为了提高节电效果、降低维修费、节约资金,本文提出了对传统声光控制楼道灯的改进,文中给出了各电路原理图及元件参数的选择。当光暗时,电路的拾音器只要检测到有碎发声响就会自动明亮为人照明过一段时间后又自动熄灭,节能节电。 In order to improve energy-saving effect, reduce maintenance costs, save money, this paper presents the improvement of traditional acousto-optic control corridor lights, the paper gives the choice of circuit schematics and component parameters. When the light is dark, the pickup of the circuit will automatically bright as long as it detects the broken sound, and then automatically turns off after a period of lighting, saving energy and electricity.
