The scope of products
The destruction of materials by sunlight and moisture in nature causes an incalculable economic loss every year. The damage caused mainly includes fading, yellowing, discoloration, strength reduction, embrittlement, oxidation, brightness decrease, cracking, blurring and chalking. For products and materials exposed to sunlight directly or through the glazing, the risk of photodamage is large. Materials that are exposed to fluorescent lamps, halogen lamps, or other illuminating lamps for a long time are also affected by photodegradation.
The xenon lamp weatherproof test chamber uses a xenon arc lamp that simulates the full sunlight spectrum to reproduce destructive light waves in different environments. This equipment can provide environmental simulation and accelerated testing for scientific research, product development and quality control.
The xenon lamp weatherproof test chamber can be used for the selection of new materials, to improve existing materials or to evaluate changes in durability after changes in material composition. The equipment is a good model for simulating changes in the material exposed to sunlight under different environmental conditions.

Light intensity measurement and control
Light irradiance refers to the ratio of light energy that is incident on a plane. The equipment must be able to control the irradiance of the light to achieve the purpose of accelerating the test and reproducing the test results. Changes in light irradiance affect the rate at which material quality deteriorates, while changes in the wavelength of light waves (such as the energy distribution of the spectrum) also affect the rate and type of material degradation. The irradiation of the device is equipped with a light-sensing probe, also known as the sun eye, a high-precision metering system that can display the light energy degradation caused by the aging of the lamp or any other change. The sun's eye allows for the selection of the appropriate light irradiance during the test, and even the irradiance equivalent to the summer midday sun. The sun's eye can continuously monitor the irradiance in the irradiation chamber and maintain the irradiance at the operating set point by manually adjusting the voltage of the lamp. Due to long hours of work, when the irradiance drops below the set value, a new lamp needs to be replaced to ensure the irradiance is normal.
