Abstract: A softbox speedring is provided to reduce the manufacturing costs through a simple structure, to be simply repaired, and allow the rapid folding and spreading of a pole shaft. A softbox speedring having a fitting assembly structure includes a speedring body including a central hole formed at a center of the speedring body, a plurality of adaptor inserting holes formed along an outer circumferential surface of the speedring body, and rotational shaft seating grooves formed in first perpendicular surface and second perpendicular surface of each adaptor inserting hole, and an adaptor including a head part including rotational shafts protruding from opposite perpendicular surfaces of the head part to be fitted into and assembled with the rotational shaft seating grooves, and a body part provided at a lower portion of the head part and including a pole inserting part formed in a lower end of the body part.

Abstract: An automatic illumination control apparatus for adjusting an output of an illumination device depending upon a distance between a subject and the illumination device, includes: a distance measuring sensor installed at a position close to the illumination device to measure distance information between the illumination device and the subject; and an illumination managing unit configured to generate a management signal including an illumination intensity of illumination which is outputted from the illumination device according to the distance information, and send the management signal to the illumination device. With the present invention, even though the subject comes toward or away from the main illumination device and thus the distance between the subject and the illumination is changed, the illumination intensity indicative of the subject and the space around the subject and the color temperature can be constantly maintained, thereby obtaining the still picture or the motion picture with constant quality.

Abstract: A collapsible lighting device having circuit wires and LED modules and a method for manufacturing the same wherein the lighting device is collapsible in every direction, thereby being easy to be carried and stored, and makes use of the LED modules, thereby reducing an amount of power consumed. The collapsible lighting device includes: a main sheet formed of fibers made of a soft material collapsible with no directionality and an electrical insulation material for insulating electricity flowing along circuit wires, the fibers being resistant to a temperature greater than 250° C.; LED modules mounted on the main sheet in such a manner as to be electrically connected to the circuit wires; and a front sheet attached to top of the main sheet.

Abstract: Provided is a soft box having a plurality of poles, an adapter ring having a plurality of holes into which the plurality of poles is correspondingly coupledly inserted, and a reflecting cloth adapted to connect the plurality of poles in such a manner as to reflect light therefrom, the soft box including: a zipper mounted on the reflecting cloth between the neighboring poles; and an auxiliary reflecting cloth disposed on the reflecting cloth adjacent to the inner side of the zipper along the longitudinal direction of the zipper in such a manner as to cover the inner surface of the zipper.
