Abstract
A lamp driver for an LED lamp is provided, comprising a voltage input port for connecting the lamp driver to a power source, a relay that is switchable between an energized state and a de-energized state according to a pick-up voltage, and a relay controller circuit that connects the relay to the voltage input port and that is switchable between a conducting state and an non-conducting state according to a threshold voltage, wherein the pick-up voltage is smaller than the threshold voltage.
