Abstract: A luminaire especially adapted for use as an outdoor framing projector is weatherproof and has an optical system for projecting a beam of a variable size and focus. A housing made in extruded sections has a longitudinally continuous sealed joint between the sections formed by a dog-leg shaped lip on one adjacent section fitting into a correspondingly shaped recess on the other section, with a resilient sealing strip compressed between the lip and recess and a detent holding the lip and recess together. A fan forced interior air recirculation cooling system cools a lamp with the warmed air flowing longitudinally back to front past top and side walls of the housing provided with cooling fins and a return air duct adjacent to the bottom wall drawing air from the front of the housing back to the inlet of the fan.

Abstract: A cantilevered electrical light fixture (10) has a power supply line (30) running through it from a mounted end (17) to an internal connection zone (36) at a cantilevered end (18). A cover (52) closes the internal connection zone (36) and mounts a plug-half (40) and a switch (42), which are electrically connected to the power supply line (30). A light head (16) mounted to the cantilevered end (18) by a post (76) with a non-circular portion (78) and a threaded shank (80) has lamp wiring (110) connected to a plug-half (120) which releasably mates with the plug-half (40) mounted to the arm (12). A U-shaped bracket (116) mounts a socket (114) to a shell (84) of the light head (16) to bias the lamp bulb (154) against the shell (84).

Abstract: A control system for positioning a searchlight (2) in azimuth and elevation including an upper torque tube (34) and a lower torque tube (39) which are coupled together; an upper push rod (46), push rod coupling (50) and lower push rod (54) which are coupled together; and control elements (65, 90 & 93, 100) operative to rotate the lower torque tube and also operative to reciprocate the lower push rod.

Abstract: An electrical light fixture (1) having a tubular arm (2) with an opening (20) formed in a wall portion to define a connecting zone (21) in which internal lamp wiring (13) is connected to an external power supply line (25) which extends through a cover (23) for the opening.

Abstract: An electrical light fixture comprising a housing (12), a lamp assembly (11) within the housing, and a protective cage (13) surrounding the housing. The protective cage can be formed with a pair of cage elements (14, 15) joined together, and the lamp assembly can have a slip-fit engagement with the housing through an open end thereof.

Abstract: A wide beam floodlight fixture by which the light from a lamp bulb that radiates light in all directions away from its axis, directs that light in a wide well defined beam. The fixture comprises a housing with a transparent front wall, and opposite opaque top, bottom and side walls. A curved reflector in the rear of the fixture housing embraces the lamp bulb and directs its light out of the transparent front wall. The top and bottom walls of the fixture have aligned access ports through either of which the lamp bulb may be removed and replaced. A socket housing removably attached to the bottom wall of the fixture housing closes the bottom access port and has the socket for the lamp bulb base shock-resistantly mounted therein. The access port in the top wall of the fixture housing is closed by a removable cover, from the underside of which a flanged ring is resiliently supported to embrace the upper end portion of the lamp bulb.
