Modern lighting systems include many features that were not previously available to facility operators and users. For example, lighting systems that include light emitting diode (LED) luminaires or other types of luminaires may offer features such as: controllable dimming; color selection and color tuning; adjustment of other characteristics of emitted light such as color temperature or Duv control of the shape and/or direction of emitted light beams; and pre-programmed scenes or customized scenes that incorporate a set of pre-programmed features.
In facilities such as theaters, concert venues, sports fields and stadiums, and even in commercial buildings, the lighting needs can change frequently depending on who is using the facility at any given time. For example, a venue may be used for a convention or business meeting during the day and a concert or social event in the evening. A sports field may be used for a football or soccer game at one time of day and a lacrosse team practice at another time of day. However, lighting systems do not easily adapt to the needs of each user and event. Instead, lighting systems are typically set in a “fully on” or “fully off” arrangement unless the facility is staffed with technicians who can manually change the lighting system scenarios in response to new users' needs.
This disclosure describes methods and systems for controlling the functionality of a network of one or more lighting devices.
In various scenarios, a lighting device control system for controlling one or more lighting devices is disclosed. The lighting device control system may include a gateway controller communicatively coupled with at least one lighting device. The gateway controller may include a processor and a memory device. The memory device may include programming instructions for causing the processor to: receive a signal indicating that a portable electronic device is in a proximate range of either the gateway controller or the at least one lighting device. The processor is further configured to, upon receiving the signal, receive a light operation request from the portable electronic device, wherein the light operation request comprises one or more settings for one or more optical characteristics of light that the at least one lighting device may emit,
In some embodiments, the light operation request also comprises a time, wherein the time comprises a numeric time or a duration. Optionally, the instructions to cause the at least one lighting device to emit light may include instructions to initiate or maintain the at least one lighting device in an on condition or a requested condition for a first time period, and then switch the at least one lighting device to an off condition or a default condition when the first time period expires. Optionally, before the first time period has expired, the system may receive a request to extend the first time period to an extended time, determine whether the portable electronic device is authorized to extend the first time period to the extended time, and in response to determining that the portable electronic device is authorized to extend the first time period to the extended time, cause the at least one lighting device to continue to emit light that exhibits the settings for the one or more optical characteristics through the extended time.
The one or more optical characteristics may include a brightness or dimming level, color temperature, color, Duv, beam shape, and/or beam direction.
Optionally, the one or more optical characteristics may include a scene in which settings for one or more optical characteristics of the emitted light change over time. The gateway controller may be configured to cause the at least one lighting device to emit light by initiating or maintaining the at least one lighting device in an on condition and then causing the settings for the one or more optical characteristics of the emitted light to change over time according to the scene.
In one or more embodiments, the gateway controller may also include a communication interface such as a short-range or near-field antenna. In such embodiments, the signal indicating that the portable electronic device is in a proximate range may be a signal that is directly received from a short-range or near field transmitter of the portable electronic device.
Alternatively and/or additionally, the gateway controller may include a communication interface such as an antenna that is communicatively connected to a wireless local area network. In such embodiments, the signal indicating that the portable electronic device is in a proximate range maybe a signal indicating that the portable electronic device is connected to the wireless local area network.
Optionally, the signal indicating that the portable electronic device is in a proximate range may be a signal received from a fixture controller of the at least one lighting device upon detecting that the portable electronic device is proximate to the at least one lighting device.
In some embodiments, the gateway controller may be configured to determine whether the portable electronic device is authorized to initiate the light operation request by transmitting an account identifier associated with the portable electronic device and data from the light operation request to a remote serve, and receiving a confirmation that the portable electronic device is authorized to submit the light operation request from the remote server. Additionally and/or alternatively, the gateway controller may be configured to determine whether the portable electronic device is authorized to initiate the light operation request by determining whether the light operation request includes a valid unlock token.
The lighting device control system may also include the portable electronic device. The portable electronic device may include a processor, a user interface, and a memory device containing programming instructions for a lighting system control application that is configured to cause the processor of the portable electronic device to: cause the user interface to output a plurality of candidate optical characteristics for the at least one lighting device and, for at least some of the candidate optical characteristics, a user-selectable setting. The portable electronic device may also receive, via the user interface, a selection of at least one of the candidate optical characteristics and an associated setting for each selected optical characteristics, generate the light operation request as data comprising each of the one or more selected optical characteristics and its associated setting and an account identifier, and transmit the light operation request to the gateway controller.
The lighting device control system may also include the portable electronic device. The portable electronic device may include a processor, a user interface, and a memory device containing programming instructions for a lighting system control application. The portable electronic device is configured to cause the user interface to output a plurality of candidate optical characteristics for the optical radiation source.
