Description

  The present invention relates to lighting devices, and more particularly, to facilitate video calling, video conferencing, other camera-related processing and other applications executed by a computing device that requires optimized lighting. The present invention relates to lighting devices that are attached to devices, particularly handheld computer devices such as smartphones.

  Computer devices, particularly handheld computer devices, have developed rapidly over the past 20 years. Here, as a computer device, a desktop computer, a laptop computer, and a handheld computer device are cited. , A computing tablet such as iPad (registered trademark), a personal digital assistant (PDA), and other devices that are relatively small and lightweight and have basic computing and internet connection capabilities. It is not limited. Computer devices are playing an increasingly important role in people's work, entertainment and communication.

  Most modern computing devices have a camera. In many cases, particularly for handheld computer devices, there are two cameras, one on the front of the device that is on the same side as a typical display screen and the other on the back. One fairly widespread use of computing devices is in some cases video calls or video conferencing, during which both video images and audio signals are transmitted and received. Most video images are captured by the front camera, which allows the device user to be visible at the same time as viewing the device display. A video call allows the caller to listen to another person's story and see another person at the same time. By combining the handheld computing device's portable functionality, video calling significantly facilitates communication and interaction between parties.

  However, one drawback of video calls made on computing devices is lighting that is unpredictable and often far from ideal, making video calls unattractive and impossible to continue. Even become. This problem is particularly acute for handheld computer devices. Due to the portability of handheld computer devices, video calls made by handheld computer devices may occur in some places that were previously unthinkable. Instead of a well-lit meeting room, the user of a handheld computer device may be in the car, in a dark room, or some place with weak or uncontrollable light, which The user's image cannot be shown appropriately. The present invention addresses this problem by providing a lighting device that can be attached to a computing device and can have light that the user can manage in the user's video call or video conference. Furthermore, the lighting apparatus introduced by the present invention may have a number of additional applications that provide significant convenience and greatly improve the user experience of the computing device.

  As mentioned above, “computer device” is a broad concept, referring to, but not limited to, desktop computers, laptop computers and handheld computer devices as computer devices. (Registered trademark) or Android (registered trademark) smartphone, iPad (registered trademark) computing tablet, personal digital assistant (PDA), and relatively small and lightweight, basic computing power and Internet connection Other devices with capabilities are not limited to such. Since the use of the present invention is shown in more detail in a handheld computing device, the discussion will focus on such an apparatus. However, the lighting device disclosed herein may be implemented with desktop and laptop computers and has significant advantages.

  With the realization of front and rear cameras, handheld computing devices can be used in ways that previously could not have been conceived. As mentioned above, one application is a video call or video conference where users can see and talk to each other simultaneously. In most cases, the user holds the handheld computer device in front of the handheld computer device that is defined as the side having the display screen and faces the user. Therefore, the front camera, which is a camera on the same side as the display screen, can acquire the user's image, particularly the user's face image. With the network construction function, the handheld computing device forwards the acquired images and recorded audio signals to other parties participating in the video call or video conference.

  However, such communication experience can be impaired by weak or inappropriate lighting. When very dark, it becomes very difficult for the front camera to obtain a user usable image and the video call becomes unattractive. In addition, many other camera-related processes and applications performed by handheld computing devices may have similar requirements for optimal lighting conditions. One simple example is the shooting or recording of the user himself, another person or other scene or object using a handheld computing device. When the ambient light is very weak, the photo or video results may be impaired. Another example is a “mirror” application on a handheld computing device that allows the user to see his own image on a display. Bad ambient light conditions also impair the use of such applications.

  Current devices address the above-mentioned problems by attaching a light source, preferably a plurality of light emitting diodes (LEDs) to the handheld computing device, whereby the light source illuminates the user, especially the user's face. The front camera or rear camera can acquire the best image of the user or any other subject and is associated with video calls, photo or video acquisition, “mirror application” or any other camera Make the experience easier.

  Furthermore, by using the basic design, there are various variations that provide different types of examples of lighting devices to meet different requirements for applications and users. Part of the application needs to be related to the camera. This is because the lighting device disclosed herein may have a signal transmission capability in addition to the function of performing lighting.

  As suggested, the light source is preferably an LED light. However, the light source may be a light bulb type fluorescent lamp (CFL) or other light such as an electroluminescent light. In particular, electroluminescent lights using algae-based wires and panels such as lights based on RILI technology may be incorporated as the light source of current devices. Furthermore, it is sometimes desirable to create a light that is adjustable with respect to luminous intensity, viewing angle and diffusion. The light can have a color by using a color light or by adding a color cover. In general, by implementing further adjustment functions, the lighting device can illuminate one or more people for various purposes. The lighting device can flash to show different patterns, thereby satisfying different requirements.

  There may be a power source that is separate from the power source of the handheld computing device. A power source may be connected to the light through a power connector to provide the energy required for lighting. The power source may be a standard AAA zinc carbon or alkaline battery or one or more batteries of other types or sizes that can meet energy requirements or physical containment requirements. The battery can be disposable or rechargeable, thereby allowing flexibility in terms of cost performance and convenience. A battery may be connected to both the lighting device and the handheld computer device, thereby supplying energy to both devices and serving as a backup or additional power source for the handheld computer device. In contrast, the light source can be simply connected to the handheld computer device and the light source can use the power of the handheld computer device, thereby reducing the size and weight of the lighting device and making it easier to carry.

  The lighting device includes a mounting component that attaches the light source to the handheld computing device. The mounting is preferably non-permanent so that lights can be added or removed as required by the user. The attachment component may take many forms. For example, the mounting component may be a flat case having a recess or docking location for a handheld computing device for mounting and a recess for receiving a power source and a power connector. The present invention includes all types of mounting components that allow a convenient connection between the light and the handheld computing device. In addition, the mounting component may be suitable for other purposes such as supporting the handheld computer device in an easy-to-view position so that a user of the handheld computer device can view the device in a hand free mode. Furthermore, more complex mounting components may have a structure that allows the lighting device to be further integrated into the handheld computing device from the perspective of joint control and data sharing.

  The lighting device may further comprise an external switch that allows the user to switch the light on and off. However, the buttons, switches and menus of the handheld computer device for controlling the light can be used, particularly when the lighting device is fully integrated into the handheld computer device.

  As described above, the lighting device may be used to facilitate video calls or video conferencing or to enhance functionality associated with other cameras of the handheld computing device. In such cases, the lighting device taught by the present invention can enhance such experience by providing additional well-controlled lighting.

  Furthermore, by using a further connection between the light and the handheld computer device, the light of the lighting device may serve as an indicator of the state of the handheld computer device or as a signal for applications used in the handheld computer device. . For example, the light may flash or turn on when there is an incoming call. The light may also change its lighting pattern, light intensity, or color when the user speaks on a handheld computer device or when playing a predetermined music or playing a game.

