Abstract
An illumination device for the simulation of neon lighting comprises a leaky waveguide rod having a light-emitting lateral surface and a first set of one or more point light sources positioned adjacent one or both ends of the waveguide rod, the attenuation of light along the length of the waveguide rod being controlled such that light emitted from the lateral surface of the waveguide rod has essentially the same intensity over the length of the waveguide rod.
