LED phosphor patents and products in those errors

As we all know, the phosphor patent has been an important force in the LED industry, phosphor patent litigation cases on the LED industry had a great impact. In particular, in recent years, Nichia from the role of low-key research to the role of high-profile rights protection, "pick" from a lot of patent cases, the patent war to upgrade, causing some LED manufacturers concerns.

This patent rights war intensified, resulting in a patent infringement is caused by the errors caused by the phosphor, but this is not the case. Although the phosphor as one of the key materials LED packaging, but it is only constitute a white component of the necessary components of the material. In addition to individual new phosphors such as nitrides, in fact, other phosphors alone does not constitute infringement.

In the current patent LED phosphor patent, by obtaining new phosphor composition and structure and application patents, has become an important way to crack foreign patent white devices, and many companies are basically using this approach to contain foreign patents for inventions, but also And achieved certain results.

But the market came out of this patent is no use, no real effect, but not the case. Essentially, any patent protects intellectual property rights, but it does not limit latecomer innovation. Although the performance of foreign phosphor and white LED devices in the field of the initiative, but does not prevent the follow-up of domestic units to obtain intellectual property rights.

For the patent, we want to do is to respect the existing intellectual property rights, but can not talk about intellectual property and discoloration. Any patent has its limitations, the technology involved in the continuous progress, involving specific analysis of specific patents, through the follow-up technological innovation breakthrough existing patent restrictions is possible.

In this regard, there are rare earth Dr. Liu Ronghui said that the individual does not believe that the domestic application of the follow-up patent is useless, even if it is a lower gold content utility model patents, as long as there is application value, enhance product performance, is valuable Of the patent.

From the domestic patent application of the phosphor point of view, in recent years, domestic LED phosphor in the field of patent applications is very active, but also from the original universities and research institutes to apply for patents, and slowly turn enterprises attach importance to patent applications, which enhance Chinese phosphor and even LED devices in the field of patent strength is very important.

First of all, the current market maturity of the YAG system and the 1113 structure nitride red powder phosphor, for the two series of phosphors, domestic equipment manufacturers and domestic phosphor manufacturers after so many years of equipment on the pondering, and abroad there is no big difference, the basic localization of such equipment.

Second, the new phosphor system (such as nitride green powder) on the equipment temperature and pressure put forward higher requirements to meet this type of phosphor equipment, the current domestic from the highest temperature, maximum pressure, and equipment stability With foreign or there are more obvious differences.

Finally, the need for new equipment to meet the new phosphor preparation process phosphor system (such as fluoride system), this new type of equipment at home and abroad are not directly sold manufacturers, which requires the understanding of the process of the phosphor plant, and then with the plant Common development of new equipment, the difficulty is relatively high, and put aside the quality of the problem, which is currently the world to achieve a small number of fluoride production in a few strong R & D strength of the reasons for the enterprise.
