Modular Led Luminaire With Variable Spectral Power Distribution Of Luminous Flux

Abstract

To date, development of luminaires is focused primarily on energy performance levels and accepted colour qualities of light output. Recent researches aimed to healthy and smart lighting showed that standard properties of luminaires are insufficient in terms of all performance levels required for modern illuminating systems. Dynamic change of intensity and colour temperature of light source during day is necessary for right function of human circadian system. Therefore it was developed modular LED luminaire allowing dynamic change of the spectral power distribution of luminous flux with possibility of colour temperature changing in the range 2400 K - 10 000 K (Ra >90, uv < 0.0005) and also possibility to set any hue in the colour gamut given by fixture construction.
