The disclosure relates to an illumination device, and more particularly to an illumination device attached to a computing device, especially a handheld computing device such as a smart phone, to facilitate video calls, teleconferences, other camera-related processes, and other applications conducted with the computing device requiring optimized illumination.
Computing devices, especially handheld computing devices, have undergone explosive development in the past two decades. Here, computing devices refer to but are not limited to: desktop computers, laptop computers, and handheld computing devices such as but not limited to smart phones such as iPhones® or Android® phones, computing tablets such as iPad®, Personal Data Assistants (PDAs), and other devices that are relatively small and light and are equipped with basic computing and internet connecting capabilities. Computing devices are playing more and more significant roles in people's work, entertainment, and communications.
Most of the computing devices nowadays are equipped with cameras. In many cases, especially for handheld computing devices, there are two cameras, one on the front side of the device—the same side with a general display screen, and the other one on the back side. One fairly widespread usage of the computing devices is video call, or video conference in some instances, during which both video images and audio signals are transmitted and received. Most likely the video images are captured with the front side camera, allowing a user of the device to see the display on the device and be visible at the same time. Video calls enable the callers to hear and see the other person at the same time. Combined with the mobile capacity of the handheld computing devices, video calls strongly facilitate communication and interaction between the parties.
One drawback of the video call conducted on a computing device, however, is the unpredictable and often far-from-ideal illumination, which renders the video call less attractive or even impossible to proceed. This problem is especially acute for the handheld computing devices. Due to their mobility, video calls conducted with handheld computing devices may be carried out in some locations never been conceived previously. Instead of a nicely illuminated conference room, a user of a handheld computing device may find himself/herself in a car, in a dark room, or in some places with weak or impossible-to-adjust light, making it impossible to show the user's image properly. The current disclosure addresses this problem by providing an illumination device that may be attached to a computing device and enable a user to have manageable light for his/her video call or video conference. In addition, the illumination device introduced by the current disclosure may have numerous additional applications that would provide significant convenience and greatly improve the user experience of the computing device.

Various devices are known in the art. However, their structure and means of operation are substantially different from the present disclosure. The other disclosures also fail to solve all the problems taught by the present disclosure. At least one embodiment of this disclosure is presented in the drawings below and will be described in more detail herein.
The current disclosure discloses an illumination device to be used with a computing device, especially a handheld computing device. The illumination device comprises: a light source; a power connecter, and an attachment assembly affixing the light source to a computing device. The illumination device disclosed by the current disclosure would significantly improve the experience of video calls, video conferences, picture-taking, and other camera-related or unrelated activities conducted by a computing device.
In one embodiment, an illumination device is disclosed that is capable of being removably coupled to a computing device. The illumination device includes a case having a front side and a back side opposite the front side. The case is sized to receive the computing device in a receiving area of the front side. The illumination device also includes at least one light source disposed on at least one of the front side or the back side of the case. The at least one light source is covered by at least one light cover, where the at least one light cover modifies an appearance of light produced by the at least one light source. The illumination device also includes a light control mechanism configured to change at least one of an operative state or an intensity of the at least one light source and a power source operably coupled to the at least one light source.
In one embodiment, an illumination device is disclosed that is capable of being removably coupled to a computing device. The illumination device includes a case sized to receive the computing device in a receiving area and at least one light source disposed on the case. The at least one light source is covered by at least one light cover, where the at least one light cover modifies an appearance of light produced by the at least one light source.

In yet another embodiment of the present disclosure there is an illumination device for a computing device, the illumination device having an attachment assembly capable of being removably coupled to the computing device, wherein the attachment assembly has a front surface, a back surface, a top surface, a bottom surface, and at least two side surfaces, wherein each of the at least two side surfaces have at least one light rail comprising a light cover and a plurality of light sources, the at least one light rail extending past the front surface, and wherein the attachment assembly has a recess sized to receive the computing device; at least one touch sensitive button disposed on the back surface of the attachment assembly, wherein the at least one touch sensitive button changes an operative state of the plurality of light sources; a rechargeable battery contained within the attachment assembly and being operably coupled to the plurality of light sources; a charging port located on the bottom surface of the attachment assembly; at least two securement structures capable of retaining the computing device in the attachment assembly, wherein the at least two securement structures are lateral extensions extending from a separate light rail, and wherein the computing device is released from the at least two securement structures by flexing of the attachment assembly.
As indicated above, “computing device” used here is a broad concept and it refers to but is not limited to: a desktop computer, a laptop computer, and a handheld computing device such as but not limited to smart phones such as iPhone® or Android® phones, computing tablets such as iPad®, personal data assistants (PDAs), and other devices that are relatively small and light and are equipped with basic computing and network connecting capabilities. Since the usage of the present disclosure is more clearly demonstrated on handheld computing devices, the discussions will be focusing on such devices. However, it should be clear that the illumination device disclosed here may also be implemented to desktop and laptop computers and have significant beneficial effects.
