Abstract
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 cellresponsive to control lightfrom the light source and generating control charging power; a capacitor storing the control charging powerand generating control supply power; and a control microcontroller unit (MCU)/transceiverpowered by control supply powerand generating a communications signalto the lighting system. The control microcontroller unit (MCU)/transceivermonitors charge state of the capacitor and directs the lighting system to increase the control lightwhen the charge state is below a low charge setpoint.
