Abstract
A downlight auxiliary ring device and method of control and use of same is disclosed. Specifically, the downlight auxiliary ring device, comprising light-emitting diodes, allows a dimmable and reduced-glare reflected downlight. It is also an aspect of the present disclosure to provide easy-to-implement and cost-effective methods of control and use of the downlight auxiliary ring device system.
Claims20
An auxiliary ring comprising:
- a body forming a ring having a central axis, the body comprising:
- a proximal planar portion configured to attach to a perimeter surface of a downlight having a downlight emission direction, the perimeter surface of the downlight terminating at a first radial with respect to the central axis, the proximal planar portion extending beyond the first radial away from the central axis:
- and
- a distal planar portion configured to receive one or more light sources, the distal planar portion disposed at a second radial with respect to the central axis, wherein the second radial extends farther from the central axis than the first radial wherein the one or more light sources are disposed on the distal planar portion;
- wherein the proximal planar portion and the distal planar portion are parallel, and
- wherein the one or more light sources have an emission direction different than the downlight emission direction.

An illumination system comprising:
- a downlight configured to emit a first light, the downlight having a central axis and comprising an outer flange surface positioned at a distal location of the downlight, the outer flange surface circumscribing and defining an outer boundary of a downlight exit area, the outer boundary terminating at a first radial with respect to the central axis;
- an auxiliary ring comprising:
- a body forming a ring about the central axis, the body comprising a proximal portion with a proximal portion surface, the proximal portion extending beyond the first radial away from the central axis, and a distal portion comprising a distal portion surface, the distal portion at a second radial with respect to the central axis, wherein the second radial extends farther from the central axis than the first radial, wherein one or more light sources are disposed on the distal portion surface, wherein the proximal portion surface is in contact with the outer flange surface, and wherein the one or more light sources are positioned to emit a second light outside and in a direction opposite to light emitted from the downlight exit area.
An auxiliary ring comprising:
- a body forming a ring having a central axis, the body comprising
- a planar proximal portion configured to attach to an outer perimeter surface of a substantially circular downlight having a downlight an emission direction, and
- a distal portion comprising a distal planar surface configured to receive one or more light sources, the body radially extending from the central axis beyond the outer perimeter surface, the distal portion radially extending farther from the central axis than the planar proximal portion:
- one or more light sources disposed on the distal planar surface, wherein the planar proximal portion and the distal planar surface are parallel, and
- wherein the one or more light sources have an emission direction different than the downlight emission direction of the downlight.
