Definitions
- the present invention relates to a luminescent signage component suited for use in any type of signage, and having particular utility for indicating the position of an exit door in the case of an emergency, such as a fire.
- a luminescent signage component which includes a body having at least one cavity.
- Luminescent epoxy fills the at least one cavity.
- the luminescent epoxy in the cavity emits a luminescent glow in the event of a power failure.
- the at least one cavity defines a message conveying indicia, such as a series of alpha-numeric characters or a graphic symbol.
- luminescent epoxy fills the cavity in the body. This approach substantially increases the amount of luminescent material and, consequently, the time duration during which the luminescent material will continue to glow, as compared to the van Duynhoven patent reference.
- beneficial results may be obtained through use of the luminescent signage components, as described above, to this point the technology has not been able to supplant traditional backlit exit signs. Even more beneficial results may, therefore, be obtained when a portion of the body where the cavity or cavities are positioned is transparent. This enables the luminescent epoxy to be backlit by a light positioned behind the body. The backlit luminescent epoxy will be charged by the light positioned behind the body.
- beneficial results may be obtained through use of the luminescent signage components, as described above, when the cavity or cavities are recesses made in dark material, the dark material tends to absorb light and reduce the time it takes to charge the luminescent epoxy. Even more beneficial results may, therefore, be obtained when the cavities have a light reflecting coating to facilitate charging of the luminescent epoxy by a light positioned in front of the body. Beneficial results have been obtained through the use of a white paint.
- the body will take the form of a sign plate in most cases.
- the luminescent epoxy of the door molding will glow to assist the public in finding the exit door.
- the body take the form of a chair rail molding. In such a case, the luminescent epoxy of the chair rail molding will glow. If appropriate graphic indicia, such as arrows, were used; the glowing indicia on the chair rail molding could point the way to the exit door.
- beneficial results may be obtained through the use of the luminescent signage components, as described above, even more beneficial results may be obtained when the body is a transparent tubular body and the cavity is an axially extending bore filled with luminescent epoxy.
- FIGURE 1 is a detailed side elevation view, in section, of a luminescent signage component constructed in accordance with the teachings of the present invention, having a cavity in a transparent body portion.
- FIGURE 2a is a detailed side elevation in section of a luminescent signage component constructed in accordance with the teachings of the present invention, where the cavities are in dark material.
- FIGURE 2b is a front elevation view of the luminescent signage component illustrated in FIGURE 2a.
- FIGURE 3a is a detailed side elevation view, in section, of a luminescent signage component constructed in accordance with the teachings of the present invention, where the body is in the form of a molding.
- FIGURE 3b is a perspective view of the luminescent signage component as illustrated in FIGURE 3a where the moldings are in a public setting.
- FIGURE 4 labelled as PRIOR ART is a perspective view with partial cutaway of a traditional backlit exit sign.
- FIGURE 5 is a perspective view of an alternative tubular embodiment of luminescent signage component.
- a first embodiment of luminescent signage component, generally indicated by reference numeral 10 will be described with reference to
- FIGURE 1 A second embodiment of luminescent signage component, generally indicated by reference numeral 100 will be described with reference to FIGURES 2a and 2b.
- a third embodiment of luminescent signage component, generally indicated by reference numeral 200 will be described with reference to FIGURES 3a and 3b.
- a fourth embodiment of luminescent signage component, generally indicated by reference numeral 400 will be described with reference to
- a standard exit sign has an enclosure 12 with a light source 14. Radiant light 16 from light source 14 passes through translucent indicia 18 indicating to occupants the necessary information. Without backup power, when light source 14 fails, the sign fails.
- luminescent signage component 10 has a body 20 having a first face 22 and a second face 24.
- body 20 is in the form of a sign plate.
- a cavity 26, defining indicia, is formed out of body 20 on first face 22.
- Luminescent epoxy 28 fills cavity 26.
- Body 20 is adapted with a transparent portion 30 where cavity 26 is formed.
- a light source 14 is oriented within an enclosure 12 to shine on second face 24. Radiant light 16 from light source 14 shines through transparent portion 30 striking luminescent epoxy 28, charging and illuminating the indicia.
- luminescent signage component 10 Under normal conditions, light source 14 will be powered, illuminating the alpha-numeric characters on front face 22 that is defined by luminescent epoxy 28 within cavity 26.
- a key advantage of the preferred embodiment is that radiant light 16, by passing through transparent portion 30, also stimulates and charges luminescent epoxy 28.
- luminescent epoxy 28 continues to emit luminescent light 32, without the aid of backup power. Further, as there is substantially more luminescent epoxy within cavity 24, the effective life of luminescent light 32 is much longer, being a practical alternative to backup power.
- luminescent signage component 100 has a body 20 having a first face 22 and a second face 24.
- body 20 is in the form of a sign plate.
- Luminescent epoxy 28 fills cavity 26.
- Body 20 is adapted with a reflective coating 34 positioned at the base of cavity 26, behind luminescent epoxy 28.
- luminescent signage component 100 Under normal conditions, light source 14 will be powered, casting light on the indicia at front face 22 that is defined by luminescent epoxy 28 within cavity 26.
- a key advantage of the second preferred embodiment is that radiant light 16, by passing through luminescent epoxy 28, reflecting off reflective coating 34 and re-entering luminescent epoxy 28 not only brightens the indicia under normal conditions, but also stimulates and charges luminescent epoxy 28.
- luminescent epoxy 28 continues to emit luminescent light 32, without the aid of backup lighting. Further, as there is substantially more luminescent epoxy within cavity 24, the effective life of luminescent light 32 is much longer, being a practical alternative to backup lighting.
- luminescent signage component 200 has a body 20, first face 22, second face 24, cavity 26, luminescent epoxy 28 and reflective coating 34 as illustrated in FIGURE 2a and 2b.
- body 20 is in the form of a molding.
- a typical exit situation in a public place may have door moldings 38 and chair rail moldings 40.
- Each molding has a luminescent epoxy 28.
- a light source 14 provides radiant light 16 to illume and charge each indicia defined by each luminescent epoxy 28.
- luminescent signage component 200 Under normal conditions, light source 14 will be powered, casting light on the indicia at front face 22 that is defined by luminescent epoxy 28 within cavity 26. In the illustrated embodiment, in the event of a power failure, luminescent light 32 is emitted from luminescent epoxy 28, effectively and persistently directing patrons or other occupants to an exit.
- luminescent signage component 400 has a transparent tubular body 42 having a cavity 44 and an axially extending bore 46.
- Luminescent epoxy 28 is encapsulated by cavity 44 along axially extending bore 46, such that luminescent light 32 is emitted through transparent tubular body 42. Operation:
- transparent tubular body 42 is flexible, made out of a transparent PVC Vinyl. This allows transparent tubular body 42 to be formed into indicia. It will be appreciated that other Polycarbonate or Acrylic materials are available for use.
- luminescent epoxy 28 is injected into cavity 44, it can be charged with radiant light 16 from a light source 14. in the event of a power failure, luminescent light 32 is then emitted from luminescent epoxy 28 through transparent tubular body 42 displaying the desired indicia.
- the epoxy is composed of a resin and a hardener or activator.
- the luminescent material is composed of alkaline earth metal aluminum oxide doped with europium. Both the epoxy and the luminescent material are chemically and physically stable and environmentally friendly. The two materials combine to create a luminescent epoxy.
- the luminescent epoxy is used to fill the cavities in the selected body accordance with the first, second, third or fourth embodiment. The luminescent epoxy then hardens to become tough and durable, with the luminescent material suspended within the epoxy.
