Description
[0001] This application claims the benefit of U.S. Provisional
Application No. 60/109,517 filed on Nov. 23, 1998, which is
incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] The present invention generally relates to safety and sports
equipment and accessories which are illuminated by
electroluminescent phosphors arranged in an electroluminescent
light source, particularly, a cable or wire-like light source, to
enhance the appearance of the product and to improve visibility of
the user. As increasingly more people are becoming health
conscious, exercise and recreational activities are no longer just
carried out during the daylight hours. Many sports activities are
being conducted in low light, dusk, or dark surroundings. The
present invention is intended to make sports enthusiasts more
visible during these low light conditions.
[0003] In addition, rescue personnel and construction workers are
required to perform duties during low light or no light conditions.
Over the years, there have been efforts to render rescue personnel
and construction workers visible during reduced visibility
conditions. However, until now, an adequate solution has not been
achieved.
[0004] Finally, efforts have been made to alert individuals of
particular conditions using barriers, signs, wall barriers, cones,
and barrels, for example. However, until now, there has not been an
adequate solution for rendering these alerting devices visible
during low light or no light conditions.
[0005] Previous methods for illuminating safety and sports
equipment, as well as clothing and accessories, have included
incorporating incandescent lamps, LEDs, and reflective materials
into the various articles. However, these methods suffer from the
following disadvantages.
[0006] Products and devices incorporating incandescent light bulbs
and LEDs are typically bulky and relatively heavy as compared to
their light emitting power. These conventional light sources are
prone to fail because they are not shock proof or water proof.
Incandescent lights and LEDs, to a lesser extent, produce heat that
may become uncomfortable to wear when incorporated into a garment
or used in a product proximate to a flammable solution, vapor or
material. Similarly, incandescent lamps and LEDs have to be used
with caution because they are large and tend to protrude from the
surface of the product and may be easily damaged. In addition, LEDs
illuminate a very small area that can only be viewed at a limited
angle. Therefore, a large quantity of LEDs are required to achieve
a large field of view.
[0007] Typically, because reflective material is not
self-illuminating, it can only be seen when light impinges upon it.
Reflective material is only as good as the light that it reflects,
therefore, visibility resulting from reflective material is limited
to a short distance.
[0008] Thus, there is a need for improved means for providing
illumination to sports and safety equipment, as well as apparel and
accessories.
[0009] Electroluminescent phosphors arranged in electroluminescent
light sources or lamps have been developed in which the
electroluminescent phosphor fibers emit light upon application of
an alternating current to the fibers. Electroluminescent lamps have
typically been arranged as a flat strip. However, a wire-like
electroluminescent lamp has recently been developed, as described
in U.S. Pat. No. 5,485,355, which is herein expressly incorporated
by reference.
[0010] The wire-like electroluminescent light source includes at
least two electrodes arranged to create an electric field between
them upon application of a voltage, and at least one type of
pulverulent electroluminophor dispersed in a dielectric binder and
disposed proximate to the electrodes to emit light of a specific
color(s) upon application of the voltage to the electrodes. A
transparent sheath encases the electrodes and the
electroluminophor.
[0011] The wire-like electroluminescent light source is flexible,
shapeable and radiates light uniformly in all directions. The light
source may be monochrome or polychrome, depending upon the type of
electroluminophor powder(s) used.
[0012] The wire-like electroluminescent light source is completely
UV resistant and waterproof. The phosphor fibers are durable,
flexible, elastic, demand little power and are not harmful to the
environment. The light sources do not generate heat, or harmful
emissions. The wire-like electroluminescent light source is round
and provides 360.degree. of visibility without glare. The wire-like
electroluminescent light source is capable of withstanding extreme
weather conditions.
SUMMARY OF THE INVENTION
[0013] Accordingly, it is an object of the present invention to
provide illumination for safety and sports equipment, clothing, and
accessories that overcomes the problems of the aforementioned prior
art. This illumination is provided using at least one
electroluminescent light source, preferably a wire-like
electroluminescent light source, to secure the safety of
individuals during reduced visibility conditions.
[0014] Yet another object of the present invention is to provide
safety and sports equipment, apparel, and accessories with at least
one wire-like electroluminescent lamp, which is either permanently
or temporarily secured to the product and which includes a power
unit, which may also be permanently or temporarily secured to the
product, either separately from the lamp or as one unit.
[0015] Another object of the present invention is to provide safety
and sports equipment, apparel, and accessories with at least one

extrusion. The encapsulated lamp may be either permanently or
temporarily secured to the product and includes a power unit, which
may also be permanently or temporarily secured to the product,
either separately from the lamp or as one unit.
