Abstract
An illumination device for simulating neon lighting comprising a plurality of spaced point light sources positioned adjacent a lateral light receiving surface of a substantially rod-like waveguide made of a material that preferentially scatters light entering the light receiving surface such that the light intensity pattern exiting a lateral light emitting surface of the waveguide has a substantially uniform light intensity pattern.
