American enterprises Sorra is committed to the establishment of white LED lighting

According to science news reports, University of California-Santa Barbara (UCSB) Professor Nakamura Shuji (Shuji Nakamura) co founded the American LED lighting company Soraa, recently in Yokohama set up offices in Japan, May 2015 is expected to formally established Incorporated Company in Japan, will expand the LED lighting business, fully develop the Japanese market.

2008 in the village and two professors UCSB create Soraa, in 2012 began selling LED lights, the company's total turnover growth of up to 4 billion yen. For the Japanese market, Soraa in two years ago through the Japanese oxtail (USHIO Lighting) to sell the LED light source lamp, this time in the day announced the establishment of the company, Japan turnover target in 2015 than in 2014 doubled to 300 million yen.

Soraa is committed to creating the most natural light white LED lighting, its products are mainly used in high-end restaurants, restaurants. In general, we see the white LED, is made of blue LED chip to stimulate the yellow fluorescent material, the light wavelength and color temperature is not uniform, it is not easy to improve the average color rendering evaluation index (Ra).

Soraa is a purple LED chip, with red, green, blue fluorescent material composed of white LED, can output all the visible light wavelength range, and higher Ra value. Soraa uses gallium nitride (GaN) substrate to grow GaN crystal "GaN on GaN" technology to produce purple LED, its crystalline quality is higher than that of sapphire (Sapphire) or silicon carbide (SiC) substrate.

According to the Nikkei Technology Online reported that the general LED chip is four angle, while the purple LED Soraa chip shape is a unique triangle, higher luminous efficiency. Because of its good crystalline quality, so the triangle is not easy to damage and can fully shine.

In the village, said the blue LED itself has a color difference, so that the white light generated error; Soraa purple LED produced by the white with color consistency, more clean and beautiful. Nakamura and Soraa continue to focus on GaN on GaN technology to perfect the crystallization of fine LED lighting products.

Soraa was founded in Japan this year, plans to three years after the initial public offering (IPO).
