LUMINOUS FLUX
Definition
A <LUMINOUS FLUX> is a <Property> that is the quantity of an <ENERGY> of the light emitted per second in all directions calculated as Phi_v = K_m.integral[0, infinity](Phi_lambda(lambda) .V(lambda) d.lambda where K_m is the maximum spectral luminous efficacy, Phi_lambda(lambda) is the spectral radiant flux, V(lambda) is the spectral <LUMINOUS EFFICIENCY> and lambda is the wavelength
