A luminaire comprises a light guide having light outcoupling elements at one side and a flat light output surface at the other side, which is visible in use of the luminaire. An array of solid state lighting elements is arranged around the edge of the light guide facing the general light output direction. A respective reflector is associated with each solid state lighting element for reflecting light into the light guide. By providing the lighting elements all facing the general light output direction, they can be formed as a single unit, or as a small number of sub-units, thereby simplifying the manufacture. The design of the reflectors, the positioning of the lighting elements, and the design of the light outcoupling elements together may be used to create an asymmetrical light output beam shape. Actuation of different lighting elements may be used to provide different asymmetric light outputs.
