Feitai Technology Dong Pei shares the application of nano graphene thermal conductive materials

On April 11, after Guangzhou, Xiamen and Hangzhou, the Zhongshan Station, the fourth station of the 2014 China LED Lighting Supply Chain Good Product Tour Symposium hosted by Gaogong LED, was successfully concluded.

The rapid start-up of the global LED lighting market comes from the rapid application of disruptive technology and the optimal control of enterprise supply chain costs. The global competition in the Chinese market has brought several advances. The first is the globalization of supply chains, and the second is the rapid improvement of localized OEM/ODM capabilities.

For LED lighting companies, the era of simply price is not the foundation for the survival of excellent enterprises. The cost of channel development is getting higher and higher, and the homogenization of products is getting more and more serious. What should enterprises do? Where is the way out? Many companies are secretly improving the supply chain, segmenting the market and optimizing the product structure. What are the next three years? Is the supply chain.

This Zhongshan Station seminar once again invited Dr. Zhang Xiaofei, Chairman of Gaogong LED, Li Zhaohua, Deputy General Manager of Mingwei Electronics, Zhang Zhennan, R&D Manager of Jingtai Optoelectronics, Dong Pei, General Manager of Feitai Technology, and Lin Jiliang, General Manager of Mulinsen Lighting, etc. The theme of LED lighting industry, packaging new materials, new processes, selection of LED driver power, nano-graphene thermal materials and LED lighting application trends, market structure and other topics delivered a keynote speech.

For a long time, poor heat dissipation can cause problems such as power supply damage, accelerated light decay, and short life. It is always the top priority of LED lighting system performance.

The traditional three kinds of lamp housing heat dissipation materials also have their own advantages and disadvantages. Aluminum heat conduction is good, because the conductive properties are not easy to pass the safety; plastic insulation is good, but the thermal conductivity and expansion coefficient are relatively low; ceramic has both the insulation and heat dissipation advantages of the former two, fragile, high processing cost is its biggest drawback.

In the view of Dong Pei, general manager of Feitai Technology, there are many problems in the application of metal materials in LED heat dissipation, such as difficulty in processing, energy consumption, excessive density, conduction, deformation, and difficult recycling of waste materials. There is almost no room for price reduction. Nano-graphene thermal conductive plastics, such as those used in the cooling of LED lamps, can reduce system cost by at least 30%.

Graphene is a nano-new material with a single-layered sheet-like structure composed of carbon atoms. It is an almost perfect planar atomic structure discovered by human beings. Its excellent electrical conductivity, thermal conductivity and heat dissipation properties are given to all industries. High hopes.

"Compared with aluminum alloy and die-cast aluminum, if the heat-dissipating plastic is used, the overall cost of heat dissipation is reduced by more than 50%, the processing cost of the whole lamp is reduced by 30%, and the driving cost is reduced by more than 20%." Dong Pei said that after extensive use of aluminum alloy materials Various defects have become more and more obvious. Many LED companies have begun to focus on nano-graphene plastic thermal conductive materials this year. In the future, they are expected to be widely used in the field of LED lighting. With excellent characteristics such as "high thermal conductivity, high insulation, high flame retardant", it can replace traditional metal radiators, providing a better solution for the reduction of the overall cost of LED lighting products.

Asymmetric Thyristor is the abbreviation of thyristor, also known as Silicon Controlled Rectifier, formerly referred to as thyristor; thyristor is PNPN four-layer semiconductor structure, it has three poles: anode, cathode and control pole; thyristor has silicon rectifier The characteristics of the parts can work under high voltage and high current conditions, and their working processes can be controlled and widely used in electronic circuits such as controlled rectifiers, AC voltage regulators, contactless electronic switches, inverters, and inverters.
