Abstract

Abstract A lighted display panel system including apparatus for distributing fluorescent light through a lens having a transparency thereon. The apparatus comprises an open-sided housing having a cavity therein for receiving a plurality of fluorescent bulbs in spaced proximity to an undulant reflector. The undulant reflector is located within the housing cavity and specifically designed to provide an optimal Kelvin rating as the fluorescent light from the bulbs is reflected therefrom and passes through the lens covering the housing cavity. The apparatus is incorporated into the lighted display system by a plurality of connection bars, connection rods, and an electrical buss bar. A method of assembling the lighted display panel system is also disclosed.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 185 words
A method of assembling an illuminated display panel system, comprising the steps of: inserting and attaching ends of at least two connection rods in an electrical bus bar, said bus bar having a plurality of electrical connectors and a plurality of orifices within which to receive said ends of said connection rods; sliding a hollow connection bar over said connection rods, said connection bar being adapted to be connected to a side of at least two illuminated display panels, each of said panels having electrical connectors on either end thereof and a cavity therein within which to receive a plurality of fluorescent bulbs and an undulant reflector, each of said panels including means for securing a lens thereto to thereby cover said cavity and means for securing said bulbs within said cavity between waves in said undulant reflector intermediate to said reflector and said lens; and attaching at least two of said panels to said connector bar in horizontal alignment parallel to said bus bar and with at least one of said electrical connectors on each of said panels electrically connected to said bus bar.
Claim 2
Independent Claim 185 words
A method of assembling an illuminated display panel system, comprising the steps of: inserting and attaching ends of at least two connection rods in an electrical bus bar, said bus bar having a plurality of electrical connectors and a plurality of orifices within which to receive said ends of said connection rods; sliding a hollow connection bar over said connection rods, said connection bar being adapted to be connected to a side of at least two illuminated display panels, each of said panels having electrical connectors on either end thereof and a cavity therein within which to receive a plurality of fluorescent bulbs and an undulant reflector, each of said panels including means for securing a lens thereto to thereby cover said cavity and means for securing said bulbs within said cavity between waves in said undulant reflector intermediate to said reflector and said lens; and attaching at least two of said panels to said connector bar in horizontal alignment parallel to said bus bar and with at least one of said electrical connectors on each of said panels electrically connected to said bus bar.
Claim 3
Independent Claim 204 words
A method of assembling an illuminated display panel system, comprising the steps of: inserting and attaching ends of at least two connection rods in an electrical bus bar, said bus bar having a plurality of electrical connectors and a plurality of orifices within which to receive said ends of said connection rods; sliding a hollow connection bar over each of said connection rods, said connection bar being adapted to be connected to a side of at least two illuminated display panels, each of said panels having a cavity therein within which to receive a plurality of fluorescent bulbs and an undulant reflector, each of said panels including means for securing a lens thereto to thereby cover said cavity and means for securing said bulbs within said cavity between waves in said undulant reflector intermediate to said reflector and said lens; attaching at least two of said panels to at least one of said connection bars in horizontal alignment parallel to said bus bar and electrically connected to said bus bar; and attaching at least two additional panels to said connection bar in horizontal alignment parallel to said buss bar, said additional panels being in vertical alignment with and electrically connected to the other panels.
Claim 4
Independent Claim 204 words
A method of assembling an illuminated display panel system, comprising the steps of: inserting and attaching ends of at least two connection rods in an electrical bus bar, said bus bar having a plurality of electrical connectors and a plurality of orifices within which to receive said ends of said connection rods; sliding a hollow connection bar over each of said connection rods, said connection bar being adapted to be connected to a side of at least two illuminated display panels, each of said panels having a cavity therein within which to receive a plurality of fluorescent bulbs and an undulant reflector, each of said panels including means for securing a lens thereto to thereby cover said cavity and means for securing said bulbs within said cavity between waves in said undulant reflector intermediate to said reflector and said lens; attaching at least two of said panels to at least one of said connection bars in horizontal alignment parallel to said bus bar and electrically connected to said bus bar; and attaching at least two additional panels to said connection bar in horizontal alignment parallel to said buss bar, said additional panels being in vertical alignment with and electrically connected to the other panels.
