Abstract
Abstract A decorative sign which simulates the appearance of neon lighting and a method for making the same is described in which a polymer fluorescent gel is cast upon and bonded to a plane in a "neon" shape and is activated by exposure to an activating lamp.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A lighting fixture simulating the appearance of a neon lamp comprising: a base panel to which there is applied a three dimensional mass of a fluorescent pigmented cast polymeric material in a predetermined pattern, said mass of pigmented polymeric material simulating a neon glow when activated by an activating lamp, said base panel and said mass of cast polymeric material being further intrinsically adhesively bonded at the interface of the panel and the mass of cast polymeric material, said interface being an abraded area on the base panel corresponding substantially to the predetermined pattern of the mass, and an activating lamp located in a proximate relationship to said panel, whereby the radiation from said lamp is directed to the pattern of the mass of pigmented polymeric material to produce a simulated neon glow.
Claim 2
Dependent Claim
133 words
A lighting fixture simulating the appearance of a neon lamp comprising: a base panel to which there is applied a three dimensional mass of a fluorescent pigmented cast polymeric material in a predetermined pattern, said mass of pigmented polymeric material simulating a neon glow when activated by an activating lamp, said base panel and said mass of cast polymeric material being further intrinsically adhesively bonded at the interface of the panel and the mass of cast polymeric material, said interface being an abraded area on the base panel corresponding substantially to the predetermined pattern of the mass, and an activating lamp located in a proximate relationship to said panel, whereby the radiation from said lamp is directed to the pattern of the mass of pigmented polymeric material to produce a simulated neon glow.
Claim 3
Dependent Claim
14 words
The fixture of claim 1 in which the activating lamp is a fluorescent lamp.
Claim 4
Dependent Claim
15 words
The fixture of claim 1 in which the base panel is transparent to ultraviolet radiation.
Claim 5
Dependent Claim
27 words
The fixture of claim 1 in which the abraded area of the interface between the base panel and the mass is a frosted area produced by sandblasting.
Claim 6
Dependent Claim
17 words
The fixture of claim 1 in which the three dimensional mass is formed from a polyester gel.
Claim 7
Dependent Claim
26 words
The fixture of claim 1, claim 4 or claim 5 in which the mass is in a linear form simulating the shape of a neon tube.
Claim 8
Dependent Claim
21 words
An assembly of the fixture of claim 1, claim 2, claim 3, claim 4, or claim 5 mounted in a box.
Claim 9
Dependent Claim
47 words
The assembly of claim 7 in which the activating lamp is included within the box and the mass is applied to an inner facing surface of the base panel and faces the lamp so that the outer facing surface of the base panel presents a flat surface.
