Title: Adjustable mounted portable light

Description:
BACKGROUND 
     Field 
     Embodiments of the present disclosure generally relate to a mountable device assembly, and more particularly, to a mountable lighting device assembly. 
     Description of the Related Art 
     Remote video conferencing and live streaming has become more popular in recent years, due in large part to the declining costs of video generating equipment, the proliferation of high-speed Internet, and a global movement towards remote work situations. As familiarity with remote video conferencing and live streaming increases, so does demand for more sophisticated camera devices, such as a webcam, and adequate lighting to properly capture images. A light source for proper image capturing may not be readily available, or may be large, heavy, and inconvenient for the use in remote video conferencing conducted on a laptop, a tablet, or other portable electronics devices. Thus, a portable light that can be positioned with a webcam has become a common demand for video conference users. 
     However, for proper lighting, a location of a portable light needs to be adjusted in relation to other objects, such as a screen of a computer monitor, a user with or without glasses that is positioned in a remote video conference environment, other light sources, and/or walls near the computer monitor. For example, if a portable light is positioned in an inappropriate position above or on a side of a user that is wearing glasses, a captured image may contain glare from the glasses. If a portable light is positioned on one side of a user, a captured image may include undesirable shadows on an opposing side of the user. If a portable light is positioned in front of a screen of a computer monitor, a captured image and/or the computer screen itself may contain glare generated by the light source in the portable light. If a portable light is positioned in front of the lens of a camera device, a captured image may contain “lens flare” due to the light source in the portable light being in or near the field of view of the camera device. Lens flare is typically caused when stray light reaches the sensor in the camera due to reflections at the air-glass interface of the lens or due to light scattering in the lens. Such glare may also cause eye strain for a user. 
     Accordingly, there is a need in the art for a light source that has a mount that is adjustable and configurable to allow the light source to be mounted and positioned, in any possible video conferencing or livestreaming environment, so that the light source avoids the problems described above.

     DETAILED DESCRIPTION 
     Embodiments of the present disclosure generally relate to a mountable device assembly, and more particularly, to a mountable lighting device. 
     The embodiments described below provide systems and methods for placing devices, such as portable lights and other peripherals, on a mounting surface, such as a monitor display. In some embodiments, the mounting surface includes a portion of a laptop or tablet that includes a built-in display, a cathode-ray tube (CRT) monitor, a light emitting diode (LED) monitor, a liquid crystal display (LCD) monitor, an organic light-emitting diode (OLED) monitor, a plasma display monitor. The mountable device assembly according to the embodiments described below can be location adjustable and can place a portion of the mountable device assembly at a desired height from the mounting surface, a desired distance behind a back of the mounting surface, and at a desired angle relative to the mounting surface. In addition, the mountable device assemblies described herein can also be held in the hand and allows the device to be used as a hand-held device. 
       FIGS. 1A, 13, and 1C  are a side view, a rear view, and a front view, respectively, of one configuration of a mountable device assembly, which is referred to herein as a portable light  100 . The portable light  100 , as illustrated in  FIGS. 1A, 1B , and  1 C, is positioned in an extended configuration.  FIGS. 1D, 1E, and 1F  are a side view, a rear view, and a front view, respectively, of the portable light  100 , in a fully retracted configuration. The portable light  100  includes a mount  102  and a housing  104  disposed on and/or coupled to the mount  102 . The mount  102  includes a first linkage  106  having a front face  106 F ( FIG. 1A ) and side faces  106 S,  106 S′ ( FIG. 1B ) each connected to the front face  106 F, and a second linkage  108  having a body portion  110  and a neck portion  112 . The body portion  110  of the second linkage  108  is slidably connected to the first linkage  106  and can slide in and out of the first linkage  106  through a top edge  106 T of the first linkage  106  in the Z direction. As described herein, the mount  102  may be considered to be in a “fully extended” configuration, for example, when the body portion  110  of the second linkage  108  is substantially extended from the top edge  106 T of the first linkage  106 , and in a “fully retracted” configuration, for example, when the body portion  110  of the