<p>The present invention easily adjusts the quantity of irradiated light without changing the spectral distribution of light irradiated on an irradiated object. In this invention, a light shielding member (32) is disposed between a reflecting member that reflects light emitted from a xenon light source (2), and an opening plate (3b) disposed on the side in front of the reflection from the reflecting member (3a) that reflects light emitted from the xenon light source (2) and having light opening parts (31) formed thereon that extract the emitted light from the xenon light source (2). The light shielding member (32) functions as a light quantity adjusting member that adjusts the quantity of adjusted spectrum light emitted. The light shielding member (32) is secured across the opposing sides of the reflecting member (3a). The quantity of light emitted is adjusted according to the width of the light shielding member (32).</p> |
