The same cycle takes place every day in the human body. The internal clock determines sleeping and waking phases, but also heart frequency, blood pressure and mood – a rhythm of biological processes mainly controlled and supported by light. Hormones, especially cortisol and melatonin, are the most active ones. If the body lacks light as a timer or clock, the result can be chronic fatigue, sleep disorders or depressions.


VTL (Visual Timing Light) ensures motivating light in the office. Throughout the day. The innovative light management system brings the dynamics of natural daylight to the interior of the building and expands the emotional and ergonomic aspects of light quality. Biodynamic light (Human Centric Lighting) can provide lasting well-being of the employees at the workplace especially in offices with insufficient daylight and also during the winter months when the internal clock is barely synchronised with daylight.


The innovative light management system has been developed in close cooperation with Prof. Dr. med. Dipl. Ing. Herbert Plischke, professor for light and health at the University of Munich, Faculty for Applied Sciences and Mechatronics. A biologically effective luminaire equipped with VTL changes brightness and light colour, while adapting itself to natural daylight. The greatest effect is achieved by biodynamic light (Human Centric Lighting) if it is incident on the eye from an extensive light source (indirect lighting) and under the right angle of incidence (from the front and from above).






Light in the interaction with hormones

Cortisol and melatonin levels of the body during a typical course of the day.

Morning

Morning

The hormone cortisol is produced in the body in the morning. It stimulates the metabolism and programs the body for day mode. The first morning light suppresses the production of the sleep hormone melatonin. VTL supports the activity of the stress hormone cortisol at the beginning of office work by stimulating cold-tone light and high illuminance values.

Noon

Noon

The levels of cortisol decrease over the course of the day. However, good performance levels of the office workers are still maintained around midday. For VTL, this means that it continues providing mainly activating cold-tone light and high illuminance values.

Afternoon

Afternoon

In the afternoon, the production of cortisol in the body has already decreased significantly, with the active working phase approaching its end. The production of the sleep hormone is not yet required at this moment. VTL supports this transitional period by means of a neutral mixed light. The illuminance is gradually reduced.

Evening

Evening

The melatonin hormone makes workers tired and reduces the activity in favour of night sleep. With biodynamic light during the day, the melatonin level is correspondingly high during the night. The person sleeps well and is rested and productive the next day. VTL supports the transition to the rest phase through reduced brightness and relaxing warm tone light.

Additional information on biodynamic lighting (Human Centric Lighting)

The third dimension of light

It has long been known that light does more than just help one sees and create ambience in rooms. But scientific studies also show that the right light also has a positive effect on our well-being, biorhythm and health. We are referring to the third biological dimension of light – the Human Centric Lighting.


The inner clock

Although our biological rhythm of 24 hours is genetically programmed, it must be re-synchronized daily through daylight or artificial light which is similar to daylight. The hormones cortisol, melatonin and serotonin are primarily at play here. If the body lacks light as a timer or clock, the result can be chronic fatigue, sleep disorders or depressions.


Biologically effective light

The right amount is key. For artificial light to be biologically effective, certain parameters must be observed which nature reveals to us. In rooms, a sky of artificial light is created through a combination of direct and indirect sources of light. They homogeneously light up the upper wall section and the ceiling.


More light for a better quality of life at old age

An aging eye requires a much higher level of illuminance. Light enables the ability to move and the freedom to do what one wants as far as possible. Light that is shadow-free and low in glare has a positive impact on spatial perception.

Lack of orientation, insecurity and urge to move are typical for patients suffering from dementia. They are often in a state of semi-consciousness which is intensified even more due to insufficient light influences. Consequences of which are pathological restlessness, sleep problems through to complete reversal of day and night rhythm. A biodynamic lighting promotes biorhythm in a gentle and effective way.


Additional value in health and care

Light in the morning invigorates the spirit and facilitates activity. From middle of the day onwards the warm light supports the body and prepares it for the night. The day and night rhythm or the biorhythm has a lasting stabilizing effect. Some gerontologists view it even as an opportunity to reduce administration of sleep-inducing drugs.

Staff members report that the light is good for the soul and strains the eyes less. If the residents can move without fear and are active during the day, it also simplifies the work for the personnel.

The higher investment costs pay off: thanks to the very high light output of biodynamic luminaires, fewer luminaires are needed in comparison to the conventional room luminaires. In addition, the light management system also helps in saving energy.
