It should be that the power parameters of the newly replaced lamp beads are different from the original ones.

Why led beads are not durable after replacement
It should be that the other undamaged life is also approaching, so it must be replaced.
Why is the life of led lamp beads not long
The reasons for the short use time of led beads are as follows: various companies (small companies) do not control the quality of the process well; The poorly welded lamp bead conducts electricity to the aluminum substrate (the lamp bead is welded to the aluminum substrate).
The main internal solder joints of LED lamp beads are poor, broken wires, lamp bead defects, excessive power and high temperature burn out, under a high-multiple microscope, the cause of the failure is easy to find out;
As the LED lamp manufacturer in the screening of the packaging plant chip source, chip size, substrate material, substrate process, surface adhesive material, gold wire or alloy wire, etc., to make clear requirements, strict screening of packaging manufacturers.
Can the LED lamp be used for a long time
Led lights, lamp beads are damaged, replace the same specifications, or can be used. Unless a replacement can be used for a long time, the continuous bad will be changed, and it will not be long. Because the number of lamp beads on the led light board, the circuit form, and the power of the lamp beads are closely related to the driver, as long as the lamp bead replacement does not match the original lamp bead, because the driver is unchanged, the life after replacement and maintenance will not be long.
If the lamp bead is used in series, short connecting a lamp bead will cause the voltage and current on the other lamp bead to increase, and the lamp bead will be brighter than before, which will definitely affect the service life of the lamp bead.
