How to detect whether the solar street light lamp head is damaged

Solar street light lamp head is an integral part of the solar system components, and if the lamp head is damaged, no matter how much power it stores, it is useless. So what are the methods to detect whether the solar street light lamp head is damaged? Then let the professional solar street light manufacturer introduce it to you. First of all, we need to clarify that ED lamp holders are usually divided into two types: built-in constant current source and without constant current source. When we are testing, it is best to take different testing methods for different types of lamp heads. The following will introduce how to correctly and efficiently detect whether the two ED lamp heads are damaged. Built-in constant current source ED lamp head: connect the positive and negative poles of the lamp head output directly to the battery output, check whether the lamp head can be lit normally without the controller, if not, remove the built-in constant current source and replace it with another one and try again Try it, or try it directly with the corresponding control constant current integrated machine. If it can light up normally, it means that the original built-in constant current source is broken, otherwise the lamp bead is broken. ED lamp holder without constant current source: The lamp holder without constant current source is divided into 3 series or more than 3 series. Try to replace other good controllers of the same project. If you replace it once, it means that there may be a problem with the original solar street light controller. Otherwise, there is a problem with the light source of the lamp head. Please check whether there is any problem with the lamp head wire. Check whether the lamp bead is damaged. To check the dead lamp beads, you can use the battery to check 3 or 4 strings of lamp beads one by one, and check them one by one.
