Xenon lamp weather resistance test box

Abstract

The invention provides an improved atmospheric exposure test chamber of xenon lamps, which has better testing accuracy and longer service life, comprises a case body with a working chamber and a controlling chamber arranged inside, and is characterized in that an irradiation sensor is arranged outside the working chamber.

Description

(1) Technical field [0001] The invention relates to the technical field of environmental test equipment, in particular to a xenon lamp weather resistance test chamber. (2) Background technology [0002] Weather resistance refers to the durability of polymer materials such as plastics, rubber, and coatings exposed to climatic conditions such as sunlight, cold, heat, wind, and rain. As the application of such materials has become more and more widespread in recent years, the requirements for them have become more and more stringent. So its durability test is imperative. The weather resistance test chamber mainly includes three types of equipment: xenon lamp, ultraviolet lamp, fluorescent lamp, and carbon arc lamp. They all simulate and intensify experiments from the main climate factors of light energy, temperature, rainfall or condensation. Xenon lamps and ultraviolet lamps can easily simulate the repeated alternating test conditions of daylight, night condensation or rainf...

AI Technical Summary

Problems solved by technology

[0004] In the traditional xenon lamp weather resistance test chamber, the light sensor is directly installed in the test chamber, see figure 1 , due to the high temperature and humidity in the test chamber 1, the sensor 4 is easily damaged, and the artificial rainfall in the test chamber 1 is tap water, which contains impurities. Due to the adsorption of impurities on the surface of the sensor 4, the irradiance intensity of the light source cannot be accurately tested
