Circadian lighting

Energize, relax, and perform

 
Sunlight-inspired Indoor lighting gives you the energy you need to
live a good, comfortable life every day.
Circadian lighting from Signify brings the experience and benefits of natural sunlight indoors, supporting performance, comfort, and well-being in classrooms, workspaces, and healthcare facilities.
Light is essential for vision, and for experiencing and responding to the world around us. But did you know that light plays an important role in regulating sleep, moods, behavior, and performance, and mental health?
This is the circadian, or biological, function of light. Whether we’re aware of it or not, the light we take in throughout the day plays a key role in determining our physical and mental well-being.

For Mercedes-AMG PERONAS F1 Team champion George Russell and his performance coach Aleix Casanovas, light is the number one way to adjust circadian rhythms, overcome jet lag, and elevate performance.

Stepping out of biological darkness

 
With connected lighting and dimming controls, we can optimize the color of the light based on time of day to replicate the body's natural rhythms, helping to avoid disruptions to our circadian cycle.
On average, people spend more than 90% of their time indoors, and many students and office workers spend 36% of that time in a classroom or workplace. Patients in healthcare facilities and elderly people with limited mobility can spend up to 100% of their time indoo.
The light that you experience throughout the day affects your circadian cycle, through both visual and non-visual receptors in the eyes. You need different kinds and quantities of light throughout the day to sleep well and to feel well and perform at your best when you’re awake. Specifically, you need brighter, bluer light in the morning and dimmer light with less or no blue in it in the evenings.
Signify has been at the forefront of circadian lighting since the discovery of the third non-visual photoreceptor that governs human biological rhythms in the late 1990s. Circadian lighting from Signify is task adaptable and flexible depending on the needs of different people in different situations, from students in classrooms to patients and staff in healthcare environments to employees in professional workspaces. Circadian solutions from Signify offer the high quality, reliability, and design excellence which has been our hallmark for over 125 years.

Circadian lighting for offices, education, and healthcare

 

Our circadian lighting offerings focus on the biological, emotional, and visual aspects of light. Our holistic approach supports individuals in receiving the energy they need to thrive in their daily activities, maintain a regular sleep routine, and wake up feeling recharged.

Circadian lighting for offices

Recent global events have underscored the importance of employee health and well-being. By investing in circadian lighting, companies can create workspaces that energize and engage employees, leading to increased productivity and efficiency. Our lighting solutions are designed to not only enhance workplace comfort but also contribute to cost savings and improved business outcomes.
  • Add value to the workspace
  • Use evidence-based lighting recipes to maintain the highest standards of employee safety and well-being to amplify  engagement and satisfaction
  • Bring the experience of daylight indoors to boost the morale, productivity, and efficiency of your staff
  • Increase productivity—investing in circadian lighting can lead to energized and engaged employees, resulting in a productivity gain of 12%
  • Boost efficiency—As staff-related costs make up 90% of business costs, investing in workplace comfort can boost business efficiency
  • Get certified—Many organizations are eager to enhance workplace comfort to gain building standard certifications, which could result in higher rental income and lower vacancy rates

Circadian lighting for education

Signify circadian lighting solutions can support student and staff well-being by creating an ideal learning environment. Research has shown that smart lighting can increase reading speed, improve concentration, and reduce test errors, ultimately leading to improved academic performance and overall well-being for students and staff. By investing in circadian lighting, educational facilities can promote engagement, motivation, and mental health among students.
  • Increase reading speed, improve concentration, reduce errors, increase motivation, and improve mood, well-being, and mental health for all students, including those with special needs, by simulating natural daylight indoors

The science behind circadian lighting

Light produces obvious and profound visual effects in us. It also produces non-obvious but equally profound non-visual effects. There are receptors in the eyes, alongside the famous rods and cones, with a direct line to the region of the brain—the suprachiasmatic nucleus of the hypothalamus—that regulates the human circadian rhythm.
This third kind of receptor contains a photopigment known as melanopsin. Melanopsin has a lot to do with the functioning of “sleep hormones” like melatonin and tryptophan, as well as with cognitive and affective processes in general. Melanopsin is most sensitive to short wavelengths of visible light—that is to say, blue light. Not surprisingly, the amount and timing of the blue light we get during each 24-hour period has a lot to do with our circadian health.
Curiously, the eyes melanopsin receptors don’t work in tandem with the human visual system, but entirely independently. We know this because experiments have demonstrated the melanopic effects of light even on people who are completely blind.
