Episode 6: Human Centric Lighting

What is Human Centric Lighting (HCL)?

At the beginning of the 21st century, researchers discovered a third photoreceptor in the human eye, which regulates our internal clock, controls the day-night rhythm, and influences our well-being – providing biological benefits. Human beings are at the centre of the lighting concept in HCL. Life is regulated by time and space. 365 days, 24 hours a day, day, night, seasons in different places – everything has a rhythm and a dynamic.

Human beings are at the centre of the lighting concept.

Thanks to this discovery, it became clear that artificial lighting needs to meet many more requirements than simply providing light. Lighting in the workplace should be designed and positioned to promote concentration whilst at home it should be pleasant and realized for relaxation. The biological effects of light cannot be ignored, that’s why designers and architects should remind about this when designing and planning lighting concepts. Thanks to Human Centric Lighting, light goes beyond illumination to make life better for all of us, bringing higher quality of life, performance, and well-being.
