Abstract

A seat light and plaque holder including a seat light base having a downwardly angled mounting surface and an upwardly angled mounting surface with a first plurality of LEDs mounted on the downwardly angled mounting surface and a second plurality of LEDs is mounted on the upwardly angled mounting surface. A light cover is attached to the seat light base having a row marker positioned thereon to be backlit by the second plurality of LEDs and an end portion of a length selected to shield the downwardly angled first plurality of LEDs from view of persons walking up or down an aisleway while directing illumination towards an aisleway.

Claims

1. Light fixture apparatus comprising:

a seat light base having a downwardly angled mounting surface and an upwardly angled mounting surface;

an LED shroud containing a first circuit board mounting a first plurality of LEDs, the shroud being mounted on said downwardly angled mounting surface;

a second circuit board mounting a plurality of LEDs, the second circuit board being positioned on said upwardly angled mounting surface; and

a light cover mounted to said seat light base and having a marker positioned thereon to be backlit by said second plurality of LEDs and having an end portion of a length selected to shield said first plurality of LEDs from view of persons walking up or down an aisleway, while directing illumination towards said aisleway.

2. The light fixture apparatus of claim 1 wherein the first circuit board is positioned flush against parallel horizontal rims located on an interior surface of said shroud.

3. The light fixture apparatus of claim 2 wherein the front surface of each of said first plurality of LED'"'"'s lies flush with a front surface of said shroud.

4. The light fixture apparatus of claim 1 wherein said downwardly angled surface lies at an angle of 20 degrees to the vertical.

5. The light fixture apparatus of claim 1 wherein said seat light base has a flat back surface.

7. The light fixture apparatus of claim 1 wherein the first plurality of LED'"'"'s are mounted on a first circuit board which is positioned flush against parallel horizontal rims located on an interior surface of a shroud.

8. The light fixture apparatus of claim 2 wherein the front surface of each of said first plurality of LED'"'"'s lies flush with a front surface of said shroud.

9. The light fixture apparatus of claim 1 wherein said first circuit board is mounted on a downwardly angled surface lying at an angle of 20 degrees to the vertical.

10. The light fixture apparatus of claim 1 wherein said seat light base has a flat back surface.

6. Light fixture apparatus comprising:

a seat light base;

a first plurality of LEDs positioned to direct light downwardly;

a second plurality of LEDs positioned to direct light upwardly; and

a light cover mounted to said seat light base and having a marker positioned thereon to be backlit by said second plurality of LEDs and having an end portion of a length selected to limit the visibility of said first plurality of LEDs to persons walking up or down an aisleway or other path, while directing illumination generated by said first plurality of LED'"'"'s toward said aisleway or path.
