Since its establishment in 1999, China Industry Fair has gone through a glorious development process. This year is the 11th. It has now developed into the largest, most functional and highest-level exhibition event in China's industrial economy. This year's Industry Fair is one of the important national exhibitions in China after the National Day of the 60th anniversary of the founding of New China and before the opening of the 2010 Shanghai World Expo. As the exclusive network support unit of the 2009 Industry Fair, Dongfang.com will invite guests to participate in the interview program during the exhibition to discuss the current industry fair.
On November 4, 2009 (Wednesday) 10:00-10:30, Tang Guoqing, director of the Semiconductor Lighting Professional Committee of China Lighting Association, and Zhang Xiaofei, CEO of Gaogong LED, visited the chat room of Dongfang.com and introduced you to "City LED Lighting". Products and equipment." Welcome to watch and ask questions!
Moderator : Hello, everyone, we are at the 2009 China International Industry Fair. Today, I would like to invite two guests, the one sitting next to me is Tang Guoqing, Secretary General of the Semiconductor Lighting Professional Committee of China Lighting Association. Welcome.
Tang Guoqing : Good morning, everyone, I am honored to have the opportunity to discuss the LED issue with everyone.
Moderator : This is Zhang Xiaofei, CEO of Gaogong LED.
Zhang Xiaofei : Hello, everyone who cares about LED lighting, everyone!
Moderator : The topic we talked about today is urban LED lighting products and equipment. When it comes to LED, many netizens are no strangers, but first, please tell us what LED is?
Tang Guoqing : Dear friends, please allow me to briefly introduce the main features of LED to everyone. LEDs used to be LEDs in the past, but in the past two years, LEDs have been described as semiconductor lighting because the LED itself is developing very fast. For example, LED itself is simple to use for signage. With the rapid development of LED in these two years, LEDs have been 1 watt to 135 lumens since the second half of the year, and the threshold for LEDs entering the general lighting field has disappeared. For example, a street lamp with a lumen of 80 lumens has reached the illumination. If it is 135 lumens, there are many LED lamps for cars, and the headlights of the car can be made with LEDs. Now we compare LEDs to semiconductor lighting. Everyone knows that the history of light bulbs has a history of more than 130 years. There are changes in energy-saving lamps. The emergence of high-voltage lamps, including the appearance of metal lamps, but the emergence of LEDs in our industry is green lighting. Revolution. Why is it green lighting? The characteristics of LEDs have at least a few very important features: First, they are green. Any kind of light source we used in the past is not completely environmentally friendly, because it contains mercury, it is not very friendly to the environment, and LED is environmentally friendly. We are the people of the earth. Protecting the earth is everyone's responsibility. Especially the whole world is promoting energy conservation and emission reduction. LED is a very good low-carbon product that saves energy and reduces emissions. Our world will be a low carbon world in the future. Therefore, I have listed environmental protection as the first place.
Tang Guoqing : LED is very energy-efficient and power-saving. Where is it reflected? Compared with incandescent lamps, energy saving reaches 80%, and at least 40% energy saving compared with the latest energy-saving lamps. Such a good lamp, if not promoted, there is no reason. In addition, a very important feature, the life is too long, in theory, LED lights can be used for 100,000 hours, but because LED lamps are not only involved in the LED itself, but also related to other power supplies, and other zeros. part. Therefore, the general LED will mention 30,000 hours to 50,000 hours. If a person goes from elementary school to middle school and graduates from college, with a desk lamp, you can accompany the whole process of your study. In China, in Japan, LED bulbs are very popular, especially popular among middle-aged and elderly people. If the LED bulb is installed, the middle-aged person thinks that he can always have such a lamp in his lifetime, and it is not safe to climb up and down. Therefore, LED has these three characteristics, of course, there are many characteristics, for example, it is very small, I have just said 135 lumens, the size is only 3.45 × 3.45, very small lights, but very bright. I think this is a very big advantage.
Moderator : Director Tang has a few words about the characteristics of LED, environmental protection, low energy consumption and long life. LEDs are widely used in many fields, and the previous chat also said that we have been using the Expo since the Olympics. What are the main areas of LED use now? Can you introduce it?
Tang Guoqing : I am very willing to talk about this topic. It is a great honor to give LEDs a very good display stage especially in the 2008 Olympic Games. Today we can talk about why the Olympics left a deep impression on the world? LEDs play a big role. For example, the buildings left by the Olympic Games, such as the water cube of the swimming pool in Beijing, this year's display lighting, in addition to the Olympics, also showed pink lights, why is this shocking effect? Pink is to promote women's health, using high-power LED, provided by American Keli. I am very proud to tell you that the chief designer is the Shanghai-based Guangmaoda Company, which is made by Shanghainese. The product is also provided by Shanghai Keli Company. Therefore, the Water Cube is really the pride of the Shanghainese. Its lighting is changeable, blue is the keynote, and it can be made into multiple colors. I can still tell you very responsibly. Because the lighting is so beautiful, I won the International Lighting Design Award last year. The light is not lit. This is a very typical case.
Tang Guoqing : Secondly, everyone knows that the Chinese red in the Bird's Nest is also Shanghai Red to some extent. Because the lamp is provided by Shanghai, there are three elements inside, one is soft white, the second is amber, and the third is red. The general contractor is Beijing's “Quantity†company. The screen of the opening ceremony of the Olympic Games, including the part of the drawing axis, is represented by LEDs. We often say in the industry that we are very grateful to Zhang Yimou, thank you to Zhang, let LED have this opportunity to show. In other words, LED has done so much effort, and the award is Zhang, we are unknown.
