Description

一种可聚光的 LED显示屏
技术领域
本实用新型涉一种 LED屏领域， 具体是涉及一种能减少光衰、 有 效聚光， 并达到良好散热效果的显示屏。
體
LED显示屏是一种用发光二极管按顺序排列而制成的新型成像电 子设备。由于其亮度高、寿命长等特点，正被广泛应用于显示领域中。 由于现有的 LED显示屏中光源直接发光并散发出来，在 LED散发热量以 及光线浪费的作用下， 导致 LED 显示屏的光衰减效率较大， 使得 LED 显示屏色调单一、 发光效率低， 使用寿命短， 制造难度高， 所以现有 的 LED显示屏产品的光照强度、散热性以及寿命均不能达到理想状况， 急需改善， 另外， 目前使用的 LED灯光存在光亮度不够的问题也需要 解决。
实用新型内容
针对现有技术中的不足， 本实用新型提供一种可聚光的 LED显示 屏， 通过聚光功能， 能有效的将普通 LED光源发出的光进行聚合， 增 强光亮程度， 也有效增加了 LED显示屏的使用寿命。
为了解决上述技术问题， 本实用新型的技术方案如下：
一种可聚光的 LED显示屏， 包括电路板和 LED灯， 其特征在于， 所述 LED灯被一个半球形的聚光腔包围，聚光腔的内表面涂有反射材 料， 外表面设有散热层， 聚光腔内与电路板连接的位置涂有绝缘隔热 层， 半球形的聚光腔顶端设有一斜向下的出光口。 所述出光口与水平线的夹角为 30 ° 到 60° 之间。
本实用新型的有益效果在于： 本实用新型使 LED发出的光有效聚 合， 减少光衰， 达到增加光强的效果， 并且散热效果好， 增加了 LED 显示屏的使用寿命， 另外， 出光口斜向下的角度有效减少光亮在空气 中的散发， 有利于行人的观看。 设计合理， 制作工艺简单。
附图说明
下面结合附图以及实施例对本实用新型做进一歩的说明。
图 1为本实用新型的结构示意图。
具体实施方式
如图 1所示， 本实用新型提供的 LED显示屏在现有电路板加 LED 灯的基础上增加了聚光结构， 具体的为：
电路板 1上设有若干个 LED灯 2， 没给 LED灯 2都被一个半球体 的聚光腔 4包围， 为了有效聚光， 在聚光腔 4内侧涂有反射材料。 为 了能够有效散热， 在聚光腔 4的球体外侧设有散热层 6， 并且在聚光 腔 4内与电路板 1接触的位置设有绝缘隔热层 3， 这样能有效增加聚 光效果， 减少光衰， 并且增加 LED显示屏的使用寿命。
在半球体的聚光腔 4的顶端设有一开口，在开口上有一斜向下的 出光口 5， 使光线从出光口 5发射出来。 出光口 5斜向下的设计能减 少 LED灯 2发出的光亮在空气中的散发，将更多的光线照射到行人眼 中， 减少了光亮在空气中的浪费。 优选的， 为了达到更好的效果， 出 光口 5与水平线之间的角度控制在 30° 到 60 ° 之间。
以上所述仅是本发明创造的优选实施方式， 应当指出： 对于本技 术领域的普通技术人员来说，在不脱离本发明创造所述原理的前提下， 还可以做出若干改进和润饰，这些改进和润饰也应视为本发明创造的 保护范围。
