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.
