The xenon lamp aging test chamber uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce destructive light waves in different environments, and can provide corresponding environmental simulation and acceleration tests for scientific product development and quality control. The xenon lamp aging test chamber can be used to select new materials, improve existing materials, or evaluate changes in durability after material composition changes. It can simulate the changes in materials exposed to sunlight under different environmental conditions.

According to different test methods in different fields, the choice of xenon lamp aging test box is also different. Many customers purchase the xenon lamp aging test box for the first time, which is very troublesome and does not know which one is more suitable for their own company. This chapter explains the difference between the air-cooled xenon lamp aging test chamber and the water-cooled xenon lamp aging test box for reference:

The air-cooled xenon lamp aging box cools the lamp tube by natural wind. The xenon lamp tube is located above the device, and there is a flat sample rack with adjustable height in the sample chamber. When the xenon lamp tube is used for a certain period of time, the sample holder and the xenon tube can be shortened. The distance to reach the specified irradiance, so the test box is also called the flat-type xenon lamp aging test box, which has lower energy consumption and longer service life, and the price is more expensive than the water-cooled lamp. The test chamber may have lower irradiance than the water-cooled xenon lamp aging box, but the service life of the air-cooled lamp is much higher than that of water-cooled, and the environmental requirements are not so high. The use of such a xenon lamp The life expectancy is basically above 1600H.

The water-cooled xenon lamp aging tank is cooled by the cooling water to the lamp tube. There is a drum sample holder inside, which rotates around the xenon tube, so it is also called a drum type xenon lamp. There is a water-cooled xenon lamp in the middle of the drum. The lamp has the characteristics of high energy efficiency, strong irradiance, relatively uniform irradiance received by the sample during the test, high energy consumption, inconvenient maintenance, and conductivity of the water source for cooling the lamp. , cleanliness, temperature, etc. have special high specification requirements, otherwise the surface of the lamp will be blackened and the lamp will be scrapped. The average service life of the xenon lamp is about 800H;

Air-cooled xenon lamp aging test chamber
1) Xenon lamp filtering: Filters are used to filter out short-light ultraviolet and infrared light.
2) Lamp: 3 imported lamps, the power of the lamp is 1.8KW/piece, and the effective service life of the lamp is about 1600h~1800h.
3) Sample holder structure: The sample holder is tray type, the sample tray size is 450×720mm, the height can be adjusted manually, the distance between the sample holder and the lamp: 230～280mm, there is no requirement for the shape of the tested product, as long as it can be placed on the sample Just on the tray.
4) Radiation intensity: Radiation intensity: ≤500W/m2, which is more suitable for "indoor products".

Water-cooled xenon lamp aging test chamber
1) Xenon lamp filtering: Filter the short-light ultraviolet and infrared light with a filter.
2) Lamp: 1 domestic lamp, the power of the lamp is 6KW/piece, and the effective service life of the lamp is about 500h~700h.
3) Sample holder structure: The sample holder is a rotary drum type rotary disc type, which can rotate 360°, but it has requirements for the shape of the product to be tested. It must be in the form of a sheet. The standard sample size is 75mm×150mm, and it is hung on the turntable for testing. .
4) Radiation intensity: Radiation intensity: ≤1120W±200W/m2, which is more suitable for “outdoor products”.
