A New Colour Quality Model for Ultra-High Efficiency Light Sources with Discontinuous Spectra

This thesis demonstrates a novel approach to assessing the colour rendition of objects by high efficacy light sources. It establishes a relationship between a light source's output and the visual system, and develops a procedure to evaluate the colour quality of a light source based its fundamental spectral properties. Key wavelengths that link colour rendering and the human colour vision system are identified within. Furthermore, a predictive colour quality model based on the fundamental properties of a light source is presented, which is significantly different to existing, reference-based colour quality measures
