Abstract:
A gas-discharge lamp comprising:a power supply interconnectable to a load; an overvoltage-protection-and-ground-fault-interrupt (OVP/GFI) circuit interconnected with the power supply, the OVP/GFI circuit including an overvoltage-protection (OVP) sub-circuit that deactivates the power supply when an overvoltage condition is detected, and a ground-fault-interrupt (GFI) sub-circuit that deactivates the power supply when a ground-fault condition is detected; and wherein the OVP sub-circuit includes a voltage sensor, a storage device interconnected with the voltage sensor and a shut-down device interconnected with the storage device, and wherein the GFI sub-circuit includes a current sensor, the storage device and the shut-down device, the current sensor being interconnected with the storage device.
