Abstract
An apparatus operates at least one light-emitting diode in the form of a laser diode. The light-emitting diode is interconnected in series with the load section of a controllable semiconductor element and a current measuring resistor between a first supply voltage terminal and a second supply voltage terminal. The supply voltage terminals are the output connections of a voltage-regulating circuit in the form of a DC voltage boost converter which provides a supply voltage), and wherein a current-regulating circuit is provided for the current through the at least one light-emitting diode, whose actuator is the controllable semiconductor element.
