摘要： A projecting system including a light source module, a flow-conducting member, and a blower is provided. The flow-conducting member includes a hollow body, and at least one part of the light source module is disposed in the body. The body has an inlet and an outlet. The blower is adjacent to the inlet and used for blowing a flow toward the inlet along a first direction. The flow will leave the outlet along a second direction different from the first direction. Utilizing the flow-conducting method and disposition for fans/blowers according to the invention, even if plural light sources are disposed adjacent to each other, the heat generated by the light sources can be effectively dissipated.

摘要： An optical sensing apparatus with anti-dust structure, for sensing a rotation device which has a rotation surface rotating along a rotation direction, includes a base, an optical sensor, and a stop block. The stop block is located beside the optical sensor and disposed with the optical sensor on the base in accordance with the order of the rotation direction. A distance between a stagnation surface of the stop block and the rotation surface is shorter than a distance between a sensing surface of the optical apparatus and the rotation surface. When an air flow passes between the stagnation surface and the rotation surface, dust within the air flow could be partially deposited on the stagnation surface so as to reduce the deposition amount of the dust on the sensing surface. A filter apparatus with the optical sensing apparatus and a projector with the filter apparatus are also disclosed.

摘要： A velocity-profile modifying device is located between a heat component and an air pouring apparatus. The air pouring apparatus pours the air into the heat component via an air moving track. The velocity-profile modifying device is set at the air moving track and is used for modifying a first velocity-profile of airflow by the air pouring apparatus to a second velocity-profile and further for making the air distribute evenly toward the heat component. By providing the velocity profile modifying device, a better distribution of the airflow toward the heat component and a stable temperature status of the heat component can be achieved.
