Xenon lamp aging test chamber simulates visible light test

Author:QINSUN Released in:2023-10 Click:33

The xenon lamp aging test chamber uses a xenon arc lamp that can simulate the full spectrum of sunlight to reproduce the destructive light waves that exist in different environments. Xenon Lamp Aging Test Chamber Natural sunlight and humidity damage materials, causing inestimable economic losses every year. The damage caused mainly includes fading, yellowing, discoloration, strength reduction, embrittlement, oxidation, brightness reduction, cracking, blurring and powdering, etc. Products and materials exposed to sunlight, either directly or through glass windows, are most at risk of the effects. photodamage.
Visible light is the part of the electromagnetic spectrum that can be seen by the human eye and is not part of the visible spectrum; the wavelength of electric wavesmagnetic waves that the average human eye can perceive is between 400 and 700 nanometers, but some people can perceive wavelengths of approximately electromagnetic waves between 380 and 780 nanometers.s. The human eye with normal vision is most sensitive to electromagnetic waves with a wavelength of approximately 555 nanometers, which are in the green light region of the optical spectrum. The range of light that the human eye can see is affected by the atmosphere. The atmosphere is opaque to most electromagnetic radiation, except for visible light bands and a few others, such as radio communication bands.
Visible light wavelength range: 390 ~ 760 nanometers.
Red light: wavelength range: 760 ~ 622 nanometers;
Orange light: wavelength range: 622 ~ 597 nanometers;
Yellow light: wavelength range wave: 597 ~ 577 nanometers;
GreenLight: Wavelength range: 577 ~ 492 nanometers;
Cyan light: Wavelength range: 492 ~ 450 nanometers;
Blue light: Wavelength range: 450 ~ 435 nanometers;
Violet light: Wavelength range: 435 ~ 390 nm.

In daily aging testing, different equipment may produce different test results. Test results will depend on the characteristics of the test sample and the design of the test equipment. Here is the xenon lamp aging test equipment. Some precautions:
1. The xenon lamp aging test equipment uses a xenon arc lamp as the irradiation light source. The test sample is installed in the test box, and the test conditions of the test sample must be consistent. The test equipment must be able to automatically control the irradiance, temperature of the blackboard, the air temperature of the box and the relative humidity in the box through a certain method.
2. Xenon lamp aging test equipment should be equipped with a blackboard thermometer or black mark thermometer.
3. The design of the xenon lamp aging test equipment should ensure that the irradiance at any position of the exposed area of ​​the test sample is at least 70% of the maximum irradiance in this area.
4. If the irradiation at the point furthest from the center of the exposed area is between 70% and 90% of the central irradiation, the test sample shall be placed in an area up to 90% of the maximum irradiation . Inside.
