## Background
FIELD OF THE INVENTION
The present invention relates to a wirelessly connectable light source, and in particular to a wirelessly connectable light source that is wirelessly chargeable and is mountable to an article of fabric product or leather product through weaving, welding, adhesive bonding, and sewing to give off light.
BACKGROUND OF THE INVENTION
Conventionally, to additionally mount a light-emitting element, such as a light-emitting diode (LED) to a personal item, such as garments, pants, shirts, underwear, or brand bags (or ordinary bags), leather bags, leather belts (waist belts), raincoats, hats, or jackets, the only known practice is to mount a light-emitting element to a jacket or a hat to improve nighttime atmosphere, amusing, or aesthetics effect.
Further, these articles are made by applying proper jointing techniques, such as sewing and stitching, bonding (such as ultrasonic bonding), and/or thermal fusion, to joint multiple pieces of fabrics, which can be of different materials, different colors, and different shapes. However, it was considered a difficult to mount a light-emitting element to these articles. A conventional solution is to cover and secure the light-emitting element with a transparent, waterproof sheet material. In such a way of securing light-emitting element, the light-emitting element is not actually integrated with the woven parts of these articles, leading to undesired constraints in both the use and the configuration thereof.
Further, electrical power that is used to operate the light-emitting element is often supplied from a rechargeable battery, such as nickel-hydride battery and lithium battery. This rechargeable battery is re-chargeable by a charging device, which is electrically connected in a wired fashion to for example an electrical socket so that the electrical power for charging the battery is supplied through a cable or wire to the rechargeable battery. This limits the spatial range of usage and reduces the convenience of use. Thus, it is desired to provide a light source that can be directly sewn to or woven in an article, such as garment, pants, shirt, underwear, or brand bag (or ordinary bag), leather bag, leather belt (waist belt), raincoat, hat, or jacket.
SUMMARY OF THE INVENTION
An objective of the present invention is to provide a wirelessly connectable light source, and in particular a wirelessly connectable light source that is wirelessly chargeable and can be directly sewn to, welded to, adhesively bonded to, or woven in a product.
To achieve the above objective, the present invention provides a wirelessly connectable light source, which is applicable to an article to which a charging device is coupled. The charging device comprises a transmitter circuit and a power source that is connected to the transmitter circuit so that the power source supplies electrical power to the transmitter circuit and the electrical power is converted by the transmitter circuit into an alternate-current (AC) signal. The wirelessly connectable light source comprises a woven member, a conductor, a receiver circuit, and at least one light-emitting element. The woven comprises a body and an extension section from the body. The conductor is housed in the body. The receiver circuit comprises a rechargeable battery and is electrically connected to the conductor. The AC signal is transmitted from the transmitter circuit to the receiver circuit and is received and converted by the receiver circuit into electrical power that is stored in the rechargeable battery. The light-emitting element is arranged inside the body and comprises a light emission section and at least two conductive sections, wherein the light emission section emits light projecting out of the body of the woven member and the two conductive sections are respectively in electrical connection with the conductor. The wirelessly connectable light source uses the extension section of the woven member to integrate with the article.
As such, the wirelessly connectable light source can be directly sewn, welded, adhesively bonded, woven with an article through the extension section so that the drawbacks of the conventional techniques can be completely overcome.
Another objective of the present invention is to provide a wirelessly connectable light source, which further comprises a control circuit and a switch, wherein the control circuit, the switch, and the rechargeable battery of the receiver circuit are electrically connected to the conductor to allow the rechargeable battery to supply electrical power to energize the light-emitting element for giving off light and the control circuit controls the lighting fashion of the light-emitting element.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention provides a wirelessly connectable light source. In the attached drawings, FIG. 1 illustrates a perspective view of the light source according to the present invention and FIGS. 2-8B respectively show first to sixth embodiments of the present invention. The light source of the present invention is applicable to an article, which is not shown in the drawings. A charging device 9 is coupled to the article (by means of for example clamping, bonding, adhering, or mutual attraction). The charging device 9 comprises a transmitter circuit 91 and a power source 92 connected to the transmitter circuit 91. The power source 92 supplies electrical power to the transmitter circuit 91 and the electrical power is converted by the transmitter circuit 91 into an alternate-current (AC) signal. The article can be for example garments, pants, shirts, underwear, or brand bags (or ordinary bags), leather bags, leather belts (waist belts), raincoats, hats, or jackets, but not limited thereto.
First Embodiment
Referring to FIGS. 1, 2, and 8A-8B, a first embodiment according to the present invention is shown, comprising a woven member 1, at least one light-emitting element 2, an electrical conductor 3, and a receiver circuit 8. In the embodiment shown in the drawings, a plurality of light-emitting elements 2 is included. The light-emitting elements 2 can be light-emitting diodes (LEDs) or organic light-emitting diodes (OLEDs).
The woven member 1, which can be made of for example fabric, cotton, or a knitted material, comprises a body 11 and at least one extension section 12 extending from the body 11. In the embodiment shown in the drawings, the woven member 1 comprises one extension section 12. The light-emitting elements 2 and the conductor 3 are arranged inside the body 11. Alternatively, the light-emitting elements 2 and the conductor 3 can be woven within the body 11 in weaving the woven member 1.
