An illumination module including a light emitting element, a wavelength conversion unit, a control unit, and a determining unit is provided. The light emitting element is capable of emitting an excitation light beam. The wavelength conversion unit is disposed on a transmission path of the excitation light beam for converting the excitation light beam into a color light beam. The control unit is connected to the wavelength conversion unit and capable of driving the wavelength conversion unit to rotate and to shift relative to the excitation light beam. The determining unit is electrically connected to the control unit. When the determining unit determines that a shifting condition is satisfied, the determining unit instructs the control unit to shift the wavelength conversion unit relative to the excitation light beam, so as to change the irradiation position of the excitation light beam on the wavelength conversion unit.

Illumination module having wavelength conversion unit, projection apparatus, and light source control method

An illuminating device adapted to a projecting apparatus including a lamp module, a power module, and a fan is provided. The lamp module is separately disposed in the projecting apparatus. The lamp module has a lamp, an igniting module and a plate. The igniting module is capable of generating a high voltage signal to drive the lamp. The plate is disposed between the lamp and the igniting module for shielding radiating heat generated by the lamp. The power module is capable of generating a low voltage signal transmitted to the igniting module through a low voltage power line. The igniting module transforms the low voltage signal into the high voltage signal to drive the lamp. The fan is disposed at a first side of the lamp for cooling the lamp.
