Portable illuminators are useful in providing lighting to specific areas on a temporal basis. Certain portable illuminators can be affixed to objects thereby eliminating the need for the user to hold the light in order to use the light emitted. An example of portable illuminator may be a book light. Book lights often have a clip for clipping to a book and a light extending from the clip. The light may typically be positioned when manipulated by a user. Portable illuminators such as book lights are normally used in low light environments.
One illustrative embodiment disclosed herein pertains to individual light heads that are removably coupled to one another. In this illustrative embodiment, an illuminating device has a first housing with a first light source therein and a second housing with a second light source therein. The illuminating device also includes a base that is configured to permit removable attachment to an article. The first housing and the second housing are connected to the base via a first neck and a second neck. The first neck and the second neck enable the first housing and the second housing to be adjustably positioned with respect to the base. The first housing and the second housing are also configured to be removably attached to each other such that the first light source and the second light source can form a unitary light source or be separately focused on one or more areas.
Another illustrative embodiment disclosed herein includes an illuminating device having first and second housings, each with a light source therein, and a base configured to permit removable attachment to an article. First and second necks are each attached at one respective end to the base and at the opposite end to one of the housings. The first and second housing are configured to be removably coupled to each other to enable movement of the first and second housing together when coupled, and to be individually manipulated when uncoupled.
Another illustrative embodiment disclosed herein includes an illuminating device having first and second housings, each with a light source therein, and a base including a battery operatively connected to the light sources, and a user-engagable control switch. Flexible first and second necks are each attached at one respective end to the base and at the opposite end to one of the housings. The respective necks enable the housings to be adjustably positioned with respect to the base and with respect to the other housing. An attachment system removably couples the first housing to the second housing.
Yet, another illustrative embodiment disclosed herein includes an illuminating device having a base, first and second housings, and first and second necks. Each of the housings includes a light source and a coupling element. The base has clamp for removably clamping an article there between. The first neck is attached at a first end to the first housing and at a second end to the base. The second neck is attached at a first end to the second housing and at a second end to the base. Each neck has a length between 3 and 10 inches, and enables its respective housing to be adjustably positioned with respect to the base. The coupling elements of the first and second housing selectively permit the coupling and decoupling of the first and second housing to each other, and thereby enable movement of the first and second housing together when coupled, and to be individually manipulated when decoupled.

Overall Device
The depicted illuminating device 100 includes a first head 110A, a second head 110B, a first neck 130A, a second neck 130B, and a base 160. The first neck 130A enables the first head 110A to be adjustably positioned relative to the base 160 and adjustably positioned relative to the second head 110B. Likewise, the second neck 130B enables the second head 110B to be adjustably positioned relative to the base 160 and adjustably positioned relative to the first head 110A. Each of the heads, 110A and 110B includes at least one illumination member, such as a light emitting diode (LED). When illuminated, each head inherently has illumination characteristics, such as the concentration, spread, and direction of the emitted light, formed in part by the number of its illumination members, their position relative to each other, and any lenses and secondary optics.
In the illustrative embodiments, the illuminating device 100 is provided with a head coupling system such that the first head 110A and the second head 110B can be removably coupled together. When the first and second heads 110A and 110B are coupled together, as is shown for example in
The removable head coupling system also enable the heads 110A and 110B to be separated or decoupled from each other as is shown in
While the arrangements of the illuminating device 100 shown in
The first head 110A includes a first housing 115A that has a first light source, and the second head 110B includes a second housing 115B that has a second light source. The light sources are schematically illustrated in
In an illustrative arrangement as shown in the figures, both of the first housing 115A and the second housing 115B include sections 112A, 112B that have light transmittable properties (hereinafter “transparent sections”). The sections 112A, 112B may be formed of translucent, transparent or semi-transparent/translucent material, such as a suitable plastic, depending upon desired preferences and may allow the light emitted by the illumination member or members 111A, 111B to transmit there through.
At least one light source 111A is located inside the first housing 115A behind the transparent section 112A. Additionally, at least one light source 111B is located inside the second housing 115B behind the transparent section 112B. If desired, the transparent sections 112A and 112B may be shaped, for example like a lens, to have optical properties to distribute or concentrate the light rays. Accordingly, when the light sources are on, light emitted from the light sources 111A, 111B transmits through its respective transparent section 112A, 112B to the illuminate an area according to its illumination characteristics.
Head Coupling Systems
As shown in
In the illustrative embodiment shown in
Additionally, as best seen in
In addition, a visual alignment system may be used. In one arrangement, the visual alignment system is located on the side of the housings 110A and 110B opposite from the illumination members 111A, 111B and transparent sections 112A, 112B. That is, if the heads 110A, 110B are manipulated so to emit light downward, each the top surfaces of the heads 110A and 110B include at least one visual alignment feature that extends to or adjacent its side near the adjacent head that provides a visual guide in helping the user quickly and properly align and couple the heads 110A and 110B. In one embodiment, this alignment feature is formed by surface ornamentation or a contrast of coloring or finishes. One example of the visual alignment features is shown in
The connection between the housings can be accomplished through the use of any desirable coupling method in lieu of a magnetic coupling system as previously described.