Each light-emitting element 2 comprises a light emission section 21 and at least two conductive sections 22. The two conductive sections 22 are respectively in electrical connection with the conductor 3. In the first embodiment shown in the drawings, the two conductive sections 22 are conductive pins and the conductor 3 comprises a flexible printed circuit board. As such, when electrical power is supplied to the conductor 3, all the light-emitting elements 2 can be energized for emission of light.
The receiver circuit 8 is electrically connected to the conductor 3 to allow the AC signal transmitted from the transmitter circuit 91 to be received by the receiver circuit 8. The receiver circuit 8 comprises a receiver induction coil 81, a secondary receiving resonant circuit 82 connected to the receiver induction coil 81, an AC/DC rectification and filtering regulation circuit 83 connected to the secondary receiving resonant circuit 82, and a rechargeable battery 84 connected to the AC/DC rectification and filtering regulation circuit 83. The rechargeable battery 84 can be a built-in rechargeable battery or an externally connected rechargeable battery for receiving an AC signal that is transmitted from the transmitter circuit 91 and received by the receiver induction coil 81. The AC signal is subjected to resonance by the secondary receiving resonant circuit 82 and is further subjected to rectification and regulation by the AC/DC rectification and filtering regulation circuit 83 so as to convert the AC signal into electrical power. The electrical power is then stored in the rechargeable battery 84 so that the rechargeable battery 84 may subsequently supply the electrical power to each of the light-emitting elements 2.
The transmitter circuit 91 and the power source 92 can be connected in a wired fashion or a wireless fashion. The transmitter circuit 91 comprises an oscillation and frequency-division circuit 911 that is connected to the power source 92, a driving and amplifying circuit 912 connected to the oscillation and frequency-division circuit 911, a primary transmitting resonant circuit 913 connected to the driving and amplifying circuit 912, and a transmitter coil 914 connected to the primary transmitting resonant circuit 913, whereby the oscillation and frequency-division circuit 911 converts the electrical power supplied from the power source 92 into an AC signal, which is then amplified by the driving and amplifying circuit 912, and the amplified AC signal is subjected to resonance by the primary transmitting resonant circuit 913 to be transmitted by the transmitter coil 914 to the receiver circuit 8. Further, the transmitter circuit 91 may further comprise a feedback detection circuit 915 connected to the transmitter coil 914 and a control regulation circuit 916 connected to the feedback detection circuit 915 and the oscillation and frequency-division circuit 911, whereby the feedback detection circuit 915 feeds the AC signal transmitted by the transmitter coil 914 back to the control regulation circuit 916 to allow the control regulation circuit 916 to regulate the oscillation frequency of the oscillation and frequency-division circuit 911 in order to acquire the optimum result of resonance. The woven member 1 of the first embodiment shown in the drawings may adopt two ways to project the light emitting from the light-emitting elements 2. One is the formation of multiple holes 110 in the body 11 as shown in the drawings, and light emitting from the light emission section 21 of each light-emitting element 2 is allowed to project outside the body 11 through the holes 110. The light emission sections 21 that are exposed outside the body 11 are covered by a waterproof layer 14 (such as a waterproof polymerized material) in order to improve water protection and sealing thereof. The other way is using a weaving fashion of variable density (not shown) to make the woven member 1, whereby the body 11 has a lower density of weaving to allow light emitting from the light emission sections 21 to project through large gaps present in the weaving of the body 11.
As such, mounting the wirelessly connectable light source to an article through sewing, welding, adhesively bonding, or weaving can be realized by simply attaching the extension section 12 of the woven member 1 to the article by sewing, welding, adhesively bonding, or weaving. This completely overcomes the drawbacks of the conventionally known techniques.
Further, through proper coupling between the charging device 9 and the receiver circuit 8 (the charging device 9 and the receiver circuit 8 being coupled together through clamping in the drawings), the power source 92 is allowed to supply electrical power to the transmitter circuit 91, which converts the electrical power into an AC signal that is then transmitted by the transmitter coil 914 of the transmitter circuit 91 to the receiver circuit 8, so that the receiver circuit 8 can be charged to allow the rechargeable battery 84 to supply electrical power to each of the light-emitting elements 2, thereby facilitating the convenience of use.
Further, the wirelessly connectable light source according to the present invention further comprises a control circuit 6 and a switch 61, whereby the control circuit 6 and the switch 61 are electrically connected to the conductor 3. The control circuit 6 and the switch 61 are arranged inside the woven member 1. The control circuit 6 controls the fashion of light emission of the light-emitting elements 2 (such as regular light emission, flashing, or lighting with various brightness). As such, the wirelessly connectable light source according to the present invention is capable of supplying electrical power through the rechargeable battery 84 for energizing the light-emitting elements 2 to give off light and using the switch 61 to selectively light on or off the light-emitting elements 2 and may be further capable of controlling, through the control circuit 6, the lighting fashion of the light-emitting elements 2.
