Lighting fixture with direct and indirect lighting
A lighting fixture and method of providing lighting is provided herein that utilizes both direct and indirect light sources. The direct and indirect light sources can be provided in arrays of light emitting diodes (LEDs) oriented along desired axes. In some versions, the light fixtures described herein include a direct lighting array having one or more LEDs oriented to project light downwardly and an indirect lighting array having a plurality of LEDs oriented to project light in a transverse direction. Further, the light fixtures can include an indirect lighting member configured to be illuminated by the plurality of LEDs of the indirect lighting array. Additionally, or alternatively, the light fixtures described herein can include one or more controllers that are configured to independently operate the direct and indirect lighting arrays. Moreover, the indirect lighting array can be configured to emit light in a plurality of colors to visually convey information.
1. A light fixture comprising:
a housing;
a direct lighting array coupled to the housing and comprising one or more light emitting diodes oriented to project light along a downward axis;
an indirect lighting array coupled to the housing and comprising a plurality of light emitting diodes oriented to project light along axes extending transverse to the downward axis; and
an indirect lighting member mounted to the housing to be laterally outwardly from and within a path of illumination of the plurality of light emitting diodes of the indirect lighting array, such that energizing the plurality of light emitting diodes of the indirect lighting array illuminates the indirect lighting member; wherein the indirect lighting member comprises a shroud coupled to the housing above the indirect lighting array, the shroud having an outer wall extending outwardly from the housing to intersect the path of illumination of the plurality of light emitting diodes of the indirect lighting array, and a bottom wall coupled to the housing to be laterally outwardly from and within the path of illumination of the plurality of light emitting diodes of the indirect lighting array, the outer wall of the shroud extending over at least a portion of the bottom wall; and
wherein the bottom wall is transparent or translucent, such that light emitted from the indirectly lighting array or transient light can pass therethrough to illuminate the outer wall of the shroud.
2. The light fixture of claim 1 , wherein the outer wall of the shroud comprises a convex configuration.
3. The light fixture of claim 1 , wherein the outer wall of the shroud comprises a concave configuration.
4. The light fixture of claim 1 , wherein the outer wall of the shroud comprises an angled portion having a linear cross-section in a vertical plane.
5. The light fixture of claim 4 , wherein a distal end of the outer wall of the shroud includes an upper surface and a lower surface angled relative to one another giving the distal end an outwardly pointed configuration.
6. The light fixture of claim 1 , wherein the outer wall of the shroud has a textured configuration such that the shroud is configured to diffuse light.
7. The light fixture of claim 1 , wherein a distal end of the outer wall of the shroud is disposed outwardly of an outer edge of the bottom wall.
8. The light fixture of claim 1 , wherein the shroud further comprises an interior wall, the outer wall extending outwardly from a top portion of the interior wall.
9. The light fixture of claim 8 , wherein a bottom edge of the interior wall abuts a top surface of the bottom wall.
10. The light fixture of claim 1 , wherein the outer wall of shroud and the bottom wall have annular configurations.
11. The light fixture of claim 10 , wherein at least a portion of an outer wall of the housing and at least a portion of the outer wall of the shroud have frusto-conical configurations that are aligned with one another.
12. The light fixture of claim 1 , wherein the indirect lighting array is oriented to project light along axes extending perpendicular to the downward axis.
13. The light fixture of claim 12 , wherein the bottom wall has a planar configuration aligned with the axes of the indirect lighting array.
14. The light fixture of claim 1 , wherein the shroud further comprises a coupling wall extending upwardly from the outer wall; and the housing comprises a channel sized to receive the lock wall therein to interlock the shroud with the housing.
15. The light fixture of claim 1 , wherein the housing further comprises a top wall configured to be mounted to a substrate of a building.
16. The light fixture of claim 1 , further comprising a mounting rod, the housing coupled to the mounting rod to thereby secure the light fixture to a substrate of a building.
17. The light fixture of claim 1 , wherein light emitted from the indirect lighting array is incident upon an interior edge of the bottom wall.
