The tube lights starter
Růžička, Jakub ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
This thesis is about design of the electronic ballast used for starting and dimming six 40 W fluorescent lamps. Controlling is provided by button and analog input. In the work it is used micro-controller which controls excitation circuit of transistors in the half-bridge driver IR2104. The electronic ballast is created for two fluorescent lamps with possibility to add other modules. Behavior of the ballast was simulated, and then it was measured on constructed devices.

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.
