The characteristics of semiconductors made of miniature LEDs (Ligot-emitting diode) is today Gazeta Wyborcza. As the author writes, thanks to research scientists Isamu Kasaki, Hiroshi Amano and Shji Nakamura , kind-hearted and popular bulb thing of the past. This is another triumph of conquering semiconductor electronics since the invention of the transistor.
Diodes perfectly complement conventional bulbs – they are very small, and seems durable. Do not spoil for 30 years, they are comparable to the size of a grain of sand and consume. Seven times less energy.
The first LEDs already appeared a few decades ago, only in red. Then came the time for the LEDs orange or yellow. Wyborcza writes, however unsuccessfully sought a semiconductor glowing blue. You are lucky to choose the right semiconductor. The Japanese put on gallium nitride and succeeded where even losing laboratories powerful electronics companies.

Cooperation of three scientists from the country of the rising sun and technological revolution has resulted in billions of savings on a global scale. Today, the world of the lighting consumes up to 30 percent. energy. Energy-efficient LEDs can also change the way we think about lighting of cities and houses, which have not changed for centuries – writes Gazeta Wyborcza.
Diodes break because of the limitations of design are small, they can be create great panels and flexible mat, put on the floor, the edges of the frames, furniture, even the grout between the tiles. In the so-called. LEDs RGB colors can be infinitely varied. The limitation begins to be only imagination.
Gallium nitride was known in the late 60s, did not seem to meet the hope. The success waited for 90 years, when the art technology for mass production and start selling. The first great and colorful screens road went to Las Vegas, Japan and South Korea. Prices gradually declined and LED began to displace the traditional streets of neon lights and bulbs. LEDs have proven to be a crucial step to obtain the blue laser used in Blu-ray players and video consoles.
Certainly, few know that Polish science is this your little part. In 1993, the Japanese developed the first diode of gallium nitride, and semiconductor dealt with physicists from the University of Warsaw and the Polish Academy of Sciences. Suddenly fame, breeding high quality single crystals of gallium nitride has been so far a Polish specialty. As reported by the Electoral two years ago, Poland has Ammono founded by graduates of the Warsaw University and polytechnic was laureate of the CS Industry Awards which is how Oscar for best electronics industry.
