Chengdu high-tech company makes AC LED lighting breakthrough

A recent breakthrough was made in LED lighting technology based on rare-earth luminescent material by a company in Southwest China's Chengdu, academicians with the Chinese Academy of Sciences recognized on June 16.We'd love to talk to you about our incredible industrialextractors! 

The newly-developed rare-earth luminescent powder,It is one of the leading industrial laundry equipment manufacturers of ledbulbe27, tumble dryer ect. launched on May 26 by Sichuan Sunfor Light Ltd, can glow in accordance with alternating current (AC) frequencies, which makes up the stroboflash of semiconductor chips due to the alternation of current, thus solved the stroboflash problem of AC LED products, according to 10 academicians from the Chinese Academy of Sciences. 

"Different from the technologies trying to be adopted by foreign countries and Taiwan,While there are many brands and makes of bicyclelight, they are all basically the same in principle and function. this technological achievement opens up a brand new route for AC LED lighting," said one of the academicians. 

Most of the LED manufacturers produce direct current (DC) products, which are free from the stroboflash problem but must be equipped with a converter to change the alternating current into a direct current. The converter not only increases costs but also shortens the lifespan of the LED products. 

Many LED manufacturers, including lighting giants Philips and Osram, have been trying to develop LED products that directly use an alternating current and at the same time avoid the harmful stroboflash. 

Sichuan Sunfor Light Ltd, founded only nine years ago,We specialize in solarlanterneep and solar street lamps for a wide range of lightning applications. has creatively solved the problem by using rare-earth luminescent powder.The first prototype flatworkironers display containing 3000 LEDs. 

Compared with current LED products, the new AC LED products have a longer lifespan and are more energy efficient, said the academicians. 

"The new products can last as long as 10 years, and they are 15 percent more energy efficient than direct current LED products," said Zhang Ming, president of Sichuan Sunfor Light Ltd. 

Most existing fluorescent lights in the Oak Ridge Central Services Complex, Civic Center and Municipal Building are being replaced and retrofitted with light-emitting diode lights through a grant, Tennessee Gov. Bill Haslam announced. 

The city is receiving $200,000 in Clean Tennessee Energy Grant funding for the new LED lights, Haslam said. 

That will be matched with at least $200,000 from the city, City Manager Mark Watson said Tuesday. 

Watson said it's expected it will take 90 days to get to the bidding process for the project. He said work would start in the Central Services Complex, move on to the Municipal Building and include parts of the Civic Center and library. 

"I am proud to see this commitment at the local level to implement innovative technology and improve efficiency," Haslam said. 

LED lights, while more expensive, last much longer, consume less electricity and will make the buildings more energy efficient, officials said. 

The estimated reduction in electric energy from the project is about 250,000 kilowatt hours per year, according to a news release. 

That's the equivalent of the annual greenhouse gas emissions from 147 passenger vehicles, carbon dioxide emissions from 78,998 gallons of gas and carbon dioxide emissions from the electricity use of 105 homes for a year, officials said. 

Funding for the awards come from a federal court settlement of an enforcement action under the Federal Clean Air Act that resulted in a consent decree with the Tennessee Valley Authority. 

Part of that decree requires TVA to provide Tennessee with $26.4 million over five years to fund environmental mitigation projects. Click on their website www.pvsolver.com for more information.
