Evaluation of LED replacements
Bordovský, Lukáš ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
The aim of my thesis is to become familiar with LED replacements of light sources, possible problems, advantages and disadvantages. In the work are at first explained terms of light technology. Then are concisely described actual light sources, that can be replaced by LED. That concern: classic bulbs, halogen bulbs, linear fluorescents and compact bulbs. After that is described principle of LED light fittings and advantages, disadvantages nowadays to use LED light fittings. The main emphasis is placed on chapter 5. The compensations of linear fluorescents by LED moduls. The following chapters are dedicated to comparison of fluorescent lamps and LED moduls. Involving-photometrics parameters, luminous intensity, lumniance analysis and also economics comparison of lighting systems with fluorescent lamps versus the LED moduls.

LED lamps clasification regarding voltage flicker sensitivity
Štefek, Roman ; Baxant, Petr (referee) ; Drápela, Jiří (advisor)
The master's thesis deals with the design and time optimization of the method designed to determine the classification of LED lamps due to their resistance to power supply fluctuations. Classification of LED lamps in the classification scale and their labelling by the classification index is the task of informing in a simple way those interested in the ability of a concrete light source to function properly, without disturbing flickering, in conditions of electromagnetic interference.
