Abstract:
1. A strobe light control circuit comprising: a light emitter; an insulated gate bipolar transistor (IGBT) device configured to turn on/off a current flowing in said light emitter, with said light emitter connected between an emitter and a collector of said IGBT device; and a drive circuit configured to apply a voltage signal for driving said IGBT device between said emitter and a gate of said IGBT device, wherein said IGBT device includes: an IGBT chip; a first emitter terminal configured to electrically connect said light emitter to an emitter electrode of said IGBT chip through a plurality of wire connections; and a second emitter terminal configured to connect said drive circuit to said emitter electrode of said IGBT chip, and said first emitter terminal and said second emitter terminal are individually and electrically-independently connected to said emitter electrode.
