    摘要: A backbox is disclosed herein. The backbox can include at least one wall forming a cavity, and a sensor mounting feature disposed on an outer surface of the at least one wall, where the sensor mounting feature is configured to couple to a sensor device. The backbox can also include at least one fixture coupling feature disposed on the at least one wall, where the at least one fixture coupling feature is configured to couple to a complementary coupling feature disposed on a housing of a light fixture. The at least one wall can be configured to extend substantially seamlessly from a portion of the light fixture at which the at least one complementary coupling feature is located.

    摘要: A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards a street is beneficial. The source can be coupled to an optic that comprises a cavity. At least a portion of the cavity can have an outline that is egg-shaped in cross section. A backside of the cavity (or a backside portion of the optic) can have an irregular shape for receiving the light emitting diode, for example to form a receptacle shaped to fit a circuit.

    摘要: A system for locating an asset can include a first visible light communication (VLC) device having a first controller, a first transceiver, and a first light source, where the first transceiver has a first range, where the first controller broadcasts, using the first transceiver, a first communication signal, where the first communication signal comprises an identification of the asset. The system can also include an asset communication device associated with the asset, where the asset communication device includes a second transceiver and a second controller, where the second transceiver has a second range, where the asset communication device is within the first range, where the second controller broadcasts, using the second transceiver, a second communication signal in response to the first communication signal, where the second communication signal comprises the identification of the asset.

    摘要: A luminaire mounting system can accommodate mounting a luminaire to different structures. The luminaire can comprise an adapter, which may be formed into or otherwise associated with a frame of the luminaire, for example. The adapter can provide a mechanical interface to different brackets that are configured for mounting to different structures. The adapter can connect to a first type of bracket that is configured for mounting to a vertically extending pole, to a second type of bracket that is configured for mounting to a horizontally extending pole, and to a third type of bracket that is configured for mounting to a wall or other flat surface.

    摘要: An actuator system for operating a switch is described herein. The actuator system can include a shaft of a handle assembly. The shaft couples to a handle and a male coupling element and has a number of positions. Further, a coupling body of a switch assembly can be positioned in the number of positions. The coupling body engages the switch and has a female coupling element, which has a slotted portion that receives the male coupling element and an angled terminus that aligns the shaft to a first position as the shaft couples to the coupling body. The slotted portion receives and engages the male coupling element when the shaft is coupled to the coupling body. The slotted portion prevents the male coupling element from disengaging when the coupling body is in a second position, and disengages the male coupling element when the coupling body is in the first position.

    摘要: A motion sensor includes a sensor element to sense a motion, and a controller communicably coupled to the sensor element. The controller is configured to set a detection sensitivity of the motion sensor to a maximum setting of the detection sensitivity. The controller is further configured to decrease the detection sensitivity of the motion sensor upon a detection of the motion until the motion is undetectable by the motion sensor at a decreased setting of the detection sensitivity. The controller is further configured to increase the detection sensitivity of the motion sensor until the motion sensor detects the motion at an increased setting of the detection sensitivity and to set the detection sensitivity of the motion sensor to a new setting based on the increased setting.
