Abstract

An emergency light system which incorporates flashing strobe type of lights located along the aisle(s) of an aircraft, or other passenger carrier, would provide flashing arrows indicating the location of emergency exits. The sequential firing of the flashing lamps will further create the effect of a moving light beam to lead passengers toward the exit area(s). Also, with programmable control means, there can be stroboscopic type flashing lights to direct egress to only those exits which are open.

Claims

1. An emergency stroboscopic type of lighting system for directing passengers to an appropriate exit of a large passenger carrier having a plurality of doors, one or more of which may be unopenable in an emergency situation, which comprises in combination,

a. a strobe system including a plurality of electronic flash lamps which are maintained in spaced positions along the length of the passenger area of the carrier;

b. battery power supply means and high voltage-capacitive-trigger discharge means for each of the electronic flash lamps of the system;

c. an output driver means with switching means to connect to said flash discharge means for operating said flash lamps;

d. a time-base generator means connecting to a logic controller means and the latter in turn connecting to said output driver means to provide for the timing and switching thereof and the sequential firing of said plurality of electronic flash lamps in a manner whereby such sequential firing will create the effect of a moving light beam that will indicate a direction of egress from said carrier; and

e. a switch means at each door of the plurality thereof, each such switch being interconnected with said controller means, said controller means including programming means to provide a controlled sequence of firing from the driver means such that resulting lamp flashings will indicate directions to only such doors that are available for egress.

2. The lighting system of claim 1 further characterized in that each electronic flash lamp of the strobe system has high voltage-discharge means and battery power source maintained closely adjacent the zone of the flash lamp.

3. The lighting system of claim 1 further characterized in that the electronic flash lamps are positioned along each overhead luggage or hat rack area extending along the aisles of the carrier.

4. The lighting system of claim 1 further characterized in that the electronic flash lamps are housed within seat armrests along the aisle(s) of the carrier.
