Test objects: LED lamps (lamps with LED Driver, finished products).
1) Put 5pcs LED lamps in a oven with temperature of 60℃;
2) Transfer input voltage to 1.1 times of LED light rated voltage by transformer.
3) Power on for 24 hours, and observe whether there is damage to the lamp, thermal deformation of materials and other anomalies;
4) After the light on testing let’s go to the impact test, through the relay controller to control the LED lamp in this environment, the steps is: light on 20 seconds, light off 20 seconds, 100 times cycles.
A: After high temperature and pressure testing, LED lighting surface can not be stripping, discoloration, cracking, deformation and other anomalies;
B: After impact test, LED lamps can not leakage, power off and other electrical anomalies.
