TīmeklisIf the lamp emits all radiation at 555 nm (where V λ = 1), the luminous efficacy will be of about 680 lm W −1, the theoretical maximum value.The lamp efficacy will be 26 and 73 lm W −1, when the whole light is emitted at 450 and 650 nm respectively. The luminous coefficient is luminous efficiency expressed as a value between zero and … TīmeklisThe luminaire maintenance factor LMF takes into account the reduction of luminous flux due to the soiling of the luminaire. It signifies the ratio of a luminaire’s light output ratios before and after cleaning. The LMF depends on the version of the luminaire and the related possibility of soiling.