  The scope of the present invention is also a series of computer programs or applications that may be used to control the lighting device. For example, a basic version of such a program can adjust the brightness, viewing angle, lighting pattern and / or color of the lighting device. A further improved program allows the lighting device to cooperate with the state of the handheld computing device such as an incoming call. Yet another improved program may integrate other applications into the lighting device such that the light is partially controlled by the application.

  In general, lighting devices are small, portable, versatile, energy efficient, durable, and handheld computer devices, and more commonly used with lighting devices. Designed to fit well with computing devices.

  Preferred embodiments of the present invention will be described with reference to the drawings. The same components in the various drawings are given the same reference numerals.

  Embodiments of the present invention will be described in detail. Such an embodiment is provided by the description of the present invention, but the present invention is not limited thereto. Indeed, those skilled in the art will appreciate that various changes and modifications can be made upon reading the present specification and viewing the drawings of the present application.

  FIG. 1 is an isometric front view of a first embodiment of the present invention when a lighting device is connected to a handheld computing device. A lighting device 1 attached to a computer device is shown in FIG. 1, and the lighting device 1 includes a mounting part shown here as a case 55, a power source 30, a dock 60 for a handheld computer device, a lighting device switch 70, A light source including the LED. For clarity, all LEDs are not labeled in FIG. A handheld computer device 100 is also shown in FIG. 1, and the handheld computer device 100 includes a display screen 130 defining a front surface 100, an ON button 170, an OFF button 180, a MENU switch 190, and a front camera 120. An image 140 displayed on the display screen 130 is also shown in FIG.

  As mentioned above, handheld computing devices are widely defined. In FIG. 1, the handheld computer device 100 is shown as a smartphone having a display screen 130, an ON button 170, an OFF button 180, and a MENU button 190. However, it will be apparent that the present invention can be used to accommodate any computing device by making certain adjustments to the power supply 30, case 50 and dock 60. Further, the type and form of the handheld computing device 100 may vary significantly depending on the device brand and version. It is likely that the handheld computer device 100 does not have any of the buttons and switches shown in FIG. Nevertheless, it is clear that the invention provides a lighting device 1 that can accommodate any kind of computer device, in particular a handheld computer device.

  The image 140 shown in FIG. 1 here shows that it represents a possible display of the screen when the handheld computing device is in use. The image 140 may be an image of a party participating in a video call or video conference with a user of the handheld computer device. The image 140 may be an image of a user of the handheld computer device when a photo or video is acquired by the front camera. When the image 140 is an image of a user of a handheld computing device, the user may observe the image and adjust the light intensity, viewing angle, color, and lighting pattern of the light source 10 to achieve optimal results. The user may adjust the distance from the handheld computing device 100. The lighting of the user by the device is best when the proper distance from the camera to the user is achieved. The image 140 may be an image of an arbitrary person or target acquired by a camera other than the front camera. Further, the image 140 may serve to show any photograph or image displayed on the screen 130.

  An LED is a suitable type of light source 10, as shown in FIG. As described above, other types of light such as CFL or electroluminescent light may be used as the light source 10. The basic form of the LED may vary according to the specific requirements of the user and the specific use of the lighting device 1. For example, the luminous intensity, viewing angle, and color of the LED may vary from model to model. An LED that emits white light or color light can be used. A color cover or film may be used to allow the white LED to show color. Preferably, as shown in FIG. 1, a plurality of LEDs are used as the light source 10. However, only one light can be used. The LEDs may be individually or globally controlled with respect to switching the LEDs on or off or with respect to the LED intensity, viewing angle and color. Alternatively, the LEDs may be placed in subsections that can be controlled as separate subsections. For example, as shown in FIG. 1, the LEDs may be arranged in three subsections: four LEDs on the left, four LEDs on the right and two LEDs on the top. If desired by the user of the handheld computing device 100, the user can switch any subsection on and off or change the form of any subsection according to ambient light conditions, user attitude and / or the included application or process. You may choose as follows.

  The LED may have various technical specifications and dimensions. In general, the LEDs should be small and matched to the handheld computing device 100 and intended use. Standard T1 LEDs, T1-3 / 4 LEDs, various surface mount LEDs, small LEDs, medium LEDs, high power LEDs, LED panels, LED modules and other types of LEDs are all possible for specific use choices It is. Some specific types of LEDs may be used for special effects.

  For example, a single wavelength LED may be used for phototherapy. In general, LEDs may use power in the range of 0.1 mW to 50 W with currents in the range of 0.1 μA to 1 A and voltages in the range of 0.1 mV to 250V. The LED may emit white light or color light having a specific wavelength. In the preferred embodiment, the LED emits light with a warm color temperature or 2400K.

  The power supply 30 in FIG. 1 is not an essential component of the lighting device 1. In some situations, it is preferable to have a power supply 30 as shown in FIG. However, in other situations, having a power source presents different advantages. For example, when the lighting device 1 is provided with a connector for an external power supply of the handheld computer device 100, the lighting device 1 can share a power source with the handheld computer device 100, thereby complicating the structure of the lighting device 1. This makes it easier to control. However, if it is desirable to have a long battery life or it is desirable to have a changeable lighting device 1 that can be adapted to various handheld computing devices 100, having a power supply similar to the power supply 30 shown in FIG. May be advantageous. The reason is that the power connector may not be compatible with all different handheld computing devices.

  In FIG. 1, the power source 30 may be a battery. However, as long as energy is supplied to the light source 10, the power source 30 may be another type of power source. If a battery is used, the power source 30 may be a disposable or rechargeable battery that addresses various concerns such as cost and convenience. A variety of batteries can be used in terms of chemical composition. The types of batteries used as power source 30 include, but are not limited to, zinc-carbon batteries, alkaline batteries, aluminum batteries, dry batteries, lead acid batteries, lithium batteries, nickel batteries, potassium batteries, and sodium ion batteries.

  The power supply 30 is designed to supply power to the LEDs. When the voltage and current supplied from the power supply 30 are insufficient to power the LED, a regulator circuit such as a buck-boost converter is used to ensure that the output from the power supply is increased to adequately supply the LED. May be included. Such adjustment circuits are well known in the art. Further, the lighting device 1 may further include a battery meter that measures the battery life and informs the user that the battery should be replaced when necessary. Such battery meter technology is also well known in the art.

  In addition to supplying power to the LEDs, the power source 30 may serve as a backup power source for the handheld computing device 100. By using an appropriate connection between the handheld computing device 100 and the lighting device 1, the power supply 30 can be used to supply energy directly to the handheld computing device 100 for both control circuitry and electrical connections. This can increase overall battery life and provide greater flexibility. When the power supply 30 is rechargeable, the handheld computer device 100 may be recharged, thereby providing an affordable solution for supplying power to both the lighting device 1 and the handheld computer device 100.

