Abstract
A light source module adapted to a projector includes a light source, a light combining system, a first cooling fan, a second cooling fan, a first guide duct and a second guide duct. The light source includes a first light emitting device and a second light emitting device. The light combining system is disposed between the first light emitting device and the second light emitting device. The first cooling fan is disposed on the first light emitting device. The second cooling fan is disposed on the second light emitting device. The first guide duct is connected to the first cooling fan and guides a cooling airflow provided by the first cooling fan to the second light emitting device. The second guide duct is connected to the second cooling fan and guides a cooling airflow provided by the second cooling fan to the first light emitting device.
