Lighting as an infrastructure of care

Abstract

This integrative literature review addresses the relevance of illumination. Through the lens of infrastructures of care, it proposes three analysis categories: (a) "illumination, culture, and life in society" gather studies on cultural and social aspects involving lighting; (b) "access to lighting, technology, and sustainability" demonstrates how access to light and technologies needs discussion considering structural disparities, resource scarcity, and sustainability; (c) "illumination in healthcare" explores its influence on the environment and perception of users in care settings. These themes intersect and demand a transdisciplinary approach. Analyses suggest that lighting projects and systems can contribute to feelings of welcoming, well-being, and belonging, while ensuring good visibility for services and procedures, alongside controlling glare and reflectance. Expanding exploratory research in social and community settings through case studies and prototype implementation is recommended. There is room for additional research considering illumination as an infrastructure of care, focusing on access and the positive experience of users and citizens.
