Zusammenfassung:A flash light emitting diode (LED) package includes: a first substrate including first and second opposing surfaces; an LED device on the first surface of the first substrate and having a light emitting region; a shutter on the LED device, and configured to expose and cover the light emitting region; a second substrate on the second surface of the first substrate; and a shutter driving unit on the second substrate and configured to move the shutter. The shutter driving unit includes: a magnetic field forming unit configured to generate a magnetic field in response to application of a current, a power generation unit having a permanent magnet and configured to generate power and/or movement in response to the magnetic field, and a power transmission unit connected between the shutter and the power generation unit and configured to transmit the power and/or movement to move the shutter.
