Human-Centric Lighting: Rare-Earth-Free Photoluminescent Materials for Correlated Color Temperature Tunable White LEDs
Summary:
This paper discusses the development of white light-emitting diodes (WLEDs) using photoluminescent organic materials as an alternative to rare-earth materials, with the aim of supporting human-centric lighting.
Categories
- Lighting Design Considerations: The paper discusses the design and development of WLEDs using photoluminescent organic materials, which can be tuned to specific requirements, offering a higher degree of freedom to choose the light output spectrum.
- Sleep and insomnia: The paper discusses the detrimental effects of artificial lighting on sleep and health, and the need for dynamic artificial lighting that mimics the solar cycle to avoid circadian disruption.
- Cognitive function and memory: The paper discusses the role of light in non-visual functions such as the regulation of the circadian system, which can impact cognitive function.
- Hormone regulation: The paper discusses the role of light in regulating the secretion of melatonin, a hormone that helps regulate sleep and is a marker of the circadian system.
- Well-being: The paper discusses the concept of human-centric lighting, which takes into account both the visual and non-visual effects of light, with the aim of preserving human health and well-being.
