Abstract
In response to the simplistic circadian regulation mode and insufficient personalized matching in current intelligent healthy lighting systems, the work aims to develop a personalized adaptation scheme that translates user circadian characteristics into precise light environment interventions, thereby enhancing the health benefits of home lighting environments. Based on the correlation mechanism between photobiological effects and circadian rhythms, the core parameters of circadian light effects were systematically sorted out. Multi-source data were integrated, and four types of user circadian profiles were constructed through K-means clustering. A three-layer design strategy of "state perception-strategy formulation-light effect execution" was proposed, forming a differentiated light recipe mapping logic. Finally, parametric simulation and three-dimensional visualization analysis of a typical bedroom scene were conducted using Dialux evo software, and comparative verification was performed to assess the differences in lighting environment needs among different circadian groups as well as the adaptation capability of the proposed strategy. Simulation comparisons demonstrated that under the scenarios of morning awakening, daytime activity, and nighttime rest, key parameters such as core illuminance and correlated color temperature showed significant differences among different profiles and the strategy could effectively achieve dynamic matching between the light environment and user circadian characteristics. This study has developed an integrated personalized circadian light effect adaptation strategy that combines the photobiological theory with user profiles, and its differential adaptation capability for various circadian groups has been verified through digital simulation. The research provides a systematic design methodology and theoretical reference for the personalized development of intelligent healthy lighting products.
