Human Centric Lighting
“Lighting specifically designed to produce a beneficial physiological and/or psychological effect upon humans.“
Light as the source of well-being
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.
"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
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.
CHRONOGY Eyewear – HCL light glasses that boost your life
Reduce Jetlag, increase performance, support well-being
The understanding of human centric lighting has improved rapidly within the last decade. This is due to the recent discovery of special photoreceptor cells in the eye. These cells that do not aid with sight, but instead help with controlling our body’s physiology.
CHRONOGY EYEWEAR are light treatment glasses that create supplemental lighting comparable to natural light from the sky, whenever and wherever you need it. The amount, timing and quality of light during day and night has substantial impact on our performance and health. Benefit from the latest advances in scientific research, and years of experience in lighting with personalized light treatment plans to support your health, well-being and performance.More information on CHRONOGY EYEWEAR
Greater concentration and creativity due to biologically effective light
Light impacts on how we feel and work. If it is biologically effective it can also have a stimulating or relaxing effect. Warm light with a higher red component has a relaxing effect. Light with larger blue components or higher colour temperatures are biologically activating. (This however must not be confused with damaging UV light contained in the spectral distribution of sunlight).
Compared to warm light, light with a distinct blue component more easily impacts the activating centres of our brain and the control centre for our inner clock. In this way it increases alertness, attention and the ability to concentrate. The biological effect is strongest when light is emitted from a wide-area source and from above, as with sunlight.
