Claims (15)

1. An illuminated sign comprising:

a base;

a trough having a configuration formed in said base;

a light dispensing medium having said configuration fitted in said trough and including a pair of light-entering ports, said light dispensing medium comprising an acrylic rod having an upper surface and a bottom surface, said bottom surface being in contact with said trough and having lens forming striations formed therein;

a light generator fixed in operative relation between said pair of light-entering ports, said light generator including at least one light source; and

a cover fitted to said base.

2. The illuminated sign of claim 1 wherein said trough is semi-circular in cross-section and said light dispensing medium is circular in cross-section.

3. The illuminated sign of claim 2 wherein said trough is surrounded on both sides by a cover-receiving channel.

4. The illuminated sign of claim 1 wherein said base has an opening therein to receive said light generator.

5. The illuminated sign of claim 4 wherein said light generator comprises a thermally conducting housing having a bottom surrounded by upstanding walls;

a projection adjacent one of said walls;

an electrically conductive member fitted with said housing, said electrically conductive member having a U-shaped portion fitted over said projection and a planar section extending normal to said U-shaped section fitted in said bottom;

a dielectric layer positioned between said electrically conductive member and said housing; and

two light sources, one each operatively positioned on each leg of said U-shaped portion; and said projection penetrates said opening.
