I. Overview of Xenon Lamps Aging Test Chamber:
Dongguan Hongjun Instrument & Equipment Co., Ltd.'s HJ/CQ Series Xenon Lamps Aging Test is a comprehensive climatic test device. In addition to climatic aging tests, it can also test the optically rotating resistance of high-grade materials, evaluating the material's resistance to optically rotating under artificial light sources simulating sunlight passing through glass. It simulates and enhances tests from several primary climatic factors: light energy, temperature, rainfall or dew, and humidity. It uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce destructive light waves present in different environments. The Xenon Lamps Climatic Test Chamber provides corresponding environmental simulation and accelerated tests for scientific research, product development, and quality control. It is applicable for tests such as selecting new materials, improving existing materials, or evaluating the durability changes after material composition changes, and is suitable for plastics, rubbers, paints, coatings, inks, papers, food, textiles, automotive parts, packaging materials, building materials, electronic electrical products, and more.
The Xenon lamp test chamber employs a xenon arc lamp capable of simulating the full sunlight spectrum to reproduce destructive light waves present in various environments. It provides environmental simulation and accelerated testing for scientific research, product development, and quality control.
The SN Xenon Lamps Test Chamber is suitable for tests such as selecting new materials, improving existing materials, or evaluating changes in material durability after composition modifications. It effectively simulates the changes that materials undergo when exposed to sunlight under different environmental conditions.
Simulate full sunlight spectrum:
SN measures the material's resistance to polarization by exposing it to ultraviolet (UV), visible light, and infrared light. It uses filtered xenon arc lamps to generate a full sunlight spectrum that closely matches natural sunlight. The method of using properly filtered xenon arc lamps is to test the product's sensitivity to longer wavelengths of UV and visible light in direct sunlight or sunlight passing through glass.
Optical Rotation Resistance Test for Indoor Materials
Due to prolonged exposure to fluorescent lights, halogen lamps, or other luminous sources, products placed in retail outlets, warehouses, or other environments will also undergo significant photo-degradation. The SN Xenon Light Test Chamber can simulate the destructive light in such commercial lighting environments and accelerate the testing process by generating light at a higher intensity.
Simulated Climate Environment:
In addition to the photo-degradation test, the SN Xenon Lamps Test Chamber can be converted into a climate aging test chamber by adding a water spray option, simulating the effect of outdoor humidity on materials.
Relative Humidity Control
Some models of SN Xenon Lamps Test Chambers offer relative humidity control functionality, which is crucial for many materials sensitive to humidity, and many test protocols also require humidity control.

Rain Shower System
The rain system is mainly composed of nozzles, solenoid valves, water supply sources, and connecting hoses.
Lighting System:
The lighting system is primarily composed of xenon lamp tubes, lamp shades, xenon lamp triggers, and various control devices. Energy compensation for the xenon lamps is achieved by adjusting the distance between the mounting frames and by regulating the voltage and current.
Air Duct System
The duct system is located in the cavity at the rear of the test chamber, housing devices such as heaters, fan blades, evaporators, and PT100 temperature sampling sensors. As the fan rotates at high speed, it draws air from the top of the work chamber into the duct, where it is thoroughly mixed with the heat generated by the heater and the cooling produced by the evaporator before being blown out from below. The air that has exchanged heat with the test sample is then drawn back into the duct for further mixing; this process is repeated to achieve the desired temperature and ensure the test chamber maintains high humidity levels.
Cooling / Dehumidification System
We choose the "Tecumseh" fully enclosed industrial refrigeration compressor from France. Mainly used for cooling the xenon lamp tubes and maintaining a constant indoor temperature and humidity level in the workspace.
Humidifier section:
Steam generator: Equipment that produces steam by vaporizing water.
Water Level Control: Electromagnetic valve controls water intake, liquid level switch controls water level, providing signals for humidifier water addition and alarm.
Gas Recirculation Section:
Equipped with an internal circulating air duct and fan, utilizing high-efficiency refrigeration units and an energy regulation system, the effective heat exchange is achieved through high-efficiency fans to achieve temperature variation. By improving the air blowing flow, the air flow and the heat exchange capabilities of the heating, humidifying, and air cooling units are enhanced. The uniformity of temperature and humidity within the test chamber is significantly improved through adjustable air outlet nozzles.
