摘要： A projector with air cleaning functionality is equipped with a negative ion generator. The negative ion generator is positioned along a cooling airflow route of the projector and is adjacent to a lamp module. A photo-catalyst sheet, which is stimulated by ultraviolet light emitted from the lamp module, can produce the negative ions quickly. The air, which is circulated along the cooling airflow route, carries the negative ions out of the projector so as to clean air in the surroundings.

摘要： A method and apparatus for adjusting cooling in a projection system, mainly comprises a fan, a louver installed at an air outlet and a sensor neighbor therewith. The fan is allowed to rotate to drive air at a predetermined rotational speed when the projection system is turned on, the louver is at a predetermined open rate at this time and the sensor is used to detect air temperature. When the air temperature is risen gradually beyond a predetermined temperature, the open rate of the louver is first increased gradually; and, when the air temperature is risen continuously and the open rate of the louver reaches its maximum, the rotational speed of the fan is then increased. When the air temperature is lowered down and the rotational speed of the fan is higher than a predetermined rotational speed, the rotational speed of the fan is first decreased gradually; and, when the air temperature is continuously lowered down and the rotational speed of the fan is decreased reaches its predetermined speed, the open rate of the louver is then decreased gradually. The louver is closed when the system is turned off. Therefore, an airflow resistance is decreased to increase a cooling efficiency so as to alleviate noise of fan by adjusting the open rate of the louver.
摘要翻译：一种用于调节投影系统中的冷却的方法和装置，主要包括风扇，安装在出风口的百叶窗和与其相邻的传感器。当投影系统打开时，允许风扇旋转以以预定的转速驱动空气，此时百叶窗处于预定的打开速率，并且传感器用于检测空气温度。当空气温度逐渐升高超过预定温度时，百叶窗的开放率首先逐渐增加; 并且当空气温度持续上升并且百叶窗的打开速度达到最大值时，风扇的转速随之增加。当空气温度降低并且风扇的转速高于预定转速时，风扇的转速首先逐渐降低; 并且当空气温度连续下降并且风扇的转速降低到达预定速度时，百叶窗的打开速率逐渐降低。当系统关闭时，百叶窗关闭。因此，降低气流阻力以提高冷却效率，从而通过调节百叶窗的开启率来减轻风扇的噪音。

摘要： The present invention provides a fan to generate airflow passing around a lamp reflector. A wake region is formed near a leeward surface of the lamp reflector, and a light cut is installed in the wake region. The light cut has a fixing end and is fixed on a side end surface of a lamp holder of the lamp by means of fastening bolts, the other end keeps a selected distance away from the lamp reflector and has a suitable distance along contours of the lamp reflector toward a rear end of the lamp reflector so as to prevent the light with high illumination going through the lamp reflector to the exhausting outlet for avoiding light leakage; hence, the exhausting outlet shall not be added inclined louvers and the windage is lowered down comparatively.
摘要翻译：本发明提供了一种用于产生通过灯反射器周围的气流的风扇。尾灯区域形成在灯反射器的背风表面附近，并且在尾流区域中安装有切割。光切割具有固定端，并且通过紧固螺栓固定在灯的灯座的侧端表面上，另一端保持与灯反射器相距一定距离，并且沿着灯的轮廓具有合适的距离反射器朝向灯反射器的后端，以防止具有高照明的光穿过灯反射器到排气出口，以避免光泄漏; 因此，排气出口不应该加入倾斜的百叶窗，并且风阻相对下降。
