How to replace 12V solar LED street lights with 220V LED street lights

When you see the title "How to replace 12V solar LED street lights with 220V LED street lights", are you surprised? In fact, this is also a solution I provided to a customer in July.

At that time, the customer wanted a 120W solar LED street light with a connection method of 12V, but in July, our company did not have any solar LED street lights with a connection method of 12V. Professionals should know that LEDs work with 12V or 24V DC. In order to suit the use of the majority of existing customers, transformers are generally installed in the lamp body to convert 220V AC into 12V or 24V DC to allow LED lights to work. Therefore, most of the street lights in our company's inventory are connected with 220V AC.

Since we didn't have 12V solar street lights in stock on July 28, the customer said he was in a hurry to try out the samples, so we could only provide them with a solution, which was to go to the hardware store and buy a transformer, which costs about 20 yuan. Any hardware store has it, and it can convert 12V DC into 220V AC, so that they can try it out.

Customers may also ask, the LED input method is 12V/24V, so is it possible to directly break the transformer inside the lamp and use 12V power input directly?

This is definitely not feasible, because the structure of the lamp is complicated, and there are many things involved, which is not convenient to operate in this way. So I tactfully persuaded the customer to adopt the above method.
