Abstract

A professional grade lighting apparatus may include a base panel that is flexible and has a reflector surface and a holding panel that is flexible and formed of a transparent and/or translucent material. A plurality of commercially available LED strips may be placed within pockets. The base panel may be fixed to the holding panel at a plurality of attachment locations that define hinges permitting relative pivotal motion.

Claims

1. A professional grade lighting apparatus for use with an associated electrical supply, the professional grade lighting apparatus comprising:

a base panel that is flexible and comprises a reflector surface;

a holding panel that is flexible and formed of a transparent and/or translucent material;

a plurality of commercially available LED strips each comprising;

(1) first and second opposite ends;

(2) electrical circuitry;

(3) electric wiring that extends from each end;

(4) a first side from which LED light is emitted; and

, (5) a second side opposite the first side;

an electric supply connector that electrically connects to the associated electrical supply and to the electric wiring of the LED strips;

wherein the base panel is fixed to the holding panel at a plurality of attachment locations that define hinges permitting relative pivotal motion;

wherein pockets are defined as spaces that are;

(1) between juxtaposed attachment locations; and

, (2) between the base panel and the holding panel;

wherein each pocket has opposite open ends;

wherein each LED strip is positioned within a pocket with;

(1) the electric wiring at each end accessible through the corresponding pocket open end;

(2) the first side in physical contact with the holding panel; and

, (3) the second side in physical contact with the reflector surface of the base panel;

wherein the electric wiring at the first ends of the LED strips are electrically interconnected;

wherein the electric wiring at the second ends of the LED strips are electrically interconnected;

wherein the electric supply connector supplies power from the associated electrical supply to illuminate the LED strips within the pockets to emit the LED light through the holding panel at sufficient lumens for use as a professional grade photographic lighting panel;

wherein each LED strip is designed to be selectively independently removable from its electric wiring and from at least one of its corresponding pocket open ends;

wherein juxtaposed pockets, and thus juxtaposed LED strips, are pivotal relative to each other about their neighboring hinge; and

,

wherein the professional grade lighting apparatus is designed to be adjusted between;

(1) a first configuration comprising a rolled-up panel configuration; and

, (2) a second configuration comprising a flat configuration.

2. The professional grade lighting apparatus of claim 1 wherein:

the base panel comprises one or more mounting means designed to selectively engage with a lighting apparatus holding device.

3. The professional grade lighting apparatus of claim 2 wherein:

the mounting means is designed to couple a first professional grade lighting apparatus to a second professional grade lighting apparatus.

4. The professional grade lighting apparatus of claim 1 wherein:

the pockets have longitudinal axes that are parallel.

5. The professional grade lighting apparatus of claim 1 wherein:

each pocket is sized and shaped to receive only one LED strip.

6. The professional grade lighting apparatus of claim 1 wherein:

each pocket is sized and shaped to alternatively receive each LED strip.

7. The professional grade lighting apparatus of claim 1 wherein:

the base panel is sewed to the holding panel at each of the plurality of attachment locations.

8. The professional grade lighting apparatus of claim 1 wherein:

each attachment location falls on a straight line.

9. The professional grade lighting apparatus of claim 1 further comprising:

first and second enclosing ends that are operable to enclose the open ends of the pockets.

11. The professional grade lighting apparatus of claim 1 wherein:

when the lighting apparatus is in the flat configuration, a portion of the holding panel forming each pocket is U-shaped.

10. The professional grade lighting apparatus of claim 10 wherein:

the first and second enclosing ends comprise hook and loop fasteners.

12. A method of assembling a professional grade lighting apparatus that can be used with an associated electrical supply, the method comprising the steps of:

(A) providing a base panel that is flexible and comprises a reflector surface;

(B) providing a holding panel that is flexible and formed of a transparent and/or translucent material;

(C) providing a plurality of commercially available LED strips each comprising;

(1) first and second opposite ends;

(2) electrical circuitry;

(3) electric wiring that extends from each end;

(4) a first side from which LED light is emitted; and

, (5) a second side opposite the first side;

(D) providing an electric supply connector;

(E) fixing the base panel to the holding panel at a plurality of attachment locations that define hinges permitting relative pivotal motion;

(F) defining pockets as spaces that;

(1) are between juxtaposed attachment locations;

(2) are between the base panel and the holding panel; and

, (3) have opposite open ends;

(G) positioning each LED strip within a pocket with;

(1) the electric wiring at each end accessible through the corresponding pocket open end;

(2) the first side in physical contact with the holding panel;

(3) the second side in physical contact with the reflector surface of the base panel;

(4) the electric wiring at the first ends of the LED strips electrically interconnected; and

, (5) the electric wiring at the second ends of the LED strips electrically interconnected;

wherein the professional grade lighting apparatus is designed, when assembled, to perform the following steps;

(H) electrically connecting the electric supply connector to the associated electrical supply and to the electric wiring of the LED strips to power the LED strips to provide professional grade photographic lighting;

(I) selectively independently removing each LED strip from its electric wiring and from at least one of its corresponding pocket open end;

(J) pivoting juxtaposed pockets, and thus juxtaposed LED strips, relative to each other about their neighboring hinge; and

,

(K) adjusting the professional grade lighting apparatus between;

(1) a first configuration comprising a rolled-up panel configuration; and

, (2) a second configuration comprising a flat configuration.

13. The method of claim 12 further comprising the step of:

providing the base panel with one or more mounting means designed to selectively engage with a lighting apparatus holding device.

14. The method of claim 13 wherein:

the mounting means is designed to couple a first professional grade lighting apparatus to a second professional grade lighting apparatus.
