| Zusammenfassung: | The invention provides a light-emitting diode driving device, comprising a first filter, a sound circuit, a rectifying circuit and a transformer, wherein the light-emitting diode driving device dims light of the light-emitting diode module by a light-dimming circuit. The sound circuit damages the resonance phenomenon generated by the light-dimming circuit and an element of an electromagnetic interference filter. Therefore, in the light-emitting diode driving device provided by the invention, the influence of the resonance phenomenon can be avoided under the condition that relevant parameters of the light-dimming circuit or an electromagnetic interference filter are not changed, and the problem of brightness flicker or unstable brightness when the light-dimming circuit dims light is solved. |
