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.

Street Lighting Control
Kořenek, Jan ; Krbal, Michal (referee) ; Štěpánek, Jaroslav (advisor)
This bachelor thesis deals in a theoretical part with the origin of the light, his features and lighttechnical quantities. There are also characterized light sources, which are currently most used to control street lighting. There are further described basics of the street light and currently most used ways of street lighting control. Further part of this thesis is focused on practical control of different types of light sources and monitoring their parameters, such as luminous flux, power, efficiency or correlated colour temperature during voltage reduction. These light sources are high pressure sodium lamps, halogenid lamp, fluorescent lamp and high pressure mercury lamp. Main conclusion from measurements are several cross characteristics, where is possible to monitor behavior of the parameters during voltage reduction. The last part concerned about practical street lighting control in Bezděkov, which is a village located near Havlíčkův Brod. There was connected the dimmer. On the street was created net of points according to the standard. In these points were measured illuminance for voltage 230 V and then for lower voltages 210 V and 190 V. These values were processed and average and minimum value was compared with the value defined in the standard.

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.
