This invention relates to an illumination device which is mountable through an aperture in a sheet of material, which, for example, is an object of clothing, such as a hat, shirt or jacket, for example an incandescent lamp, light emitting diode (LED) or an array of LEDs within a housing which may be mounted through a hole in an article of clothing, to provide lighting for a wearer.
2. Description of Related Art
Portable lights have been used in the past with garments, including lights attached to headgear or other garment articles for illumination purposes. Based on its usage such as in a hat (or on a garment), the size, weight, weight distribution and access to the battery pack become characteristics that affect the overall usability of the portable light.

In headwear, any torque due to unbalanced masses may lead to sagging or slipping of the gear or object in which it is mounted out of alignment. Likewise, large batteries or other massive structures are undesirable. Protruding portions of the system, such as battery housings, lamp reflector housings, and the like, on the inside of a clothing object, may be uncomfortable. Adjustment opportunities for the beam axis on a clothing object has been limited in prior designs.
Various prior art light modules designed to clip or otherwise attach to clothing or headgear can become separated during use, or light modules attached to a head strap, may not stay in place or may be cumbersome and uncomfortable.
Another problem faced by the art is the switching mechanism, particularly in hat embodiments where the switch may be unseen by the user when sought to be actuated.
SUMMARY OF THE INVENTION
The present invention provides an illuminator, which preferably forms a light beam which may be aligned with the field of view of the wearer, which is attached through an aperture by a clip or other means, to a sheet of fabric, which is typically an article of clothing, such as a hat, shirt or jacket.
The illuminator preferably has a power source, which may be within an integral housing with the light emitter, or separated from the light emitter, for example connected through a cable.
The illuminator may be switched on and off, in certain embodiments, by manipulation of an illuminator subhousing with respect to a supporting structure, for example by means of a switch, rotation, or altering an inclination or axial angle of the subhousing.
In one embodiment, the design has a low profile, with the batteries placed unobtrusively in a compartment next to the body of a wearer, within an article of clothing, and the entire housing in this compartment is only slightly larger than the thickness the battery. Therefore, the illumination control is preferably not on a hidden portion of this compartment, since this may make actuation difficult. On the other hand, the illumination emitter is generally visible and available, making a control associated with this component attractive. In some instances, in spite of the generally forward field of illumination of the illuminator, it is desired to adjust the direction and/or breadth of the field of illumination, and thus some embodiments provide an adjustable axis of illumination and/or field of illumination.
The illumination source may be, for example, an incandescent bulb, e.g., a 3-4.5V halogen lamp, an LED or LED cluster, e.g., a set of white LED's to provide appropriate illumination, an electrical discharge and/or fluorescent bulb, a fiber optic illuminator, or other source.
The power source is preferably a pair of 1.5 V AA or AAA batteries, but LED illuminators and LED clusters particularly lend themselves to 3 V lithium coin cells, e.g., type CR2032, CR2430 or CR2450 batteries. This permits direct drive of the LED or LED cluster from the unregulated output of the batteries, simplifying the circuit. Of course, a regulated voltage design could also be employed. Preferably, a voltage-converter or other driver circuit is employed to drive a set of LEDs. This decouples, in part, the drive voltage of the LEDs from that directly available from the power source. Preferably, the drive circuit is integral with the circuit for mounting the LEDs, providing a two wire interface from the power supply to the LED support and driver circuit. Likewise, it is preferred that the subhousing holding the LED support and driver circuit be switched based on an intermittent supply of current through one or both of the supply wires, effecting a switch mechanism.
In preferred instances, the aperture in the article of clothing is specifically adapted to hold the illumination device, for example a circular hole, a keyed generally circular hole, or a reinforced slit (e.g., similar to a buttonhole) which may have reinforced edges. In other embodiments, an illuminator subhousing is located external to the article, while the power supply subhousing is located internal or external to the article. In the case where the components are separated, the two components may be connected by one or more extensions, which provide electrical connection and mechanical support. In the case where both are collocated, the perforation provides mechanical support only. The aperture may be, for example, a button hole, adapted to pass a connecting member therethrough. The illumination device may therefore be clamped to the material surrounding the aperture, to hold the illumination device securely in place.
