Mísení RGB a bílých LED pro dosažení špičkových parametrů

Abstract

The aim of this thesis ,,Mixing RGB and white LEDs for best parameters achievement" in the first two chapters was ti describe the perceptual body, color perception and basic properties of LEDs, as yielding a white light, and spectral characteristics of LED dimming by different methods. The main point of this work was to build a controllable current source for independent control of up to four LEDs. It is used to measure the LED light sources in a spherical integrator. A practical measurement of color and white LED behavior was verified in mixing and dimming.

Measurements made at the source will help students with a demonstration of changes in color rendering index of temperature and other parameters chromaticity of LEDs in their dimming.
