RECESSED LED LIGHTING FIXTURE

摘要

A lighting fixture (10) for mounting onto or into a structure (12) facing an illumination area (14). The fixture (10) includes a support member (20) configured for mounting into the structure (12) and including a front end-portion (22) having an edge (24) defining a light opening (16) and a back end-portion (26) recessed from the opening (16). The support member (20) and opening (16) have a centerline (28). A mounting board (18) is disposed at the back end-portion (26) and defines with the support member (20) an open space (30) extending to the opening (16). An LED arrangement (40) includes (a) LED emitter(s) (42) on the mounting board (18) for directing light (46) toward the opening (16), each emitter (42) defining an emitter axis (44), and (b) a lens (50A) for each emitter (42) at least one of which is off-centerline in a first lateral direction (32). The lens (50A) is configured for distribution of emitter light in off-axial direction across the open space (30) and passing through the opening (16) at an edge portion (25) that is off-centerline in the opposite lateral direction (33), thereby to widen the illumination angle (48) from the fixture (10) while having no more than minimal light directed onto the support member (20).
