The error of LED phosphor patent and product?

Recently, the circle of friends and the public number is how powerful Japan to refresh it, regardless of the number of enterprises and innovation patent layout, Japan is actually the way ahead, the number from 2016 to Nichia patent rights cases can be seen. - 2016 Nichia patent rights case enterprise writing this article is not to write the Japanese more powerful in the LED patent, but when we are in such a situation, but do not know the situation, we should know what to ignore. For a deeper analysis of the misunderstanding of LED phosphor patent and products, LEDinside consulting with Dr. Liu Ronghui of the Institute of rare earth. A misunderstanding: the patent barrier is phosphor fluorescent powder has been patented as everyone knows, is an important force in the LED industry, phosphor patent litigation has great influence on the whole LED industry. Especially, in recent years the study of the role of sub chemistry from low-key to high-profile activist role conversion, pick up a lot of patents, patent war, caused some LED manufacturers worry. This patent rights war intensifies, as a result of a mistake about patent infringement is caused by the fluorescent powder, but that is not the case. Although the fluorescent powder is one of the key materials of LED package, but it is only necessary to constitute one of the white light device component. In addition to individual novel nitride phosphor, phosphor alone is in fact no infringement. Misunderstanding two: patent application has little effect in the current LED phosphor patent war, through the new fluorescent powder composition and structure and application of the patent, really become an important way to break foreign patent white devices, and many enterprises are using this way to contain foreign patents, and has made certain effect. But the market came out is not what this patent, no substantive role, but not so. In fact, any patent protection of intellectual property rights, innovation, but it is not the limiting successor. For although foreign made the initiative in the fluorescent powder and white LED devices, but does not prevent domestic units subsequent acquisition of intellectual property rights. For patent, we have to do is to respect the existing intellectual property rights, but also can not talk about the mere mention of intellectual property rights. Any patent has its limitations, the technology involved are in progress, make a concrete analysis to specific patents covered by subsequent technological innovation to break through the existing patent restrictions are possible. This grirem, Dr. Liu Ronghui said, the people do not think subsequent patent domestic application is useless, even if the utility model patent gold content is low, as long as there is a role for the application value, enhance product performance, is the value of the patent. From the domestic phosphor patent application perspective, in recent years in the domestic patent LED fluorescent powder application field is very active, and from universities and research institutes to apply for a patent, paying attention to the patent application slowly to enterprise, it is very important to enhance the China phosphor and LED devices in the field of patent strength. Misunderstanding three: domestic fluorescent powder from not good to go to Japan to buy toilet cover events, all is good in the transmission of a Japanese things concept, but people in the LED industry did not understand the nature of things. Many people say that product sophistication of domestic products is not up to the foreign countries, domestic is not to do, but because of the domestic market mainly by price oriented. From raw materials, manufacturing LED fluorescent powder in the world is the main raw materials of rare earth Chinese production, this point at home and abroad at the same level. However, the selection and control of raw materials abroad is very strict, in order to ensure product quality. Due to different market conditions, domestic customers focus on the price of the raw material selection on the randomness, the supplier of raw material to control the standard wide. Grirem to control the consistency of the product, most of raw materials for the production of LED phosphor is made, such as the core raw material LuAG, nitride and fluoride phosphors are a research group within the custom. Take the current equipment kiln, the market is coming out of the temperature control precision and the fluctuation of temperature and uniformity of the majority of domestic kiln, not foreign kiln. In fact, not so broadly, has always been the ambiguity of the status quo. The kiln should be divided into three parts to see. First, the current market mature YAG system and structure system of 1113 nitride phosphor, fluorescent powder for the two series of domestic equipment factory and domestic phosphor manufacturers after so many years of equipment research, has not much difference in and abroad, this kind of equipment has been made. Secondly, the new system of fluorescent powder (such as nitride green powder) put forward higher requirements for temperature and pressure equipment, meet this kind of fluorescent powder equipment, currently made from the highest temperature, the maximum pressure, and the stability of equipment and other countries still have obvious difference. Finally, in need of new equipment to meet the phosphor system process of fluorescent powder preparation (such as the new fluoride system of this kind of equipment), there are no manufacturers sell directly, which requires the understanding of the process of the fluorescent powder factory, and then plant the common development of new equipment, the difficulty is high, regardless of the quality problem, which is currently the world's production to achieve fluoride focus on the reasons for a handful of phosphors developed stronger in the enterprise.
