Low-cost bio LED lights will boost vision and mood!

Jan 14, 2016: Scientists have found a great way to create a new form of LED light by packaging luminescent proteins in rubber form which will be cost-effective and shall additionally soothe our eyesight and enhance mood.

This innovative technology helps to create a ?bio? LED which gives off a white light created by equal parts of green, blue and red rubber layers covering on LED, thus giving the same effect as with traditional inorganic LEDs but at a much lower cost.

Low-cost ?bio? LED lights will boost vision and mood!

Rubén D’osta, a researcher at the University of Erlangen-Nürnberg (Germany) and co-author of the study spoke about a technology and a hybrid device called Bio-LED which uses luminescent proteins to convert the blue light emitted by a ‘normal’ LED and changes into pure white light.

LEDs are being manufactured using inorganic materials that are in short supply namely cerium and yttrium. As these materials are limited, they are more expensive and difficult to sustain in the long run.

Another important feature is, white LEDs produce a colour that is not suitable for eyesight as they lack a red component that may psychologically affect individuals exposed to them for long periods of time.

A collaborative German-Spanish team has gained inspiration from nature’s biomolecules to find a better solution. Their method consists of introducing luminescent proteins into a polymer matrix to produce luminescent rubber.

This method involves a new way of packaging proteins which could end up replacing the method used to create LEDs today.

The authors note that the white LEDs are made of an expensive and scarce material known as YAG:Ce (Cerium-doped Yttrium Aluminium Garnet) whereas blue or ultraviolet LEDs are much cheaper in comparison. Proteins will replace the source material in Bio-LEDs.

The Bio-LEDs are easy to manufacture and their materials are biodegradable and low-cost, meaning that they can easily be replaced and recycled.

Scientists are tirelessly working on optimising this new elastic material, to achieve longer operating lifetime and greater thermal stability.
