摘要： Lighting systems include a light-transmissive tube and a light source assembly disposed to inject light into a cavity defined by the tube. The cavity extends along a longitudinal axis. At least a portion of the tube includes an inner structured surface facing the cavity, and an outer structured surface facing away from the cavity. The inner structured surface is configured to direct a first portion of the injected light towards the outer structured surface, and a second portion of the injected light back into the cavity. The inner structured surface includes elongated first features and the outer structured surface includes elongated second features. At least one of the elongated first features and the elongated second features are oriented obliquely relative to the longitudinal axis such that they form respective helixes along the tube.

摘要： Optical systems are disclosed. More particularly, optical systems including an asymmetric turning film (110) with at least a first (120) and second light source (130) are disclosed. Selection of geometries for the asymmetric turning film can enable different output viewing angles depending on the selective illumination of the first light source, the second light source, or both. The optical systems disclosed may be suitable in both luminaires and displays.

摘要： This application describes a back- lit transmissive display including a transmissive display ( 620 ) and a variable index light extraction layer ( 640 ) optically coupled to a lightguide ( 630 ). The variable index light extraction layer has first regions ( 140 ) of nanovoided polymeric material and second regions ( 130 ) of the nanovoided polymeric material and an additional material. The first and second regions are disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. The transmissive display may be a transmissive display panel or a polymeric film such as a graphic.

The assembly further includes a structured surface layer positioned between the plurality of light sources and the input surface. The structured surface layer includes a substrate and a plurality of structures on a first surface of the substrate facing the plurality of light sources. The assembly further includes a plurality of extraction features operable to direct light from the light guide through an output surface of the light guide.
