本实用新型的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本实用新型的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
下面参照说明书附图，描述本实用新型实施例的灯具100。
参照图1至图3根据本实用新型的第一方面实施例的灯具100，包括壳体、光源120和固定件130，壳体设置有容置腔260和出光口250，出光口250用于出射光线。光源120安装于容置腔260内。固定件130固定于壳体的外表面，固定件130远离壳体的一侧设置有多个抵持凸台150，抵持凸台150具有弹性，各抵持凸台150沿壳体的高度方向间隔设置。本实施例的灯具100能够适配厚度不同的天花300。
具体的，光源120可以通过电连接线与外界电源电连接，通过外界电源为光源120持续供电；也可以为光源120设置有内置电池，通过内置电池为光源120供电，灯具100安装于天花300后即可直接使用。灯具100还可以设置有无线组件或声控开关，通过无线组件或声控开关来控制灯具100的打开与关闭。固定件130的材料可以选择为硅胶或塑料等弹性材料。壳体可以选择为由上壳体110和下壳体200固定连接所组成的壳体，也可以是一体成型的整装壳体。
固定件130可以通过粘接或者螺栓等预紧件预紧的方式固定在壳体上。抵持凸台150的形状，可以根据壳体的外表面的形状和天花300的安装孔310的形状而改变，例如，将抵持凸台150设置为环形凸台，以与圆形或弧形的壳体外表面适配。
当灯具100沿天花300的安装孔310插入天花300时，抵持凸台150与安装孔310的孔 壁抵持变型。灯具100沿安装孔310插入一定深度后，部分抵持凸台150失去与安装孔310的孔壁的抵持，在弹力作用下恢复原来的形状，恢复形状后的抵持凸台150与天花300的上表面抵持，限制灯具100脱离安装孔310的运动。其余位于安装孔310内的抵持凸台150与安装孔310的孔壁抵持，由于抵持凸台150具有弹性，因此会存在沿安装孔310径向的形变力将灯具100进一步预紧在安装孔310内，进一步限制灯具100脱离安装孔310的运动，完成灯具100的固定安装。
通过设置多个抵持凸台150，使灯具100在应对不同深度的安装孔310时，均能存在至少一个抵持凸台150与天花300的上表面抵持，并通过位于安装孔310内的抵持凸台150对安装孔310的孔壁的抵持力，保证灯具100与天花300的连接强度，从而适配不同厚度的天花300。并且，在安装和拆卸灯具100时，工作人员只需抓持灯具100的壳体，克服抵持凸台150的形变力即可将灯具100从天花300上拆卸，降低了灯具100安装和拆卸于天花300上的难度，工作人员单手即可实现灯具100的安装和拆卸。
参照图1，根据本实用新型的一些实施例，固定件130设置有多个，各固定件130围绕壳体设置。通过将固定件130设置为多个，可以进一步提高灯具100与天花300的连接强度，或者，减少固定件130的耗材。
具体的，当灯具100的重量不同时，对连接于天花300时的连接强度也是不同的，通过将固定件130设置为多个，可以通过固定件130的数量控制灯具100与天花300的连接强度。当灯具100的重量较小时，设置有两个固定件130相对设置在壳体上，即可将灯具100稳定安装于天花300上。当灯具100的重量较大时，可以设置有三个、四个或者数量更多的固定件130在壳体上，以确保有足够的连接强度进行稳定安装。相对比仅设置有一个固定件130于灯具100的一侧，连接强度有所提升；相比于仅设置有一个固定件130围绕壳体的外表面，减少了连接强度的溢出和固定件130的耗材。
参照图3，根据本实用新型的一些实施例，抵持凸台150沿远离壳体的方向延伸，且抵持凸台150朝出光口250延伸。抵持凸台150的倾斜设置能够降低灯具100的安装难度并提高了灯具100与天花300的连接强度。
具体的，抵持凸台150的上下表面均呈现为自上向下倾斜的斜面。当灯具100插入固定孔时，由于抵持凸台150的上表面为斜面，抵持凸台150仅需发生较小的形变，即仅需克服较小的形变力，即可将灯具100插入固定孔内，降低了灯具100的安装难度。当灯具100插入至预计深度后，由于抵持凸台150的下表面也为斜面，灯具100要脱离安装孔310，需要克服较大的抵持凸台150型变量，即需要克服较大的抵持凸台150形变力，提高了灯具100 与天花300的连接强度。
