LED for reliability test method

4 May

With flexible led strip lighting technology in the application of lighting, LED products in the global set off a storm of saving energy and environmental protection green, is now known as the “green light” products. In more and more high energy consumption today, even some have predicted: “in the next 10 years, LED products will be replace incandescent lamp, high-pressure sodium lamp, fluorescent lamp, traditional lighting lamps only products.”

1. Will led lamps placed in a-15 ℃ environment;

Testing method: light testing, through the relay control lamps and lanterns in this environment impact test;

The test set to: 20 s, light lights out 20 s, circular 100 times;

According to the object: led lamps and lanterns (including leddriver finished product lamps) test requirement.

2. Test box in the low or high temperatures keep 0.5 h, circular 8 times;

Test requirement: consult standard: industry experience, switch on the power, light the lamps 24 h, and observe whether have damage, material lamps heated deformation anomaly;

According to the object: led lamps and lanterns (including leddriver finished product lamps),

Test cases of the temperature change of the range from 10 ℃-set to to 50 ℃, the temperature variable speed rate is greater than 1 ℃ / min, but less than 5 ℃ / min.

3. Will led outdoor lighting fixtures package placed in samples of vibration test on the stage;

Lamps and lanterns in low temperature low pressure test after, cannot happen surface take off paint, changing color, material deformation crack, abnormal phenomenon;

According to the object: led lamps and lanterns (including leddriver finished product lamps) led lamps test method,

High temperature and high pressure and its impact test: in the object: led lamps and lanterns (including leddriver finished product lamps) test requirement: consult standard: industry experience.

4. Turn on the power, light the lamps 24 h, and observe whether have damage, material lamps heated deformation anomaly; Consult standard: industry experience

According to the object: led lamps and lanterns (including leddriver finished product lamps),

The samples will drain dry surface of water on the normal atmospheric pressure and under normal temperature, the recovery after 2 h check;

Lamps and lanterns in after high temperature and high pressure testing, not happen surface take off paint, changing color, material deformation crack, abnormal phenomenon;

mini led light bars testing, through the relay control lamps and lanterns in this environment impact test, test set to: 20 s, light lights out 20 s, circular 100 times. Testing method: lamps and lanterns in temperature cycle through test, can’t happen in bright light leakage, such as electrical anomaly.

5. According to the input voltage led lamps rated supply power to light a lamp;

Consult standard: industry experience

According to the input voltage led lamps rated supply power to light a lamp 48 h;

6. Constant damp and hot test: lamps and lanterns in shock after testing, can’t happen in bright light leakage, such as electrical anomaly.

Testing method: according to the input voltage led lamps rated supply power to light a lamp; Through the relay control under the conditions of lamps and lanterns in under impact test,

The test set to: 30 s, turn out the lights light 30 s, circular 10000 times.

Lamps and lanterns in after impact test, can’t happen in bright light leakage, such as electrical anomaly.

7. Through the regulator will led lamps for maximum rated the input voltage of the input voltage of 1.1 times; Will the above method in fluctuation lamps, before and after the left and right sides, three directions in 30 minutes were tested.

Will led lamps placed in a room temperature 25 ℃ for the environment;

The temperature cycling test: through the regulator will led lamps input voltage to a minimum of the input voltage of 0.9 times rated;

8. Will led lamps placed in a constant temperature and humidity box, constant temperature and humidity box set to 95% relative humidity, temperature for 45 ℃;

Testing method: consult standard: industry experience

Lamps and lanterns in under the conditions of impact test after, can’t happen in bright light leakage, such as electrical anomaly.

9. Under the conditions of impact test: will led lamps placed in a room temperature for 60 ℃ room;

The vibration velocity tester vibration is set to 300 r/min, amplitude set to 2.54 cm, start vibration apparatus;

Test method: low pressure and low impact test: will led lamps placed in a test case, the test of temperature can adjust the temperature change rate; According to the object: led lamps and lanterns (including leddriver finished product lamps)

Led lamps vibration test: test requirement: testing method: lamps and lanterns in after vibration test, can’t happen parts fall off, the structure damage, bright light abnormal phenomenon.
