Abstract

Disclosed herein are cove lighting apparatus for architectural surfaces, particularly, recessed cove lighting apparatus integrated with an architectural surface and employing LED-based light sources.

Claims

1. A cove lighting apparatus for an architectural surface, comprising:

a cove member configured to fit within a gap defined by the architectural surface and comprising an interior surface that is recessed from the architectural surface; and

at least one LED-based light source associated with the cove member for irradiating at least a portion of the interior surface with visible light perceivable by a viewer via the gap defined in the architectural surface,

wherein the cove lighting apparatus is configured such that the at least one LED-based light source is concealed from the viewer.

2. The apparatus of claim 1, wherein the cove member includes a channel portion, and wherein:

the at least one LED-based light source is coupled to the channel portion and positioned so as to irradiate at least the portion of the interior surface of the cove member with the visible light.

3. The apparatus of claim 2, further comprising a blocking member for concealing the at least one light LED-based source from the viewer.

4. The apparatus of claim 1, wherein the at least a portion the interior surface of the cove member comprises an essentially white matte surface configured to reflect and diffuse light.

5. The apparatus of claim 4, wherein the at least one LED-based light source is positioned with respect to the cove member such that the visible light is perceivable as a light surface that is essentially flush with the architectural surface.

6. The apparatus of claim 1, wherein the color of the visible light includes at least one non-white color.

7. The apparatus of claim 1, wherein the visible light includes essentially white light.

8. The apparatus of claim 1, further including at least one controller coupled to the at least one light source and configured to control at least one of a color, a color temperature and an intensity of the visible light.

9. The apparatus of claim 8, further including at least one user interface coupled to the at least one controller and configured to facilitate control of the at least one of the color, the color temperature, and the intensity of the visible light.

10. The apparatus of claim 8, wherein the at least one LED-based light source comprises:

at least one first LED for generating first radiation having a first spectrum; and

at least one second LED for generating second radiation having a second spectrum different from the first spectrum.

11. The apparatus of claim 10, wherein the at least one controller independently controls a first intensity of the first radiation and a second intensity of the second radiation so as to control at least one of the color, the color temperature and the intensity of the visible light.

12. The apparatus of claim 11, wherein the at least one first LED includes at least one first white LED.

13. The apparatus of claim 12, wherein the at least one second LED includes at least one second white LED.

14. The apparatus of claim 1, wherein the visible light is perceived by the viewer as substantially uniform filing the gap in the architectural surface.

15. A method for providing architectural illumination, comprising:

forming a gap in an architectural surface;

disposing a cove member in the gap defined by the architectural surface, the cove member comprising an interior surface that is recessed from the architectural surface;

generating visible light by at least one light LED-based source; and

irradiating at least a portion of the interior surface with visible light such that the visible light is perceivable by a viewer via the gap as a light surface that is essentially flush with the architectural surface.
