Abstract
A compact and cost-efficient lamp assembly includes cold-cathode fluorescent lamps in a variety of edge-lit display sign applications, specifically, in edge-lit emergency lighting signs. The lamp assembly includes in one self-contained module a lower housing unit and an upper housing unit shaped to cover the lower housing unit. The lower housing unit is divided into a lower frame and an upper frame disposed on top of the lower frame. The upper frame has at least two inverters disposed within. The lower frame is a parabolic shaped reflector frame supporting at least two cathode lamps in line with the two inverters, each of which is connected to each lamp for providing high voltage to power up the lamps. Additionally, an edge-lit panel having a front and back side is disclosed. The back side includes a semi-transparent frosted surface with a white opaque lamination glued on the frosted surface. A legend is printed on the front side using a first white layer and a colored second layer of semi-transparent materials. When light passes through the first layer it is split so that part of the light is reflected back into the panel and the other part of the light illuminates the second colored layer.
Claims (14)
1. A display light sign assembly comprising:
a parabolic-shaped reflector frame having top and bottom surfaces, and side walls extending from at least a first end to a second end;
an upper frame disposed on the top surface of the reflector frame;
at least one cold-cathode fluorescent lamp disposed within said reflector frame wherein said reflector frame reorients radial beams from the lamp into parallel light beams; and at least one essentially semi-transparent elongated, protective panel attached to said reflector frame extending from said first end to said second end, wherein said parallel light beams are directed into the panel.
a parabolic-shaped reflector frame having top and bottom surfaces, and side walls extending from at least a first end to a second end;
an upper frame disposed on the top surface of the reflector frame;
at least one cold-cathode fluorescent lamp disposed within said reflector frame wherein said reflector frame reorients radial beams from the lamp into parallel light beams; and at least one essentially semi-transparent elongated, protective panel attached to said reflector frame extending from said first end to said second end, wherein said parallel light beams are directed into the panel.
2. The assembly of claim 1 wherein said frame includes built-in stoppers to guide the panel in proximity with the lamp.
3. The assembly of claim 1 further comprising:
panel guides secured to said panel to align the said frame to the panel.
panel guides secured to said panel to align the said frame to the panel.
4. The assembly of claim 1 further including an inverter connected to the lamp for providing low DC
voltage to power the lamp.
voltage to power the lamp.
5. The assembly of claim 1 wherein said parallel light beams are perpendicular to the panel edge.
6. The assembly of claim 1 wherein said protective panel is an edge-lit panel.
7. The assembly of claim 1 wherein said protective panel is generally rectangular in shape.
8. The assembly of claim 1 wherein said protective panel comprises a single essentially rectangular panel.
9. The assembly of claim 1 wherein said protective panel is plastic.
10. An edge-lit panel comprising:
a front side and a backside, said backside including a semi-transparent frosted surface;
a white opaque lamination glued on said frosted surface; and a legend printed on said front side using first and second layers of semi-transparent materials;
wherein said first layer is white and said second layer is colored such that light passing through said first layer is split in a manner that part of the light is reflected back into the panel and the other part of the light illuminates the second layer.
a front side and a backside, said backside including a semi-transparent frosted surface;
a white opaque lamination glued on said frosted surface; and a legend printed on said front side using first and second layers of semi-transparent materials;
wherein said first layer is white and said second layer is colored such that light passing through said first layer is split in a manner that part of the light is reflected back into the panel and the other part of the light illuminates the second layer.
11. The panel of claim 10 further comprising:
a contour engraved on the legend to accentuate the contrast between the legend and the backside.
a contour engraved on the legend to accentuate the contrast between the legend and the backside.
12. The panel of claim 10 wherein said reflected light is reflected on the backside of the panel.
13. The panel of claim 10 wherein said part of the refracted light passes through the first layer and illuminates the second layer.
14. The panel of claim 10 wherein said lamination is plastic.
