Abstract:
A luminaire housing (10) comprises a light chamber (15) at least partially delimited by a light-transmissive cover (30). The light chamber comprises a mounting region for mounting at least one solid state lighting element. The cover comprises at least one rounded corner section (31) in between two further sections (33), wherein the rounded corner section has an inner surface (311) having opposing inner endpoints (103, 105) and an outer surface (313) having opposing outer endpoints (113, 115). Each inner endpoint is positioned relative to the outer endpoint proximal to said inner endpoint such that no ray of light (301, 301') emitted by the at least one solid state lighting element entering the light-transmissive cover via an inner surface (331) of a further section exits the light-transmissive cover from the outer surface of a curved corner section. A luminaire including such a luminaire housing, a design method and a manufacturing method for such a luminaire housing are also disclosed.