根据本实用新型的一些实施例，抵持凸台150的延伸方向与固定件130的表面的夹角为45°～75°。将抵持凸台150的延伸方向与固定件130的表面的夹角大小控制在45°至75°之间时，灯具100较为容易插入安装孔310进行安装，且安装完毕后连接强度较高。
具体的，抵持凸台150的延伸方向与固定件130的表面的夹角大小可以选择为45°、60°或者75°。抵持凸台150的延伸方向与固定件130的表面的夹角大小会影响灯具100插入安装孔310和移出安装孔310所需克服的形变力。当抵抵持凸台150的延伸方向与固定件130的表面的夹角大小大于75°时，抵持凸台150的倾斜角度较小，对灯具100插入安装孔310和移出安装孔310所需克服的形变力影响不大。当抵持凸台150的延伸方向与固定件130的表面的夹角大小小于45°时，虽然灯具100插入安装孔310所需克服的形变力较原先有大幅度减小，但是抵持凸台150在水平方向上对天花300上表面的覆盖面积会变小，或者，需要使用更多的材料延长抵持凸台150，以保证抵持凸台150在水平方向上与天花300上表面有有足够的覆盖面积，以保证灯具100安装的稳定性，抵持凸台150的延长增加了制造成本。因此，将抵持凸台150的延伸方向与固定件130的表面的夹角大小控制在45°至75°之间时，灯具100较为容易插入安装孔310进行安装，且安装完毕后连接强度较高。
根据本实用新型的一些实施例，抵持凸台150的硬度设置在邵氏硬度A30至70度之间。将抵持凸台150的硬度设置在邵氏硬度A30至70度之间时，灯具100较为容易插入安装孔310进行安装，且安装完毕后连接强度较高。
具体的，抵持凸台150的硬度可以选择为30度、40度、50度、60度或70度，硬度的单位为邵氏硬度A。抵持凸台150的弹性与抵持凸台150的硬度有关，当抵持凸台150的硬度小于30度时，抵持凸台150的弹性较大，灯具100容易插入安装孔310内，但是此时抵持凸台150对天花300的抵持力较小，灯具100容易脱离安装孔310；当抵持凸台150的硬度大于70时，抵持凸台150的抵持力较大，但是抵持凸台150的弹性较弱且脆性增加，难以插入安装孔310内且容易损坏抵持凸台150的结构。因此，将抵持凸台150的硬度设置在30至70度之间，灯具100较为容易插入安装孔310进行安装，且安装完毕后连接强度较高。
参照图1和图2，根据本实用新型的一些实施例，还包括支架160，支架160与壳体可拆卸连接，固定件130固定于支架160远离壳体的一端。支架160的设置，有利于灯具100的模块化。
具体的，当固定件130的材料为硅胶等软质材料时，固定件130与壳体通过螺栓等预紧件固定连接时，需要使用多个预紧件将固定件130和壳体锁附，才能确保固定件130与壳体 的贴合，固定操作繁琐且不美观。而使用胶水对固定件130与壳体进行粘接，当固定件130损坏需要更换时，需要去除贴附在壳体上的胶层才能二次粘接，不方便工作人员进行维修。
支架160的材质可以选择为硬质塑料或者金属，当使用预紧件与壳体进行可拆卸固定时，最少设置两个孔位进行预紧即可把支架160固定在壳体上，减少了孔位的设置和预紧件的使用，并且支架160朝向壳体的一端的形状与壳体的外表面的形状相同，因此支架160与壳体的贴合度也较高。
由于固定件130固定在支架160上，当需要对固定件130进行更换时，将支架160和固定件130整体进行拆卸更换即可，方便快捷，实现了灯具100的模组化，拆卸下的支架160也可以在拆卸损坏的固定件130，重新固定新的固定件130，对支架160进行循环利用。
参照图1，根据本实用新型的一些实施例，支架160还设置有多个通孔190，固定件130还设置有多个卡接凸台140，各卡接凸台140一一插设于各通孔190。通过通孔190和卡接凸台140的配合，实现了支架160与固定件130之间的卡接固定，装配简单快捷，将卡接凸台140与通孔190对准后挤压支架160与固定件130即可。
根据本实用新型的一些实施例，固定件130与支架160粘接固定。