[0016] It is a further object of the present invention to provide
safety and sports equipment, as well as apparel and accessories,
with at least one wire-like electroluminescent lamp, which may be
accommodated in a sleeve, which is secured, either permanently or
temporarily, to a product to provide illumination of the product,
and thereby improve safety during low light and no light
conditions.
[0017] It is a further object of the present invention to provide
safety and sports equipment, as well as apparel and accessories,
with at least one wire-like electroluminescent lamp, which may be
embedded into a surface of the product to provide illumination to
the product, as well as the user to improve safety during low light
and no light conditions.
[0018] It is still a further object of the invention to provide
safety and sports equipment, as well as apparel and accessories,
with at least one replaceable wire-like electroluminescent
lamp.
[0019] Another object of the present invention is to provide safety
and sports equipment, as well as apparel and accessories, with at
least one wire-like electroluminescent lamp which provides
360.degree. of illumination to the product.
[0020] It is another object of the present invention to provide
safety and sports equipment, as well as apparel and accessories,
with at least one wire-like electroluminescent lamp, which may be
easily manipulated into various shapes in accordance with a design,
logo, symbol, letter(s) or word(s).
[0021] Finally, the objects of the present invention are achieved
by providing at least one wire-like electroluminescent lamp to
sports equipment, apparel and accessories including, but not
limited to, diving suits, life preservers, shirts, shorts, wrist

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0070] The present invention incorporates wire-like
electroluminescent lamps into numerous items such as safety and
sports products, apparel, accessories, and vehicles.
[0071] The present invention is directed to clothing, safety and
sports equipment, and accessories which include at least one
wire-like electroluminescent lamp to help reduce injuries and
casualties that occur with various activities and occupations such
as road construction, ground crews, search and rescue operations,
miners, delivery personnel, aircraft crews, crossing guards,
police, firemen, traffic flaggers, railroad workers, linemen,
paratroopers, paramedics, etc. In sports, the present invention
facilitates safety for those who walk, bike, climb, ski,
motorcycle, run, scuba, sky dive, skateboard, rollerblade, etc. to
become visible or to help in a rescue effort if need be. Further,
the invention is directed to any product that is used in poor
lighting, such as tents, cup holders, etc.
First Embodiment
[0072] According to a first embodiment of the present invention, a
wire-like electroluminescent lamp 2 may be accommodated in a
transparent or semi-transparent sleeve 4A, such as the plastic
sleeve shown in FIG. 1A, to facilitate securing the
electroluminescent lamp 2 to a product. The sleeve 4A may be
permanently or temporarily secured to the product by adhesive,
Velcro, stitching, support loops, or other suitable means. The lamp
may be placed in a transparent or semi-transparent sleeve 4B when
the sleeve is secured to the product or after the sleeve is secured
to the product. The sleeve may provide for removal of the lamp
2.
[0073] As shown in FIG. 1B, the wire-like electroluminescent lamp 2
may also be encapsulated in a transparent or semi-transparent
extrusion 4B, according to known techniques, to provide additional
protection for the lamp 2 to improve its durability. The lamp 2
encapsulated in the extrusion 4B may be permanently or temporarily
secured to the product by adhesive, Velcro, stitching, support
loops, or other suitable means. Both the sleeve 4A and the
extrusion 4B may be clear, colored or multi-colored to further
enhance the effect of the electroluminescent lamp 2.
[0074] FIG. 1C illustrates the wire-like electroluminescent lamp 2.
In appropriate situations, the lamp 2 may be secured by adhesives,
resins, heat welding, lamination, stitching and other conventional
fastening means.
[0075] Securing a wire-like electroluminescent lamp 2 to a product
through any of the above mentioned methods is an effective way to
illuminate safety equipment such as road barriers and cones,
persons wearing clothing, apparel, and products frequently used
during low visibility conditions. The uniqueness of the wire-like
electroluminescent lamp 2 grants the flexibility of design,
allowing the electroluminescent lamp to be as one with the
product.
[0076] Referring to FIGS. 2A-2C, the wire-like electroluminescent
lamp 2 is connected to a power unit 6 via leads (FIG. 2C, 240). The
power unit 6 may be arranged within, or attached to various
locations of the product with adhesive, Velcro, snaps, or other
suitable fastening means. Therefore, the power unit 6 may be either
temporarily or permanently secured to the product.
[0077] The power unit 6 includes a battery 8, which may be a
rechargeable battery or a replaceable battery. The size of the
battery 8 and the specifications of power unit 6 depend on the end
use application of the lamp 2, as is known in the art. The power
unit also includes an inverter 220 for converting the DC power from
the battery to AC power to turn ON the electroluminescent lamp. The
power unit 6 may further include an access door 9 (shown in FIG.
