Radiation source: UVA340 (0.68W/m2) ultraviolet fluorescent lamp or UVB313 (0.6W/m2) ultraviolet fluorescent lamp
Although ultraviolet light (UV) only accounts for 5% of sunlight, it is the main lighting factor causing a decrease in outdoor durability. This is because the photochemical reaction of sunlight increases as the wavelength decreases. Therefore, when simulating the destructive effects of sunlight on the physical properties of materials, it is not necessary to reproduce the entire spectrum of sunlight. In some cases, it is only necessary to simulate short wave UV light.
The reason for using UV lamps is that they are more stable than other lamps and can better reproduce test results. Using fluorescent ultraviolet lamps to simulate the effects of light on physical properties, such as decreased brightness, fading, peeling, etc., is a good method. Most ultraviolet fluorescent tubes produce ultraviolet light, rather than visible and infrared light.

UV lamp aging testing machineStructural features
Selection of UVA-340 simulated sunlight ultraviolet rays
UVA-340 can simulate the critical short wave wavelength range of sunlight spectrum, which is the spectrum with a wavelength range of 295 to 360nm. UVA-340 only produces spectra of UV wavelengths that can be found in sunlight.
UVB-313 is used for large-scale acceleration testing
UVB-313 can provide test results quickly. The short wavelength UV they use is stronger than the UV light waves typically found on the Earth's surface. Although these UV lights, which are much shorter than natural wavelengths, can greatly accelerate experiments
Exposure method: Steam condensation mechanism
After the specified irradiation time, the surface of the sample enters a simulated non irradiated state at night. At this time, the surface of the sample is still heated by a saturated mixture of hot air and water vapor in the exposure chamber, while the back of the sample continues to be cooled by the surrounding air, forming a condensation state on the surface of the sample.
UV irradiation sensor (optional)
The UV aging test chamber is equipped with a UV irradiation sensor. It is a high-precision photometric control system that allows users to select the desired illuminance. Continuous monitoring of light intensity is possible. And fully automated precise maintenance. It can make timely corrections to the light energy caused by lamp aging or any other changes by adjusting the energy of the lamp tube.
