This disclosure describes systems, methods, and apparatus for a combined LED driver and emergency backup battery system. The LED driver can include current regulation circuitry as well as a bus enabling charging and discharging of an energy storage device from and to the bus. A master controller can control charging and discharging of the energy storage device via a controller of an energy storage management system, and also communicate with the current regulation circuitry to control a balance of power between an AC mains, the energy storage device, and driving of an LED light source. Accessories may be coupled to the bus and receive low voltage power from the bus and optionally receive commands from the master controller and provide sensed data back to the controller. A wireless network interface to the master controller can enable system states based on electrical power company indications and instructions.

LED lighting system with battery for demand management and emergency lighting

A light device and method for producing an output light beam are disclosed. A light source assembly comprising a plurality of light sources is arranged at the first end of the light device and emits light towards the second end and parallel with the longitudinal axis of the device. The device also has a chamber for mixing light emitted from the light source assembly; and a concave reflecting optic for redirecting light exiting the chamber and emitted onto the optic. The redirected light forms an output light beam. The device also has driver circuitry for controlling drive currents to the plurality of light sources individually or in groups thereof to thereby variably control a divergence of the output light beam.

Variable beam source with mixing chamber

A method and device for variable-beam illumination are disclosed. The device has a light source, a first reflector segment, and a second reflector segment. The first segment has a first parabolic cross section to produce a first light distribution having a wide-angle light distribution. The second segment has a second parabolic cross section to produce a second light distribution that is narrower than the first light distribution. At least one of the first and second segments is movable between first and second positions. At least a portion of the light is reflected to effectuate the first light distribution when the at least one of the first and second segments is in the first position. At least a portion of the light is reflected to effectuate the second light distribution when the at least one of the first and second segments is in the second position.

Illumination device with adjustable curved reflector portions

Devices and methods for uniform illumination of a target surface are disclosed. A device assembly has a light source configured to be coupled to a mounting surface, and at least one reflector. The reflector is configured to be coupled to at least one of the light source or the mounting surface, and interposed between the light source and the mounting surface, the reflector having a reflective surface area and a plurality of curved reflective segments. The reflector is shaped and arranged relative to the light source such that the reflector directly intercepts and reflects a portion of light emitted by the light source to the target surface to thereby cause substantially uniform illumination of the target surface. The target surface has a surface area that is greater than the reflective surface area of the at least one reflector.

Light source for uniform illumination of a surface

An illumination device comprises a lighting module that itself includes one or more LEDs; a driver module, physically separate from the lighting module, and comprising for supplying power to the one or more LEDs; a flexible conduit electrically connecting the driver module to the lighting module; an air pathway following the conduit; and a cooling facility for directing air through the lighting module and the driver module, such that the air passes through the air pathway.

Integral cooling for LED lighting source

Lamp including an array of LEDs disposed at or near the focus of a reflecting optic having multiple segments with different aiming angles (i.e. the angle corresponding to a reflected beam output direction), and a driver circuit for discretely activating some of the LEDs in the array. The angular distribution of the output light beam (e.g., the beam divergence) is adjusted by selectively changing the currents supplied to the LEDs.

Variable-beam light source with mixing chamber

Embodiments of the invention provide systems and techniques for analyzing an existing light fixture in its installed environment and, based on the sensed location of the light and its environmental illumination pattern, identifying at least one LED retrofit fixture that may be used to replace the existing light fixture.

Lighting audit and LED lamp retrofit

A light source producing a beam of variable divergence, comprising one or more light-emitting devices arranged on a planar substrate, with each of the light-emitting devices having a Lambertian emission distribution. The light source may further comprise a chamber for mixing light emitted from the one or more light-emitting devices, the chamber itself comprising a base defined by the planar substrate, one or more side walls having a reflective interior surface, and a planar diffusive emission surface defining a ceiling of the chamber. The chamber may have an adjustable height. A reflector extends from the chamber for redirecting light exiting from the chamber to form a light beam, the reflector surrounding and having a focal plane coincident with the ceiling of the chamber. Finally, the light source may comprise a mechanism to control a height of the chamber to thereby variably control a divergence of the light beam.

Uniform light source with variable beam divergence

A device has a light source, a first reflector segment having a first parabolic cross section to produce a first light distribution having a wide-angle light distribution, and a second reflector segment having a second parabolic cross section to produce a second light distribution that is narrower than the first light distribution. At least one of the first and second segments is movable between first and second positions such that a portion of the light emitted by the light source is reflected to form the first light distribution when the at least one of the first and second segments is in the first position, and a portion of the light is reflected to form the second light distribution when the at least one of the first and second segments is in the second position.

Thermal management and control techniques for light emitting diode and other incandescent replacement light technologies using a current controller are disclosed.

Light emitting diode replacement lamp

Various systems and methods facilitate internal communication within a lighting module as well as intercommunication among lighting modules over an external network. The network may be a conventional network managed by a central network controller or may be an ad hoc or 'mesh' network&#x2014;i.e., a scalable network architecture in which any lighting module is a node that can communicate with any other module or network-connected device.
