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.

Claims (33)

1. 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.

2. The auxiliary ring of claim 1 , further comprising a first power source configured to provide power to the one or more light sources.

3. The auxiliary ring of claim 2 , wherein the first power source is a DC power source.

4. The auxiliary ring of claim 1 , wherein the light emitted by the one or more light sources is diffused by at least one of a diffuser and air.

5. The auxiliary ring of claim 1 , wherein the perimeter surface is parallel to each of the proximal plane portion and the distal plane portion, wherein the perimeter surface comprises an edge which defines a downlight plane, wherein the downlight is configured to emit light adjacent a distal-most point of the perimeter surface that does not extend beyond the downlight plane, wherein the one or more light sources are configured to emit light external to the perimeter surface.

6. The auxiliary ring of claim 1 , wherein the one or more light sources are configured to operate at least two of an on state, an off state and a scalable dimmer state, and the downlight is configured to operate in at least two of an on state, an off state, and a scalable dimmer state.

7. The auxiliary ring of claim 6 , further comprising a controller, the controller configured to control operational states of each of the one or more light sources of the auxiliary ring and the downlight.

8. The auxiliary ring of claim 1 , wherein the one or more light sources emit light in a direction opposite to light emitted by the downlight.

9. The auxiliary ring of claim 1 , wherein the one or more light sources comprise at least one of a light-emitting diode (LED) and an organic light-emitting diode (OLED).

10. The auxiliary ring of claim 1 , wherein the one or more light sources are positioned on the distal portion at substantially equal radii from a center of the downlight.

11. The auxiliary ring of claim 1 , wherein the proximal portion is configured to engage a top surface of the downlight and a mounting surface.

12. The auxiliary ring of claim 1 , wherein the proximal portion is configured to engage a bottom surface of the downlight.

13. 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.

14. The illumination system of claim 13 , further comprising a diffuser, the diffuser positioned external to the downlight and configured to receive light emitted by the one or more light sources.

15. The illumination system of claim 14 , wherein the one or more light sources are configured to emit light independent of the downlight.

16. The illumination system of claim 14 , wherein both the downlight and the one or more light sources are dimmable.

17. The illumination system of claim 13 , further comprising a controller, the controller configured to control operational states of each of the one or more light sources and the downlight.

18. The illumination system of claim 14 , wherein the one or more light sources comprise at least one of a light-emitting diode (LED) and an organic light-emitting diode (OLED).

19. 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.

20. The auxiliary ring of claim 19 , wherein the outer perimeter surface is parallel to each of the planar proximal portion and the distal planar portion, wherein the perimeter surface comprises an edge which defines a downlight plane, wherein the downlight is configured to emit light adjacent a distal-most point of the perimeter surface that does not extend beyond the downlight plane.
