1. An illuminated sign comprising:
- a housing having a plurality of internal surfaces, wherein at least one of said internal surfaces is a translucent surface and at least one of the remaining internal surfaces is a diffusely-reflective surface;
a transparent substrate disposed within said housing; and
at least one light emitting diode (LED) having an illumination field, said LED being positioned such that said illumination field is directed towards said diffusely-reflective surface, and said LED is interconnected with said transparent substrate.

Abstract
An illuminated sign having an LED as a light source as claimed. A housing has a plurality of internal surfaces wherein at least one of the internal surfaces is a translucent surface. A reflective layer covers each of said internal surfaces except the translucent surface. At least one LED is positioned between the internal surfaces such that the illumination field of the LED is in a direction substantially opposite that of the translucent surface.

22. A method of illuminating a sign, the method comprising the acts of:
-
providing a housing having internal surfaces, wherein a first surface of the housing is translucent and at least one of said internal surfaces other than said translucent surface is diffusely reflective;
providing a transparent substrate;
interconnecting at least one LED to said transparent substrate, said at least one LED having an illumination field when active; and
placing said transparent substrate within said housing such that said illumination field is substantially in the direction of said diffusely reflective surface, said placing act including conforming the transparent substrate to accommodate the housing. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 35, 37)
