Light as the source of well-being

Circadian-friendly lighting

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.

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.

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.

"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."

The products: Scriptus luminaire range for Human Centric Lighting in offices


The Scriptus range of luminaires fulfils all functional and aesthetic standards for Human Centric Lighting. The separately controllable direct and indirect distribution light units guarantee users high levels of individuality for personal settings and maximum visual comfort. In addition to 3000K and 4000K light colours, versions with Tunable White (TW) are also available. Blue light distribution can be individually set across the course of the day via the separately controllable TW white component in the direct and indirect components.

The Scriptus series of LED luminaires convinces with a modern, progressive design and was distinguished with the coveted iF Design Award 2017.

The solution: Modern lighting that focuses on people

The right light makes work easier

The illumination of office spaces and office workstations designed according to the specific tasks and activities verifiably contributes to improved creativity and productivity. It is easier to concentrate in good visual conditions, and habitats and light atmospheres deemed to be pleasant also achieve a greater sense of well-being and motivation.

The minimum requirements for professional office lighting are regulated via clear normative stipulations. Europe for example uses the EN 12464-1 standard. Various quality criteria such as illuminance, uniformity, glare control and contrast sensitivity define the quality of light.
