The aim of the project is to develop an innovative method of matching the spectrum of a halogen lamp to the spectrum of sunlight. This will allow for the creation of a prototype of a solar light simulator, characterized by low production costs and general availability of component light sources that fill the technological gap existing on the market. We will achieve this by using commonly used halogen lamps and LEDs, the spectrum of which will first be adjusted by an optical liquid filter and then mixed in a multi-fiber optical fiber. Thanks to this, the output spectrum falling on the sample will be matched to the spectrum of natural sunlight in class A specified by the IEC 60904 and ASTM E927-10 standards. The aim of the project is to develop a simulator in class AAA for spectral matching, stability of operation over time and uniformity of lighting. The last two parameters are ensured by the use of lamps powered by stabilized direct current and the use of an optical system reducing the numerical aperture of the optical fiber. The implementation of the product innovation described above will allow for the introduction to the market of a solar simulator with a wide range of applications, including: for environmental tests in research on the quality of agri-food products. In addition, sunlight simulators are used in research; dermatological, botanical, on photocatalysis and new photovoltaic materials.

We plan to implement the developed technological innovation in our own business activity, offering a fiber-optic sunlight simulator to research units primarily in Poland and European Union countries.
