LEDMOTIVE focuses on the development of Spectrally-tuneable devices that have a huge influence on human health, mood and performance and also with the possibility of adapting the light spectrum to any specific need.
According to the World Health Organization (WHO), most people spend approximately 90% of their time living in indoor spaces. However, exposure to natural light has many health benefits: it facilitates nighttime rest, improves school performance and even significantly reduces the likelihood of mental illness at certain ages. For this, it is essential that the circadian rhythm (the biological clock that regulates the hours of sleep and wakefulness) is modified as little as possible. Experts in Chronobiology insist that certain type of light stimulates or inhibit the body’s production of melatonin. This hormone ensures that the biological clock is reset to zero every 24 hours and protects the body from inflammatory diseases and aging.
It is clear that the artificial lighting of interior spaces affects the production of melatonin and ends up modifying the sleep patterns of people who spend a lot of time in closed spaces.
Our idea is based on a family of products that includes: a light source capable of recording, process and playback any light spectral fingerprint in real-time, regardless of whether it is natural, artificial, or custom-made for a particular application. This system combines the light of 7 differentiated color channels to produce any spectrum of light within the visible range. This makes it possible to eliminate or modify the light that produces the most harmful effects (e.g. violet light) or to emphasize the light that provides the greatest benefits, depending on each correct moment and application. The daily solar pattern is not a simple change in light tonality (Correlated Color Temperature – CCT) but rather a complete and continuous evolution of the spectrum.
With LEDMOTIVE technology it is possible to configure a lighting sequence according to a 24-hour circadian cycle, which oscillates between the light spectrum of sunrise and sunset, reproducing the hourly variations of sunlight. In this way, the biological clock can be synchronized with artificial light, when there are reasons that prevent access to natural exposure.
The IP background necessary for the project is provided through a family of 10 patents (PCT/EP2011/050002 “Optoelectronic device, system, and method for obtaining an ambient light spectrum and modifying an emitted light” and PCT/ES2017/070041 “Controlling lighting devices”).
