Abstract

本实用新型公开了一种可变色光导标志板。本设计以玻璃或有机玻璃作基板,在基板上做出图形凹槽,凹槽处填充散光材料。基板两端面安装红、绿两种颜色的光源。红色光源发光,绿色光源熄灭时,图形显红色。红色光源熄灭,绿色光源发光时,图形显绿色。红绿两种光源同时发光时,图形显黄色。这各标志板美观、醒目、适于制作各种场合的告示牌等。

Description

变色光导标志板
本实用新型提供了一种可以改变发光颜色的光导标志板。
现有光导标志板是在玻璃或有机玻璃上按照字形或图形刻出凹槽,在凹槽中填充散光材料,在标志板端面设置光源,光线沿玻璃或有机玻璃介质传导至凹槽,凹槽中的散光材料对入射光线产生折射,并在四周乱散射,显示出字形或图形。这种光导标志板发光颜色单调,没有变化,因此不容易吸引人们的注意力。
本实用新型的目的是提供一种能改变发光颜色的光导标志板,能更吸引人们的注意力,增强显示效果。
本实用新型是这样实现的:在3~10毫米厚的玻璃或有机玻璃基板上,刻出1~3毫米深的字形或图形凹槽,在凹槽中填充散光材料,在基板的一个端面安装发红色光的红色光源,在另一端面上安装发绿色光的绿色光源,光源一般采用小灯泡或发光二极管;当红色光源发光,绿色光源不发光时,光线经透明基板的光导传输,使光线传至凹槽,凹槽中的散光材料对红光线形成乱散射,而在凹槽中显示出红色的字形;若红色光源不发光,绿色光源发光,绿光经标志板透明基板光导传输至凹槽,凹槽中的散光材料对绿光线形成乱散射,而在凹槽中显示出绿色的字形;若红色光源和绿色光源都发光,两边的光线经标志板透明基板的光导传输都传至凹槽,凹槽中散光材料对红、绿两种色光形成乱散射,而在凹槽中显示出红绿的混合色——黄色的字形。
下面结合附图和具体实施例对本实用新型作进一步详细说明。
附图是实施例的平面图。
图中:1是玻璃或有机玻璃基板,2是发红光的发光二极管,3是装饰条,4是发绿色光的发光二极管,5是字形凹槽及填充的散光材料。
在厚度为10毫米的有机玻璃基板1上,刻出字形凹槽5,附图中为“入口”字样,凹槽5中填充含大量密集气泡的透明树脂漆,并使其迅速固化,在基板上端面按一定间距嵌入发红光的发光二极管2后用装饰条3固定;下端面也按一定间距嵌入发绿光的发光二极管4后,用装饰条3固定。给红、绿两种发光二极管依次通电,可使标志板依次发出红、绿、黄三种颜色的光线。这种标志板的特点是:美观、醒目、节能。

Claims (3)

1、一种光导标志板,包括透明基板和基板端面上的光源,其特征是:在基板上刻有图形或字形的凹槽,凹槽中填充有散光材料。
2、根据权利要求1所述的光导标志板,其特征在于:透明基板上,上端面所用光源与下端面所用光源发出的光线颜色不同。
3、按照权利要求2所述的光导标志板,其特在于:光导标志板有三种发光状态,(1)上端面光源发光,下端面光源不发光,(2)上端面光源不发光,下端面光源发光,(3)上端面光源发光,下端面光源也发光;三种状态标志板所显图形颜色不同。
