摘要
目前大部分学校教室都是用普通开关来控制灯具,控制方式单一,无法适应课间、午休、教学投影等场景。为了更好地节能,以及适应当前教学的需要,设计了一种基于DALI协议的多场景可调的教室照明方案。该方案包含灯具、触摸面板、照度传感器和总线电源等设备。灯具提供照明;总线电源提供信号总线;触摸面板可以开关灯具,调节灯具亮度,调用预置场景;照度传感器可检测课桌面的照度,特定场景下,可以实现课桌面恒照度控制,进一步节能增效,延长灯具寿命。
Currently,most school classrooms use ordinary switches to control lighting fixtures,with a single control method that cannot adapt to scenes such as breaks,lunch breaks,and projections.In order to better save energy and meet the current teaching needs,a multi scene adjustable classroom lighting scheme based on DALI protocol has been designed.In addition to lighting fixtures,this solution has added a touch panel and an illumination sensor.The touch panel can switch on and off the lighting fixtures,adjust the brightness of the lighting fixtures,and call up preset scenes.The illumination sensor can detect the illumination of the classroom desktop.In specific scenarios,it can also achieve constant illuminance on the classroom desktop,further saving efficiency and extending the lifespan of lighting fixtures.