2B), female contacts for connecting the power unit to a recharger
(not shown), and an ON/OFF switch 218 (shown in FIG. 2C).
[0078] The electronics of the power unit are illustrated in FIG.
2C. The ON/OFF switch 218 is placed between a power source 216 and
the inverter 220 in order to allow the user of the product to turn
the electroluminescent lamp ON or OFF positions. The ON/OFF switch
218 may be a two position switch, a dimmer switch, a switch capable
of causing on and off flashing, a remote control switch, or any
other suitable control switch that may cause the desirable effect.
The control switch may also be a manually operated switch or an
automatic switch that is pre-programmed to activate and deactivate
the lamp 2 in response to certain conditions, or may be
photo-responsive so as to, e.g., turn ON at the onset of
darkness.
[0079] The inverter 220, which converts a DC signal to an AC signal
may be of conventional form, or alternatively, may be programmable
or switched under microprocessor control, so that up to at least
sixteen segments or individual electroluminescent lamps may be
operated in a multitude of patterns. A programmable controller and
inverter 220 may be an ISC 802x manufactured by Tech Lite. An 8 bit
microprocessor combined with an electrically erasable read only
memory (EEPROM) facilitates the execution of up to 85 discrete
sequential program steps. The user may thus create programs which
are stored in the memory and executed by the microprocessor.
[0080] As shown in FIG. 2C, the power source 216, inverter 220, and
ON/OFF switch 218 may be assembled in one unit and one or more
wire-like electroluminescent lamps 214 may be connected to the unit
by leads 240. In the examples shown in FIGS. 2A-2C, the
electroluminescent lamp is designed to operate on AC power. Thus,
the power source 216 is preferably a DC power source such as a
battery 8. If the electroluminescent lamp operates on DC power,
however, the DC to AC conversion becomes unnecessary. The power
unit 6 is extremely small and lightweight so that it is essentially
unnoticed by the user. The power unit is not limited to the design
set forth herein, and may include modifications, such as motion and
impact activation.
[0081] The present invention will be described with reference to
specific examples, although it is to be understood that the
invention is not limited to the examples described herein.
[0082] Referring to FIG. 3, at least one wire-like
electroluminescent lamp 2 is secured to the exterior surface of a
shoe 20 which may include running shoes, walking shoes, aerobic
shoes, basketball shoes, tennis shoes, etc. The wire-like
electroluminescent lamp 2 may be encapsulated within an extrusion
4B and secured to the shoe, or accommodated in a sleeve 4A, which
is secured to the shoe, to facilitate securing the lamp to the
product. The lamp 2, encapsulated in an extrusion, may also be
accommoted in a sleeve 4A to enhance durability. The wire-like
electroluminescent lamp 2 may be arranged in various designs or
patterns, including words or letters. The wire-like
electroluminescent lamp 2 itself, or the encapsulated lamp 2, or
the lamp 2 accommodated in a sleeve 4A, may be secured to the shoe
20 with an adhesive, Velcro, snaps, plastic binding, or other
suitable means. Therefore, the wire-like electroluminescent lamp
arrangement may be designed to be removable or permanent. According
to this embodiment, the power unit 6 may be arranged in or on
various locations on the shoe 20, such as comfortably underneath
the inner surface of the sole of the shoe in an area under the
heel, as shown in FIG. 22B.
[0083] The wire-like electroluminescent lamp 2 may be arranged in
virtually any design to enhance the appearance of the shoe 20, or
any other product, and improve visibility of the wearer.
[0084] Referring to FIG. 4, a wire-like electroluminescent lamp 2
is shown secured to clothing such as a jacket 22. The
electroluminescent lamp 2 may be secured to other types of apparel
including sweat jackets, wind breakers, vests, pants, shirts, rain
jackets, etc., and therefore the invention is not limited to a
specific type of apparel. As noted above, the lamp 2 itself or the
lamp encapsulated in an extrusion may be secured to the product, or
the wire-like electroluminescent lamp 2 or the encapsulated lamp 2
may be accommodated in a sleeve 4A and secured to the material. In
addition, the wire-like electroluminescent lamp 2 may be housed in
a plastic or mesh pocket-like area 24 or secured by adhesive,
Velcro, snaps, or other suitable fastening means. Once again, the
wire-like electroluminescent lamp 2 may be arranged in virtually
any design including forms of lettering. The wire-like
electroluminescent lamp 2 may also be secured to other articles of
clothing such as shorts, hats, etc. in a similar fashion.
