The goal of this project is the development and provision of a light-dosimeter as an enabler to be used by a broad research community in future studies. The device shall record the individual light exposure for relevant groups of people by tracking not only the amount of light over time, but also its composition. Users will have access to the raw data, which facilitates future customisation. Findings can be used to increase awareness of the influence of light in society, i.e. daylight and artificial light to support positive and to prevent negative developments. The project team consists of an interdisciplinary team from the Lucerne University of Applied Sciences and Arts and external experts combining knowledge in light and lighting, chronobiology, metrology, electronics and product design.
