General factory, school, street lights, navigation lights on the island. During the day, the duty officer turns off the lights and turns on the lights in the dark. It often causes the switch to be turned off or turned off in time. This will not only waste power, but also affect work.
Based on the relevant information in various aspects, and based on the previous experience of our factory, our factory has restructured a street lamp automatic switch with more practical value. The switch is not affected by the weather season, its function is reliable, its sensitivity is high, and it is sold well all over the world and is very popular among users.
The sensor switch (sound control switch, human body sensor) is equipped with a photosensitive system, that is, it will not light during the day!
It will only be activated at night or when the sky is dark. If there is sound during the day, it will not be a smart switch, it will waste electricity!
Therefore, you can install the switch during the day and experiment at night. Or experiment in a dark place!
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.
Buyer must see:
Do not install with power on, just cut off the power and then connect.
Applicable to 160V-250V voltage. Negative adopts integrated sound and light control delay switch. Through light control, the switch is disconnected and self-locked during the day. There is no light or dark place. With the sound of footsteps or clap, you can start the circuit and delay for 30 seconds Left and right close automatically. Suitable for toilets, corridors, warehouses, stairs and other occasions. Or it can be installed in the doorway or near the windows and doors to effectively deter malicious theft. When entering the sensing range, the light bulb of the load will start automatically. It will stop automatically after the delay. Realize smart home.