According to a first embodiment, the power supply subhousing has a pivot with a set of slip ring electrical connections, to support the illuminator subhousing which extends through a circular aperture in the clothing. A clamp is provided which extends around the illuminator subhousing, which holds the power supply tightly against the fabric of the clothing. The switch mechanism is integrated into the slip ring connector, which in one position, e.g., above vertical, is open circuit, but in other angles forms a complete circuit which illuminates the device. In general, a working position for the illuminator is one in which the illuminator subhousing is inclined somewhat below vertical. This embodiment allows the angle of the light beam to be adjusted to any position below vertical during operation. Alternative methods for switching power on/off include a separate mechanical switch such as a push button, slider switch or rotation of the exterior part of the illuminator subhousing. An alternate embodiment employs a ball and socket, in which a wire or wire extends up a hollow shaft to provide an electrical path with another wire or a conductive shaft. In this case, the switch may be operated by mechanical contact with a leaf switch mechanism based on an angle of the ball and socket (or mechanically linked structures) or a separate switch element. Alternatively, the ball and socket mechanism may serve as a switching mechanism by placing contacts in the ball and socket in a configuration such that contact is opened and closed by rotating or angling the light module so the contact on the ball makes or breaks connection with the contact in the socket. This ball and socket design allows the light beam angle to be adjusted in two dimensions.
According to a second embodiment, both the power supply and illuminator subhousings are provided external to the article of clothing, and these two components may be integrated into one unit. In this case, similar to the second embodiment, a set of standoffs are provided which extend through perforations in the clothing, and attach to a retaining clip. In this case, of course, the standoffs are not electrically operative.
According to a third embodiment, a fiber optic or fluid optic conduit is provided, wherein an illumination source is internal, disposed within a housing, and a conduit or fiber is provided to selectively guide the light where needed. The system may thus make use of fiber optics and/or optic conduits, e.g., fluidic light guides (liquid core light guide), which permit the illuminator to be removed from the physical location of the desired illumination point. For example, a fluidic light guide may be provided from an internal light source, such as a high intensity LED, wherein the fluidic light guide may extend within a gooseneck structure to maintain its desired orientation after positioning. The advantage of such an embodiment can be a minimal protrusion of the light source on the outside portion of the clothing item.
According to one implementation of the invention, an optional power socket is provided to power an auxiliary device, such as an MP3 player or cell phone. Further, the clothing may be provided with an optional pocket for holding the auxiliary device. For example, a hat is provided with an illumination device in the front thereof. Internally or externally, a socket is provided which taps the power from the power supply, e.g., 3VDC, which passes through a cable to the auxiliary device. The power supply may include rechargeable batteries, in which case the same or a different connector may be used for recharging. Likewise, the power supply may be used to charge rechargeable batteries in the auxiliary device. The auxiliary device may be maintained within a pocket or recess, or beneath a band, in the hat.
According to another implementation of the invention, a camera and/or a microphone may be mounted in addition to, or in place of the illuminator, or these may be concealed within the illuminator casing. This camera and/or microphone units may be wireless for sending and remotely saving video and audio taken by the wearer, or may be saved within a memory module located within the illuminator casing, power supply casing or disposed in a location on the article of clothing or hat. The illuminator is preferably aligned with the lens axis, so that the illuminator effectively illuminates the scene. In some cases, the illumination may be infrared, and the camera responsive to infrared.
One embodiment provides a portable light that can be easily attached to a textile or fabric (found in a hat or other garment) that includes a housing for storing batteries (either rechargeable or disposable) and a separable lighting unit that includes an illumination source, for example a light bulb, a light on/off switch, the reflector, a reflector cover and a fabric clamping unit having at least one prong that clamps into the battery housing for securing said battery housing and light to said textile or fabric. The housing may also contain a connection for receiving power from and/or providing power to an external device.
A portable light unit is provided that can be readily secured to a textile or fabric such as a hat comprising a an illuminator sub-housing separably connected to a power supply casing which may contain at least one battery or be connected to a power supply such as battery case.

In normal operation, the lighting unit is secure at all times, regardless of the normal forces on the clothing article. The power supply may be accessible from the inside of the article of clothing for changing batteries when necessary.

PREFERRED EMBODIMENTS OF THE INVENTION
FIGS. 1A1 through 5C show embodiments of the invention where the illuminator casing is attached to the power supply casing and the light unit is located on the inside of the article of clothing or hat when mounted. This embodiment provides that the entire light unit remains assembled as one piece, the illuminator casing itself projects forward of the power supply casing and the front surface of the article of clothing or hat through a circular aperture. Moving the illuminator casing to the outside enables a more efficient design of the power supply casing, reducing its thickness and improving comfort for the wearer. This design also enables the direction of the light beam to be adjusted to any vertical position in one variation and in any horizontal or vertical direction in another variation. This is particularly useful when the wearer is facing another person while the light is in use, because the focus of the light beam can be moved away from shining directly in the other person's face.
