 本发明的实施方式
在下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
参照图1-8，机场嵌入式助航灯，包括灯具设备主体，灯具设备主体包括灯具上盖1、压板5、发光装置、灯腔12、上盖上表面14和上盖下表面16，灯具上盖1上开设有至少一个棱镜2，棱镜2处布置有灯具内盖3，灯具上盖1中部设置有灯具上盖结构筋15，发光装置安装在灯具上盖结构筋15的斜面上，压板5、LED驱动PCB6安装在上盖下表面16上，灯具上盖结构筋15竖截面为倒梯形，灯具上盖1的底部开设有密封圈槽19，密封圈槽19内布置有灯体密封圈13，灯腔12通过灯具外壳安装螺栓11安装并固定在灯具上盖1上，灯具内盖3为光学灯具内盖，其外形结构为五角灯具内盖，材质为玻璃，灯具内盖3包括光出射面31、光入射面32、棱镜面33、粘胶面一34、粘胶面二35、粘胶面四36和粘胶面五37，光出射面31、粘胶面一34、粘胶面二35、粘胶面四36、粘胶面五37为模压成型的光学面，光入射面32为研磨抛光的光学面，灯具内盖3的光入射面32为光入射面，光出射面31为光出射面,光出射面31与上盖上表面14组成灯具设备上表面，灯具内盖3的粘胶面一34、粘胶面二35、粘胶面四36、粘胶面五37为安装面，粘胶面一34、粘胶面二35、粘胶面四36、粘胶面五37通过密封胶粘接在灯具上盖棱镜2处，的发光装置4包括反射板41、LED板42、反射板基座43，反射板41与反射板基座43呈一体式结构，且反射板基座43通过发光装置安装螺栓8与LED板42连接，并固定设置在灯具上盖结构筋15斜面上，LED板42为铝基板，与灯具上盖1连接，且连接面涂抹导热硅脂，压板5通过棱镜支撑板安装螺栓9固定在上盖下表面16，且压板5与灯具内盖3的棱镜面33之间布置有厚度不超过1mm的棱镜垫片7，LED驱动PCB6通过LED驱动PCB安装螺栓10固定上盖下表面16上。
棱镜3下部布置了机场灯具出光口标记22。机场灯具出光口标记22包含了该出光口的内倾角方向和颜色信息，在从灯具外可通过窗口2，透过棱镜3看到该标记。该标记可为贴纸、涂刷颜料、钢印等工艺或材质。
实施例：灯具上盖1表面在机场跑道的地表外，与飞机轮胎有直接接触，灯具上盖1优选为铝合金材质，开设有棱镜2，棱镜2的数量为1个到6个不等，一个棱镜2对应一个灯具内盖3和一个光学组件41，发光装置41安装在灯具上盖结构筋15的斜面上，以使发光装置4发出的光通过灯具内盖3从棱镜射出。
五角的灯具内盖3作为机场嵌入式灯具的灯具内盖3，通过五角的灯具内盖3的折射和反射特性，光传递效率高，五角的灯具内盖3作为机场嵌入式灯具的灯具内盖3，外形结构简单，体积小，为灯具内部留出更多空间。
灯具内盖3既为发光装置4，也为结构部件，灯具内盖3与灯具上盖1的连接优选采用密封胶粘接，该密封胶具有结构性能和密封性能，为保证灯具结构强度，灯具内盖3优选采用玻璃铸造工艺制成。
灯具内盖3共有7个面，包括光出射面31、光入射面32、棱镜面33、粘胶面一34、粘胶面二35、粘胶面四36和粘胶面五37，其中，光出射面31、粘胶面一34、粘胶面二35、粘胶面四36和粘胶面五37对表面强度要求较高，优选采用光学模压成型，光入射面32、棱镜面33对表面结构要求较低，其中光入射面32优选采用光学研磨和抛光成型。
反射板基座43和反射板41优选为塑料材质，反射板41与反射板基座43呈一体式结构，反射板41的表面优选采用光学镀膜，通过发光装置安装螺栓8将反射板基座43与LED板43压紧并固定在灯具内盖3的灯具上盖结构筋15斜面上，LED板42优选为铝基板，其与上盖1连接的一面涂抹导热硅脂。
灯具上盖下表面16设置有压板安装螺孔，为棱镜支撑板安装螺栓9的安装螺孔，压板5通过棱镜支撑板安装螺栓9固定在安装好灯具内盖2、发光装置4的灯具上盖下表面16上，棱镜支撑架5与灯具内盖3的棱镜面33之间布置有厚度不超过1mm的橡胶棱镜垫片7，橡胶棱镜垫片7被压板5压实，压板5对灯具内盖有支撑作用。
灯具上盖下表面16设置有驱动PCB安装孔18，为LED驱动PCB安装螺栓10的安装螺孔，LED驱动PCB6通过LED驱动PCB安装螺栓10固定在安装好灯具内盖3、发光装置4、压板5的灯具上盖下表面16上。
灯具上盖下表面16设置有灯体安装孔17，为灯具外壳安装螺栓11的安装螺孔，灯具上盖1的下表面16开设有密封圈槽19，密封圈槽19内布置有灯体密封圈13，灯腔12通过灯具外壳安装螺栓11与安装灯具内盖3、发光装置4、压板5和LED驱动PCB6的灯具上盖1固定并组成完整的灯具，固定后密封圈槽19内的灯体密封圈13产生0.2-0.5mm的形变。
灯具设备通过灯具安装孔20安装到机场跑道灯具底座内，灯具安装孔数量2个到6个不等。
采用本发明的结构，由于发光装置4安装在灯具灯具上盖结构筋15内，灯具内盖3各个面通过密封硅胶连接，灯具内盖3外形为五角灯具内盖，结构简单，体积小，灯具内盖3与灯具上盖1之间通过密封硅胶密封连接，相比传统的玻璃胶套密封，密封性更好，稳定性更高。
发光装置4发出的光通过五角的灯具内盖3的折射和全反射，光线可低损耗地从有限面积的棱镜发出，实现灯具对道面的低凸起，相比传统灯具6.3mm-12.5mm的凸起高度，在满足机场运行的要求前提下，本发明的灯具设备凸起高度可达4mm以内，降低灯具对飞机起降、滑行造成的影响。
本发明的结构由于其发光装置4和LED驱动PCB6都是直接安装并连接到灯具上盖1，通过铝合金的灯具上盖1具有良好的导热性能，因此灯具不需要额外增加导热装置，可直接通过灯具外壳传递热量，有利于延长灯具设备的使用寿命，并且简化了结构。
本发明的结构中，灯具内盖3、发光装置4的安装及组合结构使上盖有充足的空间设置灯具上盖结构筋15，灯具上盖结构筋15为竖截面呈倒梯形，截面积大，有效增强了整体灯具荷载性能，本发明的灯具上盖结构筋15不局限于倒梯形，只要在灯具上盖1内设置能安装发光装置4的斜面上，使得发光装置4发出的光能顺利通过灯具内盖3并从灯具的棱镜2射出，都包含在本发明的保护范围之内。
本发明描述的机场灯具出光口标记22，设置在棱镜下部，也就是灯具内部，相比于标记设置在灯具外部，降低了灯具户外运行可能造成的标记损坏或灭失风险，本发明保护的是机场灯具出光口标记22放入灯具内部的实施方法，不限于标记本身的工艺或材质。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、 “右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“ 顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的设备或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
