    Abstract: The subject invention comprises a lighting assembly that utilizes the combination of a wave-guide and a Fresnel prism to advantageously direct light emitted from a light source. An exemplary embodiment of the subject invention comprises a light source, a wedge shaped wave-guide and a Fresnel prism. Another exemplary embodiment of the subject invention comprises a light source, a Fresnel wave-guide and a Fresnel prism. In either embodiment, light emitted from the light source passes either from the light source into the wave-guide or through a light pipe into the wave-guide. The wave-guide will select the exiting angle of the light rays so that the light will emit from the wave-guide at approximately the same angle and pass into the Fresnel prism. The Fresnel prism will cause the light to be emitted from the lighting assembly at nearly a normal angle.
