    摘要： Disclosed is a luminaire (1) comprising a sheet metal housing (100) shaped to include a trench (110) comprising a pair of opposing elongate side walls (111) extending from a trench floor; a pair of optical cavities (120) on opposite sides of the trench, each optical cavity being delimited by one of the elongate side walls (111) of the trench, a first inclining elongate surface portion (121) extending from an edge of the elongate side wall distal to the trench floor and a second inclining elongate surface portion (123) extending from the first inclining elongate surface portion, each optical cavity further comprising a diffuser (130) extending between the second inclining elongate surface portion and the elongate side wall; each optical cavity housing a plurality of solid state lighting elements (141) mounted on the first inclining elongate surface portion such that the solid state lighting elements face the diffuser; and at least one driver circuit (150) of said solid state lighting elements in said trench on the trench floor. A surface covering arrangement including such a luminaire is also disclosed.