With the implementation of front and back cameras, handheld computing devices may be used in ways that could not be conceived before. As indicated above, one of the applications is video call or video conference that allows the users to see and speak to one another at the same time. In most cases, a user is holding the handheld computing device with the front of the handheld computing device, defined as the side having a display screen, facing the user. The front camera, the camera on the same side as the display screen, is thus capable of capturing the image of the user, especially the image of the user's face. Through its networking capacities, the handheld computing device transfers the captured image, as well as audio signals recorded, to the other party/parties engaged in the video call or video conference.
Such a communication experience, however, may be spoiled by weak or improper lighting. When it is too dark, it is very difficult for the front camera to capture a usable image of the user, making a video call less attractive. Moreover, many other camera-related processes and applications conducted with a handheld computing device may have similar requirements for optimized lighting conditions. One simple example is taking a photograph or video recording with the handheld computing device, either of the user himself/herself, or of another person, or of any other scene or subject. When the ambient light is too weak, it may ruin the results of the picture or the video. Another example is the “mirror” application for handheld computing devices, with which a user may see his/her own image in the display. Poor ambient light conditions also harm the usage of such applications.
The current device addresses the problems listed above by attaching a light source, preferably a plurality of light-emitting diodes (LEDs) to the handheld computing device, allowing the light source to illuminate the user, especially the user's face, enabling the front camera or the back camera to capture an optimized image of the user or any other subject and facilitate the video call, the photo or video capturing, the “mirror” application, or any other camera-related experience.
Moreover, with the basic design, there may be numerous variations that would provide different kinds of embodiments of the illumination device to satisfy different needs for applications and users. Some of the applications do not even have to be camera-related because the illumination device disclosed herein may also have signaling capacities besides the functions to provide lighting.
The light source, as suggested, is preferably LED lights. However, the light source may also be other lights such as compact florescent lights (CFL) or electroluminescent light. In particular, electroluminescent light using algae-based wire and panels, such as the light based on RILI technology, may be incorporated as the light source in the current device. In addition, sometimes it is desirable to make the lights adjustable in terms of luminous intensity, viewing angles, and diffusion. The lights may have color either by using color lights or with the addition of a color cover. In general, implementing more adjustability may allow the illumination device to provide lighting for one or more persons and for various purposes. It may also enable the illumination device to flash, to demonstrate different patterns, and therefore satisfy different needs.
There may be a power source, separate from the power source for the handheld computing device. The power source may be connected to the lights through a power connector, providing energy needed for the illumination. The power source may be one or more batteries, such as the regular AAA zinc-carbon or alkaline battery, or any other type or size that may fit the needs in terms of energy needs or physical accommodation. The battery may be disposable or rechargeable, allowing flexibility as to cost-effectiveness and convenience. The battery may be connected to both the illumination device and the handheld computing device, providing energy to both devices, serving as a backup or extra power source to the handheld computing device. On the other hand, it is also possible to simply connect the light source to the handheld computing device and allow the light source to use the power of the handheld computing device, reducing the size and weight of the illumination device and making it more portable.
The illumination device includes an attachment assembly that affixes the light source to the handheld computing device. The attachment is preferred to be non-permanent, so that the lights may be added or removed as the user desires. The attachment assembly may take many forms. For example, it may be a flat case with an indentation to enclose a power source and power connector, while also having a recess or docking place for the handheld computing device to attach. The current disclosure encompasses all kinds of attachment assemblies that allow convenient connection between the lights and the handheld computing device. Moreover, the attachment assembly may serve additional purposes such as supporting the handheld computing device in an easy-to-view position, allowing a user of the handheld computing device to watch the device in a hand-free mode. In addition, more complex attachment assembly may include structures that allow the illumination device to be further integrated with the handheld computing device in terms of synergetic control and data sharing.
The illumination device may further comprise an external switch that allows the user to turn the lights on and off. However, it is possible, especially when the illumination device is sufficiently integrated with the handheld computing device, to use the buttons, switches, and menus on the handheld computing device to control the lights.
As indicated above, the illumination device may be used to facilitate video calls or video conferences or to enhance other camera related functions of the handheld computing device. In such a case, the illumination device taught by the current disclosure may enhance such experiences by providing additional and well-controlled illumination.
In addition, with further connection between the lights and the handheld computing device, the lights of the illumination device may serve as indicators for a handheld computing device's status or as signals for the applications being used on the handheld computing device. For example, the lights may flash or light up when there is an incoming call. Or the lights may change in lighting pattern, luminous intensity, or color when the user is speaking on the handheld computing device or when certain music or game is being played.
Also in the purview of the current disclosure is a series of computer programs or applications that may be used to control the illumination device. For example, a basic version of such a program would be able to adjust the luminous intensity, viewing angles, lighting pattern, and/or color of the illumination device. A more advanced program would allow the illumination device to synergize with the status of the handheld computing device, such as an incoming phone call. Still another advanced program may integrate the illumination device with another application so that the lights are partially controlled by the application.
