[57] ABSTRACT

A recessed lighting fixture or downlight is disclosed for mounting in a wide range of sloped ceilings. The recessed lighting fixture has a lamp adjustably coupled to a housing via an adjustable socket assembly having three degrees of movement for aiming the lamp in a particular direction, preferably perpendicular to the floor. The adjustable socket assembly has an upstanding bracket and a socket strap for aiming the lamp. In particular, the upstanding bracket has one end pivotally coupled to the trim collar of the housing for rotational movement of the lamp about a first pivot axis, and its other end pivotally coupled to the socket strap for rotational movement of the lamp about a second pivot axis. Also, the bracket and socket strap are coupled for linear movement of the lamp relative to the housing. In a preferred embodiment, the lighting fixture is provided with a reflector having baffles such that the lighting fixture has substantially the same appearance regardless of the slope of the ceiling.
