LED Temperature and Humidity Test Chamber Test Method
Target: LED lamps (including finished lamps with LED Driver)
Test Steps:
1）Place 5 LED lamps in a constant temperature and humidity box, with the temperature set at 45 degrees and the humidity set at 95%;
2）Switch on the power for 48 hours according to the rated input voltage of LED lamps (there is a 50mm test hole on the side of the box, through which the external power can be connected)
3）48 hours later, take out the sample, wipe off the water droplets on the surface, and put it under normal atmospheric pressure and normal temperature for 2 hours to check whether the lamp is damaged
Test Requirements:
1. Appearance free from rust, crack or other mechanical damage;
2. Lamps and lanterns shall not be electric leakage, lighting does not work, and other electrical anomalies.
