blue light hazard factor of luminous radiation

αB,v

quotient of blue light hazard weighted radiant flux and the V(λ) weighted radiant flux

where λ is wavelength, Φe,λ(λ) is spectral radiant flux, B(λ) is the blue light hazard spectral weighting function, and V(λ) is the CIE spectral luminous efficiency function for photopic vision

Note 1 to entry: Luminous radiation refers to optical radiation weighted with the CIE spectral luminous efficiency function for photopic vision, V(λ).

Note 2 to entry: The use of this term is only reasonable if parts of the optical radiation are in the visible range and thus .

Note 3 to entry: The blue light hazard factor of luminous radiation has unit one.