Alternatively, as shown in
The embodiments with the snap fit couplings can also include all of the components of the embodiment depicted in
The second ends of the necks 130A, 130B can be connected to the base 160 using any attachment arrangement discussed above for attaching the first end of the necks 130A, 130B to the heads 110A, 110B. If desired, and as is depicted in the figures, the external portion of the flexible necks 130A, 130B are coupled together prior to base 160 at location 131, 231 so that the two necks can be a single element for assembly purposes.
As previously described, the flexibility of the necks 130A, 130B enables the heads 110A, 110B to be adjustably positioned relative to the base 160. In an illustrative arrangement, the necks 130A, 130B are universally adjustable elongated flexible connecting structures. In this embodiment, the necks 130A, 130B lack predetermined fixed pivots and are not bound to a finite number of positions. In the embodiment depicted in
The necks 130A, 130B may each be composed of several arm links, a rolled strip, or a tube-like housing around a wire, as well as numerous similar connecting members known in the art to provide flexible movement in all degrees of freedom. In alternate embodiments, not shown, the necks 130A, 130B may be formed by two or more rigid or semi-rigid members connected by hinges or by a telescopic arm. By affixing the heads 110A, 110B with the light sources, to one end of the necks 130A, 130B and the base 160 including the clamp 120 to second ends of the necks 130A, 130B, heads 110A, 110B, the heads 110A, 110B and the base 160 may be moved relative to each other enabling an almost infinite number of positions of the light sources. The positioning of the heads 110A, 110B are universally adjustable relative to the base 160 and merely bound by the length of the necks 130A, 130B.
The necks 130a, 130b may be of any desirable length. In a first arrangement, the necks 130a, 130b are between 3 and 15 inches in length. In an alternate arrangement and as a subset of the first arrangement, the necks 130a, 130b are between 3 and 10 inches in length. In yet another arrangement and as a subset of the prior described arrangements, the necks 130a, 130b are between 4 and 8 inches in length.
As seen in
In the illustrative arrangement, the first member 121 and the second member 122 are pivotally coupled to each other. In the depicted embodiment, this coupling arrangement is achieved by providing a pivoting mechanism 128. The pivoting mechanism 128 can be formed of any of a number of conventional pivoting mechanisms including pins, pivots, hinges, spring assemblies, etc.
Clamp 120 also may utilize a biasing member 165 depicted in part in
The pivot arrangement preferably forms a pivot axis 163 about which at least one member pivots relative to the other. In the illustrative arrangement, the first member 121 can be said to pivot relative to the second member 122. The biasing arrangement is such that the one side of the clamping members 121 and 122 can be used to clamp an object there between in clamping region 166. The biasing force caused by the biasing member is sufficient to, in the absence of significant counterforces, clamp and retain a portion of an object between the members 121 and 122. The biasing force can be overcome by applying a counter-force at the side 167 of the first member 121, which is opposite from the clamping region 166 relative to the pivot axis/fulcrum 163, and the first member 121 will pivoted to open the clamping region 166.
The clamping members 121 and 122 are made from any number of materials that would be used by one skilled in the art, including plastics, metals, and other materials used for such components. While the general footprint shapes of members 121 and 122 in
In the illustrative arrangement, the light source is part of a lighting system that may also include electronic components used to emit the light including power sources such as one or more batteries, connecting circuitry conventionally used in light sources, especially portable light sources, and a controllable switching device, discussed below.
A battery compartment is operatively connected to the illuminating components (e.g. LED) within the heads 110A, 110B via the necks 130A, 130B so as to provide power to these components. As described earlier, the necks 130A, 130B may be configured to be flexed, rotated and moved in almost any direction. Accordingly, flexible wiring may be utilized within necks 130A, 130B to permit movement without obstructing electrical current flow to the heads 110A, 110B.
In an illustrative embodiment, the power source can be located in the base 160 and connecting wiring can extend through the necks 130A, 130B to couple the power source to the light sources. In this illustrative embodiment, the power source (e.g., the batteries) can be located in the base 160. The power source can be coupled to the applicable circuitry, switch, and light sources in the first head 110A and the second head 110B, through suitable wiring that can be routed through the first neck 130A and the second neck 130B to couple the power source to the remainder of the lighting elements.
In an illustrative alternative embodiment, these components may all be contained on or in the housings 115A, 115B. In one arrangement, the housings 115A, 115B, and more specifically the transparent sections 112A, 112B, may include the power source, electrical components and other structural components that affix or secure the aforementioned electrical components as well as other components within light source housings 115A, 115B. Components used in emitting light may be housed within or located on the light source housings 115A, 115B.
