Abstract
An illumination device for simulating neon lighting comprising a plurality of space 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.

1-40. (canceled)
An illumination device, comprising:
- 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 said rod-like member at a fixed distance from said light emitting surface;
- and
- a housing for said elongated light source, said housing including opposing and substantially parallel side walls with internally light reflecting surfaces, such that said housing serves to collect and direct light emitted by said light source into said rod-like member, with such light then passing through and being scattered by said rod-like member so as to exit the curved light emitting surface in a substantially uniform light intensity pattern.

An illumination device, comprising:
- an essentially solid, leaky waveguide rod having a predetermined length and a curved light emitting surface;
- an elongated light source extending substantially along the predetermined length of said waveguide rod at a fixed distance from said light emitting surface;
- and
- opposing and substantially parallel side walls positioned on either side of said light source, each having internally light reflecting surfaces that serve to collect and direct light emitted by said light source into said waveguide rod, with such light then passing through and being scattered by said waveguide rod so as to exit the curved light emitting surface in a substantially uniform light intensity pattern.
