First Claim
Patent Images
1. An illumination system, comprising:
- a single aperture configured to admit light from a light source and output light;
a light envelope receiving light admitted through the single aperture; and
wavelength conversion material disposed within the light envelope, for converting light received by the light envelop from a first wavelength range to a second wavelength range.

Abstract
A wavelength conversion material with an omni-directional reflector is utilized to enhance the optical efficiency of an illumination system with a single aperture for inputting and outputting light beams. Light guides with restricted output apertures, micro-element plates and optical elements are utilized to enhance the brightness of delivered light through light recycling. Furthermore, micro-element plates may be used to provide control over the spatial distribution of light in terms of intensity and angle. Efficient and compact illumination systems that utilize single light source with deflectors are also disclosed.
