A blower system is provided to identify easily an operating state thereof by turning on a light emitting diode by using current induced from rotation of rotatory wings. A plurality of rotatory wings(110) are rotated around a rotary shaft(140). A permanent magnet(150) is disposed at one side adjacent to the rotatory wings. A coil(130) is installed at the rotatory wings. A light emitting diode(120) is installed at the rotatory wings. A voltage is applied to the light emitting diode by using current induced from the coil. The permanent magnet is maintained in a fixed state though the rotary shaft and the coil are in a rotating state. The rotatory shaft is installed in an inside of a housing. The permanent magnet is installed in the housing and is disposed adjacently to the coil.
