Three-Dimensional Computer Modeling of Secondary Lens for Street LED Luminaire in AutoCAD

In the paper is proposed methodology for iterative three-dimensional computer modeling of secondary optical lenses for street LED luminaires by using of Photopia and AutoCAD software. The methodology allows achieving of various desired light distributions of the luminaires by iteratively modifying the three-dimensional shape of the secondary lens. The created three-dimensional models of optical lenses shown are tested by Monte Carlo raytracing photometric analysis. The results confirm the performance and the possibilities for application of the proposed methodology.
