LIGHT SOURCE DRIVING DEVICE
First Claim
1. A light source driving device, configured to drive a light-emitting unit, the light source driving device comprises:
- a direct voltage source, coupled with the light-emitting unit and configured to provide a direct voltage;
a first capacitance unit, connected with the light-emitting unit in parallel; and
a switching current adjustment circuit, connected with the light-emitting unit in series, wherein 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.

Abstract
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.
