SIGNBOARD BY REAR ILLUMINATION

摘要

PURPOSE: A signboard by a rear illumination is provided to easily standardize each of the elements of the signboard, thereby reducing the manufacturing time and cost of the signboard. CONSTITUTION: A signboard(12) by a rear illumination includes an optical conductive sheet(9), an opaque reflective layer, a contour and a light reflective layer. The opaque reflective layer is formed on one side of the optical conductive sheet(9) and the light reflective layer is formed on the other side of the optical conductive sheet(9). The contour is formed on the opaque reflective layer for displaying the contents transmitted by the sense of sight. The light reflective layer has a shape similar to that of the contour, and the light beam generated from the light source is transmitted to the display light reflective layer through the light conductive material for forming the highlight portion by reflecting the light formed around the light reflective layer.