Referring to FIGS. 1A1, 1A2, 1B1, 1B2, 1C and 1D show various embodiments of the lighting unit wherein the position of the light beam can be adjusted by moving the illuminator casing vertically, and illustrate different designs for connecting the illuminator casing to the power supply casing. In this embodiment, the illuminator casings 82a, 82b, 82c and 82d are attached to and moved relatively forward from the power supply casing 84a, 84b, 84c and 84d. 
FIGS. 1A1 and 1A2 show a variation of a lighting unit 200a wherein the illuminator casing 82a has a yoke 86 which pivots about a pin 88, which is passed through the yoke 86 and a hole in the retainer arm 104 which is part of and is disposed within the depth of the power supply casing 84a. FIGS. 1B1 and 1B2 show a variation thereof, having a lighting unit 200b wherein the illuminator casing 82b has a yoke 90 which pivots about a pin 92, which is passed through the yoke 90 and a hole in the retainer arm 104 which is part of, and disposed forward from the power supply casing 84b. FIG. 1C shows a variation, having a lighting unit 200c wherein the illuminator casing 82c has a pin 94 passes through a retainer arm 108 located on the back of the illuminator casing 82c which pivots about a yoke 96, which is part of the power supply casing 84c. The main difference in this variation is that the yoke 96 is part of the power supply housing 84c instead of being part of the illuminator casing 82c as in FIGS. 1A1, 1A2, 1b1 and 1B2. FIG. 1D shows a variation having a lighting unit 200d wherein the illuminator casing 82d pivots about a pin 98, which is mounted within the power supply casing 84d. In each case, power may be provided to the illuminator from an internal source, through a set of sliding contacts, or through a cable.
FIGS. 2A, 2B and 2C shows the lighting unit 200b with various switching schemes for illuminator casings 100a, 100b, and 100c, which are mounted on a power supply casing 82b through a pin 92, which is inserted through the yoke 102 and the retainer arm 104. A plate 106, having prongs 20, engages slots 14a, and is used to clamp the light unit 200b to an article of clothing or hat providing a connection and support during use. The illuminator casing 100a is switched by a mechanism triggered by the angle of the illuminator casing 100a on the retainer arm 104. For example, each lateral portion of the yoke 102 has a metallic conductive portion 112, which forms a circuit when it overlays a metallic portion 108, but when moved out of position, the circuit is open. FIG. 2B shows a mechanical switch 114 on the surface of the illuminator casing 100b. FIG. 2C shows that the switch may be operated by twisting a portion 116 of the illuminator casing 100c. 
FIGS. 3 and 4 show the placement of a lighting unit 200a or 200c on a baseball cap 116. In this case, the power supply casing 84a or 84c is placed within the inside front of the baseball cap 116, with the illuminator casing 82a or 82c attached to the power supply casing through the yoke 102 and retaining arm 104 by the pin 92. The illuminator casing 82a or 82c extends through a circular aperture 118 in the baseball cap 116, which, for example, has a cut or reinforced edge, and is clamped in place with plate 106 which has an aperture sufficiently large for it to pass over the illuminator casing 82a or 82c and prongs 20 to clamp into and secure the lighting unit 200a or 200c to the baseball cap 116. Of course, the baseball cap 116 can be any article of clothing or type of hat.
FIGS. 5A, 5B and 5C show a further embodiment of the invention. In this case, a lighting unit 210 comprises an illuminator casing 122, with multiple LED illuminators 124, and switch 114. The illuminator casing is mounted to the power supply casing 126 on a ball 128 in socket 130 mount, to provide freedom of movement in both horizontal and vertical directions, with respect to the power supply casing 126. In this case, the ball 128 in socket 130 provides a first conductive path to the LED illuminators 124, while a wire 132 passing through an aperture in the ball 128 and shaft 134 provides the current return path. Alternatively, the design could employ two wires or the ball 128 and socket 130 could each have two connectors. If the latter method of two connectors is used, the current could be switched by rotating the illuminator casing 122 in the ball 128 and socket 130. The power supply casing 126 is affixed to an article of clothing or other sheet with the plate 106 having prongs 20, which are inserted into slots 136. As with the prior embodiment, the plate 106 has an aperture sufficiently large for it to pass over the illuminator casing 122, and article of clothing or other sheet has an aperture through which the prongs 20 and illuminator casing 122 pass. In this embodiment, the illuminator casing 122 is shown with 5 LEDs, however, any number, type or color light may be used. If multiple LEDs are employed, an odd number in a symmetric arrangement, such as 1, 3 or 5 LEDs are preferred.
