According to the ban on incandescent lamps passed by the US Congress, the United States will stop selling 40-watt and 60-watt incandescent lamps on the market from New Year's Day in 2014. The move aims to promote energy-saving compact fluorescent lamps, LED lights and other bulbs with higher energy efficiency ratios. It is worth noting that China, the European Union, Australia and other countries will also expand the scope of incandescent lamp regulation from the existing industrial field to residential indoor lighting. Compared with incandescent lamp, LED lamp has obvious advantages in energy saving effect; Compared with the traditional one-piece fluorescent energy-saving lamp, LED lamp has more advantages in environmental protection. In addition, energy-saving lamps contain harmful elements such as mercury, which will cause serious pollution to the environment. However, LED lamps do not contain mercury, and their circuit boards are easier to recycle than energy-saving lamps, and their pollution to the environment is much smaller than that of energy-saving lamps. It is understood that the mercury content of each energy-saving lamp is currently 3 ~ About 5 mg, every 1 mg of mercury can pollute 360 tons of water. To sum up, as LED lamps do not contain mercury and can achieve good results in terms of service life and energy saving, the development prospect of LED lamps is promising. According to the new market report of LED Industry, 2012- In 2014, with the gradual fermentation of the banned benefits of incandescent lamps in various regions, LED lamps began to enter the home lighting market. Due to the increase in luminous efficiency and the decline in the price of LED lamps, consumer acceptance has gradually increased, and the share of LED lighting has also increased. 2013, China area Residence Inn lighting market scale will reach 5941 million dollar into up to 36 which LED Residence Inn lighting market scale will reach 814 million dollar growth 96 is expected to accounted for 24. The demand for LED lighting is rapidly increasing, bringing great opportunities to the demand for related rare metal materials. The core material of LED is gallium (Ga)With Arsenic (AS)Phosphorus (P) A luminescent material for semiconductor chips made of indium compounds. Therefore, with the rapid development of LED lighting, the demand for gallium and indium will increase rapidly, and more and more enterprises and individuals will pay attention to indium and gallium, a rare metal. The listing of rare metals indium and gallium on the pan-Asian nonferrous metals exchange gives enterprises and individuals the opportunity to participate in these two rare metals. After the listing of indium and gallium, the trading volume and delivery volume increased rapidly, making the pan-Asian nonferrous metals exchange a large trading market for rare metals indium and gallium.
