How to adjust the time of solar street lights

Solar street lights illuminate the bright road for passers-by. They can sense the arrival of darkness and turn them off, and they can also sense the dawn and turn off. This is all because of the time controlled by the core controller. So, how to adjust the time of solar street lights?

When solar street lights leave the factory, the working hours are generally set according to customer requirements; the start and stop times of solar street lights are determined by the controller of the street lights. The controller is mostly arranged on the inside of the cabin door. Controller adjustment is divided into manual adjustment and remote control adjustment. External adjustment buttons can be adjusted manually. However, most of the current market is adjusted by remote control. If this type of controller wants to adjust the working time, it must be equipped with a remote control.

How to adjust the time of solar street lights also depends on the type of controller used.

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

2. The load mode adopts pure light control. The light sensing system will automatically turn on the light when it senses that the light is dark. The light-on time adopts a microprocessor and a special control algorithm to realize intelligent control.

3. Scientific battery management method. When over-discharge occurs, the battery voltage promotes charging. After maintenance and compensation, it can be used normally. Direct charging and float charging are used to connect the rechargeable battery. At the same time, it has high-precision temperature compensation to make the charge more accurate. control.

4. All constraints of all industrial-grade chips and closed components operate normally in cold, high temperature, humidity and other environments. At the same time, the crystal time control is used to make the time control more accurate.