[0085] In the example illustrated in FIG. 4, the power unit 6 is
arranged in the pocket area 24. However, the power unit 6 may be
arranged in other convenient locations, as may the
electroluminescent lamps 2. In applications for articles of
clothing and apparel, the lamp 2 and the power unit 6 may be
removed to facilitate laundering. Therefore, the lamp 2 and the
power unit 6 may be temporarily secured to the product via a
suitable fastening means, or the lamp 2 and/or the power unit 6 may
be housed in a mesh cloth which may be secured to the product.
[0086] The wire-like electroluminescent lamp 2 may be secured to
other articles to be worn in a similar fashion as stated above,
such as back packs, gym bags, equipment bags, umbrellas, and waist
packs worn by joggers and pedestrians. The power unit 6 may be
arranged in a variety of locations, as also previously
described.
[0087] Perhaps the greatest use for the wire-like
electroluminescent lamps is in the area of safety. Referring to
FIGS. 5A and 5B, at least one electroluminescent lamp 2, either
flat or wire-shaped, is secured to a vest or life jacket/preserver
30. The wire-like electroluminescent lamp 2 and power unit 6 may be
secured to the vest/life jacket/preserver 30 in any manner
described above. The wire-like electroluminescent lamp illumination
provides high visibility to the user, and therefore, increases the
safety of the user, as well as assists in locating victims during
rescue efforts.
[0088] Electroluminescent lamps 2 may also be secured to diving
gear, such as wet suits, diving fins, goggles, and diving tanks,
for example. The diving fins 34 and goggles 36 are illustrated in
FIGS. 6 and 7, respectively. The power unit 6 may be housed in a
pocket 35 arranged on the diving fins 34 or on a band on the side
of the goggles, for example. The power unit 6 may be secured at any
convenient locaton by appropriate fastening means. The wire-like
electroluminescent lamp 2 not only provides ornamentation to the
product, but also provides high visibility of the user, and
therefore, increases the safety of the user.
[0089] The use of a transparent or semi-transparent sleeve 4A
and/or extrusion 4B, for attachment of an electroluminescent lamp
2, extends to any type of material or product that provides
increased utility when visible in hard to see places. Other
examples include a tent 40, as shown in FIG. 8, and a container 46,
such as a tackle/tool box, as illustrated in FIG. 9. Referring to
FIG. 8, at least one wire-like electroluminescent lamp 2 may be
arranged in a transparent or semi-transparent sleeve 4A or
extrusion 4B, and secured to the seams 42 of the tent, by any
conventional fastening means. The lamp 2 may also be secured to
mesh which holds the poles that support the tent 40. This enhances
visibility of the tent 40 on cloudy days and at night. Further, the
electroluminescent wire 2 may be placed within or secured to the
shock corded aluminum or PVC poles to radiate light from the poles
that support the tent.
[0090] Referring to FIG. 9, at least one wire-like
electroluminescent lamp 2 or flat electroluminescent lamp, may be
arranged in a transparent or semi-transparent sleeve 4A, and/or
encapsulated in an extrusion 4B and designed into any shape. The
protective sleeve 4A and/or the power unit 6 may include adhesive
backing that is exposed by a peel away cover and applied with
pressure to adhere. Thus, the lamp 2 and/or the power unit 6 may be
permanently or temporarily secured to the container 46, or any
other object, by the adhseive or other conventional fastening
means. When used in a utility box, for example, this type of lamp 2
allows the user to see equipment without being blinded by the
intense brightness of a halogen lamp or fluorescent bulb. The power
unit 6 may be permanently or temporarily secured to the container
46 using methods previously discussed.
[0091] There are several other beneficial uses of the
electroluminescent lamp 2. For example, as illustrated in FIG. 10,
a wire-like electroluminescent lamp 2 is placed on a bicycle in a
spiral formation to illuminate the bicycle during low light
conditions. The wire-like lamp 2 may be encapsulated in an
extrusion 4B or accommodated in a sleeve 4A. The lamp 2 may be
encapsulated in a substantially flat extrusion which can be wrapped
about a portion or portions of an article, such as the bicycle,
jump rope, pet leash or collar, etc., to provide seamless
illumination. The lamp 2 may also be accommodated in a
substantially flat sleeve which can be wrapped about a portion or
portions of an article. The lamp 2 and power unit 6 in this example
constitute a retrofit unit. The lamp 2 and power unit 6 may be
either temporarily or permanently secured to virtually any article
by a sufficiently strong and compatible adhesive, or any other
suitable fastening means. Commercially available examples of such
adhesives include Spray Mount artist adhesive ID number
62-4953-4825-2, Super 77 spray adhesive ID 62-4437-4930-4, double
coated transparent polyester film tape D.C. part No. 021200-13267,
and 5 mil high performance adhesive transparent tape with P/C liner
D.C. part No. 012100-91055. These products are manufactured by the
3M Company.
