ABSTRACT:
A lampholder in accordance with the invention can suitably be used for a low-pressure discharge lamp (a) which operates at a high frequency and which comprises an elongated, tubular discharge vessel (b), said lamp being provided with a pair of electrodes (c, c') for maintaining an electric discharge in the discharge vessel. The lampholder (0) has contacts (1, 1') for connecting a high-frequency power supply (4), said contacts being electrically connected to a first (2) and a second terminal (2') for connecting the lamp. The second terminal is further removed from the contacts than the first terminal. A compensation conductor (6) extending between the first (2) and the second terminal (2') is connected to said first terminal (2). This leads to a reduction of conducted interference.
