An illuminated display that is susceptible to interruption or termination of active lighting capability and provides passive lighting capability in such circumstances. The illuminated display features an active illumination source providing active lighting capability and a display member (i) arranged in light-receiving relationship to the active illumination source and (ii) containing photoluminescent pigment incorporated therein in sufficient amount and distribution to illuminate the display during the interruption or termination of active lighting capability, to provide passive lighting capability. The illuminated display may further include a fluorescent pigment arranged in photoluminescent light-receiving relationship to the display member containing the photoluminescent pigment, whereby the fluorescent pigment down-converts photoluminescent light from the display member during the interruption or termination of active lighting capability.

Fail-safe illuminated display comprising multimodal illumination components

An emergency egress system for a locus that is exposed to light in non-emergency use and susceptible to interruption or termination of light in emergency circumstances. The emergency egress system comprises a fibrous web deployed in the locus, wherein the fibrous web has photoluminescent fiber incorporated therein in sufficient amount and distribution to illuminate the web or predetermined portions thereof during the interruption or termination of light in emergency circumstances, and subsequent to light exposure thereof.

Photoluminescent emergency egress pathway marking system

An electroluminescent lamp having an indexing indicium, e.g., a registration mark, located within the lit surface area of the lamp, with the registration mark preferably being transparent to the illumination generated by the lamp when the lamp is lit in use, but being readily detected when selectively activated for providing an alignment point or region on the lamp, such as by activation with ultraviolet light of specific frequency/wavelength characteristics, when the registration mark is formed by deposition on the lamp lit surface of a dot or blob of a composition containing an ultraviolet radiation-fluorescent printing ink.
