Solid-state luminaire with electronically adjustable light beam distribution
First Claim
1. A luminaire comprising:
- a housing having a hemispherical interior surface and an aperture;
a plurality of solid-state lamps arranged on the hemispherical interior surface of the housing so as to provide a lamp distribution area, wherein each of the plurality of solid-state lamps is configured to emit light through the aperture, and the aperture is smaller in size than the distribution area of the plurality of solid-state lamps on the hemispherical interior surface;
a controller communicatively coupled with each of the plurality of solid-state lamps and configured to output one or more control signals to electronically and individually control light emitted thereby; and
an electro-optic tunable lens disposed within the aperture and configured to adjust accumulated light distribution, wherein the controller is configured to output a control signal which controls the electro-optic tunable lens.

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.

13. A luminaire comprising:
-
a housing having a curved interior surface; a plurality of solid-state lamps arranged on the curved interior surface of the housing and configured to emit light through an aperture of smaller size than a distribution area of the plurality of solid-state lamps on the curved interior surface, at least one of the plurality of solid-state lamps comprising; one or more light-emitting diode (LEDs) populated on a printed circuit board (PCB); and an electro-optic tunable lens optically coupled with the one or more LEDs; 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 controller communicatively coupled with the plurality of solid-state lamps and configured to output one or more control signals to electronically control the plurality of solid-state lamps independently of one another and each electro-optic tunable lens independently. - View Dependent Claims (14, 15, 16, 17, 18, 19)
