本发明涉及照明路灯，特别涉及一种固定 LED 照明模块的框架及 LED 照明模块角度均可调节的路灯灯头。
背景技术
LED路灯作为半导体照明的主要应用，具有使用寿命长，雾穿透力强的优点，更重要的是比传统路灯更节能。
由于LED自身存在光学性能上的不足，如果将LED光源设置在传统的路灯灯具上，则只能是在制造时，根据特定道路的照明情况进行配光设计，即设计好每个或每组LED的光照指向，使其照射路面的不同区域，获得整体的照明效果；上述路灯只能适应特定的路面照明，每个或每组LED的指向是固定的，因此不能够进行角度调节以适应其它道路的照明，具有一定的局限性。
 技术解决方案
本发明针对现有技术的不足，提供了一种可根据道路情况调节出光角度的 LED 路灯灯头。
本发明的技术方案是这样实现的：
一种 LED 路灯灯头，该灯头包括前段的电源盒，中段的灯架及尾段的尾盖，所述的灯架包括有可转动的框架，框架连接有限制框架转动的框架定位装置，在框架内并排安装有多个 LED 照明模块，所述的 LED 照明模块与框架转动连接，在框架上设有限制 LED 照明模块转动的模块定位装置。
作为优选，所述的灯架包括沿灯架中心线左右对称的两个框架及连接两个框架的连接件，所述的连接件的前后两端分别与电源盒、尾盖固定连接，所述框架的内侧与连接件转动配合连接，框架外侧与框架定位装置相连。
作为优选，所述的框架包括左侧板、右侧板及连接左右两侧板的前侧板、后侧板， LED 照明模块两端与所述的左侧板、右侧板转动连接，在左侧板上沿同一直线上设有多个用以安装 LED 照明模块的轴孔，在右侧板上与左侧板上轴孔相对应位置处设有多个可供 LED 照明模块上导线穿过的导线孔，所述的右侧板呈弧形，且在前侧板上与右侧板连接处的上下两端均开有凹槽，在后侧板上与右侧板连接处的上下两端也开设有凹槽。
所述的连接件为一中空型材，其包括有底板，在底板的两端设有左右对称的两个与框架的右侧板形状匹配的用以托住右侧板并使右侧板在其内部旋转的托板，在托板上设有与框架右侧板上导线孔相对应的孔，底板与两托板形成一用以容纳导线的空腔，在托板的上下两端沿自身长度方向开设有定位槽，在定位槽内穿设有支撑杆，支撑杆的两端分别连接电源盒与尾盖。框架的右侧板可绕连接件的托板转动，前侧板、后侧板上凹槽的宽度及深度决定了框架右侧板的转动角度。
作为优选，在 LED 照明模块上的右端设有球头，从球头内引出有导线，在 LED 照明模块上的左端固设有一圆环，在圆环外圆周的上下两端各设有一弹性凸齿，所述的圆环连接模块定位装置。球头可以自如旋转，满足 LED 照明模块周向转动调节的需要，并且停止旋转时借助模块定位装置定位。
作为优选，所述的模块定位装置包括卡环，所述的卡环套接在圆环外，在卡环中部设有一横挡，在横挡中部设有轴头，所述的轴头插置在左侧板上的轴孔内，在卡环内周上下两端各设有一排内齿，所述的弹性凸齿与所述的内齿啮合，卡环与左侧板通过滑块、滑轨结构滑动连接，且卡环周向固定在左侧板上，当弹性凸齿与内齿间受到较大作用力时，弹性凸齿可相对内齿滑动。 LED 照明模块通过一圆环插置在上述周向固定的卡环内，圆环外周上的弹性凸齿与卡环内周的内齿啮合，当需要调整单个 LED 照明模块的光照角度时，可转动 LED 照明模块，使得弹性凸齿受力在内齿上发生滑动，从内齿间的某个齿槽内移动到另外的齿槽内，当调整好角度时，转动停止，弹性凸齿卡在内齿间的齿槽内，使 LED 照明模块停留在了相应的位置，再次调整时可重复上述操作； 初始状态时，需将卡环逐个安装到左侧板上并滑动到相应位置，然后将 LED 照明模块上的圆环插置在卡环内周内，为防止圆环插入过深导致弹性凸齿与内齿接触不良，在卡环中部设置了横挡以对圆环进行限位；横挡上设置轴头，轴头插置在左侧板上的轴孔内，一是为了方便 LED 照明模块顺利的转动，二是为了将卡环限制在相应位置，防止其在左侧板上发生滑动。
作为优选，在卡环外周的上下两端对称设有相互平行的滑板，在滑板上设有凸起的滑块，在左侧板内侧面上设有容纳卡环的空腔，在所述空腔的上下两端各设有一条滑轨，所述的滑块卡设在滑轨内。两个平行的滑板与空腔上下两端接触可限制卡环发生周向转动，滑块卡设在滑轨内，防止卡环从空腔内脱落。
为了更好的承受球头，并使球头旋转更加自如，作为优选，在右侧板的上下两棱边上对应开有用以托住球头并使得球头在其内部旋转的弧形槽， LED 照明模块上的球头安放在所述的弧形槽内，导线穿过所述的通孔、孔。
作为优选，所述的 LED 照明模块包括散热装置、导热底板，导热底板的顶面连接散热装置，导热底板的底面上设有印刷电路和多个 LED 灯，圆环与球头分别设置在散热装置的左右两端面上。 LED 照明模块为整体造型，包含了多个 LED 灯，形成一个照明灯管，具有维修、更换方便，聚光效果好的优点。
作为优选，所述的散热装置包括基板，导热底板的顶面连接基板的底面，在基板的顶面并排设置有多个散热翅片，所述的散热翅片是沿基板宽度方向设置，且所述的散热翅片均垂直于基板。
作为优选，散热翅片与基板为一体成型。更利于散热。
作为优选，所述的弹性凸齿与圆环为一体成型，且两者是由橡胶材料制成。由于橡胶质地较软，所以在受力较大的情况下可相对内齿发生滑动。
作为优选，所述的框架定位装置包括设置在框架外侧的框架定位板，框架定位板上端与电源盒、尾盖铰接，在框架定位板上的与框架相接触的端面上由上到下开有多条相互平行的卡槽，所述的卡槽均沿水平方向设置，在框架上与框架定位板相接触的端面上设有至少 1 条与所述卡槽相配合的卡条，卡条卡接在卡槽内。初始状态时，左侧板与框架定位板相接触，卡条卡设在卡槽内，当需调整框架角度时，可将框架定位板翻开，使卡条脱离卡槽，然后将框架旋转一定角度，即右侧板在托板内旋转一定角度，调整好角度好，再将框架定位板放下，使卡条卡接在相应的卡槽内进行框架定位。
作为优选，所述的框架包括左侧板、右侧板及连接左右两侧板的前侧板、后侧板，卡条设置在左侧板上。
作为优选，在框架定位板上由上到下设有 4 条平行的卡槽，在左侧板上端设有 1 个卡条。
 有益效果
本发明的 LED 路灯灯头，主要部分设计成两个左右对称的框架，每个框架内并排设有多个 LED 照明模块，框架的角度及 LED 照明模块的角度均可调节，于是可根据实际的道路情况实时调整框架、 LED 照明模块的角度，保证了理想的路面照明亮度及均匀度，具有较强的实用性。
