Gate voltage threshold turn off for maintaining voltage supply during standby mode of a lighting system

摘要

Provided is a lighting system that includes a plurality of lighting elements to emit light, a power supply to supply power, a lighting driver including a microcontroller and to output power to the plurality of lighting elements for operation thereof, a control system to transmit a control signal to the microcontroller to initiate a standby mode of the plurality of lighting elements, and a semiconductor device configured to receive voltage from the microcontroller, and selectively enable and disable a low power consumption mode of the lighting driver, to thereby maintain voltage for communication between the microcontroller and the control system during the standby mode.
