gxr. Optical members, lighting cover and lighting equipment

摘要

To provide an optical member and a lighting cover for a light transmitting property and light diffusion property are in a relationship by the frame tradeoff can be compatible with good balance. A first functional layer 10 provided on one surface of transparent substrate 1, the formed second functional layer 20 is provided on the other surface of the transparent substrate 1, the light source the first functional layer 10 an optical member 3 used towards 2. Wherein the first functional layer 10 contains a first transparent resin 11 and the first particle 12. Difference in refractive index between the first particle 12 and the first transparent resin 11 is 0.07 or less greater than 0. It is formed in a concavo-convex shape by the light source 2 side surface of the first particle 12 of the first functional layer 10. The second functional layer 20 contains a second transparent resin 21 and the second particle 22. Difference in refractive index between the second transparent resin 21 and the second particle 22 is 0.10 to 0.25
