  • Publication number: 20190182940
    Abstract: The present disclosure provides an intelligent lighting control system configured for automated lighting adjustments. A light control module of the lighting control system receives a signal, such as an alarm signal, from an electronic device, such as a mobile electronic device. The light control module is configured to cause a transmission of a quantity of electrical energy to a lighting circuit of a light fixture electrically connected to the lighting control module. The light control module causes a quantity of electrical energy to be transmitted to a lighting circuit at a particular time of day determined based on the alarm signal.

  • Patent number: 10143069
    Abstract: The present disclosure provides an intelligent lighting control system for automated lighting adjustments. The system includes a first light control module configured to cause a transmission of a first quantity of electrical energy to a first lighting circuit of a first light fixture electrically connected to the first lighting control module. The system transmits a control message from the first light control module to at least one second light control module configured to cause a transmission of a second quantity of electrical energy to at least one second lighting circuit of at least one second light fixture electrically connected to the at least one second lighting control module. The system changes a flow of electricity from the at least one second light control module to the at least one second lighting circuit based on the input received via the first light control module.

  • Patent number: 9967959
    Abstract: The present disclosure provides an intelligent lighting control system. The lighting control system includes a module housing, a graphical user interface coupled to the module housing and a switch control circuit positioned in the housing and including a processor. The processor is configured to modulate the flow of electrical energy to a lighting circuit via a dimmer circuit. The switch control circuit is electrically connected to the graphical user interface. The processor is also configured to identify a device identification address compare the identified device address with one or more registered identification addresses saved in a dataset. The processor is configured to catalogue a command received at the processor and at least one event parameter detected contemporaneously with receipt of the command, if the identified proximate device identification address corresponds to one of the one or more registered device identification addresses saved in the dataset.

  • Publication number: 20180070431
    Abstract: The present disclosure provides an intelligent lighting control system. A first light control module of a plurality of light control modules determines a time of day. Each light control module in the plurality of light control modules configured to cause a transmission of a quantity of electrical energy to a lighting circuit of a light fixture electrically connected to the respective lighting control module. Occupancy at the first light control module is detected after a specific time of day. The flow of electricity from one or more light control modules in the plurality of light control modules is changed to change the flow of electricity to the respective lighting circuits connected to the one or more light control modules to turn off the respective light fixture based on the occupancy detection the time of day.
