Abstract: A dual lamp fixture having an integral power supply and control circuit. The dual lamp fixture utilizes stroboscopic and incandescent lamps mounted near the focus of a parabolic reflector which may be actuated alternately, individually or simultaneously. Multiple lamps may be connected in parallel to a DC power bus and a differential line, twisted-pair communication bus to achieve a variety of controlled flashing patterns. Each lamp will perform its given tasks when an appropriate command signal is placed on the communication bus. To take full advantage of this distributed control and the advantages in bus-wiring topology, the power supply is located in close proximity to its controller and light fixture.