In general, the illumination device is designed to be small, portable, versatile, energy efficient, durable, and fully compatible with the handheld computing device, or more generally, the computing device, that is to be used with the illumination device.

The preferred embodiments of the present disclosure will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.
Reference will now be made in detail to embodiment of the present disclosure. Such embodiments are provided by way of explanation of the present disclosure, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.
As indicated above, the handheld computing device 100 is defined broadly. In
The image 140 here in
The LEDs, as shown in
The LEDs may have different technical specifications and dimensions. In general, the LEDs should be small and match the handheld computing device 100 and the intended usage. Standard T1 LEDs, T1-3/4 LEDs, various kinds of surface mount LEDs, miniature LEDs, mid-range LEDs, high-power LEDs, LED panels, LED modules, and other kinds of LEDs may all be possible choices for specific uses. Some special types of LEDs may be used for special effects.
For example, single wave length LEDs may be used to light therapy. In general, the LEDs may use electricity ranging from 0.1 mW to 50 W, with current ranging from 0.1 .mu.A to 1 A and voltage ranging from 0.1 mV to 250 V. The LEDs may emit white light or color light with particular wavelengths. In a preferred embodiment, the LEDs emit light of warm color temperature, i.e. 2400 Kelvin.
The power source 30 here in
In
The power source 30 is designed to provide power to the LEDs. When the voltage or current provided by the power source 30 is insufficient to power the LEDs, it is possible to include a regulator circuit, such as a buck-boost converter, to enhance the output from the power source and ensure that the LEDs are adequately supplied. Such regulator circuits are well-known in the arts. In addition, the illumination device 1 may further comprise a battery meter that measures the battery life and informs the user to change batteries when necessary. The technology for such battery meter is also well known in the arts.
In addition to providing power to the LEDs, the power source 30 may serve as a backup power source to the handheld computing device 100. With proper connections between the handheld computing device 100 and the illumination device 1, both in terms of control circuitry and electricity connections, it is possible that the power source 30 may be used to directly provide energy to the handheld computing device 100, enabling a longer overall battery life and providing more flexibility. When the power source 30 is rechargeable, the handheld computer device 100 may also be recharged, enabling a convenient solution for supplying power to both the illumination device 1 and the handheld computing device 100.
It should be noted that
In
It should be noted that the switch 70 may have different designs to accommodate different needs. The switch 70 may be mechanical, electrical or logical. In its most simple form, switch 70 may turn on and off all the LEDs without any other adjusting capacities. However, switch 70 may also be designed as a dimmer that dictates the brightness, or luminous intensity of the LEDs in a certain range. One possible design is that the switch 70 may control mechanical means of adjustment such as articulating lens or lenses covering the LEDs, allowing for change of illumination intensity. To enable the switch 70 to perform such a function, some well know circuits such as a potentiometer may be included in the illumination device. Moreover, switch 70 may have a more complex design to control the individual, sub-sectional, or whole group of LEDs' luminous intensity, viewing angle, color, and lighting patterns.
The current disclosure discloses an attachment assembly that affixes a light source 10 to a computing device. In the embodiment shown in
The case 55 may be a one-piece structure or have a multi-piece design for more flexibility and convenience. In addition to attaching the light source 10 to the handheld computing device 100, the case 55 may also provide physical and hygienic protection to the handheld computing device 100, preventing it from damages due to physical impact. The case 55 may be made from materials such as but not limited to: rubber, leather, faux leather, wood, marble, artificial stone (e.g., Silestone®), graphite (e.g., carbon fiber), metal (e.g., aluminum) sheet or foil, or plastic such as, but not limited to, polyethylene terephthalate (PET), polyethylene (PE), high-density polyethylene, polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), low-density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), high impact polystyrene (HIPS) and polycarbonate (PC), or some combination thereof. The case 55 may be made of one kind of materials, or different parts of the case 55 may be made of different materials, ensuring optimized protection and feel. In some examples, case 55 may be designed to be flexible. In some examples, case 55 may include light source(s) 10 comprising one or more flexible LED strips, a flexible printed circuit board and/or a flexible power source (such as a flexible battery).
It should be noted that the “snap-in” design is not the only form of attachment to connect the handheld computing device 100 to the case 55. For example, the case 55 may comprise two pieces of cover, either or both may be slidably connected to the handheld computing device 100. It is also possible that the handheld computing device 100 may be fastened to the case with other means such as pre-positions screws, hook-and-loop fastener, riveting, or any other kind of mechanisms allowing a secure attachment. Preferably, the case 55 is removably attached to the handheld computing device 100, allowing easy detaching for higher level of flexibility. However, it would also be acceptable to make the case 55 a permanent fixture of the handheld computing device 100, allowing high level of integration between the handheld computing device 100 and the illumination device 1.
