LIGHT DIFFUSING POLYCARBONATE RESIN COMPOSITION, MOLDING AND COVER FOR LED ILLUMINATION

摘要

PROBLEM TO BE SOLVED: To provide a light diffusing polycarbonate resin composition which does not cause blue retina injury by LED illumination and lowers less in brightness, its molding and a cover for LED illumination free of problems of blue retina injury.SOLUTION: A polycarbonate resin composition comprises (A) 100 pts.mass of a polycarbonate resin and (B) 0.1-10 pts.mass of a light diffusing fine particle and has a total luminous flux retention with a thickness of 1 mm of 40% or higher and an exposure allowable time index of 30 or greater.
