Dynamic visible light
Visible-light output can vary in spectrum, color temperature, and intensity to reflect different times of day and application requirements.

Artificial Sunlight Lighting™A new platform for Indoor Health
Bring more of the biologically relevant qualities of sunlight indoors. Our technology coordinates tunable visible light with near-infrared radiation to approximate selected spectral, intensity, and temporal characteristics of natural sunlight.

Lighting as an environmental input
Beyond illumination
Indoor Health considers how conditions such as light, air, sound, temperature, and materials influence human comfort, daily rhythms, and wellbeing.
Light is one of the most important environmental inputs. Yet conventional indoor lighting primarily addresses visual requirements and energy efficiency, reproducing only a limited portion of the natural sunlight environment.
Artificial Sunlight Lighting™ introduces a broader approach: coordinated visible light and NIR designed for biologically informed indoor environments.
Indoor Health
What if lighting were designed not only for what the eye can see, but also for the environment the human body experiences?
The platform
More than tunable-white lighting
A controlled NIR layer extends advanced visible-light systems beyond conventional illumination.
Near-infrared radiation
Controlled NIR extends the indoor spectral environment beyond visible illumination. It is a significant component of sunlight but is largely absent from conventional LED lighting.
Coordinated control
Visible and NIR outputs can be independently controlled and coordinated according to defined sunlight profiles, schedules, or user requirements.
Design objectives
Created for healthier indoor environments
Artificial Sunlight Lighting™ enables partners to develop lighting solutions with a new value dimension beyond lumens, efficiency, and color temperature.
- Support visual comfort and appropriate daytime light exposure
- Provide time-varying light aligned with daily rhythms
- Introduce controlled NIR into the indoor spectral environment
- Enable measurable exposure and performance parameters
- Support future Indoor Health research and product development
