Second, the working principle and structure
The circuit is equipped with a delay circuit, which has the anti-interference ability of preventing accidental lightning or manual flashlight, automobile, and other light illuminating the photoelectric head, and the falling leaves are low to temporarily block the optical power supply.
The street lamp automatic switch is composed of a power-off conversion device, that is, an electric power head integrated block, an electronic component, and an execution relay. During the daytime, the light is increased, the current of the photosensitive element is increased, the relay of the integrated circuit is released, and the street light is not bright. When the darkness reaches a certain level in the evening, the light generated by the photosensitive element is low due to the weakening of the light, and the relay light is bright until the next day. In the morning, the light enhances the integrated trigger to automatically act again, and the street light is off.
