具体实施方式
如图1所示，本发明的发光二极管路灯包括一壳体10及分别锁固于该壳体10相对两侧并与该壳体10电性连接的二灯体20。一驱动电路模组(图未标)收容于该壳体10内用于驱动灯体20。
请同时参阅图2至图4，该壳体10为四棱台结构，具有相对的底板12与顶板14、围设在四周的前后二侧板(图未标)及左右二安装板16。该壳体10的底板12及顶板14均呈梯形设置，且底板12平行于顶板14。底板12的面积较顶板14大。该底板12的周缘开设有若干通孔121，其上表面一侧向上延伸一螺柱123。一第一螺钉组件30一端固定于顶板14上，另一端与底板12上的螺柱123螺合以防止底板12掉落。该壳体10的前侧板较后侧板小，其后侧板中部装设有一圆柱形的灯座11用于与灯杆(图未示)连接。该壳体10的安装板16连接底板12及顶板14的边缘，自底板12边缘向外、向上倾斜。若干凸柱165自壳体10的内侧面向内凸伸形成，且每一凸柱165中部开设有一具有螺纹的沉头孔1651。若干第二螺钉组件40穿过底板12的通孔121并与这些凸柱165的沉头孔1651配合而将该底板12固定在壳体10上。每一安装板16中部固定有三间隔设置的螺杆161用于固定二灯体20。安装板16相邻的螺杆161间开设有一狭长线孔163。一驱动电路模组30收容在壳体10内。自驱动电路模组延伸的电线(图未示)由线孔163进入灯体20而驱动灯体20。
该第一螺钉组件30具有锁固在顶板14上的第一螺钉31、与底板12上的螺柱123配合的第二螺钉33及连接第一、第二螺钉31、33的纵长金属连接线35。当第二螺钉组件40自壳体10拆卸后，该第一螺钉组件30连接底板12以防止其从高空掉落。
请同时参阅图5及图6，每一第二螺钉组件40包括一螺钉41及与该螺钉41卡合的一金属弹性挡圈43。该螺钉41具有一挡止部、自挡止部中部垂直向下延伸的一圆柱状光杆413及位于光杆413底部的一螺合部。在本发明中，挡止部即为一圆柱状的头部411，螺合部即为一螺纹段415。一收容槽417设置于光杆413及螺纹段415的连接处以收容弹性挡圈43。该弹性挡圈43具有一侧开口的、圆环状的卡环431及该卡环431的开口两侧分别向外延伸的二操作部433。每一操作部433为一倾斜向外延伸的片体。该卡环431的内径较光杆413的直径及螺纹段415的螺纹(图未标)的内径小。该卡环431的外径及螺钉41的头部的直径较底板12的通孔121的内径大。当螺钉41穿过底板12的通孔121后，自一侧挤压卡环431而使该弹性挡圈43收容在收容槽417内而固定在螺钉41上。第二螺钉组件40的螺钉41与沉头孔1651配合而将底板12锁固在壳体10上。当第二螺钉组件40的螺纹段415自沉头孔1651内松脱时，弹性挡圈43及螺钉41的头部411将螺钉41卡置在底板12上以避免其自高空掉落。
请同时参阅图7及图8，所述每一灯体20包括若干发光二极管模组21、一供发光二极管模组21贴设并对其散热的散热器23、若干固定于散热器23上并跨设于发光二极管模组21的反光罩25及一与散热器23配合形成一密闭腔室以将发光二极管模组21及反光罩25围设其内的一灯罩27。
该散热器23由导热性能良好的金属如铜、铝等一体制成。该第一散热器23包括一长方形纵长基板231及自基板231上表面垂直向上延伸的若干散热片233。这些散热片233等间隔均匀分布于基板110上，且沿基板231的横向开设有若干通风槽(图未标)。该基板231下表面中部被平均分成三纵长条形区域，每一条形区域被设置成一平面235以供发光二极管模组21贴设其上。这些平面235呈一定角度设置，如此，贴设于这些平面235上的发光二极管模组21所发出的光线可更好的向壳体10两侧辐射。该基板231的四周开设有若干安装孔(图未标)用于与灯罩27配合。
每一发光二极管模组21包括一纵长矩形的电路板213及若干均匀固定于电路板213一侧面的发光二极管211。这些电路板213的另一侧面贴合于散热器23的基板231的下表面的平面235上。这些发光二极管211位于沿电路板213长度方向延伸的同一直线上，从而将其热量均匀地传导至散热器23上。
每一反光罩25对应一发光二极管模组21。该反光罩25由反光金属制成，包括一矩形框体251及连接框体251四壁的若干反光孔253。每一反光罩25沿其纵向装设有若干螺柱255。若干固定件(图未示)穿过这些螺柱255及发光二极管模组21的电路板213并与散热器23的基板231配合而将每一反光罩25固定于散热器23上。每一反光孔253对应一发光二极管211，用于反射发光二极管211所发出的光线。
所述灯罩27包括一与散热器23配合的矩形框体271、嵌设于框体271的一透明矩形灯盖272及将灯盖272固定于框体271上的一固定架273。
该框体271各边顶部向内凸设有若干凸块2713。每一凸块2713及框体271的四角对应散热器23的安装孔开设有一螺孔2715。若干螺钉(图未示)穿过散热器23的安装孔及这些螺孔2715的上部而将该框体271固定在散热器23上且发光二极管模组21及反光罩25围设于框体271内部。一矩形垫圈60夹设于散热器23及框体271的上端以增加散热器23与框体271的密封性。该框体271各边底部向内延伸有四连接壁(图未标)用以连接固定架273。每一连接壁向内、向下进一步凸伸一承载壁2717用以承载灯盖272。该框体271的侧部具有一接合面(图未标)，该接合面中部开设有与壳体10一侧的螺杆161对应的三螺孔2718，螺孔2718之间开设二线孔2719。每一螺孔2718内固定有一螺母2716(见图2)用于与壳体10的螺杆161配合。自壳体10的驱动电路模组穿出的电线，由框体271的线孔2719进入灯体20内，并与发光二极管模组21电性连接。
该固定架273为一矩形的框架，其四周向上凸伸有若干安装块(图未标)。当灯盖272放置于框体271的承载壁2717后，若干螺钉(图未示)穿过固定架273的安装块及框体271的螺孔2715的下部而将灯盖272稳固的装设在框体271上。此时，一矩形垫圈70夹设于固定架273及框体271的下端以增加固定架273与框体271的密封性。
请再次参阅图1及图2，一矩形片体50夹设于灯体20的接合面及壳体10的安装面16之间。该片体50对应灯体20的螺孔2718开设有三通孔51，对应灯体20的线孔2719开设有二线孔53。壳体10上的螺杆161分别穿过二垫圈55、57、片体50的通孔51穿入框体271的螺孔2718内并与螺孔2718内的螺母2716配合而将灯体20固定于壳体10的安装面16。由于壳体10两侧的安装面16自壳体10顶面14向外倾斜，二灯体20固定在安装面16后自壳体10的安装面16向外倾斜设置，每一散热器23靠近壳体10的一侧边位于相对远离壳体10一侧边的下方，以便于灯体20发射的光线沿不同的方向辐射而增大整个发光二极管路灯照射范围。
