Abstract

Solid-state lamps having an electronically adjustable light beam distribution are disclosed. In accordance with some embodiments, a lamp configured as described herein includes a plurality of solid-state emitters (addressable individually and/or in groupings) mounted over a non-planar interior surface of the lamp. The interior mounting surface can be concave or convex, as desired, and may be of hemispherical or hyper-hemispherical geometry, among others, in accordance with some example embodiments. In some embodiments, the heat sink of the lamp may be configured to provide the interior mounting surface, whereas in some other embodiments, a separate mounting interface, such as a parabolic aluminized reflector (PAR), a bulged reflector (BR), or a multi-faceted reflector (MR), may be included to such end. Also, the lamp may include one or more focusing optics for modifying its output. In some cases, a lamp provided as described herein may be configured for retrofitting existing lighting structures.