  Note that FIG. 1 is illustrative for the location and placement of case 55 and power supply 30. The power supply 30 may be arranged at another position. For example, the power supply 30 may be shielded in a chamber attached to the back surface of the case 55.

  In FIG. 1, a lighting device switch 70 is also shown. Such an external switch of the power supply 30 is not an essential part of the lighting device 1. If the lighting device 1 is fully integrated into the handheld computer device 100, all aspects of the LEDs can be controlled via the buttons, menus and switches of the handheld computer device 100. Such a design may provide a full range of options for luminous intensity, viewing angle, color, and illumination pattern of individual, subsection or group-wide LEDs. However, in certain situations it is desirable to have an external switch. The reason is that the external switch can perform quick and easy control of the light.

  Note that switch 70 may have various designs to meet various requirements. The switch 70 can be mechanical, electrical or logical. In the simplest form of switch 70, switch 70 may switch all LEDs on and off without having any other adjustment capability. However, the switch 70 may be designed as a dimmer that determines the brightness or luminosity of a given range of LEDs. In one possible design, the switch 70 may control a mechanical means of adjustment, such as an articulating lens or lens covering the LED, which can change the illuminance. In order to allow the switch 70 to perform such a function, a well-known circuit such as a potentiometer may be included in the lighting device. In addition, the switch 70 may have a more complex design to control the brightness, viewing angle, color, and illumination pattern of individual, subsection or group-wide LEDs.

  The present invention discloses a mounting part for attaching the light source 10 to a computer device. In the embodiment shown in FIG. 1, the computer device is a handheld computer device 100, whereas the attachment is a case 55 having a recess that partially encloses the handheld computer device 100, and the display screen 130 is clearly defined. The front surface 110 is greatly exposed so that the front camera 120 is not blocked. Handheld computing device 100 snaps into the recess of case 55. The LED is attached to the edge of the case 55 to direct light from the LED in a direction generally perpendicular to the front surface 110 of the handheld computing device 100.

  Case 55 may be a one-piece construction or may have a multi-piece design for additional flexibility and convenience. In addition to attaching the light source 10 to the handheld computer device 100, the case 55 may provide physical and sanitary protection for the handheld computer device 100, thereby preventing damage from physical impact. Case 55 is made of rubber, leather, wood, marble, artificial stone (for example, Silstone (registered trademark)), graphite (for example, carbon fiber), metal sheet or metal foil, or polyethylene terephthalate (PET), polyethylene (PE ), High density polyethylene, polyvinyl chloride (PVDC), low density polyethylene (LDPE), polypropylene (PP), high impact polystyrene (HIPS) and plastic, including but not limited to, or some combination thereof It may be composed of materials including but not limited to. Case 55 may be constructed from a single material and different parts of case 55 may be constructed from different materials, thereby ensuring optimal protection and feel.

  Note that the “snap-in” design is not the only form of attachment for connecting the handheld computing device 100 to the case 55. For example, the case 55 may include two covers, one or both of which may be slidably connected to the handheld computing device 100. Handheld computing device 100 is secured to the case by other means such as pre-positioned screws, hook-and-loop fasteners, riveting or any other type of mechanism capable of secure attachment. You can also. Preferably, the case 55 is removably attached to the handheld computing device 100 so that it can be easily removed with a higher level of flexibility. However, permanent fixing of the case 55 to the handheld computer device 100 can also be allowed, which allows a high level of integration between the handheld computer device 100 and the lighting device 1.

  The LED may be attached to the case 55 by any means that allows safe attachment. The LEDs may be linked or inserted into the case 55 by welding, screwing, riveting, gluing, co-molded or any other method. Necessary structures such as pre-positioned magnets, hook-and-loop fasteners or snaps may be used to secure the LED to the case 55. In general, the LEDs may be permanently or removably connected to the case 55. Furthermore, the method of connecting the LEDs to the case may vary depending on the type of LED used or the type of case.

  After mounting, the relative position and projection angle of the LEDs may be adjustable, thereby allowing further flexibility with respect to illumination area, range and depth. Further, the LED mounting method may be designed such that the LED can be illuminated in a direction that is not substantially perpendicular to the front of the handheld computing device. For example, each LED may be attached to the case by a universal wheel that can tilt the LED in all directions. Thus, such a design allows the LED to illuminate in the direction of the rear camera when it is desired to use the LED with the rear camera of the handheld computing device.

  As described above, the attachment component may take a form different from that of the case 55. The key is to allow the light source to be attached to the handheld computing device 100 by means of attachment parts. In the simplest form, the light source 10 may be attached directly to the handheld computer device, which allows the light source to be integrated into the handheld computer device. In that case, the mounting component may simply have a minimal material or structure, such as a magnet, adhesive, screw, rivet or welding material that connects the light source 10 to the handheld computing device. In a more complex form, the mounting part may simply comprise one or more mounting strips, the mounting strips having LEDs mounted on the strips, these strips being any possible means May be attached to the handheld computing device via The strip may be connected to the handheld computer device by screws or hinges so that the strip can be tilted away from the handheld computer device while maintaining the attachment, and the LED illuminates a larger area Can do. If necessary, the LED may be removed from the handheld computing device, and the mounting component includes an extension cord that can power and control the LED and can be made to the area where the LED has extended illumination. Also good. Such a design can be useful to maximize the illumination range of the lighting device.

  The lighting device 1 may further include a sensor that detects and measures the state of ambient light. The general structure and circuitry of such sensors is well known in the art. The ambient light sensor (see FIG. 7) facilitates the process of adjusting the light intensity, viewing angle, color and lighting pattern of the handheld computer device, allowing automatic control when the appropriate computer program is installed. Become.

  FIG. 2 is an isometric side view of the first embodiment of the present invention when the lighting device is connected to a handheld computing device. In order to make various elements visible, a broken line indicating a structure shielded from view by the case 55 is used. A lighting device 1 having a case 55, a power source 30, a dock 60, a plurality of LEDs covered by the light cover 20, and a power connector for connecting the LEDs to the power source 30 is shown in FIG. A handheld computer device 100 encased in a case 55 is also shown in FIG. For clarity, not all LEDs or light covers are labeled in FIG.

  The power connector 40 represents means for connecting the LED to a power source such as the power source 30 shown in FIG. As described above, the power source 30 may be a battery or other type of power source that is compact and safe. The power connector 40 may be a conventionally known standard electrical wiring or any other type of circuit that can be used to connect the light source 10 to a power source.

