SOLID STATE LIGHTING DEVICE WITH ELECTRONICALLY ADJUSTABLE LIGHT BEAM DISTRIBUTION
First Claim
1. A solid-state lamp comprising:
- a light source module comprising;
a printed circuit board (PCB); and
a plurality of solid-state emitters populated over the PCB in a matrix arrangement comprising at least one row and at least one column, wherein at least one solid-state emitter of the plurality is addressable at least one of individually and in one or more groupings to customize its emissions;
one or more optics configured to be optically coupled with the light source module and to transmit output thereof, wherein the one or more optics comprises at least a first optical layer disposed over the at least one solid-state emitter and configured to focus emissions thereof and a second optical layer disposed over the at least one solid-state emitter and configured to convert emissions thereof to emissions of different wavelengths, and wherein the first optical layer is disposed directly on the at least one solid-state emitter, and the second optical layer is disposed directly on the first optical layer; and
a controller configured to be communicatively coupled with the at least one solid-state emitter and to output a control signal to electronically control emissions of the at least one solid-state emitter so as to provide pixelated control over light distribution of the solid-state lamp.

Abstract
A lighting device including one or more solid state light sources having an electronically adjustable light beam distribution is disclosed. The lighting device may be a lamp configured to include one or more light source modules, each including one or more solid-state emitters populated over a printed circuit board (PCB). The lamp further may include one or more optics configured to modify the output of its one or more light source modules. For a given module, the one or more emitters thereof may be arranged, for example, in a matrix, cellular array, concentric array, or other arrangement, as desired for a given target application or end-use. A given emitter may be addressable individually, in one or more groupings, or both. In some cases, a lamp provided as described herein may be configured for retrofitting existing lighting structures.
