Patent number: 12222080Abstract: Aspects of the disclosure include lighting assemblies and methods of using the same that leverage auto-shading laminates to support a common cavity for mixed lighting applications. An exemplary vehicle includes a lighting assembly having a common cavity. The common cavity includes an outer lens coated with an auto-shading film, a primary light source positioned behind the outer lens, a secondary light source positioned on an edge of the outer lens, and a wire embedded in the auto-shading film. The auto-shading film includes discrete substructures which vary in alignment in response to an electric field, thereby varying a transmittance through the outer lens. A controller is electrically coupled to the wire. The controller is configured to direct a switching voltage to a switch to change a state of the switch, thereby causing the wire to deliver the electric field to the discrete substructures to change the transmittance of the auto-shading film.Type: GrantFiled: November 8, 2023Date of Patent: February 11, 2025Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Jonglee Park, Thomas S.
