Claim of US Patent No. 10,117,315

1. A wireless lighting module comprising:at least one light emitting diode (LED) configured to output light in a first illumination state and a second illumination state different from the first illumination state;
a wireless transceiver;
a timing component;
an interface component configured to receive a lighting coordination input signal from a first disparate wireless lighting module and an environmental signal from an environmental sensor while the at least one LED is in the first illumination state, wherein the lighting coordination input signal received from the first disparate wireless lighting module is configured for use in controlling illumination of the wireless lighting module, and the environmental signal is indicative of a detected proximity of an object or a detected motion;
a battery configured to supply power to the at least one LED; and
a controller configured to:
change an illumination state of the at least one LED of the wireless lighting module from the first illumination state to the second illumination state and initiate timing by the timing component in response to a received environmental signal indicating a detected proximity of an object or a detected motion;
cause generation of a first illumination state control signal in response to the received environmental signal indicating a detected proximity of an object or a detected motion and cause transmission of the first illumination state control signal, via the wireless transceiver, to one or more disparate wireless lighting modules to change an illumination state of an LED of the one or more disparate wireless lighting modules from their first illumination state to their second illumination state;
change the illumination state of the at least one LED of the wireless lighting module from the second illumination state to the first illumination state after the timing component indicates that a predetermined time period has elapsed and during which no additional environmental signal is received indicating a detected proximity of an object or a detected motion;
wherein the first illumination state of the at least one LED is determined based on a combination of the second illumination state, the lighting coordination input signal, the environmental signal from the environmental sensor, and a setting for the timing component;
wherein the change of the illumination state of the at least one LED of the wireless lighting module from the second illumination state to the first illumination state is in accordance to a timing protocol corresponding to the setting for the timing component; and
wherein the timing protocol delays the change of the illumination state;
change the illumination state of the at least one LED of the wireless lighting module from the first illumination state to the second illumination state and initiate timing by the timing component in response to a received first lighting coordination input signal from the first disparate wireless lighting module;
change the illumination state of the at least one LED of the wireless lighting module from the second illumination state to the first illumination state after the timing component indicates that an elapsed amount of time has passed subsequent to the received first lighting coordination input signal from the first disparate wireless lighting module and during which no additional lighting coordination input signals are received;
wherein the first disparate wireless lighting module is included within the one or more disparate wireless lighting modules; and
wherein in the first illumination state, the at least one LED is powered off, and in the second illumination state, the at least one LED is powered on.
