Optimization of Luminous Intensity Distribution of Roadway Lighting Luminaire Based on Genetic Algorithm

Uniformity of overall and longitudinal (U_o, U_L) are two important items to evaluate roadway lighting quality. The fitness function incorporates two adaptive parameters in order to take both U_o and U_L into consideration as multi-objective function for genetic algorithm. Installation geometry is specified to build up direct connection between I-table and r-table to result in an optimal I-table for R3 road surface. It proves that the application of GA to optimize I-table is feasible in this paper.
