技术领域
本申请涉及照明设备技术领域，尤其涉及一种照明灯具。
背景技术
随着照明技术的快速发展和生活水平的提高，照明灯具已经与人们的生活密不可分。照明灯具包括家居照明灯具、商业照明灯具、工业照明灯具、道路照明灯具、景观照明灯具、特种照明灯具等。各种照明灯具应用于人们生活的各个地方，为人们的生活提供了便利。随着生活质量的不断提升，人们对照明灯具的结构、性能、外观等提出了更高的要求，这就给照明灯具的设计带来了巨大的考验。
目前食品厂、洁净车间和冷库等洁净室内多用洁净三防灯进行照明，这些场所需要洁净三防灯及安装件防水防尘，且不允许在三防灯及安装件上落灰。目前的洁净三防灯通常包括灯体和端盖，灯体通过端盖进行密封。在具体的安装过程中，由于端盖与灯体密封的特殊要求，端盖会凸起于灯体的安装面，导致洁净三防灯在安装至安装基础后，端盖与安装基础接触，灯体与安装基础之间具有间隙，灰尘较容易落在该间隙中，进而导致在三防灯上容易出现落灰。
发明内容
本申请公开一种照明灯具，能够解决洁净室内的照明灯具上容易落灰的问题。
为解决上述技术问题，本申请是这样实现的。
本申请实施例公开一种照明灯具，包括灯体、端盖和弹性密封部，其中：所述灯体具有沿长度方向设置的两个端部，其中至少一个所述端部与所述端盖密封相连，且所述灯体具有用于将所述照明灯具组装于安装基础的安装面，在垂直于所述安装面的方向上，所述端盖部分延伸超出所述安装面；所述弹性密封部设置于所述安装面，在垂直于所述安装面的方向上，所述弹性密封部延伸超出所述安装面及所述端盖，所述弹性密封部可被所述安装基础的表面压迫而产生弹性变形。
本申请采用的技术方案能够达到以下有益效果。
本申请实施例公开的照明灯具中，灯体具有沿长度方向设置的两个端部，其中至少一个端部与端盖密封相连，灯体还具有用于将照明灯具组装于安装基础的安装面，在垂直于安装面的方向上，端盖部分延伸超出安装面，弹性密封部设置于安装面，在垂直于安装面的方向上，弹性密封部延伸超出安装面及端盖，且弹性密封部可被安装基础的表面压迫而产生弹性变形。此种情况下，在照明灯具组装于安装基础的过程后，安装面与安装基础的表面之间形成的间隙能够被弹性密封部封堵，使得灰尘较难进入到该间隙中，从而使得照明灯具上较难出现落灰，进而能够解决洁净室内的照明灯具上容易落灰的问题。

下面结合附图，通过具体的实施例及其应用场景对本申请各个实施例公开的技术方案进行详细地说明。
请参考图1至图7，本申请实施例公开一种照明灯具，所公开的照明灯具包括灯体100、端盖200和弹性密封部300。
其中，灯体100为照明灯具的基础构件，灯体100能够为照明灯具的其他部件提供安装基础，具体地，灯体100具有用于将照明灯具组装于安装基础的安装面110，在照明灯具组装于安装基础的情况下，安装面110与安装基础的表面相对设置，灯体100背离安装面110的一侧具有出光面，灯体100内通常设置有光源模组，光源模组发出的光线能够通过出光面射出。在本申请实施例中，灯体100具有沿长度方向设置的两个端部130，其中至少一个端部130与端盖200密封相连，防止外部杂质(例如水汽和灰尘等)进入到灯体100内，避免杂质影响照明灯具正常工作。
在垂直于安装面110的方向上，端盖200部分延伸超出安装面110，也就是说，端盖200的部分在垂直于安装面110的方向高于安装面110。可选地，端盖200可以包括内端盖210和外端盖220，灯体100的至少一个端部 130与内端盖210密封相连，内端盖210背离灯体100的一侧开设有安装槽211，外端盖220设置于内端盖210，且外端盖220覆盖安装槽211，以使外端盖220与安装槽211能够围合形成安装空间，该安装空间可以用于安装照明灯具的电源组件，同时，该安装空间与灯体100没有连通，工作人员仅需打开外端盖220便可以维修位于安装空间内的电源组件，无需拆除内端盖210与灯体100的密封结构，因此，在方便工作人员维修照明灯具的同时，不会影响照明灯具的密封性能，从而使得照明灯具的稳定性较高。具体地，在垂直于安装面110的方向上，内端盖210部分延伸超出安装面110。
