Abstract:
A modular rotatable warning light assembly comprising:a cylindrical shaft having an axis, a first outside diameter and an open first end including a plurality of axially projecting tabs separated by a plurality of slots, said first end including an outward facing circumferential groove, said groove being orthogonal to said axis and traversing at least two of said tabs; a reflector support subassembly comprising a reflector mount and a hub, said reflector mount surrounding said hub and supported for rotation about said hub by two axially spaced bearings disposed between an inward facing surface of said reflector mount and an outward facing surface of said hub, said reflector mount including an outward facing circumferential gear wheel and said hub having an inward facing cylindrical surface having a second diameter substantially equal to said first diameter; a motor including a shaft; a worm gear mountable to said shaft, said worm gear configured to mesh with said gear wheel; a plurality of differently configured lamp holders, each lamp holder having a base including a plurality of radially projecting legs complementary to said slots, an axial passage for electrical conductors and socket means for receiving a lamp; a plurality of differently configured lamps, each lamp complementary to at least one socket means; a plurality of differently configured reflectors, each reflector having a reflecting surface and fixable to said reflector mount; a plurality of differently configured base plates, each base plate including an aperture for securing said shaft, a bracket for supporting said motor and means for fixing said base plate to a support structure; wherein said shaft is secured to a base plate selected from said plurality of differently configured base plates, said hub is disposed around said shaft so that said reflector mount is supported for rotation about said shaft, said motor is mounted to the bracket of said selected base plate, said worm gear is mounted to said shaft and meshed with said gear wheel so that rotation of said shaft imparts rotational motion to said reflector mount, a lamp holder selected from said plurality of differently configured lamp holders is axially inserted into said shaft so that at least one of said legs fits within at least one of said slots, said lamp holder being secured to said shaft, a lamp selected from said plurality differently configured of lamps is installed in the socket of said lamp holder and a reflector selected from said plurality of differently configured reflectors is fixed to said reflector mount for rotation therewith.
