在本实施例中，安装端口100具备安装端口外缘1000，灯体1具备一圈凸出于安装端口外缘1000的抵接环12，其中，安装腔10用于安置反光杯3，抵接环12用于与面板4配合夹设密封圈2，密封圈2可以如图1所示设置为周向围绕安装端口100的垫圈，并且在抵接环12上设置有环槽122，并将垫圈设置在环槽122中，这样可以避免面板4与灯体1夹设垫圈时垫圈发生不必要的位移。
如图3所示，抵接环12具备轴向围绕安装端口100的安装端口内缘120，安装端口内缘120凸出设置有一圈抵接台阶1200，抵接台阶1200具备用于支撑反光杯3且朝向安装端口100的承载环面1200a，其中，安装端口内缘120及承载环面1200a可以均设置为圆形，也可以根据安装端口100的形状对应设置。
图3所示的承载环面1200a与安装端口内缘120相互垂直并共同形成了一个用于固定反光杯3的抵接台阶1200，两者之间也可以设置为其他角度，对应于该抵接台阶1200，反光杯3具备如图1所示的出光腔口30，出光腔口30具备出光腔口外缘300，自出光腔口外缘300凸出设置有一圈周向围绕出光腔口30的支撑环32，该抵接台阶1200可以如图3所示与支撑环32形状吻合且能够紧密扣合，也可以是将支撑环32设置为与抵接台阶1200的两个表面相互抵接但彼此之间存在缝隙，只要能够限制反光杯3沿竖直方向移动即可，通过如此设置，可以简化安装反光杯3的过程。出光腔口30的朝向与安装端口100相同，保证正常出光。
在本实施例中，为实现反光杯3能够为面板4提供缓冲作用，反光杯3由弹性材料制成，该弹性材料可以是橡胶，也可以是弹性较好的塑料等。在本实施例中，将支撑环32与密封圈2设置为均在安装端口的朝向方向上超过 安装端口100，这样当面板4覆盖抵接环12时，可以同时挤压密封圈2及支撑环32。
本申请采用密封圈和具备支撑环的反光杯，并由支撑环与密封圈共同支撑面板以在面板和灯体之间形成缓冲空间，降低了面板受压破损的风险。
在本实施例中，还包括光源组件5，光源组件5具备出光面50和围绕出光面50的光源组件侧面52，反光杯3具备与出光腔口30沿安装端口的朝向方向相对的入光腔口34，使反光杯3形成一个贯通的反光腔，将出光面50朝向入光腔口34，这样出光面50射出的光线可以进入反光杯3并被反光杯3聚拢。
为实现光源组件5的出光角度可调整的技术效果，光源组件5具备光源组件侧面52凸出的转轴54，转轴54可以设置为如图1所示的在光源组件侧面52凸出一个转轴54，也可以在光源组件侧面52两个相互背离的面分别凸出一个转轴54等，能够与安装腔10内的转轴配合组件1002配合并使转轴54旋转以改变光源组件5的光轴与安装端口的朝向方向之间的夹角即可。转轴54和转轴配合组件1002可以设置为圆柱轴和圆孔的配合结构，也可以设置为轴芯和配合轴承的结构等。
在本实施例中，如图4所示，转轴配合组件1002设置为能够扣合的U形承接槽1002a和阻尼件1002b，U形承接槽1002a和阻尼件1002b扣合转轴54后，由阻尼件1002b对转轴54提供转动阻力，这样可以在光源组件5的出光方向调整完毕后固定该出光方向，在本实施例中，使阻尼件1002b能够有效提供转动阻力，U形承接槽1002a的深度不超过转轴54的直径，这样可以将阻尼件1002b设置为如图1所示的倒U形或其他有利于提供转动阻力的形状。在本实施例中，阻尼件1002b可以设置为具备粗糙摩擦面的固定件，也可以是在朝向转轴54的一面具备凸出的咬合齿，通过咬合齿提供摩擦力。
为便于调整转轴54的旋转，在本实施例中，如图1所示，灯体1具备周向围绕安装端口100的外周面14，安装腔10具备内周面102，为使外部操作 能够到达内部的转轴54，灯体1具备贯穿外周面14和内周面102的调整孔16，图4所示的实施例中，由于转轴54设置在U形承接槽1002a内，因此调整孔16的开口设置在U形承接槽1002a的侧壁上，若转轴54设置在其他位置，调整孔16对应改变位置即可，与转轴54共轴设置即可。
为实现调整转轴54的转动姿态，如图4所示，本申请实施例所述的地埋灯还包括调整杆6，调整杆6用于贯穿调整孔16并带动转轴54转动，在本实施例中，转轴54可以开设有与其共轴的六角孔，将调整杆6的一端设置为对应的六角形，这样将调整杆6插入六角孔，即可带动其转动，也可以将调整杆6设置为具备夹持部，能够带动转轴54转动即可。
由于在灯体1上开设调整孔16会破坏灯体1的防水性，为解决这一问题，在本实施例中，如图4所示，灯体1还包括调整孔防水件18，调整孔防水件18设置于调整杆6与调整孔16之间的间隙内并在周向上填满此间隙，调整孔防水件18可以是橡胶圈，也可以是发泡塑料，能够阻碍外界水分自调整孔16进入灯体1即可。
为便于灯体1安装，在本实施例中，如图1所示，还包括预埋件7和固定件8，预埋件7具备预埋腔70，预埋腔70具备开口方向为安装端口的朝向方向的预埋开口700，以将地埋灯安装至地面为例，可以先在地面挖一个足够大的洞，先将预埋件7埋入洞中，预埋开口700暴露在地面，再将灯体1等结构自预埋开口700安装进入预埋腔70并固定，再将固定件8通过螺栓固定或粘接固定等方向固定于灯体1并将面板4压设固定在灯体1上，压紧力朝向安装端口100，同时固定件8向远离轴线的方向延伸并覆盖预埋开口700，这样可以通过一次安装同时实现固定面板4和遮蔽预埋开口700两个目的，便于安装，固定件8可以是如图1所示的固定环，固定环在覆盖预埋开口700的同时覆盖面板4的周缘，也可以将固定件8设置为透明罩，能够同时压设面板4和遮蔽预埋开口700即可，这样在保证了防水性能的同时可以简化结构。
在本实施例中，为给光源组件供电，还包括电源9，电源9可以如图1所示设置于灯体1的底部，也可以设置在预埋腔70的其他部分。
综上，本申请采用密封圈和具备支撑环的反光杯，并由支撑环与密封圈共同支撑面板以在面板和灯体之间形成缓冲空间，降低了面板受压破损的风险。
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。
