为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅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做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。
以下结合附图，详细说明本申请各个实施例公开的技术方案。
如图1-图9所示，本申请实施例公开一种照明灯具，该照明灯具可以是路灯，其包括壳体100、光源组件200、透镜罩300、防变形组件400和驱动器500。壳体100与透镜罩300相连接并形成安装空间，具体的，壳体100和透镜罩300可以通过螺纹紧固件700连接，以便于该照明灯具的拆装和维护。光源组件200安装于该安装空间内，该光源组件200具体包括光源板210和设置于光源板210上的发光单元(图中未示出)，光源板210上开设连接通孔211。透镜罩300包括罩体310和设置于罩体310上的透镜320，透镜320可以罩设发光单元，发光单元发出的光线经过该透镜320后射出。防变形组件400的一部分位于连接通孔211内，且防变形组件400与透镜320连接，以向透镜320施加使其与光源板210相贴合的作用力。驱动器500可以安装于前述的安装空间内，其与光源板210电连接，进而驱动发光单元发光。
采用上述结构后，当光源板210或者透镜320受热出现变形趋势时，由于防变形组件400的作用，使得透镜320和光源板210之间的位置不容易发生变化，因而可以限制光源板210和透镜320的变形，以使发光单元、透镜320等部件之间的相对位置关系更加稳定，继而改善照明灯具的发光效果。
如图2-图4所示，一种实施例中，防变形组件400包括连接筋410和弹性卡件420，连接筋410的一端与透镜320连接，另一端穿过连接通孔211，并 与弹性卡件420卡接。为了改善防变形组件400与透镜320的连接强度，连接筋410可以与透镜320一体成型。连接筋410与弹性卡件420卡接后，弹性卡件420与光源板210抵靠，进而使得弹性卡件420相对于光源板210的位置被限制，继而限制连接筋410的位置，最终向透镜320施加使其与光源板210相贴合的作用力。此种实施例下，连接筋410与弹性卡件420之间的连接比较可靠，因此透镜320可以更可靠地与光源板210相贴合。
具体地，壳体100可以开设容纳槽110，弹性卡件420位于该容纳槽110内，使得照明灯具的结构更加紧凑。同时，连接筋410与弹性卡件420配合的过程中，容纳槽110可以辅助限制弹性卡件420的位置，使得连接筋410与弹性卡件420更可靠地配合。
可选地，上述弹性卡件420包括条形主体部421、设置于条形主体部421两端的第一卡接部422和第二卡接部423，第一卡接部422与第二卡接部423相对设置，且两者之间形成卡接间隙，连接筋410卡入该卡接间隙内，条形主体部421与第一卡接部422的连接处，以及条形主体部421与第二卡接部423的连接处均与光源板210相抵靠。条形主体部421具有一定的弹性，因此连接筋410卡入卡接间隙的过程中，第一卡接部422和第二卡接部423可以适当变形，使得连接筋410可以轻松地卡入卡接间隙内。并且，连接筋410卡接到位后，第一卡接部422和第二卡接部423复位，进而更可靠地防止连接筋410自卡接间隙脱出。另外，弹性卡件420与光源板210的抵靠部位分布于连接筋410的相对两侧，使得弹性卡件420相对于光源板210的位置稳定性更高，进而更好地克服因部件发热等原因产生的作用力，最终保证照明灯具的发光效果。
为了更便于操作人员将连接筋410与弹性卡件420连接到一起，连接筋410包括连接部411和卡持部412，卡持部412通过连接部411与透镜320连接，卡持部412具有相对于连接部411凸出的卡持面412a，以及与卡持面412a连接的V形导向面412b，卡持面412a与第一卡接部422和第二卡接部423相抵靠，V形导向面412b位于卡持面412a远离光源板210的一侧。连接筋410卡 入卡接间隙的过程中，V形导向面412b与第一卡接部422和第二卡接部423滑动配合，由于V形导向面412b与第一卡接部422和第二卡接部423配合的部分尺寸比较小，使得第一卡接部422和第二卡接部423更容易被打开。并且，卡持面412a与第一卡接部422和第二卡接部423之间的结合力较大，使得卡接的可靠性有所提升。
第一卡接部422的边沿和第二卡接部423的边沿的结构可以灵活设置，为了增加两者与卡持部412的作用面积，以改善连接强度，本申请实施例将第一卡接部422的边沿和第二卡接部423的边沿均设置为条形边沿，同时将卡持面412a设置为条形面，且该条形面的延伸方向平行于前述条形边沿的延伸方向。
可选地，在逐渐远离光源板210的方向上，前文所述的卡接间隙的横向尺寸逐渐变小。需要说明的是，这里的横向平行于第一卡接部422与第二卡接部423的相对方向。如此设置后，第一卡接部422和第二卡接部423与卡持部412的配合更加顺畅，使得照明灯具的组装操作更容易实现。
为了简化弹性卡件420的结构，可以将第一卡接部422和第二卡接部423均设置为平板结构，两者形成V形结构。
