BACKGROUND OF THE INVENTION1. Field of the Invention
The present disclosure relates to illuminated signage systems, and more particularly to illuminated signage systems having etched non-opaque materials for refracting light and/or electroluminescent wire.
2. Description of Related Art
Presentation of important information, such as advertisements, directions, or decorative art often relies on non-illuminated displays which can be difficult to read or view in low-light situations or can be visually overpowered by surrounding displays of a similar type or by busy backgrounds that tend to camouflage the intended message. To combat these and other problems, illuminated signage systems have been developed.
Some examples of illuminated signage systems include neon lighting, traditional backlit signs, and front-lit signs. Still others have conceived of using etched non-opaque materials which are lit from an edge to refract light at strategic points to develop an image. Further, some have used electroluminescent (EL) wire to create images on a surface. The current state of the art has several shortcomings. First, in signs using EL wire, the displays are difficult to make portable and often rely on a formation of the EL wire that causes lines to be continuous, adding visual clutter to a display. The current EL wire signs also suffer from structural qualities that make them difficult to manufacture and therefore, more expensive. In signs using etched non-opaque materials, the prior art does not account for a desire to change background images easily. Alternatively, the prior art does not provide an easily manufactured edge-lit sign having a printed layer showing through the non-opaque material to present a display in conjunction with an etched portion of the non-opaque material. In prior art signs using etched non-opaque materials or EL wire, the finished products are not very portable for some applications, such as roadside handheld spinning by advertisers, or for use as a cheer display in a cheerleading squad or by fans of a sport or event.
So as to reduce the complexity and length of the Detailed Specification, and to fully establish the state of the art in certain areas of technology, Applicant(s) herein expressly incorporate(s) by reference all of the following materials identified in each numbered paragraph below.
U.S. Pat. No. 3,052,812 discloses a flexible electroluminescent strand. The strand comprises two conductors separated by an electroluminescent phosphor. A varying voltage applied across the two conductors excites the phosphor so that it produces light.
U.S. Patent Application Publication 2010/0123385 teaches electroluminescent fibers that include two electrical conductors embedded in a matrix of a polymer having phosphor particles, which are excited to emit light when electrical power is applied to the conductors. The fibers are meant to be flexible, washable, and able to be integrated into fabrics using textile equipment.
U.S. Patent Application Publication 2008/0036375 and U.S. Pat. Nos. 3,069,579 and 7,737,633 disclose alternative electroluminescent wires.
U.S. Patent Application Publication 2006/0042137 discloses glowing signs formed from electroluminescent wire which is bent into shapes. To create gaps in the lit electroluminescent wire patterns, a dark paint or other suitable material is used to cover the wire and block its light in the appropriate areas.
U.S. Pat. No. 7,048,400 discloses illuminated systems capable of use as an advertising medium.
The invention may use energy from a solar photocell to power a light emitting device, which could be a film-like component printed onto a substrate. The EL device is formed from layering the components of the EL device onto a substrate.
U.S. Pat. No. 4,999,936 discloses an illuminated sign that uses an electroluminescent panel covered by a stencil with an image cut out to allow the desired light pattern to project through to convey the image.
U.S. Pat. Nos. 6,203,391 and 6,965,196 disclose electroluminescent signs having lighted portions made by screen printing the layers of the electroluminescent lamp onto the sign, with an illuminating phosphor layer being printed in the shape of the desired image.
U.S. Patent Application Publication 2007/0210992 discloses an EL wire display having an array of pegs that can accommodate individual segments of EL wire routed around the display in a desired pattern. This display is disclosed as self-contained and portable.
U.S. Pat. No. 5,276,591 discloses an edge-lit translucent panel for even illumination of the entire surface of the panel, which has a graphic applied by painting, silk screening, or etching. The etching reflects light from within the panel, and in another embodiment, painted graphics in optical contact with the surface of the panel are illuminated by the light from within the panel.
U.S. Pat. Nos. 6,481,131 and 7,681,347 are examples of edge-lit translucent panels with an etched or inscribed design such that light entering from the side of the panel strikes the etching to be reflected outwardly to a viewer.
U.S. Pat. No. 5,433,024 discloses an edge-lit display comprising a tapered transparent plate with a piece of advertising applied to a surface of the plate. Lamps at the edge of the tapered plate provide light into the plate, whereby the tapered nature of the plate causes light to reflect within the plate and provide illumination for the advertising.
U.S. Pat. No. 6,705,033 discloses an edge-lit sign having an acrylic sheet which is etched around fluorescent letters applied to the acrylic sheet, such that light transmitted into the acrylic sheet is refracted to exit the etched area to illuminate the boundary of the fluorescent letters.
