LIGHTING SYSTEM CONTROL DEVICE CHARGING SYSTEM AND METHOD

摘要

A lighting system control device charging system and method including a control device charged from a light source in a lighting system, including control photovoltaic cell (28) responsive to control light (46) from the light source and generating control charging power (44); a capacitor storing the control charging power (44) and generating control supply power (42); and a control microcontroller unit (MCU)/transceiver (24) powered by control supply power (42) and generating a communications signal (40) to the lighting system. The control microcontroller unit (MCU)/transceiver (24) monitors charge state of the capacitor and directs the lighting system to increase the control light (46) when the charge state is below a low charge setpoint.
