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。
背景技术
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步的说明。
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。
