Publication number: 20220260234Abstract: A lighting device, such as a softbox 1 used for illumination in film locations, comprises a self-supporting funnel-shaped reflector 3 having a proximal edge 5 and a distal edge 7. A circumferential length of the funnel-shaped reflector at the proximal edge 5 is smaller than a circumferential length of the funnel-shaped reflector at the distal edge 7. The funnel-shaped reflector 3 is formed of a wall material 19 and the wall material is a thermoplastic material. The funnel-shaped reflector 3 includes plural corner lines 17 extending between the proximal edge 5 and distal edge 7, and wherein the corner lines 17 are formed by thermoplastic deformation of the wall material 19.Type: ApplicationFiled: February 14, 2022Publication date: August 18, 2022Inventor: Stefan Karle

Patent number: 11215903Abstract: Soft box mount, including a receiver block for receiving an expander strut of a soft box. The receiver block includes, in this order, an inward part, a transverse pivot axis, and an outward part, the outward part of the receiver block being configured to receive a proximal end of the expander strut; and a bar block which is configured to be movable between a first, non-use position, in which the inward part of the receiver block may intrude into a recessed part of the bar block, and a second, use position, in which a non-recessed part of the bar block urges, from a light source side, the inward part of the receiver block to assume a position radially inward of the pivot axis of the receiver block, thereby urging the outward part of the receiver block to assume a position radially outward of the pivot axis of the receiver block.Type: GrantFiled: November 6, 2020Date of Patent: January 4, 2022Inventor: Stefan Karle

Patent number: 8014654Abstract: A softbox for a spotlight includes a device for mounting the softbox to the spotlight such that in operation, the spotlight shines through the softbox. For limiting the emerging angle of the light shining through the softbox, a light control grid is mounted at the light emitting aperture of the softbox. For mounting the light control grid to the light emitting aperture of the softbox, a frame surrounds the light emitting aperture of the softbox. The control grid for being mounted to the softbox is manufactured by fixing adjacent strips of a light absorbing material to one another.Type: GrantFiled: September 11, 2009Date of Patent: September 6, 2011Inventor: Stefan Karle