[0092] FIGS. 11A-C illustrate lanterns with an electroluminescent
lamp or lamps 2. The lanterns are weather and water proof, and do
not attract insects. The lantern illustrated in FIG. 11A includes a
wire-like lamp 2 and it retracts into a holder for easier storage.
The lantern illustrated in FIG. 11B is designed to rotate and it
may be vacuum insulated with a plastic covering or other suitable
material. The lantern illustrated in FIG. 11C is flexible so that
it may wrap around an object and hook into position. The lantern
may or may not include a base. Further, the lantern may incorporate
either the electroluminescent wire light 2 or the flat
electroluminescent lamp. The power unit 6 may be secured in any
convenient location by conventional means.
[0093] FIGS. 12A-B illustrate jewelry and accessories that
incorporate the wire-like electroluminescent lamp 2 of the present
invention. In FIG. 12A, a pair of party glasses having a wire-like
electroluminescent lamp 2 are shown that are designed to fit the
head and outline the eyes. A neck spiral is also shown. An arm
spiral having a wire-like electroluminescent lamp 2 is shown in
FIG. 12B. A wire-like electroluminescent lamp 2 housed in a sleeve
4A and/or encapsulated in an extrusion 4B may also be incorporated
into hats and visors and pony-tail holders, as shown in FIG. 12C. A
small power unit housing 6 coin batteries may be used to power the
jewelry and accessories.
[0094] FIGS. 13-14 illustrate vehicle safety products that
incorporate the present invention. More specifically, a sign in the
shape of an arrow is shown in FIG. 13. Electroluminescent light
from a wire light 2 or flat lamp is secured to the sign. The light
may pulsate, follow in sequence, or change design to create
attention and divert approaching traffic. Signs of this type may be
secured to a vehicle by means of a suction cup, latch, over the
window hook, or other suitable fastening means. The sign or
multiple signs may also be placed proximate to the vehicle rather
than on the vehicle to provide greater safety. The wire-like or
flat electroluminescent light 2 may also be secured to a sun-visor
or the front and rear windshields. FIG. 14 illustrates a sign for a
vehicle bearing an "S.O.S." signal. The sign may be secured to the
vehicle by any suitable means. In addition, the sign may be
arranged to pivot from a vehicle window to indicate a need for
help, or be arranged proximate the vehicle. The signal provides
high visibility for oncoming traffic, particularly when arranged at
eye-level. It is made of plastic or vinyl type material and
illuminates a message by incorporating at least one
electroluminescent light. The lamp 2 is placed on top of or
sandwiched between the transparent plastic coverings. The lamp
electronics may be connected to a 12 volt car battery as a power
supply or include an independent power unit. Further, the sign may
be manufactured as a part of the vehicle, or separately attached to
the rain trim, window, or door of the vehicle.
[0095] Another safety use of the wire-like electroluminescent lamp
2 is in the field of athletic apparel and accessories. FIG. 15A
illustrates a headband illuminated by an electroluminescent wire 2.
FIG. 15B illustrates an electroluminescent wire-like lamp 2 that is
long enough to wrap across or around a chest or appendage,
effectively spiraling the body for 360 degrees of illumination.
This method of wearing the lamp 2 allows the user to perform
unlimited activities without feeling weighed down by the lamp 2.
The electroluminescent wire 2 may also be secured to mesh cloth
that is secured onto shirts and shorts, for example, to be worn
over regular articles of clothing. In this manner, any article of
clothing or accessory may include illumination from
electroluminescent lamps 2.
[0096] These products may be worn at dusk or at night to increase
visibility, and thus, increase the safety of the user. The
electroluminescent wire 2 may be easily interchanged with
replacement wires and is available in a variety of colors. Multiple
lamps may also be used. Both the headband and the body spiral may
operate on internal battery power or from an independent power unit
that may be attached to a belt, as shown in FIG. 15C.
[0097] FIG. 15D illustrates the power unit 6 having a "jack"
connector for connecting the electroluminescent lamp 2. The "jack"
connector consists of male and female connecting parts that are
known in the art, similar to a headphone jack. In the present
invention, the use of a jack allows the wire-like
electroluminescent lamp 2 or the power unit to be easily
interchanged when the light is dimming, when the lamp 2 wears out,
or when the user desires to change the color of the lamp 2.