弹性密封部300设置于安装面110，在垂直于安装面110的方向上，弹性密封部300延伸超出安装面110及端盖200，也就是说，弹性密封部300在垂直于安装面110的方向高于安装面110及端盖200，且弹性密封部300可被安装基础的表面压迫而产生弹性变形。
在照明灯具组装于安装基础的过程中，弹性密封部300首先与安装基础的表面接触，照明灯具继续靠近安装基础的表面，在此过程中，弹性密封部300被安装基础的表面压迫而产生弹性变形，直至端盖200与安装基础的表面接触，在端盖200与安装基础的表面接触后，照明灯具较难继续靠近安装基础的表面，此时，安装面110与安装基础的表面之间形成的间隙能够被弹性密封部300封堵，使得灰尘较难进入到该间隙中。
本申请实施例公开的照明灯具中，灯体100具有沿长度方向设置的两个端部130，其中至少一个端部130与端盖200密封相连，灯体100还具有用于将照明灯具组装于安装基础的安装面110，在垂直于安装面110的方向上，端盖200部分延伸超出安装面110，弹性密封部300设置于安装面110，在垂直于安装面110的方向上，弹性密封部300延伸超出安装面110及端盖200，且弹性密封部300可被安装基础的表面压迫而产生弹性变形。此种情况下，在照明灯具组装于安装基础的过程后，安装面110与安装基础的表面之间形成的间隙(后文中均称为间隙)能够被弹性密封部300封堵，使得灰尘较难 进入到该间隙中，从而使得照明灯具上较难出现落灰，进而能够解决洁净室内的照明灯具上容易落灰的问题。
可选地，弹性密封部300可以具有至少两条沿灯体100的长度方向延伸设置的弹性密封条330，至少两条弹性密封条330中任意一者的两端分别延伸至灯体100的两个端部130，且至少两条弹性密封条330可以间隔设置，弹性密封条330可被安装基础的表面压迫而产生弹性变形。此方案中，两条弹性密封条330分别封堵在该间隙的两侧，以使两条弹性密封条330更好地封堵该间隙，使得灰尘更难进入到该间隙中，进而使得照明灯具上更难出现落灰。
进一步地，灯体100的两个端部130均可以密封设置有端盖200，即照明灯具具有两个端盖200，两个端部130分别密封连接有端盖200，弹性密封条330的两端分别与两个端盖200相连，此种情况下，两端分别与两个端盖200相连的弹性密封条330能够更好地封堵间隙，以使弹性密封条330对间隙的封堵效果更好，从而使得灰尘更难进入到该间隙中。
具体地，在弹性密封条330的两端分别与两个端盖200相连后，至少两条弹性密封条330与两个端盖200可以围成封闭轮廓，在照明灯具组装于安装基础的情况下，安装基础、封闭轮廓和安装面110可以围成封闭空间。此种方式无疑能够使得灰尘较难进入到该封闭空间内，以使间隙中较难出现落灰，从而使得照明灯具上较难出现落灰。
在一种可选的实施例中，在第二方向上，安装面110可以具有第一边沿111和第二边沿112，两个弹性密封条330可以分别设置于第一边沿111和第二边沿112，第二方向与灯体100的长度方向垂直。此种情况下，两个弹性密封条330能够封堵在间隙的两侧开口处，避免灰尘落在间隙的两侧开口，以使整个安装面110上较难出现落灰，进一步使间隙中较难出现落灰，从而使得照明灯具上更难出现落灰。
如上文所述，弹性密封部300既要设置于安装面110，还要被安装基础 的表面压迫而产生弹性变形，在弹性变形时可能影响弹性密封部300与安装面110的连接关系，导致弹性密封部300与安装面110分离。基于此，在一种可选的实施例中，弹性密封条330可以包括弹性部310和安装部320，弹性部310与安装部320相连，安装部320可以与安装面110相连，在照明灯具组装于安装基础的情况下，弹性部310与安装基础弹性抵接，弹性部310可被安装基础的表面压迫而产生弹性变形。
