Extraction of rare earth materials from LED bulbs in sand

And LED compared to incandescent bulb despite more efficient and longer service life advantages, but the high price is the key to restricting the popularization in common among consumers, the most important reason is the use of LED lamp fluorescent powder in the use of rare earth elements (REEs). Scientists have recently found a replacement for rare earth raw materials, and ultimately reduce the price of LED bulbs in the future.

From the successful development of University of Washington subsidiary LumiSands alternative materials, the use of LED lamps to create the material in imaging tend to be more natural sun light feeling, in addition to the above temperature than the existing bulbs more cold. In addition, the material is extracted from cheap and abundant sand.
