The Difference Between Xenon Lamp Aging Test Chamber And UV Aging Test Chamber

The Difference Between Xenon Lamp Aging Test Chamber And UV Aging Test Chamber

Issue Time:2017/06/04

Natural climate light aging test methods are usually divided into two kinds, the first is to simulate the UV aging, the second is to simulate the whole sun aging.


1, UV light irradiation test method

UV light irradiation aging test using fluorescent UV light to simulate the destruction of sunlight on the destructive effects of durable materials, fluorescent UV lamp in electrical principle and ordinary lighting with cold light fluorescent lamp similar, but can generate more ultraviolet light rather than visible light Or infrared light.

For different exposure applications, there are different types of lamps with different spectra for selection. The UVA-340 lamp simulates the sunlight well in the main short-wavelength UV spectrum. The spectral energy distribution (SPD) of the UVA lamp is very similar to that of the spectrum at 360 nm from the solar spectrum. UVB lamps are also commonly used to accelerate the artificial climate aging test lamps. It is faster than the UVA type of light on the destruction of the material, but it is shorter than the 360 nm wavelength of energy output for many materials will cause deviations from the actual test results.


2, xenon arc radiation test method

The xenon arc radiation test is considered to be the most able to simulate the whole solar spectrum test, because it can produce ultraviolet light, visible light and infrared light.

But this method also has its limitations, that is, xenon arc light source stability and the resulting complexity of the test system. The xenon arc light source must be filtered to reduce unwanted radiation. There are a variety of filter glass types to choose from for different irradiance distributions. The choice of glass depends on the type of material being tested and its end use. Changing the filter glass can change the type of short wavelength ultraviolet light that is transmitted, thereby changing the speed and type of damage to the material.


The xenon lamp illuminates the test chamber to imitate all the solar spectrum, including ultraviolet light, visible light and infrared light, and its purpose is to simulate the sun. The UV light aging test does not attempt to imitate the sun, but only to imitate the destruction of the sun effect. It is based on the principle that long-term exposure to outdoor durable materials, by short-wave ultraviolet light caused by the greatest damage to aging.
