An airflow-guiding device for a light source includes a cap and a guiding element. The cap has an airflow inlet, a through opening, an airflow outlet, a foundation, an annular side wall, and a cover. The foundation is connected to a reflector of the light source. The through opening is located at the foundation and corresponding to a light outlet of the reflector. The annular side wall where the airflow inlet is located is disposed on the foundation. The cover where the airflow outlet is located is disposed on the annular side wall and opposite to the foundation. The guiding element includes a guiding opening and an annular body. The annular body is rotatably disposed in the cap. The annular body where the guiding opening is located surrounds at least part of the through opening and forms a guiding tunnel together with the annular side wall in the cap.

Airflow-guiding device and projector

A lamp source module includes a holder having an air inlet and an air outlet, a gas discharge lamp having a lamp reflector assembled onto the holder and a burner disposed in the lamp reflector, a light cover assembled on the holder and surrounding the lamp reflector, a blower duct communicating with the air inlet and extending along the exterior of the lamp reflector to the bottom of the lamp reflector, and an airflow generator communicating with the blower duct and capable of providing a cooling airflow. The air inlet is capable of causing the cooling airflow to enter the blower duct. The blower duct is capable of directing the cooling airflow to the bottom of the lamp reflector to make the cooling airflow pass through a sandwiched space surrounded by the lamp reflector and the light cover and then discharge from the air outlet.
