    摘要: A light source comprises a discharge lamp (LA), a bridge circuit for driving the discharge lamp and a reflector (RE). The bridge circuit comprises a capacitor (C1) coupled between a lamp connection terminal (T3, T4) and an input terminal of the bridge circuit (T1). EMI caused by the discharge lamp is suppressed by connecting a further capacitor (C2) between the lamp connection terminal and the reflector, so that a conductive path exists between the reflector and the bridge input terminal formed by both capacitors.
