Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This present invention relates to a miniature flat flashlight. More particularly to a plastic card light which illuminates with one or more light-emitting diodes, powered by a single or multiple battery power supply, which m ay also be integrated into either a flat key card, or credit card.




2. Related Arts




A recent card light is found in U.S. Pat. No. 6,070,990, assigned to the Eveready Battery Company which claims a single “button” battery and spacer, sandwiched between the anode and cathode of a circular LED as a simple switching mechanism. The circular LED protrudes beyond the top and bottom edges of the card light encasement.




The LED mount taught in the Eveready patent requires “forceful insertion of the LED leads in the holes” formed therein. The battery must be mounted during the forceful insertion of the LED lead wires through tiny holes while positioning a battery and spacer both within a cavity for holding the battery and between the two lead wires. A LED which may be quickly and easily mounted while already positioned on the battery, without “forceful” insertion of the LED or lead wires into a small hole is not taught or contemplated by the Eveready patent.




Another card light is shown in U.S. Pat. No. 6,109,762, issued to Hallgrimsson. The Hallgrimsson patent claims another card shaped flashlight which sandwiches an LED lead wire into a deformable plastic switch which may be lowered into contact with a single battery to switch “on” the power.




The Eveready and Hallgrimsson card lights are a small step towards an easily produced flat card light. However, to achieve efficient low cost production and/or increased illumination output, a card illuminator adapted for easy LED mounting, and which can accommodate one or more LEDs and multiple battery cells, while maintaining a thin profile, would be useful.




Plastic key blanks, formed integrally within the plane of a card are represented in the art. U.S. Pat. No. 4,677,835, issued to Almblad, teaches an integrated hinge element connecting a plastic key to a card thereby allowing the key to be displaced from the card and twisted. U.S. Pat. No. 5,046,343, issued to Miwa teaches an insert-molded key and flat card. The Miwa patent illustrates a hinge pin, insert molded into a flat card and used as the pivot point, whereby the key may be rotated out of plane with the card. Another key card, which provides a key connected to the card in a movable fashion, is taught in U.S. Pat. No. 5,544,510 issued to Botteon. The Botteon patent also suggests the placement of bar codes, alpha numeric coding,and the use of a magnetic strip, which can store readable data.




SUMMARY OF INVENTION




The invention herein is a thin credit card flashlight. In some embodiments the card light is no thicker than the LED. The card light may be disposable with the battery supply fixed within a battery and LED receiving chamber by adhesive, sonic weld, glue, or other substantially permanent fixing agent under a chamber cover; or the card light may have a replaceable battery source held in place under a removable chamber cover. A momentary on/off switch is integrated within the device. Certain terminology will be used in the following specification,for convenience and reference and not as a limitation, brief definitions are provided below:




A. “Button battery ” or “button batteries” as used herein refer to one or more coin-type battery including but not limited to batteries containing lithium, and with a thickness of between about 0.2.5 and about 3.0 millimeters and a diameter of between about 10 and about 40 millimeters.




B. “LED” as used herein refers to a light emitting diodes, circular, oval, square, flat, rectangular and flat. LED also includes, but is not limited to, those light emitting diodes which produce a constant output or a blinking output, in a narrow wavelength associated with a specific spectral region, (visible or non-visible) such as red light, blue light, or yellow light, IR, UV and those which produce a wide spectrum output comprising more than one distinct spectral region of light.




C. “Data storage region” as used herein refers to barcodes, a magnetic datastrips, optical strips, 2D data matrix symbologies, holograms, holographs, dataglyphs, serial numbers, alpha numeric symbols, symbols, and characters.




D. “Representational material” as used herein refers to information, picture, graphics, codes, glyphs, icons, trademarks, logos, visual patterns, art, photographs, digital images, promotional literature, symbols or characters.




In some embodiments the LED cathode and anode lead wires comprise the momentary switch, with one lead positioned in-line but remote from the battery supply. The remote lead is separated from the battery supply either by a spacer or integral body spring, until the spacer or integral spring is deformed under pressure thereby switching “on” the current. In other embodiments either the anode or cathode lead is off-set from the battery supply and a conductive member, either mounted to the chamber cover or held above the offset lead wire, is used to connect the battery supply to the LED.




Promotional material may be stenciled onto the flat card light (

FIGS. 1E and 2C

) plastic keys may be integrated into the card light housing forming a combined card light and key holder (FIG.


3


). The card light may also be integrated into a credit card assembly to provide a combination light and credit card (FIG.


4


).




