Human Centric Lighting refers to how lighting can be used to support human health, well-being and performance through a combination of visual, emotional and biological benefits of lights. The circadian rhythm of the human body is associated with the natural cycle of light and darkness, and subconsciously informs the body to regulate the awakening and sleep patterns. Thus, dimming and changing color temperatures through light sources such as LEDs, can imitate appreciate level of sunlight throughout the day.

Sustainability and the human activity It's important to say, this is of course only a small part what should be taken into account in a light installation – the solution should still be energy efficient, flicker free and much more. Human Centric Lighting is said to affect and influence human circadian rhythm, enhance visual activity and increase productivity – while providing an LED solution that is energy efficient and sustainable.

Recent studies show that especially photosensitive retinal ganglion cells (ipRGC), have been shown to be affected by light – on the blue scale – up to 10000K. This is particularly noteworthy, as blue light suppresses Melatonin and encourages the production of Dopamine, Serotonin and Cortisol, which means that greater exposure to it during the day, can make us humans more alert and productive in the workplace.

This area is constantly being researched, so this is not a “how-to” but more inspiration on how Human Centric Lighting can be a part of a LED concept.
