Road lighting systems, night landscape lighting systems, etc. are all indispensable important infrastructure. With the acceleration of urbanization, more and more cities and even more and more towns, in addition to the high functional requirements of street lights and landscape lights, also attach great importance to their decorative lighting. However, while the urban lighting system brings convenience to people's lives, it also consumes a lot of electric energy. Urbanization brings not only greater demand for lighting, but also greater pressure. Energy saving, low carbon, green lighting, sustainable lighting... all are the direction that the lighting industry is looking for today.

On May 23 this year, the Guangdong Provincial People's Government issued the "Guangdong Province Implementation Plan for the Promotion and Use of LED Lighting Products" (hereinafter referred to as the "Plan"), which is a comprehensive strategic deployment for promoting energy conservation and emission reduction, and driving the development of LED lighting and related industries. According to the implementation plan of the plan, Guangdong Province will popularize LED lighting in the field of public lighting within three years.

Turn the concept of green lighting into action

As green lighting, LED lighting has no doubt about its energy saving, and it is also one of the general directions of the development of the lighting industry, and it is the common dream of the industry. The introduction of this policy is undoubtedly the gospel of the LED industry, bringing hope of an oasis to the hungry industry. Since the announcement of the plan, Dongguan, Shenzhen, Taishan, Shantou, Zhongshan and even the east, west and north of Guangdong have successively introduced plans to vigorously promote LED lighting.

Tang Guoqing, general manager of CREE's Chinese market, said in an interview with a reporter from Aladdin Lighting News Network that this policy is a double-edged sword. Under the premise, there is no doubt that Guangdong, as an LED industry base, this move is in line with the country's policies and actions. Undoubtedly, it is a big boost and stimulant for the entire domestic LED industry, especially for enterprises. "Guangdong Province, as the first province in the country to implement this policy, dares to innovate, take the lead, and create opportunities to promote the development of LED lighting. The Guangdong provincial government has a long-term vision. I think this idea and approach are very innovative." He said.

Green lighting, especially LED lighting, is the prospect of future lighting. Promotion is a necessary way for development. The promotion of green lighting requires practical actions to be realized. Tang Guoqing believes that the new LED policy of Guangdong Province has embodied the concept of green lighting and green lighting city. , For the semiconductor lighting industry, it is also a great promotion, which can truly apply environmentally friendly products to practical applications, giving traditional lighting companies an opportunity to transform and replace. Li Shiyi, managing director of CREE (CREE) Hong Kong Co., Ltd., also expressed his approval of Guangdong's move: "I am very supportive of Guangdong Province's initiative to vigorously promote LED lighting. The country benefits the people. This move of the Guangdong provincial government can be described as vigorous and practical."

The data confirms that the LED energy saving effect is remarkable

Guangdong took the lead as "the first person to eat crabs", which naturally caused a variety of voices and waves in the industry. This new policy, the voice of opposition is more prominent, the main reason is that the current development of LED lighting technology is not enough to inherit the concern of the "big rule" of public lighting. Despite this, relevant experts from the Guangdong Provincial Department of Science and Technology said that the prejudice against LED lighting is untenable, and used data to argue that the power saving rate of LED demonstration projects that have been implemented has reached or exceeded 50%.

"Guangdong introduced this policy, the meaning of encouragement is greater than the actual meaning, everything must be tried at the beginning; if it succeeds, it can be implemented on a large scale; One of the main forces in the production of lamps and lanterns, it is inevitable to take this step. Many LED companies have encountered difficulties in their survival. Without the promotion of the government, there will be a crisis, so the current launch of this policy is like a "rescue of the market". "Beijing Halsai Lighting Wang Peixing, manager of the design department of Technology Co., Ltd.

