Abstract: An extendable and/or retractable illuminating device comprises a luminaire atop a telescoping mast, which is selectively positionable between extended and retracted positions, suitable for use as a warning signal. The luminaire has a strobe feature and its intensity is capable of automatic adjustment in response to ambient light levels. The telescoping mast, and thus the luminaire, are driven by an electric motor within a manually portable case, which also houses a rechargeable electrical power supply and microcontroller unit for providing power and operating commands to the luminaire.

Abstract: The extendable strobe light device (1) comprises a telescoping light mount (10) bearing a strobe light (11). By manual operation or by power to an antenna drive motor (23) the telescoping light mount (10) is extended or retracted. An insulated electrical conductor (28) provides power to the strobe light (11). The insulated electrical conductor (28) is wound on a negator reel (46). A negator spring reel assembly (32) contains a negator spring (400) retracts the insulated electrical conductor (28) when the telescoping light mount (10) is retracted. An electrical brush assembly (43) comprises a brush assembly insulated housing (52) composed of a rigid material including metals and plastics. The brush assembly insulated housing (52) is affixed to the case by screws or bolts (34).
