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。
