A power supply module is formed as a package body suitable to be assembled in a light emitting diode illumination apparatus. The power supply module includes a light emitting diode driver, a feedback control unit, a current converting unit, and a package material. The light emitting diode driver, the feedback control unit, and the current converting unit are packaged integrally by the package material. The current converting unit is suitable for supplying power to the light emitting diode driver and the feedback control unit. The feedback control unit is suitable to receive a feedback signal from a light source module disposed outside of the package body and provide an adjusting signal to the light emitting diode driver, so as to make the light emitting diode driver to adjust the magnitude of a control current and provide the control current to the light source module.
