Theoretical part of this thesis describes LEDs and other circuitry used for LED light design. LED light is designed, manufactured and put into operation. This thesis examines possibilities of measuring exterior light and its key parameters. The device uses two sets of LEDs – warm white and cold white to create light with parameters dependent on exterior light. LEDs are driven by constant current sources that are designed, manufactured and examined in this thesis. The device is microprocessor-controlled, which allows to switch between multiple modes of operation. Flyback SMPS is used to power the microcontroller. |
