#Scientists Create LEDS From Food, Beverage Waste Most Christmas lights, DVD players, televisions and flashlights have one thing in common:
theye made with light emitting diodes (LEDS. LEDS are used widely for a variety of applications
and have been a popular, more efficient alternative to fluorescent and incandescent bulbs for the past few decades.
Two University of Utah researchers have now found a way to create LEDS from food and beverage waste.
this development can also reduce potentially harmful waste from LEDS generally made from toxic elements.
LEDS are a type of device that can efficiently convert electricity to light. Unlike fluorescent and incandescent bulbs,
LEDS direct 80 percent of the energy consumed to producing light. This is made possible by the fact that LEDS do not require a filament to be heated as incandescent and fluorescent bulbs do.
LEDS can be produced by quantum dots, or tiny crystals that have luminescent properties. Quantum dots (QDS) can be made with numerous materials, some
of which are rare and expensive to synthesize, and even potentially harmful to dispose of. Some research over the past 10 years has focused on using carbon dots (CDS),
to create LEDS instead. Compared to other types of quantum dots CDS have lower toxicity and better biocompatibility,
and subsequently, LEDS. The results were published recently in Physical chemistry Chemical Physics, a journal of the Royal Society of Chemistry.
heated and hardened to solidify the CDS for practical use in LEDS. An environmentally sustainable alternative Currently, one of the most common sources of QDS is cadmium selenide,
To be able to use this waste for creating LEDS which are used widely in a number of technologies would be an environmentally sustainable approach.

One obvious answer is to convert greenhouses from the traditional incandescent lighting usually high pressure sodium lamps to more energy-efficient LEDS.
but the industry has been slow to make this change because of the high initial cost of LEDS.
These guys have compared the life-cycle costs of traditional high pressure sodium lamps against those of LEDS for greenhouse lighting.
They calculate that the cumulative cost of high pressure sodium lamps surpasses that of LEDS after just seven years
and that after 16 years the cumulative cost of high pressure sodium lamps is more than double the equivalent cost of LEDS.
Although high pressure sodium lamps are individually cheaper than LEDS they have to be changed every year compared to every 19 years for LEDS.
And of course LEDS use considerably less electricity wasting little as heat. But the most interesting part of Singh and co s analysis is in the potential of LEDS to change the way that vegetables are grown.
