| Title: |
Efficient and Uniformly Distributed Illumination from Multiple Source Luminaires |
| Abstract: |
Light projecting devices for integrating the light output from multiple
light emitting quasi point sources into unified predetermined light
patterns. The multiple light emitting quasi point sources (such as LEDs
[Light Emitting Diodes]) are generally stacked with a common optical
axis, each of the light emitting quasi point light sources further
surrounded by a ring collimator designed to collect and project a radial
beam of light away from the optical axis. In some embodiments, a series
of individual collimators surround each of the light emitting quasi point
sources and substitutions for the ring collimator forming an array of
beams projected away from the optical axis. Further, either of the
systems, whether incorporating a ring collimator or a series of
individual collimators, may use reflecting surfaces to intercept and
redirect the radiating collimated light into distribution patterns
ranging from focused beams to ambient broad light distribution.
