Weather resistance test chamber for air-cooled xenon lamps

Air-Cooled Xenon Lamp Weatherability Test Chamber is a machine that uses air to dissipate the overload heat given off by the xenon lamp tube. The xenon lamp aging test box is slightly cheaper. One or more air-cooled xenon lamp tubes are installed on top of the aging test chamber. In this system, the filter is flat, hence it is sometimes referred to as a flat xenon lamp aging test chamber. The filter is placed under the lamp tube, and the top and side of the test chamber are installed Uniformity of radiation distribution. Samples to be tested are placed on a sample grid shelf below the lamp tube. The flat sample grid layer is slightly tilted at a small angle to facilitate water flow when spraying water or condensed water.

The air-cooled xenon lamp aging test chamber is widely used to measure light stability and weather resistancetivity of industrial materials and industrial products, as the spectrum emitted by the xenon lamp is very close to the full spectrum outdoors including ultraviolet light (UV), infrared (IR) solar spectrum and visible light. To obtain accurate and repeatable test results, any light stability or aging test must control light quality. Changes in light intensity affect the rate of damage to industrial materials, while changes in spectral energy distribution affect material degradation. speed and type. Therefore, this xenon lamp aging test chamber can bring predictive testing to customers very well.

The protection devices of the air-cooled xenon lamp weather resistance test chamber include phase protection devices, cooling system overpressure protection devices, fan overheating protection devices, cooling system overload protection devices, overtemperature protection device,s and other devices such as leakage and water shortage indicators. After an error alarm occurs, the device will stop automatically to avoid loss of control and cause greater damage.

 

The main factors for material aging in the air-cooled xenon lamp aging test chamber are sunlight and moisture hazards from dew. Simulate the effects of sunlight with xenon lamps, and rain and dew with condensed moisture. Tested materials are placed in a light-humidity cycle at a specific temperature for testing and can be reproduced outdoors in a few days. When exposed to months or even years of exposure, data from artificially accelerated aging tests can help select new materials to replace existing materials and modify and evaluate how formulation changes affect product lifespan.