The LEDs may be mounted to the case 55 by any means that allow secure attachment. The LEDs may be welded, screwed, riveted, glued, co-molded, or in any other way linked to or inserted into the case 55. Necessary structures, such as prepositioned magnets or hook-and-loop fasteners, or snaps, may be employed to fasten the LEDs to the case 55. In general, the LEDs may be connected to the case 55 in a permanent or removable manner. Moreover, the approach to connect the LEDs to the case may vary due to the type of LEDs or the type of cases used.
After attachment, the relative positions and the projection angles of the LEDs may still be adjustable, allowing more flexibility as to the area, scope, and depth of illumination. Moreover, the attachment method for the LEDs may be designed in such a way that allows the LEDs to illuminate to a direction not generally perpendicular to the front side the handheld computing device. For example, each LEDs may be mounted on the case with a universal wheel that allows the LED to tilt to all directions. Thus, when it is desirable to use the LEDs with the back camera of the handheld computing device, such designs may allow the LEDs to illuminate in the direction of the back camera.
As indicated above, the attachment assembly may take other forms apart from a case 55. The key is to enable the attachment assembly to attach the light source 10 to the handheld computing device. In the simplest format, the light source 10 may be mounted directly on the handheld computing device, making the light source 10 integral to the handheld computing device. In that case, the attachment assembly may simply comprise the minimum material or structure, such as the magnet, glue, screw, rivet, or welding material that connects the light source 10 to the handheld computing device. In a more complex form, the attachment assembly may comprise simply of one or more attachment strips that have the LEDs mounted on the strips and these strips may be attached to the handheld computing device through any means possible. The strips may be connected to the handheld computing device with screws or hinges, allowing the strips to tilt away from the handheld computing device while maintaining the attachment, enabling the LEDs to illuminate a wider area. When necessary, the LEDs may even be removed from the handheld computing device and the attachment assembly may comprise an extension cord that allow the LEDs to be powered, controlled, and provide illumination to an extended area. Such a design may be helpful to maximize the illumination scope of the illumination device.
The illumination device 1 may further comprise a sensor that detects and measures ambient light conditions. The general structure and circuitry for such sensor is well known in the arts. An ambient light sensor (see
The power connector 40 represents a means to connect the LEDs to a power source, such as the power source 30 shown in
The dock 60 may be considered a part of the attachment assembly, together with the case. Like the power connector 40, the dock 60 is not an indispensable structure of the illumination device. However, the dock 60 may play some important roles if it is present. The dock 60 may serve as part of the “snap-in” structure that secures the handheld computing device 100 in the case 55. More importantly, the dock 60 may include connectors that may be plugged into the handheld computing device 100 and serve to integrate the illumination device 1 with the handheld computing device in terms of data sharing, synergistic control, and sharing of power sources. The technology to enable the dock 60 to serve as a connector to the handheld computing device 100 is well known in the arts.
The light covers 20 may be a lens used to diffuse the light from the LEDs, focus the lights from the LEDs, and/or add certain colors when the LED light is white. The light cover 20 may diffuse and soften the light from the LEDs and help to achieve optimal illumination without creating a blind effect.
The light cover 20 may be any kind of diffuser, such as but not limited to: polycarbonate LED diffuser, acrylic LED diffuser, clear LED diffuser, opal LED diffuser, satin LED diffuser, LED diffuser films, or any product or material having LED light diffusing capability. The light covers 20 may also be any kind of lens that is adjustable or unadjustable. The light covers 20 may be colored, changing white light emitted by the LEDs to color lights.
The light covers 20 may be attached to the LEDs or to the case. The manner of attachment may vary according to the materials used and the specific configuration of the different structures. The light covers 20 may be slidable or rolling covers that may be attached or detached easily. The light covers 20 also be glued, screwed, welded, or riveted to the LEDs or the attachment assembly.
The configuration of the light covers 20 may differ from what is shown in
As indicated above, the attachment assembly may take many forms. The case 55 here is one example that allows both light source 10 attachment and general protection to the handheld computing device. Certain methods to mount the light source 10 to the case may allow the light source 10, preferably LEDs, to be adjustable in position and used with the back camera 125. In such circumstances, the LEDs may assist the photo or video capturing process or other applications conducted with the back camera.
The attachment assembly may also comprise other structures that may be combined with the case 55. One possible addition is a hand-free structure such as but not limited to a frame stand and/or a hanger. The frame stand or hanger is preferably foldable and may attach to the back of the case 55, occupying little space with folded. When the frame stand or hanger is unfolded, it may support or hang the handheld computing device in an upright position, allowing the display to be viewed comfortably by a user without occupying a user's hand. More particularly, the side(s) and bottom edge of the case may be able to be made with an angled surface so that the case may serve as part of a stand. For example, the thicker bottom area in a case, adjacent to where the external battery is installed, may provide enough surface to support an IPhone® at an angle. In summary, the frame stand or hanger enables hand-free viewing of the handheld computing device, providing more flexibility as to what can be done with the device.