具体的，固定件130与支架160之间贴合面较大，通过粘接固定的方式，在保证固定件130与支架160之间的连接强度的同时，能够使得固定件130与支架160之间更加贴合。当需要进一步提高固定件130与支架160之间的连接强度时，可以将通孔190与卡接凸台140装配的方式与粘接的方式结合，通过包胶的形式，将卡接凸台140进一步固定在支架160上，进一步提高灯具100的结构稳定性。
参照图2，根据本实用新型的一些实施例，支架160设置有卡扣170，壳体上设置有滑槽230和卡槽220，支架160可沿滑槽230运动，滑槽230用于限制支架160远离壳体的运动，卡扣170卡接于卡槽220，卡扣170用于限制支架160脱离滑槽230的运动。
具体的，滑动部180可沿滑槽230上下滑动，并且，滑槽230的槽壁限制滑动部180沿除上下方向之外的其他方向的的运动。当支架160向下滑动至卡扣170与卡槽220对准后，卡扣170的一部分滑入卡槽220内，此时，卡扣170的上表面与卡槽220的内表面抵持，限制支架160向上的运动，支架160被固定在壳体上，相比于锁附预紧件的固定方式，装配效率更高，操作更简单，且不会存在粘接固定所留下的胶层。
参照图2，根据本实用新型的进一步实施例，壳体还设置有引导部210，沿支架160滑离滑槽230的方向，引导部210与卡槽220并列或并排设置，引导部210用于引导卡扣170滑入卡槽220。引导部210的设置能够降低支架160与壳体的装配难度。
为了实现卡扣170与卡槽220的卡接，卡扣170需要设置有朝向卡槽220的突出，以与卡槽220的槽壁进行抵持限位。在支架160沿滑槽230滑入的过程中，卡扣170会率先与壳体抵持变型，直至卡扣170滑动至卡槽220的位置后，才会失去抵持恢复原型，支架160在下滑的过程中，需要克服卡扣170的形变抵持所带来的摩擦力和形变力，装配难度较大。
具体的，引导部210为设置于壳体上的凹槽，凹槽内设置有引导斜面，当支架160沿滑槽230滑入到一定深度后，卡扣170滑入凹槽内并与斜面抵持，凹槽两侧的槽壁限制卡扣170的滑动方向，将卡扣170导引向卡槽220内，减少卡扣170由于装配误差而未能卡入卡槽220的几率。由于引导斜面为自靠近容置腔260的一侧向下倾斜至壳体外表面的斜面，卡扣170在于引导斜面抵持时，不会直接变型至与壳体外表面抵持时的最大形变量，而是逐渐发生形变，直到卡扣170脱离引导斜面与壳体外表面抵持时，才会达到最大形变量，此时，卡扣170仅需再运动较小的位移，即可滑入卡槽220内恢复形状，相比于卡扣170直接与壳体的外表面抵持的方式，可以减少装配支架160与壳体时的难度，且卡扣170在最大形变下维持的时间短，减小卡扣170因过度形变而弹性失效或脆性折断的可能性，延长支架160的使用寿命。
参照图1，根据本实用新型的一些实施例，壳体包括上壳体110和下壳体200，上壳体110与下壳体200可拆卸连接。
具体的，上壳体110和下壳体200可以选择使用螺栓等紧固件进行预紧的方式实现可拆卸连接，也可以通过卡接的方式实现可拆卸连接。通过将壳体分为上壳体110和下壳体200两部分，使得光源120和电源组件出现故障时，操作人员可以将壳体拆卸开对灯具100进行检修排查，延长灯具100的使用寿命。
参照图3，根据本实用新型的一些实施例，壳体还设置有限位部240，限位部240设置于壳体靠近出光口250的一端，限位部240用与于天花300抵持限位。
具体的，限位部240的位置大致与出光口250的位置齐平，当灯具100沿天花300的安装孔310插入至天花300的下表面快要与出光口250的位置齐平时，限位部240与天花300的下表面抵持，限制灯具100继续沿安装孔310进入天花300的运动，避免灯具100整个滑入天花300内或者出光口250的位置位于安装孔310内，导致灯具100未能安装在正确的位置上，导致灯光效果和美观度降低，工作人员也难以从天花300上取出灯具100。
上面结合附图对本实用新型实施例作了详细说明，但是本实用新型不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本实用新型宗旨的前提下作出各种变化。此外，在不冲突的情况下，本实用新型的实施例及实施例中的特征可以相互组合。
