When energy-saving meets high-priced LED lights applause

As a new generation of light sources that are free from mercury pollution, energy saving and environmental protection, in recent years, national and local governments at all levels have vigorously promoted LED lighting, and various policies have benefited frequently. The State Council executive meeting held recently decided to arrange financial subsidies of 36.3 billion yuan to promote the sales of energy-saving home appliances and other products, including arranging for 2.2 billion yuan to support the promotion of energy-saving lamps and LED lights.

All walks of life also paid high attention to LED lighting. Recently held seminars, exhibitions, etc., have conducted in-depth discussions on the development, status, and direction of LED lights.

What about the current promotion of LED lights? Can it become the dominant lighting market? In practical applications, what kind of bottleneck is encountered in the promotion of LED lights? With these questions, the reporter conducted an in-depth visit.

Policy central local frequent favorable energy-saving account for a gas station In these days, PetroChina Puji Bridge gas station has just converted the shelter lamp from the original metal halide lamp to an LED lamp. When it lights up at night, it is bright and exceptionally bright.

"Since the previous year, we have been piloting the Beijing Cheung Petrol Station in Beichen District to promote LED lighting." Relevant person in charge of the sales division of PetroChina Tianjin told the reporter that replacing metal halide lamps with LED lamps not only improved lighting, And it also saves electricity. The specific amount of electricity that can be saved, the responsible person calculated an account for the reporter (please see chart 1). After the renovation of the gas station shelter lamp, the overall lighting brightness was 5 times that of the original, and the amount of electricity was only a quarter of the original. It was also a case where the dimming of the refueling area was difficult to recognize and the monitoring facilities could not play its role.

A relevant person in charge of a large-scale LED lighting manufacturer in the city calculated for the reporter. Taking the installation of LED lamps at gas stations as an example, the price of each LED lamp is 3,800 yuan, among which, the power supply, cooling system and chips that make up the core components of LED lamps About 70% of the total price, the cost of accessories and manual installation for the three-year warranty of the core parts accounted for about 10%. These are hard expenses. “Because the current market is still in the cultivation period, people do not have enough knowledge of LED lights and the degree of recognition is low, resulting in low overall output of production companies. When we promote, we mainly calculate long-term economic accounts for our customers. With the increase in market demand and the increase in output, the unit price may well be equal to the energy-saving lamp."

Relevant person in charge of the sales division of PetroChina Tianjin City Express Co., Ltd. expressed understanding of the high price of LED lights. She believes that despite the large investment in the conversion of metal halide lamps into LED lights, it is still worthwhile to calculate them for a long time. , One year and four months can be recovered investment.

Where are the LED lights?

An industry source told reporters that LED lamps use high-brightness white light-emitting diode light source, its energy-saving effect and a long service life has been affirmed, pollution-free features are also more recognized by the World Environmental Organization.

According to reports, LED light DC drive, ultra-low power consumption, electro-optic power conversion is close to 100%, the same lighting effect than the traditional light source energy saving more than 70%. The LED light source is called a longevity light, meaning a never-extinguishing light. Solid cold light source, epoxy resin encapsulated, there is no loose part of the lamp body, there is no weakness of the filament light-emitting easy to burn, heat deposition, light decay, and the service life of up to 50,000 to 100,000 hours, longer than the traditional light source life of more than 10 times . In addition, LED is a green light source, there is no ultraviolet and infrared light in the spectrum, low heat, no flicker, no radiation, waste can be recycled, no pollution, no mercury elements, cold light source, can be safely touch, is a typical green Lighting source, better environmental protection effect. Because the LED lighting fixture achieves a 5x power lighting effect with minimal power, there is no rectifier, low voltage, cold light source will not cause fire, and the required wire size is much lower than the current wire specifications for lighting fixtures, and LED lighting fixtures It has a long life, can be repaired, and its subsequent maintenance is also much lower than the current traditional lamps.

Frequent policies favor the rise of LED lighting as a typical symbol of high-tech advancement in the late 20th century, and are recognized as the hope for a new energy-saving light source suitable for green lighting in the 21st century. To this end, many national ministries and governments at all levels have issued a number of policies to promote the application of LED lights.

According to the reporter, in order to support the development of the LED industry, on March 20 and May 7 this year, the country has issued the "2012 Semiconductor Lighting Products Financial Subsidy Promotion Project" and "Semiconductor Lighting Technology Development" Twelfth Five-Year Plan planning".

In the subsidy promotion project documents, the National Development and Reform Commission announced that in 2012 China will spend 40 billion yuan for the purchase of LED street lamps, and provide 30% financial subsidies to users of LED street lamps. In the special plan, it is intended to implement the central financial subsidy policy for semiconductor lighting application products and to support the “Ten Cities Ten Thousand Miles” model cities, and proposes that by 2015, the scale of semiconductor output will reach 500 billion yuan.

In addition, the executive meeting of the State Council held recently decided to arrange financial subsidies of 36.3 billion yuan to promote sales of energy-saving home appliances and other products, including arranging 2.2 billion yuan to support the promotion of energy-saving lamps and LED lights.

LED lights in Tianjin to promote energy-saving emission reduction, effectively guide the healthy and rapid development of semiconductor lighting applications in China, stimulate consumer demand, and promote the industry's core technology research and innovation and innovation capabilities, since 2009, the Ministry of Science and Technology approved the development of 37 cities such as Tianjin "Ten City Ten Thousand Miles" pilot project for semiconductor lighting applications.