  The dock 60 can be considered as a part of the mounting part together with the case. As with the power connector 40, the dock 60 is not an essential structure of the lighting device. However, the dock 60 can play an important role when present. The dock 60 can serve as part of a “snap-in” structure that secures the handheld computing device 100 within the case 55. More importantly, the dock 60 may include a connector that can be plugged into the handheld computing device 100 to integrate the lighting device 1 with the handheld computing device for data sharing, synergistic control, and power sharing. May play a role. Techniques that allow dock 60 to serve as a connector for handheld computing device 100 are well known in the art.

  The light cover 20 may be a lens used to diffuse light from the LED, focus light from the LED, and / or add a predetermined color when the LED light is white. The light cover 20 diffuses and weakens the light from the LEDs and helps to provide optimal illumination without blocking the light.

  The light cover 20 includes a polycarbonate LED diffuser, an acrylic LED diffuser, a clear LED diffuser, an opal LED diffuser, a satin LED diffuser, an LED diffuser film, or any product or material having LED light diffusion performance. It is good also as arbitrary kinds of diffusers which are not limited to this. The light cover 20 may be any type of lens that is adjustable or not adjustable. White light emitted from the LED by coloring the light cover 20 may be changed to color light.

  The light cover 20 may be attached to the LED or the case. The attachment method may vary depending on the materials used and the particular form of the various structures. The light cover 20 may be a slidable or rotating cover that can be easily attached or removed. The light cover 20 may be glued, screwed, welded or riveted to the LED or mounting part.

  The form of the light cover 20 may be different from that shown in FIG. For example, the light cover 20 may take the form of a “light strip” or “light pipe” that can cover two or more LED lights. In particular, one “light pipe” can cover the four LEDs on the left, another one “light pipe” can cover the four LEDs on the right, and another one “light pipe” The “pipe” can cover the top two LEDs, which allows for good diffusion and good illumination. Alternatively, a continuous “light strip” or “light bulb” may cover all LED lights.

  FIG. 3 is an isometric rear view of the first embodiment of the present invention when the lighting device is connected to a handheld computing device. A case 55 and handheld computer device 100 are shown in FIG. 3, which has a back surface 115 and a back camera 125 on the back surface 115.

  As described above, the mounting component can take a number of forms. Here, the case 55 is an example that can perform both attachment of the light source 10 and general protection of the handheld computer device. By a predetermined method of attaching the light source 10 to the case, the light source 10, preferably the LED, can be adjusted in position and used with the rear camera 125. In such situations, the LED supports a photo or video acquisition process or other application performed by the rear camera.

  The attachment component may include other structures that can be coupled to the case 55. One possible addition is a hand-free structure including but not limited to a frame stand and / or hanger. The frame stand or hanger is preferably foldable and can be attached to the back of the case 55 to occupy less space. If the frame stand or hanger is not folded, the frame stand or hanger supports or hangs the handheld computing device in an upright position, allowing the user to easily view the display without occupying the user's hand. More particularly, the (both) side and bottom edges of the case can be formed by an angled surface so that the case can serve as part of the stand. For example, the thick bottom surface of the case adjacent to the location where the external battery is attached can provide a sufficient surface to support the IPphone® at a predetermined angle. In summary, a frame stand or hanger can allow a handheld computing device to be viewed hands-free and provide sufficient flexibility in what it can do with the device.

  FIG. 4 is an isometric front view of a second embodiment of the present invention when the lighting device is connected to a handheld computing device. The lighting device 1 attached to the handheld computer device 100 is shown in FIG. 4, and the lighting device 1 includes a mounting part including a case 55 and a dock 60, and a plurality of LEDs. For clarity, not all LEDs are labeled in FIG. Also shown in FIG. 4 is a handheld computing device 100 having a display screen 130 defining a front side 110, an ON button 170, an OFF button 180, a MENU switch 190, and a front camera 120. An image 140 displayed on the display screen 130 is also shown in FIG.

  FIG. 5 is an isometric side view of the second embodiment of the present invention when the lighting device is connected to a handheld computing device. In order to make various elements visible, a broken line indicating a structure covered by the case 55 is used. FIG. 5 shows the lighting device 1 having a case 55, a dock 60, a plurality of LEDs covered by the light cover 20, and the power connector 40. A handheld computing device 100 in a case 55 is also shown in FIG. For clarity, not all of the LEDs or light covers are labeled in FIG.

  4 and 5 show a second embodiment of the present invention. In the present embodiment, the power supply and switch shown in FIGS. 1 and 2 no longer exist. The light source 10, here a plurality of LEDs, is connected to the internal power supply of the handheld computer device 100 by a power connector 40. Furthermore, by further integration of the lighting device 1 and the handheld computer device 100, the light intensity, viewing angle, color and lighting pattern of the light source 10 may be adjusted by the handheld computer device switches, buttons and menus, thereby A control switch is no longer needed. Such a design simplifies the basic structure of the lighting device 1 and nevertheless requires a high level of connection and cooperation between the lighting device 1 and the handheld computer device.

  It should be noted that the second and third embodiments need not be fully described. The reason is that such an explanation was made in the first embodiment. In particular, the description of any of the embodiments should be considered to be included in the other embodiments unless there is a contradiction between the descriptions.

  FIG. 6 is an isometric front view of a third embodiment of the present invention when the lighting device is connected to a handheld computing device. A lighting device 1 attached to the handheld computer device 100 is shown in FIG. 6, and the lighting device 1 includes a light source 10 including a circular light panel 200 that surrounds a display screen 130. A handheld computing device 100 having a display screen 130 defining a front face 110, a MENU switch 190 and a front camera 120 is also shown in FIG. An image 140 displayed on the display screen 130 is also shown in FIG.

  In the third embodiment, some other forms such as mounting parts, power supply 30, dock 60 and lighting device switch 70 are not shown. However, note that these structures exist but are not directly visible. As described above, an electroluminescent light using an algae-based wire and panel based on RiLi technology (manufactured by Revolution of Lighting, Inc.) using a light source 10 It may be used as The design of the circular light panel 200 is particularly suitable for using such lighting techniques, and is generally energy efficient, has a long lifetime, is bright and has a wide viewing angle. The circular light panel 200 is preferably thin and may be attached to the handheld computing device 200 using a mounting component comprising any type of connection mechanism, such as an industrial adhesive. The design, dimensions and shape of the light panel 200 may be varied according to function and / or aesthetic requirements. The possible display changes of illumination by the power supply, control system, and light source 10 are fully described above and below.

  With reference to FIGS. 7 and 8, there is another embodiment of the present invention shown from the front and back, respectively. The lighting device 1 takes the form of a case 55 and is shown without a computer device 100 (see FIG. 15) attached. In general, the embodiment has a front surface 110, a back surface 115, a top surface 105, a bottom surface 95 and at least two side surfaces 90. Each of these surfaces generally serves to define a recess 65 as shown in FIG.

