LIGHT FOR IMPROVED WORKING CONDITIONS
LUM CONNECT VTL
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.
LIGHT IN THE INTERACTION WITH HORMONES
Cortisol and melatonin levels of the body during a typical course of the day.
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.
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.
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.
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.

FOR INDUSTRIAL WORKPLACES AND SUPERVISOR'S OFFICES
Based on the recommendations of AT Kearney and the German Electrical and Electronic Manufacturers‘ Association (ZVEI), Waldmann proves with its study TAMETO VTL how biodynamic light can be used at industrial workplaces in the future. Using natural light, TAMETO VTL supports demanding manual tasks at assembly workplaces. The indirect light component is geared towards daylight and changes light colour (3,000 to 6,500 K) and light intensity according to a defined regulating curve period. The neutral light (4,000 K) in the direct light component can be continuously dimmed.
The supervisor's office receives biodynamic light easily either via a free-standing or a suspended luminaire in combination with the light management system LUM CONNECT VTL, thus ensuring an increased well-being. The luminaire simulates the natural light corresponding to the respective time of the day, without requiring connection to the building management. The user thus benefits from the positive effect of light inside the building in no time in accordance with the Plug & Light principle.
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.
