Abstract

本实用新型属于灯罩技术领域,公开了一种LED灯用圆形光匀光罩。其主要技术特征为:包括反光碗,在所述的反光碗上罩有由透明材料制成的匀光体,所述的匀光体背面为平面,其前面为中心薄周边厚的曲面,其截面近似于两个对称排列的半弓形。这样,当光线透过匀光体后,发生散射,光线均匀照射,解决了目前LED灯炫目、亮度不均匀的问题。可广泛应用于家庭照明、车间照明、路灯等领域。

Description

LED灯用圆形光匀光罩
技术领域
本实用新型属于灯罩技术领域,尤其涉及一种LED灯用圆形光匀光罩。
背景技术
随着节能要求的提高,LED灯逐渐代替原来的白炽灯,在家庭照明、车间照明、路灯等领域的应用越来越广泛,但是,由于LED灯在一个圆形内亮度高、而在周边领域则光线非常暗,在亮度高的地方会刺眼、炫目,因此难以大范围推广。
实用新型内容
本实用新型要解决的技术问题就是提供一种照度均匀、便于推广LED灯的LED灯用圆形光匀光罩。
为解决上述问题,本实用新型采用的技术方案为:包括反光碗,在所述的反光碗上罩有由透明材料制成的匀光体,所述的匀光体背面为平面,其前面为中心薄周边厚的曲面,其截面近似于两个对称排列的半弓形。
其附加技术特征为:
所述的匀光体为圆形;
在所述的匀光体背面设置有座板;
所述的半弓形弧线的弧度为40±6°。
本实用新型所提供的LED灯用圆形光匀光罩与现有技术相比,具有以下优点:其一,由于包括反光碗,在所述的反光碗上罩有由透明材料制成的匀光体,所述的匀光体背面为平面,其前面为中心薄周边厚的曲面,其截面近似于两个对称排列的半弓形,当光线透过匀光体后,发生散射,光线均匀照射,解决了目前LED灯炫目、亮度不均匀的问题;其二,由于在所述的匀光体背面设置有座板,方便了匀光体的安装;其三,由于所述的半弓形弧线的弧度为40±6°,使得光线照射更加均匀。
附图说明
附图为本实用新型LED灯用圆形光匀光罩的结构示意图。
具体实施方式
下面结合附图对本实用新型LED灯用圆形光匀光罩的结构和使用原理做进一步详细说明。
如附图所示,本实用新型LED灯用圆形光匀光罩包括反光碗1,在反光碗1上罩有由透明材料制成的匀光体2,匀光体2位于反光碗1一面为背面21,与背面21相对的一面为前面22,背面21为平面,前面22为中心薄周边厚的曲面,其截面近似于对称排列的两个半弓形。当光线透过匀光体2后,发生散射,光线均匀照射,解决了目前LED灯炫目、亮度不均匀的问题。
为了便于匀光体2的安装,匀光体2设计为圆形,且在背面21上设置有座板23。
为了使得光线照射更加均匀,匀光体1截面的半弓形弧线31的弧度为40±6°。
该LED灯用圆形光匀光罩不仅仅适用于LED灯,对于其他光源上使用的灯罩,只要结构与上述LED灯用圆形光匀光罩的结构相同,都落入本实用新型保护范围之内。
