Description

Technical Field

[0001] The utility model relates to the technical field of xenon lamp aging test, in particular to a xenon lamp aging test box. Background Art

[0002] Xenon lamp light source emits light by discharging high-pressure or ultra-high-pressure xenon gas. Because its spectrum is similar to sunlight, it is also called primary sunlight simulator. Different series of xenon lamp light sources have different applications, and the output light intensity and spot size are different. Xenon lamp aging test chamber can simulate the xenon arc lamp of the sunlight spectrum to reproduce the destructive light waves existing in different environments, and can provide corresponding environmental simulation and accelerated tests for scientific research, product development and quality control. This test equipment can be used for the selection of new materials, improvement of existing materials or evaluation of durability changes after changes in material composition. The equipment can well simulate the changes caused by materials exposed to sunlight under different environmental conditions.

[0003] Most of the existing xenon lamp aging test chambers, due to the long-term operation of the xenon lamp tube, the lamp tube is prone to generate a lot of temperature, the xenon lamp tube needs to be cooled to extend the service life of the xenon lamp, and the existing cooling methods mainly use water cooling or air cooling. The air-cooled xenon lamp aging test chamber cools the lamp tube by natural wind, and the water-cooled xenon lamp aging test chamber cools the lamp tube by cooling water. The water cooling method requires regular maintenance of the water cooling pipe, and scale is easy to accumulate in the pipe, affecting the water cooling efficiency. In addition, the water cooling system is relatively complex and has a high maintenance cost. The air cooling method is easy to blow smaller dust or particles in the air into the storage bin, which is easy to affect the experiment. At the same time, the noise generated by air cooling is relatively large. It is necessary to design a xenon lamp aging test chamber to solve the above-mentioned problems. Utility Model Content
