Summary
This paper proposes a chronobioengineering framework for designing circadian-supportive LED lighting systems in skilled nursing facilities, with a specific focus on Alzheimer's patients whose deteriorating circadian systems are further disrupted by 24/7 artificial lighting environments. A daylight-matching 2×2 retrofit LED luminaire is being developed and piloted at a Philadelphia-area nursing home, with caregiver- and administrator-informed protocols to evaluate its impact on dementia symptoms and quality of life.
Key Findings
- Hypothesis that circadian-synchronized LED lighting will alleviate dementia symptoms and improve quality of life for both residents and caregivers in skilled nursing facilities.
- Identifies aging and dementia as compounding factors that make inappropriate artificial lighting especially debilitating, framing this as a design problem requiring evidence-based intervention.
- Describes development of a 2×2 retrofit LED luminaire designed to mimic daylight cycles for installation in a skilled nursing facility as a pilot study — quantitative outcome data not yet reported at time of publication.
