DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0021] Referring to FIG. 1, the light panel 10 is shown to be flanked by a right side light panel 12 and a left side light panel 16 with a first hinge 16 and a second hinge 18 that allow the light panels 12 and 14 to be folded onto the center panel 20. The center panel has its interior components and certain LEDs housed in a housing 21, with the corresponding housings 13 and 15 for the side panels, respectively. Mounting hardware 22 allows the panel to be connected to a tripod or other mounting structures. Electrical connections can be provided through the connector 24.

[0022] FIG. 2 shows the unfolded light panel from the rear view thereof showing that each of the panels at the rear comprises respective heat dissipating fins 26a, 26b and 26c, respectively for the panels 20, 12 and 14. The electrical connector 24 is located on a bottom side of the center panel 20 and the mounting hardware 22 has a tightening knob 22a that presses a bar against a surface of the panels to maintain a desired orientation thereof.

[0023] FIG. 3 shows the three-part light panel 10 from the front side thereof with the light emitting side covered by respective, filters 28a, 28b and 28c that may be removable at will in accordance with an embodiment of the invention.

[0024] As shown in FIG. 4, the filters 28a, 28b and 28c can be slid away by releasing a portion of the panel housing exposing underneath the light emitting diodes for the three LED panels, namely LED matrices 30a, 30b and 30c.

[0025] In FIG. 5, the entire array of LEDs can be seen owing to the total removal of the removable filters.

[0026] FIG. 6 shows an end view from the top showing the electrical connector and the attaching mechanism with the knob 22a and also the two panels 12 and 14 partially bend at an angle that meets the center panel 20 at an angle greater than 90° which will create a particular lighting pattern which can be changed by adjusting the positions of the side panels 12 and 14. In an embodiment, a tightening mechanism can be provided to assure that the position and holding power of the hinges can maintain the folded/angular orientations of the panels of the overall light panel 10 as desired.

[0027] In FIG. 7, the center light panel 20 is partially covered over by the side light panel 14 while the side panel 12 is partially unfolded creating a desired lighting pattern.

[0028] In accordance with preferred embodiments, the light panels 12, 14 and 16 may have width and length dimensions of 60-70 mm and 165-175 mm, respectively. Alternatively, the center panel 10 may be larger than the side panel, preferably twice as large, so that the side panels are foldable over and configured to cover the center panel in the folded position.

[0029] As will be apparent to one skilled in the art, the panel can come with various electrical controls for controlling the light emanating from the LEDs and the LEDs can be provided so as to be selectably powered to provide light of a color temperature that can be set in accordance with a user's needs for the particular application, as described in the prior art. In one embodiment, the LEDs out light at a 5600K (daylight) temperature.

[0030] FIG. 8 shows the side panels 12, 14 folded over presenting a total package size that can be easily stowed and transported by photographers and other users of the light panel of the present invention.

[0031] Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claim.
