Patent number: 10291426Abstract: Location-Based Addressing (LBA) is a method of controlling and commissioning networked lighting devices. The lighting devices communicate over a wireless network using radio frequency communication protocols. The lighting devices are commissioned or grouped based on their 5 respective locations in a building floor plan or a building architecture. The lighting devices are commissioned to respond to radio frequency communications that correspond to their respective locations. This imposed location-based architecture reduces the amount of transmitted data required to control the lighting devices and, thus, reduces the radio bandwidth required to control the lighting devices. In other words, controlling devices “multicast” instructions and controlled devices “listen” for instructions and act only upon instructions that correspond to their respective location. Hand shaking or two-way communication between the controlling devices and the controlled devices is not required.Type: GrantFiled: June 11, 2018Date of Patent: May 14, 2019Assignee: The Watt Stopper, Inc.Inventors: Richard R.

Patent number: 10136501Abstract: A lighting control system includes a device controller containing control circuitry that is configured to control drive currents delivered to a plurality of light emitting diodes (LEDs) of a lighting device. The control circuitry generates commands to compensate for failed LEDs in the plurality of LEDs by controlling drive currents delivered to a group of LEDs so that the illuminance level of light detected by an illuminance sensor will not substantially change because of the failed LED, if the voltage across the group of LEDs is less than the threshold amount. The control circuitry also controls the plurality of LEDs in response to data received from a sensor configured to measure a characteristic value of light received from the lighting device, by controlling drive currents delivered to the LEDs if the detected characteristic value of light from the lighting device has moved above or below a threshold.Type: GrantFiled: July 27, 2016Date of Patent: November 20, 2018Assignee: Eaton Intelligent Power LimitedInventors: Joseph R.

Patent number: 10129957Abstract: An LED lifestyle lighting solution using microcontroller technology to control LED load for managing nighttime illumination is disclosed, wherein the nighttime illumination is divided into a first stage being a high power illumination for a preset time period and a second stage being an energy saving/security illumination. The time period of the first stage high power illumination is managed by a virtual timer which is programmable and dynamically variable according to a user's living habits and needs. The second stage energy saving illumination having four options is produced by adequate combinations of LED load dimming and motion sensor operation. The LED characterized by a limited working voltage range, namely, Vth<V<Vmax, makes the LED lifestyle lighting technology completely different from the technology of conventional lighting sources. The present invention provides possibility to choose among different working modes integrated in a single LED lighting device.Type: GrantFiled: April 20, 2018Date of Patent: November 13, 2018Assignee: VAXCEL INTERNATIONAL CO., LTD.Inventor: Chia-Teh Chen

Patent number: 10123403Abstract: A method includes retrieving a current lighting state of at least one luminaire. The lighting state includes light intensity of the at least one luminaire. The method also includes retrieving a sensor state of at least one sensor and determining a next selectable lighting state available for the at least one luminaire and an illumination adjustment for a user interface element of a lighting control device configured to control the luminaire. The determining of the next selectable lighting state available includes comparing the current lighting state and the sensor state to a set of intelligent backlighting rules, and based on the comparison, determining an indicator state corresponding to the illumination adjustment to the user interface element of the lighting control device. The illumination adjustment produces visible output to the user via the user interface element as a visible cue to guide the user to select the next lighting state.Type: GrantFiled: September 29, 2017Date of Patent: November 6, 2018Assignee: ABL IP HOLDING LLCInventors: Christopher Trickler, Richard Westrick, Jr., Mark Norton

Patent number: 10117298Abstract: Apparatus and associated methods relate to a curtain configured decorative lighting system. The curtain configuration of decorative light stings is obtained by using light-string distribution elements, each of which receives an input signal by a conductive lead. The input signal is indicative of a plurality of lighting commands. The light-string distribution element then provides an output signal to a tap connector, to which a decorative light string can be connected. The provided output signal is indicative of lighting commands corresponding to a plurality of lighting elements distributed along the decorative light string connected thereto. The plurality of lighting elements of the attached decorative light string each illuminate in response to one of the lighting commands indicated by the output signal. In some embodiments, the decorative light string provides to the tap connector a signal indicative of lighting commands that do not correspond to lighting elements of that decorative light string.Type: GrantFiled: April 30, 2018Date of Patent: October 30, 2018Assignee: Seasons 4, Inc.Inventors: Jason Loomis, Jared William Everline

Patent number: 9998296Abstract: Location-Based Addressing (LBA) is a method of controlling and commissioning networked lighting devices. The lighting devices communicate over a wireless network using radio frequency communication protocols. The lighting devices are commissioned or grouped based on their 5 respective locations in a building floor plan or a building architecture. The lighting devices are commissioned to respond to radio frequency communications that correspond to their respective locations. This imposed location-based architecture reduces the amount of transmitted data required to control the lighting devices and, thus, reduces the radio bandwidth required to control the lighting devices. In other words, controlling devices “multicast” instructions and controlled devices “listen” for instructions and act only upon instructions that correspond to their respective location. Hand shaking or two-way communication between the controlling devices and the controlled devices is not required.Type: GrantFiled: February 10, 2017Date of Patent: June 12, 2018Assignee: The Watt Stopper, Inc.Inventors: Richard R.
