Description

一种LED发光板
技术领域
本发明涉及一种装饰发光板，尤其是一种LED发光板。
背景技术
现在，使用的发光板一般是铺设在地面、墙壁或天花上，该种发光板均是单面发光，其只提供一个发光的平面，缺乏立体光感，装饰效果不好，且原材料利用率不高。目前，尚未有两面均可发光的发光板出现。
发明内容
本发明目的是提供一种不但原材料利用率高，而且还具有U字形两面光感的LED发光板。
为实现上述目的，本发明采用的技术方案是：一种LED发光板由条形灯座、导光板、线路板和LED灯组成，所述导光板是由透明板和设在透明板表面上的具有反射、折射作用的网状凹凸点组成，在所述灯座上沿纵向开有出光槽，在出光槽两侧设有引光板，所述导光板的一边固定在引光板上，线路板设在灯座内，LED灯固定在线路板上，LED灯与出光槽相对应。
网状凹凸点设置在透明板的两表面上。
导光板的另一边为U字形形状。
在所述导光板上设有多个通孔。
所述导光板在U字形厚度边表面为磨沙面。
所述引光板与灯座一体成型。
所述网状凹凸点由导光油墨点构成。
所述网状凹凸点是磨沙后的凹凸。
本发明采用上述结构后，通过在灯座出光槽上安装导光板，所述导光板是由透明板和设在透明板表面上的具有反射、折射作用的网状凹凸点组成，灯座内的LED灯与出光槽相对应，并在出光槽两侧延伸有引光板，因此通过引光板可使LED灯的光集中向导光板方向投射，再经导光板反射和折射在两侧面射出，形成了两面发光的发光板；通过设置一边为U字形形状的导光板，可形成一种U字形立体光感，由于导光板的一边为U字形形状，一块原材料板可一分为二成为两块导光板，几乎没有损耗，因此原材料利用率高；且导光板通过出光槽两侧的引光板固定，安装牢固；进一步的改进是在导光板U字形厚度边表面为磨沙面，使得导光板边沿的光线更加柔和，给人一种舒适感。本发明广泛适用于道路防护栏、室内墙壁、天花等。
附图说明
下面结合附图和具体实施方式对本发明作进一步详细说明：
图1为本发明立体结构图；
图2为图1的截面图；
图3为图1灯座结构图；
图4为本发明气流通过导光板通孔的示意图。
图中：1灯座，11出光槽，12引光板，2导光板，21透明板，22凹凸点，23通孔，3线路板，4LED灯。
具体实施方式
图1、2和3所示，本发明的LED发光板由条形灯座1、导光板2、线路板3和LED灯4组成，所述导光板2是由透明板21和设在透明板21表面上的具有反射、折射作用的网状凹凸点22组成，所述网状凹凸点22由导光油墨点构成或是是磨沙后的凹凸。在所述灯座1上沿纵向开有出光槽11，在出光槽11两侧设有引光板12，所述导光板2的一边通过螺栓固定在引光板12上，线路板3设在灯座1内，LED灯4固定在线路板3上，LED灯4与出光槽11相对应，导光板2的另一边为U字形形状，当然，导光板的另一连也可以是三角形、梯形、菱形形状等等。在所述导光板2上设有多个通孔23，图4所示，通孔23可使气流从导光板2的一侧通过导光板2的另一侧，使得气流作用在导光板2的作用力大大降低，最终达到减少风阻。同时通孔23可形成一种特殊的光效果。装配时，使LED灯4的灯珠正对着导光板2凸起的U字形，这样可使导光板2的出光面出光均匀，形成一种U字形两面光感，立体光感强，装饰效果好。本发明具体使用时，将灯座1固定在防护栏、墙壁、天花或屋顶上，接通电源用做道路、室内的灯光装饰，使得道路或室内在夜晚更加绚丽多彩，对周围环境起到很好的装饰美化效果。
