Abstract

For a long time, lighting was seen only from the perspective of meeting illuminance requirements, energy efficiency, and visual comfort. With the discovery of intrinsically photosensitive retinal ganglion cells (ipRGCs), it has been proven that lighting influences the synchronization of the human circadian rhythm. This corresponds to the 24-hour period of light and darkness during which the body regulates its physiological and behavioral functions. Among the methods that can be used to quantify illuminance in the non-visible spectrum, the use of scaled-down models is included. This article seeks to validate the use of a developed scale model to represent the chosen room as a case study for melanopic illuminance. For this purpose, measurements were taken with a spectrophotometer in both a real environment and a scaled-down model with the same physical and reflectance characteristics. Subsequently, the melanopic and photopic illuminance results from both models were compared and their correlation was verified using R Commander software. The results showed a strong correlation between both models, exceeding 0.9. This highlights the potential use of scaled-down models for studying melanopic illuminance.
