Preferably, the light source is an electroluminescent lamp, which is combined with a graphic layer producing an animated EL panel.
Description
- 1. Field of the Invention
- The present invention relates to an electroluminescent device and, more particularly, but not exclusively, to an electroluminescent device that can be affixed to shoes, where the electroluminescent device provides radiant visible light.
- 2. Prior Art
- U.S. Pat. No. 4,848,009 to Nicholas Rodgers discloses articles of footwear that are provided with a battery and a light source and a motion responsive switch to intermittently connect said battery to the light source. The light source is preferably an LED, and there is preferably a circuit to extinguish the light after a predetermined interval.
- U.S. Pat. No. 6,843,578 to James Chung teaches a system of illuminated footwear article utilizing electroluminescent light strips, which are randomly illuminated according to the movement of the person wearing said article(s). Illumination control is accomplished by means of a DC to AC converter and various types of switches. Such switches include a random pressure switch, a random or controlled sequencer, an orbiter random motion switch, or a combination of such switches. Such switching allows for random or sequenced illumination of light strips based on user movement.
- The prior art teaches electroluminescent footwear wherein the movement of the footwear activates the illumination of the electroluminescent light or LED. A problem associated with a switch activated by movement is that the electroluminescent light, or LED, can be actuated during shipment, causing the battery to run down, even when the footwear is not being worn. What is needed is electroluminescent footwear that has a sensor system that prevents accidental illumination. A second problem with the current art is that the batteries are enclosed in a unified assembly wherein, when the battery expires, the shoe no longer illuminates. What is needed is a power pack that can be replaced, and / or recharged.
- Accordingly, the present invention is footwear comprising at least one light source located on said footwear, to be visible, exteriorly thereon; a power source for energizing said light source; a circuit for selectively, electrically, connecting said power source with said at least one light source to illuminate said source; a pressure switch, which while depressed is “closed”, and when not depressed is “open”; wherein the circuit is adapted to disconnect said power source from said light source a predetermined time after said pressure switch is “open”; wherein said circuit being adapted to connect said power source to said light source when said switch is “closed”. Preferably, the light source is an electroluminescent lamp, but other light sources, such as LEDs are also anticipated. The pressure switch is selected from switches that will automatically return to the “open” position when the switch is not depressed, for instance, when the footwear is not worn. Examples of suitable pressure switches include certain spring and rubber switches, membrane switches, and certain reed switches. The pressure switch is preferably located in the sole of the footwear, so that when the footwear is worn, the power source is connected to said light source when the pressure switch is “closed”. The preferred light source is an electroluminescent lamp. When employing an electroluminescent lamp, the circuit is further comprised of an inverter and a sequencer, where the sequencer provides a timed flashing light sequence, and the inverter provides an AC voltage. The electroluminescent lamp is preferably combined with a graphic layer, therein providing a sequenced illuminated graphic panel that is exteriorly visible on the footwear. The sequenced illuminated graphic panel can have multiple graphic and individually timed illuminated electroluminescent lamps, such that the sequenced illuminated graphic panel produces an animated image.
- The power source is typically a battery, where the preferred battery is rechargeable. The footwear has a sole with a compartment and an access thereto, wherein the battery is housed and accessible. The battery is in electrical communication with an electrical port that can couple to an external recharging source. Additionally, the footwear can have an exterior solar panel that, in the presence of sunlight, provides some electrical power to the rechargeable battery.
- The footwear can be further comprised of a photo sensor switch that overrides the pressure switch. The photo sensor switch has two states, an “off” state in the presence of light, and an “on” state in the absence of light. When the photo sensor switch is in the “off” state, even when the pressure switch is “closed”, the power source is not connected to the light source. When the photo sensor switch is in the “on” state, then when the pressure switch is “closed” the pressure switch is not overridden, and power source is connected to the light source. The photo sensor switch and the pressure switch combine to provide an interlock that prevents the circuit from inadvertently becoming activated and drain down the power source, when the footwear is not being worn. Unlike a motion responsive switch, as described in U.S. Pat. No. 4,848,009, a pressure switch is unlikely to activate during shipment, as there is substantially no change in the pressure. The photo sensor switch prevents activation in daylight, except when the footwear is being worn, as the presence of a foot blocks the entrance of daylight. The interlock can be further secured by utilizing a membrane switch located in the interior of the footwear, and selecting a membrane switch that has an electroluminescent backlit panel that illuminates only when the pressure switch is depressed. In a dark environment, such as a closed box, if the pressure switch is accidentally depressed, then the electroluminescent backlit panel will become illuminated. Further, unless there is an intervening obstacle filling the interior of the footwear, such as a foot, then the photo sensor switch will detect the light and deactivate the pressure switch, therein shutting down the connection of the power source to the light source.
