Developing Dynamic Lighting Systems

  1. Bao Le, Aien Charity Grace White, Apoorv Chaudhari, Nafia AL-Mutawaly, Janette Elaine White, Wai-Keung Lee, Yeh-Liang Hsu, and Jonathon David White, "Dynamic white lighting to aid sleep and vision for persons living with dementia using off-the-shelf LED strips," Opt. Express 29, 38606-38614 (2021) (Note: There is an absence of papers designing actual systems. Experiments are using portable lamps or light boxes that can vary spectrum and intensity in a specific place. The idea is that in a home/institutional setting, the patient will primarily be in one place. This is not helpful for mobile patients.

Underlying Theory

Journal of pineal research 66, no. 4 (2019): e12562.(Note: Analysed many early results and showed that a particular color of light was responsible for suppression of melatonin in humans)
  2. Phillips, Andrew JK, Parisa Vidafar, Angus C. Burns, Elise M. McGlashan, Clare Anderson, Shantha MW Rajaratnam, Steven W. Lockley, and Sean W. Cain. "High sensitivity and interindividual variability in the response of the human circadian system to evening light." Proceedings of the National Academy of Sciences 116, no. 24 (2019): 12019-12024.(Note: Showed a hundredfold variation in the response to evening light between healthy individuals)
