Abstract
An illumination device having an optical waveguide stage to which is optically coupled a light-projecting stage. The illumination device accepts light from a small isotropic light source such as a light emitting diode or a bulb coupled to the optical waveguide stage. The illumination device spreads the light over a wide area while also collimating it to form a beam. Alternatively, the light beam can also be shaped in a variety of ways. The light-projecting stage and the optical waveguide stage are made of thin slabs of optically transmissive material.
