Can solar street lights be changed to mains?

Solar street lights are currently the mainstream products in street lighting equipment. They are riding the lighting market by virtue of their two major advantages of environmental protection and energy saving. However, despite their many advantages, many users still question their reliability, and some have even been installed. Areas where solar street lights are eager to replace them, what is causing this? After inquiring, it was found that it was because they had bought inferior products, whether it was a light source, a battery, or a battery panel, all of them were second-rate or third-rate miscellaneous brands. In the course of use, it was either bad or that bad. The maintenance fee for a set of street lights is several hundred yuan. This extra cost puts a certain pressure on villages that are not too wealthy. For the relevant person in charge of street lights, it is in a dilemma. It is so bad. Repairing is equivalent to buying a road 'decoration' for more than two thousand yuan. Repair it, and the annual maintenance cost will cost more than ten thousand yuan. In the face of this problem, some people have put forward some opinions, that is, can solar street lights be installed. Change to use 220v mains? This idea is indeed very valuable, so is this approach feasible? The answer is yes, there is no problem at all. The components of solar street lights are four major parts: battery panels, light sources, batteries, and controllers. All work instructions are completed under the cooperation of these four core hardware, which means that problems in any link will cause solar street lights. The work is paralyzed, and the off-brand hardware is very unstable in current and voltage control. This instability will directly cause damage to the light source. If the quality of the light source is not too bad, it is not difficult to change the solar street light to mains. You only need to disconnect the controller, the battery and the battery board from the light source, or completely remove it (the removable Solar modules are used for indoor photovoltaic lighting). Keep the LED light source and install a constant current source at the junction of the 220v mains and the light source line (determine the power supply model according to the power of the LED lamp beads and the form of series and parallel). After the power supply is installed, the solar street light will completely realize the mains start.
