HUMAN CENTRIC LIGHTING
Everyone deserves adequate daylight from the fact that receiving sufficient light
supporting the natural circadian rhythm improves health, concentration, activity
level and hormone production of human beings.
Dynamic light – circadian rhythms is based on scientific research
studies in light and physiology. Both Danish and foreign results of
clinical- and other research studies are used in the dynamic lighting
program. The evidence shown in these research studies is evaluated
in order to improve the bad conditions when living in an artificial
indoor light.
As humans we are to be active in daylight and rest in the dark, the
light that we are active in consist of every colour in the colour spectrum, in the modern world it consist of 16.7 million colours. In dynamic light we use 16.7 million colours to formulate the right lighting
program to the specific purpose with focus on avoiding colours,
which are disturbing our physiology.
The light is automatically adjusted in a warm and soft light emission
within daytime creating a comfortable and pleasant atmosphere.
At night, the light adjusts and creates optimum lighting emission
necessary for the human body to relax and fall asleep. The light therefore requires no control or interference as it automatically adjusts
to the daily rhythm.
The light can also be turned on and off, e.g. if the patient whish

patient is not met with too high contrasts affecting the eye comfort.

IMPROVING HEALTH FACTORS
Receiving proper light at a daily basis can affect our health in a positive way
including, activity level, visual difficulties, pedagogical functions and risk of depression. Studies show that dynamic lighting solutions strengthen the immune
defence mechanism and rehabilitation.

THE CIRCADIAN RHYTHM
The circadian rhythm programmed in the lighting system illustrates the sunrise,
twilight and night-light. The rhythm is based on individual needs of patients
but could also take action from the availability of personnel in order to service
patients most efficiently.
Test installations in the health care sector show that simulating the circadian rhythm creates more
comfortable environments for patients and less stressful working conditions for personnel.
The simulation of the circadian rhythm is based on the biological rhythm of the human body as
illustrated in figure 1.1.

patients positively.
