Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.

Energy Optimization and Operation of Public Lighting
Houdek, Michal ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
An objektive of this university graduation work is an essay about any possibilities for energy savings with operation optimalization of public lightings. Understandings and introduction operation problems of public lighting is devote in first part of this work. Here we can chapters as Importance of public lightings or Gulations and norms in ralation to public lightings. The bigist and special attention is concentrated to description to public lightings systems and it is basic components. Another main part of this work is demonstration of used systems that are leading to energy savings for public lightings. These problems are detailed and explained in chapter Regulation of public lighting systems. This graduation work is describing individual types of regulation with the systems that are used with these regulatios in systems of public lightings. The assignment of last part of graduation work was to make sample calculation of energy demand and calculatin of yearly consumption on exemplary temporary system of public lightings. For this occasion was extra special auxiliary application sytem set up inside the Microsoft Excel program where all individual calculations were done.

Brightness control of light sources
Dostál, Lukáš ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
Thesis is focus on brightness control of lighting sources. The first objective of the thesis is to determine basic concepts and explain interrealationships among particular magnitudes of lifting technology. Further is necessary describe functionality, particular light sources and thein possibility of use in practise. There is also outline issue of darkfall of particular types of sources and their evolution. The other part of thesis compare energy output of lighting sources and describe their possible future development. Further this thesis deals with options of regulating of brightness for LED moduls. There is also proposal of acceptable amperage regulator LED moduls including its software - microcontrol ATMEL AVG. Microcontrol ATMEL AVG Tiny 13 is programme in C language within computer environment AVR Studio 4 and will be record through the use of AVR Dragon.

LED technology for Lighting Plants
Pospíšil, Tomáš ; Pavelka, Tomáš (referee) ; Krbal, Michal (advisor)
The aim of the work is to describe the physiology of plants and their needs to the successful evolution and growth. Furthermore to introduce a characteristic light requirement of plants and summarize differences between light requirements of the human eye and plants. More there are shortly mentioned the light quantities and units and by means of these quantities and their units there is assessed the appropriateness of lighting for plants. Another aim is to describe the electric and lighting-technical LED parameters that are suitable for use as a lamp designed for illumination of plants, outline the basic requirements that should the lamp designed for illuminating the plants fulfill. The last part is devoted to the presentation and evaluation of the measurement results of the lamp, which was already developed and used on prototype light source using LED.

Electrical installations in apartment building
Novotný, Jan ; Formánek, Marian (referee) ; Doležalová, Jana (advisor)
This bachelor's thesis deals with electrical wiring in apartment building. The aim is to describe the types of distribution networks, implementation possibilities of service lines, describe the individual parts of the wiring in the building and the principles of their implementation. Further describe basic electrical materials and to explain the design of artificial lighting. In the practical part the information applied to a particular apartment building, together with the calculation of the estimated annual energy consumption of flats. For the apartment building project is created in the form of engineering report and drawings.

Design of lighting system in high school
Borůvka, Jan ; Štěpánek, Jaroslav (referee) ; Škoda, Jan (advisor)
The theoretical part is focused on lights, notions and calculations in the area of light technology, basic lightning sources and lamps. This work is also about the principle of lightning measuring. The main aim of the work is design of a new artificial lightning system in a High school agriculture in Prerov. At first, the control measuring of existing lightning was done which is mentioned in this work. From the results of control measuring is clear, that existing lighting system in classroom does not suit requirements, which are mentioned in the valid technical norm. Design of a new lightning system meets the requirements in all of the rooms in the building of school. Design of lightning system was done in two variants. The first variant uses lamps with fluorescent tube light sources. The second variant uses lamps with LED light sources. Also is here evaluated financial difficulty of possible installation and comparation of each variants with respect energetic difficulty.

Electronic ballast for sodium lamp
Eliáš, Jaroslav ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
The aim is to get acquainted with the way the management and regulation of sodium lamps. This knowledge is then applied to design your own gear. The introductory section describes the basic characteristics of discharge light sources. Their behavior was verified by measuring and findings were used to create diagrams, mainly the control circuit. Theoretical design is developed by individual functional parts of the inverter.
