Abstract:
A cooling system for cooling down a heat source of a projection device is disclosed. The cooling system includes a fan, and a control module. The control module is configured for supplying a first voltage to the fan for a first duration after the projection device is powered off and a second voltage to the fan for a second duration successive to the first duration. The second voltage is greater than the first voltage.
