Abstract: A light fixture having an upper and lower housing, and a mounting bracket adapted to mount to a junction box. The light fixture has a relatively short mounting bracket for surface mount configurations, and a relatively long mounting bracket for recess mount configurations, and a difference in the height of the long and short mounting brackets is equal to the height of the junction box. In the surface-mount and recess-mount configurations a circumferential edge of the upper housing abuts the mounting surface so the lighting fixture has the same external appearance and size in both configurations. The light fixture also has a pendant mode wherein the upper housing is suspended from the junction box by an elongated support. An enclosure for the junction box has a plurality of cut-outs and covers to accommodate various configurations of surface mounted conduit.

Abstract: A lighting control system for use with LED light fixtures that facilitates precise current overload control to achieve transmission of a maximum amount of power across the low-voltage class II cable. The system using an active power control circuit to limit the power transmitted via the low-voltage cable. The system providing under voltage lockout, programmable soft starting, true short circuit protection, overvoltage shutdown and full dimming with the light fixtures being synchronized with no startup delay.

Abstract: A system for controlling LED light fixtures such that in the event of a loss of the lighting control signal the LED light fixtures may be controlled in a proper and predictable manner. The system includes a Digital Power Module (DPM) that receives the lighting control signal and transmits a control signal to a Fixture Control Module (FCM) connected to the LED lights. In the event the lighting control signal is not received by the DPM, it is adapted to send a backup control signal to the FCM to control the LEDs. Additionally, in the event the DPM fails to send a control signal to the FCM, the FCM is adapted to control the LEDs is a predefined manner such that the LEDs are always functional even with a loss of the input control signal.

Abstract: A lighting system and method includes a light module and control module having analog and digital inputs. The control module sends a lighting control output signal to the light module. A mode selector sets a mode of the control module. In a first mode, the lighting control output signal is based on one analog dimming lighting control input signal provided to an analog input. In a second mode, the lighting control output signal is based on dimming and color lighting control input signals provided to two analog inputs. In a third mode, the lighting output control signal is based on a digital lighting control input signal provided to a digital input. In a fourth mode, the control module determines a selected lighting scene based on a scene selection input signal provided to an analog input, and the lighting output signal is based on the selected lighting scene.

Abstract: A highly configurable and flexible distributed lighting control system that includes a Digital Power Module (DPM) connected to at least one remote/distributed Fixture Control Module (FCM) that controls an associated LED light fixture. The LED light fixture including at least two LEDs that are independently controllable. The LED light fixture adapted to receive various control signals for controlling the at least two LEDs.

Abstract: A distributed lighting control system that minimizes or eliminates standby power usage in a low voltage lighting system where a digital power module is adapted to receive at least one control signal and to transmits an output control signal on one or more output ports to control various fixture control modules each having associated LED light fixtures, the digital power module functioning to shut off the transmission of electrical power to the fixture control modules to prevent standby power usage by the fixture control modules.

Abstract: A lighting control system that allows for flexible control of low-voltage LED light fixtures connected to an output of a digital power module such that during “normal” operation where the digital power module is receiving electrical power from the building electrical system, the digital power module controls the connected light fixtures according to a first control scheme and in the event of an interruption of building electrical power (“emergency” operation), the system receives backup power and control the connected light fixtures according to a second control scheme.

Abstract: A lighting fixture for a suspended ceiling including a grid of rails and hub forming an opening in the suspended ceiling has a housing with a mounting clip operable to toollessly mount to a vertical portion of a rail from above with a cam to resiliently expand the mounting clip laterally during mounting of the housing onto the rail, a light unit support connected to the housing and operable to toollessly mount to the hub, from above, and a light unit operable to toollessly mount to the light unit support, through the hub, from below the suspended ceiling.

Abstract: A lighting module for a recessed light fixture has a housing and a light module body movably coupled to the housing by a linkage. In an intermediate tilted position, an optical axis of the light module body is aligned at a first angle relative to a Y axis, and in a fully-tilted limit position, the optical axis is aligned at a second angle relative to the Y axis. Movement of the light module body relative to the housing includes rotation about a Z axis and translation parallel to X and Y axes. During movement of the light module body relative to the housing a first lateral section of a peripheral edge defining an opening of the light module body remains substantially parallel to the Z axis and maintains a substantially constant perpendicular distance from the X axis.

Abstract: A digital control module that is used to power LED light fixtures connected thereto, the digital control module allowing for the continued control and powering of some or all of the connected LED light fixtures even in the event that one of the DC power supplies in the digital control module fails.

Abstract: A light fixture has a frame with an aperture and an enclosure having a driver compartment and a junction compartment. The enclosure is movable relative to the frame. In an operation position, the driver and junction compartments are laterally displaced from the aperture and a lighting module is mountable in the aperture from a room-facing side of the light fixture. In a service position, an opening of the driver compartment is laterally aligned with the aperture such that the lighting driver is removably mountable in the driver compartment through the aperture and the opening of the driver compartment, from the room-facing side of the light fixture. In an inspection position, an opening of the junction compartment is laterally aligned with the aperture, and an interior of the junction compartment is visible through the aperture and the opening of the junction compartment, from a room-facing side of the light fixture.

Abstract: A low-profile, recessed light fixture with a housing, a lighting element enclosure with a heat sink, and a junction box containing a lighting driver. The base of the housing has an illumination aperture disposed therein. The heat sink acts as the top of the lighting element enclosure and is movable between an operation position and a service position. In the operation position, the heat sink is vertically aligned with the illumination aperture. In the service position, the heat sink is horizontally displaced from vertical alignment with the illumination aperture. When the heat sink is in the service position, the interior of the junction box is accessible through the illumination aperture, allowing the user to remove the lighting driver and other electrical components from the junction box for maintenance.

Abstract: A light fixture has a mount to attach the light fixture to a support structure. A yoke is connected to the mount and is operable to rotate relative to the mount at least 360 degrees about a rotation axis passing through an illumination aperture of the light fixture. A lamp is connected to the yoke and is operable to rotate with the yoke about the rotation axis. A proximal end of a junction box is connected to the yoke and is operable to rotate at least 360 degrees relative to the yoke about the rotation axis, to maintain a rotational orientation of the junction box relative to the mount during rotation of the yoke and lamp. The junction box is operable to pivot relative to the yoke, about a pivot axis perpendicular to the rotation axis and to contact the support structure on a distal free end portion.
