摘要:
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).
