Abstract

本实用新型在现有灯泡的结构上增加了一组钨丝,成为双组三接点钨丝灯泡,从而提高了灯泡的使用寿命。
一种使用于照明的双组三接点钨丝灯泡,在于灯泡内装有两组钨丝,通过三根导线引出,使用该灯泡的灯头上均匀地互成90°分布着四个卡槽,当一组钨丝熔断后,将灯泡旋转90°,又可启用另一组钨丝,从而提高了灯泡的使用寿命。

Description

本实用新型属于家用电器。
一般照明灯泡都是一组钨丝,当钨丝熔断后,灯泡便不能再用,灯泡玻璃壳的利用率很低。
本实用新型的要点在于在原有一组钨丝(1)的基础上又增加一组钨丝(2),钨丝通过导线(3)连接点(4)与灯头的连接点(5)连通。当一组钨丝烧熔后,将灯泡旋转90°,便可启用另一组钨丝,在原有灯泡的使用寿命上延长了一倍。
一般照明灯泡的灯头都只有两个卡槽。
本实用新型的要点在于灯头上有四个卡槽(6),互成90°均匀分布。
当双组三接点钨丝灯泡中的一组钨丝熔断后,只需将灯泡旋转90°,便可启用该灯泡的另一组钨丝。

Claims (3)

1、一种用于照明的双组三接点钨丝灯泡,其特征在于灯泡内装有两组可轮换启用的钨丝。
2、按照权利要求1所述的双组三接点钨丝灯泡,其特征在于灯泡内的双组钨丝分别连接在三个引线支点上,其中一个支点由双组钨丝共用。
3、一种用于照明的双组三接点钨丝灯泡的灯头,其特征在于灯卡上互成90°均匀分布着四个卡槽。
