Engineering LED Light Could Improve Human Health
We all know by now that the LED is a true triumph in lighting. Not only does it provide us with clear and high-quality light, but it also consumes much less energy to work at the same brightness which is both beneficial for you, your pocket and the environment! But now, researchers may just have found a way to engineer LED light to make a difference in all aspects of human life! Read on for more info!
Jeff Tsao (who's pictured below) and his fellow researchers from Sandia National Laboratories published an intriguing article called "Perspectives" in Nature in late November 2018. The article has since been challenging the way that we think about light and what it can do.
Whilst we might view the current LED as a highly-developed and sophisticated piece of technology, the authors of the paper claim that "LED lighting is only in its infancy." They continue;
"We now stand at the threshold of what might be called engineered light."
But what exactly do they mean by engineered light? Well, they believe that LED light could be intentionally controlled in time, space and spectral content! This means advances not only for our eyes and the light that they can perceive, but also for our health.
Although LEDs have already been used and widely adopted in the professional medical sphere to treat health issues such as bladder, eye and skin problems, Tsao and his fellow researchers seem to be suggesting a complete shift in the way we regard LED lighting.
In a similar way to the way LED lighting is utilised to help conquer the mental and physical effects of SAD, they believe that LED light's further engineering will help regulate human health and productivity by controlling various hormonal responses.
Alongside these advances, the researchers also cite the awe-inspiring way that LED light can be controlled to stimulate growth in the agricultural sector. Using tailored wavelengths and intensities, LED light can not only encourage plant-growth, it can also cause them to alter their shape and increase their nutritional value, making indoor farming easier than ever before.
As you'll see in the picture below, red and pink LEDs have been shown to produce the best growth in plants.
And, of course, LEDs are most commonly known for their light-giving abilities, but even this aspect of the LED is open to innovation. As Tsao asserts, "the integration of LEDs with the internet of things [electronic circuits that can communicate with each other]" is now becoming increasingly widespread. He adds "[this] is already happening with LED integration with electronics, sensors and communications," referring to the Smart devices that we are seeing more and more of on our shelves.
In total, the authors surmise that LED lighting and its inevitable growth could be of much more value to society than simply lighting homes and saving energy in the process. That's certainly something we've seen here at LED Monkey and will no doubt continue to see as we edge towards an ever-brighter future!
