Abstract

Disclosed is an LED luminaire, comprising a housing positionable at a building structure location. The housing has at least one light output boundary and configured to direct light therein toward the light output boundary. A light guide configured to be located at the light output boundary to receive light operationally contained within the housing, so as to emit non-directional light at the light output boundary. At least one first LED light engine is located within the housing, the at least one first LED light engine including at least one first LED light source to emit directional light at the light output boundary.

Claims (20)

1. An LED luminaire, comprising:

a. a luminaire housing defining a light output region;

b. a light guide configured to be located at the light output region, the light guide defining at least one directional light source location thereon;

c. at least one LED light engine located within the luminaire housing, comprising:

i. at least one first LED light source; and

ii. a shroud having a shroud periphery and configured to operatively position the first LED light source therein and inwardly spaced from the shroud periphery;

iii. the shroud periphery being positionable adjacent the light guide at the directional light source location, to deliver directional light via the directional light source location to a target location, in a target region beyond the luminaire;

iv. the light guide being configured to optically couple with the first LED light source in the housing to define a non-directional light output to deliver non-directional light.

2. The LED luminaire of claim 1 , wherein the at least one directional light source location includes a plurality of directional light source locations and the at least one LED light engine includes a plurality of LED light engines, each associated with a corresponding one of the directional light source target locations.

3. The LED luminaire of claim 2 , wherein the directional light source locations are arranged in a designated pattern on the light guide.

4. The LED luminaire of claim 1 , wherein the shroud periphery is secured to the light guide.

5. The LED luminaire of claim 4 , wherein the shroud periphery includes a flange which is fused to a surface of the light guide.

6. The LED luminaire of claim 1 , wherein the at least one directional light source location includes a passage through the light guide.

7. The LED luminaire of claim 6 , wherein at least one of the first LED light source and the shroud is configured to deliver directional light transversely through the passage.

8. The LED luminaire of claim 1 , wherein the optical coupling is between the first LED light source and the light guide along a path external to the shroud.

9. An LED luminaire comprising a housing positionable at a building structure location, the housing having at least one light output boundary and configured to direct light therein toward the light output boundary, a light guide configured to be located at the light output boundary to receive light operationally contained within the housing, so as to emit non-directional light at the light output boundary, and at least one first LED light engine located within the housing, the at least one first LED light engine including at least one first LED light source to emit directional light at the light output boundary and to provide the light operationally contained within the housing, wherein the at least one first LED light engine includes a reflective shroud to emit the directional light toward a directional light source location on the light guide.

10. The luminaire of claim 9 , wherein the shroud is in contact with an internally exposed surface of the light guide.

11. The luminaire of claim 10 , wherein the shroud is affixed to the internally exposed surface.

12. The luminaire of claim 9 , wherein the directional light source location includes a passage through the light guide.

13. The luminaire of claim 9 , wherein the shroud is configured to emit a portion of light from the first LED light source into the housing to provide the light operationally contained within the housing.
