Inovating methods for color fidelity index evaluation of LED.
Novák, Filip ; Škoda, Jan (referee) ; Motyčka, Martin (advisor)
This bachelor thesis is aimed to compare different methodologies of calculating color rendering indicators, because for modern light sources based on LED the traditional color rendering index Ra might be insufficient. The first part of this paper is based on explaining the basics, such as different methods of producing visible light, photometric quantities, or various CIE color spaces. The second and main part revolves around description of spectroradiometers, and calculation procedures for calculating color rendering indicators according to CIE 013.3-1995, CQS, IES TM-30-15, and CIE 224:2017. In the next chapter the mentioned indexes are then calculated for a given sample of light sources, and the results are subsequently evaluated.
