New opportunities for LED lighting: rare metal gallium and indium will benefit

LED is the abbreviation of light emitting diode (LightEmittingDiode), it is the use of solid semiconductor chips as light-emitting materials, known as the twenty-first Century new solid light source of the revolutionary technology". Compared to traditional lighting products, its advantages are obvious. These advantages include energy saving, long life, instantaneous start, high color rendering, etc..

After the candles, kerosene lamp, incandescent lamp, LED lighting will be taking over time.

Europe and the United States and other countries have introduced regulations to eliminate incandescent lamps, incandescent life countdown, but also established the future of LED lighting position.

LED is the abbreviation of light emitting diode (LightEmittingDiode), it is the use of solid semiconductor chips as light-emitting materials, known as the twenty-first Century new solid light source of the revolutionary technology".

Compared to traditional lighting products, its advantages are obvious.

These advantages include energy saving, long life, instantaneous start, high color rendering, etc..

LED lamps can be a good alternative to incandescent lamps, energy-saving lamps, energy saving ratio of up to 90%, life is also the traditional lamps of the 50 times.

The incandescent lamp is electrically heated to the incandescent state, the use of thermal radiation emitted visible light source, will produce a lot of unnecessary heat energy, and LED can directly convert electricity into light, more energy-efficient than incandescent lamps.

In traditional lamps, high efficiency energy-saving lamp light efficiency 50-60lm/W, and the light effect of LED has reached 100lm/W, and the use efficiency of LED lamps is higher than the energy-saving lamps, therefore, the proportion of energy saving up to 60%.

Compared with incandescent lamp, LED lamp has obvious advantages in energy saving effect, compared with the traditional integrated fluorescent energy-saving lamp, LED lamp has more advantages in environmental protection.

In addition, the energy-saving lamps contain mercury and other harmful elements, will have serious environmental pollution.

The LED lamp does not contain mercury, the recycling of its circuit board is easier than the energy saving lamp, and the pollution of the environment is much smaller than that of the energy-saving lamp.

It is understood that at present, each energy-saving lamps containing mercury in the amount of 3~5 mg per 1 mg of mercury, you can pollute the water of 360 tons.

To sum up, as the LED lamp does not contain mercury, and in terms of service life and energy saving can achieve good results, so the prospects for the development of LED lamps are optimistic.

In view of the obvious advantages of LED lamps in lighting, countries are pushing LED lighting applications.

On the one hand is the policy to encourage, on the other hand is to eliminate backward products, clear obstacles, LED lighting is ushering in the development of a good time.

In order to clear the barriers to the popularity of LED lights, the world's major countries have begun to prohibit the use of incandescent lamps.

Japan in 2012 to stop the production and sale of high energy consuming incandescent lamp.

European Union in 2012 to ban the use of incandescent lamp.

Australia and Canada also banned the use of incandescent light bulbs in 2012.

In the prohibition of incandescent lamps at the same time, countries in policy to promote LED lighting.

Japan took the lead in the twenty-first Century lighting program, completed in 2006 to replace the traditional lighting with white light-emitting diode lighting 50%.

The U.S. federal government in 2002 launched the national semiconductor lighting research program, namely the next generation lighting program (NGLl), pushing LED lighting.

In 2003, the European Union launched the "Rainbow plan" to promote the development of high brightness outdoor lighting.

South Korea's solid state lighting program was approved by the government, the government invested $100 million in, the company provides 30% of the matching funds, the goal of the program is the luminous efficiency of up to 80 lumens / watt in 2008.

China also issued the "semiconductor lighting technology development" 12th Five-Year "special plan", put forward to the "12th Five-Year" at the end of the light emitting diode (LED) in the general lighting market share reached 30%, 500 billion yuan industrial scale target.

Thanks to the expansion of production capacity, LED prices, environmental considerations, as well as government subsidies and other factors, more and more consumers choose more efficient LED lights to replace the traditional light bulbs.

DisplaySearch latest report that, in 2013 LED lighting demand will be raised to 33 million, is more than 16 million and 1 times in 2012.

And is expected in 2016 LED lighting demand will reach 90 million, the penetration rate will increase from only 5% in 2012 to 26%.

LED lighting demand is rapidly improving, to bring huge opportunities related to the demand for rare metal materials.

LED is the core material of gallium (Ga) and arsenic (AS), phosphorus (P), indium compounds made of semiconductor chip light-emitting materials.

At present, the wide band gap semiconductor materials based on gallium nitride (GaN) and gallium indium nitride (InGaN) is one of the most commercially valuable LED light material.

The rapid development of global LED lighting, will drive the rapid growth of gallium and indium demand, will drive more and more companies and individuals concerned about the rare metals such as indium and gallium.

Rare metals indium and gallium in the Pan Asian Non-ferrous Metals Exchange listed companies and individuals to get the opportunity to participate in these two rare metals.

After the listing of indium and gallium, trading volume and the rapid increase in the volume, so that the Pan Asian non-ferrous metals exchange has become the world's largest rare metal indium and gallium trading market.
