On February 9, Soraa, a California-based innovation company, announced the launch of its flagship product, a light-emitting diode (LED) lighting product called LED 2.0 technology.
It is reported that this new type of LED light bulb invented by Soraa is 10 times brighter than ordinary LED. A 12-watt bulb is as bright as a 50-watt halogen bulb, but it saves 75%. Therefore, this product is considered to be the first LED bulb that can be compared to a traditional 50-watt halogen bulb. Moreover, the product does not require a mechanical fan, and uses an optimized electrical design, making it fully compatible with common transformers and dimmers and can be used both indoors and outdoors.
The company’s senior officials did not disclose the cost of such light bulbs, but said that within 1 year, the cost can be recovered by saving electricity charges, unlike ordinary LED products that normally take several years to recover costs.
Soraa is the world's leading GaN developer and has developed the world's first commercial GaN LED product. Soraa was established in 2008. One of the founders, Shuji Nakamura, has the reputation of "the father of blue LED." Soraa's president and CEO Kim Bing-kook is also well-qualified. In the past, he served as vice president of the global marketing business unit of South Korea's Samsung Electronics, and was also the first external senior vice president of Intel.
Compared with incandescent bulbs and halogen bulbs, LEDs are a better choice because of their high efficiency, non-toxicity, and long lifespan. However, if the entire room is illuminated with LEDs, there are technical and cost challenges.
In general, LED fabrication involves growing a thin layer of gallium nitride (GaN) on a sapphire or silicon substrate. Soraa, on the other hand, uses GaN as a substrate, which reduces the mismatch between the two crystalline structures. In this way, Soraa claims to increase brightness by 10 times.
This is why Soraa technology is hailed as LED 2.0 technology.
It is reported that generally 50-watt LED lights need to integrate multiple light bulbs, but Soraa's LED lights only need a chip or diode to reach 50 watts.
Niobium nitride is significantly more expensive than sapphire or silicon-based materials. Colin Humphreys, director of research at Cambridge University's Department of Materials Science and Metallurgy and founder of semiconductor company CamGaN, believes that the use of gallium nitride in large areas is expensive - 6-inch diameter silicon wafers only cost $30, and 2-inch sapphire wafers are similar, but A 1-inch GaN wafer requires $500. “Soraa may be able to significantly reduce the cost of GaN wafers, but it is certainly not possible to achieve the same level as silicon wafers and sapphire wafers,†said Humphreys.
However, Jin Bingguo is not worried about this. He said that Soraa has mastered an innovative manufacturing technology that can greatly reduce the production cost of GaN, and claims that the cost of the substrate is only a small part of the entire light bulb, but the benefits obtained are far greater than the expenditure. “We have a simple, high-density light source that can reduce the system design, making it the most cost-effective product at the moment,†said Jin Bingguo.
Prior to this, Soraa obtained more than US$100 million in start-up capital through two rounds of financing and plans to sell the first batch of LED 2.0 products by the end of the quarter.
