Abstract
The Lamp (La) is connected in series with first reactive impedances (C1, . To generate pulses, one or more second reactive impedances (C3, L3; C3-L2) are located as energy storage elements in series with one or more switch elements (S3, VTh1, VD1) to at least one of the first reactive impedances (C1, L1) and also in series with the high-pressure gas discharge lamp.
Claims2
An electrical circuit for pulsed operation of a high-pressure gas discharge lamp, in which the lamp (La) is in series with first reactive impedances,
- comprising
- a capacitor (C2) connected in parallel to the high-pressure gas discharge lamp, and a half-bridge circuit (S1, S2;
- VT1, VT2) connected to supply electrical energy to the lamp,
- wherein
- to generate pulses for pulsed operation, one or more second reactive impedances (C3, L2, L3) are located as energy storing means in series with one or more switch elements (S3), said switch elements and second reactive impedances being connected in parallel to at least one of the first reactive impedances (C1, L1) and, further, connected in series with the high-pressure gas discharge lamp (La).
