Can solar street lights be converted into city electricity?

Solar street lights are now the mainstream products in street lighting devices. With its two major advantages of environmental protection and energy saving, Mercedes-Benz lighting stores have many advantages, but there are still many users who question their reliability, and some are even installed. The areas where solar street lights are installed are eager to replace them. What is the reason for this? After inquiring, it was found that it was because they had bought defective products, whether it was a light source or a battery or a battery panel, all of them were second-rate or third-rate miscellaneous brands. In the process of use, it was either bad or bad. One year later The maintenance fee for a set of street lights alone costs hundreds of yuan. This rated cost is stressful for villages that are not too rich, and for the relevant person in charge of street lights, it is even more difficult to overcome. It is so bad. If you don’t repair it, it’s equivalent to spending more than two thousand yuan to buy the “decoration” of the road. If you repair it, the maintenance cost will cost tens of thousands yuan a year. Facing this problem, some people have put forward some ideas, that is, can solar energy be used. The street lights are changed to use 220v city power? 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 operation instructions are completed under the cooperation of these four central hardware, which means that problems in any link will cause solar street lights. The operation is paralyzed, and the off-brand hardware is very unstable in the control of current and voltage. 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, battery and battery board from the light source, or remove it completely (the one that can be removed can be removed. Solar modules are used for indoor photovoltaic lighting). Save the LED light source, install a drive 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 serial-parallel method), and the solar street light will completely complete the mains power after the power supply is installed.
