Analysis of the prospects for the development trend of graphene and its application in LED lighting

OFweek semiconductor lighting network as nanometer material world's thinnest and most hard, Shi Moxi (Graphene) since its inception, has been sustained attention industry. It is understood, "2014 Chinese international graphene Innovation Conference" held in Ningbo in September 1st in the morning, the General Assembly invited the authority to release the next 5-15 years global analysis of graphene market and investment opportunities in the report, international cooperation in the field of the research of graphene and graphene, initiated the international alliance. It is understood, a number of listing Corporation or its subsidiaries in the conference, including the olefinic carbon new material, Jinlu group, Yin Xi technology, Sinoma International etc.. In addition, there are China Baoan subsidiary Shenzhen BTR Nano Technology Co., Ltd., a subsidiary of Shandong Xinhua Xinhua Kam Kam graphite materials Co. Ltd., the combined force of shares of Changzhou two-dimensional Carbon Co. in column. Graphene is a single layer of carbon atoms of sheet structure of new nano OFweek semiconductor lighting materials, is the human found almost perfectly planar atomic structure, its excellent conductive, heat conduction and heat dissipation performance to all walks of life are placed great expectations on their. Because have many excellent optical, mechanical, electrical and quantum properties, graphene is expected to launch a variety of applications in electronics, new energy, high-end manufacturing, medical and other fields. The next downstream application market is expected to reach trillion yuan level, is expected to be applied to the first transparent electrode, solar energy heat dissipation material and touch screen fields. At present, there are many problems difficult to machining metal materials, energy consumption, large density, conductive, easy deformation and difficult to recycle waste in LED cooling applications, almost no too big price space. The nano graphene conductive plastics such as used in the cooling of LED lamps, the cost of the system can reduce at least 30%. Graphene belongs to the rare earth materials, the heat conduction part is gradually replace metal parts used in LED lamp comprises a lamp holder, lamp cup, cooling and shell etc.. Graphene compared to metal materials, has the advantages of uniform heat radiation, light weight, flexible characteristics of the shape design. With the rapid development of LED industry, greatly boosting the development of upstream materials industry, but also further promote a breakthrough in the field of high-end materials. LED lamp used in heat conducting materials in large quantities, including the LED chip package element, LED optical lens, light scattering components, efficient heat radiating element, the light reflection and light diffusing plate. Graphene is currently in the industrialization phase of assault fortified positions, in technology, technology and industry chain docking aspects need to invest a lot of resources. The key and difficult point of industrialization is the transfer of technology and the upstream and downstream industry chain integration, related materials preparation. Industrial Development American, British, Chinese, Japan and South Korea and other countries in the forefront of the relative. All the time since, bad heat will cause the power supply damage, decay accelerating, short life and other issues, is always LED priority among priorities lighting system performance improvement. The three lamp casing heat radiating traditional materials also have their own advantages and disadvantages. Aluminum good thermal conductivity, conductive properties is not easy too safety; plastic insulation is good, but the thermal conductivity and expansion coefficient is relatively low; ceramic both before both insulation and heat dissipation advantages, fragile, high processing cost is the biggest ills. There are many problems difficult to machining metal materials, energy consumption, large density, conductive, easy deformation and difficult to recycle waste in LED cooling applications, almost no too big price space. The nano graphene conductive plastics such as used in the cooling of LED lamps, the cost of the system can reduce at least 30%. Graphene is a new nanometer materials composed of a carbon atom monolayer sheet-like structure, is the human found almost perfectly planar atomic structure, its excellent conductive, heat conduction and heat dissipation performance to all walks of life are placed great expectations on their. Compared with aluminum alloy and die casting of aluminum, if the use of heat radiating part plastic, comprehensive cost is reduced by more than 50%, the whole lamp processing cost decrease 30%, driving cost is reduced by more than 20%. Aluminum alloy material, widely used, various defects is more and more obvious, since the beginning of this year there have been many LED enterprises begin to focus on nano graphene plastic thermal conductivity material, the future is expected to be in the field of LED lighting large range popularization and fly graphene Tai Technology with high thermal conductivity material with high thermal conductivity, high insulation, "high flame retardant" and other excellent characteristics, and can replace the traditional metal radiator, provide solutions more excellent for decline in the overall cost of LED lighting products. No one China lighting lighting brands occupy the overall market share of 5%. From the present situation of the whole industry and channels of view, all of the LED enterprises have come to the crossroads, homogenization of products, similar to the marketing mode, the LED enterprise channel battle ahead of the opening, on the enterprise supply chain integration and optimization ability is also put forward higher requirements. New materials in the field of a major breakthrough in graphene is two-dimensional material, composed of a single layer of carbon atoms in the hexagonal honeycomb lattice structure is stable, the excellent physical properties. Discovery of graphene the subversion of the two-dimensional materials can not be condensed matter physics community previous existence in the finite temperature concept. Graphene has many excellent optical, mechanical, electrical and quantum properties of nano materials, is currently the most thin is the hardest, also has good light transmittance, high thermal conductivity, electron mobility of high performance, low resistivity, high mechanical strength and many ordinary materials do not have, the future is expected to in the electrode, battery, transistor, touch screen, solar energy, sensor, super light material, medical, seawater desalination and other fields of application
