Seoul Semi boosts LED brightness 5x with technology breakthrough

July 04, 2012 // Christoph Hammerschmidt

With a new technology dubbed nPola, Seoul Semiconductor claims it has achieved a breakthrough in LED lighting: nPola LEDs produce 5 times more light that standard LEDs with the same surface. What's more, Seoul sees the potential for a further tenfold light intensity increase.

The new product, which SSC holds the unique patented technology rights to, has been under development by SSC for over 10 years. The brightness has been dramatically improved by 5 times over the conventional LED on a same surface area and will be improved up to more than 10 times in the future. Currently, the brightness of a power chip LED in mass production is around 100 lumen but this new product, introduced by Seoul Semiconductor, produces 500 lumen which is 5 times better than a conventional product. As an example, when making a LED bulb for a 60W household bulb replacement, generally, 10-20 LED packages are used but when this new product is applied, the same brightness can be achieved with only 1-2 packages. 

During the technology presentation in Jong Lo Gu (Korea), Seoul Semiconductor CEO Jung Hoon Lee expressed strong confidence in the new product by saying "For the past 20 years, I've worked very hard in this industry and it is safe to say that this new product is the culmination of 20 years of core technologies. It is the final stage of the LED development process." SSC will immediately begin production of this new product, and it will start sales in strategic markets abroad. 

Professor Nakamura Shuji, who is also known as the father of LED, was also present at this event to comment on the technology of SSC. Professor Shuji Nakamura, continuously discussed as a candidate for the Nobel prize in physics, is currently a professor at the University of California, Santa Barbara, and is also an advisor to SSC.
