Definitions
- This invention relates generally, as indicated, to an emergency informational lighting system and, more particularly, to a lighting system wherein emergency information is displayed by either primary light or a phosphorescent passive light in the absence of primary light.
- a common emergency information lighting system comprises a primary light source and a housing for the primary light source.
- the primary light source has electrically powered lighting components (e.g., filaments, transformer ballast, etc.) and an envelope (i.e., a "bulb") that surrounds these lighting components.
- the housing typically comprises a series of walls, and a front wall includes indica openings which correspond to emergency information. For example, the openings can spell out the word "EXIT" or show an arrow pointing in an appropriate escape direction.
- a business office, factory, school, or other public building can have dozens and sometimes even hundreds of such emergency information lighting systems.
- the primary light source When the primary light source is illuminated, the primary light shines through the indicia openings, thereby displaying the emergency information. However, when the primary light source is not illuminated because its power supply is interrupted, the information will not be visible. In this situation, supplemental power can be provided via a battery or secondary electric source (e.g. , an on-premise emergency generator) so that the emergency information will remain visible during emergency conditions.
- a battery or secondary electric source e.g. , an on-premise emergency generator
- the present invention provides an emergency information lighting system, wherein components of a conventional system (e.g., housing walls or a bulb envelope) incorporate a phosphorescent material so that emergency information remains visible during emergency conditions. More particularly, the present invention provides an emergency information lighting system comprising a primary light source and a housing for the primary light source.
- the housing includes a first wall with indicia openings which correspond to the emergency information.
- the primary light source emits primary light, which passes through the indica openings to display the emergency information to a viewing environment.
- the housing can incorporate a phosphorescent material which, in the absence of the primary light, emits passive light to display the emergency information to the viewing environment.
- the front wall of the housing can incorporate the phosphorescent material
- rear/side walls of the housing can incorporate the phosphorescent material.
- the phosphorescent particles can be coated on the exterior surface of the front wall or can be coated on the interior surface(s) of the rear/side wall(s) or, instead, phosphorescent particles can be embedded within the molded polymer of the walls.
- the envelope (i.e., the "bulb") for the primary light source can incorporate a phosphorescent material which, in the absence of the primary light, emits passive lightto display the emergency information to the viewing environment.
- phosphorescent particles can be coated on the bulb or embedded therein.

- the primary light source 110 comprises lighting components 114 that are electrically powered.
- the primary light source 110 is an incandescent light bulb
- the electrical components 114 can comprise a filament electrically connected to the power source.
- the lighting system 110 includes a fluorescent light bulb
- the electrical components 114 can comprise a transformer ballast electrically connected to the power source and a fluorescent tube wrapped around the transformer.
- the primary light source 110 additionally comprises a glass or plastic envelope 116 (i.e., a "bulb") that surrounds the lighting components 114.
- the housing 112 comprises a front wall 120, a rear wall 122, and side walls
- the front wall 120 includes indica openings 126 which correspond to emergency information which, in the illustrated embodiment, is the word "EXIT.”
- emergency information could include, for example, an arrow pointing in an appropriate escape direction.
- the front wall 120 of the housing 112 incorporates a phosphorescent material 132 which absorbs and stores light radiated thereupon and, in the absence of ambient or artificial light, will emit phosphorescence to provide passive lighting.
- the phosphorescent particles 132 can be coated on the exterior surface 128 of the wall 120 as shown in Figure 1C.
- the phosphorescent particles 132 can be embedded within the wall 120 as shown in Figure 1 D.
- the particles 132 could be introduced into the to-be-molded composition (e.g., a polymer) prior to molding, curing, and/or setting.
- the primary light source 110 will emit primary light, which passes through the indica openings 126 to display the emergency information to a viewing environment.
- the indicia openings 126 will be illuminated and the surrounding front wall 120 will be dark, as shown in Figure 1 E.
- the lighting system 200 includes a primary light source 210 (with lighting components 214 and an envelope 216) and a housing 212 (with walls 220, 222, and 224) for the primary light source 210.
- the front wall 220 includes indica openings 226 which correspond to emergency information.
- the side wall 224 and/or the rear wall 226 of the housing 212 incorporate a phosphorescent material 232 which absorbs and stores light radiated thereupon and, in the absence of ambient or artificial light, will emit phosphorescence to provide passive lighting.
- the phosphorescent particles 232 can be coated on the interior surface 230 of the wall 222/224 as shown in Figure 2C, or embedded within the wall 222/224 as shown in Figure 2D.
- the primary light source 210 will emit primary light, which passes through the indica openings 226 to display the emergency information to a viewing environment.
- the lighting system 300 includes a primary light source 310 (with lighting components 314 and an envelope 316) and a housing 312 (with walls 320, 323, and 324) for the primary light source 310.
- the front wall 320 includes indica openings 326 which correspond to emergency information.
- the envelope 316 (e.g., bulb) incorporates a phosphorescent material 332 which absorbs and stores light radiated thereupon and, in the absence of ambient or artificial light, will emit phosphorescence to provide passive lighting.
- the phosphorescent particles 332 can be coated on the surface of the envelope 316 as shown in Figure 3C, or embedded with the envelope 316 as shown in Figure 3D.
- the coating and/or embedding can encompass the entire surface area of the envelope 316 ( Figure 3G) or can be concentrated in the areas offset from the emission direction of the primary light ( Figure 3H).
- the primary light source 310 will emit primary light, which passes through the indica openings 326 to display the emergency information to a viewing environment.
- the phosphorescent material 332 In the absence of the primary light, and in dark conditions, the phosphorescent material 332 emits passive light to display the emergency information to the viewing environment. (Figure 3F.) In either case, the indicia openings 326 will be illuminated and the surrounding front wall 320 will be dark.
- the phosphorescent material 132/232/332 can be chosen to provide an emission of at least 15.0 mcd/m 2 at ten minutes and at least 2 mcd/m 2 at sixty minutes and/or an emission of at least 20.0 mcd/m 2 at ten minutes and at least 2.8 mcd/m 2 at sixty minutes.

These phosphorescent phosphors show excellent photo- resistance and possess extremely long afterglow characteristics.
- the phosphorescent material 132/232/332 should be such that an acceptable optical transmittance is provided so that primary light from the primary light source 310 can be transmitted through the envelope 316 to the viewing environment.
- the coated and/or embedded bulb 316 could have an optical transmittance of at least 50%,, at least 60%, at least 70%, at least 80%, and/or at least 90%.
- a low density can be used when coating the envelope 316 and/or when incorporating the phosphors therein.
- This low density corresponds to a high transmission, whereby high (or at least acceptable) emissions are accomplished without overly compromising transmission.
- components of a conventional system e.g., housing walls 120/222/224 or a bulb envelope 316
- a phosphorescent material 132/232/332 so that emergency information remains visible during emergency conditions.
