Embodiment 1
[0021] Embodiment 1: the present invention presses as figure 2 Implementation of the structure shown: it consists of a light source 1, a hemispherical reflector 2, a hemispherical reflector 3, and a square rod 6.
[0022] The light source 1 adopts a short arc lamp; the hemispherical reflector 2 and the hemispherical reflector 3 are realized by molding glass-ceramic materials, and the hemispherical reflector 2 and the hemispherical reflector 3 are coated with a wide-spectrum cooling The reflective film filters out the infrared and ultraviolet spectrum bands that are harmful to the projection display. The square rod 6 is realized by a hollow wide-spectrum high-reflection mirror or solid K9 glass.
Embodiment 2
[0023] Embodiment 2: the present invention presses as image 3 The shown structural implementation is composed of a light source 1 , a hemispherical reflector 2 , a semiellipsoidal reflector 3 , a square rod 6 and a semihyperboloid reflector 8 . The light source 1, the hemispherical reflector 2, the hemispherical reflector 3 and the square rod 6 can be the same as those in the first embodiment. The material of the semi-hyperboloid reflector 8 is realized by casting glass-ceramics.
