1. A luminaire comprising a housing with a base having a first carrier surface on which a plurality of LED Modules is arranged, and opposite to said first carrier surface a cover arranged in a light exit window of the luminaire,
wherein each LED Module is a curved LED Module comprising a curved PCB having a main surface on which a number of N LEDs are mounted, wherein the LEDs are facing towards the light exit window and are screened by said cover,
wherein the LED Modules are arranged as to comprise an inner arrangement of LED Modules surrounded by a concentric outer arrangement of LED Modules, and
wherein all LED Modules are identical,
wherein the light exit window is circular with a diameter Dl and comprises a plurality of evenly arranged curved LED Modules at said first carrier surface, a portion of said plurality of LED Modules are arranged as the outer arrangement to form a circle configuration with a diameter Dc around the central, inner arrangement of at least two LED Modules, wherein the outer arrangement includes a greater number of LED Modules than the inner arrangement, and wherein a ratio of DI:Dc is 1.2<=Dl/Dc<=1.6 to provide a uniform appearance of light in the light exit window of the luminaire.
