Phosphor-free white LED lamp rich in yellow-green spectrum

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

This study initiatively developed the phosphor-free LED lamp based on high-efficiency yellow LED, and explored the photo-biological effects of yellow-green spectrum. Analyzing multiple ocular physiological parameters, cortical functional connectivity, and melatonin secretions at various moments, the authors demonstrated the positive photo-biological effects of yellow-green-rich phosphor-free LED lamp. This study revealed the spectral regulation mechanism and the intrinsic mathematic model of human physiological response, applicable in the fields of health-oriented lighting and displays.