Furthermore, for each of the candidate optical characteristics, the user interface may output a user-selectable setting, and indicia of whether an account associated with the portable electronic device has unlocked an ability to adjust the user-selectable setting. The portable electronic device may receive, via the user interface, a request to unlock a user-selectable setting for which the ability to adjust is locked; transmit a command to charge the account an amount that is assigned to the user-selectable setting; upon receipt of verification that the account has been charged the amount, unlock the ability to adjust the user-selectable setting; receive, via the user interface, a value for the user-selectable setting; generate the light operation request to include the value for the user-selectable setting; and transmit the light operation request to the gateway controller.
In certain embodiments, the lighting system control application is further configured to cause the processor of the portable electronic device to: determine whether the at least one lighting device is in a proximate communication range of the portable electronic device, and transmit the light operation request to the gateway controller only in response to determining that the at least one lighting device is in a proximate communication range of the portable electronic device.
In certain embodiments, the lighting system control application is further configured to cause the processor of the portable electronic device to: determine whether the gateway controller is in a proximate communication range of the gateway controller, and transmit the light operation request to the gateway controller only in response to determining that the gateway controller is in a proximate communication range of the portable electronic device.
In some embodiments, the gateway controller may transmit the light operation request to a fixture controller associated with the at least one lighting device.

Short-range communication transceivers are devices that directly communicate with each other via relatively short distances on the order of 100 meters or less, or 10 meters or less. Examples of short-range transceivers include those that adhere to short-range communication protocols such as ZigBee®, Bluetooth®, and Bluetooth® Low Energy (BLE) transceivers, and/or via infrared (IR) light transceivers. NFC transceivers are ultra-short range transceivers that adhere to one or more standards for radio frequency communications that may be used when two devices are in close proximity, and may include hardware elements such as loop antennas that exchange information via electromagnetic induction. Protocols for implementation of NFC may comply with industry standards such as ISO/IEC 18092 or ISO/IEC 18000-3, published by the International Standards Organization. Typical ranges for near field communications are approximately 10 cm or less, although it may be 20 cm or less, 4 cm or less, or other ranges. By receiving a connection request via a short-range communication protocol or NFC protocol, the lighting device or gateway controller will thus detect that the mobile electronic device is proximate to the lighting device.
This detection 401 may occur, for example, by receiving a connection request from the portable electronic device via a short-range communication or NFC transceiver. Alternatively, the detection 401 may occur by receiving a connection request from the portable device via a known wireless local area network (WLAN), such as a Wi-Fi network that has a limited range and to which the lighting device is also communicatively connected. By receiving a connection request from a mobile electronic device that is communicatively connected to the same WLAN to which the lighting device controller is connected, the lighting device controller will thus detect that the mobile electronic device is proximate to the lighting device controller.
The lighting device controller will also receive, via the communication interface, a light operation request 402 from the portable electronic device. The light operation request will be one or more data packets that include one or more settings for one or more optical characteristics of light that the optical radiation source of the lighting device or devices that are associated with the lighting device controller and/or other communicatively connected lighting devices may emit. The one or more optical characteristics comprise may include settings such as a brightness or dimming level, color temperature, color, Duv, beam shape, and/or beam direction of the light emitted by the optical radiation source. The lighting device controller may determine whether the portable electronic device is authorized to cause the lighting device(s) to implement the light operation request 403. If the lighting device controller determines that the portable electronic device is authorized to initiate the light operation request, it will cause the optical radiation source(s) to emit light that exhibits the one or more optical characteristics of the light operation request 404. If the lighting device controller determines that the portable electronic device is not authorized to initiate the light operation request, it will not implement the request and thus not activate the optical radiation source(s) according to the request 405.
To determine whether the portable electronic device is authorized to cause the lighting device controller to implement the light operation request 403, the lighting device controller may determine whether the portable electronic device is associated with a valid unlock token for the light operation request. A valid unlock token is a digital identifier that the lighting device knows represents authorization to activate or change one or more characteristics of emitted light, such as a code or authentication token. The lighting device controller may receive the unlock token from the portable electronic device with the light operation request and compare the token with a set of locally or remotely stored authentication tokens to determine whether the received token matches a known valid token or adheres to a valid token standard. Alternatively, the lighting device controller may receive an account identifier for the portable electronic device, transmit the account identifier to a remote server so that the remote server can perform the authentication, and receive the unlock token from the remote server of the remote server determines that the portable electronic device is authorized to unlock the requested feature of the lighting device.
