Evaluation of Lighting Quality Using Modern Software Tools
Fazekas, Tibor ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
This thesis deals with the evaluation of the quality of lighting with the usage of the latest software products used nowadays. The first part of the work is about indoor lighting, the basic requirements invested in lighting, and the basic concepts of indoor lighting. The second part includes complete search for today's computer implements for projecting, simulating, calculation and analysis of light, their functions and characteristics, including luminance analyzers based on CCD sensors and their software equipment. The last part of the work has the task to model a computer room using softwares which can be found within the territory of VUT Brno, and the task was to assess its lighting. Following this, with the help of luminance analyzer, the task is to capture the scene under different lighting conditions and to evaluate the measured data.

Glare measurement with a luminance analyser
Kalfus, Petr ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
One of the basic parameters of any lighting is the quality of the illumination design, and how it glares. This paper deals with glare and its evaluation. The basic variables used in its evaluation are described. Methods of evaluating internal glare using various indexes are described. Methods of evaluating glare from daylight and evaluating glare of outdoor systems are also described. The principle of operation of luminance analysers is then described and the school LDA luminance analyser that will be used for the measurements is described. The indoor glare measurements made are described, manually evaluated and calculated and compared with the new automated calculation in the lumiDISP program. The daylight glare and outdoor glare measurements are also described, evaluated and compared with the new automated calculation. Finally, the possibility of measuring glare with a luminance analyser is summarised and the accuracy of the new lumiDISP functions is evaluated

Use of Luminance Analyser for the Quantification of Artificial Light at Night
Novák, Filip ; Motyčka, Martin (referee) ; Baxant, Petr (advisor)
This diploma thesis deals with obtrusive light and its measurement, especially with the help of luminance analyzers. In particular, the necessary theoretical basis for the design of a measuring methodology for obtrusive light or veil brightness of the sky is laid here. This mainly includes the division of obtrusive light and its manifestations, a description of the effects of obtrusive light on the environment, selected organisms and the human body. Also described herein are the biological mechanisms of the human body that are affected by light as such. Attention is also paid to streetlights, its classification and methods of reducing obtrusive light, as well as methods of measuring brightness and brightness analyzers. Last but not least, the night sky is also measured using the LumiDISP luminance analyzer and subsequent data are evaluated using the proposed method.

Plunging Brno into darkness: Measuring the contribution of public lighting to the total luminance of the night sky
Novák, F. ; Baxant, P.
The article deals with the description of measurements of night sky luminance in urban agglomeration with emphasis on the determination of changes in the values of these luminances when public and architectural lighting is temporarily turned off. The measurements took place in Brno, the second largest city in Czech Republic, with the population around 382 thousand. The presented paper is one of the perspectives on the impact of human activity on the surrounding environment and an example of a possible solution to quantify the impact of the introduction of technologies that directly or indirectly affect the environment not only for humans, but also for almost all forms of life.
