Human Centric Lighting and its effectiveness
Light is the source of well-being
Circadian-friendly lighting sequences through the course of the day
Light always has multifaceted effects, visually, emotionally and biologically.
Human Centric Lighting:
“Lighting specifically designed to produce a beneficial physiological and/or psychological effect upon humans.“
Human Centric Lighting (HCL) supports human health, well-being and performance through deterministic and holistic planning and implementation of the visual, emotional and, in particular, biological effects of light. The predominant focus of Human Centric Lighting is the needs of a human being of their living, leisure, and work environments. The interdisciplinary balance between the parameters of artificial lighting, natural daylight, architecture and technology creates the right light at the right time for each use.
Decades of research confirm the interplay between work surroundings and health
Light has a significant influence on our mood and ability to concentrate
Decades of research have shown that light has a significant influence on our mood and ability to concentrate – and one of most important aspects of good lighting is timing. Our brain regulates the circadian rhythm of the body based on “light signals” from our environment. The circadian rhythm controls our energy level, mood and sense of alertness or sleepiness. When our inner clock no longer functions synchronously with the time of the day we become agitated and our reactions slow down – we are less attentive and it becomes more difficult to concentrate.
Adapting light colour and intensity during the course of the day
To implement an adequate Human Centric Lighting solution in the survey Osram installed a time-controlled lighting system with a circadian-friendly light sequence, meaning the luminaires adapt their light colour and intensity during the course of the day. Several light sources were aligned onto the walls to create high vertical illuminance levels. Luminaires suspended from the ceiling in the open office area generate a pleasant indirect light component and avoid glare. In total, the luminous intensity was almost doubled.
A balanced internal clock
The principle: "Dynamic daylight supports humans in all areas."
An interview with Andreas Wojtysiak, OSRAM Innovation, and the OSRAM product managers Nicolai Heber and Peter Bach
"A biological impact is primarily achieved by utilizing the control phenomena of light that coordinate our bodily functions. These include day/night control or activating effects on the central nervous system. Due to evolution, our biological functions and processes are mainly based on our roots in Central Africa – meaning a rhythm with 12 hours of day and 12 hours of night. Our biological system, our internal clock, so to speak, has only partially adapted to life in our corner of the world, where the length of a day changes between summer and winter."Read the full interview here
More concentration and creativity
Human Centric Lighting coordinates the interplay of light, atmosphere and space to correspond to the well-being of people in particular surroundings. HCL has special importance for modern office environments because it places people at the centre.Download the brochure
More light, more productivity
Increased lighting intensity means people can work in a more concentrated way, tire less quickly, make fewer errors, and detect errors more precisely. And what makes life more pleasant for the individual, is more lucrative overall for the company.Download the brochure
