Graphene is nanotechnology and new materials a monolayer sheet structure composed of carbon atoms, is almost perfectly planar atomic structure found in humans, and its excellent electrical conductivity, thermal conductivity and thermal properties make their trades were placed expectations.
Looking 10K3MR1I 2ST5949, http://www.oemsemi.com is a independent distributor for thousands of electronic parts, get quote from our web will be responsed in 24 hours, trading electronic parts from our web now.
With its numerous excellent mechanical, optical, electrical and microscopic quantum nature of graphene is expected in the electronics, new energy, advanced manufacturing, medical and other fields to expand a variety of applications. Future downstream applications market is expected to reach one trillion yuan level, is expected to be the first transparent electrode used in solar, thermal materials and touch screen and other fields.
Currently, the presence of metallic materials in the LED heat dissipation applications difficult to process, consuming energy density is too large, conductive, easily deformed and difficult to recycle waste and many other issues, almost no big price cut. Graphene nano conductive plastic applications such as in LED lighting on cooling, which can reduce system costs by at least 30%.
Graphene belong to rare earth materials, are gradually replaced by metal parts used in LED luminaire thermal parts, including lamp, cooling heat lamp cup and shell. Graphene with respect to metallic materials, with heat evenly, light weight, design and flexible features.
The rapid development of LED industry, greatly boosting the development of upstream materials industry, but also further promote breakthroughs in the field of high-end materials. LED lamps use a lot of heat conductive materials, including packaging components LED chip, LED optical lens, light scattering element, efficient cooling components, light reflection and light diffusion plate.
Graphene is currently in a critical stage of industrialization, in technical, technological and industrial chain docking areas need to invest a lot of resources. Industrialization key and difficult is the preparation of related materials, transfer of technology and downstream industry chain integration. Industrialization development of the United States, Britain, China, Japan and South Korea and other countries in a relatively forefront.
All along, the poor heat dissipation will cause damage to the power supply, the light fades accelerated life cut short and other issues, LED lighting is always a top priority to enhance system performance. Three traditional heat lamp housing materials are also advantages and disadvantages. Aluminum thermal conductivity is good, too difficult due to the conductive properties of safety; plastic insulation, but lower than the thermal conductivity and expansion coefficient; insulation and heat combines the advantages of both the former ceramics, fragile, high processing costs is the biggest ills.

And aluminum and die-cast aluminum compared, if the heat plastic, heat part of comprehensive cost reduction over 50%, the entire light processing costs reduced by 30%, reduce the drive cost more than 20%. After extensive use of aluminum alloy material, various defects and more obvious that this year there are already many LED companies began zeroed regard to nanographene thermal plastic material, which is expected in the future popularity of a wide range of LED lighting in the area and flying Thai high thermal conductivity material graphene science and technology with the “high thermal conductivity, high insulation, high flame” and other excellent properties, can replace traditional metal radiators, providing more excellent solution for LED lighting products decreased overall costs.
