Application of Diffraction-based Optical Components in Advanced Lighting Systems

Original language description

In this paper novel approaches to optical beam shaping for lighting systems are presented. Application of various computer generated micro/nano-structured optical components is discussed. In contrast to conventional diffusers manufactured using grinding, sandblasting or etching techniques, the Nanoptiqs components can manage the light in a more complex way, they can create sharp edges, generate complex shapes of light distribution curves and maximalise efficiency of optical systems. Simultaneously, relief micro-structure of the elements is convenient for effective mass-replication and can be easily transferred to wide variety of substrates. Unique properties of Nanoptiqs components allow for new designs and light distributions which are presented in a form of newly developed lighting fixtures. Second part of this paper discusses optical elements with volume modulation of refractive index and their application in lighting systems. The nature of volume modulation can not only further increase efficiency of the products, but it also significantly improves resistance of the elements to environmental conditions. The volume micro-structure contained inside the material is also very resistant to scratches and other mechanical damages. Design and manufacturing of volume optical elements is discussed with regard to management of polychromatic light. A crucial factor for wider application of volume elements is mass-replication. A novel approach to effective mass-manufacturing is presented based on vacuum deposition technique with a surface precursor layer. Optical function of the volume element is demonstrated on a real lighting system.
