         [0002]    This application incorporates by reference the disclosure of U.S. Design Patent Application No. 29/493597, entitled Personal Video Conference Lighting Assembly, filed on Jun. 11, 2014, as if fully restated herein. 
     
    
     BACKGROUND OF THE INVENTION 
       [0003]    1. Field of the Invention 
         [0004]    The invention relates in general to a lighting assembly and, more particularly, to a lighting assembly to be used for, among other things, personal video conferencing and video streaming applications—such as, but not limited to, Internet video streaming applications. 
         [0005]    2. Description of Related Art 
         [0006]    As personal computing devices—such as desk top computers, lap top computers, notebook computers, tablet computers, smart phones, as well as others—become smaller, less costly, and more powerful, their use proliferates. Many of personal computing devices are usable with external video cameras, or themselves include integrated video cameras. 
         [0007]    Additionally, as global information networks—such as the Internet—proliferate, individuals, government organizations, and businesses increasingly are using personal computing devices for video conferencing. Video conferencing quickly is becoming a common mode of communication, as it allows participants in remote locations to meet and converse with one another as if they were present in the same room. Such video conferences may involve conversations between individuals, or conferences between groups, and may include, without limit, topics such as personal activities, commerce, academics, or telemedicine. 
         [0008]    In any setting, proper lighting makes a tremendous difference in how people appear, and thus how they communicate, during a video conference or distance education session. Typical indoor ambient lighting—such as in an office or home setting—can be inadequate for video conferencing. Improper lighting can create harsh shadows during video conferencing, or otherwise hide or obscure the nuances of facial expression, eye-contact, or other critical aspects of non-verbal communication. Thus, proper lighting, which helps to convey these features, is important for effective communication. This is especially important, as the Internet allows speakers of different languages to interact with each other via videoconferencing applications. 
         [0009]    Additionally, as personal computing devices become smaller and more portable, the need exists for a small, portable lighting assembly. Such an assembly allows users to engage in video conferencing easily, with effective lighting, anywhere an Internet connection is available. Moreover, given the typical proximity of the user&#39;s eyes to the video camera of a personal computing device during personal video conferencing, it is desirable that a lighting assembly would be configured to minimize eye strain or user discomfort. 
       SUMMARY OF THE INVENTION 
       [0010]    Generally provided herein is a personal video conference lighting assembly that is lightweight, portable, and provides sufficient illumination to portray nuances of facial expression, eye-contact, or other critical aspects of non-verbal communication. The personal video conference lighting assembly provides lighting sufficient for a variety of personal video conferencing applications, such as personal communications, business, distance learning, and telemedicine. In a non-limiting embodiment, the personal video conference lighting assembly engages easily with a personal computing device and is easily operated by a user. Desirably, the personal video conference lighting assembly also provides high-quality illumination that minimizes eye strain and user discomfort. 
         [0011]    Disclosed herein is a lighting assembly for use with personal computing devices. According to an embodiment, the lighting assembly includes a housing forming an interior cavity, in which a light emitting diode (LED) circuit board may be situated. At least one LED may be positioned to emit light through a front portion of the housing to illuminate the face of a user during video conferencing. Desirably, the LEDs may be configured to provide converging light that is continuous—minimizing hot spots and bands of illumination. In an embodiment, this may be accomplished through the use of optics, such as beam shaper optics. Thus, user eye strain and discomfort may be minimized. Additionally, the intensity of the light and a user&#39;s ability to control the orientation of the LED housing in certain embodiments may further contribute to user comfort during use of the lighting assembly. 
         [0012]    In an embodiment, the housing may be connected to a neck that enables an orientation of the housing to be adjusted by the user. The neck may connect to a base unit. The base unit may have at least one support mechanism that allows the base unit to be positioned at a variety of angles. In a non-limiting embodiment, the support mechanism may include at least one rotatably-retractable leg unit. The base unit also may have a mechanism on its front portion to aid in the support of a personal computing device thereon. 
