摘要
We describe how an evolution strategy is used to automate the design of luminaire reflectors, in particular, we outline a computer simulation, consisting of a 2-D optical reflector with point light source, which is implemented for this purpose. The reflector shape is modeled using a Bezier curve representation, and photometric distributions are calculated in the near, middle and far fields using a ray-tracing approach. The automation of the design process is achieved through the use of a novel evolution strategy, termed differential evolution. For the effective operation of differential evolution, a merit function specific to luminaire reflector design is presented. Finally, we describe our investigation into the validity of the evolution strategy approach to reflector design. Based on our results, we propose that the technique is not only valid but also feasible. (C) 1999 Society of Photo-Optical Instrumentation Engineers. [S0091-3286(99)01602-5].
