ABSTRACT:
A light guiding device (1) and in particular to a light guiding device that can be used for illumination, backlighting, signage or display purposes is described. The light guiding device (1) comprises a transparent base substrate (2), upon a first surface of which are mounted light sources (3), and a guide substrate (4) arranged so as to encapsulate the light sources (3) upon the first surface. In this way the guide substrate (4) provides a means for guiding light produced by the one or more light sources over the first surface. The incorporation of scattering structures (5) along with appropriate choice of the refractive indices of the various layers provides a highly flexible light guiding device that is typically less than 1 mm thick. The described light guiding device (1) provides particular application as a seven segment display.
