具体实施方式
下面将结合具体实施例及附图对本发明LED路灯作进一步详细描述。
请参考图1和图2，一较佳实施例中，本发明的LED路灯主要包括电器腔体10、两根支撑管20、端盖30、灯臂40和多个平行设置的LED光源模块50。其中，电器腔体10主要用于收容和保护路灯电源模块60、固定支撑管20和灯臂40。电源模块60主要用于为LED光源模块50供电，其可包括例如但不限于驱动电源、防雷器等。
支撑管20为长条形中空管状，优选的采用具有一定弯折的铝质型材，其包括光源模块固定部23及分别位于光源模块固定部23两端的定位端21和活动端22。定位端21固定于电器腔体10上，活动端22与端盖30固定连接，两根支撑管20平行设置成横梁状，电器腔体10、两根支撑管20和端盖30连接起来大体呈长方体状。多个LED光源模块50呈桥接形式并排固定于两根支撑管20的光源模块固定部之间，且，各LED光源模块50之间留有大于3mm小于20mm的空隙。如此，光源模块之间形成空气对流利于散热，且在对其中一个光源模块进行维护时不影响其他模块，当需要通过增加或减少LED光源模块50以达到增大或降低路灯功率的目的时，只要更换加长或截短的支撑管20并增加和减少相应的LED光源模块即可，因此可以以极低的制造和维护成本实现路灯的功率系列化。支撑管20为具有一定弯折的型材，强度高、稳定性强。
请参见图3，本实施例中，每个LED光源模块50中主要包括一长方形透光板51、一保护板52、一电路板53和一散热器54。透光板51上表面形成有多个透镜511，下表面形成有至少两个定位柱5114。保护板52紧紧贴敷于透光板上，其上形成有与透镜匹配的通孔，该保护板52用于保护透镜511、且能够加强对LED光源模块50的防水功能及抗冲击效果。电路板53固定于透光板下方，其上设置有与多个透镜对应的LED光源。本实施例中，电路板53与散热器54上分别形成有与透光板51上定位柱5114相适配第一定位孔533和第二定位孔547，且通过定位柱5114穿过第一定位孔533后再插入散热器54上的第二定位孔547并依次扣紧，既能够保证透光板51上的透镜511和LED光源准确定位，又能通过固定螺丝将透光板51、保护板52、电路板53和散热器54紧固在一起。
优选的，散热器54主要采用具有一定弯折的铝质型材，其包括一个紧紧贴敷于电路板下表面的、呈长方形的第一传热板541、从第一传热板541下表面的两侧边（指第一传热板的不与支撑管20连接的长边）基本垂直于第一传热板一体延伸而出的两块第二传热板542、以及将所述两块第二传热板的末端连接起来的第三传热板543。其中第二传热板542的外侧表面呈波浪起伏状，且第二传热板542的长度小于第一传热板541，从而第三传热板543遮盖部分第一传热板541，使第一传热板541的两端呈伸出散热器54的状态，此结构的散热器有利于提高散热效率、加强散热器的强度，并有效的防止灰尘、树叶、砂石、鸟屎长期累积在散热器上。由于多个LED光源模块50之间均留有空隙，上述空隙在不同的LED光源模块50之间形成对流槽，允许空气进入第二传热板之间，从而可以利用热空气上升冷空气补充的烟囱效应让空气产生对流直接将第二传热板和第三传热板上的热量带走，从而提高散热效果。此外，第二传热板上的波纹状起伏增大了传热板的有效散热面积，散热效率更高。
对应的，请同时参见图1和4，支撑管20背向LED光源模块50的侧壁呈圆弧形，其朝向LED光源模块50的一侧具有一与散热器54端部对应的平面25，平面25的边缘形成有用于放置及固定伸出散热器54的第一传热板541的台阶26，从而支撑管20也具有散热的作用，提高路灯的散热效果。所述平面25上还形成有一大致呈管状的、用以穿插导线的过线管腔24，该过线管腔24的两端设有防水硅胶塞，在防水硅胶塞上形成有多个用于穿插导线的过线孔，LED光源模块50的电源线穿过过线管腔24，从防水硅胶塞的过线孔穿出后接入电器腔体11的电源盒体，并与置于电源盒体内的电源模块的输出端连接。
透光板51的两侧垂直于透光板一体延伸而出两块护板512，散热器54的第一传热板541上形成与所述护板相对应的凹槽5411，透光板51和保护板52的对应位置上形成有多个固定孔513，电路板53两侧边上形成有多个与透光板上固定孔对应的弧形缺口531，电路板53外周围套有形状与电路板四边形状对应的防水硅胶55；所述保护板和透光板依次扣在电路板上，从而，可通过固定螺丝将保护板52、透光板51和电路板53固定在第一传热板541上。
电路板53大体呈长方形，其上电连接有多个与透镜511对应的LED光源。电路板53和第一传热板541上分别开有相对的线孔532、544，电路板53的电源线穿过线孔532、544与外部的连线器545相连。
