Definitions

  • the invention is based on the problem, transparent luminaire covers - whether clear-transparent or in combination with a structuring - to be designed so that an optimal, glare-free light scattering is achieved without affecting the luminous efficacy.
  • This problem is solved with the features of claim 1.
  • the luminaire cover has at least on the outer surface in the area above the light source, one or more convex elevations which, with the luminaire assembled and switched on, ensure that the light rays from the underlying light source (s) are distributed evenly and without glare, without limiting the luminous efficacy.
