LED lighting can be long-term energy saving countries start funding program

In 2007, the great improvement of the luminescent properties of solid-state lighting industry has shown that the light emitting diode (LED) lighting is an optional alternative to existing lighting technology, this is not some time in the future, and it is today. One of the key factors that drive people to adopt LED lighting technology is that it can save a lot of energy, as well as long-term reliability.

According to the U.S. Department of energy (DOE) report, the United States 22% of electricity for lighting, equivalent to the output of the 1000 large power plants, with a total value of $55 billion. DOE expects that in no more than 10 years, the efficiency of solid-state lighting will reach 150lm/W (LM / W), equivalent to the efficiency of incandescent lamp 10 ~ 12 times, compact fluorescent lamp of 2 times. If the efficiency of such calculations, assuming that 50% of the lighting fixtures for LED lighting can save the United States by the country's electricity consumption of 6% ~ 7% (a year to save $17 billion). When many people have no doubt that LED lighting can save energy for a long time, in fact, they do not think LED lighting can really save energy today. Of course, the initial purchase price of today's LED lighting lamps may be several times the number of traditional lighting, which limits the use of LED lighting. However, the first installation of the LED lighting shows that the expected energy-saving is true.

Last fall, WAL-MART announced that it will use more than more than and 500 warehouses in the LED lighting system to replace existing systems in cold storage. Wal-Mart Store Inc 66% operating costs for the purchase of electricity, it is estimated that the use of LED lighting in cold storage will save $3 million 800 thousand a year.

In February 2007, Gree and Raleigh, North Carolina, announced the joint launch of the test, installation, in order to promote the application of LED technology in a variety of conventional lighting. The start of the "LED city" (AnnArbor and Toronto subsequently added) showed that there was a "real laboratory" to assess the impact of the city's residents on LED lighting and its impact on the economy and the environment.
