Method and device for driving a metal halide lamp |
| abstract |
A gas discharge lamp (2) is operated with an alternating current. A positive lamp current (Ip) is generated with a positive current intisity (Ip) for a positive duration (τp). A negative lamp current (IN) is genrated with a negative current intensity (IN) for a negative duration (τN). A duty cycle (D=τp/(τp + τN)) differs from 50%. A current ratio (R=Ip/IN) differs from 1. |
