Artificial Sunlight Lighting™ technology
Visible light and NIR, coordinated as one system
A patented lighting platform designed to approximate selected spectral, intensity, and temporal characteristics of natural sunlight indoors.
Precise positioning
A practical approximation—not the entire solar spectrum
Artificial Sunlight Lighting™ does not claim to reproduce the full solar spectrum with laboratory precision. The platform focuses on controllable components that can be practically integrated into indoor lighting systems—particularly visible light and near-infrared radiation.
By coordinating these outputs over time, manufacturers can develop a broader and more biologically informed indoor light environment than conventional visible-only lighting provides.
Technology definition

The missing spectral layer
Why include NIR?
NIR is present in natural sunlight but is largely absent from conventional LED lighting. Because it is not visible to the human eye, conventional lighting standards and product specifications generally focus on visible photometric and colorimetric performance.
NIR interacts with skin and tissue differently from visible light and is increasingly studied for its potential physiological relevance. Artificial Sunlight Lighting™ introduces NIR as a controlled and measurable component of the indoor light environment.
The core technology does not depend on ultraviolet radiation. Any future UV implementation would require separate safety, regulatory, and application-specific assessment.
