Patent number: 10845532Abstract: A light shaping article includes a solid optic having a cross-sectional profile including an input interface; a convex output surface opposite the input interface; a concave first side surface extending between the input interface and the convex output surface; and a second side surface opposite the concave first side surface extending from between input interface to the convex output surface. The concave first side surface and the convex output surface are configured such that, when the solid optic receives input light having an input angular range in a plane of the cross-sectional profile, the solid optic guides the light to and emits the light from the output surface in an output angular range in the plane. A prevalent propagation direction of output light in the output angular range is tilted toward the second side surface relative to a prevalent propagation direction of input light in the input angular range.Type: GrantFiled: April 16, 2019Date of Patent: November 24, 2020Assignee: Quarkstar LLCInventors: Ingo Speier, Victor E.

Patent number: 10707435Abstract: Light-emitting elements such as LEDs are associated with light-converting material such as phosphor and/or other material. A donor substrate comprising the light-converting and/or other material is suitably placed relative to a target substrate associated with the light-emitting elements. A laser or other energy source is then used to transfer the light-converting and/or other material in a pattern via writing or masking from the donor substrate to the target substrate in accordance with the pattern. Addressability and targetability of the transfer process facilitates precise patterning of the target substrate.Type: GrantFiled: May 15, 2015Date of Patent: July 7, 2020Assignee: Quarkstar LLCInventors: Ingo Speier, Robert C.
