Lighting techniques utilizing solid-state lamps with electronically adjustable light beam distribution

摘要

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.

1. A lighting method comprising:
powering first and second solid-state lamps, each such lamp comprising:
a base configured to engage a power socket;a plurality of solid-state emitters arranged over a non-planar interior surface of the lamp, wherein at least one of the solid-state emitters is individually addressable to customize its emissions; andone or more focusing optics optically coupled with the plurality of solid-state emitters; and electronically manipulating beam distribution of the first and second lamps to provide first and second beam distributions, respectively, wherein the first and second beam distributions are different from one another and electronically manipulating beam distribution of the first and second lamps is performed via a control interface configured for communicative coupling with each of the first and second lamps.
