Description

Technical Field

[0001] The invention relates to the technical field of aging test chambers, in particular to a xenon lamp aging test chamber. Background Art

[0002] Xenon lamps are electric light sources that emit light by discharging. Since the discharge material in the lamp is an inert gas called xenon, the difference between its excitation potential and ionization potential is small. Once the xenon lamp is ignited, it can achieve stable light output almost instantly. After the lamp goes out, it can be re-ignited instantly. Xenon lamp aging test chambers are widely used in the industrial field. In existing equipment for detecting product aging, high-power xenon lamps are usually used to simulate sunlight, because the light emitted by xenon lamps causes the product to age much faster than sunlight, thus increasing the detection speed. When performing aging tests in common xenon lamp test chambers, the irradiated object is generally fixed inside a tray, and the surface of the test object is irradiated with a xenon lamp. However, during irradiation, since the object is in a stationary state inside the tray, the side of the object cannot be effectively irradiated, thereby reducing the quality of aging detection.

[0003] In the prior art, there is an air-cooled xenon lamp aging test box with application number 202222627517.6, which includes a box body, a test cavity arranged in the box body, and also includes multiple xenon lamps arranged at the top of the test cavity, multiple exhaust ducts arranged at the top of most of the test cavities, and an exhaust main duct arranged at the back of the box body, and an exhaust duct is arranged between each two adjacent xenon lamps, and multiple exhaust ducts are connected to the exhaust main duct. By arranging multiple xenon lamps at the top of the test cavity and inserting exhaust ducts between adjacent xenon lamps, the xenon lamp illumination is more uniform, the cooling is more uniform, and the test results are more accurate. However, it is difficult to achieve all-round irradiation detection processing, which affects the efficiency of aging detection. Summary of the invention
