New Perspectives on Lighting

Dear Colleagues,

Lighting has experienced dramatic developments in the last two decades. The simplest example to understand this dramatic change is the fact that just twenty years ago, we suspected that we humans have one more photoreceptor in addition to the apparently well-known rods and cones, but did not know what it was. After ipRGCs were identified as the photoreceptors initiating at least one non-visual path, the lighting research community has been undergoing a revolution, and its consequences for safety, ergonomics, medicine, psychology, productivity and many other fields will not be fully understood in the short term. If other revolutionary milestones such as the massive introduction of LEDs in fields such as automotive lighting, indoor and outdoor lighting or the progressive introduction of infrared lighting are considered in parallel to the new perspectives brought by the discovery of ipRGCs, lighting can be considered one of the most exciting and challenging branches of technical knowledge. The present Topic will be focused on the new perspectives of this discipline and the unexpected applications that could appear in the future.
