Human-Centric Lighting Made Simple with Automation  

While the concept of human-centric lighting is not new, the technologies available to support that goal continue to evolve. This course discusses the importance of lighting for occupant well-being, and how to achieve that. This includes daylighting, electric lighting that mimics the rhythms of natural light, and automated shading to prevent glare. A primer on the intricacies of lighting color and dimmable white light provides deep knowledge for specifiers. A striking case study shows the potential when a sophisticated lighting design team provides input at the beginning of the design process. Before the invention of electric lights, gas lamps, and candles, humans lived and worked under the natural rhythms of daylight. Daylight is a dynamic light source that changes daily (dark/light), seasonally (sunrise/sunset times), and within the day due to weather changes. This dynamic nature of daylight creates visual interest through color temperature, distribution, and brightness changes. Firelight is the next natural light source in the evolution of lighting. This light source was not controlled until humans learned how to create and harness fire. It is a dynamic light source that moves, emits various warm tones, and provides a relaxing environment.