In the new policy plan issued in Guangdong, it is shown that through the implementation of the promotion and application project, more than 50% of lighting energy saving under the same caliber will be achieved. Previously, media reported that in the renovation project of Chancheng District, Foshan City, more than 11,000 high-power LED lamps were newly installed, which saved more than 10 million kWh of electricity per year compared with high-pressure sodium lamps, and the electricity saving rate reached 62%, saving more than 8.9 million yuan in electricity bills. Equivalent to saving 3,915 tons of standard coal, reducing carbon dioxide emissions by 10,257 tons and sulfur dioxide by 117 tons, which is equivalent to adding 598 mu of forest every year.

In addition, in the LED street lamp and tunnel lamp lighting project of Shenzhen Expressway, the project cost of high-pressure sodium lamp and LED tunnel lamp respectively selected for the same tunnel lighting project was compared. The results show that if high-pressure sodium lamps are used, 530 high-pressure sodium lamps of 100 kWh are required per kilometer of tunnels, the total investment of lamps is 769,000 yuan, and the investment of power distribution lines is 167,000 yuan, and the total investment is 936,000 yuan; Under the premise of the same lighting standard, only 286 LED tunnel lights are needed, and the total investment in lamps and lanterns has dropped by 44% compared with the use of high-pressure sodium lamps, and the investment in distribution lines has dropped by 50%. In addition, with the savings of 1.017 million yuan in electricity bills and 212,000 yuan in lamp maintenance expenses during the LED operating life, the entire new lighting project from investment to later operating expenses, compared to the same period last year, high-pressure sodium lamps save 1.742 million yuan.

Promote the wide application of LED lighting with point and surface

It is well known that LED lighting is energy-saving, but currently it is mostly used in outdoor and public area lighting, indoor lighting, especially home lighting has not been popularized, so this market can be said to be a potential stock at present, how can we bring LED light source to ordinary people Home is a headache for countless businesses. According to a report released by the relevant departments of Guangdong Province, LED companies in the United States, Japan and Europe own more than 80% of the core technology patents of LED chips, while domestic similar companies own less than 10% of similar patents. For a long time, the core basic technologies of the LED upstream epitaxial wafer and chip market have been monopolized by several foreign industrial giants, occupying about 70% of the entire industrial chain, which also makes the structure of my country's LED industrial chain very unreasonable, and the pressure falls heavily on LEDs on the shoulders of the company.

According to the new LED promotion policy, the promotion of non-public lighting fields will be accelerated through the guidance of comprehensive LED lighting social demonstration projects such as indoor lighting and the promotion of related supporting policies, driven by the popularization of LED lighting in the public lighting field for three years; In the arrangement of application demonstration projects, fully take into account the reality of rural areas, and arrange a certain proportion of rural areas to join demonstration projects, guide and drive the application of LED lighting products to cover rural areas, advocate and promote the gradual promotion and application of LED lighting products in various fields of society, and ultimately speed up the application of LED lighting products. Popularize social LED lighting.

Relevant data shows that by the end of 2011, Guangdong Province LED lighting demonstration projects have promoted and applied 250,000 LED street lamps, driving the annual output value of the LED lighting industry to reach 151.5 billion yuan, ranking first in the country. The government directly supports the "faltering" LED lighting industry with "hands", and further promotes the wide application of LED lighting in indoor and other fields by popularizing the application in the field of public lighting.

In this regard, Wang Xiu, R&D Director of Tianbao Group International Co., Ltd. believes that Guangdong's vigorous promotion of LED lighting can accelerate the promotion of LED lighting applications. This demonstration role will gradually be accepted by the common people, thus laying a solid foundation for the popularization of indoor LED lighting in the future. Based on the foundation, it has guided the direction of domestic LED lamps and supporting industries, and directed their energy to the public lighting field of the existing government in the early stage, reducing the financial pressure of manufacturers.

Can adopt the EMC model or learn from the "American approach"

There is such a foreign proverb: "Any coin has two sides". It is true that there are both positive and negative sides in everything. The fact that the introduction of the Guangdong New Deal has caused a storm of public opinion tells us that this policy is not absolutely perfect. While it brings hope to the industry, it also brings the industry more space for thinking and discussion.

