Abstract (en)
[origin: WO0114790A1] A diffuse lighting arrangement, for example for backlighting an LCD display, comprises a two dimensional array of individual localised light sources, such as light emitting diodes (12) and at least one two dimensional grating (14) spaced in front of that array. A light diffusing plate or sheet (16) is preferably disposed in front of the diffraction grating (14).
