Measuring of parameters dimmable LED sources
Kubeša, Radek ; Štěpánek, Jaroslav (referee) ; Baxant, Petr (advisor)
The bachelor thesis deals with the dimmable LED light sources. The theoretical part at the beginning is devoted to the light and the basic photometric quantities, analyzes the light sources and their parametres. It also describes the operating principle of LEDs, construction, power, and control the brightness of LED light sources. The practical part is focused on the measurement and evaluation of operating parameters selected samples of LED light sources.

Operating Characteristics of LED Sources
Brdečko, Aleš ; Diviš, Daniel (referee) ; Baxant, Petr (advisor)
This semester thesis is dealing with issues of LED (light emiting diod).In the text we can find general summary knowledges about LED, relating their history, construction, principle of working and also treatise about of semiconductor compounds. In thesis are given examples of use indicating their advantages and disadvantages and indicating their parameters. The practical content of this thesis is evaluation of measurement performed on some samples of LED especially graphics addiction of crosses and V-A characteristics measured in addiction on current.
