A method for illuminating explosive, flammable, and other hazardous environments. The method employs electroluminescent lights heaving controlled dielectric strength and capacitance, which when matched with the low current and voltage from an intrinsically safe power supply, and the controlled capacitance of each lighting circuit, produces an emergency lighting system which is both safe and effective.

Method of illuminating and providing emergency egress guidance for

A structure for providing electromagnetic wave energy primarily in the near infra-red region of the spectrum and having an electroluminescent lamp element which includes a red fluorescent dye material for emitting energy in both the visible and the near infra-red regions of the spectrum, and at least one layer of optical filter material having selected color filter characteristics for transmitting electromagnetic wave energy therefrom in a manner such that the amount of energy transmitted in the near infra-red region is substantially increased and the amount of energy transmitted in the visible region is substantially decreased.