To obtain an unlock token, the user interface may output indicia of whether an account associated with the portable electronic device has unlocked an ability to adjust the user-selectable setting. The portable electronic device may receive, via the user interface, a request to unlock a user-selectable setting for which the ability to adjust is locked. If so, the portable electronic device may transmit a command to charge the account an amount that is assigned to the user-selectable setting. Upon receipt of verification that the account has been charged the amount, the portable electronic device may unlock the ability to adjust the user-selectable setting and generate or receive the unlock token.
To cause a lighting device's associated optical radiation source to emit light that exhibits the optical characteristics values of the light operation request 404, the fixture controller of that lighting device will implement one or more commands to control operation of the optical radiation source. Example methods for altering optical characteristics of LED lights are disclosed in, for example: (i) U.S. Pat. No. 9,188,307 to Casper et al., titled “High Intensity LED Illumination Device with Automated Sensor-Based Control”; (ii) U.S. Pat. No. 9,189,996 to Casper et al., titled “Selectable, Zone-Based Control for High Intensity LED Illumination System”; (iii) U.S. patent application Ser. No. 15/670,659, filed by Nolan et al. and titled “Lighting Device LED Module with Effects for Color Temperature Tuning and Color Tuning”; and (iv) U.S. patent application Ser. No. 15/670,671, filed by Nolan et al. and titled “Lighting Device LED Module with Effects for Beam Spread Tuning and Beam Shaping.” The disclosures of each of these patents and patent applications are fully incorporated into this document by reference. The optical characteristics may include a scene, which is a set of data corresponding to various optical characteristics of the emitted light for which the setting values will change over time. If so, then the fixture controller may cause the values of those optical characteristics of the emitted light to change over time according to the scene.
Optionally, the light operation request may include a time. The time is a data point indicative of a numeric start time, stop time and/or or a duration for activation of one or more characteristics of the optical radiation source. If so, then when causing the optical radiation source to emit light according to the requested characteristics the fixture controller will initiate or maintain the optical radiation source in an on condition according to the selected characteristics at a first time, and then when a time out condition occurs 406 corresponding to expiration (i.e., the off time or the end of the duration), the fixture controller will deactivate the optical radiation source and/or the selected characteristics when the time expires 409. Deactivation may include completely turning the light off, or returning the light to a default setting that does not include all of the selected characteristic values of the light operation request. Optionally, the system may receive an extension request 407 from the mobile electronic device before the time expires. The extension request will include a new (and later) stop time or an extension to the duration. If the fixture controller determines that the mobile electronic device is authorized to extend the time of operation according to the extension request (using authorization procedures such as those described above), the fixture controller will continue to activate the optical radiation source 408 with the requested characteristic values until the extended time expires, at which time the fixture controller will deactivate the light as described above.
Optionally, a light operation request may include a request to operate not only the lighting device that includes or is associated with the lighting device controller receives the request, but also one or more other lighting devices in a system that is communicatively connected to the lighting device controller that receives the request. For example, the light operation request may include one or more settings for one or more optical characteristics of light that a second lighting device may emit. To do this, the lighting operation request may include an identifier for the second lighting device, such as an address of the second lighting device, or it may include a general command such as “apply the light operation request to all connected lighting devices.” If so, the lighting device controller may determine whether the portable electronic device is also authorized to initiate the light operation request for the second lighting device, and if so the lighting device controller will transmit one or more settings from the light operation request to the second lighting device for a fixture controller of the second lighting device to use in operation of its optical radiation source. This transmission may occur via a wired or wireless communication link. The requested optical characteristics for the second lighting device may be the same as or different from those requested for the first lighting device.
Optionally, the user interface may include a scene selector 507 via which the user may select a scene that includes a set of one or more characteristics for one or more lights, in which the setting value for at least some of the characteristic(s) will change over time. The available values 517 may include pre-defined scenes, or the system may provide a scene creator user interface via which the user may select the settings, lighting devices and times that will define a new scene or adjust a pre-defined scene.
For any characteristic that is locked, the user may input (and the portable electronic device may receive via the user interface) an unlock request 603. If so, the system may generate and transmit a command to charge a user's account an amount required to unlock the setting 604. Upon receiving confirmation from the remote server that the account has been charged, the device may unlock 605 the characteristic so that the user can select the value of that characteristic's setting.
When the portable electronic device receives, via the user interface, a selection of at least one of the candidate optical characteristics and a value for an associated setting for each selected optical characteristic 611, it will generate a or otherwise identify light operation request 612 as data comprising each of the one or more selected optical characteristics and its associated setting's value and an account identifier. The portable electronic device will then transmit 613 the light operation request to the first lighting device via an NFC or short range communication protocol.
