Human-Centric Lighting (HCL)

Human Centric Lighting is abbreviated as HCL and focuses on the effects of lighting on people. Light serves not only for visual orientation but can also, for example, evoke certain moods or influence a person’s state of mind. From well-being to concentration and performance, all the way to the hormonally regulated sleep-wake cycle, lighting has a far-reaching impact. The concept of Human Centric Lighting aims to tailor artificial light specifically to individual needs in order to achieve the best possible light quality tailored to each person. Circadian lighting, which is adapted to the daily rhythm of sunlight, is one component of the HCL approach. However, stimulating, relaxing, or emotional lighting settings are also possible to support human health and well-being. Human-Centric Lighting is particularly prevalent in smart lighting systems and the smart home sector, as these systems are the first to enable lighting that flexibly adapts to a person’s daily routine or mood. Only when lights can be easily and simply dimmed, have their color adjusted, and much more can the HCL concept be fully implemented. The development of Human-Centric Lighting is therefore still in full swing.
