At the end of a long day our
eyes often feel heavy and sore. A
constant feeling of sleepiness is
often followed by annoying bouts of
insomnia when we need to rest.
Research continues to shows the
correlation between natural light
and many aspects of individual
wellbeing.
However, modern society often
forces us into enclosed and
sometimes semi-dark spaces where
natural light is at a premium. Using
good artificial lighting that can take
the place of sunlight is therefore
becoming increasingly important.
In response to this evolution, in
recent years the lighting sector has
begun to assess not only the quality
of lighting appliances but also of
the light itself, switching its focus
from “how much light does it emit”
to “what kind of light does it emit”.
LED colour rendering, adjustability
and dimming are key to achieving
the visual comfort required to
ensure individual physical and
mental wellbeing.
The colour rendering metric is
defined by the CRI (Colour
Rendering Index) or, even better, the
TM30, which indicate how the main
colours are perceived by the human
eye. This is calculated using a scale
from 0 to 100 in which the higher
the value, the better the ability
to reproduce vivid and natural
colours.
A high CRI, which in Accento
products is always close to 100,
therefore helps to reduce eye
fatigue thanks to the improved
definition of the images.
Then there are the illuminance
and glare indices. Regulatory
specifications indicate the
illuminance and glare values
for various contexts, including
work and study spaces. But also
at home, where people require
maximum visual comfort in every
room we need light of the optimum
quantity and quality that does not
disturb our eyes.
Dimmable and highly adjustable,
our lamps can be tailored to the
needs of every individual.
