摘要:
Lightguides, devices incorporating lightguides, processes for making lightguides, and tools used to make lightguides are described. A lightguide includes light extractors arranged in a plurality of regions on a surface of the lightguide. The orientation of light extractors in each region is arranged to enhance uniformity and brightness across a surface of the lightguide and to provide enhanced defect hiding. The efficiency of the light extractors is controlled by the angle of a given light extractor face with respect to a light source illuminating the light guide.

Light assembly having reflector (17), a light source (22), an outer light cover (12) having a first color zone (15) and a second, different color or clear zone (16), and an inner lens (19) with a transflective surface. Embodiments of light assemblies described herein are useful, for example, as signs, backlights, displays, task lighting, luminaire, and vehicle (e.g., cars, trucks, airplanes, etc.) components. Vehicle comprising light assemblies include those where the light assembly is a vehicle tail light assembly.

Lightguide is disclosed. The lightguide includes a staircase shape optical construction that includes a plurality of light reflecting risers. At least two of the risers include non-parallel light reflecting portions.
摘要:
A lightguide (100) is disclosed. The lightguide includes a plurality of light extractors (120-123). Each light extractor is designed primarily to extract light that propagates within the lightguide and is incident on the light extractor from a first direction and reflect light that propagates within the lightguide and is incident on the light extractor from a second direction different than the first direction, toward another light extractor, where the other light extractor extracts the reflected light.
摘要:
A process comprises imagewise exposing at least a portion of a photoreactive composition to light sufficient to cause simultaneous absorption of at least two photons, thereby inducing at least one acid- or radical-initiated chemical reaction where the composition is exposed to the light, the imagewise exposing being carried out in a pattern that is effective to define at least the surface of a plurality of light extraction structures.

Semiconductor devices are described that include a semiconductor layer that comprises a perfluoroether acyl oligothiophene compound, preferably an α,ω-bis-perfluoroether acyl oligothiophene compound. Additionally, methods of making semiconductor devices are described that include depositing a semiconductor layer that contains a perfluoroether acyl oligothiophene compound, preferably an α,ω-bis(2-perfluoroether acyl oligothiophene compound.
