Title:
REFLECTIVE MATERIAL AND OPTICAL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/078147
Kind Code:
A1
Abstract:
Disclosed is a reflective material (10) which is made from light-transmitting material, which has a first face that is a face (triangular-ridge or polygonal-pyramid array face) formed by arranging inclined faces with no gaps therebetween, and which has a second face that is on the opposite side to the first face and is a planar face or a gently curved face that is close to planar. Furthermore, the reflective material (10) has a first-face shape and a refractive index such that, when light entering from the first face or the second face enters the opposing face directly or enters from the interior of the reflective material after repeated reflection within the reflective material, said light is always incident at an angle of incidence that is larger than the critical angle of total reflection. An extremely high optical Q value having no optical leakage can be presented by means of a structure in which a hollow internal space is surrounded by the reflective material (10).
