MIL-STD-810 Solar Simulator Test Chamber Simulate Solar Radiation
Environmental
Product Information:
This Solar Radiation Aging Test Chamber (Metal Halide Lamp Aging
Test Chamber ) matches the requirements of MIL-STD-810, DIN 75220,
etc. It is used to simulate the irradiation requirements of the
environment inside and outside the vehicles.
It adopts full spectrum metal halide lamp, which is German OSRAM
SC4000, the spectrum curve of the metal halide lamp itself is very
close to the solar spectrum, and the sunlight can be completely
simulated after adjustment by a custom filter.
The sunlight simulation unit is composed of a lamp housing, a metal
halide lamp and an intelligent power supply. The intelligent power
supply is placed in the rear compartment of the test chamber, and
the metal halide lamp is installed in the lamp housing and arranged
in the test chamber according to the required irradiation area.
The lamp housing is made of sandblasted alumina board material, ,
the light emitting material is imported mirror bean grain aluminum
plate with a reflectivity of up to 97%. Extend the electroplating
process to ensure the high-strength hardness of the reflective
mirror surface, and reduce the occurrence of the situation that the
reflectivity is greatly reduced due to the later cleaning and
rubbing test.
Features:
A solar radiation test chamber, also known as a solar simulator or
solar radiation chamber, is a specialized testing equipment used to
simulate and replicate solar radiation conditions for evaluating
the performance, reliability, and durability of various products,
materials, or components under controlled environmental conditions.
It is commonly used in industries such as solar energy, aerospace,
automotive, and material science.
Key features and components of a typical solar radiation test
chamber include:
Light Source: The chamber is equipped with a high-intensity light
source, typically a xenon arc lamp or a halogen lamp, that emits
light across the solar spectrum, including ultraviolet (UV),
visible, and infrared (IR) wavelengths. The light source is capable
of producing a spectrum similar to natural sunlight.
Optical System: The chamber incorporates an optical system,
including mirrors, lenses, or filters, to distribute and control
the light intensity and spectrum. This ensures uniform and
controlled irradiance across the test sample or area.
Temperature Control: Solar radiation test chambers often feature
temperature control systems to maintain the desired test
temperature during exposure to solar radiation. This allows for
evaluating the effects of both solar radiation and temperature on
the tested materials or components.
Test Sample Holder: The chamber includes fixtures, racks, or
mounting systems to securely hold the test samples or devices in
the desired orientation while exposing them to solar radiation.
These holders ensure proper positioning and stability during
testing.
Irradiance Measurement: Sensors or radiometers are installed within
the chamber to measure and monitor the irradiance levels during
testing. This allows precise control and characterization of the
solar radiation intensity and spectrum applied to the test samples.
Control and Data Acquisition: Solar radiation test chambers are
typically equipped with a control system and data acquisition
system to set and monitor test parameters, such as irradiance
levels, exposure time, and temperature. This enables precise
control and data collection for analysis and comparison.
Solar radiation test chambers are used to assess the performance of
various products and materials under solar exposure, including
solar panels, photovoltaic cells, coatings, paints, polymers, and
electronic components. They can simulate different environmental
conditions, such as outdoor sunlight, different solar spectra, and
accelerated aging conditions, allowing manufacturers and
researchers to evaluate the long-term effects of solar radiation on
their products.
When conducting tests using a solar radiation test chamber, it is
essential to follow applicable standards, such as ASTM or IEC, and
specific test protocols to ensure accurate and reliable results.
These standards provide guidelines for test parameters, measurement
techniques, and acceptance criteria specific to the type of product
or material being tested.
