Abstract

A luminaire having an electronically adjustable light beam distribution is disclosed. In some embodiments, the disclosed luminaire includes a plurality of solid-state lamps mounted on one or more surfaces of a housing. The lamps can be electronically controlled individually and/or in conjunction with one another, for example, to provide highly adjustable light emissions from the luminaire (e.g., pixelated control over light distribution). In some cases, a given solid-state lamp may include tunable electro-optic componentry to provide it with its own electronically adjustable light beam. One or more heat sinks optionally may be mounted on the housing to assist with heat dissipation for the solid-state lamps. The luminaire can be configured to be mounted or as a free-standing lighting device, in accordance with some embodiments. In some embodiments, the aperture through which the lamps provide illumination is smaller than the distribution area of the solid-state lamps of the luminaire.

First claim

What is claimed is:

1. A luminaire comprising:
a housing;
a plurality of solid-state lamps arranged on the housing, wherein light emitted by the plurality of solid-state lamps exhibits a one-to-one mapping of the solid-state lamps to beam spots produced thereby;
a controller communicatively coupled with the plurality of solid-state lamps and configured to provide pixelated control over light distribution of the luminaire, wherein the controller is configured to electronically control at least a beam direction of each of the plurality of solid-state lamps independently of one another via an electro-optic tunable lens optically coupled to each of the plurality of solid-state lamps; and
a touch-sensitive device configured to communicatively couple to the controller and send an input received by the touch-sensitive device to the controller to individually control each of the plurality of solid-state lamps to thereby provide the pixelated control over light distribution of the luminaire.

2. The luminaire of claim 1 , wherein the housing has a concave interior surface, and wherein the plurality of solid-state lamps is arranged on the concave interior surface of the housing.

3. The luminaire of claim 1 , wherein the housing has a plurality of planar interior surfaces, and wherein the plurality of solid-state lamps is arranged on one or more of the plurality of planar interior surfaces.

4. The luminaire of claim 1 , wherein the housing has a convex exterior surface, and wherein the plurality of solid-state lamps is arranged on the convex exterior surface of the housing.

5. The luminaire of claim 1 , wherein the housing has a plurality of planar exterior surfaces, and wherein the plurality of solid-state lamps is arranged on one or more of the plurality of planar exterior surfaces.

6. The luminaire of claim 1 further comprising one or more heat sinks arranged on an exterior surface of the housing and coupled with the plurality of solid-state lamps through a wall of the housing.

7. The luminaire of claim 1 further comprising one or more heat sinks arranged on an interior surface of the housing and coupled with the plurality of solid-state lamps through a wall of the housing.

8. The luminaire of claim 1 , wherein the controller is further configured to control at least one of beam angle, beam diameter, beam distribution, brightness, and/or color of light emitted by at least one of the plurality of solid-state lamps.

9. The luminaire of claim 1 , wherein the controller utilizes at least one of a digital multiplexer (DMX) interface protocol, a Wi-Fi protocol, a digital addressable lighting interface (DALI) protocol, and/or a ZigBee protocol.

10. The luminaire of claim 1 , wherein at least one of the plurality of solid-state lamps includes a light-emitting diode (LED), and wherein the controller is configured to control that LED.

11. The luminaire of claim 1 , wherein at least one of the plurality of solid-state lamps includes at least one of a fixed lens, a reflector, a diffuser, a polarizer, a brightness enhancer, and/or a phosphor material.

12. The luminaire of claim 1 , wherein the luminaire is configured to be mounted on a mounting surface comprising a drop ceiling tile, a ceiling, a wall, a floor, or a step.

13. The luminaire of claim 1 , wherein the luminaire is configured as a free-standing lighting device.

14. A luminaire comprising:
a housing having one or more interior surfaces;
a plurality of solid-state lamps arranged on the one or more interior surfaces of the housing, wherein light emitted by the plurality of solid-state lamps exhibits a one-to-one mapping of the solid-state lamps to beam spots produced thereby, and wherein at least one of the plurality of solid-state lamps comprises:
one or more light-emitting diode (LEDs) populated on a printed circuit board (PCB);
an electro-optic tunable lens optically coupled with the one or more LEDs; and

one or more heat sinks arranged on an exterior surface of the housing and coupled with the plurality of solid-state lamps through a wall of the housing; and
a touch-sensitive device configured to communicatively couple via a controller to the plurality of solid-state lamps and configured to individually control each of the plurality of solid-state lamps, wherein the controller is configured to electronically control at least a beam direction of each of the plurality of solid-state lamps independently of one another via the electro-optic tunable lens, and wherein the touch-sensitive device is configured to send an input received by the touch-sensitive device to the controller to individually control each of the plurality of solid-state lamps independently of one another.

15. The luminaire of claim 14 further comprising the controller.

16. The luminaire of claim 15 , wherein the controller is populated on the PCB of at least one of the plurality of solid-state lamps and configured to electronically control the one or more LEDs populated on that PCB.

17. The luminaire of claim 14 further comprising an electro-optic tunable lens optically coupled with the plurality of solid-state lamps and configured to adjust accumulated light distribution.

18. A luminaire comprising:
a housing having one or more exterior surfaces;
a plurality of solid-state lamps arranged on the one or more exterior surfaces of the housing, wherein light emitted by the plurality of solid-state lamps exhibits a one-to-one mapping of the solid-state lamps to beam spots produced thereby, and wherein at least one of the plurality of solid-state lamps comprises:
