我厂是生产TDI的大型化工厂,照明用电是相当可观的,由于手动控制照明较频繁,无形中就增加了很多工作量,天长日久,工作难免疏忽,白天总有亮灯的现象,这样造成很大的能源浪费。本文介绍一种利用一个光控器控制多路照明的电路,即当环境光线为设定的亮度时,各路照明就会自动接通或断开。即天亮断开照明,天黑接通照明,线路简单,性能稳定,每月可节电15％左右,具有明显的经济效益。 1.工作原理 新颖的多回路光电自动控制照明电路(见附图)工作过程如下: 1)首先将三位开关打开自动位置,光控器GK在环境光线暗或亮时,光控
I plant is the production of large-scale chemical plant TDI, lighting electricity is considerable, due to more frequent manual control lighting, virtually increase the workload a lot, over time, work is inevitable negligence, there is always the phenomenon of lighting during the day, resulting in Great energy waste. This article describes a circuit using a light controller to control multiple lighting, that is, when the ambient light is set brightness, the lighting will automatically turn on or off. That is, the lighting is off, the lighting is on when the sky is dark, the circuit is simple, the performance is stable, and the energy saving is about 15% per month, which has obvious economic benefits. 1. Working principle Novel multi-loop photoelectric automatic control lighting circuit (see photo) The working process is as follows: 1) First, the three-position switch to open the automatic position, light controller GK in the dark or bright ambient light, light control