A unique tabbed LED (

FIG. 1A

) has also been developed for this card light. The tabbed LED forms a latch which mates with a catch on the card light casing. The direct mount of the LED to the casing, without having to insert lead wires through holes, allows for rapid assembly and simplifies battery placement and switch assembly.




The features of the invention believed to be novel are set forth with particularity in the appended claim. The invention itself, however, both as to configuration, and method of operation, and the advantages thereof, may be best understood by reference to the following specification, abstract, claims and accompanying drawings.

Detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for claims and as a representative basis for teaching one skilled in the art to variously employ the present Invention in virtually any appropriately detailed structure.




The preferred embodiment of the card light (FIGS.


1


A-


1


D)generally designated


10


, is constructed on a substantially planar semi-rigid plastic body


11


with a battery supply and LED receiving chamber


12


formed therein, and with a chamber cover


13


which mates over the battery supply and LED receiving chamber


12


A non-exhaustive list of plastics which the plastic body


11


may be constructed of include ABS, vinyl, polypropylene, polycarbonate, ABS with stiffening additives, rubberized ABS, and/or polyethylene.




The chamber cover


13


should be constructed of a material which is both adequately flexible to allow deformation and adequate memory to return to the non-deformed state. A non-exhaustive list of suitable construction materials for the chamber cover


13


include coated paper, plastic rubberized plastic, silicone, rubber, impregnated paper, polypropylene, vinyl, polyethylene, ABS, styrene, polycarbonate, laminated paper, Mylar, a or any suitable multi-layer laminate. The chamber cover


13


may be textured on its surface to distinguish top from bottom, direct the user to the momentary switch, and/or provide a reflective-like surface. The chamber cover may be substantially clear with printing adhered to its back side (which will reduce rub-off) and viewed through its front-side. The chamber cover may be textured on its surface to reflect light. The chamber cover may be a multi-layered laminate with printed material laminated between one more layers.




An optional inactive portion


14


of the planar plastic body


11


may be formed adjacent to the battery supply and LED receiving chamber


12


The planar plastic will preferably have an edge


15




a


with a thickness between about 0.85 mm and about 3.5 mm. The edge


15




a


may be tapered, rounded, or beveled


15




b


around some or all of its periphery. A boundary surrounding the battery supply and LED receiving chamber


12


is defined by a ridge


16


which rises above the battery supply and LED receiving chamber


12


by about the thickness of the chamber cover


13


.




Formed as a part of the battery supply and LED receiving chamber


12


is a battery holster


17


which is adapted to accept the power supply for the card light, shown in this embodiment as button batteries


500


. Also within the battery supply and LED receiving chamber


12


is a LED mount


18




a


, of a size and shape to accept the selected LED


100


. In this preferred embodiment the LED


100


may have mounting tabs


110


extending from, or affixed to, its sides which are useful to facilitate fast and accurate placement and mounting of the LED


100


within the tab guides


18




b


of the battery supply and LED receiving chamber


12


. However, a flat LED, similar to the “HSMx-C1110/170/190/C191 High Performance ChipLED” manufactured by Agilent Technologies, Inc., or the “ESM-3070” series LED, manufactured by Elekon Industries, in Torrance, Calif. may also be affixed within the LED mount


18




a


. Moreover, the specification of a flat LED is not intended as a limitation on the scope of the invention, a circular light emitting diode such as the HLMA-QH00-UW001 “Subminiature High Performance AllnGAP LED lamps” manufactured by Agilent Technologies (FIG.


1


C), or an oval shaped LED such as the IHD 2651 or the IGD 2651 “2×3 mm Oblong” manufactured by IDEA, Inc., in Brea, Calif. may be substituted for the flat LED called out for.




Formed in the planar body


11


extending from, and connected to, the LED mount


18




a


is a first LED lead wire channel


19




a


through which the cathode


101


lead wires extend to the battery holster


17


. Also formed in the planar body


11


is a second LED lead wire channel


19




b


through which the anode lead wire


102


extends into a switching channel


19




c


, also formed in the planar body


11


which forms part of the momentary switch for the card light (FIG.


1


D).




