shipments growing to 798 metric tons in 2019 from about 523 metric tons in 2014.
This is according to a new report titled, “ LED Phosphors Markerts-2014,” from NanoMarkets, an industry analysis firm.
The report says that despite this growth, Chinese competition and the fall in rare earth prices are hitting phosphor prices hard. As a result, the phosphor market will reach just $442 million ($US) in revenue in 2019 compared with $353 million in 2014.
Almost the entire phosphor value chain is now located in China including raw materials supply, LED manufacture and a major share of the end-user market. Chinese phosphor suppliers have become notorious as low-cost suppliers and this has helped fuel a worldwide phosphor price war.
While NanoMarkets believes these trends will continue to hurt margins in the LED phosphor space, there remain significant opportunities for phosphor makers.
Although only a $51 million business today, the general illumination market will consume $171 million in phosphors in 2019 and around $250 million in 2021.
This will make it the largest segment of the LED phosphors market; bigger than backlighting market which currently dominates LED phosphor sales. One reason for this market expansion is that LEDs are now dropping to a point where they can actively compete with CFLs for the general illumination dollar. Some countries may miss the CFL phase of the evolution of solid-state lighting altogether and move straight from incandescent bulbs to LEDs.
Nitride and oxynitride phosphors are also expected to grow fast, almost quadrupling in volume shipments from 2014 to reach 179 metric tons in 2019, with 313 metric tons shipped in 2021.
Nitride phosphors will enjoy this strong growth because they offer the market improved durability, brightness and a good colour rendering index (CRI). These are attractive features in the general illumination market in which LEDs still perform poorly in comparison to the traditional incandescent bulb.
Companies discussed in this report include: ATMI, Beijing Yuji, Cree, Denka, Epistar, Dow Electronic Materials, eTiger, GE, Intematix, Mitsubishi Chemical Holdings, Nichia, Optiled, Osram, Samsung, Seoul Semiconductor, Sony, Toyoda Gosei and TSMS Solid State Lighting
Intematix Corporation has announced that U.S. patent No 8,597,545 was issued on December 3rd 2013 by the United States Patent and Trademark Office.
“This patent confirms XR red nitride phosphor as a proprietary Intematix innovation moving LED lighting to higher colour quality and reliability,” says Yi-Qun Li, Chief Technology Officer for Intematix. “We look forward to working with our customers on the next generation of LEDs with full spectrum performance and long lifetimes.”
Red nitride phosphors play a central role in extending the colour range of LED applications like general lighting and displays including TVs, monitors and tablets.
Intematix says its red nitrides combined with GAL green phosphors, arrangements covered by the company’s previously issued patents, enable colour rendering up to 98 CRI.
The XR red nitride also has colour stability with less than perceptible 2SDCM measured colour shift in accelerated aging testing.
