[LED bead broken how to do] LED bead repair _LED bead broken how to do

When we use LED beads, the driving current should not exceed the maximum current, it is better not to exceed 20 mA, it is recommended between 10-20 mA; each LED will have different VF value, so in the actual circuit application, it is best to design similar VF value lamp series on a circuit, easy to match different resistance, for the purpose of cross flow; pay attention to the LED polarity is not connected to the wrong, in general, the lamp foot slightly longer one end is positive pole, slightly shorter is negative electrode, if two lamp foot as long, to carefully identify mark.

1, if the LED power supply is damaged, to buy the voltage, current and other same parameters of the power supply, replace it.

2. If the LED beads are more damaged more, and the damaged LED patch lights are concentrated in the same area, the damaged section can be cut off and re-welded.

3, if you have a certain basic knowledge of electronics, to buy the same model of LED lights, carrying a flipping iron, welding can be. But then again, there are a lot of LED patch lamp components on each LED lamp bar, broken one or two, which have no effect on the brightness.

About LED bead broken how to do this problem, we have to do according to what the corresponding measures, whether LED bead damage or drive power damage, for the sake of safety, suggest to find professionals to repair, in use should not only consider the LED itself to the heat of the lamp, but also consider the surrounding environment temperature impact on the photoelectric performance of the lamp.
