| Title: |
Luminaires Using Multiple Quasi-Point Sources for Unified Radially Distributed Illumination |
| Abstract: |
A luminaire for providing broad uniform surface illumination and sharp
cutoff which has at least one quasi point light source, such as an LED,
located on an optical axis. There is at least one collimating ring lens
which, at least partially surrounds the quasi point light source. The
collimating ring projects a radial collimated beam and there is at least
one reflective ring, at least partially surrounding the collimating ring
lens. The reflecting ring reflects and redirects the collimated radial
beam as a canted radial beam through the optical axis. In another
embodiment at least one off axis collimating ring lens at least partially
surrounds at least one quasi point light source, and projects a canted
radial beam away from the optical axis. There is at least one ring
reflector which at least partially surrounds the optical axis and is
positioned to reflect the canted radial beam toward and through the
optical axis. In a further embodiment, at least one linearly collecting
reflector at least partially surrounds the quasi point light source and
the reflector projects a linear beam onto a substantially conical
reflector which redirects the linear beam into a radially directed beam.