A controllable switching device in the form of a user engagable control mechanism 113 is included on the base 160 in the depicted embodiments. In the illustrated illustrative embodiment, the user engagable control mechanism 113 (e.g., depressible button) is located on an upper section of the base 160. However, the control mechanism can be located at any suitable location. For example, the user engagable control mechanism 113 can be located at a different positions on the surface of the base 160 such as on its side or the engagable control mechanism 113 can be located on the first housing 115A or the second housing 115B in the form of two switches controlling each light source independently or a unitary switch controlling both light sources.
In illustrative arrangements and as shown in
In lieu of the depicted depressible button, user engagable control mechanism 113, may be any of a number of switching mechanisms including switches, slide bars, toggles, and linearly slidable elements to allow the user to control light source housings 115A, 115B. For example, a user may interact with user engagable control mechanism 113 to adjust the brightness, permit intermittent light to be emitted, and turn the light source housings 115A, 115B “ON” and “OFF”.
The illuminating device 100 is generally operable with its heads in two alternative configurations. In the first configuration, as depicted in
As described herein, the illuminating device 100 may perform numerous functionalities. For example, the clamp 120 allows the illuminating device 100 to be affixed to numerous structures, enabling use of the illuminating device in locations that are often more difficult to illuminate and that lack adequate lighting. More specifically, clamp 120, in certain embodiments, may be used to clip or clamp onto a structure in the area of desired illumination. The clamp 120 may be used to affix the illuminating device 100 to countless surface and structures. The illuminating device 100 may also be hung, affixed directly to or placed beside, any area of intended illumination. For example, the clamp 120 may be clipped onto the cover of a book, the edge of a desk, onto a laptop or notebook computer, around a pole, or even the fold down tray of an airplane cabin seat, etc.
To affix the illuminating device 100 to a particular structure, a user may apply a force at the side 167 which is opposite the clamping region 166 relative to the pivot axis 163. The force may be applied at the location of the grip enhancing region. The force should be sufficient to overcome the pivotal biasing force urging the members 121 and 122 into a clamping position. In particular, the force may be exerted on both members 121 and 122, thereby causing the clamp 120 to have a modified position from a neutral/clamped position to a more open position. While still applying the illustrative squeezing force, a user may then position clamp 120 so that the interior surfaces of the members 121 and 122 border the surfaces of the structure to which the illuminating device is to be affixed. Once interior surfaces border the structure the illuminating device is to be affixed to, the user then releases clamp 120, thereby eliminating an opposing force that was countering the biasing force. The biasing force will then cause clamp 120 to clamp onto a given structure at clamping region 166.
As described, illuminating device 100 may be utilized, among other things, as a book light. In such use, illuminating device 100 may be decorated and designed with numerous aesthetic features, including decorative shapes, contours, shadings, colors or designs. These decorative features, that may be placed on, or formed as part of, light source housings 115A, 115B, clamp 120 and/or necks 130A, 130B to name a few components and may encompass a seemingly limitless list of decoration, and thus are not described in specifics herein. As previously described, components of illuminating device 100 may have varied characteristics depending on the desired functionality and appearance. For example, each of light source housings 115A, 115B, clamp 120, and necks 130A, 130B may have varied physical, material, and functional aspects. Similarly, the orientation or manner of connection of heads 110A, 110B, necks 130A, 130B and base 160 may be varied.
Three or More Two Heads with Lighting Units
The embodiments of
In such an arrangement, each coupling of any two or more heads results in the capability of adjusting those coupled heads together as a single illumination unit. The coupled heads would exhibit the combined illumination characteristic according to a predetermined illumination characteristic formed by the combination of those heads. Any uncoupled head, including all of the heads when they are all uncoupled, enables the user to separately adjust the position and the angles of the heads to illuminate desired areas. With three or more heads, it is therefore possible to have all the heads coupled together, a selected two of the heads coupled together, or all the heads uncoupled. Any of the illustrative head coupling systems described and/or depicted herein can be used for this coupling system.
Additionally, this embodiment includes features as has been described with respect to the other disclosed embodiments. For example, in one arrangement, the illuminating device 500 includes a visual alignment system formed by regions 519A, 519B, and 519C on the top surfaces of the housing 515A, 515B, and 515C to aid in the coupling process. Further, the illuminating device 500 preferably includes a control and power system and is operated the same or similar to the manner that was described with respect to the other embodiments. For example, an user engagable control mechanism 513 on the base 560 may be used to control turn the illumination members on the heads on and off, either all together, or an cycle through various states of all ON, all OFF, and the combinations of the lights being ON and OFF.
While the invention has been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques. For example, the embodiments depicted in the figures reflect illustrative industrial designs. However, there are numerous variations of industrial design that embody elements and combinations of elements of the disclosure. Thus, the spirit and scope of the invention should be construed broadly as set forth in the appended claims.
