Abstract
The invention provides a light sensing road lamp which comprises a lamp pole, a lamp cover, an LED light source module and a controller. A photosensitive sensing device is arranged above the lamp cover and is in communication with the controller. The photosensitive sensing device is used for outputting high level and low level according to light intensity. A control chip is arranged in the controller. The photosensitive sensing device is connected with the input end of the control chip. The output end of the control chip is connected with the LED light source module and the power supply chip which is connected into a power supply and is used for controlling current passing the LED light source module. A relay is connected between the control chip and the LED light source module. Triggering signals are transmitted to the controller through the photosensitive sensing device according to ambient brightness, and the fact that the controller turns on or off the LED road lamp according to ambient brightness in good time is achieved. The controller can control the brightness of an LED light source according to PWM signals. A timer achieves the fact that the road lamp is turned on or off at a preset moment, and accordingly the LED road lamp can be controlled from light sensing and timing.
