Abstract
An air duct is secured in a projector. The air duct is configured to help a fan module to cool a light emitting module. The fan module defines an air vent. Each side of the light emitting module defines an opening. The air duct defines a hollow cavity. Two ends of the cavity respectively define an air inlet and an air outlet. The air inlet is aligned with the air vent and the air outlet is aligned with the opening. The airflow passes through the air vent and the air inlet to enter into the cavity. Then, the airflow passes through the air outlet and the opening to enter into the light emitting module. Finally, the airflow goes out from another opening to dissipate the heat of the light emitting module.
