Abstract: Extended area lighting devices, which are useful e.g. as luminaires, include a light guide and diffractive surface features on a major surface of the light guide. The diffractive surface features are tailored to extract guided-mode light from the light guide. The light guides can be combined with other components and features such as light source(s) to inject guided-mode light into the light guide, light source(s) to project light through the light guide as non-guided-mode light, a framework of interconnected support members (attached to multiple such light guides), and/or a patterned low index subsurface layer that selectively blocks some guided mode light from reaching the diffractive surface features, to provide unique and useful lighting devices. Related optical devices, and optical films having diffractive features that can be used to construct such devices and light guides, are also disclosed.

Abstract: A structured optical surface and an optical imaging system including the structured optical surface is described. The structured optical surface includes a plurality of structures formed by an intersection of at least first and second Fresnel patterns, such that when the structured optical surface is incorporated in an optical imaging system comprising a pixelated display surface with at least one pixel comprising at least two sub-pixels spaced apart by a gap, the structured optical surface images the at least two sub-pixels onto an image surface as at least two corresponding imaged sub-pixels spaced apart by a corresponding imaged gap, and the structured optical surface diffracts light so that the diffracted light at least partially fills the imaged gap without substantially overlapping any of the at least two imaged sub-pixels.
