- Downwind International owns the world's original patented LED lighting technology On January 8, 2016, Shunfeng International Clean Energy Co., Ltd. announced that at its 2015 National Science and Technology Awards Conference held in Beijing's Great Hall of the People, Sunfeng's Jingneng Photoelectricity (Jiangxi) Co., Ltd., Nanchang University, Co., Ltd. jointly completed the "high-efficiency GaN-based silicon substrate blue light-emitting diode project" won the only first prize of national invention of technology. Mr. Luo Xin, Executive Director and CEO of Windwind International commented on this: "At present, there are three LED technology routes in the global semiconductor lighting field. They are the LED technology route of sapphire substrate, silicon carbide substrate and silicon substrate respectively. The first two The patented technologies of the technology route are monopolized by the United States and Japan respectively. After ten years of research and development, China has finally obtained the complete patent of the silicon substrate LED technology with original intellectual property in the field of semiconductor lighting, It is my honor to take the lead in bringing this original LED technology to industrialization, so I am honored to have won the only first prize for this technology in our country, and to R & D led by Professor Jiang Fengyi, Dr. Sun Qian and Dr. Wang Min The team warmly congratulates. " In the field of LED lighting technology, the silicon substrate has good thermal conductivity, and has the advantages of low cost of raw materials and large wafer size. The silicon substrate LED lighting product developed by the crystal photovoltaic has the advantages of low cost, high power and directionality Good advantage, not only for ordinary civilian lighting, but also for stadium lighting, street lighting and car lighting, etc., compared with the sapphire and silicon carbide LED technology, its application is more broad. In 2006, Professor Jiang Fengyi and Dr. Wang Min co-founded the crystal photovoltaic, focusing on the industrialization of silicon substrate LED technology. It has successively obtained the A-round investment from Jinsha River Venture Capital, the B-round financing led by Singapore Temasekam, the International Finance Company C (IFC) led round C financing and Asia Pacific-led round D financing. In May 2015, Downwind acquired 59% of the issued share capital of Crystal Power, making it an important part of the city's comprehensive low-carbon energy-saving solutions.
Cycloaliphatic Epoxy Resins, also known as CCP (Cycloaliphatic Epoxy Resin), are a type of high-performance epoxy resin. They are a subclass of epoxy resins that are based on cycloaliphatic compounds, which offer unique advantages over other types of epoxy resins.
CCP epoxy resins offer excellent mechanical properties, such as high strength, stiffness, and dimensional stability. They also have excellent chemical resistance and can withstand exposure to harsh chemicals, acids, and solvents. In addition, they have excellent electrical properties, including high dielectric strength and low dielectric constant.
CCP epoxy resins are commonly used in a wide range of applications, such as coatings, adhesives, laminates, and composites. They are particularly well-suited for applications that require high performance and durability, such as aerospace, marine, and electronic applications.
One of the unique advantages of CCP epoxy resins is their ability to cure at low temperatures. This makes them ideal for use in applications where high temperatures cannot be used, such as in the electronics industry. They can also be cured quickly, which can reduce processing times and increase productivity.
CCP epoxy resins are available in a variety of grades, each with its own unique properties and applications. They can be used alone or in combination with other resins to achieve specific performance characteristics.
In summary, CCP epoxy resins are a type of high-performance epoxy resin that offer excellent mechanical, chemical, and electrical properties. They are commonly used in applications that require high performance and durability, such as aerospace, marine, and electronic applications. They are unique in their ability to cure at low temperatures and quickly, making them ideal for use in the electronics industry.
