FAN CONTROL METHOD AND PROJECTION APPARATUS USING THE SAME

摘要

A fan control method for a projection apparatus is provided. The method includes the following steps. When the lamp is switched from a working state to a power-off state, the fan device is enabled. When a temperature of the lamp is reduced to a first predetermined temperature, the fan device is disabled. When the temperature of the lamp is reduced to be lower than a second predetermined temperature, the fan device is enabled again. When the temperature of the lamp is reduced to a re-ignition temperature, the fan device is disabled.
