摘要： A liquid crystal projector having a light source device which comprises a first reflective mirror surrounding a light source; a second reflective mirror which is disposed before the first mirror in the light emission direction and has a convergent shape with respect to the light source; a lamp house surrounding the light source, the first and second mirrors, and having an opening for cooling the light source positioned behind the first mirror; a first lamp shade disposed behind the light source and the first mirror, and having an area of an appropriate transverse cross section of a phantom cone or pyramid which is defined by a series of phantom linear lines connecting the light source and the contour of the opening for cooling the light source; and a second lamp shade disposed outside a curved wall of the first mirror and before the light source.
摘要翻译：一种液晶投影仪，具有光源装置，该光源装置包括围绕光源的第一反射镜; 第二反射镜，其在发光方向上设置在第一反射镜之前并且相对于光源具有会聚形状; 围绕光源的灯室，第一和第二反射镜，并具有用于冷却位于第一反射镜后面的光源的开口; 设置在光源和第一反射镜后面的第一灯罩，并且具有幻影锥体或金字塔的适当横截面的区域，该区域由连接光源和开口的轮廓的一系列幻影线性线限定用于冷却光源; 以及第二灯罩，其设置在所述第一反射镜的弯曲壁的外侧以及所述光源之前。
