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.
