自动节能报警灯利用传感天线完成运动人体对灯自动亮、灭及报警的控制。光线暗淡时,如人在感应范围内走动,灯会自动点亮进入延时状态。在延时时间内,有人继续运动,灯保持不灭,直至人静止不动或退出感应范围,灯再随延时时间结束而熄灭。根据需要,外加小报警盒.灯亮时响,灯灭时停。工作原理如图所示,传感天线 L 时刻接收人体运动信号。当有人运动,V2(C)脚电平上下微动,经 A4、A1两次放大,送至 A2(6)脚,是一电压幅度变化较大 Automatic energy-saving alarm lights use the sensor antenna to complete the movement of the human body automatically light on, off and alarm control. Light dim, such as people moving within the sensing range, the light will automatically light into the delay state. During the delay time, some people continue to exercise, the lights remain immortal, until the person is stationary or out of the sensing range, the lamp then goes out with the delay time. According to the need, plus a small alarm box. Working principle As shown, the sensing antenna L receives the signal of human motion at all times. When someone moves, V2 (C) feet up and down fretting, A4, A1 amplified twice, sent to A2 (6) feet, is a larger voltage amplitude changes
