Abstract:
A non-glare luminaire includes a toroidal-shaped light engine having light emitting diodes (LEDs) disposed about the light engine in a radial pattern. The light engine has an axial direction that is at least substantially orthogonal to the surface of the light engine. An anti-glare ring is disposed proximate the light engine and includes reflectors arranged in a radial pattern. Each reflector is configured to reflect tangentially oriented light from at least one of the LEDs substantially along the axial direction. The luminaire also includes a toroidal integrated optic (TIO), which is made up of a total internal reflectance (TIR) lens that is coupled with a light guide. The TIO optic has a toroidal lens portion having a light entrance side that receives light from the LEDs and the reflectors. The optic collimates the light received from the LEDs and the reflectors and emit the light via a light exit side.
