The string of LEDs is coupled in series with a first semiconductor switch, wherein the string of LEDs and the first semiconductor switch are coupled between a power supply node and ground. During a period when the lighting device is powering up after being initially provided power by a power supply, the system controller is configured to monitor a drive current through the first string of LEDs and modulate a control signal provided to the first semiconductor switch based on the drive current to prevent the drive current from exceeding a maximum allowable drive current value for the first string of LEDs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Over-voltage handling of lighting device","description":"The present disclosure relates to a lighting device that employs at least one string of LEDs as a lighting source.
