Spectral assemblage using light emitting diodes to obtain specified lighting characteristics.

ABSTRACT

Light emitting diodes (LEDs) are considered next-generation light sources. Because of their narrow emission spectrum, easy adjustment, and various other characteristics, LEDs can be used in many situations, especially those that require dimming or spectral assemblage. In this paper we discuss spectral assemblage with LEDs. We cover possible valid arrangements in a spectrum from 400 to 700 nm by an exhaustive and genetic algorithm, calculate the highest luminous efficacy of a source for each correlated color temperature and color-rendering index, and present the corresponding energy distribution.
