According to the incandescent ban passed by the US Congress, the United States will stop selling the best-selling 40-watt and 60-watt incandescent lamps on the New Year's Day in 2014. The move aims to promote energy-efficient compact fluorescent lamps, LED lights and other energy-efficient bulbs. It is worth noting that China, the European Union, Australia and other countries will also expand the regulation of incandescent lamps from the existing industrial fields to residential indoor lighting.
Compared with incandescent lamps, LED lamps have obvious advantages in energy saving effects; compared with traditional integrated fluorescent energy-saving lamps, LED lamps have advantages in environmental protection. In addition, energy-saving lamps contain harmful elements such as mercury, which cause serious pollution to the environment. The LED lamp does not contain mercury, and the recycling of the circuit board is easier than the energy-saving lamp, and the environmental pollution is much smaller than the energy-saving lamp. It is understood that at present, each energy-saving lamp contains about 3 to 5 milligrams of mercury, and every 1 milligram of mercury can contaminate 360 ​​tons of water. In summary, since the LED lamp does not contain mercury and can achieve good results in terms of service life and energy saving, the development prospect of the LED lamp is promising.
The latest market report of the LED industry pointed out that in 2012-2014, with the gradual fermentation of incandescent lamps in various regions, LED lamps began to enter the home lighting market. Because of the increase in luminous efficiency and the decline in the price of LED lamps, consumer acceptance has gradually increased, and LED lighting occupancy has also increased. In 2013, the size of the home lighting market in China will reach 5,941 million US dollars, a growth of 36, of which the LED home lighting market will reach 814 million US dollars, an increase of 96, is expected to account for 24.
The demand for LED lighting is rapidly increasing, bringing huge opportunities to the demand for related rare metal materials. The core material of the LED is a luminescent material of a semiconductor chip made of a compound of gallium (Ga) and arsenic (AS), phosphorus (P), or indium. Therefore, with the rapid development of global LED lighting, it will drive the rapid growth of gallium and indium demand, and will also drive more and more companies and individuals to pay attention to rare metals such as indium and gallium. Rare metal indium and gallium are listed on the Pan-Asian Nonferrous Metals Exchange, giving companies and individuals the opportunity to participate in these two rare metals. After the listing of indium and gallium, the trading volume and settlement volume increased rapidly, making the Pan-Asian Nonferrous Metals Exchange the world's largest trading market for rare metals such as indium and gallium.
