LED reliability testing includes four aspects: 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
&Nbsp&Nbsp; LED reliability testing environment testing methods:
&Nbsp&Nbsp; 1、 Normal temperature and pressure impact test:
&Nbsp; Testing method:
&Nbsp; 1. Place 5 LED lamps in an environment with a room temperature of 25 ℃
&Nbsp; 2. Turn on the power supply and light up the LED lamp according to its rated input voltage
&Nbsp; 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
&Nbsp&Nbsp; 2、 Constant damp heat test:
&Nbsp; Testing method:
&Nbsp; 1. Place 5 LED lamps in a constant temperature and humidity box with a relative humidity of 95% and a temperature of 45 ℃
&Nbsp; 2. Turn on the power supply and light up the LED lamp for 48H according to its rated input voltage
&Nbsp; 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
&Nbsp; Testing requirements:
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
