Light reflecting device

Claim 1

A light reflective device comprising: a support member having a surface having a substantially constant roughtness defining dents within the range of 10 to 100 microns; a continuous light reflecting layer covering the support member surface and having a light reflecting outer surface coextensive with and formed in conformity with the contours of the underlying ueven dented surface of the support member, said light reflecting outer surface thus having a substantially constant roughess defining dents within the range of 10 to 100 microns; substantially transparent fine spherical glass beads having a high refractive index and spaced from the light reflecting surface by a distance approximately equal to the focal distance of the glass beads, the glass beads being sized to fit in dents of the light reflecting surface; and a resin layer covering the glass beads and light reflecting layer, said resin layer comprising a first layer portion and a second layer portion each having light transmitting properties and each comprising a synthetic resin, the first layer portion having a thickness approximately equal to the focal distance of the glass beads and covering the light reflecting layer, the glass beads being dispersed over the first layer portion whereby the glass beads are spaced from the light reflecting layer by a distance approximately equal to the focal distance of the glass beads, the second layer portion covering the first layer portion and the glass beads and forming an outer surface having projections and indentations substantially conforming to the contours of the glass beads.
