Abstract

本实用新型是一种双灯丝自动转换灯头,该灯头,由灯头外壳盖、电源接线柱、电子电路板、灯丝接点、灯头外壳体、螺口构成,其特征是,在灯头外壳体的头部设有两个电源接线柱,一块电子电路板,在电子电路板上装有六只晶体管、一只可控硅、两只电阻,在灯头外壳体内中部安有两个灯丝接点。其工作原理,由晶体管对双灯丝灯泡的第一组灯丝进行检测,当每一组灯丝熔断后,该信号即传到选择电路,并由可控硅接通第二组灯丝。该灯头具有全自动转换、无触点、寿命长、成本低等特点,实属一种实现双灯丝灯泡灯丝自动转换的好灯头。

Description

双灯丝自动转换灯头
本实用新型涉及一种灯泡灯头,具体地说是一种双灯丝自动转换灯头。
目前,各灯泡上所拧的灯头,都只能与传统式的单灯丝灯泡配套使用。
本实用新型的目的是,研制出一种既能用于单灯丝灯泡,又能与双灯丝灯泡配套使用的双灯丝自动转换灯头。
本实用新型的主要技术内容在于,该双灯丝自动转换灯头,由灯头外壳盖、电源接线柱、电子电路板、灯丝接点、灯头外壳体,螺口构成,其特征是,在灯头外壳体的头部设有两个电源接线柱、一块电子电路板,在电子电路板上装有六只晶体管、一只可控硅、两只电阻,在灯头外壳体内中部安有两个灯丝接点。其工作原理,由晶体管对双灯丝灯泡的第一组灯丝进行检测,当第一组灯丝熔断后,该信号即传到选择电路,并由可控硅接通第二组灯丝。
本实用新型和现有技术相比所具有的先进之处在于,该灯头不但可与双灯丝灯泡配套使用,而且还能用与传统式单丝灯泡,从而克服了现有灯头功能单一等不足之处。
附图说明:
图1为本实用新型正面剖视结构示意图;
图2为本实用新型电路原理图;
图3为本实用新型电子电路板原理方框图;
其中灯头外壳盖1、电源接线柱2、电子电路板3、灯丝接点A4、灯丝接点B5、灯头外壳体6、螺口7。
下面结合附图1——3对本实用新型再作进一步地描述,用塑料或金属制成灯头外壳盖1和灯头外壳体6、在灯头外壳体6的头部,设有电源接线柱2,电子电路板3,在电子电路板3上分别安有六只晶体管、一只可控硅、两只电阻,在灯头外壳体内中部设有灯丝接点A4、灯丝接点B5、灯头外壳內下部设有螺口7,以上便构成本实用新型。
