Abstract
A light guide for a luminaire is provided. The light guide includes: an elongated base having a light emitting surface at a distal end, and opposing major faces; and a plurality of collimators projecting from the base, wherein each collimator has a light receiving surface at a proximal end. The plurality of collimators are arranged with spaces therebetween along the base. The light emitting surface has notches having a minimum width corresponding to the space between the collimators and a maximum width corresponding to a space between the light receiving surfaces. Substantially all light received at the light receiving surfaces internally reflects through the collimators and the base and emits from the light emitting surface, and the notches are configured to direct light emitted from the light emitting surface at a lower angle than if the notches were not present.
