- 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.
- Abstract:
- 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.