在照明灯具组装于安装基础的情况下，弹性部310被安装基础的表面压迫而产生弹性变形，而安装部320较难不会变形，因此较难影响安装部320与安装面110的连接关系，以使安装部320能够稳定地与安装面110相连，避免安装部320与安装面110分离而导致弹性密封条330不能较好地封堵间隙。
具体地，安装部320可以粘接在安装面110上。可选地，安装面110可以开设有卡槽120，安装部320可以包括凸块321和连接部322，凸块321可以通过连接部322与弹性部310相连，凸块321能够与卡槽120卡接配合，以使弹性密封部300卡接于安装面110上，方便工作人员进行装配作业，同时，能够方便工作人员更换弹性密封部300，提高照明灯具的可安装性和可维护性。
可选地，弹性部310可以包括本体部311和弹性延伸部312，安装部320与本体部311相连，安装面110可以具有中间区域和环绕中间区域的外缘区域，在垂直且远离于安装面110的方向上，弹性延伸部312自外缘区域向中间区域倾斜延伸，也就是说，弹性延伸部312自安装面110的边缘向内倾斜延伸。此种情况下，自外缘区域向中间区域倾斜延伸的弹性延伸部312被安装基础的表面压迫时所产生的弹性力较大，能够较为紧密地抵接在安装基础的表面，进一步封堵灰尘进入间隙的通道。
弹性密封部300可以为硅胶件，弹性密封部300还可以为橡胶件，可选地，弹性密封部300可以为三元乙丙橡胶件，因为三元乙丙橡胶件具有耐热、 耐老化和耐腐蚀的优点，同时，三元乙丙橡胶件的成本较低，能够降低照明灯具的成本。
如上文所述，端盖200可以包括内端盖210和外端盖220，可选地，内端盖210与外端盖220可拆卸结合，内端盖210可以与灯体100密封相连。此种情况下，工作人员能够多次拆装内端盖210与外端盖220，工作人员仅需打开外端盖220便可以维修位于内端盖210与外端盖220所形成安装空间内的电源组件，无需拆除内端盖210与灯体100的密封结构，因此，在方便工作人员维修照明灯具的同时，不会影响照明灯具的密封性能，从而使得照明灯具的稳定性较高。
具体地，外端盖220可以扣合于内端盖210，此种设置方式方便工作人员打开外端盖220，从而方便工作人员维修位于安装空间内的电源组件，且无需拆除内端盖210与灯体100的密封结构，维修完成后，工作人员也能便捷地安装外端盖220。当然，外端盖220与内端盖210也可以采用其他结合方式，本申请实施例中对此不做限定。
可选地，内端盖210可以通过螺纹连接件与灯体100的端部130相连，此种连接方式可靠，连接稳定性较高，避免因内端盖210与灯体100出现相对晃动而影响内端盖210与灯体100的密封性能。本申请中并不仅限于内端盖210与灯体100通过螺纹连接件连接的方式结合。
进一步地，螺纹连接件位于安装槽211内，在外端盖220安装前或拆卸后，工作人员可以直接安装或拆卸螺纹连接件，方便工作人员进行照明灯具的安装及拆卸。同时，防止螺纹连接件外露在照明灯具之外，从而避免螺纹连接件影响照明灯具的外观。
可选地，外端盖220可以位于安装槽211内，且外端盖220的外表面可以与安装槽211的槽口共面，以使端盖200的外表面较为平整，使得照明灯具的外观较为美观，从而提升用户的使用体验感。
请参考图8至图16，在本申请实施例中，外端盖220与内端盖210可拆 卸结合，具体地，安装槽211内设置有第一结合部212，外端盖220设置有第二结合部221，第一结合部212可与第二结合部221可拆卸配合，以将外端盖220固定于内端盖210，以使外端盖220与安装槽211能够围合形成安装空间，该安装空间可以用于安装电源组件。
