Xenon Lamp Weathering Test Chamber

• Introduction to Solar Simulation Irradiation Test Chamber

  Mar 07, 2025

  The Solar Simulation Irradiation Test Chamber, also known as the "sunlight radiation protection test device," is categorized into three types based on test standards and methods: air-cooled xenon lamp (LP/SN-500), water-cooled xenon lamp (LP/SN-500), and benchtop xenon lamp (TXE). The differences among them lie in test temperature, humidity, accuracy, duration, etc. It is an indispensable testing instrument in the series of aging test chambers.   The test chamber utilizes an artificial light source combined with G7 OUTDOOR filters to adjust the system's light source, simulating the radiation found in natural sunlight, thereby meeting the requirements for solar simulators as stipulated in IEC 61646. This system light source is employed to conduct light aging tests on solar cell modules in accordance with IEC 61646 standards. During the testing, the temperature on the back of the modules must be maintained at a constant level between 50±10°C. The chamber is equipped with automatic temperature monitoring capabilities and a radiometer to control the light irradiance, ensuring it remains stable at the specified intensity, while also controlling the duration of the test.   Within the solar simulation irradiation test chamber, the period of ultraviolet (UV) light cycling typically shows that photochemical reactions are not sensitive to temperature. However, the rate of any subsequent reactions is highly dependent on the temperature level. These reaction rates increase as the temperature rises. Therefore, it is crucial to control the temperature during UV exposure. Additionally, it is essential to ensure that the temperature used in accelerated aging tests matches the highest temperature that materials would experience when directly exposed to sunlight. In the solar simulation irradiation test chamber, the UV exposure temperature can be set at any point between 50°C and 80°C, depending on the irradiance and ambient temperature. The UV exposure temperature is regulated by a sensitive temperature controller and a blower system, which ensures excellent temperature uniformity within the test chamber.   This sophisticated control over temperature and irradiance not only enhances the accuracy and reliability of the aging tests but also ensures that the results are consistent with real-world conditions, through this Solar Simulation Irradiation Test Chamber, which can provide valuable data for the development and improvement of solar cell technologies.

• Conversion Between Accelerated Aging of Xenon Lamp Aging Test Chamber And Outdoor Aging

  Nov 08, 2024

  Conversion Between Accelerated Aging of Xenon Lamp Aging Test Chamber And Outdoor Aging  Generally speaking, it is difficult to have a detailed positioning and conversion formula for the conversion between accelerated aging of xenon lamp aging test chamber and outdoor aging. The biggest problem is the variability and complexity of the outdoor environment. The variables that determine the relationship between xenon lamp aging test chamber exposure and outdoor exposure include: 1. Geographical latitude of outdoor aging exposure sites (closer to the equator means more UV). 2. Altitude (Higher altitude means more UV). 3. Local geographical characteristics, such as the wind can dry the test sample or close to water will produce condensation. 4. Random changes in climate from year to year can lead to a 2:1 change in aging at the same location. 5. Seasonal changes (e.g., winter exposure may be 1/7 of summer exposure). 6. Direction of the sample (5° south vs. vertical facing north) 7. Sample insulation (outdoor samples with insulated backing age 50% faster than uninsulated samples). 8. Working cycle of xenon lamp aging box (light time and wet time). 9. The working temperature of the test chamber (the higher the temperature, the faster the aging). 10. Test the uniqueness of the sample. 11. Spectral Intensity Distribution (SPD) of laboratory light sources Objectively speaking, accelerated aging and outdoor aging have no convertibility, one is a variable, one is a fixed value, the only thing to do is to obtain a relative value, rather than an absolute value. Of course, it is not to say that relative values have no effect; on the contrary, relative values can also be very effective. For example, you will find that a slight change in design may double the durability of standard materials. Or you may find the same looking material from multiple suppliers, some of which age quickly, most of which take a moderate amount of time to age, and a smaller amount that ages after longer exposure. Or you may find that less expensive designs have the same durability against standard materials that have satisfactory performance over actual service life, such as 5 years.

• How Long Is the Xenon Lamp Weathering Test Chamber Equivalent to a Year of Outdoor Exposure?

  Nov 07, 2024

  How Long Is the Xenon Lamp Weathering Test Chamber Equivalent to a Year of Outdoor Exposure? How long is the xenon lamp weathering test chamber equivalent to a year of outdoor exposure? How to test out its durability? This is a technical problem, but also a lot of users are concerned about the problem. Today's engineers of Lab Companion are going to explain this problem. This problem looks very simple, in fact, it is a complex problem.We can not just get a simple number, let this number and the test time of the xenon lamp weathering test chamber to multiply, so as to get the outdoor exposure time, nor is the quality of our xenon lamp weathering test chamber not good enough! No matter how good the quality of the xenon lamp weathering test chamber is, how advanced it is, it is still impossible to find only a number to solve the problem. The most important thing is that the outdoor exposure environment is complex and changeable, affected by many factors, what are the specific? 1. The influence of geographical latitude 2. The influence of altitude 3. The influence of geographical environment when testing, such as wind speed. 4. The impact of the season, winter and summer will be different, summer exposure is 7 times the damage of winter exposure. 5. Direction of the test sample 6. Is the sample insulated or uninsulated? Samples placed on insulators will generally age much faster than those not placed on insulators. 7. Test cycle of xenon lamp weathering test chamber 8. Xenon lamp weathering test chamber operating temperature, the higher the temperature, the faster the aging 9. Testing of special materials 10. Spectrum distribution in the laboratory
