设置有磁体容置槽2028，第一磁体、第二磁体通过点胶分别设置于在设置有磁体容置槽2028、1061中。在其他较佳实施例中第一磁体、第二磁体还可以通过干涉塞入磁体容置槽2028、1061实现固定。上文对本申请优选实施例的描述是为了说明和描述，并非想要把本申请穷尽或局限于所公开的具体形式，显然，可能做出许多修改和变化，这些修改和变化可能对于本领域技术人员来说是显然的，应当包括在由所附权利要求书定义的本申请的范围之内。
