Thesis is focus on brightness control of lighting sources. The first objective of the thesis is to determine basic concepts and explain interrealationships among particular magnitudes of lifting technology. Further is necessary describe functionality, particular light sources and thein possibility of use in practise. There is also outline issue of darkfall of particular types of sources and their evolution. The other part of thesis compare energy output of lighting sources and describe their possible future development. Further this thesis deals with options of regulating of brightness for LED moduls. There is also proposal of acceptable amperage regulator LED moduls including its software - microcontrol ATMEL AVG. Microcontrol ATMEL AVG Ti...
