In Chengdu Gaoxin West District, 1000-inch LED energy-efficient street lamps are on for the first time on 13 streets. This is the first LED lighting streetlight project officially implemented in Chengdu after the release of the “Ten Cities and Ten Thousand Miles†program at the end of 2008.
Semiconductor light-emitting diode--LED as a new solid-state cold light source, low energy consumption, long life and green environmental protection. It saves more than 55% of electricity compared with traditional high-voltage nano lamps. The life of each lamp is up to 50,000 hours. If it does not turn off the lights for one year, it is equivalent to continuous lighting for nearly 6 years.
But the cost is equally expensive. The LED energy-saving lamps used in Chengdu this time are 6,000 yuan each. It is reported that before the end of 2011, Chengdu plans to install more than 100 million LED street lights.
In early December, Wal-Mart, the world's largest retailer, signed an agreement with CREE in 2009. The two parties agreed that in 2010, Wal-Mart's North American stores (about 650) will use Corey's LED lamps.
Since AC power cord is output of high voltage electric power, there is a risk of electric shock injury, therefore, All the AC power cord must comply with safety standard to produce. AC (Alternating Current) Power cord is to transmit high voltage. It is used to drive machinery or home appliances.
