The highly anticipated Shanghai World Expo is in full swing. The energy conservation and environmental protection advocated at the World Expo has become the focus of attention, especially the large number of LED lighting technologies, making this emerging industry the vane of the lighting market.
Lighting is used every day by thousands of households. LED lighting has obvious advantages such as long life, high luminous efficiency and power saving. Nanchang is China's first semiconductor lighting engineering industrialization base. I can find in the market that although it is widely used in some public places, LED lighting technology is still a fog in the hearts of ordinary people.
On the 17th, the author was informed that although there is no national standard and industry standard for LED lighting, the unified standard of LED lighting technology in Jiangxi Province has been rushed out, and will be announced soon. The LED lighting market after the standard announcement is expected to be well developed.
<phenomenon> ordinary citizens do not know LED
The giant LED screen at the opening ceremony of the Expo and the 1,700 LED lighting systems of the Expo Park are amazingly impressive. Many people know that this new lighting technology saves at least 60% of electricity compared to traditional lighting. However, the aesthetic and affordable LED lighting is in a difficult position in the general consumer market.
In the past few days, I have visited the Nanchang lighting market and found that most consumers do not know what LEDs are. Most household bulbs and lamps use traditional lighting technologies such as fluorescent lamps and fluorescent lamps. Because of the government subsidy factor, many energy-saving lamps issued by the community are also very popular. Many citizens mistakenly think that it is LED. In fact, it is just an ordinary energy-saving lamp, not an LED lamp using semiconductor lighting technology. In addition, in order to increase sales, many ordinary fluorescent lamps, energy-saving lamps, also in the name of LED lights when selling, flicker consumers.
<Cause> High price and no uniform standard
LED is the abbreviation of English "Light Emitting Diode", its basic structure is an electroluminescent semiconductor material. In the past two years, with the favorable national energy conservation and environmental protection policies, it is getting more and more attention from the market. However, due to high prices and no uniform standards, the LED market has formed a melee situation, and consumers are in the fog.
According to industry insiders, although the country vigorously advocates energy-saving emission reduction and low-carbon economy, Jiangxi Province also listed semiconductor lighting as one of the top ten strategic emerging industries this year. However, there is no national standard for LED lighting technology in China. Industry standards, Jiangxi Province also has no local standards, which makes the LEDs of various brands on the market lack persuasiveness to consumers.
In addition, the high price of LED lights also makes the market share quite limited. The author visited in the market and found that most of the LED lights are more than 10 times the price of ordinary fluorescent lamps. For example, the 10 watts and 0.6 meters of lamps used by many households are 148 yuan. The luminous efficiency of LED fluorescent lamps is equivalent to 21 watts. Fluorescent lamps, but the price is 10 times that of ordinary fluorescent lamps, and is about 5 times the price of mainstream high-efficiency energy-saving lamps on the market. Similarly, the price of 5 watt LED bulbs on the market is as high as 105 yuan, which is equivalent to 20 times that of ordinary bulbs, which is equivalent to about 5 times that of energy-saving lamps. According to industry insiders, the high price is the main reason why consumers are difficult to accept LED lighting and other household lighting.
<Advantages> Long life and special power saving
But in fact, LED lights not only have an aesthetic effect, but more importantly, they have a long life and are extremely energy efficient.
According to industry analysts, the life of an LED fluorescent lamp can reach 50,000 hours, while the life of a fluorescent lamp is usually only 3,000 hours (some domestic fluorescent lamps have a lifetime of only 300 hours). In general, the same power lamp, LED lamp is more than 10 times the life of ordinary fluorescent lamps, saving more than 50%. The study found that the electricity cost of LED lights during use far exceeds the cost of purchasing it.
According to an expert who participated in the development of LED lighting standards in Jiangxi Province, at present, LED light efficiency has been higher than traditional lighting and display light sources, showing superior energy-saving effects, such as energy-saving effects in special lighting fields such as traffic signals and landscape lighting. More than 80%; compared with traditional lamps, functional lighting, such as LED road lighting can save more than 30%, tunnel lighting can save 40%. At present, domestic power LED chips have been applied in some of the road lighting, indoor downlights and spotlights. Through the integration of optical design, heat dissipation, driving and other technologies, the indoor and outdoor functional lighting fixtures have a luminous efficacy of more than 80lm/W (professional terminology, the light per watt can be provided, the higher the value, the better the light effect).
For example, the authoritative expert in LED lighting technology in Jiangxi Province said that the 60-watt incandescent lamp has a life of only 1000 hours, a luminous efficiency of 12 lm/W, and a total power consumption of 1505 degrees. A 15 watt fluorescent lamp has a life span of 6000 to 8000 hours. The efficiency has reached 50lm/W, and the total power consumption is only 327 degrees. Under the current LED technology, the 8-watt LED lamp can last for 30,000 hours, the luminous efficiency is 75lm/W, and the total power consumption is only 240 degrees. By 2015, performance can be doubled again.
<Nanchang>The government strongly supports energy-saving lighting
In fact, this emerging industry, Nanchang City has long been in the forefront of the market. According to the author's understanding, Nanchang became one of the first four semiconductor lighting engineering industrialization bases in China as early as 2004. This also makes the most widely used LED lighting in Nanchang, such as Nanchang's own brand, such as the listed company Lianchuang. Optoelectronics and high-tech enterprises Jingneng Optoelectronics, etc., products are exported to Europe and the United States.
Last year, Nanchang City launched the renovation of LED street lights for Yangming Road, Ziyang Avenue, Minjiang Middle Avenue and Bayi Bridge. A total of 939 åŠå¯¼ä½“ of semiconductor lighting street lamps were installed throughout the year. At the same time, LED street lights were also installed or replaced in sections such as the section of Lushan South Avenue in the Economic Development Zone and the northern section of Fusheng Road in the Xihu District. The person in charge of the Nanchang Street Light Management Office said that as of now, there are more than 1,500 LED street lights in Nanchang. The Nanchang Municipal Government has stated that in 2010, the city plans to add 10,000 semiconductor lighting street lamps.
The relevant person in charge of Nanchang also said through the media that in addition to the street lights, the LED will also shine on the landscape lights. This year, the city will also strive to complete the landscape lighting of the façade of the Linjiang building on the street, and transform the semiconductor lighting of more than ten roads and thousands of landscape belts to give full play to the environmental protection and energy saving advantages of semiconductor lighting products.
<Fracture> Local standards are coming out
Government support is important, and market selling is the key. According to industry insiders, the high price plaguing the LED lighting market is expected to gradually decrease as competition is fierce and technology is updated. It is imperative to formulate uniform standards as soon as possible. The author was informed on the 17th that the current LED local standards in Jiangxi Province are in the process of being elaborated and will be released soon.
It is understood that in order to promote the healthy development of the emerging industry and regulate the market, the Nanchang Quality and Technical Supervision Bureau has proposed the work requirements for the development of LED lighting sources "LED fluorescent lamps" and "LED bulbs" in Jiangxi Province, which are currently being formulated.
These two standards will mainly cover important indicators such as electrical safety, photoelectric performance, reliability, and energy conservation evaluation. They can comprehensively evaluate the energy saving effect, longevity, luminous efficiency, and environmental protection index of LED lighting products.
It is reported that the Jiangxi Provincial Bureau of Quality and Technical Supervision has organized relevant experts to review these two local standards, and has been unanimously approved by relevant experts, and has now entered the approval process. According to industry insiders, the local standards of Jiangxi Province were introduced before the national standards, which not only facilitated the rapid development of the LED industry in Jiangxi Province, but also significantly promoted the LED lighting market in the province.