Further, although FIG. 15D illustrates only one jack, multiple
jacks may be arranged on the power unit so that multiple wire-like
electroluminescent lamps 2 may be illuminated at one time, having
the same or different colors.
[0098] At least one electroluminescent lamp 2 may also be secured
to a boot 56, shown in FIG. 23, ski boots 58 in FIG. 24, skates 60
shown in FIG. 25, by the methods set forth above. The power unit 6
may be either permanently or temporarily secured to the items shown
in FIGS. 23-25 by the methods set forth above.
[0099] FIGS. 16A-B illustrate a plush, squeezable toy that
incorporates the present invention to provide an ideal night light
for children. FIG. 16A shows the squeezable toy, which is corded
with electroluminescent wire 2, encapsulated in an extrusion 4B,
silhouetting the design of the toy. The lamp 2 may be used without
being encapsulated in an extrusion. The toy illuminates a soft
light powered by a power unit 162 recessed into a pocket housed in
the toy with an ON/OFF switch or push button 164, as shown in FIGS.
16A-B. The bottom or arm of the switch 164 protrudes through the
surface of the toy so that it can be easily activated. The lamp 2
may be arranged in a variety of designs, patterns, including logos
and lettering. The lamp 2 may be housed in a transparent or
semi-transparent sleeve 4A (with or without color(s)). The
electroluminescent lamp 2 can also be used on the bumpers of a crib
or portions of a crib or cradle to illuminate areas of the crib or
cradle. The lamp and power unit may be secured to the toy by any of
the methods set forth above or appropriate conventional means.
[0100] Wire-like or flat electroluminescent lamps 2 may also be
incorporated into other children's toys and accessories such as
jump ropes and doll houses (not shown). A children's book with an
electroluminescent wire 2 or flat light built into the book and
story line is shown in FIG. 20A. An ON/OFF switch is provided to
allow for participation, and the battery pack is housed in the
spine of the book and/or the cover of the book, as shown in FIG.
20B. Another children's toy that may be illuminated by an
electroluminescent lamp 2 is a doll house (not shown).
[0101] FIG. 17 illustrates a PVC plastic chain link having
electroluminescent wire that is threaded or woven as part of the
chain to generate a flashing or continuous light. This product
easily conveys partitioning or separation of an area and may be
powered by a power unit or electrical outlet.
[0102] A clear, PVC walking cane incorporating electroluminescent
wire for greater visibility is shown in FIG. 18A. A power unit 182
having an ON/OFF switch 184 is encased in the handle or secured to
the outside of the cane, as shown in FIG. 18B.
[0103] FIG. 19 illustrates a holiday decoration for a door, wreath,
lawn display, mail box, or tree ornamentation that is illuminated
by a wire or flat electroluminescent lamp 2. The electroluminescent
lamp may also be used as a sign or added to a sign which conveys a
message. The electroluminescent lamp may be formed into the desired
shape by die molding or the like. The decoration may or may not be
encased in PVC housing, and the sleeve 4A and/or extrusion 4B may
be transparent or have color. Further, the decoration may be
powered by a standard electrical outlet hook up or by a power unit
secured to the back of the decoration with suction cups, Velcro, or
any other suitable means. The electroluminesent lamp may be secured
to structures to provide indoor or outdoor illumination.
[0104] FIGS. 21A-B illustrate bicycle seats that are illuminated by
electroluminescent light 2. In FIG. 21A, the seat supports the
buttocks by circle-like supports to remove pressure from a male's
prostate, creating a more comfortable seat. In FIG. 21B, a seat in
the shape of a hot dog bun envelopes the thigh part of a leg to
increase mobility and flexibility and to relieve the pressure from
the prostate. The seats illustrated in both figures are lighted by
at least one electroluminescent lamp 2 for design and safety
purposes. Another example of a safety use of the present invention
is to secure the wire-like electroluminescent lamp 2 to a carriage,
buggy, or wheeled-chair (not shown). The wire-like
electroluminescent lamp 2 may be included in a transparent or
semi-transparent sleeve 4A and/or encapsulated in an extrusion 4B,
and sewn to the material of the carriage, or it can be secured by
the additional methods described herein and conventional fastening
means. Again, the power unit 6 may be arranged in a pocket area or
other convenient location as previously described.
[0105] The electroluminescent lamp may be secured to ladders, and
safety nets.
