<P>PROBLEM TO BE SOLVED: To provide a lighting fixture that can irradiate an observation area with light in which its vector is weakened with reflection. <P>SOLUTION: An illumination attachment 6 includes a dome-shaped outer 10, a dome-shaped inner 12, and a front end reflective ring member 14 connected with a front end of the outer 10. A light reflection passage P is formed by the outer 10 and the inner 12, and light from a light source is scattered whenever the light is reflected with an inner face 10a of the outer 10 and an outer face 12b of the inner 12 at the process of passing through the light reflection passage P. The light emitted from the light reflection passage P enters into an internal deep part of the inner 12 by being reflected with an inner face 14a of the front end reflective ring member 14, and illuminates the observation area through an opening (outlet) 18 of the front end reflective ring member 14 by being scattered whenever it is reflected with the inner face of the inner 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
