Abstract
A multi-region lighting system for flat illumination includes one or more light sources and an optic. The optic comprises a first region characterized by a first refractive-index feature and a second region characterized by a second refractive-index feature. The second region comprises a ridge structure. The first and second refractive-index features and the ridge structure are operative to produce a composite light distribution from the one or more light sources.
Claims20
A system for a light fixture comprising
- one or more light sources;
- and
- an optic, wherein:
- the optic comprises:
- a first region comprising a first feature, wherein the first feature is a first texture;
- and
- a second region comprising a second feature and a ridge structure in the second region, wherein:
- the second feature is a second texture;
- and
- the first texture is rougher than the second texture;
- and
- the first feature, the second feature, and the ridge structure are arranged to produce a composite light distribution from the one or more light sources.
9 more elements
A method comprising:
- generating light from one or more light sources;
- transmitting a first portion of light from the one or more light sources through a first region of an optic, wherein the first region is characterized by a first feature;
- and
- transmitting a second portion of light from the one or more light sources through a second region of the optic, wherein:
- the second region is characterized by a second feature and a ridge structure in the second region;
- and
- the first feature, the second feature, and the ridge structure are operative to produce a composite light distribution from the one or more light sources;
- the first feature is a first texture;
- the second feature is a second texture;
- and
- the first texture is rougher than the second texture.
8 more elements
A system comprising:
- one or more light sources;
- and
- an optic, wherein:
- the optic comprises:
- a first region comprising a first feature, wherein the first feature is a first texture;
- and
- a second region comprising:
- a second texture, wherein the second texture is finer than the first texture;
- and
- a second feature arranged to focus light;
- and
- the first feature and the second feature are arranged to produce a composite light distribution from the one or more light sources.