  Each of the side surfaces 90 generally has a horizontal extension or light rail that extends from the front surface 110 beyond the front surface 110. The light rail generally includes a light cover 20 and a plurality of light sources or LEDs. The plurality of light sources 10 are preferably LEDs that emit white light. White light can be generated by mixing color light, phosphor conversion or other suitable techniques. In some instances, it is desirable to have LEDs that can generate different colors and / or have different light shades, and such LEDs are suitably incorporated. The light source 10 may be any type of LED as described above, and is preferably a surface mount LED, including but not limited to incandescent bulbs, fluorescent lamps or high intensity discharge (HID) lamps. An appropriate type of light source may be used.

  Here, the light cover 20 is an LED cover. The light cover 20 covers each light source 10 individually without contact, or covers a plurality of light sources 10 simultaneously. In other embodiments, the light cover 20 may cover and contact any one or more light sources 10. The light cover 20 is preferably translucent, and in some cases a transparent plastic cover, which serves to scatter light as it passes through the plastic cover. The light cover 20 is removable and may comprise different materials and colors to provide the light source 10 with a particular angle of scatter, light color, shade or other color distortion, or any combination thereof. In other embodiments, the light cover 20 is permanently attached.

  Furthermore, each of the light covers 20 is designed to emit light outward from the lighting device 1 along an arc of at least 180 °. This is because the light cover 20 is generally formed so that the light source 10 covers an area on the light source 10 that terminates in the device and on each side surface of the light source 10. In some examples, the light cover 20 may be positioned past the end point of the light source 10 and allows a back surface facing the light source 10 using the same principles as the front surface facing the light source described herein. To do.

  The light cover 20 is preferably disposed along the length of the (both) side surfaces 90, but may sufficiently surround the case 55. The light cover 20 may be intermittent by gaps or spaces between a plurality of individual light covers. In a preferred form, one light rail is longer than the other light rail (see FIG. 10). This serves to provide access to the form of a computing device, such as a smartphone, typically placed on the left side of the device.

  A fixing mechanism 75 extending from the light cover 20 is formed where the light cover 20 intersects the upper area and the lower area of the lighting device 1. At least one fixing mechanism 75 may be arranged in up to four corner areas. In the preferred embodiment, there are at least two locking mechanisms 75. The fixing mechanism 75 appears as a claw or extension that extends substantially vertically from the upper side of the light cover 20. Preferably, the fixing mechanism 75 is disposed on the opposite end and the opposite side of the lighting device 1. Thereby, for example, one fixing mechanism can be arranged on the upper right side and the other fixing mechanism can be arranged on the lower left side. This difference provides the most stable arrangement of the two forms of locking mechanism. By using more than two locking mechanisms, the placement is not critical since the additional contact points will dominate the need for a particular placement.

  When the computer device is pushed into the recess, the locking mechanism 75 slides on the surface of the computer device, thereby fixing and holding the position of the computer device. To remove the computer device, the case 55 is bent slightly downward (away from the computer device) so that the securing mechanism 75 pulls the computer device away or away from the cover, after which the computer device is removed. It is.

  Another form of the lighting device 1 has a hole 135 that provides unrestricted or unrestricted access to the rear camera of the computing device. The position of the hole 135 can be varied to fit some of the dimensions, shape and position. The ambient light sensor 145 may be arranged to automatically adjust the intensity of the light source 10 according to the ambient light. Charging port 85 may allow charging of power source 30 (see FIG. 1), which is a rechargeable power source, and charging port 85 may be located within the lighting device itself.

  Further, the lighting device 1 may include at least one push type or touch sensor type button 80. In a preferred embodiment, this button is located on the back surface 115 of the lighting device 1. The touch sensor type button 80 controls the lighting state of the light source 10. This includes the action of switching the light source 10 on or off and weakening or strengthening the light of the light source 10 as needed.

  Continue to apply pressure to the button area or leave your finger on to reduce or increase the light of the light source 10. This action causes the light source 10 to weaken or increase the light until the button is no longer involved. As a result of the further involvement of the button 80, the light is further attenuated or further enhanced based on the current setting of the light source 10.

  9 to 12, the embodiment shown in FIGS. 7 and 8 is shown from the right side, the left side, the top surface, and the bottom surface, respectively. Here, the whole, shape, and structure of the lighting device 1 are further clarified from the correlation among the front surface 110, the back surface 115, the top surface 105, the bottom surface 95, and the side surface 90. The light source 10 is shown from one arrangement structure.

  There may be a notch or void 150 between the areas of the light rail, such a notch or space 150 to allow interaction with the computer device once the computer device is secured. Arranged strategically. As shown, such a notch 150 is shown from the middle to the top of the top, bottom and left side of the case. These locations are typical locations for buttons and other forms of interaction on computing devices or smartphones. However, the additional arrangement, size and shape of such notches 150 can be varied as needed.

  As shown in FIG. 12, the charging port 85 is typically disposed on a button of the lighting device 1. The charging port 85 may be any type of suitable port, including those known in the art such as a universal serial port (USB) with both a charging downstream port and a dedicated charging port and other suitable charging technologies. The port is operably coupled to a power source included for charging as needed.

  Referring to FIG. 13, the light cover 20 is partially removed to expose the light source 10 from below. The arrangement and number of such light sources 10 is one of a myriad of such arrangements and is intended to be a mere representation of one such arrangement. See how one of the light rails (left light rail of this embodiment) contains more light sources 10 and is longer than the other light rail (right light rail of this embodiment) You can also. In other embodiments, longer light rails with more light sources 10 and shorter light rails with fewer light sources may be reversed. As can be appreciated, the number of light sources on each rail and the length of each rail may be varied as desired to include any number and / or arrangement of light sources 10 on each rail, and the length of each rail. May be varied to be longer or shorter as desired.

  FIG. 14 illustrates an iteration of the present disclosure as shown in the cross-sectional view of FIG. As shown, there is generally a front surface 110, a back surface 115, and a side surface 90 that serve to form a recess 65 for receiving a computing device. It is the light cover 20 that emerges or rises from the side surface 110. The light cover 20 is generally inverted "U" shape as shown, but depending on the light source 10 used and the diffusion choice of the light source 10, it can be further rounded to a "C" shape or other It may be a shape.

  The light cover 20 is typically a single channel that extends along any side, top or bottom surface of the front surface 10. The light covers 20 may be placed individually or connected together to form a continuous cover that extends along the length of the boundary. In some embodiments, the light cover 20 may be positioned for positioning along the back surface 115. The light cover 20 is configured to scatter light as described above. Such scattering can occur by using a predetermined material, structure, pattern, etc. of the light cover 20 or any combination thereof. For example, high density materials are typically effective for light scattering, and such materials may be required with more light sources.

  Inside, a printed circuit board (PCB) 160 is shown with a rechargeable power supply 30 coupled thereto. A power connector 40, such as wiring, couples the light source 10 to a power source. The push button 80 can function to change the lighting state of the light source 10 including switching the light source on / off and changing the light output of the light source 10.

