Potenciál úspor vyplývající z použití moderních světelných zdrojů ve vnitřních pracovních prostorech

Abstract

This diploma thesis is to examine the potential of savings resulting from the use of power light-emitting diodes for illumination. There are the historical milestones in the development of light-emitting diodes, predictions of the values of performance parameters in this decade, including their definitions. There is included the principles of radiation in the light-emitting diodes and describe their properties. Below are listed the basic circuits, methods for driving the luminous flux of light-emitting diodes and influence on the qualitative and quantitative parameters. It is also designed diodes lighting system and compared the system with compact fluorescent lamps.
