摘要： Extended area lighting devices include a light guide and diffractive surface features on a major surface thereof. The diffractive surface features include diffractive features of different pitches in non-overlapping regions of the major surface tailored to extract guided-mode light of different colors from the light guide in different directions. The diffractive features extract light such that an ordinary user observes substantially different colors in different regions of the light guide, providing a colorful appearance. Notwithstanding this, the diffractive features also extract light such that the lighting device illuminates a reference surface, disposed at an intermediate distance from the light guide, with illumination light that is substantially uniform in color and substantially white. Optical films having diffractive features that can be used to construct such devices and light guides are also disclosed. The concept can also be extended to embodiments in which the uniform color illumination light is not substantially white.

摘要： Extended area lighting devices include a light guide and diffractive surface features on a major surface of the light guide. The diffractive surface features provide low distortion for viewing objects through the light guide. Light from discrete light source(s) is injected into the light guide, and the diffractive surface features interact with the injected light to couple guided-mode light out of the light guide. The out-coupled light produces one or more bands whose apparent shape changes with viewing position. The bands may be bright bands that correspond to the discrete light sources, or dark bands associated with an optional non-uniform reflective structure extending along a side surface of the light guide. Multiple bands may form a pattern that changes with viewing position, the pattern of bands having a 3-dimensional appearance for at least some viewing positions. The lighting devices can be used as luminaires for general lighting or decorative lighting.
