Abstract: A recessed lighting unit for supporting an energizing lamp adapted to fit into an electrical socket using a housing. The electrical socket and lamp are mounted in the housing. The housing includes an opening for the passage of light from the lamp to the area to be illuminated. A source of power runs to the socket through a wireway. A heat protection mechanism interrupts the flow of electrical power to the lamp and socket upon the generation of excess heat in the vicinity of the housing. The heat protection mechanism is mounted immediately adjacent the housing in the wireway and forms a structural unit with the housing and a junction box.

Abstract: A portable light assembly conformed for excitation from the cigarette lighter outlet of an automobile comprises two light housings each universally pivoted from a central handle assembly. The central assembly includes opposed pivot fittings from which two laterally disposed swivel blocks are pivoted, each swivel block in turn pivotally supporting a corresponding light. In this form the alignment of each light may be individually selected to produce any desired beam pattern, the same pivotal freedom providing for a collapsed alignment where the lens portions of each light are protected from damage.

Abstract: A lighting fixture emits a beam covering in excess of 180.degree. by employing a reflector of parabolic cross-section and placing a linear light source perpendicular to the parabolic axis at or slightly forward of the parabola ends. A mounting plate containing the lamp socket and lamp ballast is connected to the reflector by means of a single screw to facilitate installation and maintenance. End members for the reflector include projecting collars which rotatably receive annular flanges from junction boxes through which power supply leads pass to connect to the lamp socket and pass through a raceway located behind the reflector to other fixtures mounted in tandem. The collar and flange can be secured together in any rotational position within a range of 360.degree.. A swivel form of junction box includes two members which are mutually rotatable about an axis perpendicular to the collar/flange axis to increase the positional adjustability of the fixture.

A first end (42) of a first arm (40) is nonrotatably connected axially with the second swivel member. A linear region (46) of the first arm extends rotatably through the axial passage of the third swivel member. The first and third swivel members are connected with the wall mounting by threaded sleeves (96, 102). In this manner, the second swivel member and the attached arm which extends axially therefrom are able to be rotated selectively around the wall mounting.

Abstract: Each one of a pair of swing units, for mounting the swing arm assemblies of a swing arm lamp, is formed as a relatively short substantially tubular member having a tubular mounting end of reduced outside diameter and that is provided with a circumferential groove. The reduced end of each swing unit is received by a respective mounting seat of a vertical swing bracket which mounts both swing units for rotation about a pair of predetermined axis of rotation that are spaced and parallel one to the other. A pair of threaded bolt like members are carried by the swing bracket so that an end of each threaded member can be moved from a position wherein the end projects into its respective groove, to prevent unseating of the swing unit from the bracket, but not so as to prevent rotation thereon; to a position wherein said ends are removed from the respective grooves so that the swing units can be removed from the bracket.

Abstract: This disclosure depicts a novel environmentally sealed and manually controlled swivel unit for use in an adjustable lighting fixture. The swivel unit comprises a base, a housing, a swivel ball device and a swivel ball controller. The swivel unit further comprises a tension means for forcing the swivel ball controller against the swivel ball device, and, in turn, for forcing the swivel ball device against a shoulder of the housing.

Abstract: A weatherproof terminal or junction box structure for a luminaire adapted for connection by a mast to a building or pole. The structure enables access to the terminal or junction box area for wiring and inspection without disassembly of the mounting of the luminaire to the mast and without the necessity of disassembling the luminaire itself. The mast telescopes within a channel receiver of the luminaire housing for mounting purposes. The mast is slotted at its entry end, the slot being encompassed within an access opening which may be covered by a wire way cover. Removal of the cover exposes the wiring for connection and inspection. With the cover in place, recessed within the receiver, the connection of mast to luminaire produces a weatherproof mounting. A second embodiment omits the need for the cover by normally setting the entry end slot rotated out of registration with the channel opening. Access to the slot may be had by rotating the luminaire about the axis of the channel receiver.
