1. A luminaire comprising:
- a housing;
a light source disposed in the housing and configured to emit light in a downward direction;
a lens at least partially covering the light source and including a center portion and an outer peripheral portion, the outer peripheral portion extending from the center portion toward the light source and being at least partially disposed in the housing, the outer peripheral portion of the lens surrounding a cavity defined between the center portion of the lens and the light source;
a first opening formed in the housing;
a second opening formed in the housing, the center portion of the lens at least partially covering the second opening; and
wherein an interior surface of the center portion of the lens reflects at least a portion of the light emitted from the light source such that light reflected by the interior surface of the center portion of the lens passes through the outer peripheral portion of the lens and subsequently through the first opening in the housing in an upward direction.

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.

15. A luminaire comprising:
-
a housing including a top part and a bottom part; a means for emitting light in a downward direction toward an opening formed in the bottom part of the housing; a means for diffusively transmitting a first portion of the light in the downward direction; a means for reflecting a second portion of the light in an upward direction; a means for transmitting the second portion of the light through the top part of the housing, the means for transmitting the second portion of the light having an inner surface and an outer surface, wherein the second portion of the light travels through the inner surface and the outer surface; and wherein the means for diffusively transmitting the first portion of the light in the downward direction and the means for transmitting the second portion of the light through the top part of the housing are integrally formed to define a unitary, one-piece structure. - View Dependent Claims (16, 17, 19)
