Illuminated sign and light source for use with said sign
An illuminable sign ( 20 ) has a base ( 22 ); a trough ( 24 ) having a configuration C formed in the base ( 22 ); a light dispensing medium ( 26 ) having the configuration C fitted in the trough ( 24 ) and including a pair of light-entering ports ( 28, 30 ); a light generator ( 32 ) fixed in operative relation between the pair of light-entering ports ( 28, 30 ), the light generator ( 32 ) including at least one light source ( 34 ); and a cover ( 36 ) fitted to the base.
1. A light generator comprising:
a thermally conducting housing having a bottom surrounded by upstanding walls, said bottom extending in a first direction;
a projection adjacent one of said walls and extending orthogonal to said first direction;
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 and parallel to said bottom and fitted in said bottom;
a dielectric layer positioned between said housing and said electrically conductive member; and
two light sources, one each operatively positioned on each leg of said U-shaped portion.
2. The light generator of claim 1 wherein said light sources are light emitting diodes.
3. The light generator of claim 2 wherein said housing is provided with a plurality of heat-radiating fins.
4. The light generator of claim 3 wherein one of said walls is provided with a wire inlet.
5. The light generator of claim 1 wherein at least one of said walls includes a mounting flange.
6. The light generator of claim 5 wherein each of two, oppositely disposed walls includes a mounting flange.
