Beschreibung
Zusammenfassung:	The invention discloses a light emitting device which comprises a frequency generating circuit and at least one light emitting module. The frequency generating circuit is used for generating a frequency control signal; and the light emitting module comprises a current supplying unit and a light emitting component. The current supplying unit is used for controlling a drive current on a path and comprises a drive current supply source and a switch component which are respectively positioned in the path. The drive current supply source is used for providing drive current. The switch component is coupled with the drive current supply source and the frequency generating circuit and is turned on or turned off according to the frequency control signal to control whether the path conducts the drive current or not. The light emitting component is positioned in the path, coupled with the current supplying unit and used for providing a light source according to the drive current.
