Patent number: 9678410Abstract: Diffusing light illuminating a light target or subject of a film or video production including placing a diffusion panel between a light source and a light target, energizing said light source so as to direct light therefrom through the diffusion panel, and electrically adjusting the transparency of the diffusion panel by changing an electric potential applied to electrodes of the diffusion panel. The electrically adjustable diffusion panel eliminates the need for manually changing diffusion papers or other filters and provides a continuous range of selectable levels of transparency/diffusion.Type: GrantFiled: July 6, 2015Date of Patent: June 13, 2017Assignee: Zylight LLCInventors: James H. Collias, Charles H. Collias, Nicholas J. Foster, Jeffrey M. Hamel

Patent number: 9605813Abstract: A Fresnel lighting instrument for use in film and video production, having a LED light engine mounted to a heat sink defining a first plane, a dual basket type focusing assembly adapted to longitudinally extend or retract a Fresnel lens away from and back to the first plane substantially without rotation along the longitudinal range of extension, to provide a fanless, cool operating, highly compact and lightweight Fresnel light suitable for studio or field use. The dual basket type design allows for transporting three Fresnel units in a standard milk crate since the unit collapses down whereas existing Fresnel lights all use a constant volume can-shaped housing within which the light source is repositioned.Type: GrantFiled: April 18, 2014Date of Patent: March 28, 2017Assignee: Zylight LLCInventor: James H Collias
