Abstract

本实用新型涉及一种高对比度室外光栅LED显示屏,其能增强光栅显示屏的对比度,提升显示效果,安装简捷,风阻小。本实用新型包括灯条,相邻灯条之间设置有挡光条,每一灯条的上部或下部开有沟槽,挡光条插入沟槽内。

Description

一种高对比度室外光栅LED显示屏
一、技术领域:
本实用新型涉及一种光栅LED显示屏,尤其是涉及一种高对比度室外光栅LED显示屏。
二、背景技术:
背景技术中,因光栅显示屏具有重量轻、结构薄、安装简捷、风阻小等诸多优点,客户不仅在楼面外使用光栅显示屏,更希望在大型写字楼、商厦及其他临街建筑的楼顶使用。但在楼顶使用时,因该产品为光栅式透光设计,显示屏的对比度低,显示效果不理想。
三、实用新型内容:
本实用新型为了解决上述背景技术中的不足之处,提供一种高对比度室外光栅LED显示屏,其能增强光栅显示屏的对比度,提升显示效果,安装简捷,风阻小。
为实现上述目的,本实用新型采用的技术方案为:
一种高对比度室外光栅LED显示屏,包括灯条,其特征在于:相邻灯条之间设置有档光机构。
上述档光机构为档光条。
上述每一灯条的上部或下部开有沟槽,档光条插入沟槽内。
与现有技术相比,本实用新型具有的优点和效果如下:
本实用新型能增强光栅显示屏的对比度,提升显示效果,且档光条向后倾斜,与相邻灯条之间有一定的缝隙可以降低风阻,同时继续保持光栅显示屏重量轻,结构薄,安装简捷,风阻小的特点,极大的拓宽了光栅显示屏的应用领域。
四、附图说明:
图1为本实用新型的结构示意图;
图2为图1的局部(A部)放大图。
图中,1-灯条,2-档光条。
五、具体实施方式:
本实用新型是一种具有增强对比度机构的室外光栅LED显示屏,因增强对比度机构的形状是条形的,应用在室外光栅LED显示屏结构中实现遮挡光线的目的,称之为档光条,制作材料可采用现有的各种材料.参见图1和图2,包括灯条1,相邻灯条1之间设置有档光条2,每一灯条1的下部开有沟槽,档光条2插入沟槽内,档光条2可以在灯条1的两端分别滑动进灯条1内,这样档光条2能够将光栅屏背面的光线进行遮挡,光栅显示屏具有很好的黑底色,增强光栅显示屏的对比度,提升显示效果.同时档光条2向后倾斜,与相邻灯条1之间有一定的缝隙可以降低风阻,继续保持光栅显示屏重量轻、结构薄、安装简捷、风阻小的特点,极大的拓宽了光栅显示屏的应用领域.当然,沟槽也可开在灯条的上部,也可达到本实用新型的目的.

Claims (3)

1.一种高对比度室外光栅LED显示屏,包括灯条(1),其特征在于:相邻灯条(1)之间设置有档光机构。
2.根据权利要求1所述的一种高对比度室外光栅LED显示屏,其特征在于:档光机构为档光条(2)。
3.根据权利要求2所述的一种高对比度室外光栅LED显示屏,其特征在于:每一灯条(1)的上部或下部开有沟槽,档光条(2)插入沟槽内。
