The temperature cycling test:
Test objects: LED lamps (lamps with LED Driver, finished products).
Test method:
1) Put 5pcs LED lights in high and low temperature chamber, and this chamber can adjust temperature changing rate.
2) Input the rated voltage to the LED lights;
3) Set temperature range from -10℃ to 50℃, temperature speed rate: more than 1℃ / min, but less than 5℃ / min;
4) Keep the LED lamp both 0.5 hours in high and low temperatures, repeated 8 times.
Test requirements:
A: After temperature cycling, LED lamps can not leakage, power off and other electrical anomalies.