Now that many regions have begun to implement and implement lighting energy-saving transformation, how should the policy be better implemented? On August 24th in Chancheng District, Foshan City, Guangdong Province, the "Foshan City LED Lighting Product Promotion and Application and LED Industry Technology Roadmap Released" At the site of the exchange meeting, Lei Ming, general manager of the energy-saving lighting company of Nanhai Power Grid Comprehensive Energy Co., Ltd., introduced the "operation and operation mode of the energy management project of the LED street light transformation contract". He said that since EMC is a professional energy-saving company responsible for energy management It is implemented by service companies, so it can provide more professional and systematic energy-saving technologies than general technical institutions. The energy-saving rate of EMC projects is generally 40%-60%, and the highest is 70%. EMC mode energy saving is more professional.

The EMC model is not unfamiliar to those in the LED lighting industry. It is a market-oriented energy-saving mechanism that pays the cost of energy-saving projects with reduced energy costs. Zhao Shengxin, the chief designer of Shenzhen Shangzhu Art Design Co., Ltd., also advocates the use of the EMC model. He said: "The contract energy management (EMC) operation model should be a good operation model, but it should be more pragmatic and operational in market operation. In the process of implementation, the source of policy implementation should be transparent and fair. Power rent-seeking and engineering fraud should be avoided. In terms of assessment, both energy-saving indicators and economic efficiency should be measured, and more emphasis should be placed on long-term assessment. We should not only look at the energy saving and the effect of one year in the data, but also pay attention to the effect after a few years.”

In addition, Guo Wenjun, director of the Lighting Planning Office of the Urban Planning Institute of the China Urban Construction Research Institute, expressed his views to the reporter of Aladdin Lighting News: Guangdong Province may wish to learn from the "American method" when promoting the popularization of LED lighting. "Chicago No. 2 Road, California, USA, in promoting the use of LED road lighting, once closed a 3-kilometer road, allowing many LED lighting companies in the United States to put their products into it, let people experience it, collect feedback, and then According to the expert group and relevant personnel of LED enterprises, collect and sort out. Then formulate relevant standards based on this and use them to screen products. The actual time is more than half a year." He said that this is just a phenomenon and case, but he hopes to be able to strictly implement this case. LED promotion policies should not be impetuous and push for push; lighting design is still "people-oriented", and the government's general promotion of LED lighting should not leave "people-oriented".

"Practice is the only criterion for testing the truth. LED promotion should strip away the gorgeous coat, really start with the core technology, improve product quality, and use it well is really good." Zhao Shengxin said.

Conclusion: The introduction of a policy has its reasons for its existence. The world is not perfect. Of course it exists, but it may be lacking. The judge needs to correct its mentality and use a rational heart and a calm heart to see its existence clearly. necessity and advantage. Guangdong has popularized the application of LED in the field of public lighting within three years. When I carefully read the policy document, I found that the purpose and significance of the policy is far more than "replace the high-pressure sodium lamp and install the LED lamp".

As some interviewees said, the introduction of this policy in Guangdong is more meaningful than practical. Everything must be tried at the beginning; if it is successful, it can be implemented on a large scale, and if it fails, it can be summed up. Guangdong, as the "first person to eat crabs", vigorously promotes LED lighting, which can accelerate the promotion of LED lighting applications. This demonstration role will surely be gradually accepted by the common people, thus laying a solid foundation for the popularization of indoor LED lighting in the future. .

Of course, everything has multiple sides. From an objective point of view, the current application of LED lighting is indeed not only good or bad, but a question of whether there are more advantages or more disadvantages. Weighing the pros and cons, Guangdong Pupu LED has more advantages than disadvantages for the development of the industry. Its imperfections can be continuously improved in the implementation details in the future, and strive to better meet the needs of practical applications and create people's lives.
