Human-centric lighting – what does it mean and how do we provide it in practice?

Patricia Rizzo

Human-centric lighting is lighting devoted to enhancing vision, wellbeing and performance individually or in some combination. As such, human-centric lighting must consider the effects of light exposure on both visual and non-visual aspects of human physiology in a lighting design – and lighting design is increasingly called upon to support circadian, or non-visual, needs for users across societal segments. Home or hospital, office or classroom, recognition that disruption of 24hr rhythms can impact mood, alertness and performance presents new challenges to development and deployment of lighting systems. The awareness and scientific evidence that people need the right light at the right time for their health and wellbeing has grown considerably in recent years. As such human-centric lighting starts to play an essential role in creating attractive value-to-customer propositions beyond energy savings. This presentation will look at the broad umbrella of human-centric lighting, explain circadian light, show examples of application techniques, and look at the tools and technologies available to support both.

Learning objectives

  • Distinguish between the visual and non-visual pathways
  • Understand how the human circadian system functions
  • View examples of lighting design and application techniques for healthcare or office
  • Explore technologies available to achieve human-centric lighting benefits in practice

Patricia Rizzo, LEED AP, Sr. Lighting Applications Developer, Philips Lighting Research North America

From Lighting Design Program Manager and Adjunct Professor at Rensselaer Polytechnic Institute’s (RPI’s) Lighting Research Center to Senior Lighting Applications Developer at Philips Lighting Research North America, Patricia’s focus these last 16 years has been to bridge lighting research and design practice. Her lighting design projects have ranged from architectural to historic structures, from themed retail to campus master plans, from low vision senior care to memory care facilities. Regardless of the project, whether commercial or residential, indoor or outdoor, the ability of lighting to improve the environment for those using the space – young or old – has always been the priority. She currently works collaboratively with a team of lighting applications designers, scientists, and optical engineers to develop new lighting system concepts and propositions that embody the core principles of lighting for health and well-being, to help extend human-centric lighting to both indoor and outdoor spaces. Patricia holds a Master of Science in Lighting degree from RPI’s Lighting Research Center.

A light lunch will be served.
