LED phosphor patents and products have those errors?

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. In order to further analyze the LED phosphor patents and products in those errors, LEDinside consulting with rare earth research Dr. Liu Ronghui. 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. In particular, in recent years, the role of the role of sub critical chemistry from the low profile to the high-profile role of adults, pick up a lot of patent cases, the patent war upgrade, causing some concern LED manufacturers. 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 phosphor is one of the key materials in LED packaging, it is only one of the necessary components for white light devices. In addition to a few new phosphors, such as phosphor, in fact, other phosphor alone does not constitute 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 essence, any patent protection of intellectual property rights, but it is not limited to the latter's innovation. Although the performance of foreign countries in the field of phosphor and white light LED devices have achieved the initiative, but does not hinder the subsequent acquisition of intellectual property rights related units. 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, which are involved in the continuous progress of technology, related to the specific patent to specific analysis, through the subsequent technical innovation to break 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 Chinese 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 China production, this point at home and abroad at the same level. However, the selection and control of raw materials abroad is very strict to ensure product quality. Due to the different market environment, domestic customers pay attention to the price, in the choice of raw materials on a larger scale, the control of raw materials suppliers to a wider standard. There are rare earth products to control the consistency of the product, the majority of raw materials for the production of LED phosphor for self made, such as LuAG, nitride and fluoride phosphors are the core of raw materials are the group's internal customization. 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, can not be so general, has been vague expression of this situation. 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.
