A Review Based on Oled Lighting Conditions and Human Circadian System

Abstract

Light is a form of energy that affects the human sleep cycle, working hours, alertness, productivity, and well-being. As one of the essential environmental factors, lighting requires extensive research to understand the human-environment interaction. Earlier studies reveal that various artificial lighting technologies are utilized to investigate the human circadian system; experiments employing solid-state lighting (SSL) sources are still being conducted to determine how the human circadian system is affected. Due to the advantages of OLED (organic light-emitting diode) lighting, there is a need to enhance this form of artificial lighting in an indoor environment. This paper focuses on a literature review on artificial lighting sources, particularly OLED lighting, used from the past to the present. This article also discusses how OLED lighting can influence the human circadian system in terms of different characteristics of lighting in an indoor environment. © 2023, Gruppo del Colore?
