LED industry testing methods there are many, it is to do a detailed description of several methods commonly used LED industry.
First, high temperature and high pressure and its impact test:
Target: LED lamps (finished lamps with LEDDriver)
Test Methods:
1. Place 5 LED lamps in a room with a room temperature of 60 ° C;
2. Adjust the input voltage of the LED lamp to 1.1 times the maximum rated input voltage through a voltage regulator;
3, turn on the power, light 24H, and observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena;
4. After the lighting test, the impact test is carried out in this environment through the relay control lamp. The test setting is: lighting for 20s, extinguishing for 20s, and cycling for 100 times.
Testing requirements:
A. After the high temperature and high pressure test, the lamp can not be exposed, such as paint stripping, discoloration, cracking and material deformation.
B. After the impact test, the lamp cannot be electrically anomalous such as electric leakage or lighting.
Second, low temperature and low pressure and its impact test:
Target: LED lamps (finished lamps with LEDDriver)
Test Methods:
1, the 5 LED lamps are placed in a -15 ° C environment;
2. Adjust the input voltage of the LED lamp to 0.9 times the minimum rated input voltage through a voltage regulator;
3, turn on the power, light 24H, and observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena;
4. After the lighting test, the impact test is carried out in this environment through the relay control lamp. The test setting is: lighting for 20s, extinguishing for 20s, and cycling for 100 times.
