Lighting system for video conferencing
View Patent ↗A lighting system for video conferencing includes a reflector structure positioned in an enclosure and having one or more light sources positioned therein to reflect light in a selected direction. A diffuser lens plate overlies the reflector structure to diffuse light emanating from the reflector structure. The reflector structure may include a plurality of parabolic reflectors having the shape of circular paraboloids. The light sources may include LED's positioned at the parabolic foci of the reflectors. The diffuser lens plate is translucent and may be colored yellow to filter light from the LED's. The diffuser has a surface texture which diffuses light from the LED's.
1. A lighting system for illumination of a person's face for video imaging thereof and comprising:
(a) a parabolic reflector structure including a plurality of intersecting parabolic reflectors connected by webs; each parabolic reflector having a circular paraboloid shape, a parabolic axis, and a parabolic focus; and the parabolic axes of said reflectors being fixed in substantially parallel relation and in a common plane;
(b) a plurality of light emitting diodes (LED's), each LED being mounted substantially at the parabolic focus of an associated parabolic reflector;
(c) a colored diffuser lens plate overlying said parabolic reflector structure whereby light from said LED's passes through said lens plate;
(d) a power connection coupled to said LED's to enable connection of a power source thereto to cause illumination of said LED's;
(e) a light unit enclosure having said reflector structure, said LED's, said diffuser lens plate, and said power connection mounted therein; and
(f) an attachment member positioned on said enclosure to enable securing said enclosure to a computer device having a video camera associated therewith.
2. A system as set forth in claim 1 and including:
(a) a pair light unit enclosures, each enclosure having a reflector structure, an LED, a diffuser lens plate, and a power connection mounted therein, and having an attachment member positioned thereon; and
(b) said light unit enclosures being secured in spaced relation to a computer device having a video camera associated therewith.
3. A system as set forth in claim 1 wherein said attachment member includes:
(a) a component of a hook and loop fastener secured to said enclosure.
4. A light unit as set forth in claim 1 wherein:
(a) said diffuser lens plate is translucent and yellow colored.
5. A light unit as set forth in claim 1 wherein:
(a) said diffuser lens plate includes a surface texture formed by a plurality of small, aligned, substantially frusto-cylindrical bumps.
6. A lighting system for illumination of a person's face for video imaging thereof and comprising:
(a) a parabolic reflector structure including a plurality of intersecting parabolic reflectors connected by webs; each parabolic reflector having circular paraboloid shape, a parabolic axis, and a parabolic focus; and the parabolic axes of said reflectors being fixed in substantially parallel relation and in a common plane;
(b) a plurality of light emitting diodes (LED's), each LED being mounted substantially at the parabolic focus of an associated parabolic reflector;
(c) a translucent yellow colored diffuser lens plate overlying said parabolic reflector structure whereby light from said LED's passes through said lens plate;
(d) said diffuser lens plate including a surface texture formed by a plurality of small, aligned, substantially frusto-cylindrical bumps;
(e) a power connection coupled to said LED's to enable connection of a power source thereto to cause illumination of said LED's;
(f) a light unit enclosure having said reflector structure, said LED's, said diffuser lens plate, and said power connection mounted therein; and
(g) an attachment member positioned on said enclosure to enable securing said enclosure to a computer device having a video camera associated therewith.
7. A system as set forth in claim 6 wherein said attachment member includes:
(a) a component of a hook and loop fastener secured to said enclosure.
