Photobiological safety evaluation of light sources for household use
Jelínek, Jakub ; Motyčka, Martin (referee) ; Štěpánek, Jaroslav (advisor)
This thesis deals with the photobiological safety of light sources used for household lighting. The theoretical part of the thesis is devoted to areas related to photobiological safety, such as the basic description of vision functions, the description of light sources, as well as methods of measurement and evaluation. In the practical part, the spectrum of individual light sources is measured, from which the irradiance limits are calculated, according to which the source is assigned to the appropriate group of hazards.

Measurement of Discharge Light Sources Parameters
Štěpánek, Jaroslav ; Krbal, Michal (referee) ; Baxant, Petr (advisor)
The aim of my bachelor’s thesis is to provide a summary about discharge lights sources. It deals with their light and electric qualities. The work is divided into theoretical and practical part. The theoretical part pays attention to the construction of light sources; it provides information about photometric parameters and explores the connections the light sources into the power network. It describes the discharge lamp subtypes and subcategories. In practical part the quality of light sources is measured and the following results of measurement are evaluated.

Measurement of operating room lights quality
Rovná, Tereza ; Potočňák, Tomáš (referee) ; Harabiš, Vratislav (advisor)
This thesis is focused on measuring the quality of lighting in operating rooms. Operating lights are very demanding in terms of quality requirements for each parameter, so it is important to specify exactly these parameters and check them regurarly. To measure the quality of the light source, was used a special kit from Maquet. Measurement procedure was not as accurate as it was for operating lighting need, therefore, this work includes a proposal to improve the measurement of quality lighting in operating theaters. In cooperation with University Hospital Brno Bohunice University Hospital Motol and the company Maquet measured nine operating lights, each light were compared in terms of parameters such as maximum light intensity, light distribution in the surgical field. In each category were selected several lighting, which reached the best results. The various parameters were compared with values declared by the manufacturer.
