It is reported that researchers at Sandia Laboratory say that LED lamps are "just at the beginning stage", saying that LED-based "engineering lighting" can be used as a signal of specific physiological reactions of human beings and plants, as well as to promote the production of fresh food.

In short, LEDs offer many advantages for health and production, which have not been discovered before.

Researchers say that intentional control of the time, space and spectral content of LED lamps, which they call "engineering light", can trigger hormone responses that help regulate human health and productivity.

Specific LED wavelength and intensity can also effectively stimulate plant growth, change the shape of plants and increase their nutritional value. In this way, it may bring new possibilities for indoor planting.

Researcher Jeff Tsao said: "This approach is not to ignore the integration of LED and the Internet of Things (IoT). At present, LED has been integrated with the electronics, sensors and communications industries."

Researchers believe that the ever-expanding use of LED will bring greater value to society, far more than the energy saved by housing and building lighting.
