Abstract

Spectral power distribution together with color consistency and constancy of natural light is studied and simulated before the white-light LED systems are fabricated to reproduce the natural light. The model with 3, 4, 6 and more primary LEDs based on the real measured spectrum and theoretical spectrum are analyzed. The spectral power sensitivity relation between the LEDs with different wavelength and color characteristic is analyzed. This research simplifies the approach of visible spectrum reconstruction which is an efficient way to use in the design and realization of LED-based luminaire.
