Japanese Patent JP2004516618
Kind Code:

Abstract:
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.
