Spectral vision of a colour scene is determined by the product of the spectral power distribution of the light source, the spectral radiance (reflection) factor of the scene components and the photopic spectral visibility or V() curve. With the introduction of LED lighting, the lighting industry is faced with an infinite number of colour sources of light with numerous SPDs. The summation of SPDs can create even more diverse sources of light through combinations of these LED sources… (more)
