Ⅰ. The principle of solar sensor street light
The solar sensor street light uses infrared sensor module and PMW control to sense the human body. As a smart street light, it can detect the heat radiation of the human body, thereby increasing the brightness of the lamp when someone approaches, reducing the brightness of the lamp after the person leaves and achieving the effect of saving energy. The solar sensor street light has a single-chip control, which controls the brightness by adjusting the duty cycle. The lamp beads use environmentally friendly LED lamp beads. The sensing distance of the sensor street light can be selected according to the installation interval of the solar energy street light.

Ⅱ. Introduction to the work process of the solar sensor street light
The solar sensor street light is charged under sunlight during the day, and the ideal state is 8-10 hours of charging. The light will automatically start the dim mode at night, and the infrared sensor will be triggered when someone passes by, and the light will automatically turn on the strong light mode. The strong light usually lasts for 30 seconds. It can also be adjusted to the strong light mode when someone is within the sensing range. When a person leaves the sensing range of the solar energy street light, the light automatically switches to the dim light mode, waiting for the next time someone approaches.

Ⅲ. The advantages of solar powered street lights
1. Energy saving and environmental protection: The main advantage of solar sensor street light is energy saving and environmental protection. Because it is an automatic control product made with infrared technology, when the human body enters the sensing area, the switch will automatically turn on the load. If the human body does not leave and keep moving, the sensor light will continue to be on; after the person leaves, the delay design will automatically turn off the load, which is a good way to achieve "the lamp turns on when the person arrives, and off when he/she leaves", avoiding the waste of energy.

2. Automatic metering: The switch of solar sensor street light has an automatic metering design, and the sensor will be disconnected when the light is strong during the day; and the sensor street light has a contactless electronic switch, which extends the life of the load.

3. Reliable sensing: Solar energy street light uses thyristor circuits with high safety, wide sensing range and sensitive sensing performance.

4.High cost performance: The solar sensor street light adopts all-aluminum lamp panel, which is not easy to be deformed, discolored or damaged with a long service life; and the price of solar street lamps is not expensive for solar energy is used as a source of electric energy.
