摘要： An edge lit illumination device is described. The device has at least one light source and a light transmission element having at least one light output surface and at least one light ingress edge substantially perpendicular to said surface. The light source is located adjacent to the light ingress edge so that light from the light source enters the transmission element via the said edge and propagates through the element. The light output surface is uniformly roughened across the output surface. The roughening is sufficiently fine to give an average Ra value across the surface of less than 1.0 mum/mm thickness of the element or drop-off of light output across the surface of less than 5000 lux.

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.

摘要： An edge lit illumination device is described. The device has at least one light source (13, 14) and a light transmission member (10) having at least one light output surface (12) and at lest one light ingress edge substantially perpendicular to the surface. The light source (13, 14) is located adjacent to the light ingress edge so that light from the light source (13, 14) enters the transmission element (10) via the ingress edge and propagates through the member. At least one light output surface (12) is uniformly roughened across its surface. The surface (11) of the said member opposite the output surface (12) has a pattern of light diffusing elements thereon. A method of producing a light transmission member for an illumination device is also described.
