A method includes the steps of obtaining distance measurements between a device and a number of lighting fixtures, processing the distance measurements to assign coordinates to each one of the lighting fixtures, and facilitating registration of the coordinates of a subset of the lighting fixtures to obtain registered coordinates for all of the lighting fixtures. The coordinates indicate a relative location of each one of the lighting fixtures with respect to one another. The registered coordinates indicate a location of each lighting fixture in a desired coordinate space. Accordingly, a location of a lighting fixture within a desired coordinate space can be easily obtained, which may enable significant additional functionality of the lighting fixture.

A lighting shower includes a body, a lighting device, a control module, and a hydraulic power generating device. The body has a first portion and a second portion facing opposite directions and includes an inlet tube and an outlet cover plate disposed on the second portion. The lighting device includes a transparent cover disposed on the first portion and a light-emitting element disposed in the transparent cover. The control module includes a storage battery and a controller electrically connected to the light-emitting element and adapted to control the light-emitting element to turn on or turn off. The water flows into a first chamber of the body from the inlet tube and through the hydraulic power generating device out from the outlet cover plate. The hydraulic power generating device is electrically connected to the control module to output an electrical energy to the storage battery for storage for providing an electricity required by the lighting device.

A lighting fixture includes a solid-state light source, communications circuitry, a memory, and processing circuitry. The memory stores common security credentials, wherein the common security credentials are pre-installed during a factory calibration process. The processing circuitry is coupled to the solid-state light source, the communications circuitry, and the memory. The processing circuitry is configured to cause the solid-state light source to provide a desired light output. Further, the processing circuitry is configured to join a common network using the common security credentials, wherein only devices with the common security credentials are permitted to join the network.

A frame is obtained from an image sensor. The frame may include a number of zones, each of which in turn includes a number of pixels. Each one of the pixels may be associated with a pixel value. A pixel change value for each one of the pixels in the frame may be determined based on an average pixel value of the pixel over a number of frames. The pixel change value for each pixel may then be normalized based on an average zone change value for the zone in which the pixel is located. The average zone change value may be based on the pixel change value for each one of the pixels in the zone. By using the average zone change value to normalize the pixel change value, an image frame may be analyzed in an efficient and fast manner.

A lighting device system includes light emitters where a battery powers the light emitters. A battery supplies the power for powering the light emitters and a driver is arranged to selectively power the light emitters to adjust an operating parameter of the at least one light emitter based on the charge status of the battery. The driver may be in communication with a GNSS receiver that provides geospatial information used to adjust the at least one parameter. The driver may power the light emitters according to a non-adaptive light level profile and an adaptive light level profile where the light emitters consume less energy when operated under the adaptive light level profile than when operated under the non-adaptive light level profile. A processing device operatively coupled to memory determines, based on a state of charge of the battery, which profile to run.

A lighting fixture includes a solid-state light source, a fixture common bus, a driver module, and a control module. The fixture common bus is configured to receive at least one functional module and provide an input signal from the at least one functional module to one or more other modules. The driver module is coupled to the fixture common bus and the solid-state light source, and is configured to receive a power supply signal and provide a drive signal to the solid-state light source based on a driver control signal. The control module is coupled to the fixture common bus and configured to provide the driver control signal via the fixture common bus based on the input signal from the at least one functional module.

A distributed energy storage system is provided for a total integrated network environment. The system includes: a power server platform; and solid state low voltage lighting panels. The power server provides functions to LED panel lighting. The server works an intelligent gateway between the lighting and a variety of power sources, including conventional grid power. A modular server cabinet provides a grid tie point. Each server element provides a plurality of PCB mounted RJ45 connectors for electrical connection with low voltage panel lighting through network patch cables. The cables terminate between the power server rack and a low voltage panel light to provide 24 VDC power.
