    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.
