What is the reason why the 48w led panel light is not bright

Information

48w led panel light does not light up after a period of time or one line does not light up. So many users have doubts about the materials used in the panel lights. The 48w led panel light manufacturer will explain to you what causes it, but it has nothing to do with the materials we use.

48w led panel light

There are reasons why one or several lines of 48w led panel light do not light up:
1. The circuit design of 48w led panel light is 10 series and 5 parallel, such as whether one or several circuit boards are open;
2. Whether the lamp bead has false welding, false welding or cold welding;
3. The lamp bead itself does not turn on due to open circuit or necrosis;

The reason why the 48w led panel light does not light up as a whole;
1. Whether the connection point of the power input line is loose or disconnected;
2. Whether there is any loose or open circuit between the power output and the circuit board.
3. The drive power supply is broken.

The above is the summary of the reasons why the 48w led panel light does not light up, I hope it will help you.
