Abstract
Abstract A furnishing or other like structure having an illuminated, decorative design formed on at least open surface thereof. The decorative design is created by a sheet or rod formed of a light transparent, fluorescent substance containing material, one edge of which extends through and is generally flush with the surface of the furnishing. This sheet or rod is illuminated along a lower portion thereof which extends below the surface of the furnishing. The lower portion of the rod or sheet, and the light source are shielded by a housing so that no light is visible, except along the illuminated edge on the surface of the furnishing. A fan or other cooling device may be provided for removing heat from the light source while still preventing the escape of light. Such sheets or rods may be provided either singly, or in a plurality to form the desired decorative design.

Claim 5
Dependent Claim
17 words
A structure as recited in claim 1 further comprising means for removing heat from said illuminating means.
Claim 6
Dependent Claim
23 words
A structure as recited in claim 2 wherein said element is comprised of a transparent acrylic which has been dyed a desired color.
Claim 7
Dependent Claim
23 words
A structure as recited in claim 2 wherein said element is comprised of a transparent polycarbonate which has been dyed a desired color.
Claim 8
Dependent Claim
22 words
A structure as recited in claim 1 further comprising means for varying the intensity of the light emitted by said illuminating means.
Claim 9
Dependent Claim
40 words
A structure as recited in claim 1 wherein said element is formed as a sheet, and wherein said element extends at least part way across one dimension of said structural member, whereby said edge comprises one edge of said sheet.
Claim 10
Dependent Claim
60 words
A structure as recited in claim 8 wherein said illuminating means comprises an elongated bulb which extends generally parallel to said upper surface and which is generally coextensive with the extent of said lower portion along said one dimension of said structural member, said bulb being in confronting spaced relation along its length with said lower portion of said element.
Claim 11
Dependent Claim
55 words
A structure as recited in claim 8 wherein said illumination means comprises a plurality of discrete, incandescent bulbs spaced from said lower portion and extending at spaced intervals along said lower portion of said element, said bulbs being generally coextensive with the extent of said lower portion along said one dimension of said structural member.
Claim 12
Dependent Claim
45 words
A structure as recited in claim 4 wherein said heat removing means comprises: vents disposed in said housing; means covering said vents for permitting air to pass therethrough, but not light; and a fan disposed in said housing for circulating air past said illuminating means.
Claim 13
Dependent Claim
