As one of the most representative enterprises in the domestic LED phosphor market, Rare Earth is mainly engaged in the research, development and production of rare earth and related materials, and has a complete industrial chain from rare earth mines to rare earth functional materials. In the field of phosphors, there are nearly 20 Chinese invention patents and 7 foreign invention patents in the United States, Japan, South Korea, etc., and the market share of products has increased rapidly. 
At the 2014 High-tech LED Exhibition, Rare Earth Showcased its high-efficiency, small-grain, high-stability Ga-containing green phosphors, high color rendering, high-efficiency nitride red powder series and remote fluorescent caps. 
He Huaqiang, director of the Rare Earth Domestic Trade Department and general manager of the South China Operation Center, told reporters at the exhibition that the remote fluorescent cap has been applied to the bulb, which can reach Ra96 and has certain advantages in light uniformity.
Dr. Liu Ronghui, director of the Rare Earth Luminescence Division, told the reporter that the Ga-YAG green phosphor brought by this time has the following advantages: the particle size of Ga-containing green powder is D50: 13~16μm±1; accelerated aging (121°C, 2atm, humidity) 100%, 48h) color drift without drift, brightness attenuation <1%, comprehensive performance close to Lu-YAG green powder level. 
In addition, the high-stability nitride red powder has a colorless drift, and has obvious advantages in terms of accelerated aging, brightness decay, color rendering index, and the like.
Liu Ronghui said that when the above two products are matched, the range of Ra of the packaged device is 80-90, and the R9 value can reach up to 90, and has the advantages of low powder consumption and high light efficiency, and solves the Lu-YAG green powder on the market. The price is high, and the narrowing of the nitride half-peak guarantees the light effect and sacrifices the commonality of color rendering (especially the lack of R9).
In the current market of phosphors, in the context of the increasingly competitive price war, many companies have begun to adjust their marketing strategies. A new round of “shuffle†will come in the near future, and Rare Earth will rely on its technology research and development and funding. Strength, what kind of action will be seen in the new round of competition is waiting to be seen. 
Research rare earth: Bringing high-efficiency green, red powder and remote fluorescent caps to the 2014 High-tech LED Exhibition
[Text|High-tech LED reporter Yue Mengdi] Since the second half of 2013, the price of phosphors has entered the downward channel, and the market competition has become increasingly fierce. In 2014, the situation of “incremental increase without income†has not been improved.
