Ternary LED response lamp

The utility model discloses a ternary LED response lamp, set up light -sensitive element and utilized the higher characteristic of LED frequency, adopt the mode of (10ms) shutoff LED lamp in the twinkling of an eye, make the actual illuminance of environment of light -sensitive element lamp of every short -term test in 30 second when the LED lamp is in low bright state, thereby control circuit is according to the actual illuminance of environment control LED gao liang, hang down brightly and do not work, promptly daytime no matter whether someone LED all at the state of not working, and night someone LED gao liang, unmanned LED is low bright, save the electric energy and make the pedestrian convenient, because of the turn -off time weak point, the LED scintillation can not appear in the vision. 本实用新型公开种三态LED感应灯，设置了光敏元件并利用LED频率较高的特性，采用采用瞬间（10ms）关断LED灯的方式，使光敏元件在LED灯处于低亮状态时每隔30秒钟快速检测次灯的环境实际照度，从而控制电路根据环境实际照度控制LED高亮、低亮和不亮，即在白天无论是否有人LED均处于不亮状态，而夜晚有人LED高亮、无人LED低亮，节省电能且使行人方便，因关断时间短，视觉并不会出现LED闪烁现象。
