Abstract: A roadway luminaire generally includes a housing and a door pivotably connected to the housing. The housing includes a rear wall having an opening sized and shaped to receive a mounting arm for mounting the luminaire thereto, a top wall extending from the rear wall and an arm receiving channel formed in the top wall adjacent the rear wall for receiving an end of the mounting arm. The channel is formed with a step arrangement having a plurality of steps ascending in order along a length of the channel. The steps permit angular mounting adjustment of the housing with respect to the mounting arm depending on which step the end of the mounting arm rests.

Abstract: A receptacle assembly for a twist-lock photocontrol that is mounted on a luminaire housing. The assembly includes a receptacle and a spring clamp. The receptacle has a disc portion with a hub extending from the central portion of the back side, a perimeter side wall with a castellated bottom edge that engages stops on the luminaire housing. Three fingers extend from the back side of the disc and terminate at a lip edge. The spring clamp has a substantially flat, ring-shaped body that includes a top surface, an opening, an inner edge, an outer edge, and at least one pair of spring members. The receptacle is attached to a luminaire housing using the spring clamp. The orientation of the receptacle can be adjusted and can be locked into a stationary position without tools.
