Abstract
Official abstract text for this publication.
This disclosure provides systems, methods, and apparatus for providing illumination for lighting systems. One or more light emitters can be disposed about a longitudinal axis, such as in an at least partial polygonal shape, so that the light sources emit light radially outwardly away from the longitudinal axis. A collimating reflector can be disposed radially outward of the one or more light emitters and can be configured to at least partially collimate the light and to substantially preserve etendue of the light emitted from the light emitters. The one or more light emitters can substantially fill an input aperture of the collimating reflector in a direction of the longitudinal axis. The light can be coupled into a light guide, which can be configured to distribute the light to a target lighting area.
First claim
Opening claim text (preview).
What is claimed is: 1. A light source comprising: one or more light emitters having one or more light emitting surfaces disposed about a longitudinal axis and oriented to output light radially outwardly away from the longitudinal axis; and a collimating reflector disposed radially outward of the one or more light emitters, all or part of the collimating reflector configured to at least partially collimate light output by the one or more light emitters and to substantially preser…
