Abstract

An illuminating optical system including a lamp light source and a reflecting mirror device. The lamp light source emits light. The reflecting mirror device having double reflecting mirror arrays formed in at least a portion thereof which at least partly adjust a divergent direction of light emitted from the lamp light source.

Claims

exact text as granted — not AI-modified
1 . An illuminating optical system comprising: 
 a lamp light source which emits light; and    a reflecting mirror device having double reflecting mirror arrays formed in at least a portion thereof which at least partly adjust a divergent direction of the light emitted from the lamp light source.    
   
   
       2 . The illuminating optical system of  claim 1 , wherein the reflecting mirror device includes first through fourth reflecting regions which are sequentially disposed along a rotational direction thereof, and the double reflecting mirror arrays are formed in the first and third reflecting regions or the second and fourth reflecting regions.  
   
   
       3 . The illuminating optical system of  claim 2 , wherein the reflecting mirror device adjusts a divergent direction of the light emitted from the lamp light source so that the light is converted into elliptical or near-elliptical light.  
   
   
       4 . The illuminating optical system of  claim 2 , wherein an angle of a mirror surface of the double reflecting mirror arrays is 45°.  
   
   
       5 . The illuminating optical system of  claim 1 , wherein the reflecting mirror device adjusts a divergent direction of the light emitted from the lamp light source so that the light is converted into elliptical or near-elliptical light.  
   
   
       6 . The illuminating optical system of  claim 5 , wherein an angle of a mirror surface of the double reflecting mirror arrays is 45°.  
   
   
       7 . The illuminating optical system of  claim 1 , wherein an angle of a mirror surface of the double reflecting mirror arrays is 45°.
