摘要： An air filter module adapted to be used with a projection module and disposed to cover an air vent of the projection module. The air filter module includes a filter component and a cleaning unit. The cleaning unit is disposed to cover the air vent and configured to drive the filter component to have a movement so as to remove the dust on the filter component according to a cleaning-start signal. A projection device adopting the air filter module is also provided.

摘要： A blower and a method for decreasing eddy noise are provided. The blower includes a fan frame, a fan wheel, at least one induction element and a coil. The fan frame has in inlet and an outlet. The fan wheel is disposed in the fan frame and has a wheel hub and a plurality of fan blades connected to periphery of the wheel hub. The induction elements are fixed to the corresponding fan blades, the coil is disposed on the fan frame for driving the at least one induction element, such that the fan blade corresponding to the induction element swing back and forth to generate a vibration sound, and the vibration sound is counteracted with eddy noise generated when the fan wheel rotates. Moreover, the method for decreasing eddy noise is also provided.

摘要： An illumination system disposed in a projection apparatus includes a solid-state light source group, a cooling module, and an ion fan. The cooling module is thermally coupled to the solid-state light source group. The cooling module is located on a path of a forced convection air generated by the ion fan. The projection apparatus avails prolonging a life time of the illumination system, and the ion fan does not have a magnetic shearing sound of a motor and a wind shearing sound of fan blades to avail reducing an operation noise of the illumination system.
