LED light than ordinary light bulbs save up to 80% of the energy, life expectancy is about five times more than energy-saving lamps. Therefore, they are more and more frequently used as a light source. However, current manufacturing processes are either too expensive, or will cause the LED lamp life cut short. However, there is still room for improvement of white LED, Florida Atlantic University (FAU) researchers have now developed a new method for producing unusual: most of their LED lights are made from fluorescent proteins together.

    LED lights are an important part of our daily lives, whether at home, street or traffic lights and displays. They have many advantages, such as long life, high efficiency and environmental protection. However, the manufacture of white LED is extremely complex.

Find the perfect combination

    Current research mainly in two ways, the future can be used to make white LED. But they have their own shortcomings. A thin layer of the first method, an inorganic material such as phosphorus or the rare earth element is applied to the blue LED. This method of manufacturing the LED lights long life, with the best intensity light. However, due to the use of rare earth elements and the manufacturing process is complicated, leading to high production costs, it is not sustainable. Another method is to use an organic light emitting diode (LED), so that several organic semiconductor layer is sandwiched between two electrodes. Compared with inorganic materials, the lower the performance of this LED lights, a shorter life expectancy. Therefore, the best solution is to combine these two methods, each whichever is longer.

    FAU researchers have found that this combination has been successful - will be embedded rubber-like material applied to the LED fluorescent protein. Dr. Rubén D. Costa and his colleague Dr. Uwe Sonnewald from FAU Advanced Materials Cluster (EAM) joint research this invention.

Protein gel bed

    Dr. Rubén D. Costa explained fluorescent protein binding element required. They are very environmentally friendly, and low manufacturing cost. In addition, the protein allows color setting - color or white - is very easy to control. However, one obstacle is this: only protein in an aqueous buffer solution in order to maintain stability, which means using a standard coating process is unlikely. The researchers stressed, must also ensure that protein stability under various environmental conditions, such as under conditions of high temperature or humidity.

Their solution was to develop a new coating technology. Gel embedded proteins constituted by concentrated aqueous protein solution and a polymer compound. This polymer bound water protein solution to form a gelatinous network, while ensuring the necessary water retention. Then, this gel was dried in a vacuum, put it into a rubber-like material, which can be applied to multi-layer coating of light-emitting diode and a protective protein from external factors.

Dr. Rubén D. Costa excitedly explained:. ". Using this method, we can use an environmentally friendly and inexpensive manufacturing process to make a lasting, efficient white LED This is a major undertaking future development of LED"
