Abstract

Automated tools for the design of freeform illumination optics have enabled a new class of high-quality, high-efficiency luminaires for general lighting. Additive manufacturing takes this concept to the next level – allowing for completely custom luminaires to be designed and manufactured for very specific use cases. This paper looks at the optical designs created and manufactured for a Department of Energy project exploring the use of additive manufacturing for the lighting market. The subtle nuances of designing freeform optics for additive manufacturing as well as results of optical testing of material and surface quality will be discussed. Finally, comparisons will be provided between the simulated, as-designed optical performance and that of the measured parts.
