Abstract
A lamp driver for an LED lamp includes a voltage input port which is adapted to connect the lamp driver to a power source. A boost converter circuit is connected to the voltage input port. A voltage output port is adapted for connecting an LED to the lamp driver. A shutdown circuit provides a shutdown signal, which is connected to the voltage input port for detecting an input voltage of the voltage input port and is connected to the boost converter circuit for controlling at least one active component of the boost converter. The shutdown circuit is arranged to shut down the boost converter circuit when a shutdown voltage at the voltage input port is detected. During the shutdown of the boost converter circuit, the voltage output port still provides an operation voltage for the LED.
