Experiments on inverse method to illumination by optimization technique - IMIbyOPTIM

The present work reports an experimental procedure designed to verify a particular solution for the distri-bution of artificial light sources. The inverse method to illumination by optimization technique, IMIbyOP-TIM, is applied to generate an uniform field of illumi-nation as a result of the free location of purely diffuse light sources. A reduced scale enclosure is build to measure the effectiveness of the method on indoor en-vironments. The illumination field is observed over a work plane placed parallel to the floor and measured by photovoltaic sensors. The results measured on the workbench are similar to the simulation case, since the overall average shows that the mean value is close to the unitary target, with a standard deviation less then 0.0065. The largest relative difference between the re-sults was 3.58%, while the lowest was 0.03%.
