Human Centric Lighting:Biologically effective lighting

Light has a great effect on us humans. Not only does it allow us to see. Light stimulates us, and influences our mood and activity level. 

Because our physiological response to light depends on the light’s characteristics such as intensity and colour temperature, the characteristics of the artificial light in our surroundings will be of significance if we spend a lot of time indoors. Human Centric Lighting solutions can support the human circadian rhythm, enhance concentration, prevent sleeping disorders and improve our overall wellbeing.

What is Human Centric Lighting?

Human Centric Lighting solutions in schools, offices and hospitals can benefit students, staff and patients through increased energy and motivation. For example, a cool white light with high intensity at the beginning of the workday can shift the sleep phase forward and help to reset back our biological clock. In countries with limited daylight during the winter, luminaires with adjustable colour temperatures can alleviate winter depression and other seasonal related ailments.

How does this work?

Our circadian rhythm is adapted to the sun. We are more awake and perform better during the day, while our body has its lowest performance at night when we are usually asleep.There are many things that affect the circadian rhythm, including the time period for sleeping, food consumption etc. But the most important external factor affecting the circadian rhythm is daylight, and specific parts of it in particular. The eye contains photoreceptor cells called ganglion cells. These are particularly sensitive to a specific wave-length that is found in blue light. When these cells are exposed to light with the correct wavelength, they send signals to our ’inner clock’ that, in turn, manages the excretion of the sleep hormone melatonin. Simply stated, you can say that the more cool white light you are exposed to, the more the need for sleep is displaced.

Better HSE in multiple Industries

Human Centric Lighting is based on principles that are applicable to all human beings, making it relevant in most industries. Glamox delivers HCL solutions to schools, healthcare institutions, offices and to offshore installations. 

In 2015 Glamox supplied Human Centric Lighting to all class rooms at Kongsgårdmoen school in Kongsberg Norway. Kongsgårdmoen was the first school in the world with Human Centric Lighting. Glamox has so far supplied Human Centric Lighting to more than 50 different projects in different segments. We also contribute regularly to different research projects. In 2017 we took part in another ground breaking project, ”first-in-the-world-project”, Østmarka psykiatric hospital. Based on new research on people with bipolar sufferings, the hospital has specified a special, blue-blocked light. The emitted colour is amber, or orange, and it is turned on in late evenings and at night only(1).  Studies show that by blocking blue wavelengths, manic symptoms are reduced. The patients’ daily rhythms also improve. In 2018, Glamox supplied a HCL solution to one of the first European banks to invest in such a solution. The bank, SpareBank1 Nord-Norge, which is located in the North of Norway, hope that the lighting scheme will increase their employees’ welfare.
