Concave low profile luminaire with magnetic lighting devices and associated systems and methods
First Claim
1. A luminaire adapted to be carried by a light fixture comprising:
- a generally concave-shaped housing comprising;
an outer surface, and a domed inner surface opposite the outer surface, the inner surface comprising a ferromagnetic material and defining an optical chamber and a substantially circular aperture; and
a plurality of lighting devices each comprising;
a heat sink, a light source in thermal communication with the heat sink; and
a magnetic attachment member comprising a permanent magnet, and configured to proximately fit the inner surface;
wherein the magnetic attachment member is positionable adjacent the inner surface and is configured to magnetically bind to the ferromagnetic material of the housing;
wherein the magnetic attachment member, the heat sink, and the light source are carried by the housing;
wherein each of the plurality of lighting devices is positionable adjacent to and spaced apart about the inner surface of the housing; and
wherein light emitted by the light source of each of the plurality of lighting devices enters the optical chamber and passes through the substantially circular aperture.

Abstract
A luminaire carried by a lighting fixture, having a generally concave-shaped housing defining an optical chamber and an aperture, and a plurality of lighting devices each having a heat sink, a light source, and a magnetic attachment member. Each lighting device may be positioned about the inner surface of the housing. The magnetic attachment member may magnetically bind a lighting device to pads proximate to ferromagnetic material in the housing. Light emitted by the light source may enter the optical chamber and pass through the aperture in a generally orthogonal direction in relation to the orientation of the device. Electrical power may be delivered by one or more power supply units of either an external or an on-board type, and by using either inductive or conductive coupling. Network interfaces may enable communication of control instructions among a multiple controllers located either within a single luminaire or distributed among multiple luminaires.
