A proposal for a simplified model to evaluate the circadian effects of light sources

Links

Summary

This paper introduces a simplified model for assessing the circadian impact of light sources that approximates the accuracy of complex non-linear models while remaining practically accessible for lighting designers. The approach uses circadian efficiency functions and action factors, offering a more tractable alternative to sophisticated non-linear frameworks without significant loss of accuracy.

Key Findings

The simplified model produces results in good agreement with those from established non-linear circadian models, suggesting it can serve as a viable practical substitute.
The model accounts for the non-linear nature of human circadian response to light while maintaining ease of application, bridging the gap between simple linear sensitivity functions and complex non-linear approaches.
