Abstract

Solar simulators are built using various types of light sources having a spectrum similar to that of the sun. Some of these light sources include but are not limited to Xenon Arc Lamps, Metal Halide Arc Lamps and Quartz Tungsten Halogen Lamps. Since these lamps showed several disadvantages related to high cost, light stability, temporal stability and complexity, the usage of high-power LEDs was proposed as a simple and low-cost alternative. This solution boosted the popularity of solar simulators in the field of optical characterization. An array of LEDs is used to create a light source based on mixing different LED's colors with different spectrums, to produce a spectrum similar to that of the sun with a very low mismatch factor. In this paper we will introduce our implemented design with which we managed to reach a 12% mismatching factor at a distance 10 cm from the light source.
