The purpose of the UV aging test for outdoor lamps is to evaluate their weather resistance and durability to determine their service life and performance performance under long-term exposure to solar radiation and other climatic conditions. The UV aging test can simulate ultraviolet radiation, high temperature, humidity and other climatic factors in the outdoor environment, and accelerate the simulation of the phenomena of material aging, fading, cracking, deformation and the like that may occur during long-term use by continuously exposing lamp samples, so as to predict their life and performance changes in the outdoor environment.
Industry standard
The industry standards that meet the ultraviolet aging test of outdoor lamps mainly include the following:
IEC 62262: This standard specifies the test methods for impact rating and shell integrity of outdoor lamps, including UV radiation aging test.
ISO 4892-3: This standard specifies the methods and procedures for ultraviolet radiation aging tests of plastic materials under laboratory conditions.
GB / T 16422.3: This standard is CHINA's national standard and is used for ultraviolet radiation aging test methods of outdoor lighting fixtures.
Specific applications
Street lamps and street lamps: UV aging tests of outdoor lamps can evaluate their durability and lighting stability to ensure that they are not affected by ultraviolet radiation and climatic conditions in long-term use.
Garden and landscape lamps: These lamps are often exposed to outdoor environments, and their weather resistance and appearance changes can be evaluated through ultraviolet aging tests.
Pool lights: Outdoor pool lamps are exposed to sunlight and water. UV aging tests can help evaluate their waterproof performance and durability.
Test method
To test the aging resistance of outdoor lamps using an ultraviolet aging test box, follow the following steps:
Preparation of lighting samples: Select outdoor lighting samples that meet the test requirements to ensure that their dimensions and characteristics are consistent with the actual lighting used.
Setting test conditions: according to test standards or specific requirements, setting test conditions such as ultraviolet radiation intensity, temperature and humidity.
Placement sample: Place the lamp sample on the sample stage in the UV aging test box to ensure that the sample is exposed to the light source of UV radiation.
Running test: Start the ultraviolet aging test box, and let the sample be continuously exposed to ultraviolet radiation and other test conditions according to the set test conditions.
Observation and evaluation: regularly observe and evaluate the changes of samples, including color changes, surface conditions, material aging, etc., and record and record relevant data.
RESULTS ANALYSIS: The aging resistance and expected life of the luminaire were evaluated based on the sample changes and performance losses observed during the test.
* The test steps and parameter settings should be adjusted and confirmed according to the test standards and actual needs. It is recommended to refer to the applicable standards and the instructions for the use of relevant equipment before conducting the UV aging test to ensure the accuracy and reliability of the test.
