In many cases, the LED higher efficiency can reduce power consumption by up to 88% They also greatly reduces carbon dioxide emissions caused by the lighting and power generation and transmission of electrical energy. The StrategiesUnlimited the co mpany s research, to 2012, total high-brightness white LED lighting market is expected to exceed 50 billion U.S. dollars, and corresponds to 28% in 2009-2012 compound annual growth rate (CAGR). This is just the beginning, because of the commercial / residential lighting market from incandescent, fluorescent and high pressure sodium, high-brightness white LED at the same time continue to accelerate the improvement of LED luminescence efficiency, led light bulbs for home from a commercial point of view, even become more has cost-effectiveness.

LED lighting can make the current global total energy consumption savings of up to 10% according to some calculations, the shift from traditional incandescent and fluorescent. To accelerate efforts to reduce carbon dioxide emissions from electricity generation, the global lighting energy demand is reduced by 10% of the potential This shift has played a gre at role.

What factors support such a huge potential for growth? First of all, this generation of LED luminous efficiency than incandescent, 10 times higher, is more than twice the fluorescent lamps and high pressure sodium (HPS), which greatly reduces the power to provide the required light output (lumens measure) necessary. With the further development of the LED, they rely on the power light-emitting efficiency will continue to improve, and is expected to double within the next few years.

Secondly, in a very environmentally conscious world, LED lighting does not require processing, contact and clear toxic mercury vapor in fluorescent lamps. Today, the cold cathode fluorescent lamp (CCFL) for most residential lighting systems containing up to 5mg of mercury, more lights contain mercury much more!

Third, the incandescent lamp every 1,000 hours need to be replaced, while the fluorescent sustainable use of up to 10,000 hours, compared to the li fe of LEDs over 100,000 hours. In most applications, this enables the LED to be permanently embedded into the final application being without the need for attachment.

Examples include indoor and outdoor commercial and residential lighting, such as street lights, indoor and outdoor industrial lighting, such as power plants and refineries, and other lighting in hazardous environments. 24 hours of uninterrupted operation of some applications (such as refineries), outdoor light fixtures will last up to 11 years, which means they will not require replacement. In addition, LED than several other types of lighting, small and flat-position can be manufactured to very flat form factor, so they can be permanently placed in the internal and external applications.
