Is the thermal shock test equipment also used in the LED industry? ?

Some friends think that LED does not need to do temperature impact test , then you are wrong, LED actually Zui should do the impact and temperature test, then what kind of temperature impact test does LED do? High temperature and high pressure and its impact test, Low temperature and low pressure and its impact test, normal temperature and pressure and impact test, temperature points are: room temperature 60 ° C, -15 ° C, 25 ° C specific impact test requirements, please refer to the LED lamp to do the temperature test!

High temperature and high pressure and its impact test:

1) Target: LED lamps (finished lamps with LEDDriver)

2) Reference standard: industry experience

3) Test method: 1. Place 5 LED lamps in a room with a room temperature of 60 °C; 2. Adjust the input voltage of the LED lamps to 1.1 times the rated input voltage of the Zui through a voltage regulator; 3. Turn on the power. , lighting 24H, and observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena; 4, after the lighting test, through the relay control lamp in this environment to carry out the impact test, the test is set to: lighting 20s, 20s off, cycle 100 times.

4) Test requirements: A. After the high temperature and high pressure test, the lamp can not have abnormal phenomena such as surface paint stripping, discoloration, cracking, material deformation, etc. B. After the impact test, the lamp can not be electrically anomalous such as leakage or lighting. phenomenon.

Low temperature and low pressure and its impact test:

1) Target: LED lamps (finished lamps with LEDDriver)

2) Reference standard: industry experience

3) Test method: 1. Place 5 LED lamps in a -15 °C environment; 2. Adjust the input voltage of the LED lamps to 0.9 times the rated input voltage of the Zui through the voltage regulator; 3. Turn on the power , lighting 24H, and observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena; 4, after the lighting test, through the relay control lamp in this environment to carry out the impact test, the test is set to: lighting 20s, 20s off, cycle 100 times.

4) Test requirements: A. After the low temperature and low pressure test, the lamp can not be exposed, such as paint stripping, discoloration, cracking, material deformation, etc. B. After the impact test, the lamp can not be electrically anomalous such as leakage or lighting. phenomenon.

Normal temperature and normal pressure impact test:

1) Target: LED lamps (finished lamps with LEDDriver)

Reference standard: industry experience

2) Test method: 1. Place 5 LED lamps in an environment with a room temperature of 25 °C; 2. Turn on the power according to the rated input voltage of the LED lamps; 3. Control the lamps under normal temperature and pressure through relays. Test, test set to: light 30s, turn off 30s, cycle 10,000 times.

3) Test requirements: After the normal temperature and normal pressure impact test, the lamp can not cause electrical anomalies such as electric leakage and lighting.

So what are the tests for the constant temperature and humidity test equipment for the LED industry:

Temperature cycle test:
1) Target: LED lamps (finished lamps with LEDDriver)
2) Reference standard: industry experience
3) Test method:
1, the 5 LED lamps are placed in a test box, the temperature of the test box can adjust the temperature change rate;
2. Turn on the power supply according to the rated input voltage of the LED lamp;
3, the temperature range of the test box is set from -10 ° C to 50 ° C, the temperature shift rate: greater than 1 ° C / min, but less than 5 ° C / min;
4. The test box is kept at 0.5H for high temperature and low temperature, and is circulated 8 times.
4) Test requirements: After the temperature cycle test, the lamp can not be electrically anomalous such as leakage or lighting.

Constant damp heat test:
1) Target: LED lamps (finished lamps with LEDDriver)
2) Reference standard: industry experience
3) Test method:
1, the 5 LED lamps are placed in a constant temperature and humidity chamber, the constant temperature and humidity chamber is set to a relative humidity of 95%, the temperature is 45 ° C;
2, according to the rated input voltage of the LED lamp, the power supply is turned on 48H;
3. After removing the sample, dry the surface water bead and check it after returning to normal atmospheric pressure and normal temperature for 2H.
4) Test requirements:
1, the appearance is free from rust, cracks or other mechanical damage;
2, the lamp can not be electrically anomalous such as leakage, lighting, etc.

Through the above test requirements, we can see that both the thermal shock test equipment and the constant temperature and humidity test equipment have been applied in the LED industry, and the speed of our standard temperature rise and fall can really meet the requirements. So what is the size of the inner box for the test and test equipment for LED? Pro, this depends on the specific size of your fixture, depending on the specific size of your fixture to choose the size of the cabinet! !

Ok, friends who have any questions about the above standards can always be me! !
