While aging tests may seem simple, the effectiveness lies in the execution. Here’s how we carry out aging tests in real production and pre-shipment stages.
Aging racks or conveyor lines
Adjustable AC power supply (for voltage fluctuation simulation)
Ambient temperature control (optional)
Time tracking and monitoring system
1: Mount the LED lamps securely on the aging rack.
2: Power them on under rated voltage. Common test durations:
Table/Floor Lamps: ≥ 2 hours
Ceiling/Downlights: ≥ 4 hours
3: Observe during operation:
Is brightness stable?
Any flickering, dead LEDs, or color shift?
Abnormal heat, noise, or odor?
4: Recheck the lamps after aging to ensure no deformation or functional faults.
Common Issues & Fixes
| Issue | Possible Cause | Suggested Action |
|---|---|---|
| Flickering | Poor driver quality | Replace with better drivers |
| Partial outage | Faulty soldering/LEDs | Rework or replace LED beads |
| Odor/discoloration | Inadequate heat design | Improve thermal structure |
