Patent Number: 9605813 
Title: LED Fresnel Lighting Instrument 
Abstract:

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.
