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 shield for a lighting fixture, the shield comprising:

a panel that is optically transparent; and

a screen attached to the panel, the screen having opaque segments, wherein the opaque segments have gaps therebetween, wherein the screen is screen printed onto the panel, wherein the opaque segments are distributed on the panel, and wherein the screen is made from a reflective material that reflects back a portion of a light that reaches the screen.

2. The shield of claim 1, wherein the panel is made from acrylic or glass.

3. The shield of claim 1, wherein a group of second opaque segments are distributed on a second broad side of the panel.

4. The shield of claim 1, wherein the reflective material is a white reflective material.

5. The shield of claim 1, wherein the screen allows light to pass through between the gaps.

6. A light fixture, comprising:

a housing having a top opening and a bottom opening;

a light source 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; and

a shield attached to the housing, wherein the shield is disposed above the light source, the shield comprising;

a panel that is optically transparent; and

a screen attached to the panel, the screen having opaque segments, wherein the opaque segments have gaps therebetween, wherein the screen is screen printed onto the panel, wherein the opaque segments are distributed on the panel, wherein the uplight includes a first portion of the light that passes through the gaps, and wherein the downlight includes a second portion of the light that is reflected down by the opaque segments.

7. The light fixture of claim 6, wherein the panel is made from acrylic or glass.

8. The light fixture of claim 6, wherein a group of second opaque segments are distributed on a second broad side of the panel.

9. The light fixture of claim 6, wherein the screen is made from a white or silver reflective material.

10. The light fixture of claim 6, wherein the pattern is designed to provide a desired light distribution above and below the housing.

11. The light fixture of claim 6, further comprising a lens below the light source, wherein the lens is positioned for the downlight to pass through the lens.

12. The light fixture of claim 6, wherein the shield is positioned on the housing above the light source.

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