Hierarchical Techniques in Lighting Computation
Ligmajer, Jiří ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This master thesis deals with description of hierarchical techniques in global lighting computation. Here is explaining the importance of hierarchical techniques in lighting computation and shows method, how to use these hierarchical techniques in realtime radiosity and its extension to dynamic area lighting. These two techniques are described in detail in the first part of this project. In the other part is desing and implementation of application for dynamic area lighting computation.

Electronic ballast for power LEDs
Vágner, Richard ; Martiš, Jan (referee) ; Červinka, Dalibor (advisor)
This diploma thesis deals with design of power LED driver. This driver contains electronic ballast circuits, converters, filters and control circuits. Overviews of circuits used in practice are listed along with analysis of power LED and considering options for selecting an appropriate design solution. Principles of creating the device, structure and problems of current source are described in thesis. Including detailed overview of converters, ballasts and topologies used in lighting systems with the selection of a suitable solution for the final device with an output power of 50 W. The thesis includes cooling dimensioning for selected power LEDs, input circuit with EMI filter, bridge rectifier, boost converter and flyback converter with pulse transformer.

Modern LED luminaire concept for road lighting
Krejčí, Miroslav ; Kovářová, Klára (referee) ; Novotný, Jan (advisor)
This thesis deals with design of optical system for road lighting luminaire. In the beginning the basic photometric quantities and assessment methodology for requirements of lighting class M are described. The next step is the programming of algorithm which evaluates the road lighting requirements using few boundary conditions. The input of the algorithm is also luminous intensity (power emitted in a particular direction). By the turning the algorithm over, it is possible to evaluate the luminous intensity from the road lighting requirements. Those luminous intensities are used in the process of modification of optical lens. The ray tracing of modified models of lenses was performed to obtain the tables of luminous intensity. The values of luminous intensity are verified in the same algorithm. Finally, the comparison of results was made including several luminaires out there.

Polyfunctional house
Kuklová, Jana ; Pilný, Ondřej (referee) ; Berková, Petra (advisor)
The main aim of the thesis is to design a new building of the mixed-use building in Brno. The building consists of two parts. One part consists of shops. The second part consists of offices and conference space. It is a building that has three floors above ground and one underground. In the basement there are a facilities and a garage. Shops are designed on the ground floor. There are offices on the second floor. Conference rooms are on the third floor. The building has a flat roof. The vertical load-bearing structures are designed from Porotherm ceramic blocks. In the core of the building, the vertical load bearing structures are designed as monolithic reinforced concrete walls. Columns are used in the building for the possibility of open space. The masonry of the basement consists of white bathtub. The floors are designed as folded from the Spiroll system. Internal non-load-bearing walls are designed from gypsum board with double cladding. The second part of the work deals with forced ventilation, cooling and central heating. In the third part of the project I deal with acoustics. The project was carried out in the Auotocad program. All constructions comply with valid standards and regulations.

Control of smart house model
Becová, Lucia ; Arm, Jakub (referee) ; Štohl, Radek (advisor)
My thesis deals with the control of intelligent and comfort house. The first chapter contains a model of the irrigation system , recovery of the electronics and simple applications for testing. The second chapter deals with the recovery model of gate and garage doors. The third chapter is focused on the management of lighting in the house and its surroundings. The fourth chapter is devoted to visualization via the Power Panel PP481.

Printed light dosimeter for galleries
Škarvadová, Adéla ; Klusoň, Petr (referee) ; Veselý, Michal (advisor)
This bachelor thesis deals with the lighting of the gallery space and the measurement of light intensity inside. The subject of the experimental study are photosensitive composition for the production of disposable printed and thin-film dosimeters for galleries and museums. Kinetic color change of the two systems using two dyes and calibration components was examined. The composition for printing was optimized and dosimeters were prepared with a wide range of light exposure causing a significant color change of the dosimeter, and that from 1,7 klx•h to 200 klx•h.

Architectural lighting and desing particularity
Haluza, Miroslav ; Maixner, Tomáš (referee) ; Baxant, Petr (advisor)
The goal of this thesis is make a list of theoretic routes outside (architectural) lighting and draw up accessible light fitting. Further are in those work included principle for handy suggestion architectural lighting after technical norms and practical recommendationthat the is necessary at projection hereof lighting adhere. Last but not least is here mentioned problems installation and upkeep architectural lighting and safeness and immunity electric arrangement.