To complete the assembly of the card light


10


two button batteries


500


are inserted into the battery holster


17


on top of, and conductively in contact with, the cathode lead wire


101


. A contact strip


550


is affixed to the underside of the chamber cover


13


and positioned to conductively mate with the top of the button batteries


500


and sit remotely above the anode lead wire


102


when the chamber cover has been affixed above the battery supply and LED receiving chamber


12


and within the boundary formed by the ridge


16


. The contact strip


550


may be a conductive foil held to the chamber cover


13


by adhesive. The contact strip


550


may also be formed as a conductive portion of a layer forming the chamber cover


13


, a conductive ink printed on the chamber cover, or a thin conductive wire. The contact strip should be no thicker than about 1 millimeter, preferably between about 0.20 and about 0.75 millimeters and most preferably less than about 0.20 millimeters




A suitable battery supply may include one or more of the Poly-carbonmonofluoride (BR series) lithium batteries or the Manganese dioxide (CR series) lithium batteries either with a height, preferably of 3 mm or less, manufactured by Matsushita Electric Corporation of America (Panasonic).




The above examples of button batteries are not an exhaustive list of possible power supplies, nor is the above list intended to act as a limitation on the doctrine of equivalents. A flexible flat power supply manufactured by Paper Power in Israel, (

FIG. 6

) may be adapted as a power supply, dependent on the current and amperage requirements of the selected LED.




It is also within the intended scope of this invention that as few as one and as many as 12 button batteries may be substituted in place of the two button batteries shown. It is within the scope of this invention that any battery or combination of batteries with the appropriate size and current characteristics could be substitutes for the button battery or power supply called out for. The choice of the power supply, button battery or button batteries for a particular card light will be dependent on the number of LEDs being powered, the current requirements of the LED(s) and the intended usage of the card light.




To switch “on” the card light


10


the user


1000


merely press down on the chamber cover


13


, at the switch region


2000


, thereby urging the contact strip

connecting the LED too to the button battery


500


.




Not shown is the release of the switch region


2000


and the return of the chamber cover


13


to its non-distorted shape. A lead support region


103


which buttresses the anode lead wire


102


against the chamber cover


13


may also be added whereby the anode lead wire


102


is urged against the bottom of the second LED lead wire channel


19




b


thereby reducing the occurrence of accidental switching “on” of the card light via the anode lead wire


102


lifting up and making contact with the contact strip


550


.




To maintain minimum card light thickness (

FIG. 1E

) the LED's cathode lead wire


101


may be placed within a lead lowering guide


150


thereby securing a portion of the cathode lead wire


101


within the bottom of the battery holster


17


while urging a small portion of the cathode lead wire


101


into contact with the first terminal


501


of the button batteries


500


. The contact strip


550


rests on the second terminal


502


of the button batteries. To switch on the light, (FIG.

F. To allow proper alignment of the contact strip


550


with both the button battery


500


and the anode wire lead


102


the placement of the contact strip


550


may be adjusted. A non-conductive spacer


23


may also be added within a spacer guide


24


to act as a fixture to urge the anode lead


102


downward against the plastic body. A logo


600


,


601


,


602


or other representational material may also be added to the surface of the planar body


11


and/or the chamber cover (FIGS.

) of the card light a resilient, conductive and flexible switching strip


43


is placed in conductive contact over the button battery


500


and supported above the anode lead wire


102


, within the first and second switching strip guides


41


and


42


. To complete the assembly the chamber cover, of a size corresponding to the battery supply and LED receiving chamber


12


is affixed over the battery supply and LED receiving chamber


12


. A measure of non-conductive fixture material


44


such as silicone, rubber or epoxy (

FIG. 2B

) may be added to the end of the anode lead


102


to urge the anode lead wire


102


to remain against the bottom of the plastic body


11


. Those skilled in the art will realize that other materials such as rubber or plastic spacers, pliable plugs, hard plugs or tape may serve the equivalent function of the globular material


44


. One or more magnets


45


may be affixed through the pastels body which will enable the card light to be attached to a an appropriate surface.




Shown in this embodiment is a circular LED


100


. Two circular LED suitable for use are the “HLMA-QH00-UW011 Subminiature High Performance AllnGAP LED lamps” manufactured by Agilent Technologies, or the“KM2520xxx001,002 or 003 Subminiature Solid State Led Lamps, manufactured by King Bright. Multiple LEDs, oval shaped LEDs, and flat or side emitting LED may also be utilized in lieu of the circular LED illustrated.




To switch “on” the card light


40


the operator (not shown) merely depresses the pre-selected switch region


2000


on the surface of the chamber cover


13


, and the switching strip


43


is momentarily placed in contact with the anode lead wire


102


thereby switching on the LED


100


.




Throughout this specification, the terms anode and cathode are used interchangeably, by simply reversing the battery terminal connections those skilled in the art will realize that the connection of the LED may be reversed in such a fashion. Any such configuration changes are anticipated by and within the scope of this invention.
