FRONT COVER OF ILLUMINATION FIXTURE, AND ILLUMINATION FIXTURE

摘要

PROBLEM TO BE SOLVED: To provide the front cover of an illumination fixture capable of maintaining a high transmissivity over a long period, and superior in heat resistance, optical resistance, wear resistance, and chemical resistance or the like. SOLUTION: The front cover of the illumination fixture is formed by installing the surface layer on the surface of a base material. The surface layer is composed of a resin composite containing an acrylic resin having at least one of dimethyl siloxane group and perfluoroalkyl group. As for the surface layer, the total surface free energy is 30 mJ/m2or less, the surface free energy of a dispersion force component is 25 mJ/m2or less when divided into two components of a polarity force component and the dispersion force component, and a refractive index is smaller than that of the base material.