另外，为了简化弹性卡件420的结构，条形主体部421可以为U形结构。第一卡接部422和第二卡接部423可以位于条形主体部421的内部。进一步地，容纳槽110具有朝向光源板210的顶壁111，该顶壁111可以是平面结构，条形主体部421的顶部与顶壁111相抵靠。此种结构下，弹性卡件420与壳体100之间的抵靠面积较大，使得壳体100可以辅助限制弹性卡件420的变形幅度，防止弹性卡件420受力后发生过大变形而与连接筋410脱离。
如图5-图7所示，另一种实施例中，防变形组件400还包括连接筋410和弹性夹紧件430，弹性夹紧件430具有夹紧间隙，连接筋410的一端与透镜320连接，另一端穿过连接通孔211，并插入前述夹紧间隙，弹性夹紧件430与光源板210相抵靠，并向连接筋410施加夹紧力。此时，防变形组件400与连接筋410依靠彼此之间的摩擦力保持连接，此种连接形式一方面可以满足连接强 度的要求，另一方面可以简化防变形组件400的结构。
进一步地，为了防止弹性夹紧件430在连接筋410插入夹紧间隙内的过程中沿着远离光源板210的方向移动，可以在壳体100上开设限位槽120，弹性夹紧件430的至少一部分位于该限位槽120内。当弹性夹紧件430具有前述的移动趋势时，限位槽120的内表面可以阻挡弹性夹紧件430移动，进而使得连接筋410可以可靠地插入夹紧间隙内。
本申请实施例中，弹性夹紧件430可以包括安装片431、设置于安装片431的第一夹持片432和第二夹持片433，安装片431与光源板210相抵靠，第一夹持片432和第二夹持片433均相对于安装片431向远离光源板210的方向凸出，且两者之间形成夹紧间隙。第一夹持片432和第二夹持片433具有一定的弹性，连接筋410插入夹紧间隙内的过程中，连接筋410向第一夹持片432和第二夹持片433施加足够的作用力，使得两者发生变形，以供连接筋410插入两者之间的夹紧间隙内。由于第一夹持片432和第二夹持片433发生了变形，因此两者可以向连接筋410施加反作用力，进而增大两者与连接筋410之间的摩擦力，达到改善连接可靠性的效果。
上述第一夹持片432和第二夹持片433均可以设置为一个，此时两者与连接筋410的抵靠位置沿着连接筋410的厚度方向相背，进而施加有效的作用力。但是为了进一步增大该作用力，可以将第一夹持片432和第二夹持片433中的至少一者设置为多个，进而通过增加连接点的方式增大第一夹持片432和第二夹持片433与连接筋410之间所形成的夹持力。
为了进一步提升第一夹持片432和第二夹持片433与连接筋410之间所形成的夹持力，可以将第一夹持片432与第二夹持片433错位设置。如图7所示，以第一夹持片432设置为两个，第二夹持片433设置为一个为例，此时，第二夹持片433对应于两个第一夹持片432之间的间隙设置，进而实现错位设置的结构形式。
可选地，在逐渐远离光源板210的方向上，夹紧间隙的横向尺寸逐渐变小， 需要说明的是，这里的横向平行于第一夹持片432和第二夹持片433的相对方向。如此设置后，第一夹持片432和第二夹持片433与连接筋410的配合更加顺畅，使得照明灯具的组装操作更容易实现。
为了保证照明灯具的密封性，壳体100与透镜罩300之间可以设置密封件600，如图8所示，密封件600具有第一密封槽610，该第一密封槽610的槽壁上设置第一密封凸起620，壳体100设置密封筋130，密封筋130插入第一密封槽610，且密封筋130的表面与第一密封凸起620相抵靠。设置第一密封凸起620后，密封筋130插入第一密封槽610的过程中，密封筋130向第一密封凸起620施加作用力，使得第一密封凸起620发生变形，进而在密封筋130与第一密封凸起620之间形成较大的按压力，两者之间的密封性随之提升。
同理地，透镜罩300具有第二密封槽330，密封件600设置于该第二密封槽330内，密封件600的外表面设置第二密封凸起630，第二密封凸起630与第二密封槽330的槽壁相抵靠。密封筋130插入第一密封槽610的过程中，密封筋130撑开密封件600，使得第二密封凸起630被按压在第二密封槽330的槽壁，两者之间可以紧密配合，从而提升照明灯具的密封性。
为了进一步提升密封效果，上述第一密封凸起620和第二密封凸起630中的至少一者可以设置为多个，多个第一密封凸起620，和/或多个第二密封凸起630沿着密封筋130的延伸方向排布。
组装照明灯具时，第二密封槽330内存在空气，将这些空气快速排出第二密封槽330，可以实现密封件600的快速组装，同时还可以保证密封件600与透镜罩300之间的密封性。为此，如图9所示，可以在第二密封槽330的槽壁上开设排气孔340，该排气孔340贯通至第二密封槽330的顶部边缘。第二密封槽330内的空气可以通过该排气孔340排出。当然，该排气孔340的尺寸不宜过大，也不宜过小，过大会对最终的密封效果产生不良影响，过小则会削弱排气效果。
本申请上文实施例中重点描述的是各个实施例之间的不同，各个实施例之 间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
