Researchers claim LED is about so much more than lighting

Researchers claim LED is about so much more than lighting

Monday 04 February 2019

We are now all aware of the energy-saving impact of switching to LED lighting, but there is far more to LED than first meets the eye. In a recent Nature “Perspectives” article, researcher Jeff Tsao outlines the concept of “engineered light” and how we are just on the verge of understanding the true power of LED.

According to Tsao, people who believe that LED is a simply an efficient upgrade to other forms of lighting are stuck in their thinking. It is better to think of “ light intentionally controlled in time, space and spectral content” which he says “can reward not just human optics with better lighting but also can help regulate human health and productivity by eliciting various hormonal responses.”

In addition, he goes on to say, LED lighting can be tailored to radically affect the growth, shape and nutritional value of plants which creates a new world of scientific and technological possibilities for indoor farming. When we add to this the possibilities offered by integrating LED into the internet of things, only then are we touching the tip of the iceberg in terms of what LED can offer.


LEDs for photons, physiology and food.
Engineered light could improve health, food, suggests researcher.
