Human-Centric Lighting (HCL), which aligns artificial light with natural circadian rhythms to support well-being and productivity, is maturing beyond standalone applications. The latest trend is its deep integration into holistic smart building and smart city ecosystems. HCL systems are now leveraging IoT connectivity and advanced sensors to dynamically adjust color temperature and intensity based on real-time data, such as time of day, occupancy, and even individual user preferences via smartphone apps. In workplaces, these systems are linked to booking platforms to personalize the lighting environment for each meeting or focused work session. In healthcare, HCL is being integrated with patient management systems to aid recovery. In urban environments, intelligent street lighting networks adapt to pedestrian traffic and weather conditions while collecting environmental data. This evolution positions light not just as illumination, but as a critical data conduit and a customizable environmental parameter that interacts seamlessly with other building management systems for HVAC, security, and space utilization, creating truly responsive and human-focused environments.
