Noble Prize in Physics goes to the inventors of blue LED


Anthony Byrne MP, Federal Member for Holt, caught up with Svetlana Zatsepin and Alex Zatsepin from Coolon LED Lighting today to celebrate the Nobel Prize in Physics for 2014 being awarded to Isamu Akasaki (Meijo University, Nagoya, Japan and Nagoya University, Japan), Hiroshi Amano (Nagoya University, Japan) and Shuji Nakamura (University of California, Santa Barbara, CA, USA) for the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources.

According to the Royal Swedish Academy of Science Press Release dated 7 October 2014:

“This year’s Nobel Laureates are rewarded for having invented a new energy-efficient and environment-friendly light source – the blue light-emitting diode (LED). In the spirit of Alfred Nobel the Prize rewards an invention of greatest benefit to mankind; using blue LEDs, white light can be created in a new way. With the advent of LED lamps we now have more long-lasting and more efficient alternatives to older light sources.”

“Many people are familiar with Moore’s Law, which is an observation that the complexity and performance of electronics doubles roughly every 1.5 to 2 years,” said Alex Zatsepin, Technical Director at Coolon LED Lighting. “This cannot continue indefinitely, due to the physical limitations of the dimensions to which components can be shrunk. The invention of new materials, in particular gallium nitride (GaN), which made the blue LED possible, allows electronics to move beyond Moore’s Law to enable better performance and innovation. It creates new opportunities that were unimaginable a few years ago.”

Australia remains at the forefront of the LED revolution. Residing locally in Hallam, Coolon LED Lighting, a leading Australian manufacturing company that produces world class LED lighting products, was particularly delighted to commemorate the Nobel Prize committee’s appreciation of research that is fundamental to advancing Coolon’s core vision of creating efficient, long-lasting and environment-friendly LED lighting.

Formed in Oakleigh in 2001, Coolon moved and expanded its R&D and manufacturing facilities to Hallam and currently employs over 40 personnel. Coolon invested heavily into R&D in order to utilize high quality LEDs to produce highly reliably performing products. The products from this research are now used on a daily basis around the world. Coolon’s LED lights are highly electronically sophisticated; in fact, they are probably closer to computers in complexity then they are to any conventional lamps. To compete successfully in the global market, Coolon LED Lighting is constantly improving and adapting its products to ensure it remains ahead of its competitors.

Coolon LED Lighting’s clients include mining companies, architectural firms and local governments like the Melbourne City Council, where its lights have been installed into many public projects. Coolon has been involved in Australia’s largest and most prominent projects, some of which have won industry awards, and have been recognized on the world scale.

By redirecting their expertise towards mining and heavy industrial applications, Coolon was able to create a range of industrial products that are now well known and globally recognized for being virtually indestructible. Coolon has since become an established supplier to many international mining leaders like BHP Billiton, Rio Tinto, Glencore, AngloAmerican, Barrick, and Xstrata, to name a few. The release of their first industrial product coincided with the GFC; however, during these tremendously challenging times, Coolon’s high performing products were sought by mining companies which helped Coolon to sustain stable growth, while ensuring mining companies by substantially reduced their lighting maintenance costs.

“It is wonderful to visit Coolon LED Lighting and celebrate the news that the 2014 Noble Prize in Physics was awarded to the inventors of blue LED. Coolon LED Lighting is an innovative local manufacturing company that produces high quality and world leading LED Lighting products. It is imperative that we support local manufacturers like Coolon into the future”, said Mr Byrne.

“When Isamu Akasaki, Hiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors in the early 1990s, they triggered a fundamental transformation of lighting technology. Red and green diodes had been around for a long time but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.

They succeeded where everyone else had failed. Akasaki worked together with Amano at the University of Nagoya, while Nakamura was employed at Nichia Chemicals, a small company in Tokushima. Their inventions were revolutionary. Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.

White LED lamps emit a bright white light, are long-lasting and energy-efficient. They are constantly improved, getting more efficient with higher luminous flux (measured in lumen) per unit electrical input power (measured in watt). The most recent record is just over 300 lm/W, which can be compared to 16 for regular light bulbs and close to 70 for fluorescent lamps. As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving the Earth’s resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluorescent lights.

The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: due to low power requirements it can be powered by cheap local solar power.

The invention of the blue LED is just twenty years old, but it has already contributed to create white light in an entirely new manner to the benefit of us all.”

“The invention of blue LEDs is a tremendous achievement in its own right, but the impact of this technology will reach much further,” said Mr Zatsepin.
