Abstract: An emergency lighting system including a mains power supply, an auxiliary power supply, a brown-out circuit, a plurality of lights including a first group of lights and a second group of lights, and a controller. The brown-out circuit is configured to extract input voltage information related to a voltage level of the mains power supply, and scale down an input voltage of the mains power supply to a DC voltage proportional to the voltage level. The controller is configured to control the plurality of lights. Wherein, power is provided from the mains power supply to the first group of lights and the second group of lights when the DC voltage is above a threshold, and power is provided from the auxiliary power supply to the first group of lights and not the second group of lights when the DC voltage is below the threshold.

Abstract: A luminaire includes a support positioned in a ceiling. A light module is connected to the support having a base, a light emitter, and an optic. The light modules allow different luminaire configurations to be formed out of similar components.

Abstract: A lighting device includes a light source emitting light having a first bandwidth. A single optic device is coupled to the light source. The single optic device filters light having a preselected subrange of wavelengths within the first bandwidth to generate a first filtered light. The single optic device controls a shape of a beam of the filtered light. The filtered light creates a high-intensity narrow-spectrum light output. A second light source emits a high-intensity narrow-spectrum light output.

Abstract: A lighting system including a light source and a controller having an electronic processor and memory. The controller is configured to compare an operational characteristic of the light to a predetermined operational characteristic, and output a signal based on the comparison of the operational characteristic of the light to the predetermined operational characteristic.

Abstract: A luminaire includes a housing having an outer wall and a mounting wall configured to be secured to a structure. The housing further includes a compartment defined at least partially between the outer wall and the mounting wall. The compartment is configured to support a plurality of control devices. A support is coupled to the housing and supports a light emitter assembly. The support includes a plurality of fins in thermal communication with the light emitter assembly. A wall is positioned between the compartment and the plurality of fins.

Abstract: An emergency lighting unit includes a housing. The housing includes a base having a first portion and a second portion. A lamp assembly is rotatably connected to the housing and positioned in the lower portion. A cover is provided over the lamp assembly.

Abstract: A luminaire includes a housing, a light diffusion panel, a reflective surface, and a plurality of light sources. The light diffusion panel includes a light source aperture, an edge surface bounding the light source aperture, and an emission surface. The emission surface includes first and second emission surface sections. The second emission surface section is disposed on an opposite side of the light source aperture from the first emission surface section. The reflective surface is disposed on a side of the light diffusion panel opposite the emission surface. The light sources project light into the light diffusion panel through the edge surface. The light sources include first and second light sources. The first light source projects light into the light diffusion panel and through the first emission surface section. The second light source projects light into the light diffusion panel and through the second emission surface section.

Abstract: Systems and methods for controlling electrical loads in one or more areas. The system includes a room controller having a microprocessor for accessing data and providing commands, memory for storing information operably connected to the microprocessor, a relay for powering a load based on commands from the microprocessor, and a port for connecting a peripheral device. The system also includes a peripheral device connected to the port and configured to send data including a device type and a device instance byte to the controller indicating the type of peripheral device. The device instance byte includes a port number identifying the port and a slot number identifying a time slot within a time domain multiplexing cycle. The system also includes a load connected to the relay.

Abstract: A solid state lighting fixture that can be used in outdoor and indoor recessed lighting applications. The solid state lighting fixture has a recessed housing configured to be installed in a recess, and a solid state light assembly capable of being secured to the housing outside the recess. The solid state light assembly is at least partially made of a heat dissipating material capable transferring heat generated by the solid state light assembly to ambient air.

Abstract: A method of determining a drive signal provided to a light-emitting diode (LED). The method including sensing, via a first sensor, a first light intensity corresponding to a natural light in a room, sensing, via a second sensor, a second light intensity for a zone of the room, determining, via the controller, an expected light intensity, and determining, via the controller, whether the second light intensity exceeds the expected light intensity. The method further including, in response to determining that the second light intensity exceeds the expected light intensity, determining, via the controller, an artificial light intensity, determining, via the controller, the drive signal based on a desired light intensity for the zone of the room, the artificial light intensity, the first light intensity, and the second light intensity, and controlling, via the controller, the driver to provide the drive signal to the LED array.