- The foregoing and other objects will become readily apparent by referring to the following detailed description and the appended drawings in which:
-

Most of the electronic components supporting the graphic EL panel are located in the sole 15 of thefootwear 10 in a compartment 36 (shown in ghost). The compartment is accessible through adoor 38 shownFIG. 3 . Referring toFIG. 2 , thefootwear 10 has an opening 20 through which is visible apressure switch 48 that is seated in theinner sole 16. Thepressure switch 48 actuates a sequencer, which generates timed electrical AC power to the EL lamps. In the embodiment, there are a pair of graphic EL panels, 30a on the medial side and 30 b on the lateral side.FIG. 3 is a bottom view of thefootwear 10, wherein theoutsole 18 has access to thecompartment 36 throughdoor 38. Thecompartment 36 houses the power source, arechargeable battery 40, and thecircuit board 42 comprising theinverter 46 and thesequencer 44.FIG. 4 illustrates the medial side view of the invention,footwear 10. Shown are the medial ELgraphic panel 30 a mounted on themedial sidewall 14 a of thefootwear 10, with atoe 12, a sole 15, and aheel wall 24. Mounted in theheel wall 24 is aphoto sensor switch 50. The position ofphoto sensor switch 50 is selected such that, when the footwear is worn,photo sensor switch 50 is directed toward the interior 22 of thefootwear 10, such that the switch is covered by the wearer's foot. For footwear not having a heel wall, the location would appropriately be either the inner sole 16 or asidewall 14. In the sole 15 of the footwear, near theheel 24, is anexternal charge port 26, for connecting to a battery charger. - Referring to
FIG. 5 , the front of thefootwear 10 is covered with asolar panel 52, which provides electricity to thepower source 40 comprising rechargeable batteries. The medial ELgraphic panel 30 a is mounted on themedial sidewall 14a, and the lateral ELgraphic panel 30 b is mounted on thelateral sidewall 14 b of the footwear. - Referring to
FIG. 6 , each of the EL graphic panels, 30 a and 30 b, are comprised of agraphic layer 34 and threeEL lamps 32 a-32 c and 32 d-32 f. Each panel typically has acommon lead 80. When thesequencer 44 is initiated by depression of thepressure switch 48, the EL graphic panels are lighted for a specified period through a specified number of loops in a specified order. The DC current emanating from thepower source 40 is converted to an AC current byinverter 46. Typically, the inverter generates voltages around 70-120 Volts, and frequencies of 800-2,000 Hz. Thepressure switch 48, incircuit 100, is selected from pressure switches that, when not depressed, automatically return from “closed” position to the “open” position. Examples are certain spring and rubber switches, membrane switches, and certain reed switches. The pressure switch is only in the “closed” position while it is being depressed, that is, when the footwear is being worn. Membrane switches are relatively inexpensive and durable, and perform suitably. As shown, thepower source 40 can be in electrical communication with anexternal charging port 26, and asolar panel 52. Rechargeable batteries are in thepower source 40, and thepower source 40 is accessible so that the batteries can be changed. The circuit is preferably further comprised of aphoto sensor switch 26. The photo sensor switch has two states, an “off” state in the presence of light, and an “on” state in the absence of light. When the photo sensor switch is in the “off” state, even when the pressure switch is “closed”, the power source is not connected to the light source. When the photo sensor switch is in the “on” state, then when the pressure switch is “closed” the pressure switch is not overridden, and power source is connected to the light source. The photo sensor switch and the pressure switch combine to provide an interlock that prevents the circuit from inadvertently becoming activated and draining down the power source, when the footwear is not being worn. -
