Abstract:
A high-pressure discharge lamp having a base at one end andthe base (10) which has at least two electric terminals (j1, j2; j4, j5) for supplying voltage to the high-pressure discharge lamp,a discharge vessel (11) which is sealed at both ends and has a sealed end (11a) near the base and a sealed end (11b) remote from the base,an ionizable filling, which is enclosed in the discharge vessel (11), for producing a gas discharge,at least one radio interference suppression reactor (L1; L3) arranged in the base (10),at least two gas discharge electrodes (E1, E2) arranged inside the discharge vessel (11; 21), at least one first gas discharge electrode (E1) being connected to a first electric terminal (j1; j4) of the high-pressure discharge lamp via a return conductor (13) led out from the end (11b) remote from the base and via the at least one radio interference suppression reactor (L1; L3), and at least one second gas discharge electrode (E2) being connected to a second electric terminal (j2; j5) of the high-pressure discharge lamp by means of a supply lead (15) led out from the end (11a) near the base, anda starting device (Z; Z'), arranged in the base (10), for starting a gas discharge in the discharge vessel (11),wherein the return conductor (13) is connected to the second electric terminal (j2; j5) of the high-pressure discharge lamp via a bidirectional trigger (D; D') arranged in the base (10), and the first electric terminal (j1; j4) is connected to the second electric terminal (j2; j5) of the high-pressure discharge lamp via the at least one radio interference suppression reactor (L1; L3) and via the bidirectional trigger (D; D').
