  • Patent number: 10750598
    Abstract: Lighting systems and methods for lighting fixture location mapping, for example, using a combination of photosensing readings and/or other sensors to identify a correct mapping. These systems and methods may be used to resolve ambiguities that could not be resolved using other processes, such an auto-commissioning method that identifies more than one possible mapping of the lighting fixtures to spatial locations. Such ambiguities are typically found in floor plans that are symmetrical. The systems and methods of the present invention record and utilize environmental profiles, such as ambient lighting levels and occupancy patterns, to match lighting fixtures to their respective spatial locations and provide resolution to ambiguities in an auto-commissioning method that identifies more than one possible mapping of the lighting fixtures to spatial locations.

  • Patent number: 10728984
    Abstract: A powering circuit for a diode light source includes an inductor charged through an on/off switch. The charging occurs during a charging cycle for a controllable amount of time when the on/off switch is closed. The energy of the charged inductor is used to power the semiconductor light source by opening the on/off switch. In such a driving configuration, the ringing is nearly constant and thus may be suppressed using an appropriately configured circuit.

    Abstract: Described herein is method for operating and controlling a network of lights comprising a plurality of lights arranged in a number of groups (A, B) using a short-distance network. Each light includes a control module (23, 28) for controlling its normal operation and for short-distance communication over the short-distance network with a designated group controller (23?, 28?, 31, 32) and other control modules within the group. Each designated group controller (23?, 28?, 31, 32) is also operable for long-distance communication with a central server and transmits its own specific information as a control module as well as information received from other control modules within the group. Information relevant to more than one group can quickly be exchanged between adjacent groups over a long-distance network via the group controller of the adjacent groups, by-passing the central server, or directly over the short-distance connection to a control module of an adjacent group.

  • Patent number: 10560835
    Abstract: Luminaires in a lighting system have mutually different addresses. A setting device includes a communication unit that transmits an address request signal at a first transmission power level and a control unit that determines whether a total number of the addresses transmitted from one or more of the luminaires in response to receiving the address request signal is within a target range. The control unit instructs the communication unit to transmit the address request signal at a transmission power level different from the first transmission power level when the total number of the addresses is outside the target range, and executes pairing of the one or more of the luminaires that responded to the address request signal with a wireless controller when the total number of the addresses is within the target range.

  • Patent number: 10542598
    Abstract: A lighting system comprises one or more luminaires for illuminating an environment, each luminaire comprising at least one lamp controllable to emit configurable illumination. A set of configuration data (20?) is retrieved from a memory, the set of configuration data for a group of one or more of the lamps in the lighting system, the set of configuration data defining an initial lighting scene for rendering by the group of lamps. It is detected when at least one of the lamps in the lighting system is emitting illumination that would disrupt the initial lighting scene and at least one characteristic of the disruptive illumination is determined. The set of configuration data is modified based on the determined characteristic to account for the disruptive illumination. One or more lamps of the group are controlled, via the control interface, to render a modified lighting scene defined by the modified set.
