A heat convection dissipater for an LED lamp, comprises a convection heat dissipating device for an LED lamp, a light emitting diode module having a plurality of light emitting diodes; a heat dissipating unit behind the light emitting diode module for dissipating heat from the light emitting diode module set; a housing having a plurality of air holes at a lateral side thereof; the housing being engaged to the heat dissipating unit so as to form an internal space; and a blade wheel combined to the housing. Heat from the light emitting diodes is transferred to the internal space through the heat dissipating unit; external air is guided into the internal space through the air holes so as to drive air originally in the internal space flows toward the blade wheel to push the blade wheel to rotate so as to circulate the air in the internal space.
