| Abstract [eng] |
The aim of this work is using different color temperatures white light and color LEDs, design and investigate LED lighting system, which can control lighting parameters. In order to implement this objective, it is necessary to solve such problems. The first two chapters of the work carried out a literature review. There was found out the general LED parameters and characteristics. In the third chapter there is LED color modeling, for designed system selected warm and cold white light, red, lime green LEDs. There was made a structure of controlled lighting system components, which was investigated and modeled on the fourth, fifth and sixth sections. Also there was made control signals formation and processing algorithm, developed control program for managing the lighting system remotely. Also developed management smartphone application for Android and iOS operating systems. Developed different power Buck converters. Using software “MicroCap 10” was modeled and tested current control of converter, transistor’s and other characteristics of Buck converter. The seventh chapter consecrated in LED lighting system realization and experimental research. Using the software "CADSOFT Eagle 8.1.0" modeled and designed power supplies and LED printed circuit board. There was made the experimental researches of controlled parameters LED lighting system. Using photometric integrating sphere and software "Everfine" measured the lighting system parameters. Work generalized conclusions. |