U.S. Pat. No. 6,076,294 discloses an illuminated sign having a photoconductive plate which is inset from a back face of the plate to define indicia. Except for the areas defined by the indicia, the photoconductive plate is covered by an opaque material opposite the front viewing side. The areas defined by the indicia are covered by a fluorescent material opposite the front viewing side. The plate is lit from an edge such that the light impinges on the boundaries of the indicia to cause the indicia to illuminate in low-light conditions, while the fluorescent material renders the indicia visible during daylight hours.
Applicant(s) believe(s) that the material incorporated above is “non-essential” in accordance with 37 CFR 1.57, because it is referred to for purposes of indicating the background of the invention or illustrating the state of the art. However, if the Examiner believes that any of the above-incorporated material constitutes “essential material” within the meaning of 37 CFR 1.57(c)(1)-(3), applicant(s) will amend the specification to expressly recite the essential material that is incorporated by reference as allowed by the applicable rules.

Aspects and applications of the invention presented here are described below in the drawings and detailed description of the invention. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventors are fully aware that they can be their own lexicographers if desired. The inventors expressly elect, as their own lexicographers, to use only the plain and ordinary meaning of terms in the specification and claims unless they clearly state otherwise and then further, expressly set forth the “special” definition of that term and explain how it differs from the plain and ordinary meaning Absent such clear statements of intent to apply a “special” definition, it is the inventors' intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.
The inventors are also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.
Further, the inventors are fully informed of the standards and application of the special provisions of 35 U.S.C. §112, ¶ 6. Thus, the use of the words “function,” “means” or “step” in the Detailed Description or Description of the Drawings or claims is not intended to somehow indicate a desire to invoke the special provisions of 35 U.S.C. §112, ¶ 6, to define the invention. To the contrary, if the provisions of 35 U.S.C. §112, ¶ 6 are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for, and will also recite the word “function” (i.e., will state “means for performing the function of [insert function]”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for performing the function of . . . ” or “step for performing the function of . . . ,” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventors not to invoke the provisions of 35 U.S.C. §112, ¶ 6. Moreover, even if the provisions of 35 U.S.C. §112, ¶ 6 are invoked to define the claimed inventions, it is intended that the inventions not be limited only to the specific structure, material or acts that are described in the preferred embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.
A more complete understanding of the present invention may be derived by referring to the detailed description when considered in connection with the following illustrative figures. In the figures, like reference numbers refer to like elements or acts throughout the figures.
Elements and acts in the figures are illustrated for simplicity and have not necessarily been rendered according to any particular sequence or embodiment.
DETAILED DESCRIPTION OF THE INVENTIONIn the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed inventions may be applied. The full scope of the inventions is not limited to the examples that are described below.
The present invention provides among other things outdoor media signage products that allow for a message or advertisement to be displayed both day and night. Daytime viewing may be accomplished through the use of full color printed graphics which display a message or advertisement in a well lit environment, much like traditional signage. However, as lighting in the environment diminishes, the sign is able to be “switched on” in which an embedded electroluminescent wire, sheet, or ribbon lighting becomes apparent. Alternatively, an etched non-opaque material may be lit from an edge. The switching on of the invention can be accomplished by a standard electrical switch, a photovoltaic sensor to sense when lighting conditions are dim enough to justify activating the sign lighting, or other switching mechanism known to one of ordinary skill in the art. The lighting used in the invention, including electroluminescent elements and light emitting diodes, are very efficient and therefore it is possible to run these signs on portable power sources such as traditional batteries, rechargeable battery sources, and even solar power cells. This allows for the signage to be illuminated while remaining stationary or fully portable, such as for use in a handheld roadside spinning advertisement often used to attract customers in a dynamic way, or for use as a cheer or motivational tool.
In some embodiments of the invention, a sign may have a solar cell for sunlight to be gathered during the daytime advertising hours to charge one or more rechargeable batteries acting as the power source for the sign when it is switched on later, either manually or automatically with the use of a photovoltaic sensor. Alternatively, some embodiments may use standard store-bought batteries. In yet another embodiment, a sign may use a transformer powered by a standard 120v electrical socket.
Because of the rechargeable and solar features or battery powered features, the applications of this invention are widespread. The primary use of these signs may be to showcase sponsor, business, client, or promotional messages or advertisements in a way that attracts attention to either purchase, attract potential clients, entertain, or inform in various lighting conditions. The use of such signage, however, would be understood by those having ordinary skill in the art as not being limited as such.
Electroluminescent Element Signage:
In one application of the invention, and as shown below in
In some applications of the invention, the printed surface 120 displays the message or graphic during the times when lighting is not necessary due to the sun or other forms of external light sources. Graphics are typically provided by the individual requesting that a sign be made or they may be created in-house. The graphics may be printed using a large format printer onto the printed surface 120.
