Light has a great influence on people. Not only does it allow us visual perception, but it can also stimulate us and affect our mood and activity levels. Since our physiological response to light depends on its intensity and spectral composition, the properties of the artificial light in our environment are of particular importance when we spend a lot of time indoors.

A modern solution for people who spend most of the day under artificial light is Human Centric Lighting, which fully embraces the positive effects that light can have on people.

Thanks to new insights into the biological effects of light and innovations in lighting technology, our high-quality led lights for factories have the ability to adjust the intensity and color of the emitted light and thus achieve positive effects on the human body.

New, smart, networked light management systems offer enormous opportunities for better control and a better user experience.

What is circadian lighting and why is it important?

Circadian lighting is an approach within Human Centric Lighting (HCL) in which changing the intensity and spectral composition of artificial light affects human biological functions, just as happens under the influence of daylight. It is also known as biologically active lighting due to new medical findings confirming its impact on the biological functioning of the human body.

The human biological rhythm is directly related to the alternation of day and night. The blue spectrum in high-intensity daylight stimulates the human body's activity and keeps it alert, while its absence in warm tones of evening light allows the production of the hormone melatonin, which relaxes and induces sleep.

Circadian lighting supports the natural biological rhythm of humans, prevents sleep disorders and thus has a positive effect on their health.

How light affects human circadian rhythms

Light is the basic external natural coordinator of the circadian rhythm. It is influenced by special receptors for bioactive blue light that are located in the eye. This influence is so strong that in people with severe eye injuries, the body clock can be disturbed, leading to sleep disturbances.

An example of the negative impact of light on the circadian rhythm is looking at the screens of cellphones or other devices before bedtime. Most people with a modern lifestyle need to surf social networks and news, reply to an email or a message before bedtime. However, this intense light, aimed directly at our face, sends the information to the eye that it is still day and keeps us awake long after we have ceased such activities.

Negative effects of conventional artificial light

Electric lighting has fundamentally changed people's lives since the first light bulbs. With this invention, the rhythm of the human day was changed significantly, i.e. people could lengthen their days. Nowadays humans spend almost 90% of their time indoors and are exposed to artificial light, while our ancestors a few hundred years ago spent the same amount of time outside in sunlight.

From getting up in the morning at work to strolling through the city in the evening or working the night shift, people are constantly exposed to Modular Office Luminaire. Digitization means that the majority of people spend more than 7 hours a day in front of the screen. The time spent under daylight has dropped drastically, increasing the risk of various diseases (depression, obesity, sleep and mood disorders) as well as some other more serious diseases.

Circadian lighting can help us live a more natural rhythm, even if we spend most of our time indoors.
