White LED lamp beads are voltage-sensitive devices. In actual work, the current is 20mA as the upper limit, but the current will often increase due to various reasons in use. If no protective measures are taken, this increase The LED lamp beads will be damaged after the current exceeds a certain time and amplitude. The main reasons for the damage of the LED lamp beads are:
① Sudden increase of the power supply voltage.
② The short circuit of a component or printed line or other wire in the circuit forms a local short circuit of the power supply path of the LED lamp beads, which increases the voltage in this place.
③ A certain LED lamp bead is short-circuited due to its own quality damage, and its original voltage drop is transferred to other LED lamp beads.
④ The temperature inside the lamp is too high, which makes the characteristics of the LED lamp bead deteriorate.
⑤ Water has entered the lamp, and the water is conductive.
⑥ The anti-static work was not done well during assembly, so that the inside of the LED lamp bead has been damaged by static electricity. Although the normal voltage and current values are applied, it is very easy to cause damage to the LED lamp beads.
