DETAILED DESCRIPTION OF THE INVENTION
With reference to the drawings, an illuminated display device in accordance with the invention, is designated generally by the reference numeral 10. The illuminated display device comprises, broadly, a rear mounting structure 12 having an electrical light source in the form of a number of light-emitting diodes 14, mounted thereto, a translucent front panel 16 and an edging structure 18 disposed between the rear mounting structure and the front panel 16.
The front panel 16 comprises a 5mm thick panel 20 of bright white high density extruded polystyrene foam material. The front panel 20 has a generally rectangular shape with rounded edges and has sign indicia 22 "ABC" marked thereon. More specifically, the sign indicia 22 comprise an ink which is applied to an outer face of the panel 20 in a digital printing process. The rear mounting structure 12 includes a rear panel 24 of bright white high density extruded polystyrene foam material which has a shape and dimensions identical to the shape and dimensions of the front panel 20. The light-emitting diodes 14 are mounted in a grid pattern to an inner face of the rear panel 24. The diodes are connectable to an electrical power source.
The edging structure comprises a continuous strip 26 of extruded polystyrene foam formed into an annular shape corresponding to the profiles of the front and rear panels 20 and 24. More specifically, the edging structure is shaped so as to close off outer side edges of the front and rear panels and for spacing the front and rear panels from one another. More specifically, the edging strip is bonded to the front and rear panels by means of a suitable adhesive.
The applicant believes that the illuminated display device provides a low cost and easy to manufacture, yet effective illuminated sign wherein the material properties and thickness of the high density extruded polystyrene foam render the front panel sufficiently translucent to permit light emitted by the light-emitting diodes to pass therethrough thereby illuminating the sign indicia.
