LED lamps are used in every city, but how can manufacturers ensure that the LED lamps produced by enterprises are applicable in every city in China? This requires testing lighting fixtures: LED reliability testing, which includes mechanical testing, life testing, destructive testing, and environmental testing. Today, we will focus on analyzing the specific steps and requirements of LED reliability testing environment testing? LED reliability testing environment testing method:
1. Room temperature and atmospheric pressure impact test: Test method: 1. Place 5 LED lamps in an environment with a room temperature of 25 ℃; 2. Turn on the power supply and light up the LED lamp according to its rated input voltage; 3. Control the lamp through a relay to conduct an impact test at room temperature and pressure. The test settings are: turn on the lamp for 30 seconds, turn off the lamp for 30 seconds, and cycle 10000 times 2. Constant Humidity and Heat Test: Test Method: 1. Place 5 LED lamps in a constant temperature and humidity box with a relative humidity of 95% and a temperature of 45 ℃; 2. Turn on the power supply and light up the LED lamp for 48H according to its rated input voltage; 3. After taking out the sample, wipe the surface water droplets dry and place them at normal atmospheric pressure and room temperature for 2 hours before inspection. 3、 Low temperature, low pressure, and impact testing methods: 1. Place 5 LED lamps in an environment of -15 ℃; 2. Adjust the input voltage of LED lamps to 0.9 times the low rated input voltage through a voltage regulator; 3. Connect the power supply, turn on the light for 24 hours, and observe if there are any abnormal phenomena such as damage or material deformation caused by heat on the lamp; 4. After the lighting test, the lamp is controlled by a relay to conduct an impact test in this environment. The test settings are: lighting for 20 seconds, turning off for 20 seconds, and cycling for 100 times Test requirements: A. After undergoing low-temperature and low-pressure testing, the lamp should not exhibit abnormal phenomena such as surface peeling, discoloration, cracking, or material deformation; B. After the impact test, the lamp should not experience electrical abnormalities such as leakage or failure to light up. The editor only listed three aspects of LED reliability testing environment testing for everyone. LED lamps must be able to meet and adapt to the environmental conditions of different cities. If the service life of LED lamps is shortened in high or low temperature environments, manufacturers of such LED lamps need to research and innovate. Otherwise, with the development of LED lamps, such LED lamps are destined to be eliminated from the market. LED reliability testing environment testing and life testing are essential for sold lamps. The lamp market effectively avoids the entry of low-quality LED lamps into the market through LED reliability testing
