本发明的实施方式
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可釆用透明材料制成， 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。
[18] 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。
[19] 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。
[20] 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。
[21] 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。
