The temperature cycling test:
Test objects: LED lamps (lamps with LED Driver, finished products).
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.
A: After temperature cycling, LED lamps can not leakage, power off and other electrical anomalies.
