Abstract
An illumination device for simulating neon lighting comprises a rod-like member having a predetermined length and a curved light emitting surface, an elongated light source extending substantially along the predetermined length of the rod-like member at a fixed distance from the light emitting surface, and a housing for said elongated light source. The housing includes opposing and substantially parallel side walls with internally light reflecting surfaces, such that the housing serves to collect and direct light emitted by said light source into the rod-like member, with such light then passing through and being scattered by the rod-like member so as to exit the curved light emitting surface in a substantially uniform light intensity pattern.