The relevant person in charge of the Municipal Science and Technology Commission stated that at present, the city has become one of the cities for demonstration and application of large-scale LED lighting. In the next two years, the city will carry out demonstration of technology application in road lighting projects in the Binhai New Area, lighting in underground parking lots in Tianjin Railway Station, and energy-saving building lighting projects on both sides of the canal. These science and technology application demonstration projects will promote 80,000 LED lighting fixtures.

At present, Tianjin has implemented more than 60 large-scale semiconductor lighting demonstration projects and has used more than 430,000 LED lamps to save about 160 million kWh of electric energy around the city's key developments such as the development of the Binhai New Area, rural new towns, and road lighting. ‖

Among them, the outdoor lighting including street lamps, garden lights, and tunnel lights was 112,000 feet, including 318,000 sets of indoor lighting lamps such as lamps, downlights, spotlights, and flat lamps. As of the end of 2011, the city has built 600 kilometers of LED lighting demonstration roads, indoor lighting demonstration area of ​​2.65 million square meters, a total of 300,000 new application of semiconductor lighting fixtures. Tianjin Semiconductor Lighting Demonstration Project mainly focuses on four modules: LED campus, LED traffic, LED eco-city and LED industrial park. Among them, the LED industrial park module uses 167,000 LED lamps, the LED campus module uses 125,000 LED lamps, the LED traffic module uses 56,000 LED lamps, and the LED eco-city module uses 82,000 LED lamps.

The center of attention of the Cultural Center Grand Theater also uses a new type of high-efficiency LED power-saving lighting fixtures designed and manufactured by the city itself. According to reports, the major lighting locations of the Grand Theater, such as roof lighting roof lighting, back grille lighting hook lamp and the top of the computer room curtain wall tower lamp group all use energy-saving and environmentally friendly LED light sources, a total of 22,800 LED lights. Including roof lamp 4500 盏, sidelights (outer grille) 13000 盏, linear flood light 2000 盏, underwater lights (flexible lights) 2800 盏 and so on.

Can subsidy allow LED to break through?

The national government’s 2.2 billion yuan special subsidies to support energy-saving lamps and LED lamps will be formally introduced in early July. This is one of the initiatives of the State Council to promote the consumption policy of energy-saving appliances and other products.

“The quota for LED energy-saving lamps that this city has applied for financial subsidies this year is 100,000.” Meng Lei, of the Tianjin Energy Conservation Association's Resource Environmental Protection Technology Special Committee, told reporters. Since the bidding price of the national LED lamp manufacturers has not yet come down, how much subsidies will be given by the state finance and the local financial authorities in Tianjin, and no specific plan has yet been issued.

This year, the financial subsidies for LED lights are only for the four major categories of LED spotlights (low power), LED downlights, LED street lights, and LED tunnel lights. However, LED lamps with the largest actual use are not included in the scope of financial subsidies. Industry analysis, which is relatively mature with the former technology, the latter technology is not yet mature.

The financial subsidies provided by the state and local governments are limited to the purchase of lamps produced by LED manufacturing companies that can win bids in bidding activities organized by the state. “The key beneficiaries of subsidies will surely be large-scale LED enterprises with competitiveness.” Meng Lei said, “At least the registered capital is over 50 million yuan and it has national energy conservation certification.”

"The 2.2 billion yuan subsidy will reduce the price of LED lamps, or a drop of 15% to 20%." Meng Lei analysis, financial subsidies will stimulate the scale of production, and scale will certainly pull down the price of the product. In fact, the price of LED lighting industry is changing rapidly, and the price will be lowered once in 3 to 6 months. This year, the price is down by 20% compared with last year.

LED lighting is mainly used in street lights and landscape lights in Tianjin. According to Meng Lei's observation, the application of street lamps is only partially engaged, for example, the Jinghai Development Zone was equipped with LED street lights, and the city's major backbone road bridges were barely used. Meng Lei estimated that the application rate of LED lights in the city's cityscape may reach 10% to 20%. LED lights are even less common among ordinary residents. From the national point of view, the current domestic LED market share in the lighting market is still less than 5%.

Under the circumstances that the initial LED cost was relatively high, it would be difficult to open the market in the short term without the government's financial subsidies and support. Therefore, the guiding role of the subsidy policy should not be underestimated.

When energy-saving meets high prices, the entire society is advocating low-carbon environmental protection. LED lighting has won the top spot with no pollution, green, energy-saving, environmental protection and many other advantages. It will undoubtedly become the biggest competitor of fluorescent energy-saving lamps. It deserves to guide the future development of lighting.

However, the high prices make LED lamps the most intuitive and unacceptable factor in the promotion. Replace incandescent lamps with energy-saving lamps, for the average consumer, has completed a leap in awareness of energy conservation and environmental protection, and further needs to further subvert consumer awareness on another level, especially at this stage of the LED light national standard has not been introduced, consumers For the performance of LED lights is not very clear, do not know how to buy LED lights, the price will become the market leverage, 177 yuan bulbs placed in a few dollars or even a dozen yuan next to the bulb, how to choose, most people may be Do not hesitate to pick up the lower price.

Price is a barrier to the development of LED lighting. When LED lighting can replace fluorescent energy-saving lamps, we can see when LED prices come down. Only with price down, product quality is stable, can we grab the current market dominated by fluorescent energy-saving lamps.
