Abstract: A control system for a vehicle parking area includes occupancy sensing devices, which may be associated with light fixtures. During a device commissioning mode, each device emits position signals and identifies signal characteristics of position signals received from proximate devices thereto. A central controller collects the position signals from the devices and generates a data set comprising identified locations for each device relative to predetermined baseline locations, based on the received position signals and the identified signal characteristics. The controller further maps the identified locations for each of the devices to specified locations in the parking area comprising the predetermined baseline locations. During a normal operating mode, the controller may generate signals directing drivers in the parking area to unoccupied parking spaces, and/or regulate a lighting state for light fixtures in the parking area based at least partly on detected occupancy states.

Abstract: An area lighting control system is provided for a light fixture and occupancy sensors. In a pairing mode, the occupancy sensors transmit messages with respective unique addresses to the light fixture, which identifies an associated sensor network. Upon lapsing of the pairing mode, an operating mode follows during which the sensors transmit output signals representative of occupancy in the area, and the light fixture regulates respective light sources based on an occupancy state determined according to output signals received from the associated network. The output signals are transmitted according to pseudo-random time intervals in order to reduce wireless transmission collisions, and only upon determining no occupancy in the defined area. When signals are received from all sensors in the network during a predetermined time period, the light fixture dims the light sources, whereas otherwise the light fixture operates the light sources at full lighting state.

Abstract: A lighting control system is provided with a communication method utilizing downstream current modulation. A primary controller is electrically coupled to a plurality of lighting devices via a mains power transmission network. Each of the respective lighting devices includes an occupancy sensor and is configured to provide full illumination when occupancy is detected in the associated area. The controller identifies occupancy by an increase in current on the mains lines, directs the other devices to fully illuminate, and activates a timer. Prior to lapsing of the timer, any of the devices may indicate continued occupancy by adjusting an operating current to a respective light source according to a predetermined pattern. Upon identifying the pattern, the controller generates control signals directing each of the other devices to remain fully illuminated, and resets the timer. The predetermined pattern may for example include amplitude modulation, threshold numbers of cycles, or both.

Abstract: A lighting control system for a light fixture has an ambient light sensor mounted therein. A switching circuit provides power for driving lighting sources. A controller receives signals from the light sensor and regulates switching frequencies based on desired lighting output level and the ambient light condition. An ambient lighting channel extends from the ambient light sensor to an aperture between outer and inner surfaces of the housing. The ambient lighting channel may include a fiber optic light pipe which extends from the aperture to surround the light sensor. The fiber optic light pipe may extend through the aperture from the ambient light sensor to an ambient light source external to the light fixture. The light sensor may mount on a shared PCB with respect to the lighting sources, such as an LED array, and transmit ambient lighting information to the controller via a feedback loop.

Abstract: A power line communication system communicates dimming levels to a lighting circuit over AC power lines. A power line controller generates control signals which are inserted on the AC power signal to the lighting circuit. A first series resonant circuit is coupled across the AC lines to bypass high frequency components from the control signals. A power line receiver receives the AC power signal and extracts the control signal to generate dimming level signals corresponding with the desired dimming level. To extract the control signal out of the AC power signal, the power line receiver has a resonant circuit connected in parallel with the AC power line and tuned to transmit the ballast control signal and to filter out the AC power signal. A dimming level sensing circuit then senses the signal pattern on the control signal and generates a dimming level signal corresponding to the desired dimming level.
