Selection of white light-emitting diodes with similar color characteristics for lighting systems

摘要

Reproducibility of colorimetric measurements of light-emitting diodes is researched in case of application of digital Altering of a signal. Influence of methods of digital filtering of a signal on the quality of a received spectrum of radiation is shown. Results of researches of color characteristics of light-emitting diodes of the ceiling lamp are given. Distinctions in color coordinates for pairs of light-emitting diodes being perceived equally and differently are demonstrated. The selection term of light-emitting diodes for lighting system on the basis of their color coordinates is shown.