为达到防水密封的目的，电路板53外周围套有防水硅胶55，电源线与线孔532、544之间设置有硅胶塞56。当透光板51和电路板53被固定螺丝固定在散热器54上时，防水硅胶55被紧紧挤压在透光板51、护板512、电路板53和散热器54之间，此时防水硅胶55会因受压产生变形，将透光板51、护板512 、电路板53和散热器54之间的缝隙密封起来，保证电路板53和LED光源不会受潮，确保光源寿命。
电器腔体10背向LED光源模块50出光方向上设置有一开口，在该开口的内形成有大体呈长方形的、用于容置电源模块60的电源盒体11。电源盒体11的外侧分别靠近电器腔体相对的两个侧壁处形成有可供两个支撑管的定位端插入并固定的两个容置槽12，换句话说，电源盒体11两侧边与电器腔体外壳之间形成有两个容置槽12。支撑管20的定位端21插入容置槽12，两者通过一L形固定片122和固定螺丝121固定连接在一起。
电器腔体朝向LED光源模块50出光方向的外壁上形成有用于固定感应器的凹槽状的感应腔18，该感应腔的腔口处可分离地固定一用于遮挡感应腔18的感应腔盖14用于感应腔18防水的硅胶圈。
电器腔体10的开口处设置有一电源腔盖15，该电源腔盖15与电器腔体10的靠近LED光源模块50的前壁的末端处通过铰链通过铰链结构16相连，且电源腔盖合上后遮挡所述电源盒体11及支撑管20的定位端21。电源腔盖15与电源盒体11对应的位置上形成有凸沿，凸沿上套设有防水硅胶圈，当电源腔盖15合上后，凸沿与电源盒体11周边相对，防水硅胶圈密封两者之间的缝隙，可有效防止电源进水或受潮。
电源腔盖15上还设有可安装光控器的圆形接口151，接口151具有一外凸的圆环边，起结构加强和防水作用，接口内装有防水硅胶垫片。不装光控器时，防水硅胶垫片上装有光控孔盖152，光控孔盖152通过四颗螺丝压到防水硅胶垫片后锁紧到灯体10上，起外部防护和防水作用。安装光控器时,先把光控孔盖152去除，再把光控器的底座通过螺丝安装到电源腔盖15上。此接口设计利于灯具在增加光控功能时能更方便快捷地实现，增加灯体的通用性。所述的光控器是指可根据环境光亮度的高低自动切断或接通路灯电源模块输入端的、具有开关功能的光控器。
请参见图5和图6，电器腔体10的内部形成有一大致呈腰型的用于固定水准泡19的凸台101，该凸台101靠近电源盒体11远离LED光源模块50的一个侧壁外部；另在电器腔体底部且靠近的灯臂腔体两侧各有一个漏水孔102。工作人员在装设时，可通过水准泡19准确识别安装水平度。
灯臂40包括一用于插入并固定路灯灯杆的中空圆管43，圆管43侧壁上靠近圆管43的一端向外延伸出两个凸管41，两个凸管41的中心轴位于一条直线上。凸管41的中心轴（管壁所在面为一线段绕中心轴旋转形成）优选地与圆管43的中心轴垂直交叉。灯臂40还包括一与凸管41平行设置的调节块42,调节块42与圆管43侧壁相连，且两端延伸出圆管43外周。灯臂40还包括一大体呈四分之三圆环的壳体44，以下为方便描述，定义该圆环的的剩余四分之一缺口为缺口，圆环两端为开口。壳体44以凸管41为中心轴设置，且其上形成有与圆管43端部对应的通孔，圆管43一端从该通孔伸出，另一端朝向壳体44的缺口并与壳体44内壁相连。调节块42设置在圆管43与壳体44内壁之间，并与圆管43与壳体44相连。凸管41外壁优选的也与壳体44内壁相连。壳体44使得灯臂40结构坚固，不易损坏，外观更美观，易与电器腔体外观呈一体状。
电源盒体10的远离LED光源模块50的侧壁111的外侧形成有一灯臂腔体13，灯臂40可转动连接于灯臂腔体13上。该灯臂腔体13包括两个相对称的、从侧壁111的外表面一体延伸而出两块灯臂固定板131。固定板131外形与壳体44相配套，其上对应凸管41的位置上形成一大体呈扇形的收容滑槽，灯臂40可沿该收容滑槽插入固定板131之间，并将凸管限位于滑槽末端（即扇形圆角处）。固定板131上还形成有与调节块42对应的弧形槽口132，弧形槽口位于滑槽内且靠近滑槽边缘。调节块42插入该弧形槽口132，并可在弧形槽口132内滑动。灯臂40可以以凸管41为中心相对电器腔体10旋转，旋转的范围受弧形槽口132限制。两个调节螺栓133穿过弧形槽口132与调节块42固定连接，从而固定灯臂与电源腔体之间的角度。通过拨动调节螺栓133在弧形槽口132的位置，可调节灯臂的角度。特别的，上述壳体、大体呈扇形的收容滑槽均在灯臂与电器腔体的角度调节中起到一定的限位作用。
可以理解的，上文中的螺栓固定优选使用垫块或垫片，且垫块或垫片与安装面接触的面优选的适配安装面，从而增加连接强度。
虽然对本发明的描述是结合以上具体实施例进行的，但是，熟悉本技术领域的人员能够根据上述的内容进行许多替换、修改和变化、是显而易见的。因此，所有这样的替代、改进和变化都包括在附后的权利要求的精神和范围内。
