Light is everything in nature. It provides growth, diversity and beauty. We humans are a part of nature. Light is therefore the most natural nourishment in the world for us. It determines our entire existence: Light affects important hormonal and metabolic processes, synchronizing our internal clocks again and again. Light gives our lives rhythm. Whenever there is a lack of natural daylight our rhythm is disrupted the VISUAL TIMING LIGHT (VTL) system from Derungs, also called Human Centric Lighting, recreates the effects of natural daylight, restoring proper rhythm and balance to people’s lives.

Light and people
Light controls a variety of internal clocks that regulate our day/night cycle and influence critical neurological and metabolic processes.

The third dimension of light
It is well known that the benefits of light go beyond just helping us see and creating a pleasant atmosphere within a space. Now, scientific research has shown that natural light also positively affects our biological health and well-being. These findings have created the third biological dimension of light.

The internal clock
Although our biological clocks are genetically preset to compensate for the 24-hour cycle, it must be re-synchronized daily through exposure to daylight or artificial light designed to replicate daylight. Hormone levels of Melatonin, Cortisol and Serotonin, all crucial elements in keeping our systems in balance. If exposure to daylight is missing, sleep disorders, chronic fatigue and/or depression may soon follow.

Biologically effective light
When trying to mimic the effects of natural light, the lighting system should follow similar parameters to nature. As in nature, the main illumination should originate from a large source area light. The combination of direct and indirect light sources produces an “artificial sky light”. Ideally, the wall and ceiling light blend smoothly, giving the environment a soft, natural feel.
