The program realization of optic models for design of lighting devices

The article deals with the possibilities of three-dimensional modeling in the modern light device design. Light device’s optical system is used to distribute light. They have different construction, functionality, light curve types, and calculation methods. Light distribution defines purpose and class of light device. The optical calculation is based on tracing of light rays through light device’s optical system model. The calculation quality depends on the number of emitted rays. It’s necessary to trace (reflect, refract, absorb) each light ray over light device model. It is usually set by triangular meshes. However usage of the large number of small triangles slows the calculation process. Thereby a new optical system geometry model was developed. It allows to determine light device and provides fast and high-precision calculation using combination of usual triangular mesh model and simple shapes, i.e. planes, spheres, cones, torus, etc, or its parts. Also the algorithm to transform one model type to another is described. It is based on heuristic analysis of sequential shape imposition and uses the support vector machine. The developed model and algorithm can accelerate the calculation of complex light device several times.
