Optimization Design Method for Cabin Lighting Based on Downhill-Simplex Algorithm

The optimization design method in illumination has been studied deeply. The application of Downhill-Simplex optimization algorithm in cabin lighting is studied in this paper. A lighting optimization design program is compiled based on the cabin lighting configuration for civil aircraft. The optimization design program is verified by a cabin lighting design case, the aim of which is to maximize the illuminance uniformity on the working plane in cabin. The result reveals that the illuminance uniformity on the working plane before and after optimization is 0.5 and 0.8, respectively. This indicates the optimization method used in the cabin lighting case is reliable. The design method can be applied to the non-imaging optical design fields such as aircraft interior and exterior lighting, road lighting and projector illumination design.