  In FIG. 15, a lighting device 1 having a computing device 100 detachably coupled is shown in a perspective view. The computer device 100 has a display screen 130, a front camera 120, a computer device controller 155, and other forms that are not explicitly named. By partially enclosing the computing device with scattered light from the light source 10 and the light cover 20, the present invention enables uniform and consistent illumination of the object, which will be further described herein. Desirable acquisition of still images and time-varying images.

  Further, as shown in FIG. 15, the light sources 10 are arranged equidistant from each other. The spacing or gap between these light sources 10 may vary, but is preferably about 0.1 inches to about 0.2 inches, and more preferably about 0.25 inches. A gap or interval is defined as an area where the placement of one light source ends and the placement of the other light source begins. The light source 10 may be in a strip that operably couples each light to each other, otherwise it may be directly on a printed circuit board as described above. Other functional implementations may be used and are covered within the scope of the present invention.

  In some cases, the general concepts described in FIGS. 7-14 can be used with a rear camera. In such an embodiment, the positioning of the light rail including the light source and the light cover is the back instead of the front. The recess, fixing mechanism, hole, etc. remain in the same position as the front realization. In some embodiments, there are front and back light rails that include a light source and a light cover as described herein. In such an embodiment, the light sources (front and back) may be controlled independently, so that the back light source can be switched on / off as needed, with the same functionality. Can be generated by a front light source.

  As described above, it is within the scope of the present invention, as described in the drawings, for a series of computer applications or programs to occur with the lighting device disclosed herein. These applications can simplify the use of lighting devices and ensure that supporting the use of some other applications is safe, well controlled and optimized. However, it should be noted that this is not essential and in practice it is more practical to implement the invention as an independent embodiment. This gives the user sufficient control of the lighting device 1. The user can couple the lighting device 1 to the computer device as needed.

  Once coupled to the computing device 100, the user can change the intensity of the light source or any other characteristic by using a controller, switch, etc. that is incorporated into the lighting device 1 itself. Furthermore, this independent use is enhanced by a rechargeable power source contained within case 55. Therefore, the power source can be recharged as needed without the need to recharge the computer device 100 or the need to charge from the power source of the computer device.

  Next, another embodiment of the lighting device 1 will be described with reference to FIGS. 16A to 24F. Note that these embodiments need not be fully described. The reason is that such an explanation has been made in the embodiment described above. In particular, the description of any of the embodiments should be considered to be included in the other embodiments unless there is a contradiction between the descriptions.

  As described above, the general concept described in FIGS. 7 to 14 can be used by using a rear camera. In some embodiments, there are a front light rail and a back light rail including a light source and a light cover. FIGS. 16A-16D show an example of a case 55 having both a front light rail and a rear light rail that include light sources 10, 210 and light covers 20, 220, respectively, using both a front camera and a rear camera. Can be used. The type, arrangement, form, position and number of light sources 10, 210 are one of a myriad of such arrangements and are intended to be merely a representation of one such arrangement. As can be appreciated, the number of light sources 10, 210 on each rail and the length of each rail may be as desired to include any type, form, location, number and / or arrangement of light sources 10, 210 on each rail. The length of each rail may vary and may be longer or shorter as desired.

  16A-16F, an embodiment of a case 55 having a front light rail and a back light rail is shown. In particular, FIGS. 16A-16C show a rear view, front view, and perspective view of a case 55 having a front light rail (including light source 10 and light cover 20) and a back light rail (including light source 210 and light cover 220). . 16D and 16E show cross-sectional views of case 55 along line 16D-16D of FIG. 16A according to various arrangements of front and back light rails. 16F is a cross-sectional view of case 55 taken along line 16F-16F of FIG. 16B and shows the electrical connections of the components of case 55. FIG.

  The lighting device 1 takes the form of a case 55 and is shown without an attached handheld computing device 100. In general, the embodiment has a front surface 110, a back surface 115, a top surface 105, a bottom surface 95 and at least two side surfaces 90. Case 55 has a hole 135 that provides unrestricted or unrestricted access to the rear camera of computing device 100. Each back light rail includes a light source 210 having a light cover 220, and the light cover 220 is individually disposed on each light source 210. Each front light rail includes a light source 10 having a light cover 20, and the light cover 20 is individually disposed on each light source 10.

  The light source 210 may be the same as the light source 10 except that the light source 210 is disposed on the back surface 115 of the case 55. Similar to the light cover 20, the light cover 220 is configured to scatter light. The light cover 220 may be the same as the light cover 20 except that the light cover 220 is disposed on the back light source 210. In some examples, the light sources 10 and 210 may have the same light characteristics (eg, generation of the same color). In some examples, the light sources 10 and 210 may have different light characteristics (eg, generation of different colors and / or different light shades). In some examples, the light covers 20 and 220 may have the same characteristics (eg, the same material, the same color, the same hue). In some examples, the light covers 20 and 220 may have different properties (eg, different materials, different colors, different shades). In some examples, an image of a group of people taken with a rear camera is better than a “selfie photo” taken with a rear light rail (light source 210 and light cover 220), for example, with a front camera. In addition, it may be configured to provide more light and / or scattering than the front rail (light source 10 and light cover 20).

  In some examples, the front light source 10 and the back light source 210 may be independently controlled by, for example, a touch-sensitive button 80. Therefore, the back light source 210 may be switched on / off as needed, and the case 55 can cause the same function as described here for the front light source 10 to be produced for the back light source 210.

  16A-16E, the light sources 10, 210 (and each light cover 20, 220) are shown as being disposed along the length of the (both) side surfaces 90. In some examples, the light sources 10, 210 (and each light cover 20, 220) sufficiently surround the case 55. In some examples, the light sources 10, 210 (and each light cover 20, 220) may be disposed along the length of the top 105 (as shown in FIG. 1) or the length of the bottom 95 of the case 55. You may arrange along.

  In some examples, the case 55 may include a charging port 85 as described above. In some examples, case 55 may include an external memory slot 222. Memory slot 222 may provide unrestricted access to the memory card interface of handheld computing device 100. The memory slot 222 may be suitable for receiving any suitable external memory card known in the art, including but not limited to a secure digital (SD) memory card.

  Referring to FIGS. 16D and 16E, two exemplary arrangements of front light source 10 and rear light source 210 are shown. 16D and 16E also show the arrangement of the front light cover 210 relative to the light source 210. FIG. For convenience, the light cover 20 is not shown in FIGS. 16D and 16E. In FIG. 16D, the front light source 10 and the back light source 210 are placed on the PCB 260 such that the light sources 10, 210 are aligned with each other (beyond the PCB 260). In FIG. 16E, the front light source 10 and the back light source 210 are placed on the PCB 260 such that the light sources 10, 210 are in a shifted arrangement (ie, not aligned). It should be understood that FIGS. 16D and 16E represent examples of front and rear light source arrangements and that other arrangements are possible.

