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.

The change of the lighting approach in filmmaking with the arrival of LED technology
Nedvěd, Ondřej ; ŠEC, Martin (advisor) ; MYSLÍK, Jiří (referee)
LED lightning technology is relatively new element in the field of filmmaking. The aim of this thesis is to clarify how did the cinematographers‘ approach towards lighting change with the arrival of LED technology with regard to usability of LED sources in practice. The theoretical part of this thesis is going to analyze what are the technical benefits of LED lights in comparison to traditional light sources. The practical study describes the experience of the cinematographers who are using LED sources in practice. This thesis concludes that LED lights are able to compete with traditional light sources and are even able to exceed them in many ways.

The Use of LED Light Sources in Film and TV Lighting Technique
Brožek, Marek ; SMUTNÝ, Vladimír (advisor) ; MACÁK, Jiří (referee)
The purpose of this thesis is to provide a comprehensive overview of LED lighting equipment development and current trends in film and TV industry .
The thesis is divided into two parts. The first focuses on historical outline, physical and technical parameters of LED and also provides glossary of related terms.
The second part covers an overview of the development of LED technological solutions in manufacturing of film and TV lighting equipment, highlights their advantages and disadvantages, points out eventual problematic moments in using of LED lighting and presents the latest innovations of world leading manufacturers.
The conclusion sums up a general reflection on the future of LED technology.
