Abstract

一种节电灯头,其火线、拉线开关、二极管、灯泡、零线顺序连接,还包括与二极管并联的灯头开关。当不需要强光时,可按灯头开关,可省电一半以上,在电压升高时,按下灯头开关,可降压,烧不断灯丝,本灯头采用二极管元件,结构简单。

Description

节电灯头
技术领域:
本实用新型涉及一种节电灯头。
背景技术:
目前公知的白炽灯照明,由火线、拉线开关、灯泡零线,拉线开关控制灯泡亮灭,但在电压升高时,经常烧断灯丝,给用户造成损失。
发明内容:
为了克服现有电灯不能降压,电压升高烧断灯丝的不足,本实用新型提供一种节电灯头,该灯头不仅能够正常照明,而且能方便降压,烧不断灯丝,省电省灯泡。
本实用新型解决其技术问题所采用的技术方案是:一种节电灯头,其火线、拉线开关、二极管、灯泡、零线顺序连接,还包括与二极管并联的灯头开关。
当不需要强光时,可按灯头开关,可省电一半以上,在电压升高时,按下灯头开关,可降压,烧不断灯丝,本灯头采用二极管元件,结构简单。
附图说明:
图1为本实用新型电路原理图;
图2为本实用新型内部结构图;
图3为本实用新型外形主视图。
图中:1:火线;2:拉线开关;3:二极管;4:灯头开关;5:灯泡;6:零线;7、8:灯头接线柱;9:活动开关;10:灯头开关11:灯头
具体实施方式:
如图1所示,电流从火线1到拉线开关2,经过灯头开关4、灯泡5到零线6,这时灯是全波亮度。
当灯头开关断开,电流从火线1到拉线开关2,经二极管3、灯泡5到零线,灯亮是半波,降压省电,烧不断灯丝。
二极管正极安装在接线柱7上,二极管负极安装在活动开关上,活动开关与接线柱7相接是全波,断开是半波。