It should be noted that the second and third embodiments may not necessarily be described to the fullest extent because such descriptions are provided for the first embodiment. In particular, the description for any of the embodiments should be considered included other embodiments as long as there is not conflict between the descriptions.
In the third embodiment, some other features such as the attachment assembly, the power source 30, the dock 60, and the illumination device switch 70 are not displayed. However, it should be noted that these structures may still be present, but shielded from direct view. As indicated above, electroluminescent light using algae-based wire and panels, such as the light based on RiLi technology (produced by Revolution in Lighting, Inc.), may be used as the light source 10. The design of the circular light panel 200 is particularly suitable to use such lighting technology, which is in general energy efficient, long lasting, bright, and having a wide viewing angle. The circular light panel 200 is preferably thin and may attach to the handheld computing device 200 using an attachment assembly comprising any kind of connecting mechanism, such as industrial glue. It should also be noted that the design, size, and shape of the light panel 200 may vary according to functional and/or aesthetic needs. The power supply, the control system, and the possible varying display of lighting by the light source 10 are fully described above and below.
Referring now to
Each of the side surfaces 90 has a generally horizontal extension or light rail that extends past and from the front surface 110. The light rails generally comprise a light cover 20 and a plurality of light sources or LEDs. The plurality of light source 10 are preferably LEDs that emit white light. The white light can be produced via mixed-color lighting or phosphor conversion or any other suitable technology. In some instances, it may be desirable to have the LEDs be capable of producing different colors and/or differing shades of light and such LEDs may be incorporated as appropriate. The light source 10 may be any type of LEDs as previously described herein and are preferably surface mounted LEDs, or may alternatively be any other suitable type of light source, such as, without limitation incandescent, fluorescent, or high-intensity discharge (HID) bulbs.
The light covers 20, here, are coverings for the LEDs. The light covers 20 may cover, but not touch, each light source 10 individually or cover a number of light source 10 simultaneously. In other embodiments, the light covers 20 may cover, and touch, any one or more light sources 10. The light covers 20 are preferably translucent, and in some cases transparent, plastic coverings that serve to diffuse the light as it passes through these coverings. The light coverings 20 may be removable and may comprise different materials and colors to provide a particular degree of diffusion or a tint, shade, or other color distortion or any combination thereof to the light source 10. In other embodiments, the light covers 20 are permanently attached thereto.
Further, each of the light covers 20 are designed to permit light to be emitted outwards from the illumination device 1 along at least a 180° arc. This is due to the fact the light covers 20 are generally shaped to cover the area above the light source 10 and on each side of the light source 10 to the point at which the light source 10 terminate at the device. In some instances, the light covers 20 may further be disposed past the point of termination of the light source 10 and may allow for rear facing light source 10 using the same principles as the front facing light sources described herein.
The light covers 20 are preferably disposed along the length of the side surface(s) 90, but may fully encircle the case 55. The light covers 20 may also be intermittent with gaps or spaces in between a number of separate light covers. In a preferred configuration, one light rail is longer than the other light rail (see
Where the light covers 20 intersect with the top area and bottom area of the illumination device 1 a securement mechanism 75 is formed extending therefrom. This securement mechanism 75 may be located in at least one corner area and up to four or more corner areas. In a preferred embodiment, there are at least two securement mechanisms 75. The securement mechanism 75 manifests itself as a tab or extension that extends substantially perpendicularly from the top of the light cover 20. Preferably, the securement mechanisms 75 are disposed on opposite ends and opposite sides of the illumination device 1. This enables, for example, one securement mechanism to be disposed on the upper left side and the other to be disposed on the lower right side. This disparity provides the most secure arrangement of the two form securement mechanism. With three or more securement mechanisms, the arrangement is less vital as the extra points of contact override the necessity for a particular arrangement.
When a computing device is pushed downward into the recess the securement mechanisms 75 slide over a surface of the computing device thereby securing the position of and retaining the computing device therein. In order to remove the computing device, the case 55 is flexed downwards (away from the computing device) slightly, allowing the securement mechanisms 75 to withdraw or recede from covering the computing device and the computing device is subsequently removed.
Further features of the illumination device 1 include an aperture 135 to provide unrestricted or uninhibited access for a rear facing camera of the computing device. The position of the aperture 135 can be varied to accommodate any number of sizes, shapes, and positions. An ambient light sensor 145 may be disposed thereon to automatically adjust the intensity of the light sources 10 in accordance with the ambient light. A charging port 85 enables charging of the power source 30 (see
In addition, the illumination device 1 may provide for at least one depressible or touch sensitive button 80. In a preferred embodiment this button is located on the back side 115 of the illumination device 1. The touch sensitive button 80 controls an operative state of the light sources 10. This may include powering the light sources 10 on or off as well as serving to dim or intensify the light sources 10 as needed.
In order to dim or intensify the light sources 10 one would depress and continue to apply pressure to or leave their finger remaining over the button area. This action causes the light sources 10 to either dim or intensify until the button is ceased to have been engaged. Further engagement of the button 80 will result in further dimming or intensifying based on the current setting of the light sources 10.
