Smart Lightning Filter

This concept explores a simple retrofit solution allowing for automated light tonality changing. It acts as a cheaper alternative to dynamic white LEDs to address the ongoing research on human-centric melanopic lighting. Melatonin is the key to our circadian retheme (pattern of wakefulness and sleep). The production of this hormone is suppressed during the day by a naturally blue-rich light environment. We steadily fall asleep at night when there is very little blue in our light. As LED technology is developing further, a lot of explorations has been performed to understand the relation between worker’s productivity and the application of blue lights to maintain alertness.
