More and more companies developing human centric lighting systems

By intuition most people feel more energized on a bright sunny day and many of us have experienced how, for example, our mood and level of alertness and performance has improved after a good night’s sleep, and all with good reason. Many of the recent scientific studies in this area have shown that exposure to sufficient light during the day is as important for human health and wellbeing, as regular exercise and good nutrition.
On the downside, scientists have also found that modern people are less and less exposed to the vital daylight as we spend as much as 90% of our time indoors. Keeping this in mind, and knowing that people are different and have different needs and preferences for light due to the individual human biological set up, modern indoor lighting solutions need to offer the ability to be controlled accordingly.
“At Lighten we focus on the scientifically proven benefits of light to the human circadian system. We have taken our human centric lighting system to a new level by developing and patenting a Personalized Intelligent Lighting Control System (in short PILCS), which is capable of providing optimized lighting scenarios to support individual needs and preferences in any given situation,” explains co-founder and Head of Product Development, Lighten Steen Pedersen.
“We have developed our system with a very unique person oriented focus because we believe the future of lighting control lies in the understanding and support of each users individual set of needs and preferences in contrast to the many “one-size-fits-all” solutions provided by the lighting industry in the past,” he said. “Our personalized lighting control system can help support individual visual and biological needs and is as relevant in private homes as on the job or in schools, nursing homes and hospitals etc,” he added.
People want lighting technology to be intelligent and intuitive, that is, it must learn from and adapt to the behavior of the user and adjusts accordingly. Most people like the idea and thought of being able to control and optimize their living environment, including light, but very few neither have the time nor the interest in having to adjust light settings manually all the time. As a result, the system needs to do it automatically, Steen Pedersen explains, referring to recent studies conducted in collaboration with the Danish Building Research Institute.
“By offering a complete lighting control eco-system that includes cloud connectivity and big data processing capabilities we can learn from our user behavior and thus optimize the system continuously. Lights effect on human health is a vast and complex scientific research area, and must be studied further by scientists in collaboration with the lighting industry to wholly understand how lighting systems can support modern living and improve human health and wellbeing,” says Steen Pedersen.
Lighten’s new intelligent lighting control system
Lighten has developed a new intelligent lighting control system that enables the end user to control luminaires and optimize his/her own local lighting environment (lighting zone) according to his/her personal profile (based on user data such as age, sex and chronotype), preferences and needs. It has a dynamic daylight setting and sensor technology. It is capable of learning the behavior of the user and can be controlled from a wireless device such as a Smartphone or a computer/tablet PC.
The system can sense and adjust the light according to light inputs from daylight and surrounding light sources in order to apply the optimal light setting for the user. The system adjusts the right timing and preferred intensity and colour temperature through personal user data.
