Paper Abstract

Modern illumination applications increasingly require adapted non-symmetric light distributions. Examples can be found in street lighting, architectural lighting, and also in more technical applications as automotive lighting. From an optical design aspect this leads to an increasing need for freeform lens design. Even though some design methods for freeform surfaces exist, the development of non-symmetric illumination solutions is still challenging. We investigated the applicability of the Cartesian oval method for the design and production of lenses with customized light distributions in Suprax glass. Of importance are both the manufacturability and the usability with extended LEDs. In the following paper we will show the basics and implementation of this method also using GPUs and discuss the pros and cons in the context of the usual requirements of illumination projects.