In
There may be cutouts or voids 150 between areas of the light rails where such voids or spaces 150 have been strategically placed to enable interaction with the computing device once the computing device has been secured thereto. As shown, such voids 150 are shown along the top, bottom, and mid to upper left side of the case. These positions are the typical locations of buttons and other interactive features of computing devices, namely smart phones. However, the exact arrangement, size, and shape of such voids 150 can be altered as necessary.
As shown in
Referring now to
The light covers 20 are generally unitary, single channels that run along either side, or top or bottom of the front side 110. The light covers 20 may be disposed separately or may be connected forming a continuous cover traveling the length of the perimeter. In some embodiments the light covers 20 may be oriented to be positioned along the back side 115 as well. The light covers 20, as previously noted, are configured to diffuse light. Such diffusion may be accomplished by use of certain materials, textures, patterns, or the like or any combination thereof comprising the light covers 20. For example, denser materials are typically more efficient in diffusing light and such a material may be required with more luminous light sources.
Internally, a printed circuit board (PCB) 160 is shown with a rechargeable power source 30 coupled thereto. Power connectors 40, such as wiring, couples the light sources 10 to the power source. The depressible button 80 can function to alter an operative state of the light sources 10 including to turn light sources on/off as well as change the luminous output of the light sources 10.

Further, as shown in
In some instances, the general concept described herein in
As indicated above, it is in the purview of the current disclosure, as described in the Figures, that a series of computer applications or programs may accompany the illumination device disclosed herein. These applications may facilitate the use of the illumination device and ensure that it is safe, well-controlled, and optimized to assist the use of some other applications. However, it is of note that this is not a requirement and, in fact, it may be more practical to operate the present disclosure as a standalone embodiment. This gives full control over the illumination device 1 to the user. The user can couple the illumination device 1 to a computing device 100 as needed.
Once coupled to the computing device 100, the user can change the intensity or any other property of the light sources 10 by using controls, switches, and the like embedded with the illumination device 1 itself. Further, this standalone usage is enhanced by the rechargeable power source contained within the case 55. Thus, the power source may be recharged as necessary without requiring the computing device 100 to be recharged, nor would it drain a charge from the power source of the computing device.

As discussed above, the general concept described in
Referring to
The illumination device 1 takes the form of a case 55 and is shown without the handheld computing device 100 attached thereto. Generally, the embodiment has a front side 110, back side 115, top 105, bottom 95, and at least two side surfaces 90. The case 55 includes aperture 135 to provide unrestricted or uninhibited access for a rear facing camera of the computing device 100. Each rear light rail includes light sources 210 having light covers 220 that are separately disposed over respective light sources 210. Each front light rail includes light sources 10 having light covers 20 that are separately disposed over respective light sources 10.
Light sources 210 may be the same as light sources 10 except that light sources 210 are arranged on the back side 115 of the case 55. Light covers 220, similar to light covers 20, are configured to diffuse light. Light covers 220 may be the same as light covers 20 except that light covers 220 are disposed on back light sources 210. In some examples, light sources 10 and 210 may have the same light characteristic properties (e.g., producing the same colors). In some examples light sources 10 and 210 may have different light characteristic properties (e.g., producing different colors and/or differing shades of light). In some examples, light covers 20 and 220 may have the same properties (e.g., same material, same color, same tint). In some examples light covers 20 and 220 may have different properties (e.g., different material, different color, different tint). In some examples, rear facing light rails (light sources 210 and light covers 220) may be configured to provide more light and/or more diffusion than front light rails (light sources 10 and light covers 20), such as to provide improved captured images of groups of people with a back camera compared to “selfies” taken with a front camera.
In some examples, the forward facing light sources 10 and rear facing light sources 210 may be independently controlled, such as by touch sensitive button 80. Thus, rear facing light sources 210 may be turned on/off as necessary, and the case 55 may enable the same functionality to occur for the rear facing light sources 210 as described herein with respect to the forward facing light sources 10.
In
In some examples, the case 55 may include charging port 85, as described above. In some examples, the case 55 may include an external memory slot 222. The memory slot 222 may provide uninhibited access to a memory card interface of the handheld computing device 100. The memory slot 222 may be suitable for accepting any suitable external memory card known in the art, such as, but not limited to, a secure digital (SD) memory card.
Referring to
Internally, the PCB 260 is shown with a rechargeable power source 30 coupled thereto. Power connectors 40, such as wiring, couples the forward facing light sources 10 and the rear facing light sources 210 to the power source 30. The depressible button 80 can function to alter an operative state of the forward and rear facing light sources 10, 210, including, for example and without limitation, to turn light sources 10, 210 on/off as well as change the luminous output of the light sources 10, 210 (including independent control forward and rear facing light sources 10, 210).
