Nanotechnology and LED Lights

LED lights

Nanotechnology has conquered the manufacture of LEDs, making LED lights more efficient than ever. LEDs with nanotechnology are the next generation of the LEDs we know, and they are gradually taking over the market. Today, we’ll take a closer look at nanotechnology and its relation to LED lights.

What are LEDs?

LED lights

Light emitting diodes or LEDs consume less energy. They don’t build up the heat, but they can provide more light. With nanotechnology, around 20% of the discharged light is reflected back into the diodes through the substance itself, thereby making the light more useful and somewhat reusable. The rate of light lost is based on the elements incorporated in the diode, but the usual rate is 20%.

How is nanotechnology used in LEDs?

Nanotechnology produces thousands of tiny holes, which are around 400x narrower than a human hair, on the diode’s surface, permitting more light to be released by the LEDs.

LEDs with nanotechnology are clearly costlier compared to the usual LEDs, which is why nanoprint technology was used by manufacturers. This makes LEDs more affordable, brighter, and more efficient. And because less light is cut off within the diode, less heat is also emitted from LEDs with this technology. Furthermore, nano LEDs have a higher color rendering index coupled with a wider range of color temperature.

What are the applications of nanotechnology in LEDs?

nano led tv by LGThe nano led TV was one of the first applications of this technology, wherein nanotechnology was utilized to provide a higher-quality picture. The earliest TV set with nanotechnology is the LD LEX8, and it used a panel of nanodots and a vast array of LEDs for the backlight. The TV combined LED and LCD technology in this one. Adding nanotechnology made the pictures clearer, sharper, and smoother. Plus, the TV itself was thinner (0.88cm) compared to other LG products.

Nanotechnology and Beyond

Researchers from the Academia Sinica and the National Cheng Kung University in Taiwan found that when gold nanoparticles are embedded into the leaves of a plant, the plant will illuminate the red light. They hope that thisbio-luminescence can be further developed by generating trees with bio-LEDs which could light streets. These developed trees could also undergo photosynthesis at night, absorbing carbon dioxide even when there’s no sunlight.
