The main structural types of the xenon lamp aging tester are rotary drum type and flat type, namely air-cooled and water-cooled. Rotary drum type xenon lamp aging test machine, which uses a xenon tube installed vertically in the center of the device as a light source, the xenon tube is surrounded by an optical filter, the tube is water cooled; the test sample is mounted on the light source around the center lamp The tube is rotated on the sample holder. It is equipped with one or more air-cooled xenon lamps on the top of the test chamber in a flat-type xenon lamp aging tester. The flat-type optical filter is placed in the lower part of the lamp tube, and a reflection system is installed on the top and side of the test chamber. To enhance the uniformity of the irradiance; the test sample is statically placed on the sample pan below the tube. The structural characteristics of these two types of xenon lamp aging test machines: the structure of the rotating drum type system is more complicated, but the sample holder rotates around the center xenon lamp, and the test sample can obtain relatively uniform irradiation; the flat type system has a simple structure, but the sample plate is fixed. The test samples at different locations are not affected by irradiation.