Referring to
The case 55 shown in
As discussed above, light sources 10 (210) may be mounted to the case 55 by any means that allows secure attachment, and may also be designed in such a way that allows the light sources 10 (210) to illuminate to a direction not generally perpendicular to the front side 110 of the handheld computing device 100.
In particular,
As shown in
In contrast, in
In addition to allowing the light sources to generate light 224 in a direction away from perpendicular (relative to the front side 110), as shown in
As discussed above, the case 55 may include power source 30 that is separate from the internal power source of the handheld computing device 100. Referring next to
Referring to
In some examples, battery 30 may be permanently fixed in case 55. In some examples, battery 30 may be removably disposed in case 55. As discussed above, in some examples, battery 30 may be a disposable battery or a rechargeable battery or any other power source, such as solar.
Battery 30 may provide power to the light sources 10. Battery 30 may also serve as a backup power source to the handheld computing device 100. For example, with control circuitry and electrical connections (such as via dock 60 shown in
In some examples, the case 55 may include depressible or touch sensitive button 242 to control an operative state of the light sources 10 (e.g., powering light sources 10 on or off, changing a luminous output of light sources 10, viewing angle, color, lighting patterns, etc.). The functions of button 242 may be similar to touch sensitive button 80 and/or illumination device switch 70 as described above.
In some examples, the case 55 may include depressible or touch sensitive button 244 to control charging of the internal power source of the handheld computing device 100 by the power source 30. In some examples, button 244 may also control charging of an external device by power source, via discharging port 250. For example, depressing or touching button 244 may cycle through preset operation states, such as charging battery 30 via charging port 248, charging the internal power source of the handheld computing device 100 via charging port 248, charging the internal power source of the handheld computing device 100 via battery 30, discharging the battery 30 to power an external port via discharging port 250 and disabling charging/discharging of battery 30. In some examples, the functionality of button 244 may be combined with the functionality of button 242 into a single depressible or touch sensitive button.
In some examples, the case 55 may include charging indicator 246, such as a charging bar. Charging indicator 246 may include a battery meter that measures the battery life of power source 30 and may indicate the battery life remaining. Charging indicator 246 may also indicate to the user to change batteries or recharge battery 30 when necessary.
In some examples, the case 55 may include dedicated charging port 248, which may be operably coupled to power source 30 and the internal power source of the handheld computing device 100. The charging port 248 may be any type of suitable port including those known in the art such as a USB port, which provides for charging power source 30 and the internal power source of the handheld computing device 100. In some examples, the case 55 may also be configured to be wirelessly charged (also referred to as inductive charging). For example, the charging port 248 of case 55 may include an induction charger (having an induction coil) configured to be inductively coupled to a charging station (having its own induction coil), such as (without being limited to) a wireless charging pad. The induction coils in the induction charger and the charger stations may be inductively coupled to create an alternating electromagnetic field. The alternating electromagnetic field may be converted into an electric current by the induction charger of the case 55, to charge power source 30. In some examples, the induction charger may use resonant inductive coupling. In some examples, charging port 248 may include an induction charger in addition to a USB charging port. In some examples, case 55 may be configured to be kinetically charged. For example, case 55 may include a kinetic energy charger that may use motion of case 55 (e.g., by the user) to charge power source 30. In some examples, the kinetic charger of case 55 may also be configured to charge the internal power source of the handheld device 100.
In some examples, the case 55 may include dedicated discharging port 250 (separate from charging port 248), which may be operably coupled to power source 30. The discharging port 250 may be any type of suitable port including those known in the art such as a USB port, which provides for charging a downstream port (e.g., an external device) via power source 30.
In some examples, case 55 may include charging sensor 252 for controlling charging of the power source 30 and the internal power source of the handheld computing device 100. For example, charging sensor 252 may include suitable circuitry and electrical connections to measure a battery life remaining for each of power source 30 and the internal power source of the handheld computing device 100. Depending on the measured remaining battery life, charging sensor 252 may distribute energy received via charging port 248 (and/or a kinetic charger) among one or more of power source 30 or the internal power source, based on one or more predetermined conditions (such as prioritization of computing device charging over power source 30 charging). For example, charging sensor 252 may permit power source 30 to receive energy when there is greater than 80% internal battery life remaining. In contrast, charging sensor 252 may distribute energy to the internal battery when there is less than a certain percentage of internal battery life remaining, such as 20% internal battery life remaining. The one or more predetermined conditions for charging power source 30 and the internal battery may be preset by the illumination device 1 and/or may be selected by the user.

