Abstract

A luminaire with uplighting and downlighting capabilities is provided. According to one aspect, the luminaire may include a housing, a light source disposed in the housing, and a lens. The light source may be configured to emit light in a downward direction, and the lens may at least partially cover the light source. An opening may be formed in a top part of the housing and may permit light reflected by an interior surface of the lens to be transmitted in an upward direction from the housing. Optionally, a transparent or translucent cover member may at least partially cover the opening in the top part of the housing.

Claims (27)

1. A luminaire comprising:

a housing having a bottom end including a first opening and a top end including a second opening, wherein the bottom end includes an inwardly extending lip which at least partially surrounds the first opening and defines an exterior surface of the luminaire;

a light source disposed in the housing and configured to emit light in a downward direction toward the first opening;

a first optic at least partially covering the first opening, wherein the first optic does not extend vertically below the inwardly extending lip of the bottom end of the housing; and

a second optic at least partially covering the second opening and having an optic bottom end and an optic top end, the optic bottom end being disposed radially outwardly of the optic top end.

2. The luminaire of claim 1 , the second optic being arranged above the first optic.

3. The luminaire of claim 1 , the second optic being centered about a vertical axis.

4. The luminaire of claim 3 , the second optic including a wall extending between the bottom end and the top end, wherein the wall has a substantially constant angle of inclination relative to the vertical axis.

5. The luminaire of claim 4 , the second optic having a truncated cone shape.

6. The luminaire of claim 1 , at least a portion of the second optic being arranged above the light source.

7. The luminaire of claim 1 , the second optic being configured to diffusively transmit light in an upward direction.

8. The luminaire of claim 1 , the second optic being translucent.

9. The luminaire of claim 1 , the second optic being transparent.

10. The luminaire of claim 1 , an outer peripheral portion of the housing being disposed radially outwardly of the first optic, wherein the second opening is formed at least partially in the peripheral portion of the housing.

11. The luminaire of claim 1 , the first optic including a center portion and an outer peripheral portion, the outer peripheral portion of the first optic surrounding a cavity defined between the center portion of the first optic and the light source.

12. The luminaire of claim 11 , the outer peripheral portion of the first optic extending from the center portion of the first optic toward the light source and being at least partially disposed in the housing.

13. The luminaire of claim 12 , the outer peripheral portion of the first optic being suspended from a mounting assembly disposed in the housing.

14. The luminaire of claim 13 , the outer peripheral portion of the first optic spanning at least a portion of a distance separating the mounting assembly and the first opening.

15. The luminaire of claim 11 , the first optic including a step-shaped shoulder portion connecting the center portion and the outer peripheral portion.

16. The luminaire of claim 15 , the step-shaped shoulder portion including a downwardly facing surface positioned above and spaced apart from an upwardly facing interior surface of the housing.

17. The luminaire of claim 16 , the outer peripheral portion of the first optic being centered around a vertical axis, and an interior surface of the center portion of the first optic being substantially perpendicular to the vertical axis.

18. The luminaire of claim 1 , the first optic being capable of optical diffusion.

19. A luminaire comprising:

a housing having a bottom end including a first opening and a top end including a second opening, wherein the bottom end includes an inwardly extending lip which at least partially surrounds the first opening and defines an exterior surface of the luminaire;

a light source disposed in the housing and configured to emit light in a downward direction toward the first opening;

a first optic at least partially covering the first opening, the first optic including a center portion and an outer peripheral portion, the outer peripheral portion of the first optic surrounding a cavity defined between the center portion of the first optic and the light source; and

a second optic at least partially covering the second opening and having an optic bottom end and an optic top end, the optic bottom end being disposed radially outwardly of the optic top end.
