LED approached ordinary people have to lower the value of the home

To say what was the most beautiful Expo Park in Shanghai, has been to believe that people would say is the night. Indeed, the night of Shanghai Expo Park can be said to be a LED light source to create a dream world. With the theme of "Better City, better life", a new generation of light source, which is more energy efficient and more environmentally friendly, the LED light source has been fully displayed on the Expo stage. Many people may ask, how can such a beautiful LED light source be used to decorate our small home?

Compared to energy-saving lamps, LED no mercury pollution

The application of LED technology in the light is not no tungsten lamp, light emitting device, can be as long as through a special chip to convert electrical energy into light energy as a new lighting technology, LED because of its energy saving and environmental protection, long service life, quick start is generally optimistic. Especially in Shanghai, World Expo, LED is the most comprehensive display.

Held yesterday by the Nanjing Association for science and technology to host the eighth annual meeting of young scholars, Nanjing lighting society branch, the relevant experts to reporters in detail the characteristics of LED light source. LED light source is more energy efficient, such as a family of 5 Watt LED bulb can replace the energy saving lamp of 11 watts, with a street lamp with a LED watt equivalent to a 250 Watt High Pressure Sodium lamp. Of course, the more important significance lies in environmental protection, energy saving lamps containing mercury, but at present we are recycling of mercury containing waste energy is not very sound. Once the treatment is not good, Mercury will certainly pollute our soil and groundwater, and this pollution is a long time, will affect the future generations. Nanjing lighting Society Secretary General Shen Ru told reporters.

According to Shen's secretary general, the current LED light source in Nanjing municipal engineering is very good, the amount is relatively large. Before last October 1st, the transformation of the five middle road, basically all of the landscape lighting using LED light source, the first half of this year has been all through the acceptance. The overall renovation has been completed, including the transformation of the Xuanwu Lake will do Longpan Road, you will see all of the light source is LED. It was calculated, Nanjing existing more than 160 thousand high-pressure sodium lamp, if every street lamp hourly power consumption of 0.5 kwh, the city's street lighting power at about 320 million kwh. If all the LED street lights, at least 160 million kwh electricity saving, coal saving more than 50 million tons.

The price is a little high, difficult to promote LED

Although LED has advantages such as light, although the LED lamp in the limelight in World Expo, but the LED lamp has long promotion is not satisfactory, in the city of Nanjing in addition to a number of municipal engineering, but also very few families can use this new type of light source. The reason is the core technology in the hands of foreigners, resulting in high prices.

According to reports, with the past in the global structure of China's IT industry chain similar to the global industrial chain in the LED, Chinese enterprises are still in the middle and lower reaches of the industry. And in the composition of the entire LED industry chain, LED epitaxial chips and chips accounted for about 70% of the industry's profits, LED packaging accounted for 10%-20%, LED applications accounted for 10%-20%. More than 70% of China's LED industry in the middle and lower reaches, is the thinnest part of the profits. LED upstream core technology and the vast majority of patents are in the hands of others. Shen Ru secretary general told reporters that the current domestic LED epitaxial materials, chips in the low - based, more than 80% of the power LED chips, devices rely on imports. Even more worrying is that, due to a considerable portion of China's LED application companies do not pay royalties, which makes its products in overseas markets at any time facing the risk of infringement.

In addition, the current domestic LED manufacturers will focus on the market in the construction of landscape lighting, large screen display, traffic lights and other fields, resulting in the lack of product development for ordinary people. Indeed, the current LED product itself has some problems, including color index and other traditional light sources and some gaps. In other words, it has a very high light efficiency, can be used, but comfort, light environment with the traditional light than there are some gaps. In addition to its supporting product research and development, supporting lamps, electric drive part of these there are some areas need to be improved, on the whole, these two aspects of the LED further restrictions.

Price must fall in order to enter the people's home

The general manager has long been engaged in LED engineering Neo-Neon Holdings Limited Jiangsu branch Zhou Ye told reporters that at present in our country, the architectural landscape is the largest LED application areas, but the most potential or Jiezhuang market, after all China population there. LED want to enter the home improvement market, the most urgent thing to do is to lower the price. "Zhou Ye calculations, the general energy-saving lamp life is 6000 hours, and the LED lamp is 50000 hours and the relationship is almost 8 times, so if the price of LED lights control in the following 8 times, there must be a considerable number of people accept.

3 years ago, the factory price of 40 watts of LED is about $300, and now most of the products priced between 140-160 yuan. On the basis of price cuts, the past 5-6 lumens of the product has now been upgraded to 7 lumens (product quality improvement), it can be said that the price of LED lighting products decreased significantly. Zhou Ye also told reporters that although LED's core technology and patents are mostly in the hands of others, but domestic enterprises have not given up in this area of research in recent years has made some achievements. Before 2002, the domestic LED chip is completely dependent on imports, in 2006 the domestic demand for LED chips 66 billion, imported 37 billion, domestic
