Abstract
一种能够根据用户的需要,调节白炽灯度的节电
开关。由双控开关、二极管组成,开关分正常发光挡、
弱光挡、关闭挡等三挡,利用二极管对交流进行半波
整流后对白炽灯供电,从而获得此正常发光节约用电
的弱光。
Description
本实用新型涉及到电源开关方面,特别是能够调节白炽灯亮度的开关。
目前,公知的调光方法有:子母灯调光,二极管调光,电感器有级调光和双向可控硅无级调光。本实用新型是选用二极管安装在现有的双控拉线开关里面,即可获得一个经济便宜、实用的调光节电开关。
本实用新型的目的是这样实现的:如附图所示的拉线开关,(1)为二极管,工作电压应大于400伏,电流大于或等于1安,如选用1N4007。开关实际为双控开关,即双控开关(2)、(3)两动触点之间连接二极管(1),如附图所示,小图为开关的机械接触图。很明显,开关有三种特征:①电灯正常发光,如小图所示那种接触方式,图中(4)为铜片。②电灯亮度变小(弱光),即电流从铜片(2)到二极管(1)到铜片(4)到铜片(5)经白炽灯,由于二极单向导电,所以只有半波交流电通过,所以白炽灯亮度减弱,如小图所示那种接触方式,顺时针方向过一档。③电灯熄灭,如小图所示那种接触方式过两档。所以开关有续提供强光档、弱光档、关闭档。
Claims (1)
