摘　　要：针对目前教室照明系统(DC-DC变换器驱动不同功率的LED灯组)易产生电磁干扰,影响其他电器设备工作及学生身心健康等问题,提出一种基于锯齿波电源且结构简单的低辐射教室照明系统,该系统由主机和分机组成.实验表明,该系统能够实现多地、分区控制教室内的N个LED灯,并能够达到有效节能和降低电磁辐射的目的.因此,该系统在教室照明方面有望得到良好应用.Aiming at the current classroom lighting system(DC-DC converter drives LED lights with different powers)prone to electromagnetic interference,which affects the work of other electrical equipment and the physical and mental health of students,a low-radiation classroom based on sawtooth power supply and simple structure is proposed.Illumination system,the system is composed of host and extension.Experiments have shown that the system can control N LED lights in a classroom in multiple locations and partitions,and can achieve the purpose of effective energy saving and reduction of electromagnetic radiation.Therefore,the system is expected to be well applied in classroom lighting.
