摘要： A method for shutting off a projector having a fan and a light source is provided. The method includes the following steps. The power of the light source is reduced from a first power to a second power and the speed of the fan is increased from a first speed to a second speed after the projector receiving a first command. Then, a process is executed for shutting off the light source and the fan after the projector receiving a second command. The above-mentioned method is capable of not only preventing the projector from damage result from over-shooting, but also shortening the time needed to shut off the projector.

摘要： A cooling system for a projector is provided and disposed in the projector. When a sensing temperature of the projector sensed by a thermal sensor of the cooling system is higher than a maximum temperature, a control module controls a fan to increase a rotation speed. When the sensing temperature of the projector sensed by the thermal sensor is lower than a minimum temperature, the control module controls the fan to decrease the rotation speed. As a result, the temperature of the projector is maintained within a proper range.

摘要： A light source module comprises a case, a light source, a first air-circulation device, a second air-circulation device and an airflow guide. The case has an airflow outlet, and other components are disposed therein. The airflow guider includes a first stream-guiding part and a second stream-guiding part connected thereto. The first stream-guiding part and the airflow outlet are at a same side of the light source, the second stream-guiding part is over the light source. The first airflow provided by the first air-circulation device passes past the light source, arrives at the first stream-guiding part, flows from the front of the light source towards the back of the light source guided by the second stream-guiding part, and mixes up with the second airflow provided by the second air-circulation device and finally exits from the airflow outlet. Therefore, concentrated heat is prevented at the airflow outlet.

摘要： A partition installed in a housing of a projection apparatus to form a double-layer structure of a first zone and a second zone is used for a component of a cooling structure for the projection apparatus. Moreover, a first air inlet is disposed at the lower part of the first zone and a second air inlet is disposed between the first and the second zones. An air outlet with a duct and a plurality of sound sources and heat elements are disposed in the second zone. Outside air is drawn in from the first air inlet through a fan, then turned to enter the second zone through the second air inlet to cool heat elements and finally exhausted out of the system from the air outlet through the duct. Besides, the installments of the partition and the duct allow the distance of the sound source broadcasting to be lengthened and the diffusion light to be blocked so that both the noise and the leaking of the diffusion light can be reduced effectively.
