The development of electrodeless fluorescent lamps and their applications in lighting
Šenk, Tomáš ; Škoda, Jan (referee) ; Krbal, Michal (advisor)
The aim of this thesis is more familiar with electrodeless fluorescent lamps. In work is on introduction to the historical development of electrodeless fluorescent lamps, as is explained by their principle of operation and briefly discussed three basic design of these light sources. Subsequently there is mentioned some unique characteristics of electrodeless fluorescent lamps, which are different from other commercially available light sources. After explaining some light - technical variables. The work also provides a comparison of the parameters electrodeless fluorescent lamps with other available light sources. Further there are listed detailed parameters of several types electrodeless fluorescent lamps available in the Czech Republic. A description of possible applications in various types of light fitting. The next section describes the ballast system needed to supply the light sources. Below it is shown and described several start-up characteristics of the luminous flux of different types of electrodeless fluorescent lamps and various levels of compensation current drawn by induction lamps. There are also some parameters of available ballasts systems. Furthermore, given the possibility of applying electrodeless fluorescent lamps in extreme conditions. The conclusion is stated measurements of several cross characteristics of electrodeless fluorescent lamps.

Efficiency of Converting Electric Energy to Light in Current Light Sources
Krbal, Michal ; Pavelka, Tomáš (referee) ; Baxant, Petr (advisor)
The goal of this diploma’s thesis is to inform about present development of light sources, new technologies and about achieved parameters of these light sources. The thesis is mainly directed to describe efficiency of transformation electric energy to light at single types of light sources. There are described the concrete technical parameters of sources quoted by manufacturers and the contructional solution of single types of light sources. There is created a graphic comparation of electrotechnical and light parameters of the light sources.

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.
