What’s the definition of circadian lighting?

Light is an electromagnetic spectrum that is a necessary stimulus for our visual and non-visual systems. Human beings have a certain circadian rhythm, which is a 24-hour biological clock. To balance this rhythm, incorporating circadian light is important.

About circadian rhythm

Understanding the details of the circadian rhythm is important. This will help your perception of the definition of circadian lighting. Circadian lighting has a close connection with the hypothalamus of our brains. The circadian rhythm is essential in receiving signals from the eyes. It reports to the brain whether it is daytime or night. The hypothalamus controls melatonin secretion to correlate our body with darkness and light.

Definition of circadian lighting system

Today, many of us spend most of our time under electrical lights, irrespective of whether it’s day or night. This can impact the circadian rhythm of the body. To maintain this cycle, many homeowners and commercial property owners including care homes are availing of the many benefits of utilising circadian lighting systems. Researchers show that circadian lighting can influence the sleep, mood and engagement of human beings.

Circadian lighting tuning systems:

Circadian lighting comes with different intensities of tuning for improved stimulus. The electric lamps generally have a specific tuning. These emit a blue light. Circadian lighting can also be noticed in electrical lighting that has three tuning systems. These are discussed in detail below:

  •        Intensity tuning:

    This is the most popular and cost-effective circadian lighting tuning. These fixtures maintain a fixed correlated colour temperature. Through a dimming system, you can regulate the brightness of the light. This helps in correlating with the time of the day. The lights are automatically controlled according to the brightness of the surrounding environment.

  •        Stimulus tuning:

    This circadian lighting system mimics the spectrum of daylight. This system can be programmed to reduce the blue light wavelength during the day. The wavelength of the blue light can be controlled during the evening without even changing the Correlated Colour Temperature.

  •    Colour Tuning:

    This tuning system involves modification of the light intensity and the CCT. After changing the intensity, this system can follow the lighting cycle of day and night. You can adjust cooler CCTs to become more focused and attentive. Again, you can adjust the colour temperature when the sun is up.
