Abstract: A lighting system includes a wake-up light source to emit a wake-up light beam and a plurality of luminaires located in a space. A respective luminaire includes an illumination light source to emit illumination lighting for the space, a light sensor to detect light, a wireless transceiver configured for wireless communication, and a memory. The respective luminaire further includes a processor coupled to the light sensor, the wireless transceiver, and the memory. The respective luminaire further includes wake-up programming in the memory. Execution of the wake-up programming by the processor causes the respective luminaire to: (a) detect a plurality of light measurements above a light threshold; (b) determine whether the plurality of light measurements are in accordance with a pattern; and (c) in response to determining the plurality of light measurements are in accordance with the pattern, enter a beaconing mode.

Abstract: A method for controlling a wireless lighting control network includes determining, by a first network device, whether a message is received from a control device during a first time interval; in response to determining that the message was not received, transmitting, by the first network device, a message to other network devices to determine whether another network device received the message from the control device; in response to determining, during a second time interval, that the first network device did not receive the message from the control device and did not receive an indication from another network device that the message from the control device was received, transmitting a message to the other network devices to indicate that the first network device is a substitute control device; and periodically transmitting messages to the other network devices indicating that the first network device is an active substitute control device.

Abstract: In response to determining that the line power source for a subset or all member devices of a lighting control group is interrupted, an emergency luminaire enters an emergency mode (EM) active state by controlling a light source, via a driver circuit, to continuously emit emergency illumination lighting. Upon entering the EM active state, the emergency luminaire transmits, via a wireless lighting control network, an EM active message to a lighting control group repeatedly at a predetermined time interval. Emergency luminaire receives, via the wireless lighting control network, an EM exit message from another member device indicating to exit the EM active state. In response to receiving the EM exit message from the other member device, the emergency luminaire exits the EM active state by controlling the light source, via the driver circuit, to discontinue emitting the emergency illumination lighting.
