<p><P>PROBLEM TO BE SOLVED: To provide a reflection structure having a condensing angle causing minimal reflection light, and a minimal condensing area. <P>SOLUTION: This reflection structure 10 is used for reflecting a beam from a light source 10, and provided with a curved reflecting mirror 11, and a hemispherical reflecting mirror 15 for reflecting the beam emitted from the light source 13. The light source 13 is disposed at a point 12 that is the first focus of the reflecting mirror 11 and the spherical center of the reflecting mirror 15. Since the first focus of the reflecting mirror 11 and the spherical center of the reflecting mirror 15 are located at the same position, the beam emitted from the light source 13 positioned at the spherical center 12 of the reflecting mirror 15 is reflected by the reflecting mirror 15 and thereafter passes the spherical center 12 to reach the reflecting mirror 11, so that the entire beam emitted from the light source 13 is outputted from the reflecting mirror 11. <P>COPYRIGHT: (C)2004,JPO</p> |