  FIG. 16F shows an example of the electrical connection arrangement of a part of the components of the case 55 (and the case shown in FIG. 17B) shown in FIG. As shown, there are a front surface 110, a back surface 115, and a side surface 90 that serve to form a recess for receiving the computing device 100. It is the light cover 20 that emerges or rises from the front face 110. From the back surface 115 is a back light cover 220.

  Internally, PCB 260 is shown with rechargeable power supply 30 coupled thereto. A power connector 40 such as wiring couples the front light source 10 and the back light source 210 to the power source 30. The push button 80 includes, but is not limited to, on / off switching of the light sources 10, 210 (including independent control of the front light source 10 and the back light source 210) and changing the light output of the light sources 10, 210. It can function to change the lighting state of 210.

  17A-17D, another embodiment of a case 55 having a front light rail and a back light rail is shown. In particular, FIGS. 17A and 17B show rear and front views of case 55 having a front light rail (including light source 10 and light cover 20) and a back light rail (including light source 210 and light cover 220). 17C and 17D show cross-sectional views of case 55 along line 17C-17C of FIG. 17A according to various arrangements of front and back light rails. For convenience, the light cover 20 is not shown in FIGS. 17C and 17D.

  The case 55 shown in FIGS. 17A to 17D is the same as the case 55 shown in FIGS. 16A to 16E except that the shape of the light cover 220 is different from that of the light cover 220 shown in FIGS. 17A to 17D, the back light cover 220 may cover two or more light sources. For example, the light cover 220 may take the form of a continuous “light strip” or “light pipe” (as described above for the light cover 20) that can simultaneously cover all the light sources 220 of each back light rail. .

  As described above, the light source 10 (210) may be attached to the case 55 by any means that allows safe attachment, and illuminates a direction in which the light source 20 (210) is not substantially perpendicular to the front surface 110 of the handheld computing device 100. It may be designed to be possible. 18A to 19D show various attachment positions of the light source 10 in the case 55. FIG. 18A to 19B show examples of the side light source 10. 19C and 19D show an example of the front light source 10. Although FIGS. 18A-19D show examples of front light rails, it should be understood that the exemplary design can also be applied to a back light rail and a combination of front and back light rails.

  In particular, FIG. 18A is a cross-sectional view of case 55 from front surface 110 having a portion (including light source 20) removed to expose the underlying light source. 18B is a cross-sectional view taken along line 18B-18B of case 55 shown in FIG. 18A. 18C is a cross-sectional view of the portion 18C shown in FIG. 18B. 19A is a cross-sectional view taken along line 18B-18B of case 55 shown in FIG. 18A having a portion (including light cover 20).

FIG. 19D is a cross-sectional view of the portion 19D shown in FIG. 19C.

  As shown in FIGS. 18A to 18C, the case 55 may include the light source 10 attached to the PCB 161. Each PCB 161 is attached to the case 55 parallel to the side surface 90 (via attachment to the back surface 115) such that the PCB 161 extends perpendicular to the front surface 110. The light source 10 may be attached to each PCB 161 such that the light source 10 faces the side surface 90 (in the emission direction), thereby forming the light source 10 facing the side surface. As shown in FIGS. 19A and 19B, the light 224 from the light source 10 may be emitted through the (one or more) light covers 20 in a direction that is not substantially perpendicular to the front surface 110 of the case 55.

  On the other hand, the light source 10 may be attached to the PCB 163 in FIGS. 19C and 19D. Each PCB 163 may be attached to the case 55 parallel to the side surface 90 (via attachment to the side surface 90) such that the PCB 163 extends parallel to the front surface 110. The light source 10 may be attached to each PCB 161 such that the light source 10 faces the side surface 110 (in the emission direction), thereby forming the light source 10 facing the side surface. As shown in FIGS. 19C and 19D, the light 226 from the light source 10 may be emitted through the (one or more) light covers 20 in a direction substantially perpendicular to the front surface 110 of the case 55.

  In addition to allowing light 224 to be generated in a direction away from normal (relative to front surface 110) as shown in FIG. 19B, the light source that faces the side (shown in FIGS. 19A and 19B) Thus, the case 55 can be formed in a more compact width shape (between the side surfaces 90) than the case 55 shown in FIG. 19C. The reason is that the PCB 161 is arranged perpendicular to the front surface 110.

  As described above, the case 55 may include a power supply 30 that is separate from the internal power supply of the handheld computing device 100. Next, an example of the case 55 having the power supply 30 will be described with reference to FIGS. 20A and 20B.

  The battery 30 may supply power to the light source 10. The battery 30 may serve as a backup power source for the handheld computing device 100. For example, the battery 30 may be used to provide energy directly to the handheld computing device 100 by using control circuitry and electrical connections (such as via the dock 60 shown in FIG. 1), thereby providing Increases overall battery life. When the battery 30 is rechargeable, the handheld computer device 100 can also be recharged, which allows a simple solution for powering both the lighting device 1 and the handheld computer device 100.

  In some examples, the case 55 is a push type that controls the lighting state of the light source 10 (e.g., switching the power supply 10 on or off, changing the light output of the light source 10, viewing angle, color, illumination pattern) or Touch-sensitive buttons 242 may be included. The function of the button 242 may be the same as that of the touch-sensitive button 80 and / or the lighting device switch 70 described above.

  In some examples, the case 55 may include a push or touch sensitive button 244 that controls charging of the internal power source of the handheld computing device 100 by the power source 30. In some examples, button 244 may control charging of an external device by a power source through discharge port 250. For example, the push-type or touch-sensitive button 244 can be used to charge the battery 30 via the charging port 248, to charge the internal power supply of the handheld computer device 100 via the charging port 248, and to inside the handheld computer device 100 via the battery 30. A preset operation state such as charging of the power source, discharging of the battery 30 for supplying power to the external port via the discharging port 250, and stopping / discharging of the battery 30 may be repeated. In some examples, the function of the button 244 may be incorporated into the function of the button 242 to form a single push or touch sensitive button.

  In some examples, case 55 may include a charge indicator 246, such as a charge bar. Charging indicator 246 may include a battery meter that measures the battery life of power supply 30 and may represent the remaining battery life. The charge indicator 246 may display to the user to replace the battery or recharge the battery 30 when necessary.

