An optical panel 11 comprises a plenum chamber 18 containing a mass of discrete optical particles M that are pressurised. The particle sizes can be uniform or vary. The pressurisation can be generated by loading imposed on the mass by the containment or, if the chamber is not completely filled thus defining a free surface, arise from the weight of the particles in the mass. The plenum walls 12-17 may be an acrylic material and the particles may be glass. The optical panel can be used to diffuse light for illumination with lights mounted along its edges, as a display panel, and may be part of a load bearing structure such as a floor or wall. |