The embodiments shown in FIGS. 1A1 to 18C particularly lend themselves to be adapted for a single LED and lens configuration designed to emit an intense and broad beam of light. For example, an illumination module similar to that used in the Power Chip LED Flashlight sold by Coast products of Portland Oreg. may be used. The illuminator components of this flashlight comprise a power circuitry, a single LED and a prism reflector lens. The LED is mounted on a driver circuit board which is disposed behind the LED, and the prism reflector is placed over the LED and serves to intensify and focus the beam of light emitted by the LED. Similar components can be used within the illuminator casing to provide a high intensity light beam. Alternately, the LED and prism can be disposed in the illuminator casing and the powering circuitry contained in the power supply casing and connected by wires or other electrical connectors.
FIGS. 6 and 7 show another embodiment in which both the power supply casing 14 and illuminator casing 50 are integrated into one piece which is mounted on the outside of the article of clothing or hat. This embodiment enhances wearer comfort by minimizing the portion of the assembly located on the inside of the article of clothing or hat next to the wearer. Instead of having the prongs 20 extending inward toward the wearer of the article of clothing or hat, a set of prongs 60 extend forward from a mounting 62 located on the inside of the article of clothing or hat 66, to support a lighting unit 64 in front of the article of clothing or hat 66. Advantageously, the prongs 60 engage pivots 68 to allow redirection of the beam of light passing through the lens 52. The rotatable ring 56 can be used as a power switch and/or to focus the pattern of the light beam, or a separate power switch 58 can be used.
As shown in FIG. 7, the cap 66 has a pair of reinforced slot like apertures 70 that resemble button holes corresponding to the prongs 60, which support the lighting unit 64 facing forward. In this embodiment, at least one battery is housed within the lighting unit 64.
As shown in FIG. 8, the same lighting unit 64 may be supported by other types of clothing articles, such as shirt 72 having sets of apertures 74 and 76, in different locations, such as a pocket or on a shoulder.
FIG. 9 shows an embodiment with a different lighting unit 78, which for example uses LEDs 80 and a lens or lenses to magnify and/or focus the LED 80 light beam. The light beam may be switched to different intensities or colors, and other optional lights or LED's 59 can be used to indicate the status of the system. With this embodiment, as with others, other electronic devices may also be housed within the same lighting unit 78 module, for example a camera or video camera, audio recorder, or the like. Indeed, in some cases, the lighting function itself is optional.
FIG. 10A shows yet another embodiment wherein a light unit 220 comprises a power supply casing, driver circuitry, an internally disposed illuminator, which in this embodiment comprises three LEDs 226, and a fiber optic, guided light optic, or fluid optic conduit 228 which is flexible at its outward end to enable the position of the light beam to be adjusted about both the vertical and horizontal axis. Preferably, a goose neck structure is provided to retain the desired position. The light unit 220 is attached to the inside of an article of clothing, in this case a baseball cap 250 by a cloth fastening system such as Velcro (not shown). Although in this embodiment, a cloth fastener is a preferred method for connecting the light unit 220 to the article of clothing, the clip and prong method used in other embodiments of the invention can also be employed. The outward end of the fiber optic, guided light optic or fluid optic conduit 228 extends to the outside of the baseball cap 250 through a small aperture (not shown) which may be reinforced if desired.
In this embodiment as shown in this FIG. 10A, the power supply 251 is located separately from the light unit 220, and connected by electrical wires 230. Alternate embodiments shown in FIGS. 10B and 10C employ type AAA batteries 240 in the same housing, and coin cell batteries 242 respectively. In this embodiment, the light source 226 is internally disposed within the power supply housing 222, and the fiber or conduit 228 selectively guides the light from an internal light source 226 to where needed. The advantage of this embodiment is a small, light and compact size which is more comfortable for the user, capable of being attached with cloth fasteners because if its reduced bulk and light weight, and which provides for a minimal aperture size and minimal protrusion of the fiber or conduit 228 on the outside portion of the baseball cap 250 or other clothing item. While this embodiment uses a flexible fiber/fluid optic, in an alternate embodiment the illuminator can be mounted on the end of a flexible shaft and receive electrical power from the power supply casing by electrical wires passing through said shaft.
It should be noted that throughout the figures and descriptions, the power supply casings contain space for batteries; however, in variations the batteries can be located separately from the power supply casing, and connected with wires which may be permanently fixed or detachable using a wire harness plugs or other methods commonly used to connect wires.
The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
