Design of the calibration box
Šácha, Tomáš ; Motyčka, Martin (referee) ; Škoda, Jan (advisor)
The diploma thesis deals with the description of basic photometric quantities, light sources and their parameters. The work also describes the LumiDISP luminance analyzer, for which the calibration box is designed. The next part of the diploma thesis deals with the design of the calibration box in the Inventor program and later the simulation of the calibration box in the Ansys Speos program. The simulations in Ansys Speos led to the determination of the number of light sources in the calibration box, which were then used for production. The work also describes the procedures and partial parts of the design and production of the calibration box, including its revitalization and testing.

Luminance scanning of luminaires and light sources
Ševčík, Ondřej ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
Práce se zabývá měřením křivek svítivosti světelných zdrojů a svítidel konvenčními a nekonvenčními metodami. Úvodní část práce je věnována popisu zrakového systému a základních fotometrických veličin. Hlavní teoretická část je zaměřena na popis současných metod měření křivek svítivosti a nových metod měření pomocí jasového analyzátoru. Současně jsou pro jednotlivé metody uvedeny zdroje nejistot, které ovlivňují výsledky měření. Těžiště práce spočívá v návrhu metodiky měření křivek svítivosti z jasových skenů svítidla a následném ověření tohoto postupu vlastním měřením. Dále bylo provedeno srovnání naměřených výsledků navrženým postupem, s výsledky konvenčního měření na goniofotometru s luxmetrem.

Evaluation glare of indoor and outdoor lighting systems
Rotrekl, Matěj ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
Recent years have seen an increasing focus on electric energy consumption as well as ecology in relation to human health. It is crucial to maintain the so called lighting comfort which is influenced by a wide range of lighting parameters, including illuminance, brightness, balance of illuminance, and glare. Thanks to all these parameters we can design lighting systems in such a way as to prevent energy waste and far too rapid deterioration of eyesight. This study therefore focuses on glare evaluation of indoor and outdoor lighting systems. In order to comprehend the issue thoroughly, a detailed description of human eyes and their functions is provided, followed by definitions of glare and types of glare. An overview of different calculations for indoor and outdoor glare is provided, considering the evaluation of daylight glare in terms of complex lighting systems. The study mentions several options involving unconventional methods for measuring glare (brightness). In the analytical part of the study, outdoor glare on Kolejní Street and indoor glare at the Prof. Brauner Hall at VUT measurements were obtained using brightness analyzer (an unconventional method). The thesis is concluded with a comparison of the conventionally and unconventionally obtained measurements, considering their respective advantages.
