Simulated sunlight Ultraviolet light in the sun is a major contributor to the durability of most materials. We use UV lamps to simulate the short-wave ultraviolet portion of sunlight, which produces very little visible or infrared spectral energy. We can choose UV lamps of different wavelengths according to different test requirements, because each lamp has different energy and wavelength in total UV irradiation. Generally, UV lamps can be classified into two types: UVA and UVB. UVB-313 Lamp: UVB-313 The short-wavelength UV light emitted by the lamp is stronger than the sun's ultraviolet rays normally applied to the Earth's surface, which can accelerate the aging of the material to a greater extent. However, the lamp may cause unrealistic damage to certain materials. It is mainly used for quality control and research and development, or for running tests on materials with extremely high weather resistance. UVA-340 lamp: The UVA-340 lamp is excellent for simulating short-wavelength UV light in sunlight, from 365 nm to the sun's cut-off point of 295 nm. UVA-351 Lamp: Simulates sunlight through the window glass, which is most effective for aging the material in the test chamber. (All the above lamps are imported lamps originally from the United States)
