Abstract

In this paper the effect of typical outdoor LED lamps on star visibility index SVI was analyzed. For those lamps the spectral power distribution SPD, the nearest color temperature CCT [K] and efficacy n [lm/W] are provided. For given lamp, the SVI has been defined as ratio of its scotopic flux to scotopic flux created by full moon. The calculations shows that, the use of lamps with low CCT does not significantly affect the of the value SVI. Unfortunately from an economic point of view, those kind of lamps are less attractive in applications because of their low n.
