Why does Human Centric
Lighting Matter?

Human Centric Lighting

What is human centric lighting?

Human Centric Lighting represents a new concept that focuses on designing light that's adapted to human needs by taking artificial light and transforming it to have the same benefits as natural light.

How does it work?

Human Centric Lighting aims at modifying the non-visual parameters of the light spectrum and the illuminance to create light combinations that can get as close as possible to natural light, in order to have the benefits of sunlight, reproduce the cycles of the sun, and therefore accommodate to our circadian rhythms.
A Step Back
Artificial Light
Before we could bring light to our lives, we had to adapt to the natural light cycle of the Sun. That is, a 24-hour cycle in which we have about 12 hours of light and 12 hours of darkness. This 24-hour cycle has become fundamental to regulate our biological rhythms.
In order to take advantage of the time we have when there is no sunlight and continue our daily activities, we have brought artificial light into our spaces: we use artificial light for work, leisure and entertainment.
However, exposure to artificial light at the wrong time, or not receiving enough light at the right time, can have negative effects on our health, in particular on our circadian rhythm, which deals with awake and sleep cycles, hormones production and mood.
Your Indoor Sun
Kumux Lighting
With conventional artificial light, we expose ourselves to inappropriate light, having the same type of light at all times. This can lead to a disruption of our circadian rhythms, which can have a negative impact on our sleep-wake cycles, meaning difficulty sleeping, feeling energised, and dealing with stress.
In order to not alter these cycles, it is recommended to have indoor spaces where electric lighting reproduces or imitates natural light, taking into special account light non-visual parameters, such as light wavelength and color. This is called Circadian Lighting: an artificial lighting system based on accurately reproducing sunlight in any given moment of the day.
Only "on" and "off" was yesterday. With Human Centric Lighting, the user experiences the right light at the right time at different times of the day and year. People notice the effect consciously or experience it unconsciously.
