| Zusammenfassung: | A light source driving device configured to drive a light-emitting unit is provided. The light source driving device includes a direct voltage source, a first capacitance unit, and a switching current adjustment circuit. The direct voltage source is coupled with the light-emitting unit and supplies a direct voltage. The first capacitance unit and the light-emitting unit are connected in parallel, The switching current adjustment circuit and the light-emitting unit are connected in series. The switching current adjustment circuit is configured to bear a part of a voltage stress of the direct voltage source and is configured to switch the direct voltage. |
