Test apparatus and method of accelerated photo-degradation using plasma light source |
摘要 |
Disclosed is a test apparatus of accelerated photo-degradation measuring a degradation caused by photo-degradation in a material or a product by light containing UV light and visible light that simulate the solar light-inducing degradation. The apparatus includes a light irradiating unit configured to irradiate light using at least one electrodeless plasma lamp; a light condensing unit configured to collect light emitted from the light irradiating unit and irradiate the light uniformly into the surface of the specimen for the material or the product; and a specimen holder configured to fix the specimen, and the specimen holder being fixed at a predetermined position or rotated. Further, the at least one electrodeless plasma lamp generates light having a light power spectrum similar to a solar light in a region of UV light and short-wavelength visible light corresponding to a range of about 300-500 nm. |
