Circadian lighting
Light can have a huge impact on our wellbeing and can be used as a tool for a healthier everyday life.
Artificial lighting has long been known to deliver a monotonous light color. Circadian lighting, however, can deliver multiple shades of color and vary brightness throughout the day. With this type of lighting, the surrounding environment can experience a noticeably better working environment and increased well-being.
Lighting solutions
Circadian luminaires contain an LED plate programmed with a light cycle where the color temperature (K) simulates the natural color temperature of the sun over the course of a day. The color gradient runs from the warm color temperatures (1800K) simulating sunrise and flows to the light/blue (6500K) in the middle of the day and ends the evening by returning to the warm color temperatures (2000K) as sunset.
Circadian lighting has been shown to help staff deal with sleep deprivation, mood swings and headaches, and has helped people with dementia to calmer behavior, a better circadian rhythm and less confusion. In addition, circadian lighting has been shown to help patients recover faster and have a positive effect on depression.
The "Special Area for Brain Injury" in the Central Denmark Region, which offers day care, residential care and rehabilitation programs for brain injured people, uses circadian lighting from Lumega. The lighting interacts with the interior design to create a better atmosphere for the residents.
Evidence of impact
At a conference in Norway, Mark Rea, a professor of architecture and cognitive science, published a study on Human Centric Lighting. He highlights that people exposed to 254 lux through vertical illumination for at least two hours, ideally in the morning, will suppress the sleep hormone melatonin by 30%.
Several other recognized studies dating back to 2011 show exciting positive results for patients in healthcare and students in schools. Lumega has a number of articles and research results that can be highlighted and reviewed during specific installations, so together we can find the relevant ones for your project.

Project planning & documentation
Designing a professional circadian lighting system is complicated. There is a distinction between circadian lighting with color temperature adjustments and complex lighting systems such as RGBWWA. Here, red, green, blue, white, warm white and yellowish LEDs are combined to create the ultimate control of the spectral power distribution and thus a near-perfect circadian simulation.
Delivery of the complete system is always done in consultation with the consulting engineer or lighting designer on the project. At Lumega, we work according to the relevant standards in the field.
DS/EN 12464-1 and CIE 026/E:2018.
