Abstract
Abstract The device is adaptable for any panel of non-opaque material, whether it concerns advertisement, information panel, signboards, signposts or signalling posts or the like. The panel 1 is associated with at least one source of lighting 3 which faces one of the edges 2 of the panel. The panel carries an engraving 7 having a surface which reflects light and divides the incident beam into a series of pencils of light associated with various elements of the engraving.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A luminous device comprising in combination: at least one panel of non-opaque material having edges and faces and acting as a support for indicia conveying information; at least one source of lighting located behind and to the side of said indicia, said lighting source being adapted to project light in a direction parallel to said indicia; and a plurality of reflecting surfaces disposed directly behind said indicia in fixed relationship to the latter and in a location to intercept light from said source thereby dividing the beam of light from said source into a plurality of pencils of light which are reflected past said indicia.
Claim 2
Dependent Claim
105 words
A luminous device comprising in combination: at least one panel of non-opaque material having edges and faces and acting as a support for indicia conveying information; at least one source of lighting located behind and to the side of said indicia, said lighting source being adapted to project light in a direction parallel to said indicia; and a plurality of reflecting surfaces disposed directly behind said indicia in fixed relationship to the latter and in a location to intercept light from said source thereby dividing the beam of light from said source into a plurality of pencils of light which are reflected past said indicia.

A device as claimed in claim 1, wherein said reflecting surfaces are presented by engravings on said panel.
Claim 4
Dependent Claim
23 words
A device as claimed in claim 2, wherein said reflecting surfaces are presented by a plurality of inclined elements disposed in offset relationship.
Claim 5
Dependent Claim
