LED is the preferred type of lamp source in the market

LED is the preferred type of lamp source in the market at present. Compared with traditional incandescent bulbs, LED has better performance and longer service life. However, rare earth elements are used in the fluorescent body of the white luminous LED lamp source. The main function is to emit longer light waves from the LED chip, so that the bulb can emit visible light of full spectrum. The mining and processing of rare earths is quite dangerous. At present, China is a country that provides a considerable amount of rare earths in the world, resulting in rising prices of rare earths, for this reason, the research team led by Professor JingLi from Rutgers University in New Jersey has successfully found an alternative solution for LED lamp sources. The research team has extracted new alloy materials from very cheap and abundant copper iodide, which can replace rare earths as fluorescent bodies for LED lamps. What is important is that this extraction method is simpler and cheaper. In addition, through the adjustment of color and intensity, white light that is warmer and more mixed with blue can be adjusted than the existing LED.
