The bright future of LED lighting meets “life and death”

In early August 2011, the NDRC publicly solicited opinions from the China Roadmap for Phase-out of Incandescent Lamps (Consultation Draft). On October 1, 2011, the National Development and Reform Commission and the State Administration for Industry and Commerce jointly issued the "Regarding the gradual ban on imports and sales. The “Announcement on the Lighting of Incandescent Lamps” clearly stipulates that in order to improve energy efficiency, protect the environment, and respond to global climate change, according to “The People's Republic of China on Energy Conservation Law,” it is decided that since October 1, 2012, the import and sales of general lighting incandescent lamps will be banned. . Traditional incandescent lamps once familiar to people will gradually withdraw from the market within five years. Instead, they will be energy-saving lamps that are energy-efficient and environmentally-friendly. The introduction of this policy has made the energy-saving lamp industry in the process of development extremely exciting. Will the traditional light source transform or die in the next five years? Worthy of attention.

Why eliminate incandescent lamps The country vigorously promotes energy-saving lamps. What are the advantages of energy-saving lamps compared to incandescent lamps? Compared with traditional lighting, energy-saving lamps have incomparable advantages, almost integrates the advantages of various traditional light sources, and are applicable to various traditional light sources. Low calorific power, low power consumption (1/8 of incandescent light, 1/2 of fluorescent light), long life (up to tens of thousands of hours, 3 to 10 times higher than conventional lamps), good color development, fast response , no flash frequency, no eye damage, small size, flat package, thin and light products and other advantages. China is a big country in the production and consumption of lighting products. The output of energy-saving lamps and incandescent lamps ranks first in the world.

Everything has a two-sided nature. When the policy was introduced, some people questioned whether 4 watts must be more energy-efficient than 60 watts. Maybe simply replaced with a 4 watt energy-saving lamp, the effect is not necessarily better than the 60-watt incandescent.

According to calculations, China's lighting electricity consumption accounts for about 12% of the total electricity consumption in society. If high-efficiency lighting products are used instead of incandescent lamps, the potential for energy saving and emission reduction is huge. In the home unit, a 60-watt incandescent light bulb produces lighting that can roughly satisfy the family's life, and an 11-watt energy-saving light can satisfy the same lighting, but if it is replaced with a higher-tech LED, it only needs 3.5 watts. Up to 4 watts. One is 4 watts and one is 60 watts. If you replace all incandescent lamps with LEDs, you may only pay 1/15 of the electricity bill. LED light bulbs are still relatively expensive, but their longevity is also very long. They can be used for tens of thousands of hours. In the long course of tens of thousands of hours, a light bulb may save the same amount of coal as a hill.

According to experts, Xu Yongsheng, director of the National Energy Administration’s Electric Power Department, said that “the elimination of backward production capacity will promote the nation’s energy-saving and emission reduction”, saying: “The standard of backward production capacity is a dynamic standard, and it may follow the development of the economy and with the technical level of the industry. The standards for backward production capacity will also be adjusted, but strictly speaking, this standard is more in line with the laws, regulations, and related policies that we have emphasized such as environmental protection, energy conservation, safety, and quality."

According to Xie Ji, deputy director of the Department of Circumstances Division of the National Development and Reform Commission, “China is a major producer and consumer of lighting products. The output of energy-saving lamps and incandescent lamps ranks first in the world. In 2010, the output of incandescent lamps and domestic sales were respectively 3.85 billion and 1.07 billion. The government will strongly encourage the production and promotion of LED lamps, and the National Development and Reform Commission is organizing the drafting of the "12th Five-Year Plan" for the semiconductor lighting industry, and the Ministry of Finance will study and formulate measures to encourage LED promotion in light of the green lighting policy. The output value will be quadrupled."

Xie Zhenhua, deputy director of the National Development and Reform Commission, said: "Lighting energy conservation is an important part of countries around the world in promoting energy conservation and emission reduction and responding to climate change. China is a major producer of lighting products and supplies more than 30% incandescent and 85% energy-saving lamps to the global product market. The phase-out of incandescent lamps will make an important contribution to saving energy and reducing greenhouse gas emissions globally."

Fang Qing, deputy director of the China Energy Conservation Association, said that in recent years, the proportion of energy-saving lamps in China's resident consumer lighting has reached 30% to 50% through publicity and publicity; in government agencies and large public facilities, the proportion has reached 80% ~ 90%, it is expected that by 2015, China will completely eliminate incandescent lamps.

Studies have shown that most incandescent lamps convert 90% of the energy consumed into useless heat, and less than 10% of the energy becomes light. This is very power-consuming. As for the lighting time, the life time of such lights usually does not exceed 1000 hours. To reduce greenhouse gas emissions, the use of incandescent light bulbs will be banned from 2010.

Lighting power in China accounts for about 13% of total electricity consumption in the society. If we replace all the 1.4 billion incandescent lamps in use in China with energy-saving lamps, we can save 48 billion kilowatt-hours of electricity annually, which is equivalent to reducing carbon dioxide emissions by 48 million tons every year. Therefore, reducing and phase-out incandescent lamps is an important issue for energy conservation and emission reduction. Initiatives.

The interpretation of policies and experts is undoubtedly injecting sufficient vitality into the development of the entire LED industry. However, in the eyes of industry experts, there is no small crisis in this boom. “The standard issue is the biggest obstacle to the development of the LED industry at present, especially the lack of standard and standardized standardized optical components and lighting standards. Guangdong Provincial Science and Technology Department once took the lead in promoting LED lighting products in the country,” said Dr. Ruan Shirong of the Guangdong Semiconductor Lighting Industry Co-Innovation Center. Quality benchmarking system and clearly stipulates that the LED demonstration project must use products that have been benchmarked and recommended by the benchmarking system.In August last year, the Provincial Department of Science and Technology took the lead in organizing 21 research institutes and leading companies to jointly establish the Guangdong Provincial Semiconductor Industry Lighting Industry Joint Innovation Center. The center is a link that organizes upstream and downstream industrial chain or complementary technology companies, related universities and research institutes, etc., to jointly overcome a number of core LED key technologies.The current implementation of the LED lighting standard optical component project is the first organization initiated by the Guangdong Province in the country. The major LED lighting industry research projects."