second linkage  108  is substantially retracted within a space formed within the first linkage  106 . The first linkage  106  may have a bottom wall  106 B, and thus the first linkage  106  acts as a case in which the body portion  110  of the second linkage  108  fits when it is positioned in the fully retracted configuration. In some embodiments, the first linkage  106  has a friction pad  106 P on the front face  106 F near or adjacent to the bottom wall  106 B. The friction pad  106 P is formed from a compliant material that is configured to prevent the first linkage  106  from sliding against a surface on which the portable light  100  mounted, for example, a monitor display as shown in  FIGS. 6A and 6B  below. In one example, the friction pad  106 P is formed from a low durometer polymer and/or high friction material, such as a rubber or other polymeric material. Also as described herein, a direction referred to as “front” or “forward” may be understood as towards a front face  110 F of the body portion  110  of the second linkage  108  from a rear face  110 R of the body portion  110  of the second linkage  108  in the X direction, and a direction referred to as “rear,” “rearward,” “back,” or “behind” may be understood as towards the rear face  110 R of the body portion  110  of the second linkage  108  from the front face  110 F of the body portion  110  of the second linkage  108  in the X direction, A direction referred to as “top,” “upwards,” and “above” may be understood as towards the top edge  106 T of the first linkage  106  from the bottom wall  106 B of the first linkage  106 , and a direction referred to as “bottom,” “downwards,” and “below” may be understood as towards the bottom wall  106 B of the first linkage  106  from the top edge  106 T of the first linkage  106 . 
     The first linkage  106  may have a length H 1  ( FIG. 1B ) in the Z direction of between about 100 mm and about 700 mm, such as between about 100 mm and about 350 mm, or between about 100 mm and about 260 mm, for example, about 151 mm. The first linkage  106  may have a thickness ( FIG. 1A ) of between about 5 mm and about 60 mm, such as between about 5 mm and about 30 mm, for example, about 12 mm. The first linkage  106  may also have an inner width W 1  ( FIG. 1B ) in the Y direction of between about 20 mm and about 250 mm, such as between about 20 mm and about 50 mm, for example, about 47 mm. The body portion  110  of the second linkage  108  may have a length H 2  ( FIG. 1B ) in the Z direction of between about 100 mm and about 720 mm, such as between about 120 mm and about 370 mm, for example, about 174 mm. The body portion  110  of the second linkage  108  may have a thickness L 2  ( FIG. 1A ) in the X direction of between about 5 mm and about 60 mm, such as between about 5 mm and about 30 mm, for example, about 8.5 mm. The body portion  110  of the second linkage  108  may have a width W 2  ( FIG. 1B ) in the Y direction of between about 20 mm and about 250 mm, such as between about 15 mm and about 50 mm, for example, about 43 mm. Thus, an overall length H E  ( FIG. 1B ) of the first linkage  106  and the body portion  110  of the second linkage  108  combined in a fully extended configuration is between about 176 mm and about 576 mm, for example, about 233 mm, and an overall length H R  ( FIG. 1E ) of between about 118 mm and about 368 mm, for example, about 177 mm, in a fully retracted configuration. 
     The mount  102  further includes a third linkage  114  ( FIG. 1A ) that is rotatably attached to the first linkage  106  via a hinge  116  at the top edge  106 T of the first linkage  106 . The third linkage  114  can rotate about an linkage axis that is parallel to the Y-axis, between an open configuration ( FIGS. 1A and 2B ), in which the third linkage  114  extends outwardly from the front face  106 F of the first linkage  106  substantially perpendicular to the front face  106 F of the first linkage  106  in the +X direction, and a closed configuration ( FIG. 2E ), in which the third linkage  114  extends downwardly towards the bottom wall  106 B of the first linkage  106  in the −Z direction. The third linkage  114  in the open configuration is illustrated in  FIGS. 1A and 1D , as an example. In some embodiments, the hinge  116  is configured such that rotational motion between a portion of the third linkage  114  and a portion of the first linkage  106  is inhibited by friction (or by use of an additional torsional spring (not shown)) created between these linkage portions due to an interference fit between these parts. By adjusting the friction created between the portion of the third linkage  114  and the portion of the first linkage  106  to a desired amount during the design and manufacturing process, the position of the third linkage  114  relative to the first linkage  106  can be set and maintained at a desired angle between the third linkage  114  and the first linkage  106  during use. In some embodiments, the angle between the third linkage  114  and the first linkage  106  is fixed at about 0° (in the closed configuration) or about 90° (in the open configuration). 
