Technical Field

[0001] The invention mainly relates to the technical field of fluorescent strips, in particular to a novel long-acting aircraft cabin fluorescent strip. Background Art

[0002] Emergency lighting is the lighting provided when normal lighting is unavailable in the event of a survivable emergency. It provides the guidance required to leave the aircraft. Emergency lighting should be sufficient to allow passengers and crew members to enter and find emergency exits when leaving their seats, and then operate and use these exits. In the past, plug-in evacuation routes were used, which had the risk of short circuits or failure to provide power supply. Therefore, fluorescent strips were developed and installed on the cabin floor aisles. One is to provide lighting for the ground, and the other is to serve as a life-saving guidance sign to ensure that passengers can evacuate quickly in an emergency, thereby ensuring passenger safety.
