LED lighting industry, rare earth luminescent materials for the love and sorrow

Recently , the same energy-saving light-emitting materials, rare earth fluorescent and LED situation is rainbow night - the latter sales rose , the former sharp contraction . Rare earth luminescent materials market downturn provides an opportunity for the LED grow . From the earth 's semi-annual report of listed companies can also be seen in the market downturn of the state.

China's rare earth trichromatic energy-saving lamps from a single species with an annual output 1,000,000 H-type energy-saving compact fluorescent lamps to today's full range of varieties , styles up to become the world's most complete variety of compact fluorescent lamps Expo Kingdom , various rare Earth fluorescent output has reached more than 30 one hundred million per year , of which 70 to 80 percent of energy-saving compact fluorescent lamps exported to countries around the world . Rare earth prices have rocketed and rapid decline after the maker of rare earth fluorescent lamps with up with an offer down , however, and the magnitude of price increases fast frequent high , gradually shaken the confidence of customers , resulting in orders plummeted. Some manufacturers converting from rare earth fluorescent LED, LED lighting as the proportion of the sun from last year's 10% to 28 %

The large environmental impact , and application of rare earth rare earth industry as a whole forms poor winter , excess , shuffle , restructuring has become a rare earth industry chain optimization and integration and common development keywords. China's rare earth rich in natural resources , including major applications of rare earth energy-saving compact fluorescent lamps from 80 to 90%. Of light rare earth tricolor phosphor powder from 1.2 tons in 1986 to develop an annual 5,500 tons in 2008 , 6,000 tons in 2009 , 2010 and 2011 with 8000 tons to 2012 slashed to 4500 tons , last year's unrest mainly from Europe and the U.S. economic downturn , the global financial crisis and recession in the domestic market , industry, the economy rebounded this year . According to statistics, China's rare earth fluorescent powder production capacity has reached 25,000 tons per year , the situation appears serious surplus production . " Although this year in June , July rare earth prices has been warmer, but still not achieve the desired level , resulting in the first half of this year, there are still many enterprises have ceased production of rare earth , you want to digest inventory, but the process is very slow ." With the industry analysis Shi said .

The main result of the application of rare earth products for the energy-saving lamps , energy-saving lamp enterprises so that enterprises of rare earth has a deep influence. As the international financial crisis , energy-saving compact fluorescent rare earth export orders fell 30%. China Guangdong Zhongshan Guzhen these lighting fixtures , lighting products distribution center for the pursuit of low-cost, low-quality optoelectronic and competing prices will impact the rare earth enterprises orderly competition ; OEM OEM business is also diminishing multinational buyers for their product acquisition price , but also energy-saving fluorescent light rare earth industry is always in the era of little profit .

Rare is the functional material , the source of strategic materials , light and color of the wizard, enhanced rare earth deep processing is a priority, the system can be in the original light lamp enterprises with rare earth trichromatic phosphors on the basis of further enhancing light rare earth phosphors optical characteristics and physical and chemical properties, reducing the synthesis process phosphor rare earth usage , improve phosphors post-processing techniques . Qualified enterprises can use to accompany the mixed powder monochrome points since production technology , process optimization system of lights , reduce the amount of powder used , optimal allocation without recovery powder, formulated waste toner recycling rules, improve the utilization of the powder .