Second Embodiment
[0106] Another method for securing the electroluminescent lamp 2 to
a desired object is to implant or insert it within the desired
material. As illustrated in FIGS. 22A-B, both the wire-like
electroluminescent lamp 2 and the power unit 6 may be arranged
within the sole 50 of a shoe 20. The sole 50 may include a
transparent area 52 corresponding to the location of the wire-like
electroluminescent lamp 2 such that the light from the wire-like
electroluminescent lamp 2 is visible through the transparent area
52. Alternatively, the entire sole or portions of the sole may be
transparent, semi-transparent, colored or multi-colored and
illuminated by wire-like electroluminescent lamp 2.
[0107] The wire-like electroluminescent lamp 2 may be embedded
within the boots 56, the ski boots 58 or the skates 60 respectively
shown in FIGS. 23-25. The lamp may be embedded within the entire
product or portions of the product which are transparent,
semi-transparent, colored or multi-colored. The lamp 2 may be
encapsulated in an extrusion 4B and then embedded in the
product.
[0108] In addition, the electroluminescent lamps may be secured to
the exterior of the above items by the means set forth in the first
embodiment with respect to the sleeve or where the lamp is
encapsulated in an extrusion.
Third Embodiment
[0109] Another application of securing the electroluminescent lamp
2 to an object for enhanced visibility is by placing it in a
recessed portion or channel of any rigid surface, such as the
surface of a skate board 66, as illustrated in FIGS. 26-28.
Referring to FIG. 28, a wire-like or flat electroluminescent lamp 2
may be arranged in a channel 292 that is formed on the surface of
the board 66 with grooves for recessing the wire-like or flat
electroluminescent lamp 2. Further, a transparent or
semi-transparent layer may be placed over the rigid surface 66 with
the recessed lamp 2 to provide additional protection for the
wire-like or flat electroluminescent lamp 2. The power unit 6 may
be arranged on the exterior of the rigid surface 66, as illustrated
in FIG. 26, or recessed into the rigid surface 66, as illustrated
in FIG. 27.
[0110] The product may include canals or channels for cradling the
lamp. The power unit 6 may also be secured to the boots 56, ski
boots 58, and skates 60 in the manner described above.
[0111] Note that the wire-like or flat electroluminescent lamp 2
may also be secured to the rigid surface 66 by any of the methods
previously described, such as by an adhesive, Velcro, snaps or
other suitable means, and therefore is not limited to the use of
recesses or channels.
[0112] The wire-like or flat electroluminescent lamps 2 may be
secured to other rigid surfaces such as on jet skis, snow skis,
snowboards, snow mobiles, go-carts, etc., and other sports apparel
and accessories in the same recessed or channeled fashion as stated
above. Further, the wire-like electroluminescent lamp 2 may be
housed in a sleeve 4A secured to the product. In the above
embodiments, the lamp 2 may be encapsulated in an extrusion 4B for
added durability. The lamp may be formed into a variety of designs
and lettering, including logos and brand names, on the surface.
Formation of the designs and lettering may also be achieved by
using a screen printing method wherein phosphor particles are
selectively placed to create a design or logo that emits light.
[0113] Vehicles, such as rescue boats, may also be equipped with
wire-like electroluminescent lamps 2 to increase visibility of the
vehicles during low light and no light conditions. FIG. 29
illustrates the wire-like electroluminescent lamp 2 secured to the
exterior of a rescue boat 70 or recessed into the rescue boat 70.
The electroluminescent lamps may also be secured to the sails of a
boat as shown in FIG. 29, or flags arranged on the boat by means
described in the first embodiment. The power unit 6 may be arranged
in any convenient location and secured as previously described.
[0114] For safety vehicles, the electroluminescent lamp 2 may be
arranged in the shape of a cross, or arranged to spell a word such
as "rescue" to indicate that the vehicle is a rescue vehicle. The
wire-like electroluminescent lamp 2 may also be secured to the
surface of a vehicle by any of the methods previously described,
such as by an adhesive, Velcro, snaps, or other suitable means, and
therefore, is not limited to the use of recesses or channels.
[0115] Other examples where the wire-like electroluminescent lamps
may be arranged under a transparent or semi-transparent layer of a
rigid surface include diving fins 34 (as illustrated in FIG. 6),
goggles 36 (as illustrated in FIG. 7), life rafts 72 (as
illustrated in FIG. 30), barriers such as traffic cones 74 (as
illustrated in FIGS. 31A-B), vehicles 76 (as illustrated in FIGS.
32A-B), road barriers 78 and 80 including fencing (as illustrated
in FIGS. 33A-B), and signs 82 (as illustrated in FIG. 34). This
arrangement provides additional protection for the wire-like
electroluminescent lamp 2. The lamp and power unit may also be
secured to the foregoing products according to the first embodiment
of the present invention.
