Why do LED lights get dimmer the more you use them?

First, the cause of LED lamps and lanterns dimming reasons

1. Driver damage: LED lamps and lanterns need to be converted to low DC voltage suitable for lamp beads through the constant current driver power supply. Any failure within the driver, such as capacitor or rectifier damage, may affect the output voltage, resulting in dim lamps.

Solution: Replacing a damaged driver can usually solve the problem.

2. Burnt LED beads: LED fixtures are composed of multiple beads connected in series and parallel, and a single or partial burnt bead will reduce the overall brightness.

Recognition method: the surface of the burnt lamp beads will have obvious black spots.

Solution: Short-circuit the burnt lamp beads or replace the new lamp beads.

3. LED light failure: LED light failure refers to the lamps and lanterns in use for some time, its light intensity gradually reduced phenomenon. This is the natural aging process that all lamps and lanterns go through, but the light decay of LED lamps and lanterns is relatively slow.

Influencing factors: poor quality LEDs, poor heat dissipation, etc. may accelerate the light decay process.