     The mount  102  further includes a telescoping element  118  that is slidably connected to the third linkage  114 , as shown in  FIGS. 1A, 2A, 2B, and 2E . The telescoping element  118  includes an abutment portion, such as a lip portion  120 , disposed at an end  118   a  of the telescoping element  118  opposite to the top edge  106 T of the first linkage  106  in the X direction. The lip portion  120  extends substantially in a direction perpendicular to the third linkage  114  from the top edge  106 T of the first linkage  106  towards the bottom wall  106 B of the first linkage  106 . In some embodiments, the lip portion  120  is fixed at an angle of less than 90° from the telescoping element  118 . In some other embodiments, the lip portion  120  is connected to the telescoping element  118  via a friction hinge (not shown), which may include one or more detents (not shown), that allow positioning of the lip portion  120  at a variable angle with respect to the telescoping element  118  variable. 
     The neck portion  112  of the second linkage  108  is positioned at an end of the body portion  110  of the second linkage  108  opposite to the first linkage  106  in the Z direction. The neck portion  112  is inclined at an angle in the Z-X plane with respect to the body portion  110  of the second linkage  108  in the direction extending away from the front face  110 F of the body portion  110  of the second linkage  108  and towards the rear face  110 R of the body portion  110  of the second linkage  108 , and also away from the third linkage  114 . Thus, the neck portion  112  is disposed at the rear of the third linkage  114  (i.e., at a location further away from the front face  106 F of the first linkage in a direction (−X-direction) opposite to the direction the front face  106 F is facing). In some embodiments, an angle c formed between the neck portion  112  and the body portion  110  of the second linkage  108  is between about 0° and about 180°. 
     The housing  104  is movably attached to the neck portion  112  of the second linkage  108  via a housing attachment mechanism  124  disposed on a top surface  112 T of the neck portion  122  of the second linkage  108 . The top surface  112 T of the neck portion  122  of the second linkage  108  is continuous with the front face  110 F of the body portion  110  of the second linkage  108 . The housing attachment mechanism  124  allows the housing  104  to tilt about a tilt axis  126 T ( FIG. 1B ) in the Z-X plane and rotate about a rotation axis  126 R ( FIG. 1A ) that is perpendicular to the top surface  112 T of the neck portion  112  of the second linkage  108 . The housing attachment mechanism  124  is discussed in more details below in reference to  FIGS. 3A, 3B, and 3C . 
     The housing  104  may enclose therein a variety of related devices and peripherals known to those of skill in the art. For example, the housing  104  may include a portable light (not shown), electronic elements (not shown), a digital camera (not shown), a digital camera (not shown), and/or various hardware modules and the like that may be placed on a computer monitor. An example device that may be enclosed in the housing  104  is discussed in more details below in references to  FIG. 4 . In some embodiments, as shown in  FIGS. 1C and 1F , the housing  104  includes an outer casing  104 C and a lens  104 L. In one configuration, a device  400  ( FIG. 4 ), which is discussed further below, is positioned in an enclosed region (not shown) formed between the outer casing  104 C and the lens  104 L. In one example, the device  400  includes one or more light sources (e.g., array of light sources  402 ) that are configured to emit a plurality of wavelengths of light (e.g., white light) that pass through the lens  104 L in a direction that is normal to the front surface  104 F ( FIG. 1D ) of the lens  104 L, which, as shown in  FIG. 1D , is generally parallel to the X-Z plane. In some embodiments, the lens  104 L, due to features formed on one or more surfaces thereof, is configured to act as a diffuser that diffuses or scatters light to reduce the collimation of the emitted light and make the light transmitted from the housing  104  to appear “softer.” The act of diffusing the emitted light by the lens  104 L will reduce the chance of a noticeable reflection being generated off of one or more exposed surfaces (e.g., glasses of a user) within the environment surrounding the mount  102 . 
