Through technology to spy on graphene in the field of LED lighting business opportunities have how old?

As the most thin, the hardest, now find strongest conductive heat conduction performance of a new type of nanometer materials, graphene is called "black gold", is the king of new materials, scientists even predicted that graphene will completely change the 21st century, and news about the special application of graphene is constantly come up to the most thin light bulb; Mobile phone charging it only takes a few seconds... 
Believe that a lot of researchers, domestic enterprises have long been devoted to research, the application of graphene as technology advances, the future, will certainly to fight a global wave of graphene preparation and application of industrialization. 
So in the field of LED lighting, graphene and what can be done? The following led people from the perspective of patent to a look at the development of technology. 
After simple in Chinese database retrieval, found that graphene in lighting applications in the field of patent application in China started in 2008, after the application increasing every year, for an application for a patent has accumulated more than 1000, more than 90% of applicants from domestic applicants. H01L and F21S two categories, the application in the field of F21S basic is a domestic applicant, the main is to use the performance of thermal conductivity of graphene, coated with the light source or surface heat lamps and lanterns, the applicant is more, mainly composed of enterprises and individuals to apply for, do not describe here. 
In the field of H01L, the top ten of the applicant is mainly domestic scientific research institutes and universities, enterprises have boe, IBM and South Korea's samsung, which IBM application mainly in the field of power semiconductor devices, South Korea's samsung application involves has LED, OLED and display devices, and other areas of the lighting. For samsung in China in the field below the patent application has publicly do one overview, for readers reference. 
Can be seen from the table above: 
1, samsung of graphene in the field of lighting in China patent application is started after 2011, at present basically has not been authorized. This shows that in the field of application for a patent, giant is not in how much time than in the domestic leading situation still has a lot of variables in the future. Stepping up research and development, the domestic enterprises strengthen the consciousness of intellectual property and is expected to catch up with foreign firms. 
2, these patents mainly relates to the LED, and OLED display device field, in summary, can be divided into two categories: 
1) overturn type: represented by patent 1, by the graphene material to replace the current semiconductor compound light; It is using another way to achieve the same purpose, overturned before practice. 
2) modified: represented by patent 2-8, add a layer of graphene materials on the original structure (3,4,6,7,8), due to the transparent graphene, conductive, thermal conductivity and a series of advantages, after adding can make up the shortfall, which has obtained the remarkable effect of technology; Or directly to the graphene material for the original patent (5), which has made significant technical effect. In the majority with advanced patent, this patent technology difficulty is relatively low, the domestic enterprises in the application for a patent for this type of strength is not weak in foreign company, and long-term OEM, technical staff has accumulated plenty of experience, more easily in combination with the characteristics of the new material, the improved technical solution is put forward. 
In conclusion, graphene in lighting applications in the field of technology development is still in the growth stage, and the advantage of foreign companies are not obvious, domestic enterprises and research institutions, to strengthen investment, believe that there is a chance to catch up with foreign technology, in the future to gain a foothold in the market.
