HIGH LUMINANCE CONVERGING/DIFFUSING BODY

PROBLEM TO BE SOLVED: To provide a high luminance converging/diffusing body having a synergetic effect between converging action and diffusing action based on plane convex lenses and prism reflectors. SOLUTION: Many plane convex lenses 1a having the same shape are formed on the surface side of a plate body formed by a transparent resin or transparent glass material at fixed intervals. On the rear side of the plate body, the bottoms of the lenses 1a are uniformly projected by required length and many prism reflectors 1b are uniformly and integrally formed on the whole gap parts among respective projecting bottoms of the lenses 1a.
