The measurement of melanopic quantities in indoor spaces with the luminance analyser LDA - LumiDISP
Siegel, Josef ; Baxant, Petr (referee) ; Motyčka, Martin (advisor)
This thesis focuses on measuring melanopic quantities in indoor spaces and their impact on individuals and their circadian rhythms. Melanopic quantities are specific parameters of light that influence biological responses and physiological processes in our bodies. To measure these quantities, a photometric analyzer is utilized, enabling the quantification of spectral components of light. It also evaluates the melanopic contributions of various lighting sources, such as LED fixtures, incandescent bulbs, or natural daylight.

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.

Controlled lighting and shading in smart house
Novák, Michael ; Morávek, Jan (referee) ; Bátora, Branislav (advisor)
This bachelor‘s thesis is focused on controlling lighting and shading in a smart house. Lighting control covers switching and dimming mechanisms. This thesis presents dimming options for different types of light sources. Following this is an overview of shading devices and system wiring, often called smart wiring. Specifically, the thesis focuses on the Foxtrot system from Teco a.s.. This work describes the sensors and actuators used for switching, dimming and shading control devices. New library of functional blocks for lighting and shading control for Foxtrot system was created, for they were not included in any standard library. All functional blocks that have use in the control of lighting or shading - including standard ones - are described in this work.

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.

Design and construction of an interactive light sources panel
Žák, Martin ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
This semestral thesis deals with design and construction of the interactive light sources board and measurement of various parameters of those light sources. Using the given requirements, a solution is worked out (construction materials, behaviour, design, wiring etc. are given). Based on this, the interactive board was also constructed and put into operation. The thesis is also focused on the given light sources themselves (incandescent light bulbs, halogen lamps, compact fluorescent lamps, fluorescent tubes and LED lamps) and their measurement results are presented.

Simulation model of public light for Network Simulator 3
Kapoun, Vladislav ; Mlýnek, Petr (referee) ; Fujdiak, Radek (advisor)
This thesis is focused on the smart public lighting management possibilities. It describes smart public lighting management itself and the advantages of the new management possibilities compared to the current ones are illustrated as well. Furthermore, it deals with a comparison of the most used light resources and LED light resources. This thesis also outlines NS-3 simulation environment and states its advantages. Theoretical concept for energy-saving smart public lighting management system and its modifications for the needs of simulation is described in the paper. This theoretical concept is simulated and compared with the current smart public lighting management systems as well as with the systems designated by the third party.
