LED is the abbreviation of Light Emitting Diode. It is a kind of semiconductor electronic component that uses solid semiconductor chip as luminescent material. It is known as the revolutionary technology in the 21st century new solid light source era. Compared with traditional lighting products such as incandescent lamps and energy-saving lamps, the advantages of energy saving, environmental protection, long life, instant start, and high color rendering have been widely recognized throughout the world. Regardless of saving energy, reducing greenhouse gas emissions, or reducing environmental pollution, LED as a new type of lighting source has great potential to replace traditional lighting sources, and countries have also set off a wave of promoting LED lighting.
Japan, the United States, the European Union, South Korea and other countries have successively launched national semiconductor lighting plans. As early as 1998, Japan took the lead in launching the 21st century lighting plan. In 2002, the US federal government also launched the National Semiconductor Lighting Research Program, the Next Generation Lighting Project (NGLl). ), push LED lighting. The EU's rainbow program was also launched in July 2000, entrusting six large companies and two universities to promote the application of white light-emitting diodes through EU subsidies. At the same time, South Korea also invested 100 million US dollars in 2004-2008 to implement solid-state lighting plans. China also issued the "12th Five-Year Special Plan for Semiconductor Lighting Technology Development" in 2012, proposing that by the end of the 12th Five-Year Plan, the market share of light-emitting diodes (LEDs) in the general lighting market will reach 30, forming a market scale of 500 billion yuan.
The past 2013 is a year of rapid development of China's LED industry. According to the statistics of the CSA Research Institute, the overall scale of China's semiconductor lighting application in 2013 has reached 206.8 billion yuan, a year-on-year increase of 36. The general lighting market output value of 69.6 billion Yuan, the growth rate of up to 65, the share of the LED application market also increased from 28 in 2012 to 34 in 2013; due to the demand for tablet PCs and the penetration of LED-backlit LCD TVs continue to increase, backlight applications have also maintained Rapid growth, the growth rate is about 35, and the output value reaches 39 billion yuan. In addition, LED automotive lighting, medical, agricultural and other emerging lighting applications have also grown significantly, with a growth rate of more than 25, while optical communications, wearable electronics and applications in aerospace and other fields are also the highlights of LED applications in 2013.
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. At present, based on the wide band gap semiconductor materials gallium nitride (GaN) and indium nitride (InGaN) is one of the most commercially valuable LED lamp materials. In 2013, the output value of China's chip links reached 10.5 billion yuan, an increase of 31.5; the output growth rate was as high as 61, of which the output of GaN chips accounted for 65, while the output of quaternary chips based on InGaAlP chips accounted for 25%. Other chips such as GaAs account for about 10%.
According to experts' prediction, in 2014 China's LED industry will continue its upward trend in 2013, ushered in a new round of growth, and the growth rate is expected to reach 40 or so. The rapid development of global LED lighting will certainly drive the rapid growth of demand for semiconductor metals such as gallium and indium, and will also drive more and more companies and individuals to pay attention to rare metals such as indium and gallium. As the world's largest spot exchange of rare metal and inventories of rare metals such as indium and gallium, the predominance of the Pan-Asian Nonferrous Metals Exchange in the rare metals industry will gradually become prominent.
