Description

说明书
Title of Invention:一种超薄 LED面板灯 技术领域
技术领域
[1] 本发明属于 LED照明装置领域， 尤其涉及一种超薄 LED面板灯。
背景技术
背景技术
[2] 目前， LED光源作为一种绿色光源， 与传统光源相比， 有着高纯度、 寿命长、 环保节能等无可比拟的优势， 如今已广泛应用于各种指示、 显示、 装饰、 背光 源、 普通照明和城市夜景等领域。
[3] 现有的 LED面板灯， LED发光体一般为沿管体轴向方向排布， 光源为直下式，
LED发光体之出光中心朝向出光面， 由于受 LED发光体自身发光角度的限制， 往 往造成 LED发光体周围很亮， 无法使发出的光线均匀柔和； 另一方面发出的光线 带有眩光， 不符合人们的视觉要求； 另外， 这种直下式的 LED灯比较厚， 无法满 足人们对超薄化的要求。
对发明的公开
技术问题
[4] 本发明所要解决的技术问题在于提供一种光线柔和、 均匀、 不刺眼的超薄 LED 面板灯。
技术解决方案
[5] 本发明是这样实现的， 一种超薄 LED面板灯， 包括一外壳， 所述外壳内设有一 导光板， 所述导光板下表面加工有网纹结构， 所述导光板下方设有一反射板， 所述导光板两侧设有若干 LED， 所述 LED分别固设于所述导光板两侧的 PCB板上 有益效果
[6] 与现有的直下式 LED面板灯相比， 本发明通过将 LED设于导光板的两侧， 在保 证照明效果的前提下， 显著降低了 LED面板灯的厚度， 实现了 LED面板灯超薄化 ， 便于人们安装和使用， 扩大了其应用领域。
附图说明
[7] 图 1是本发明实施例提供的超薄 LED面板灯的示意图。
本发明的实施方式
[8] 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例
， 对本发明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 以解释本发明， 并不用于限定本发明。
[9] 如图 1所示， 本发明实施例提供的超薄 LED面板灯， 包括一釆用金属或塑胶材 料制成的外壳 1， 所述外壳 1内设有一导光板 2， 所述导光板 2下表面加工有网纹 结构 21， 所述导光板 2下方设有一反射板 3， 所述导光板 2两侧设有若干 LED 4， 所述 LED 4分别固设于所述导光板 2两侧的 PCB板 5上。
[10] 本发明提供的超薄 LED面板灯工作吋， LED 4发出的光线， 从导光板 2两侧进入 ， 然后被导光板 2下表面的网纹结构 21吸收， 再经由导光板 2下方的反射板 3 (或 者导光板 2下表面涂覆的反射物质） 反射， 从而使光线沿着垂直于导光板 2的方 向射出。 与现有的直下式 LED面板灯相比， 本发明通过将 LED设于导光板 2的两 侧， 在保证照明效果的前提下， 显著降低了 LED面板灯的厚度， 实现了 LED面板 灯超薄化， 便于人们安装和使用， 扩大了其应用领域。
[11] 进一步地， 所述 PCB板 5及其上的 LED 4设于一反射罩 6内， 所述反射罩 6 固设于所述外壳 1上， 其具有一呈平板状的底盘 （图中未标示） 以及由底盘周 缘倾斜向上延伸而出的反射壁 （图中未标示） ， PCB板 5及 LED4设于底盘上 。 所述 LED 4发出的光线一部分直接照射到导光板 2内， 另一部分光线照射到 反光罩 6的反射壁上， 经反射罩 6的反射壁反射后， 光线再进入导光板 2内， 这样， 减少了 LED 4的光损失， 提高了光线利用率， 增加了导光板 2的照明亮 度。
[12] 更进一步地， 所述导光板 2上方设有一扩散板 7， 经导光板 2发出的光线进入扩 散板 7后， 扩散板 7使发出的光线具有朦胧的雾状效果， 光线柔和、 均匀、 不刺 目艮、 照射面积大。 [13] 另外， 所述扩散板 7上方设有一透光面板 8， 所述透光面板 8—般釆用透明的有 机玻璃制成， 起到防尘、 保护内部元件的作用。
[14] 以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的 精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本发明的保 护范围之内。
