Abstract
Abstract Lighting structure is described for both illuminating display panels associated therewith and for providing illumination to the area surrounding the structure. A plurality of mercury vapor lamps are disposed above and rearwardly of a display panel whilst a reflector extends forwardly of said panel above said lamps whereby said panel is illuminated on its rear face by direct transmission of light from said lamps and on its front face by reflected light; the area surrounding the structure being illuminated by light reflected from said reflectors and light transmitted through said panel. Said area may also be illuminated by direct light transmitted through a translucent baffle located above said panel below said reflector, or said translucent baffle may be omitted altogether. Alternatively, direct illumination of said area may be prevented by means of a grating-like baffle extending forwardly of and above the or each display panel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
A lighting structure comprising a box-like assembly having at least one translucent panel with an interior rear face and an exterior front face, a reflector disposed above said assembly and projecting forwardly of said front face of the panel, means accommodating installation of a source of high intensity illumination above the top of said assembly and below said reflector for directly illuminating said rear face of the panel through the top of said assembly, said reflector being angularly oriented relative to said assembly and to said source of illumination to reflect light from said source towards said front face of the panel whereby said panel is illuminated on both said front and rear faces thereof.
Claim 2
Dependent Claim
115 words
A lighting structure comprising a box-like assembly having at least one translucent panel with an interior rear face and an exterior front face, a reflector disposed above said assembly and projecting forwardly of said front face of the panel, means accommodating installation of a source of high intensity illumination above the top of said assembly and below said reflector for directly illuminating said rear face of the panel through the top of said assembly, said reflector being angularly oriented relative to said assembly and to said source of illumination to reflect light from said source towards said front face of the panel whereby said panel is illuminated on both said front and rear faces thereof.
Claim 3
Dependent Claim
61 words
Lighting structure as claimed in claim 1 wherein said reflector is oriented relative to said panel to reflect light from said source outwardly and downwardly of sAid reflector away from said front face whereby an area of illumination is provided forward of said front face below said reflector illuminated by light transmitted through said panel and light reflected from said reflector.
Claim 4
Dependent Claim
57 words
Lighting structure as claimed in claim 2 wherein a baffle of translucent material is located above said panel permitting light to be transmitted therethrough from said source forwardly of said panel below said reflector, said area of illumination being provided by light reflected from said reflector and by light transmitted through said panel and through said baffle.
Claim 5
Dependent Claim
58 words
A lighting structure as claimed in claim 2 wherein a baffle is interposed between the top edge of the panel and the reflector preventing direct transmission of light from said source forwardly of said panel below said baffle, said area of illumination being provided only by light reflected from said reflector and by light transmitted through said panel.
Claim 6
Dependent Claim
56 words
A lighting structure as claimed in claim 3 wherein said reflector is of generally arcuate overall configuration extending forwardly of said panel and said baffle whereby light from said source is directed both towards and away from said panel through the space between the forwardmost part of said baffle and the forwardmost edge of the reflector.
Claim 7
Dependent Claim
38 words
A lighting structure as claimed in claim 1 wherein said reflector is of generally arcuate overall configuration extending forwardly of said panel and comprising a plurality of elongated facets each inclined at a different angle to said panel.
Claim 8
Dependent Claim
51 words
A lighting structure as claimed in claim 1 wherein said box-like assembly includes two said translucent panels arranged in back-to-back relation to one another, a said reflector being associated with each said panel and said source installation means being disposed symmetrically above and between said panels and their respective said reflectors.
Claim 9
Dependent Claim
26 words
A lighting structure as claimed in claim 1 wherein said box-like assembly comprises a single said translucent panel arranged in back-to-back relation with opaque backing means.
Claim 10
Dependent Claim
40 words
A lighting structure as claimed in claim 1 wherein said box-like assembly includes a single said translucent panel and a reflector located adjacent the base of said assembly directing light from said source onto said rear face of said panel.
