Abstract: A rotatable connection for securing a light module to a supporting structure is described herein. The light module directs light towards an illumination area. The light module is directable by rotating the light module using the rotatable connection. The rotatable connection includes an upper connector and a base. The upper connector and the base may secure together with a tool-less connection. the upper connector couples to the light module through a rotatable connection that enables rotation of the light module without use of tools and also resists rotation of the light module after the light module has been installed at a particular angle.

Abstract: A light fixture includes a housing defining a channel and an insert lighting module. The insert lighting module includes an insert housing, a visible light engine coupled to a bottom portion of the insert housing for emitting visible light for general illumination, and an auxiliary light module coupled to the insert housing and including an auxiliary light engine for emitting germicidal light effective in deactivating pathogens. A top portion of the insert lighting module may be positioned within the channel and the insert lighting module may be coupled to the housing. The auxiliary light module may be uncoupled and removed from the insert housing by performing the steps of: uncoupling the insert lighting module from the housing and removing the insert lighting module from the channel, and uncoupling the auxiliary light module from the insert housing and removing the auxiliary module from the top portion of the insert housing.

Abstract: A software tool automatically generates a components list (also known as a “solution”, “recipe”, or “bill of materials”) to be used in completing an installation. This components list may include, for example, fixtures and control devices for use in implementing lighting solutions for a building. The system takes as input a sequence of operations table, and identifies components to satisfy the requirements specified in the sequence of operations table. A number of different solutions may be presented, offering different configurations, cost levels, product lines, and/or the like; the different solutions may also indicate different degrees to which controls are embedded in fixtures. The user can then select among the presented solutions, and/or can perform other operations to change the configuration and/or parameters so as to generate new options.

Abstract: Battery charge function may be in an LED driver which eliminates the duplication of line interface circuitry. A single line interface circuit provides the input power conversion for both the battery charge function and normal operation of the LED driver. During a loss of power, the LEDs may be controlled using power from the battery backup module.

Abstract: A lighting relay panel may include lower-cost features or components related to improved safety and reliability. In some cases, the relay panel includes a power supply capable of protecting the panel from high-voltage and high-current transients. A microcontroller may determine a power interruption based on a zero-cross signal received from the power supply, and may also configure latching relays during the interruption. In some implementations, the relay panel includes a relay sense circuit that is capable of receiving actuation signals from multiple relays connected to different phases of a power signal, and the microcontroller may synchronize or repeat the actuations based on a signal from the relay sense circuit. The microcontroller may generate relay addresses based on the relay positions within the relay panel. In some cases, the relay panel may include isolation circuits that are capable of providing an isolated control signal having an improved voltage range.

Abstract: Certain aspects involve a lighting fixture including multiple de-saturated color LED groups and in which the color temperature and intensity of the generated light can be selectively modified. The lighting fixture is driven by a multi-channel driver that independently controls the multiple de-saturated color LED groups. In one example, the de-saturated color LED groups are made with the same Indium gallium nitride (InGaN) LED, as to maintain all electrical/thermal characteristics. The color temperature and intensity of the lighting fixture are adjusted by managing the intensity of each of the de-saturated color LED groups according to a lookup table or a formula describing the relationship between the intensities of the de-saturated color LED groups and the color temperature and intensity of the lighting fixture. Because de-saturated color LEDs are used in the lighting fixture, dynamic dimming or “warm dim” can be achieved to replicate the effect of an incandescent lamp.

Abstract: An alignment system for a linear light fixture includes multiple light elements. Each light element includes a top surface that defines a top channel. Each light element includes an endcap that defines apertures that extend through an entire thickness of the endcap. A top surface of each endcap defines an endcap channel. A hanger insert is positionable between the endcaps of two light elements. The hanger insert defines additional apertures. A top surface of the hanger insert defines an insert channel and a hanger connection. The top channels, the endcap channels, and the insert channel form an elongate channel. The system includes pins that are configured to extend through the apertures of the endcaps and the hanger insert. The system includes a connector plate that is configured to be received and secured within the elongate channel. The connector plate defines a central aperture that provides access to the hanger connection.

Abstract: A lighting fixture for powering multiple LED groups to generate a selectable color temperature. The lighting fixture provides varying amounts of power to each group of LEDs to achieve a selected color temperature. Current from a driver may be divided between the LED groups based on a selected operational state, which is selected using a switch or other configurable input. The operational states may turn the LED groups on or off or may control an amount of current received by the LED groups. In some configurations, all of the LED groups are always at least partially powered.

In certain aspects, the sensor module is configured to support a power source on the sensor module. In some cases, the sensor is an indoor sensor.

Abstract: An emergency LED lighting system maintains power to an LED lighting source based on measured voltages and currents provided to the LED lighting source; rolls back or decreases power provided to an LED lighting source over time in order to increase the amount of time the battery can power the LED lighting source; executes a soft start procedure, such that the power provided to the LED lighting source is gradually ramped up during activation of the LED lighting sources; identifies a type of battery coupled to the emergency LED lighting system; cycles the emergency LED lighting system between charging mode and standby mode to reduce power consumption over a window of time; detects AC power or an absence of AC power; and/or uses a status LED to communicate information about the emergency LED lighting system with a remote device.

Abstract: A non-glare luminaire includes a toroidal-shaped light engine having light emitting diodes (LEDs) disposed about the light engine in a radial pattern. The light engine has an axial direction that is at least substantially orthogonal to the surface of the light engine. An anti-glare ring is disposed proximate the light engine and includes reflectors arranged in a radial pattern. Each reflector is configured to reflect tangentially oriented light from at least one of the LEDs substantially along the axial direction. The luminaire also includes a toroidal integrated optic (TIO), which is made up of a total internal reflectance (TIR) lens that is coupled with a light guide. The TIO optic has a toroidal lens portion having a light entrance side that receives light from the LEDs and the reflectors. The optic collimates the light received from the LEDs and the reflectors and emit the light via a light exit side.