本申请实施例公开的照明灯具中，由于灯体100与内端盖210密封相连，且电源组件位于内端盖210与外端盖220形成的安装空间内，因此，该安装空间与灯体100没有连通，工作人员仅需打开外端盖220便可以维修位于安装空间内的电源组件，无需拆除内端盖210与灯体100的密封结构，避免照明灯具每次维修后均需要重新设置密封结构，进而能够解决三防灯维修繁琐不便的问题。
可选地，第一结合部212可以为第一卡接部，第二结合部221可以为第二卡接部，外端盖220可相对安装槽211的槽口沿第一方向和第二方向平行滑动，第一方向与第二方向相反，也就是说，第一方向和第二方向均与安装槽211的槽口平行，在外端盖220沿第一方向或第二方向滑动时，外端盖220平行于安装槽211的槽口滑动。在外端盖220沿第一方向滑动的情况下，外端盖220与内端盖210通过第一结合部212与第二结合部221的卡接配合相连，也可以理解为，第一结合部212与第二结合部221在第一方向上卡接配合，且外端盖220覆盖安装槽211；在外端盖220沿第二方向滑动的情况下，第一结合部212与第二结合部221分离。
在外端盖220需要组装至内端盖210时，工作人员可以推动外端盖220沿第一方向滑动，在外端盖220沿第一方向滑动的过程中，第一结合部212首先与第二结合部221接触，随着外端盖220的继续滑动，直至第一结合部212与第二结合部221卡接配合后，外端盖220停止滑动，此时，外端盖220通过第一结合部212与第二结合部221的卡接配合扣合于内端盖210，且外端盖220覆盖安装槽211。在外端盖220需要与内端盖210需要分离时，也就是从内端盖210上拆卸外端盖220时，工作人员可以推动外端盖220沿第 二方向滑动，在外端盖220沿第二方向滑动后，第一结合部212与第二结合部221分离，此时，外端盖220与内端盖210能够分离，实现从内端盖210上拆卸外端盖220的需求。
本申请实施例公开的照明灯具中，安装槽211内设置有第一结合部212，外端盖220设置有第二结合部221，第一结合部212可与第二结合部221卡接配合，且外端盖220可相对安装槽211的槽口沿第一方向和第二方向平行滑动，第一方向与第二方向相反，在外端盖220沿第一方向滑动的情况下，外端盖220与内端盖210通过第一结合部212与第二结合部221的卡接配合相连，且外端盖220覆盖安装槽211；在外端盖220沿第二方向滑动的情况下，第一结合部212与第二结合部221分离。此种情况下，工作人员仅需推动外端盖220沿第一方向或第二方向滑动，便可以实现外端盖220的安装与拆卸，且由于外端盖220相对安装槽211的槽口沿第一方向和第二方向平行滑动，使得工作人员仅需施加推力，无需较多的操作过程，更不用借助工具来辅助，便能够安装或拆卸外端盖220，从而方便工作人员拆装外端盖220，进而能够解决照明灯具拆装不便的问题。
为了进一步方便工作人员拆装外端盖220，可选地，安装槽211的槽口可以倾斜设置，即安装槽211的槽口不平行于竖直方向，也不垂直于竖直方向，安装槽211的槽口倾斜设置后，外端盖220在拆装时倾斜滑动，便于工作人员施加推动力，以使工作人员能够较为轻松地拆装外端盖220，从而能够进一步方便工作人员拆装外端盖220。需要说明的是，竖直方向为重力方向。
具体的，在第一方向上，安装槽211的槽口可以向着靠近灯体100的方向倾斜设置。在该照明灯具安装至安装基础后，在工作人员拆装外端盖220时，此种倾斜设置的方式能够使得工作人员直接观察外端盖220与内端盖210的分离情况，且能够直观看到工作人员手动驱动的位置，从而方便工作人员操作。
