    Abstract: A lens for use in a lighting arrangement, such as an LCD backlight, includes a light guiding region and a lens surface. The light guiding region is shaped to focus light from a light source toward a region of the lens located on its periphery. The lens surface has reflection regions for reflecting light from the light source back into the lens and transmission regions for transmitting light from the light source outside the lens. A characteristic of the transmissions regions, such as width, varies as a function of the location of the light source so as to create substantially uniform average light distribution for areas of the lens positioned at various distances with respect to the light source.

    Abstract: An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second deflected direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources from the side of the waveguide and hence defines the relative positions of system elements and ray paths. A directional backlight with small footprint and low thickness may be provided.
