Abstract: A lens for distribution of light predominantly toward a preferential side from a light emitter having an emitter axis. The lens includes an outer surface, a reflecting inner surface and a reflecting back surface. The reflecting inner surface is positioned and configured for total internal reflection (TIR) of received light toward the lens outer surface. The reflecting back surface is positioned and configured for total internal reflection (TIR) of received light toward the preferential side.

Abstract: A lens for distribution of light predominantly toward a preferential side from a light emitter having an emitter axis and defining an emitter plane. The lens has an emitter-adjacent base end forming an emitter-receiving opening to an emitter-surrounding cavity defined by an inner surface which includes a front sector centered on the preferential side and a back sector centered on the non-preferential side radially opposite the preferential side. The front and back sectors differ in their respective configurations for refracting light from the emitter. The lens further includes an primary back surface positioned to receive light from at least a portion of the inner-surface back sector and configured for total internal reflection (TIR) thereof. The inner-surface back sector and the primary back surface extend along substantially elliptical cross-sections in planes substantially parallel to the emitter plane. The emitter-adjacent base end forms a back opening to a back cavity substantially centered on the non-preferential side and partially bounded by the primary back surface.

Abstract: A lighting apparatus including an LED light emitter having an axis. The apparatus comprising a first lens over the emitter a second lens spaced over the first lens. The first lens is configured to direct LED-emitted light primarily toward a preferential radial side with respect to the emitter axis. The first lens may be an asymmetric primary lens. The first lens may have a centerline which is offset from the emitter axis toward the preferential radial side. Alternatively or in addition, the first lens may have an outer surface configured to direct LED-emitted light primarily toward the preferential radial side. The second lens may be asymmetric and be configured to further direct the light primarily toward the preferential radial side. The secondary lens may include inner and outer surfaces each shaped to direct received light primarily toward the preferential side.
