The difference between water-cooled and air-cooled xenon lamp aging test chamber
The water-cooled xenon lamp aging box is cooled by the cooling water to the lamp tube. There is a drum sample holder inside, which rotates around the xenon tube. Therefore, 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;
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 Life is basically above 1600H
