Abstract:
Systems and methods that provide improved control of addressable lighting fixtures. Individual lighting units have assigned schedules defining the power levels for the unit at various times of the day. Adjustments to a scheduled level for each unit may be made depending on predefined exceptions, ambient daylight, conservation commands, override instructions, and boost signals. Individual occupants of the building are associated with sets of individual lighting units. An override command received by the system and associated with a particular individual occupant is applied to the individual lighting units with which the individual occupant is associated.
Abstract:
The present disclosure provides systems and techniques for a lighting fixture with a motion sensor and an emergency battery test switch. The disclosure herein provides a lighting fixture for fitting within a ceiling, wall, or other surface. The lighting fixture includes a frame which forms the perimeter of the lighting fixture. The frame includes two endplates and two side bars, forming an outer frame of the lighting fixture. The frame further includes a device mounting bracket coupled between the two endplates, separating the outer frame into two frames. Each of the two frames houses a lightguide which is coupled to a light source. Each of the light guides are coupled with a back reflector. The motion sensor and emergency battery test switch can be coupled to the device mounting bracket or elsewhere on the frame.
Abstract:
A processor receives data associated with a device. On the basis of the data associated with the device, the processor modulates a light from the artificial light source at a rate imperceptible to a human eye while detectable by a light sensor device. The modulated light is representative of the data associated with the device. The modulated light is detected, demodulated, and decoded by the light sensor device to retrieve the data associated with the device. Further, the data associated with the device is presented by the light sensor device to a user. In addition, the light sensor device is configured to receive input data from the user and communicate the input data to the processor via a wireless link. The processor is configured to receive the input data from the light sensor device and effect a change in a characteristic of the device based on the received input data.
Abstract:
An electrical system that includes an enclosure and a power source located outside the enclosure and generating a first current. The electrical system can also include a transmitting inductor located within the enclosure and electrically connected to the power source, where the first current generated by the power source flows through the transmitting inductor. The electrical system can further include a receiving inductor positioned proximate to the transmitting inductor within the enclosure, where the first current flowing through the transmitting inductor induces a second current to flow through the receiving inductor. The electrical system can also include a device located within the enclosure and electrically connected to the receiving inductor, wherein the second current induced in the receiving conductor powers the device.
Abstract:
A component housing band includes a center portion that comprises an aperture extending through the center portion and a mounting structure disposed adjacent to the aperture. The mounting structure extends from a surface of the center portion in a direction that is substantially normal to the corresponding surface of the center portion. The mounting structure engages the ends of a notch in a lens and forms a cavity to house an electronic component. Further, the component housing band includes a first elongated arm portion and a second elongated arm portion integral with the center portion and extending away from opposite ends of the center portion in opposite directions, respectively. The ends of the first elongated arm portion and the second elongated arm portion that are away from the center portion and opposite to each other are adapted to engage with corresponding latch structures of the lens.
Abstract:
A luminaire can comprise two different types of light emitting diodes (“LEDs”), for example a chip-on-board light emitting diode (“LED”) and at least one discrete light emitting diode. The luminaire can have a normal mode of operation that utilizes utility power and an emergency mode of operation that utilizes battery power. The luminaire may transition from normal to emergency mode upon loss of the utility power. During normal operation, the luminaire can operate the chip-on-board light emitting diode using utility power. During emergency operation, the luminaire can operate the discrete light emitting diode using battery power, without operating the chip-on-board light emitting diode.
Abstract:
A connector can include a first shell having at least one first wall made of an electrically conductive material, where the at least one first wall forms a first cavity. The connector can also include an insert disposed within the first cavity. The connector can further include at least one connector pin disposed in and traversing the first shell. The connector can also include an electrically conductive face seal that abuts against a distal end of the insert within the first cavity, where the at least one connector pin traverses at least one first aperture in the electrically conductive face seal. The connector can further include at least one electrically insulating bushing disposed within the at least one first aperture in the electrically conductive face seal, where the at least one electrically insulating bushing is further disposed between the face seal and the at least one connector pin.
Abstract:
A lighting device includes a plurality of light emitting diodes (LEDs) configured to emit a light. The lighting device further includes a color controller configured to repeatedly assert and deactivate a control signal to control whether one or more LEDs of the plurality of LEDs are turned on or turned off. The color controller asserts the control signal for a first time period and deactivates the control signal for a second time period, where a color of the light emitted by the plurality of LEDs depends on the first time period and the second time period. The color controller changes the color of the light emitted by the plurality of LEDs by changing one or both of the first time period and the second time period.
Abstract:
A joiner system for a channel raceway includes a joiner body with first and second posts, and a joiner wall panel separate from the joiner body. The joiner wall panel connects to the joiner body between the first and second posts to form a wall between the first and second posts. First and second connecting projections extend outward from adjacent the respective first and second posts. The first and second connecting projections are spaced apart from one another and in generally opposing relationship with respect to one another. The joiner body has a snap-fit component on the lower side of a base of the joiner body. The snap-fit component mates in a snap-fit connection with a splice plate to interconnect the joiner body and at least two pieces of channel framing.
Abstract:
An airfield lighting system can comprise a control system, a constant current regulator, and a plurality of light fixtures. The control system can command the constant current regulator to output a current level transition sequence. One or more light fixtures of the plurality of light fixtures can detect the current level transition sequence and execute a command at the light fixture, such as actuating a heating element or adjusting the intensity of light emitted by a light source.
