What is the principle of induction street lights

Time:2023-12-20 Views:933


Inductive street lights use infrared sensing modules and PMW control to sense the human body, which can detect the thermal radiation of the human body, thereby increasing the brightness of the lights when someone approaches, and reducing the brightness of the lights when people leave, achieving the effect of energy conservation. It is an intelligent street light.

The induction street light has a single chip control, which controls the brightness by adjusting the duty cycle. The LED beads used are environmentally friendly. The sensing distance of induction street lights can be selected according to the installation interval of solar street lights, even if the distance is far, it can achieve sensitive sensing and meet the requirements of humanization.

2Introduction to the workflow of solar induction street lights

1. Charging with sunlight during the day is ideal for 8-10 hours.

2. At night, the lighting fixtures automatically start the micro light mode. When someone passes by, the infrared sensing device is triggered, and the light automatically turns on the strong light mode. The strong light usually lasts for 30 seconds, and can also be adjusted to continuously connect to the strong light mode when someone is within the sensing range.

3. When a person leaves the sensing range, the light automatically switches to a slightly lit mode, waiting for the next time someone approaches before adjusting the strong light mode.
