Today numerical simulation is a major tool in the design process of non imaging illumination sources. The numerical simulation is in use for different integration levels of light sources, where various numbers of design parameters exist. A variation of all available parameters leads to high amount of samples, which must be simulated and analysed. To reduce the number of variants, a statistical relevant number of samples are used. For this purpose the methods of DoE (Design of Experiments) are applied. In connection with computational methods, the simulation process itself could be automated. This leads to a very efficient design process for non imaging illumination systems. Main challenges are the parameter definition for the DoE, the design of the automated process, and a correct approximation of the achieved result. After solving of all challenges, an efficient system for the prediction of the technical parameters of new illumination is created. This paper describes the general problem of variant analyses and the achievements in automatic DoE studies for illumination systems. An outlook shows how this method could be beneficial in the design process of daylight systems.