A typical non-cursive word or shape requires that there be spacing between the presented letters or shapes. In some embodiments of this invention, an illuminated non-cursive word or shape may be created using a single strand of EL Element. In order to give the appearance that each of the characters is separate, the signage may incorporate a weaving or routing technique. Channels 145 are cut into the printed surface 120 and the substrate layer 130 to allow the EL Element 140 to be guided through desired areas of the sign. The EL Element 140 is laid into the assembly 155 comprised of the printed surface 120, the substrate layer 130, and the adhesive sheet 150. The EL Element 140 is bent and formed through the channels 145 to create a border of the desired letter or shape. When the letter or shape is outlined with the EL Element 140 and a discontinuity in the image is desired, the EL Element 140 is pushed beneath the printed surface 120, through the substrate layer 130 and, if necessary or desired, through the adhesive sheet 150, and then brought back through to the printed surface 120 to the next of the channels 145. Alternative embodiments using thicker substrate layers 130 may not require that the EL Element 140 go all the way through the substrate layer 130, as in those embodiments the thicker substrate may accommodate the routing of the EL Element 140 without the need for penetrating the adhesive sheet 150. This weaving process allows for the letters and/or shapes to appear as individual characters rather than appearing connected to each other. If the substrate layer 130 is not sufficiently thick to accommodate the EL Element 140 without penetrating the adhesive sheet 150, there may be a need for clearance space 175 between the substrate layer 130 and rigid backing substrate 180. This may be created with the spacing layer 170, which may be of a frame configuration or other configuration with internal clearance space 175 to accommodate the EL Element 140. Having the EL Element 140 woven behind the printed surface 120 results in a viewer only observing desired lit areas. To ensure that cut pieces of the printed surface 120 and substrate layer 130 remain in place, the adhesive sheet 150 may be used. The width of channels 145 is respective to the dimensions of the EL Element 140 that will be used as the border lighting or inlay lighting.
Referring in part to
In other embodiments, a lighting effect can be produced by incorporating an electroluminescent sheet or ribbon directly behind the cut printed surface 120. In these embodiments, entire letters or images on the sign can be illuminated, or backlighting can be provided for photographic transparencies.
Referring now to
In a wire or tubular form, the EL Element 140 includes a solid copper wire core 310 coated in phosphor 320. A fine copper wire 330 is wound around the coated core 310 in a helical or spiral pattern. The fine wire 330 is electrically isolated from the copper core. On the outside of the copper core, phosphor, and fine wire is a clear protective sleeve 340. A clear or colored outer sleeve 350 surrounds sleeve 340. An electric potential from a resonant oscillator 360 of approximately 90-120 volts at about 1000 Hz is applied between the copper core wire 310 and the fine wire 330, however, one of ordinary skill in the art would recognize that any appropriate voltage or frequency may also be used. The EL Element 140 can be modeled as a coaxial capacitor with about 1 nF of capacitance per foot, however this disclosure is not intended to be limited to such a capacitance. The rapid charging and discharging of this capacitor excites the phosphor to emit light. The colors of light that can be produced efficiently by phosphors are limited, so many types of wire may use an additional fluorescent organic dye in the sleeve 350 to produce the final result. These organic dyes produce colors like red and purple when combined with the bluegreen light of the wire-wrapped, phosphor covered core 310, 320, 330. A resonant oscillator 360 is typically used to generate the high voltage drive signal. Because of the capacitance load of the EL Element 140, using an inductive (coiled) transformer makes the driver a tuned LC oscillator; therefore it is very efficient. The efficiency of the EL Element 140 is very high, so a few hundred feet of EL wire can be powered by AA batteries for several hours.
In some embodiments of the invention, the EL Element 140 receives its power through the use of an inverter which converts standard voltage produced from store bought batteries, rechargeable batteries, and from solar cells into the correct frequency required to power the EL Element 140. The use of a single inverter allows for multiple color strands of EL elements to be used, allowing for full customization in a sign. In one embodiment, the inverter may include a sequencer effect which allows specific portions of the signage to light up at different times to provide a unique eye-catching effect.

A printed layer in the form of printed sheet 440 may be coupled behind the non-opaque material 410 to display a message or graphic during the times when lighting is not necessary due to sun or other forms of external light sources, or during times when the edge lighting is powered to provide a combined image effect. The printed sheet 440 may be adhered to the non-opaque material 410 or a sign assembly 400 can be made by layering the etched non-opaque material 410, the printed backing or sheet 440, and a rigid backing substrate 180, all held together with stand-off screws, corner protectors 190 in
