实用新型内容
本实用新型所要解决的技术问题在于提供一种光线柔和、不刺眼的LED灯。
本实用新型是这样实现的，一种高亮度LED灯，包括一PCB板以及若干设于所述PCB板上的LED，所述LED设于一导光体内，或设于所述导光体的侧壁上。
具体地，所述导光体为实心或空心的圆柱形或多棱柱形构件。
进一步地，所述导光体的侧壁设有热压或注塑成型的点状或条状的凹坑或凸起，所述凹坑或凸起由上至下密度渐增排列成阵列状。
更进一步地，所述导光体底部设有磨砂结构。
或者，所述导光体底部底部设有一反射板。
进一步地，所述PCB板与一可将交流电转换成低压直流电的转换器连接，所述转换器上设有一电源接头。
进一步地，所述PCB板、LED和导光体设于一透明外罩内。
本实用新型通过将LED设于导光体的内部或侧壁上，导光体可以将LED的点光源变成体光源，发出的光线变得均匀、柔和、不刺眼。

具体实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
如图2～图5所示，本实用新型实施例提供的一种高亮度LED灯，包括一PCB板1以及若干设于所述PCB板1上的LED 2，所述LED 2设于一导光体3内，所述导光体3可采用透明材料制成，如PMMA等材料。本实用新型通过将LED 2设于导光体3的内部或侧壁上，导光体3可以将LED 2的点光源变成体光源，发出的光线变得均匀、柔和、不刺眼。
具体地，所述导光体3的形状可以为实心或空心的圆柱形或多棱柱形构件，例如，图2所示为实心的圆柱形的导光体3，图6所示为空心的圆筒状的导光体3，图7所示为实心的三棱柱形状的导光体3，当然，导光体3还可以有其他形状。
进一步地，所述导光体3的侧壁设有热压或注塑成型的点状或条状的凹坑或凸起，所述凹坑或凸起由上至下密度渐增排列成阵列状。具体地，所述凹坑或凸起可以是图2所示的球形，或者图3所示的弧形，或者图4所示的倾斜设置的线形，或者图5所示的网格结构，当然还可以为其他形状。通过在导光体3的侧壁设置以上这些形状的凹坑或凸起，可以很好地反射LED 2的光线，使光线向各个方向照射，发出的光线变得均匀、柔和、照明范围广；而之所以将凹坑或凸起由上至下密度渐增地排列，是因为LED 2的光线的密度沿着导光体3从上之下逐渐增加，因此，凹坑或凸起可以反射更多的光线。
另外，如图2～图5所示，所述导光体3下方设有一反射板4，所述反射板4可以对照射到其表面的LED 2的光线进行反射，以提高导光体3的体光源的光线的均匀度。或者，也可以在所述导光体3底部设置磨砂结构，(图中未示出)，这样，导光体3的底部透光但不透视，可以产生朦胧的雾状效果，避免了现有的LED 2的点光源发出的光线眩目、刺眼的现象。
进一步地，如图2～图5所示，所述PCB板1还与一可将交流电转换成低压直流电的转换器5连接，所述转换器5上设有一电源接头6，所述电源接头6既可以是带螺纹的接头(如图2～图5所示)，也可以是卡口结构(如图6～图8所示)，以满足不同的安装场合。
更进一步地，如图6～图8所示，所述PCB板1、LED 2和导光体3还可以设于一透明外罩7内，所述透明外罩7不但起到保护内部器件的作用，还可以起到防尘的作用；而将透明外罩7做成不同的外形，如圆球形(如图6、图7所示)、椭圆球形(如图8所示)或其他形状，可以起到美化、点缀周围环境的作用。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
