In 1918, the world's first rotating drum xenon aging test chamber appeared. It used a carbon arc lamp as the light source. The light source or tube was placed vertically in the center of the instrument with a filtering system around it. The test sample is mounted towards the light source and rotates around the center light like a conveyor belt. Since the First World War, this test chamber has been continuously improved, but its basic design principles have not changed. The lamp cooling system of the most common xenon lamp aging test chamber is water cooled. This type of water-cooled xenon arc test chamber is called "rotary drum type".
In recent years, a new type of static sample placement xenon lamp aging test chamber has appeared, and three air-cooled xenon lamps have been installed at the top of the test chamber. In this system, the filter is of the flat type and is placed in the lower part of the tube while a reflective system is placed on the top and sides of the test chamber to enhance the uniformity of the irradiance. The test sample is mounted on a sample tray below the tube. The tray is slightly tilted at a small angle to allow water to flow away. This type of test chamber is referred to as a "flat" type.
Note: Rotating drum type xenon lamp aging test box is also called water-cooled xenon lamp aging test box (model: YSL/SN-900). Flat-type xenon lamp aging test box is also called air-cooled xenon lamp aging test box (model: YSL/SN-500).
