Abstract
A luminaire can comprise a central opening through which cooling air flows. A lens can extend circumferentially about the central opening. A frame can extend circumferentially about the lens. Cooling air can further flow in a gap between the lens and the frame. Light emitting diodes can emit light towards the lens, and the light can pass through the lens. The frame can provide the luminaire with a disk form, or another appropriate geometry.

A luminaire comprising:
- a frame comprising:
- an upper side;
- a lower side;
- and
- a first opening that extends between the upper side and the lower side;
- an optic that is disposed at the lower side of the frame and that comprises a second opening disposed adjacent the first opening;
- and
- a plurality of light emitting diodes that are disposed between the optic and the upper side and that are arranged to emit light onto the optic.

A luminaire comprising:
- a lens comprising:
- a central opening;
- an outer edge that extends about the central opening;
- and
- a light-emitting area that extends between the central opening and the outer edge;
- a plurality of light emitting diodes oriented to illuminate the light-emitting area of the lens;
