Case Study: An Applied Research for Circadian Lighting Design

  • Maurizio RossiEmail author
Part of the Research for Development book series (REDE)


This chapter presents a research conducted at the Laboratorio Luce of the Politecnico di Milano as part of an industrial research project. Research has focused on the creation of a human centric lighting for residential spaces of the elderly, focusing on both the lighting design and the lighting product design based on the new LED technologies. This study has started with a detailed analysis of the needs and problems of the elderly in relation to artificial lighting. With reference to this aspect, the characteristics of a correct lighting for the elderly have been outlined, and then translated into requirements to be applied to lighting design and lighting product design, eventually identifying technological solutions and defining guidelines, lighting programs and concepts.