     Referring to  FIGS. 1A, 1B, and 5 , the mount  102  further includes an engagement mechanism that allows the body portion  110  of the second linkage  108  to slide in and out of the first linkage  106  in the Z direction when an external force (e.g., pushing or pulling) is applied in the Z-direction to the first linkage  106 , the second linkage  108 , or both. In some embodiments, the engagement mechanism of the mount  102  includes fins (also referred as “protrusion”)  128 ,  128 ′ ( FIGS. 1B and 5 ) formed on inner surfaces of the side faces  106 S,  106 S′ of the first linkage  106  and grooves  130 ,  130 ′ ( FIGS. 1A and 5 ), formed in outer surfaces of side faces  110 S,  110 S′ of the body portion  110  of the second linkage  108 . Due to friction created between components  106 C in the first linkage  106  and a ledge  108 L on the front face  110 F of the body portion  110  of the second linkage  108 , the relative position of the second linkage  108  and the first linkage  106  can be maintained at a desired location within the first linkage  106  when no external force is applied. 
     The mount  102  further includes a cable management system  132  on the rear face  110 R of the body portion  110  of the second linkage  108 , as illustrated in  FIGS. 1B and 1E . The cable management system  132  may be used to store a cable  134  connected to the housing  104 . The cable management system  132  is discussed in more details below in reference to  FIGS. 1B and 1E . 
       FIGS. 2A and 2B  are enlarged isometric views of a portion of the portable light  100  including the first linkage  106  and the third linkage  114  in a compressed configuration and in a released configuration, respectively, while the third linkage  114  is in the open configuration.  FIGS. 2C and 2D  are a top view and a side view of the third linkage  114  and the telescoping element  118 , respectively.  FIG. 2E  is an enlarged isometric view of a portion of the portable light  100  including the first linkage  106  and the third linkage  114  in a compressed configuration and in a released configuration, respectively, while the third linkage  114  is in the closed configuration. As described herein, the mount  102  may be considered to be in a “fully compressed” configuration, for example, when an end of the telescoping element  118  opposite to the lip portion  120  mates with a ledge portion  106 L of the first linkage  106 , and in a “fully released” configuration, for example, when a hard stop (not shown) formed in one end of the third linkage  114  is placed in contact with a hard stop (not shown) portion of the telescoping element  118  when the telescoping element  118  is moved to a position that is a distance away from the hinge  116 . As illustrated in  FIGS. 2A and 28 , in one example, the third linkage  114  extends outwardly from the front face  106 F of the first linkage  106  substantially perpendicular to the front face  106 F of the first linkage  106  in the X direction (i.e., in an open configuration). The telescoping element  118  includes end tabs  202  on both sides of the telescoping element  118 . The end tabs  202  are disposed outside of the third linkage  114  and engaged with side faces  114 S,  114 S′ of the third linkage  114 , when the telescoping element  118  is slidably connected to the third linkage  114 . The end tabs  202  allow the telescoping element  118  to telescope in and out on the third linkage  114  in the X direction. The third linkage  114  may have a length L 3  ( FIG. 2C ) in the X direction of between about 20 mm and about 80 mm, for example, about 40 mm, a width W 3  ( FIG. 2D ) in the Y direction of between about 20 mm and about 450 mm, for example, about 45 mm, and a thickness H 3  ( FIG. 2D ) in the Z direction of between about 2 mm and about 50 mm, for example, about 2 mm. The telescoping element  118  has a width W 4  ( FIG. 2D ) in the Y direction that is longer than the width W 3  ( FIG. 2D ) of the third linkage  114 , such that the third linkage  114  fits in the telescoping element  118 . The end tabs  202  each have a length H 4  ( FIG. 2D ) in the Z direction between about 3 mm and about 50 mm, for example, about 4.5 mm. Thus, an overall length L ( FIG. 2C ) of the third linkage  114  and the telescoping element  118  in the X direction can vary between about 42 mm and about 66 mm. 
       FIGS. 3A and 3B  are enlarged side views of a portion of the portable light  100  including the housing attachment mechanism  124 .  FIG. 3C  is a top view of the portable light  100 . The housing attachment mechanism  124  may take various forms, such as a hinge or a ball joint, and allows the housing  104  to tilt about the tilt axis  126 T in the Z-X plane and rotate about the rotation axis  126 R. In the example illustrated in  FIG. 3 , the housing attachment mechanism  124  includes a ball socket pin  302  disposed on the neck portion  122  of the second linkage  108 , and a recessed socket joint  304  formed in the housing  104 . Thus; the housing  104  can rotate about the ball socket pin  302 . In some other embodiments, this arrangement can be reversed, or otherwise modified. For example, a ball socket pin  302  may be disposed on the housing  104  and a recessed socket joint  304  may be disposed on the neck portion  122  of the second linkage  108 . In some embodiments, the housing  104  can rotate up to 360° about the rotation axis  126 R. The housing attachment mechanism  124  further includes an axial friction hinge  306  that allows the housing  104  to tilt about the tilt axis  126 T in the Z-X plane. An angle β of the housing  104  with respect to the Z axis can be varied between about 90° and about 360°, such as between about 90° and about 210°. 
