Abstract

本实用新型公开了一种不用灯罩的多面体定向节能灯泡,它适合于各种定向式照明,如吊灯、台灯、壁灯等,它能将电灯炮发出的光进行充分利用,减少散失,以节约电能。它将电灯泡壁做成多面体形,在不需光线透过的面上涂有反射光的涂层。

Description

本实用新型涉及一种不用灯泡的多面体定向节能灯泡。
普通的照明灯泡由灯头、灯丝、灯泡壁组成。灯泡壁大都是梨形或蘑菇形,它们向四面发射光。人们为了增加照明亮度,一般都是借助反光灯罩进行定向照明。但是仍有许多光能散失。市场上有一种定向投光灯,它的灯泡壁一侧涂有反光层,但是因它的灯泡壁是抛物面,只能起聚光作用,不适合日常照明。
本实用新型的目的是要提供一种改进的局部涂有反光层的多面体形灯泡壁,它能将灯泡发出的光进行充分利用,以减少散失节约电能。
本实用新型灯泡壁做成多面体形,在不需光线透过的面上涂有反光层(铝或水银)在需要光线透过的面保持透明,进行定向照明。
1    以下结合附图作说明:
图(1)是个多面体形向前方照明的灯泡。它由灯头、灯丝、灯泡壁组成,下半部玻璃上有反光层,上半部玻璃透明,它适合吊灯等。图(2)是向侧边照明的灯泡,右边有反光涂层,左边透明,适合壁灯等。图(3)是向侧下照明的灯泡,侧上半部有反光层,侧下透明,适合台灯等。
