Abstract: Lighting systems and devices include a light-transmissive tube and a light source assembly. The light-transmissive tube defines a cavity that extends along a longitudinal axis, at least a portion of the tube having an inner structured surface facing the cavity, and an outer structured surface facing away from the cavity. The light source assembly is disposed to inject light into the cavity, and includes one or more discrete light sources such as LED sources. The inner and outer structured surfaces of the tube are configured to direct a first portion of the injected light out of the tube through the outer structured surface and to direct a second portion of the injected light back into the cavity, such that a virtual filament, or pattern of virtual filaments, appears in the tube.

Abstract: A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

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.
