Academician of the Chinese Academy of Sciences: LED lighting to replace conventional lamps is the inevitable

The famous optics and laser scientist of the Chinese Academy of Sciences Liu Songhao who participated in "Pearl River Science Lecture Hall" on 8^th August 2013 in Guangzhou, said, LED lighting replacing the traditional fixtures is an inevitable trend, hoping the researchers and production units engaging in this regard should take responsibility to promote the development of China's LED industry.

LED's English name is Light Emitting Diode, also known as light-emitting diode, is a semiconductor electronic components can be light.

" The prior character of the LED light is high efficiency, small heat; secondly, its safety factor is high, the required voltage and current is small, it reduces the security risks so that can be used in mining and other dangerous places." Songhao emphasized that now the LED market potential is large, the available low-voltage DC power can be used to supply electricity， the batteries and solar powered can also be adopted, it can also be used in remote mountainous areas and other outdoor lighting where the power is shortage and limited.

In Liu Songhao’s opinion, the unique advantages available to  the LED light  is that as no today's traditional lighting can match.

According to Liu Songhao’s introduction, and countries are increasing the investment of the development of LED industry now, the U.S. Department of Energy issued a "solid-state lighting plan," in 2012，which predicted that 55% of incandescent and fluorescent lamps would be replaced with the LED light in 2013， and South Korea aims to become Asia's largest producer of optoelectronics, 30% of the lighting will be replaced with the LED lighting in 2015.

"Because Beijing successfully promote the use of LED technology during the period of the Olympic Games, making the Chinese LED industry is paid attention to and further developed." Songhao revealed that China's LED industry scale would reach 500 billion yuan by 2015, the white LED luminous efficiency would attain 150 -200 lumens / watt, estimated that annual saving would be 100 billion degrees that can save 350 billion tons of standard coal so that reduce the carbon dioxide, sulfur dioxide and dust emissions by 100 million tons, and the population of 2 million new job-seekers with employment.

He stressed that the Chinese semiconductor lighting "Twelfth Five Year Plan" key tasks is mainly from the basic research, cutting-edge technology research, applied research and common technology platform for building several aspects, the key is to break through the white LED patent barriers.

According to reports, mainland China LED industry mainly in Pearl River Delta, Yangtze River Delta, Fujian Delta and other places. Among them, of the LED output value of the Pearl River Delta in 2012 reached 128 billion yuan, accounting for 42%.

Located in Shenzhen Guangdong which is one of the three major industrial base in the Pearl River Delta , the Lead lighting is always upholding the interests of customers as the core business objectives, having been committing to use the qualified raw materials such as LED driver, shell, chips, heat sinks and improving and innovating the R & D and production team to determine to create the more energy saving LED flood light, LED tunnel light, LED tube light and other LED lighting，browse www.ledclan.com for more detailed and specific features of the LED tube light or take a good look at www.lead-lighting.com for vivid vivid description on the LED light.
