Abstract
A lens for distribution of light from a light emitter having an emitter axis. The lens comprising an inner surface and an output surface with faceted and smooth outer regions. At least one of the faceted outer regions is formed by a plurality of pairs of transverse outer regions extending in direction of a plane of bilateral symmetry of the lens. The inner surface defines an inner cavity about the emitter axis and has inner-surface stepwise discontinuities formed by a plurality of pairs of transverse inner regions with intersection regions therebetween. The lens may also have at least two secondary surface portions spaced apart and extending along two sides of the inner surface, the secondary surface portions being configured for total internal reflection (TIR) of light received from the inner surface.
