Abstract
A guiding device and a projector comprising the same are provided. The projector comprises a blower and a bulb. The blower is used for cooling the bulb. The guiding device is disposed between the blower and the bulb, and comprises a body and a flapper. The body of the guiding device is formed with a first outlet and a second outlet. The first outlet and the second outlet are adapted to guide the blower to form a first airflow and a second airflow, respectively. The flapper is disposed in the second outlet and moves along a direction of gravity to partially cover the second outlet to force the second airflow to flow towards a portion of the bulb away from the direction of gravity.
Claims16
A guiding device for use in a projector, the projector comprising a blower and a bulb, the blower being used for cooling the bulb, and the guiding device being disposed between the blower and the bulb, the guiding device comprising:
- a body, being formed with a first outlet and a second outlet for guiding the blower to produce a first airflow and a second airflow, respectively;
- and
- a flapper, being disposed in the second outlet, wherein the flapper moves along a gravity direction by use of gravity to partially cover the second outlet;
- wherein by using the flapper to partially cover the second outlet, the second airflow flows toward a portion of the bulb away from the gravity direction.
