Abstract:

A reflector assembly for a solid-state luminaire is disclosed. The disclosed reflector assembly may be configured, in accordance with some embodiments, to be disposed over a given printed circuit board (PCB) of a host luminaire such that emissions of emitters populated over that PCB are reflected out of the luminaire via the reflector assembly. In some embodiments, the reflector assembly may be formed from one or more reflective members, which may be generally bar-shaped or cup-shaped, or other example configurations. In some other embodiments, the reflector assembly may be formed from a bulk body having one or more reflective cavities formed therein. The particular configuration of a given reflective member or reflective cavity, as the case may be, of the reflector assembly, as well as the particular arrangement thereof for a host luminaire, may be customized as desired for a given target application or end-use.

International Classification:

F21K 99/00
H05B 37/02
F21V 29/00
H05B 33/08

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.

Abstract:

A luminaire having an electronically adjustable light beam distribution is disclosed. In accordance with some embodiments, the disclosed luminaire includes a housing, for example, of hemi-cylindrical, oblate hemi-cylindrical, oblong elliptical, or polyhedral shape. The disclosed luminaire also includes a plurality of solid-state light sources arranged over its housing, in accordance with some embodiments. The one or more solid-state emitters of a given solid-state light source may be addressable individually and/or in one or more groupings, in some embodiments. As such, the solid-state light sources can be electronically controlled individually and/or in conjunction with one another, providing for highly adjustable light emissions from the host luminaire, in accordance with some embodiments. One or more heat sinks may be mounted on the housing to assist with heat dissipation for the solid-state light sources. The luminaire can be configured, for example, to be mounted or as a free-standing lighting device, as desired.

F21K 99/00

Abstract:

A luminaire having a plurality of power sockets arranged over its housing is disclosed. In some embodiments, the luminaire includes a driver operatively coupled with all (or some sub-set) of the power sockets and configured to control the light output of a modular solid-state light source operatively interfaced therewith. In some such embodiments, the luminaire also includes a power-line communication (PLC) module configured to output a PLC signal utilized by the driver in controlling the modular light source's output. In some other embodiments, the modular light source includes the driver, which may utilize a PLC signal, a command signal received from a remote source, or both, in controlling light output. In some cases, the modular solid-state light sources may allow the luminaire to produce a target light beam distribution utilizing a minimal or otherwise reduced quantity of such light sources, reducing cost and difficulty of installation and commissioning.

Abstract:

Techniques and user interfaces (UIs) are disclosed for controlling a solid-state luminaire having an electronically adjustable light beam distribution. The disclosed UI may be configured, in accordance with some embodiments, to provide a user with the ability to control, by wireless and/or wired connection, the light distribution of an associated solid-state luminaire in a given space. The UI may be hosted by any computing device, portable or otherwise, and may be used to control any given light distribution capability provided by a paired luminaire. In accordance with some embodiments, the user may provide such control without need to know details about the luminaire, such as the quantity of solid-state lamps, or their individual addresses, or the address of the fixture itself. In some cases, the disclosed techniques may involve acquiring spatial information of the space that hosts the luminaire and/or providing user-selected distribution of light within that space.
