Solar streetlights illuminate passers-by. Solar streetlights can sense the arrival of darkness, as well as the dawn and extinction. This is because the solar street lamp has a core controller, so it can control the lighting time. Let me introduce the working principle of solar street lights:

When the solar street lamp leaves the factory, the working time is generally set according to the customer's requirements. The starting and closing time of the solar street lamp is determined by the street lamp controller. Most of the controllers are installed inside the light door, while most of the lithium battery storage and control integrated machines produced by our company are installed at the bottom of the solar panel. Controller adjustment is divided into manual adjustment and remote control adjustment. The external adjustment button can be adjusted manually. However, most of the current markets are remote control adjustment. This type of controller needs to be equipped with a remote control to adjust the working time. How to adjust the time of the solar street lamp also depends on the type of controller used.

1. The charging circuit adopts a dual MOS series control circuit, which can reduce the voltage loss of the circuit by nearly half compared with the use of diodes. The use of PWM energy-saving control greatly increases the power consumption.

2. The load mode adopts pure light control. When the light is dark, the light sensor system will automatically light up. The startup time is intelligently controlled by microprocessor and special control algorithm.

3. Scientific battery management method. When over discharge occurs, the battery voltage will promote charging. After maintenance and compensation, it can be used normally. Direct charging and floating charging are used to connect rechargeable batteries. At the same time, it has a high-precision temperature compensation function, which can control the charge more accurately.

4. All restrictions of all industrial chips and closed components can operate normally in cold, high temperature and humid environments. At the same time, the use of crystal time control can make the time control more accurate.

The above points are the introduction of solar street lamp timing.
