Abstract

本实用新型涉及一种灯具,具体是一种以LED为光源的广告牌布光灯。该广告牌布光灯包括有一个布光底板,在布光底板上设置有多个平行的反射槽,反射槽的截面形状为抛物线形,每一条反射槽的底部间隔地设置有多个LED光源。本实用新型广告牌布光灯采用LED作为光源,并通过反射槽的反射表面精确控制投射方向,使得整个灯具光线的方向性大大提高,光照可以集中投射到所需的范围内,减少了散失,节约了能耗。

Description

广告牌布光灯
技术领域
本实用新型涉及一种灯具,具体是一种以LED为光源的广告牌布光灯。
背景技术
广告牌布光灯一般是安置在大面积广告牌的前下方,使用过程中灯光从广告牌前下方投射到广告牌表面。普通的广告牌布光灯一般采用传统光源,其耗电量大、光线的方向性差,广告牌顶部以上会有大量光线散失,为保证广告牌顶部附近有足够的亮度,需要将增大灯具的功率,从而进一步增加了耗电。
发明内容
本实用新型所要解决的技术问题是,提供一种能耗小、光线方向性好、光照均匀的广告牌布光灯。
本实用新型的广告牌布光灯包括有一个布光底板,在布光底板上设置有多个平行的反射槽,反射槽的截面形状为抛物线形,每一条反射槽的底部间隔地设置有多个LED光源。
本实用新型广告牌布光灯采用LED作为光源,并通过反射槽的反射表面精确控制投射方向,使得整个灯具光线的方向性大大提高,光照可以集中投射到所需的范围内,减少了散失,节约了能耗。
附图说明
图1是本实用新型的截面结构示意图;
图2是本实用新型的平面结构示意图。
具体实施方式
如图所示,广告牌布光灯包括有一个布光底板1,在布光底板上设置有多个平行的反射槽2,反射槽的截面形状为抛物线形(如图1所示),每一条反射槽的底部间隔地设置有多个LED光源3。通过控制反射槽内表面抛物线形的曲率,可以改变反射后光线的射出角度,上述布光底板上平行排布的反射槽中,离中心较近的反射槽的射出角度要小于离中心较远的反射槽的射出角度,这样可以使得光线的分布更加均匀。

Claims (2)

1、一种广告牌布光灯,其特征是:它包括有一个布光底板(1),在布光底板上设置有多个平行的反射槽(2),反射槽的截面形状为抛物线形,每一条反射槽的底部间隔地设置有多个LED光源(3)。
2、根据权利要求1所述的广告牌布光灯,其特征是:布光底板上平行排布的反射槽中,离中心较近的反射槽的射出角度要小于离中心较远的反射槽的射出角度。
