ABSTRACT:
An emergency information lighting system (100/200/300), comprising a primary light source (110/210/310) and a housing (112/212/312) for the primary light source (110/210). The housing (112/212/312) includes a first wall (120/220/320) with indicia openings (126/226/326) which correspond to emergency information. The primary light source (110/210/310) emits primary light, which passes through the indica openings (126/226/326) to display the emergency information to a viewing environment. The housing (112/212) or a bulb (316) incorporates a phosphorescent material (132/232/332) which, in the absence of the primary light, emits passive light to display the emergency information to the viewing environment.