[0116] A wire-like electroluminescent lamp 2 may also be placed in
a channel formed in the foam of a safety helmet such that a
transparent or semi-transparent shell of the safety helmet is
formed over the foam including the wire-like lamp, as shown in FIG.
35. This will not only enhance the appearance of the helmet, but
also help preserve and shelter the wire-like electroluminescent
fibers from damage without compromising the integrity of the
helmet. By placing the wire-like electroluminescent lamp under the
shell, the aerodynamic design of the helmet is maintained, without
reducing the safety of the helmet.
[0117] Another benefit can be achieved by securing an
electroluminescent lamp 2 into a recess of a rigid surface to
provide visibility to products that are frequently used in hard to
see places. An example is illustrated in FIG. 36A wherein an
electroluminescent lamp 2 is secured to a recess formed on the
perimeter of a cup holder 90 used in any type of vehicle. The
benefit gained here is allowing a user to place a drink into the
holder 90 with little effort during the night, or while driving
through tunnels, etc., when the cup holder would otherwise be
difficult to find without a considerable amount of effort. FIG. 36B
illustrates the hook up of the illuminated cup cylinder 90 to a 12
volt battery system of a vehicle. Leads from an ash tray and the
cup holder 90 are connected to a 12 volt reduction transformer 372.
The cup holder 90 may also operate with an independent power unit.
In FIG. 36C, a portable cup holder is illustrated that operates
independently of the vehicle battery supply.
[0118] The electroluminescent lamps 2 may be temporarily or
permanently secured to all of the products stated above by
adhesive, Velcro, snaps, or other suitable means, and therefore is
not limited to securing the electroluminescent lamps 2 to the
surfaces by using a recess or channel formed therein. Further, a
thin transparent film may be placed over an electroluminescent
lamp, which may or may not be encapsulated in an extrusion, that is
secured on top of a rigid surface to provide protection and
increase durability. Moreover, a reflective film may be provided
over the lamp to enhance visibility. As noted above, the power unit
6 may also be either temporarily or permanently secured to the
surface.
[0119] The wire-like electroluminescent lamp 2 of the present
invention is independently powered by its own energy source which
may be battery, solar, photovoltaic, or AC format energy. Use of
the electroluminescent lamp 2 adds benefit in both the sport and
industrial markets, in any situation where added visibility
promotes safety or adds another dimension to product design.
[0120] The present invention incorporates a wire-like
electroluminescent lamp 2 into all apparel, including sports and
safety apparel, adding another dimension to clothing. The wire-like
electroluminescent lamp 2 adds a visible difference to clothing by
illuminating garments in a subtle fashion.
[0121] The wire-like electroluminescent light 2 may also be
incorporated into bags, shoes, sneakers, belts, etc., that work as
accessories to apparel and into almost all sport and safety
equipment. The specifi uses mentioned herein are only a few of
those that would benefit from adding electroluminescent fibers. One
skilled in the art could secure the electroluminescent wire light
to almost any safety device or sport accessory.
[0122] Moreover, in addition to providing safety, the wire-like
electroluminescent light can be used to create exciting and
innovative designs to give the product a hi-tech appearance,
thereby providing ornamentation to the product. The wire-like
electroluminescent lamp 2 can even be used to personalize items by
arranging the wire-like electroluminescent light to spell a name or
a logo.
[0123] The wire-like electroluminescent lamps may be made in a
variety of colors such as yellow, green, and orange, and may be
monochrome or polychrome, as described in U.S. Pat. No. 5,485,355,
noted above. The colors are vibrant, and may be made to change in
sequence and blink in series by use of a programmable controller
and inverter discussed above. The color may result from the type of
phosphors used as described in the above-referenced patent. In
addition, the color may result from mixing the phosphors with dyes
or from placing a wire-like electroluminescent lamp in a colored
sleeve 4A or extrusion 4B. Further, in each of the above-noted
embodiments, the wire-like electroluminescent lamps may be arranged
such that the transparent or semi-transparent material over the
lamp, which may be clear or colored, is reflective to add
additional safety.
[0124] In addition, the wire-like electroluminescent lamp 2 in all
of the embodiments herein may be housed in a sleeve. The
temporarily housed wire-like electroluminescent lamps 2 may be
easily interchanged with replacement wires that are available in an
assortment of colors, as discussed above. In addition, the sleeve
may be provided in a variety of colors. In addition, in all of the
embodiments described herein, the power unit may be waterproof.
[0125] While specific examples have been described herein, it is to
be understood that the invention is not limited to these examples.
One skilled in the art may recognize that modifications can be made
without departing from the scope and spirit of the invention.