       FIG. 4  is a simplified block diagram of a device  400 , which may be included in the portable light  100 , for example, enclosed within the housing  104 . The device  400  may include various standard modules, such as an array of light sources  402  (e.g., light emitting diodes), a heat shield  404 , a printed circuit board (PCB)  406 , a universal serial bus (USB) port  408 , and a battery  410 . In some embodiments, the device  400  may optionally include an antenna  412 , a processor  414  and a cache memory  416  that are coupled to the printed circuit board (PCB)  406 , and are adapted to control one or more activities performed by the device  400 . In one example, the optional elements are configured to control and adjust the amount and timing of the delivery of the light emitted by the array of light sources  402  based on a signal received through the USB port  408  or wireless signal (e.g., Bluetooth®, Bluetooth® LE, NFC, etc.) received by the antenna  412 . The battery  410  may be used to power the array of light source  402  and the other components of the device  400 , such as the antenna  412  formed on the PCB  406 . The battery  410  may be a rechargeable battery and recharged via a cable, such as the cable  134 , connected to the USB port  408  on the PCB  406 . The USB port  408  may be a standard size, a micro size, or a mini size. Alternatively, other ports such as a proprietary port (not shown) may be used. The heat shield  404  may be placed between the battery  410  and the PCB  406 . The device  400  may include various standard electronic modules that are well known in the art and are not described in detail herein, 
       FIG. 5  is a cross sectional view of the first linkage  106  and the body portion  110  of the second linkage  108 , illustrating the engagement mechanism between the first linkage  106  and the second linkage  108 . As illustrated, the fin  128  protrudes from the inner surface of the side face  106 S of the first linkage  106  in the X direction, and the fin  128 ′ protrudes from the inner surface of the side face  106 S′ of the first linkage  106  in the X direction. The groove  130  is formed in the outer surface of the side face  110 S of the body portion  110  of the second linkage  108  in the X direction, and the groove  130 ′ is formed in the outer surface of the side face  110 S′ of the body portion  110  of the second linkage  108  in the X direction. When in use, the fin  128  engages with the groove  130 , and the fin  128 ″ engages with the groove  130 ′, thus allowing the first linkage  106  and the body portion  110  of the second linkage  108  to slide with respect to each other in the Z direction when an external force in the Z direction is applied to one or both of the first linkage  106  and the second linkage  108 , and to be held in place when no external force in the Z direction is applied. 
     For example, each of the fins  128 ,  128 ′ may have a length of between about 50 mm and about 650 mm, such as between about 50 mm and about 300 mm, or between about 50 mm and about 210 mm, for example, about 110 mm in the Z direction ( FIG. 1A ), a width of about 3.5 mm in the X direction ( FIG. 5 ), and a depth of about 0.7 mm in the Y direction ( FIG. 5 ). Each of the grooves  130 ,  130 ′ may have a length of between about 60 mm and about 680 mm, such as between about 80 mm and about 330 mm, for example, about 135 mm, in the Z direction ( FIG. 1A ), a width of about 0.7 mm, in the X direction ( FIG. 5 ), and a depth about 0.7 mm in the Y direction ( FIG. 5 ). 
