Abstract

Lighting apparatus includes an elongated body of optical material forming an optical channel (5) having high refractive index, and is adapted to receive luminous flux (13) at one or both ends of the body for lateral emission of luminous flux at substantially uniform surface intensity per unit length of the channel. Discrete diffusive targets (15, 16, 17, 18) are disposed at aperiodically-spaced locations on a smooth interface of the channel with surrounding air to control the uniformity of diffused light per unit length laterally emitted from the channel. A computer-implemented calculation determines optimum orientations of discrete targets on the interfacing surface for substantially uniform intensity of laterally-emitted luminous flux per unit length from the optical channel.
