Luminous coefficientThe luminous coefficient is a coefficient that measures the integrated fraction of the radiant power that contributes to its luminous properties as evaluated by means of the standard luminosity function. The luminosity coefficient is:
yλ is the standard luminosity function Jλ is the spectral power distribuiton of the radiant intensity The luminous coefficient is unity for a narrow band of wavelengths at 555 nanometres.