  In some examples, the case 55 may include a dedicated charging port 248 that can be operatively coupled to the power source 30 and the internal power source of the handheld computing device 100. Charging port 248 may be any type of suitable port, including those known in the art, such as a USB port with power supply 30 and an internal power supply for handheld computing device 100. In some examples, the case 55 may be configured for wireless charging (also referred to as inductive charging). For example, the charging port 248 of the case 55 is configured to be inductively coupled (having an induction coil) to a charging station (having its own induction coil) including, but not limited to, a wireless charging pad. An inductive charger may be included. The induction charger and the charging station induction coil may be inductively coupled to produce an alternating electromagnetic field. The power supply 30 may be charged by converting the AC electromagnetic field into a current by the induction charger of the case 55. In some examples, the inductive charger may use resonant inductive coupling. In some examples, the charging port 248 may include an inductive charger in addition to the USB charging port.

  In some examples, case 55 may include a dedicated discharge port 250 that may be operatively coupled to power supply 30 (separated from charge port 248). The discharge port 250 may be any type of suitable port, including conventionally known ones such as a USB port that charges a downstream port (eg, an external device) via the power supply 30.

  In some examples, the case 55 may include a charge sensor 252 that controls charging of the power supply 30 and the internal power supply of the handheld computing device 100. For example, the charge sensor 252 may include any circuitry and electrical connections for measuring the remaining battery life of each of the power source 30 and the internal power source of the handheld computing device 100. Depending on the measured remaining battery life, the charging sensor 252 may determine whether the power supply 30 is based on one or more predetermined conditions (such as the priority of charging of the computing device above the charging of the power supply 30). Alternatively, the energy received via the charging port 248 between one or more of the internal power sources may be distributed. For example, the charge sensor 252 allows the power supply 30 to receive energy when the remaining life of the internal battery is above 80%. In contrast, the charge sensor 252 may distribute energy to the internal battery when the remaining life of the internal battery is less than a predetermined percentage, such as a remaining life of the internal battery of 20%. One or more predetermined conditions for charging the power supply 30 and the internal power supply may be preset by the lighting device 1 and / or selected by the user.

  Referring to FIG. 20B, the case 55 may include a power supply 30 (also referred to as a battery 30) that is disposed in a chamber (not shown) of the case 55 and fixed by a cover 242 attached to the back surface 115 of the case 55. .

The charge / discharge port 254 may charge both the power supply 30 and the internal power supply of the handheld computing device 100 and may charge the downstream port via the power supply 30. The charge / discharge port 254 may be any type of suitable port, including those known in the art such as a universal serial bus (USB) port and / or an inductive charger (for wireless charging). In some examples, case 55 may include an inductive charger in addition to a USB type charge / discharge port.

  In some embodiments, the lighting device may implement a shock absorbing configuration that is designed to protect the computing device from falling, vibrating, and the like. In other embodiments, a cover such as glass or acrylic is overlaid on the display of the computer device to prevent similar adverse effects on the display of the computer device. In yet another embodiment, the light source may use a flash, strobe, etc. to signal that an emergency has occurred or to attract the attention of others. In other embodiments, a “selfie stick” may be coupled to the lighting device for flexibility in use. In some embodiments, the lighting device may have slots for cash, credit cards, debit cards, and the like. Furthermore, in other embodiments, there may be an integrated battery and / or signal booster that can extend battery life and improve signal quality as needed.

  As mentioned above, it is within the scope of the present invention for a series of computer applications or programs to occur with the lighting device disclosed herein. These applications can simplify the use of lighting devices and ensure that supporting the use of some other applications is safe, well controlled and optimized.

  For example, when the lighting device is fully connected and cooperating with the computer device, the program is used to specifically control the light source of the lighting device to adjust the light intensity, viewing angle, color and lighting pattern of the light source. May be. The user of the handheld computing device may simply turn on the lighting device for general lighting. The handheld computing device may be used as a flashlight in the dark in such situations. When the ambient light sensor is attached to the lighting device, as described above, a program for automatically adjusting the light intensity of the light source based on the state of the ambient light can be provided.

  Another example is a video call program that specifically integrates the use of lighting devices. Before the user sends his image, the user may view the image on the display screen for optimal results. The program may control both the camera and the illuminating device, so that adjustment can be easily performed without switching to another program for controlling the camera. The program facilitates this process by setting predetermined criteria that help the user to optimize the image. For example, the program may display a dashed outline of a typical human face on the screen, during which time the user of the handheld computing device will move the user's distance to the device to fit the image of the user's face to the dashed outline. And / or the zoom may be adjusted and the front camera may be focused, thereby achieving optimal results. A slight change in this design is to display a general eye contour, which allows the user to adjust the user's image to match the contour. The program also provides suggestions or recommendations directly on the display screen to prompt the user to turn on the lighting device, make the lighting device brighter or darker, or adjust the camera zoom and / or focus for optimal images. May be shown. In essence, the illuminance may be adjusted according to the optimal focal length of the camera. Such a basic design should be compatible with other programs. Similarly, a photo or video acquisition program having the same function may be installed to assist the use of the lighting device. The photo or video acquisition program assists the user in adjusting the lighting device to obtain optimal results for image quality.

  Another example is a “makeup mirror” application that integrates the lighting device into the front camera. In some cases, the user of the handheld computing device desires to see the user's own image acquired by the front camera and displayed on the display screen at the same time. In this case, the user can evaluate the appearance of the user and make necessary adjustments. In order to achieve optimal results, the “makeup mirror” application allows the user to control the light intensity, viewing angle, color and lighting pattern of the light source of the lighting device, or such a form can be achieved by the ambient light sensor. It may be automatically adjusted by the application when it is included and used. By combining a frame stand or hanger structure that may be part of the mounting component, the user can set the handheld computer device upright without actually holding the device for optimal operation. The user's hands are free and at the same time the entire process is performed under ideal lighting.

  As mentioned above, the lighting device may serve as an indicator or signal source for the state of the handheld computing device. For example, when there is an incoming call to a handheld computer device of a small telephone, the light source of the illuminator may be turned on or the light intensity, viewing angle, color and / or illumination pattern may be changed. The light may generate a flash or it may turn on sub-sections of the light in turn. More complex settings allow smartphone users to establish and manage specific profiles for lighting devices—specific combinations of luminosity, viewing angle, color and / or lighting pattern. The user may select different profiles to match different callers. Such an application further enhances the user experience by controlling the lighting device in a manner somewhat similar to how ringtones are managed for smartphones.

  Furthermore, since the lighting device may be used as a signal for the computer device to which the lighting device is connected, other programs or applications used by the computer device can be integrated into the lighting device. For example, a lighting device can be set up when playing a predetermined game, the lighting device is turned on, and the light intensity, viewing angle, color and / or lighting pattern changes as the game progresses. A similar realization is possible for music. The predetermined light profile may be integrated into the music program of the computing device, so that, for example, the light flashes rhythmically when playing music.

  Although the present invention has been described with a certain degree of particularity, it is to be understood that this disclosure is by way of example only, and that many variations in part structure and arrangement details may be made without departing from the spirit and scope of the invention. Should be understood.
