Brief introduction to the working principle of solar street lamp controller
Brief description of solar street light controller
The controller is an electronic device placed inside the solar street light to control the turning on and off of the solar LED light, which is equivalent to the central computer of the entire solar street light.
Two control methods:
1. Light control: It mainly senses the strength of the external light through the sensor. When the light reaches a certain degree of darkness, it will automatically turn on the solar street light. When the outside light reaches a certain bright spot, it will turn off the solar street light. As for the control of light and darkness, it can be adjusted manually. Most solar street lights now use this method.
2. Time control: It is mainly to determine the switch of solar street lights by timing. This method was used a lot earlier, but now it is used less. The main reason is that it is inconvenient to use time control even if it is in the same area in different seasons.
The components of the controller:
1. Hardware part: the combination of ordinary circuit board and chip.
2. Software part: make different control software according to different solar street lights.
