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.
