摘要

The voltage converter (1) has a transducer element for reducing a direct current (DC) input voltage. The transducer element includes a luminous element (2), a resistor and a Zener diode (3) connected in series with each other, where an anode of the Zener diode is connected with earth (4). Two parallel-connected LEDs form lighting units that are connected in series with each other. The luminous element is designed to illuminate a working area of a hand-held electrical tool.
