Human Centric Lighting

Human centric lighting (HCL) represents a holistic approach to lighting design that prioritizes the well-being and needs of individuals. Instead of focusing solely on illuminating spaces, human centric lighting embraces the dynamic nature of light and the changing needs of individuals throughout the day to maintain the sequential and phase-relation ordering of the various circadian rhythms to support well-being, performance and health of humans. Circadian rhythms are biological processes governed by the brain's interpretation of light. The pineal gland secretion of melatonin corresponds with the light/dark cycle and defines biological night. The suppression and secretion of melatonin with the presence and absence of bioactive blue light exert great control over the body's physiological and psychological processes. HCL systems incorporate features such as tunable white lighting, which allows for dynamic adjustments in light intensity and color temperature to mimic the natural changes in daylight, to reproduce the dynamics of natural daylight indoors. Tunable white LED lights are indeed smart lighting systems that can automate lighting based on various parameters such as time of day, occupancy, or user preferences.
