<P>PROBLEM TO BE SOLVED: To provide a lighting fixture capable of irradiating illumination light of high output and high uniformity without causing damage to an optical member. <P>SOLUTION: By arranging an infrared-cutting filter 13 on a light path of irradiation light from an HID lamp 12, heated light is prevented from entering from a light source unit 10 to a lens optical system unit 20. With this, heat damage due to overheating of the optical member is prevented even if an optical member like a light-shielding plate 22 for shielding unnecessary light is installed on the light path of the lens optical system unit 20. <P>COPYRIGHT: (C)2008,JPO&INPIT |
