摘要： An edge-lit illumination system comprising a light transmitting sheet (10) and a light source (13, 14); the light source (13, 14) being positioned in proximity to and adjacent to an edge of said light transmitting sheet (10), characterised in that at least one of the two opposing surfaces (11, 12) of said light transmitting sheet (10) carries markings such that said markings are disposed randomly within each of at least one nominal area of said at least one surface. If this novel surface treatment is disturbed or disrupted, for example by staining or abrasion, the disruption to the illumination of the system is less than would be expected.