In some embodiments, the illumination device may implement shock absorbing features designed to protect the computing device from falls, shaking, and the like. In some embodiments, the illumination device may implement weather protective and/or dust protective features. In some examples, the illumination device may be designed to be water resistant. In some examples, the illumination device may be sealed, such as with one or more gaskets and/or plugs to cover any apertures (such as a charging port), to protect the illumination device and/or computing device from weather and/or dust. In other embodiments, a covering such as a glass or acrylic may overlay the computing device's display to prevent similar harm to the display of the computing device. In some embodiments, the illumination device may include a covering such as glass or acrylic to overlay the computing device's camera, to protect the camera of the computing device (e.g., from dust, dirt, fingerprints, etc.). In some examples, the covering for the camera may be attached to the illumination device in a permanent or removable manner. In yet other embodiments, the light sources may flash, strobe, or otherwise be used to signify that an emergency is occurring or to otherwise garner attention from another. In other embodiments, a “selfie stick” or other apparatus may be coupled to the illumination device to provide flexibility in use. In some examples, one or more attachment assembly may include one or more permanently or removably attachable protrusions for supporting the handheld computing device in a hands-free mode, for coupling the handheld computing device to another object and/or for easier grasping of the handled computing device. In some embodiments, the illumination device may have slots for cash, credit cards, debit cards, and the like. Even still, in other embodiments there may be an integrated battery and/or signal booster which can provide extended battery life and enhanced signal quality when necessary.
As indicated above, it is in the purview of the current disclosure that a series of computer applications or programs may accompany the illumination device disclosed herein. These applications may facilitate the use of the illumination device and ensure that it is safe, well-controlled, and optimized to assist the use of some other applications.
For example, when the illumination device is sufficiently connected and synergized with the computing device, a program may be used to specifically control the light source of the illumination device to adjust the luminous intensity, viewing angle, color, and lighting pattern of the light source. A user of a handheld computing device may turn on the illumination device simply to provide general illumination. A handheld computing device, in such situations, may be used as a flashlight in a dark place. When the illumination device is equipped with an ambient light sensor, as indicated above, it is possible to have a program that automatically adjusts the luminous intensity of the light source based on ambient light conditions.
Another example is a video call program that specifically integrates the usage of the illumination device. Before the user transmits his/her image, he/she may view the image on the display screen to obtain optimal results. The program may control both the camera and the illumination device, allowing easy adjustment without switch to another program that controls the camera. The program may facilitate this process by setting certain criteria that help the user to optimize the image. For instance, the program may display on the screen a dotted-line contour of a generic human face, while the user of the handheld computing device may adjust the distance of his/her face to the device and/or the zoom and focus of the front camera to make the image of his/her face to fit the dotted-line contour, achieving optimal results. A slight variation of this design is to display a generic eye contour that allows the user to make adjustment to match his/her image to the contour. Or the program may directly show suggestions or recommendations on the display screen to urge the user to turn the illumination device on, make it brighter or dim it, or to adjust the zoom and/or focus of the camera for optimal image. In essence, the illumination intensity may be adjusted according to the optimal focal length of the camera. Such a basic design should also be applicable to other programs. Similarly, a photo or video capturing program having the same features may be installed to assist the use of the illumination device. The photo or video capturing program may aid the user in adjusting the illumination device to obtain the best result as to picture quality. In some examples, the photo or video capturing program may integrate voice command recognition via the computing device with control of the lights of the illumination for capturing photos and videos. The program may allow the user to capture a photo or a video with the camera of the computing device through one or more voice commands together with illumination by the illumination device. Another example is a “makeup mirror” application that integrates the illumination device with the front camera. In some cases, a user of a handheld computing device would like to see his/her own image to be captured by the front camera and be displayed on the display screen simultaneously. The user then would be able to assess his/her appearance and make necessary adjustments. To achieve optimal results, the “makeup mirror” application would allow the user to control the luminous intensity, viewing angle, color, and lighting pattern of the light source in the illumination device, or such features may be adjusted automatically by the application when the ambient light sensor is included and used. Combined with the frame stand or hanger structure that may be a part of the attachment assembly, the user may set the handheld computing device in an upright position without actually holding the device, freeing up both of the user's hands for optimal maneuvering, while the whole process is being conducted under ideal illumination.
Also indicated as above, the illumination device may serve as indicator or signaling source for the status of the handheld computing device. For example, when there is an incoming call to a small phone, a handheld computing device, the light source of the illumination device may light up or change the luminous intensity, viewing angle, color, and/or lighting pattern of the lights. The lights may flash or subsections of the lights are turned on rotationally. A more complex set up may allow the user of the smart phone to establish and manage specific profiles—specific combination of luminous intensity, viewing angle, color, and/or lighting pattern—for the illumination device. The user may choose different profiles to match different callers. Such an application controls the illumination device in somewhat similar ways as ring tones are managed for smart phones, further enriching the user experience.
Furthermore, since the illumination device may be used as signals for the computing device to which the illumination device is connected, it is possible that the illumination device may be integrated with other program or application being used by the computing device. For example, it is possible to set up the illumination device that when a certain game is being played, the illumination device is turned on and the luminous intensity, viewing angle, color, and/or lighting pattern of the lights change with the progress of the game. A similar implementation is also possible for music. Certain light profiles may be integrated with the music program on the computing device, allowing the lights to flash rhythmically, for example, when the music is being played.
Although this disclosure has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the disclosure.
