Infineon and Wanrun Technology were invited to join the G20-LED Summit
Recently, at the invitation of the G20-LED Summit Organizing Committee, Infineon Electronics (Hangzhou) Co., Ltd. and Shenzhen Wanrun Technology Co., Ltd. officially joined the summit.
The fresnel lens is a thin sheet made of plastic material. One side of the lens surface is smooth, and the other side is molded with concentric circles from small to large. Its grooves is designed from the interference of light, the relative sensitivity, and receiving angle requirements.
Compared to the conventional Spherical Lens, a Fresnel lens by the lens divided into a series of concentric circles theoretically infinite number of lines (i.e., the Fresnel zone) to achieve the same optical effect, while saving the amount of material For these lines, the overall thickness of the lens is reduced; ordinary Fresnel convex lens is actually a continuous curved surface is truncated to a section of a discontinuous change of the curvature as the surface is finely divided, so look like a
Fresnel lenses are mainly used in optical imaging industry ( projectors, VR, AR, etc.), Fresnel lenses are used in LED lighting distribution (spotlights, floodlights, stage lights, traffic signal lights), infrared induction lenses are used in ( industry 4.0 intelligent fields, building security systems, induction lighting, etc.), large Fresnel lenses are used in ( photovoltaic concentrated light generation, heat collection, light utilization, etc.).

Located in the National High-tech Industrial Development Zone on the south bank of the beautiful Qiantang River in Hangzhou, Infineon has gathered a group of world-class power development and design experts. Mr. Hua Guichao, the founder of the company, has a profound knowledge in the field of switching power supply. He has published more than 60 academic research papers in the world and obtained 16 US invention patents. He has served as a researcher at the Virginia Power Electronics Center (currently the world's largest research center for switching power supply technology) and one of the founders of VPT Inc., a well-known US power company, and served as vice president.
Infineon Electronics has shown rapid growth after it has become a major supplier of LED drivers for global lighting leaders such as Osram and Philips. At present, Infineon has applied for more than 100 patents related to LED driver power. In the future, the new generation of driver innovation with independent intellectual property rights will further consolidate Infante's position as the leader in the global LED driver power industry.
Founded in 2002, Wanrun Technology is based on the traditional LED packaging business. In recent years, it has vigorously developed LED application lighting products, focusing on the development of LED commercial lighting and road lighting products.
In 2010, Wanrun Technology's sales were close to 250 million yuan. At present, the company has more than 200 sets of fully automatic special equipment and testing equipment, nearly 1,000 employees, including more than 100 research and development personnel, and annual research and development funds account for 3% of sales revenue. At present, it has 43 patents and is assessed as the Shenzhen Power LED Packaging and Lighting Engineering Technology Research and Development Center, the Ministry of Science and Technology “Twelfth Five-Year†National Science and Technology Support Program, the semiconductor lighting industry technology innovation strategic alliance member unit, the National Development and Reform Commission key industry revitalization and Technical transformation plan demonstration unit.
As the representative of the most growing companies in the domestic LED industry, Wanrun Technology and Infineon Electronics joined the G20-LED Summit, which undoubtedly brought fresh blood. Dr. Zhang Xiaofei, Secretary General of G20-LED Summit, said: "Infineon is a typical technical enterprise. Wanrun Technology is a representative representative of typical packaging enterprises in South China. Each has its own characteristics. The development of China's LED industry requires such enterprises. Participating in them, they represent a part of the industry, and their voices can reflect the voice of a large number of companies of the same type." 
circle around the lines. Fresnel lenses may in fact be regarded as a series of prisms are arranged in a ring, wherein the relatively sharp edge, and the center of the convex surface is relatively smooth.
