Abstract

A shield for a lighting fixture includes a panel that is optically transparent and a screen attached to the panel. The screen has opaque segments, where the opaque segments have gaps therebetween. The screen is screen printed onto the panel. The opaque segments are distributed on the panel in a pattern.

Claims

1. A light fixture, comprising:

a housing;

a light source disposed within the housing;

a panel attached to the housing, wherein the panel is optically transparent;

a screen attached to the panel, wherein the screen includes one or more sections that are at least partially optically opaque and wherein the screen is screen printed onto the panel; and

a lens positioned below the light source and spaced from the light source and the panel, wherein the panel is positioned inside the housing below the light source and above the lens.

2. The light fixture of claim 1, wherein the panel is made from acrylic.

3. The light fixture of claim 1, wherein the panel is made from glass.

4. The light fixture of claim 1, wherein the screen is made from a reflective material.

5. The light fixture of claim 1, wherein the one or more sections are fully optically opaque.

6. The light fixture of claim 1, wherein the light source includes a light emitting panel.

7. The light fixture of claim 1, wherein the light source includes a fluorescent light source.

8. The light fixture of claim 1, wherein the light source includes multiple fluorescent light sources.

9. The light fixture of claim 1, wherein the panel is positioned on a frame of the housing.

10. The light fixture of claim 1, wherein the screen allows light to pass through between the one or more sections.

11. The light fixture of claim 1, wherein the housing comprises a top opening and a bottom opening and wherein the light source is disposed within the housing and configured to emit a light that includes an uplight that exits the housing through the top opening and a downlight that exits the housing through the bottom opening.

12. The light fixture of claim 1, wherein the lens is positioned at an opening of the housing and wherein the panel is positioned on a frame of the housing distal from the opening.

13. A light fixture, comprising:

a housing;

a light source disposed within the housing;

a panel attached to the housing, wherein the panel is optically transparent and wherein the panel is disposed below the light source; and

a screen attached to the panel, wherein the screen includes one or more sections that are at least partially optically opaque, wherein the screen is screen printed onto the panel, wherein the housing comprises a top opening and a bottom opening, and wherein the light source is disposed within the housing and is configured to emit a light that includes an uplight that exits the housing through the top opening and a downlight that exits the housing through the bottom opening.

14. The light fixture of claim 13, wherein the panel is made from acrylic.

15. The light fixture of claim 13, wherein the screen is made from a reflective material.

16. The light fixture of claim 13, wherein the one or more sections are fully optically opaque.

17. The light fixture of claim 13, wherein the light source includes a light emitting panel.

18. The light fixture of claim 13, wherein the light source includes a fluorescent light source.

19. The light fixture of claim 13, wherein the panel is positioned on a frame of the housing.
