【Abstract】 The calculation and design methods of a uniform plane light source obtained by a prismatic or cylindrical cavity having various cross sections and perfectly diffusing surfaces are proposed from the fundmental principal of light flux interreflection. The accuracy of this method has been justified by experiments which indicate that truncation errors can be confined to an acceptable level. The illuminance boxes designed and built according to this method have proved their uniformity up to 97%.更多还原