     Referring to  FIGS. 1B and 1E , a cable management system  132 , which is a recess  136  formed on the rear face  110 R of the body portion  110  of the second linkage  108 , is configured such that a cable, such as the cable  134 , can be rolled and stored within the recess  136 . In some embodiments, the cable management system  132  includes one or more protrusions  138  on a rear cover  140 , as illustrated in  FIGS. 1G and 1H , such that a cable, such as the cable  134 , can be snapped in the one or more protrusions  138 .  FIGS. 1G and 1H  are rear views of the portable light  100 , in an extended configuration and in a fully retracted configuration, respectively. It should be noted that the cable management system  132  is disposed on the second linkage  108 , to which the housing  104  is connected. Thus, a distance between the housing  104  and the cable management system  132  is unchanged when the second linkage  108  is positioned relative to the first linkage  106  in an extended configuration, as illustrated in  FIG. 1B , and in a retracted configuration, as shown in  FIG. 1E . This configuration thus allows the second linkage  108  to slide in the Z direction with respect to the first linkage  106  without causing stress or tension in a portion of the cable stored in the cable management system  132  and the portion of the cable attached to the USB port  408  formed in the housing  104 . 
       FIGS. 6A and 6B  illustrate an exemplary use of the portable light  100 . As illustrated, the portable light  100  is placed on a monitor display  602  (e.g., a laptop or tablet that includes a built-in display, a CRT monitor, a LED display, a LCD monitor, an OLED monitor, a plasma display monitor), by placing the third linkage  114  on a top edge  402 T of the monitor display  602 , the lip portion  120  of the telescoping element  118  on a front face  602 F of the monitor display  602 , and the bottom wall  106 B of the first linkage  106  on a rear face  602 R of the monitor display  602 . The friction pad  106 P and another friction pad (not shown) disposed on the lip portion  120  are configured to inhibit the bottom wall  106 B of the first linkage  106  from sliding against the rear face  602 R of the monitor display  602 . Another device  604 , such as a webcam, may be also placed on the monitor display  602 . Thus, the housing  104  can be placed behind and above the monitor display  602 . The neck portion  112  of the second linkage  108  is positioned a distance D behind the rear face  602 R of the monitor display  602  (i.e., a distance between the neck portion  112  of the second linkage  108  and a plane including the front face  602 F of the monitor display  602  illustrated as the dotted line), and the neck portion  112  is also positioned a height H above the top edge  602 T of the monitor display  602 , which can both be adjusted by adjusting: 1) the position of the body portion  110  of the second linkage  108  relative to the first linkage  106 , 2) an angle γ between the first linkage  106  and the third linkage  114 , and/or 3) the position of the telescoping element  118  relative to the third linkage  114 . For example, an overall length of the first linkage  106  and the body portion  110  of the second linkage  108  can range between about 118 mm and about 576 mm, and a length L 3  of the third linkage  114  is between about 20 mm and about 80 mm, the angle γ between the first linkage  106  and the third linkage  114  can range between about 0° and about 90°, and an overall length L of the third linkage  114  and the telescoping element  118  can range between about 42 mm and about 66 mm. Therefore, the neck portion  112  of the second linkage  108  is positioned behind the rear face  602 R of the monitor display  602 . The distance D of the neck portion  112  of the second linkage  108  behind the rear face  602 R of the monitor display  602  can vary between about 0 mm and about 80 mm, and the height H of the neck portion  112  of the second linkage  108  above the top edge  602 T of the monitor display  602  can range between about 0 mm and about 120 mm. The monitor display  602  may have a thickness of between about 3 mm and about 62 mm. 
     In some embodiments, the portable light  100  can be used as a hand-held device. The first linkage  106  can be held in the hand. For a user&#39;s comfort when holding the first linkage  106 , the portable light  100  may be used in an open configuration, in which the third linkage  114  extends outwardly from the front face  106 F of the first linkage  106  substantially perpendicular to the front face  106 F of the first linkage  106  in the X direction. 
     In the embodiments described herein, systems and methods for placing devices, such as portable lights and other peripherals including webcams, on a monitor display, such as a laptop or tablet that includes a built-in display, a cathode-ray tube (CRT) monitor, a light emitting diode (LED) monitor, a liquid crystal display (LCD) monitor, an organic light-emitting diode (OLED) monitor, a plasma display monitor, are provided. Mountable device assemblies according to the embodiments described herein can be location adjustable and can place a device at a desired height from the monitor display, a desired distance behind the back of the monitor display, and at a desired angle relative to the monitor display. The mountable device assemblies described herein can also be held in the hand and allows the device to be used as a hand-held device. 
     While the foregoing is directed to embodiments of the present disclosure, other and further embodiments of the disclosure may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
