Light as a wavelength:
perception, psycho-physiological well-being
and health
From the first research on the color of light and its psycho-
physiological influences on man that gave rise to the Metamorfosi
project, Artemide research has subsequently investigated with
"My White Light" the effects of white light on circadian rhythms
and perception, developing families of products with proprietary
technologies based on fluorescent sources. These studies
were then renewed in the light of new LED technologies with
Metamorfosi 2.0 and Artemide TW (tunable white) and in specific
functionalities, such as the "Circadian Cycle", incorporated in
the Artemide App for IoT management of products and lighting
scenarios.
Many last-generation product families incorporate TW and RGBW
technologies in order to assure an excellent quality of light in every
space, guaranteeing the highest visual and perceptive comfort.
Increasingly transversal and expressive product families, like the
Discovery, or with more technical and architectural performance,
like the A.24 and A.39, accompany users through the different
spaces and moments of life, supporting their lighting needs and
concurrently ensuring their psycho-physiological well-being by
using color or dynamic white light.
This feature was developed using patented software that controls
light based on the principles governing our circadian cycles.
Psychophysical wellbeing depends on complex "internal clock",
synchronized with the natural cycle of night and day through
natural stimuli such as sunlight and ambient temperature, affecting
hormonal responses and the sleep-wake cycle, both strongly
influenced by light. Building on geo-localisation and temporal
location, the Artemide App regulates the intensity variation and
colour temperature of artificial light to best suit these rhythms.
The

and

contextualisation are supplemented by behavioural models that
recognise three different types of representative lifestyles in order
to calibrate the lighting to the rhythm of the activities that each
person carries out. The modulation of light starts with a warm, soft
glow upon awakening which, to stimulate activity, gradually shifts
towards cooler tones throughout the morning, recreating a pause
with warm light towards the middle of the day, moving towards
a second peak of stimulation with cold light in the afternoon and
ultimately providing a more relaxing atmosphere towards the end
of the day.
In addition to this complex programming, the user is able to adjust
the range of temperature and intensity, as well as the duration
over which the light modulation moves. In this way, everyone can

achieve their lighting needs in a way that follows the course of
circadian cycles in relation to their daily life habits.
A comprehensive consideration of human well-being has
increasingly been broadened to the entire ecosystem. In 2010, for
instance, the RWB (Red-White-Blue) patent combined light that
promotes plant growth with correct perception for humans. The
research on "Spectral light" carried out in cooperation with Philip
Rham investigated the perception of all living beings.
Research into the effects of light on human well-being and the
environment has opened up important perspectives to help
people live more safely in spaces while protecting their health.
Well before the emergency dictated by Covid-19, Artemide's
scientific research focused on the study of the effects of light on
pathogenic microorganisms, leading in 2020 to the development
of INTEGRALIS® technology. INTEGRALIS® is a patented light
technology that combines and integrates the visible and invisible
spectral range in an innovative formula that can sanitize and
improve the environmental qualities of space. Selected frequencies
of visible light inhibit the development and growth of bacteria, fungi
and mold, and UV light deactivates pathogenic microorganisms.
INTEGRALIS® works on the concept of "dose", that is, it adapts
the intensity of the sanitizing action to the rhythm of permanence
and absence of people in the spaces, to the typology of the
environments and to the objective of the intervention.
Different methods of sanitization can be applied individually or
integrated with each other by combining technologies, power, time
and results.
In spaces where the presence of people is constant during the
day, but to be interrupted in the evening - such as offices or stores,
museums and educational spaces - it is possible to implement
sanitization at night with maximum intensity of radiation.
In that same space, during the day, it is possible to opt for a non-
offensive radiation to preserve the sanitization, thanks to the special
spectral component of the patented technology INTEGRALIS®.
Artemide's expertise and know-how also translate into customized
design solutions through dedicated consultations in order to give a
measured response to the needs of each space and rhythm of life.
