[Text / high-tech LED Yue Mengdi] The "magic" of the increase in price seems to have followed the LED phosphor for a long time, and there is no sign of dissipating for the time being. As an important auxiliary material for LED packaging, phosphors can only strengthen their competitiveness through continuous technological advancement and performance improvement, and maintain market share.
"The performance improvement of phosphors for white LEDs has entered the bottleneck period, but it is far from over." Liu Ronghui, director of the Rare Earth Luminescent Materials Division, believes that when the price drops and then falls, the research and development strength of Rare Earth will be the company. The greatest guarantee of competitiveness.
In fact, there are a wide range of fluorescent powder products, and the development of aluminate, nitride and fluoride system phosphors can meet the needs of high-quality lighting and display LED devices.
The products used in lighting mainly include yellow YAG of acid salt system, green LuAG, YGG phosphor, and 1113 and 258 phosphors of nitride system. The overall performance of the product is at the leading level in the industry. Among them, the upgraded version of HR-01J2 and HR-02 series nitride red powder launched in 2015 has the same performance as the highest level in foreign countries, and has outstanding advantages such as good color rendering, high R9 value and high bin.
In the field of high-quality wide color gamut display, Rare Earth has pioneered the introduction of high-performance fluoride red phosphors in China and developed the development of nitrogen oxide green powder. "We will continue to introduce new products in the field of full-spectrum lighting, ultra-high power lighting, and wide color gamut display phosphors according to the development trend of semiconductor lighting technology," said Liu Ronghui.
It is undeniable that the degree of homogenization of phosphors is increasing and the profit margin is getting smaller and smaller, but there are still some high-end demands in the market, which are waiting for domestic LED phosphors to be overcome and satisfied.
Liu Ronghui told Gaogong LED that Rare Earth has always insisted on promoting the development of the company with the concept of scientific and technological innovation, and creating value for customers with the spirit of pragmatic cooperation. What technical innovations and product performance breakthroughs will be made in the next year? At the 2015 High-tech LED Annual Meeting, there are research rare earths to discuss with you.
