学校教室内的照明，采用普通拉线开关或墙壁开关控制的占绝大多数。虽然这种安装方式比较节省资金，但从节约电能角度来讲，这种控制方式确实有改进的必要。通过多次试验，我们设计出了一种针对教室用电的定时光控节能控制装置。1功能简述根据学校教学的特点，可以通过定时装置
School classroom lighting, using ordinary cable switch or wall switch control accounted for the vast majority. Although this installation method saves money, but from the perspective of energy conservation, this control does have the necessary improvements. Through many experiments, we designed a time-controlled energy-saving control device for classroom electricity. 1 Function Description According to the characteristics of school teaching, you can through the timing device