         [0013]    In another embodiment, the neck connects the LED housing to a clipping mechanism that engages a personal computing device without a base unit. In accordance with another embodiment, the housing connects to the clipping mechanism without the use of a neck. These embodiments may allow the user to adjust the orientation of the housing without moving the personal computing device, or the housing may remain fixed with respect to the personal computing device. 
         [0014]    Various non-limiting embodiments of the present invention enable varying degrees of ease of mobility, allowing a user to move about freely and untethered during video conferencing, while maintaining adequate and consistent light levels for enhanced camera imaging. Thus, a user may use the lighting assembly to illuminate his or her facial features during video conferencing in a manner that provides high-quality imaging, while minimizing discomfort. 
         [0015]    These and other features and characteristics of the present invention, as well as the methods of operation and functions of the related elements of structures and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures. As used in the specification and the claims, the singular form of “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise.

In an embodiment at least one substantially transparent or translucent cover portion  68  may be placed holes  64  in front portion  21  of LED housing  20  between optics  63  and a user. Cover portion  68  may protect optics  63  from scratching or other damage. In an embodiment, cover portion  68  may help to shape the light emitted by LEDs  61 , as further described below. 
         [0062]    An embodiment of optics  63  is depicted in  FIGS. 11A-11C . Optics  63  may shape the light emitted by LEDs  61 . Light emitted by LED  61  enters optic  63  at an LED-side  65 , travels through optics  63 , and exits optics at observer-side surface  66 . In an embodiment, optics  63  shape or narrow the rays of light emitted by LEDs  61 , so that the beams converge on a user.  FIG. 13A  depicts an example of a LED housing  20 , in which light is emitted by LEDs  61  through holes  64  in front portion  21  of LED housing  20 , and wherein optics  63  are not included.  FIG. 13B  shows the shaping of light rays in an embodiment of the present invention wherein an embodiment of optics  63  is included between LEDs  61  and a user. Optics  63  may provide continuous light coverage over a user, while minimizing bright points or “hot spots” on the user. Optics  63  also may reduce bands of bright areas, which may occur in other configurations, such as when light emitted by LEDs  61  do not pass through optics  63 , as described above. Thus, embodiments of assembly  10  which include optics  63  may provide high-quality illumination, and may decrease eye strain and user discomfort, during video conferencing. The beam shape may be optimized by adjusting the distance of optics  63  from LEDs  61  during fabrication of assembly  10 . In an embodiment observer side surface  66  of optics  63  is positioned about six millimeters from LEDs  61 . In an embodiment seen in  FIG. 10B , optics  63  may possess a clearance space  69  configured to receive an LED  61 , so that the optical medium surrounds the surface of LED  61  from which light is emitted. Optics  63  may be substantially clear, and may include a frosted finish. In a further embodiment, optics  63  are not colored diffuser lenses. Optics  63  may be comprised of polycarbonate, or other material in the art known to possess the optical qualities necessary for shaping light emitted by LEDs  61 . Optical surfaces of optics  63  may possess an optical polish. Embodiments of optics  63  may include total internal reflection (“TIR”) lenses. An embodiment of optics  63  may comprise multiple media with different optical properties, such as different indices of refraction. 
         [0063]    With reference to  FIGS. 11B-11C , embodiments of optics  63  may include a support structure  67  to aid in proper placement over LEDs  61 . A non-limiting example of optics  63  is the Carclo® model 10413 10 mm square medium frosted optic, available from Carclo Optics in Latrobe, Pa. However, it should be understood that other optics known in the art to shape beams of light to provide continuous light coverage on a user, while minimizing bright points or “hot spots” on the user, may be used as well. 
         [0064]    In another embodiment, a user&#39;s ability to adjust the orientation of LED housing  20 , and to control the intensity of light emitted from LEDs  61 , further may contribute to user comfort and quality of illumination for video conferencing.