Tang Guoqing : If you pay attention to it, the Pangu market, we call it China's first screen, 3400 square meters, opposite the water cube, is also made by LED, is done by Shenzhen Konka. After the Olympics, the lights at night were made of LEDs, including the large screens displayed in Tiananmen Square. This time, the headlights in the National Games in Shandong are very beautiful, and they are also made of LEDs. So, LEDs are everywhere. Today's laptops in front of us, the backlight from this year, will be a high tide next year, have to be changed to LED, because LED is very environmentally friendly. Therefore, LEDs are almost everywhere. The information I know now, the Shanghai World Expo, the theme pavilion of the Shanghai World Expo, the Shanghai World Expo Center, and the Expo Center have a transparent display of the world's first 700 square meters. It is also produced by a Shanghai company. The world is also the first. In addition, the theme landscape of the theme pavilion is LED. In many other places, there will be LED figures, including its unique role, including signs and pointing lights.
Moderator : I just heard that LEDs are used in large-scale occasions. So, when can LEDs reach the popularity of home lighting? Can Zhang always talk about it.
Zhang Xiaofei : Mr. Tang talked about landscape lighting from streetlights. We used it every day. I will show you a light source on my mobile phone, which is LED. The LED is a very small, 1.4 mm square, but the luminous intensity is very high. LEDs are used in both indoor lighting and commercial lighting in foreign countries. For example, in different chain fast food restaurants, LEDs are used to make food photos more beautiful. Therefore, LED has its unique features in different occasions. I noticed the current electric car, the lighting used now, you noticed that there will be 4 to 6 LED lighting. In fact, LED lighting is really ubiquitous.
Tang Guoqing : I just introduced it to you in the big landscape lighting. The question you just mentioned is very good. When can LEDs enter thousands of households? I would like to tell you a little bit of information. First, I am very proud of being a Chinese. The Chinese government attaches great importance to LED environment-friendly lighting products. Recently, the National Development and Reform Commission has jointly sent a paper to six ministries, including the Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the Ministry of Construction to promote the development of LED in our country. One of them has a hard indicator LED that is moving forward at 30%. Second, landscape lighting, due to the uniqueness of LEDs, requires that 70% of landscape lighting be used before 2015. Functional lighting, which accounts for 20%, is the ordinary light we see now, including the light used by our family, which accounts for 20%. There is also an indicator that backlighting accounts for 50%. Therefore, this indicator is a great encouragement for us. Under this document, I noticed that there is a strong emphasis on core technology and patents. From this perspective, this is an inspiration to us. Shanghai also attaches great importance to it. I know that Yu Zhengsheng, the mayor of Shanghai, and the mayor of Han Zheng and the deputy mayor of Yang Xiong have given instructions on how to develop LEDs in Shanghai. Recently, the Shanghai Economic and Information Committee took the lead, and the National Development and Reform Commission participated in the implementation of the implementation of the accelerated LED development, which for our association, for the industry leaders, for the enterprise is a great encouragement. Without the attention of the government, LED development will not be so fast. Just talking about it in the chat, this industry is very good, to what extent? This financial crisis has given us a lot of inspiration. Throughout the industry, we can proudly say that LEDs have no winter. why? In the case of such a serious financial crisis, there is still a very high growth rate for LEDs. What is this indicating? Because the world is optimistic about the development of LED. At the next speed, I think LED development will be faster.
Zhang Xiaofei : Let me give you an example. Because the "Core" chip is widely used in LEDs, whether it is street lamps or high-power, all the LED chips produced account for a large proportion. This is the conclusion I got from the investigation of the streetlights in the enterprise. Therefore, LED "Cred" chip is too late to supply, this is the general promotion results of Tang.
Moderator : I think that many of the advantages and benefits of LED are obvious. Both the state and Shanghai governments are vigorously accelerating the pace of LED development. Therefore, the LED investment prospects are very good now. I especially want to know what is the basic status of LED in China now?
Tang Guoqing : I will simply talk to you. Just said, the speed of LED development is indeed relatively fast, beyond our expectations. Our country has set up a national semiconductor lighting leading group since 2003, which was also jointly established by several ministries, which is a great promotion for the whole industry. LEDs are developing very fast. First of all, the application lamps in our country are the largest in the world. The leaders of several multinational companies, in his speech or in the instructions, will mention "the focus of accelerating LED development in the Asia-Pacific region". Where is the Asia-Pacific? Asia Pacific is in China. Why is the LED application lamp developing very fast? Because the construction of the entire country is relatively fast, the LED application level is also very fast. As you can see on the road, all the traffic lights are LED lights. All the landscape lights are almost inseparable from LEDs, because you usually don't pay attention and are not connected with LEDs. Like the mobile phone just released by Zhang, the backlight in the mobile phone is LED, and the flash light including the mobile phone camera is LED, but you usually don't pay attention.
Moderator : Now know that it is inseparable from our lives.
Tang Guoqing : The characteristics of our national industry, one is to do LED lighting, and another important point is that people in the lighting industry, who used to do traditional lighting, are now actively involved in lighting. For example, Shanghai’s Yaming is also following LED companies collaborate and this will grow very fast. Shanghai has developed a bit slower on LED road lighting. Shanghai's street lights are considered more cautiously. I hope that Shanghai will learn from Guangzhou and accelerate its pace. Every district in Guangzhou is now rushing to make LED road lighting up. I don't think Shanghai should fall behind, and should add strength and push. Moreover, Shanghai has many good manufacturers in LED manufacturers, such as Shanghai's Yaming, Shanghai's Sans, like street lights and tunnel lights. Therefore, I think Shanghai will have great development in this regard.
