Abstract: This disclosure describes systems, methods, and apparatus for a customizable and modular LED lighting system. The LED lighting system can include an LED driver coupled to a light run and held rigidly relative to each other via a carrier. A mounting bracket can also attach to the LED driver and/or the light run and can affix the LED lighting system to a junction box. The light run can include a thermally conductive frame, sometimes having a “V”-shape and having two surfaces on an upper portion thereof. A substrate comprising a string of electrically-coupled LEDs can be affixed to each of the two surfaces. The LEDs can be driven by the LED driver and can be coupled to each other serially via one or more electrical connectors.

Abstract: An electrical connection system connecting a flexible conduit to electrical conductors, comprising a conduit portion and a removably attachable base portion. The conduit portion retains an end of the conduit, via a retention mechanism within a first housing at a first end. The conduit portion comprises a first electrical connector housing and electrical terminals within a second end of the first housing. The base portion comprises a base mount and a second housing having a first end pivotably connected to the base mount, the second housing being pivotable at a joint. The base portion may also comprise a second electrical connector housing and electrical terminals within a second end of the second housing for electrical connection to the conduit portion. Mechanical fastening components of the base portion and the conduit portion enable a mechanical connection between the base portion and the conduit portion.

Abstract: This disclosure describes systems, methods, and apparatus for an LED driver circuit capable of responding to dimmer signals from three different types of dimmers: a phase cut dimmer, a dedicated dimmer (e.g., 0-10V dimmer), and a button dimmer. The processor can include inputs for each of these dimmer types, and can be configured to determine which of the three types of dimmers is controlling the LED driver circuit, and determine which dimming signals to respond to when more than one dimmer type is trying to control the LED.

Abstract: 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—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.

A method provided by the system includes (a) providing a forward drive current to power the LED, the forward drive current having a first LED operating current component; (b) detecting the first LED operating current component; (c) sensing a first thermal operating point of the LED; and (d) generating a temperature signal indicative of the first thermal operating point. The method also includes (e) determining a thermal operating range of the LED; (f) determining that the first thermal operating point of the LED is outside the thermal operating range of the LED; and (g) generating a first control setting configured to cause the LED to be driven at a second operating point, the second thermal operating point within the thermal operating range.

Abstract: Compensating for disturbances in light output by a light source includes sensing light output by a light source and generating a light-sense signal based thereon, detecting a disturbance in the light-sense signal, and generating an output signal to compensate for the disturbance. An LED is driven in accordance with the periodic output signal to thereby compensate for the periodic disturbance.

Abstract: Light sources with arrangements of multiple LEDs (or other light-emitting devices) disposed at or near the focus of a reflecting optic having multiple segments facilitate varying the angular distribution of the light beam (e.g., the beam divergence) via the drive currents supplied to the LEDs.

Abstract: Faceted optics for use in conjunction with (typically planar) arrangements of discrete light sources (e.g., an array of multiple LED dies) improve or optimize the trade-off between beam divergence and beam non-uniformity, and between non-uniformities resulting from the imaging of the extended light source and artifacts introduced by the optic itself.

Abstract: In various embodiments, a system for providing an LED illumination source on a surface includes a light module comprising (i) an illumination area for receiving one or more light-emitting diodes (LEDs) and (ii) slip joints at first and second ends of the light module, each slip joint comprising a slip joint slot, and at least one bracket for mounting the light module to the surface, the at least one bracket having (i) a fitting frictionally receivable within one of the slip joint slots and (ii) a mounting region engageable to the surface.

Abstract: Thermally managing at least one light-emitting diode (LED) receiving an operating current and/or an operating voltage and being operable at an operating temperature includes determining a current thermal operating point of the LED, obtaining a thermal operating range of the LED, and calculating a new operating point of the LED based on the current thermal operating point and the thermal operating range, wherein the new operating point is within the thermal operating range. A control signal is generated that adjusts power delivered to the LED to cause the LED to operate at the new operating point. Detection of the operating temperature of the LED may be based on the magnitude of a current pulse superimposed on the operating current provided to the LED and the magnitude of the voltage pulse across the LED resulting from the applied current pulse superimposed on the operating current.

Abstract: A switching converter detects when a dimmer circuit supplying power to the switching converter changes from a conducting state to a nonconducting state or from a nonconducting state to a conducting state; an equivalent input resistance of the switching converter is changed to a first, higher value when the dimmer circuit is in the conducting state and to a second, lower value when the dimmer circuit is in the nonconducting state, thereby drawing a minimum current from the dimmer circuit while the dimmer circuit is in the nonconducting state.