如上文所述，安装槽211内设置有第一结合部212，外端盖220设置有第二结合部221，第一结合部212可与第二结合部221卡接配合，以使外端盖220通过第一结合部212与第二结合部221的卡接配合扣合于内端盖210。可选地，第一结合部212可以包括自安装槽211的内侧壁或底壁向第二方向延伸的第一延伸部2121；外端盖220可以包括本体部222和第二结合部221，第二结合部221可以包括自本体部222向着内端盖210延伸的第二延伸部2211，和自第二延伸部2211向第一方向延伸的第三延伸部2212；第一延伸部2121背离外端盖220的一侧和第三延伸部2212朝向本体部222的一侧中，一者可以设置有第一凸起2122或凹槽2123，另一者可以设置有第二凸起2213，且第三延伸部2212与本体部222能够形成滑动槽223。
在外端盖220需要组装至内端盖210时，工作人员可以推动外端盖220沿第一方向滑动，在外端盖220沿第一方向滑动的过程中，第一延伸部2121沿第二方向伸入滑动槽223内，且第一延伸部2121与滑动槽223滑动配合，随着外端盖220的继续滑动，第二凸起2213与第一凸起2122或凹槽2123卡接配合，此时，外端盖220停止滑动，外端盖220通过第二凸起2213与第一凸起2122或凹槽2123的卡接配合扣合于内端盖210。在外端盖220需要与内端盖210需要分离时，也就是从内端盖210上拆卸外端盖220时，工作人员可以推动外端盖220沿第二方向滑动，此时，第一延伸部2121与滑动槽223滑动配合，且第一延伸部2121沿第一方向逐渐滑出滑动槽223，随着外端盖220的继续滑动，第二凸起2213与第一凸起2122或凹槽2123分离，外端盖220与内端盖210能够分离，实现从内端盖210上拆卸外端盖220的需求。
此种第一结合部212和第二结合部221的结构均较为简单，且卡接可靠，同时，在拆装过程中，滑动槽223能够对第一延伸部2121起到导向的作用，以使外端盖220在安装后的位置较为准确。
为了使外端盖220能够较为可靠地扣合于内端盖210，避免外端盖220 从内端盖210上掉落。基于此，在一种可选的实施例中，第一结合部212和第二结合部221的数量可以均为多个，且多个第一结合部212与多个第二结合部221可以一一对应地设置。多个第一结合部212和第二结合部221卡接后，无疑能够使外端盖220能够较为可靠地扣合于内端盖210，以使外端盖220与内端盖210连接可靠，避免外端盖220从内端盖210上掉落。
进一步地，第一结合部212的数量可以为三个，三个第一结合部212可以成三角形分布。此种分布方式能够使得第一结合部212分布较为均匀，从而使得外端盖220所受到的力较为均匀，同时，有三角形具有稳定性，因此，三角形分布的第一结合部212在与相对应的第二结合部221卡接口，能够进一步使得外端盖220可靠地扣合于内端盖210，以使外端盖220与内端盖210连接更加可靠。
在工作人员推动外端盖220沿第一方向或第二方向滑动的过程中，工作人员可能将外端盖220压变形或压碎。基于此，在一种可选的实施例中，安装槽211的底壁可以设置有第一支撑部213，外端盖220可以设置有第二支撑部225，在外端盖220与内端盖210相连的情况下，第一支撑部213和第二支撑部225相抵接。在工作人员推动外端盖220沿第一方向或第二方向滑动的过程中，第一支撑部213和第二支撑部225支撑外端盖220，避免工作人员可能将外端盖220压变形或压碎，从而提高照明灯具的可靠性。
外端盖220通常通过注塑成型，且为板状，此种结构的外端盖220容易变形，为了防止此种结构的外端盖220容易变形，可选地，外端盖220可以设置有加强筋224，加强筋224能够加强外端盖220的强度，避免外端盖220容易变形，从而使得外端盖220能够紧凑地安装至内端盖210，且较好地覆盖安装槽211。
进一步地，加强筋224可以位于外端盖220朝向内端盖210的一侧，避免加强筋224外露在照明灯具之外，以使照明灯具的外观较为美观，从而提升用户体验。
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。
