The next 10 years who will replace incandescent

Incandescent lamp in the use of only 5% of the electricity used for lighting, all of the remaining 95% by the heat consumption. The energy saving lamp can convert 90% of the electric energy into light energy, to achieve the same light effect, the energy consumption of incandescent lamp 1/5, life expectancy is generally incandescent lamp 5 times.

Recently, the national development and Reform Commission said the leadership in the elimination of inefficient lighting products international seminar, the state is currently developing out of inefficient lighting products roadmap, phasing out the incandescent lamp stage plan of different types, the promotion of efficient lighting products.

No more than 10 years

The so-called roadmap is the time to completely eliminate the incandescent lamp, as well as the way to eliminate the overall plan. The industry believes that all the incandescent lamp no longer than 10 years, which means that the replacement of energy-saving fluorescent lamp, incandescent lamp, LED energy-saving halogen lamp, metal halide lamp, incandescent lamp will occupy the future after exiting the market blank. In addition to the timetable, the NDRC is still in the phase out of incandescent lamps to promote energy-saving lamps supporting policies and special planning.

However, some experts believe that the current use of efficient energy-saving lamps gradually replace incandescent, there are still two major difficulties. First, the quality of energy-saving lamps is still uneven, some lighting is not suitable for the use of energy-saving lamps. Followed by the traditional incandescent lamp, energy-saving lamps are still much higher than the price, the current fiscal policy to encourage efficient lighting subsidy policy is too simple. All in all, energy saving lamps and LED lights who can solve the two major problems of cost and environmental protection, who will become the future of the source of light.

The environmental cost of a large number of energy-saving lamps

At present, the application of energy-saving lamps in the country is more popular. The Commission also repeatedly said, will focus on the promotion of the use of low mercury, mercury solid technology and clean production process quality and environmental protection efficient lighting products, at the same time, encourage enterprises to carry out clean production, waste lamp recycling pilot, the establishment of waste lamp recycling mechanism.

It is understood that, from 2008 onwards, China's fiscal subsidies to promote efficient lighting products, the use of energy-saving lamp products for urban and rural residents and large users were given 50% and 30% subsidies. 2008-2009, financial subsidies to promote efficient lighting products 210 million, the annual saving 8 billion 800 million kwh, 8 million 800 thousand tons of carbon dioxide emissions. This year plans to promote efficient lighting products more than 150 million. From the current implementation effect, energy saving effect is very obvious.

However, on the occasion of the launch of energy-saving lamps in full swing, but it broke its invisible environmental problems. According to media reports, an ordinary energy-saving lamp contains an average of 0.5 milligrams of mercury, and 1 mg of mercury into the ground will cause about 360 tons of water pollution, the implementation of the compulsory recycling mechanism has become the most urgent things, otherwise, the change of energy-saving lamps will also pay to measure environmental costs. However, the establishment of mandatory recycling mechanism is not easy, China's existing waste recycling system is the most helpless short board.

LED core technology in foreign companies

Some experts predict that the current most likely to replace incandescent lamp is a large flow of LED lights. The development of LED lamp does not exist on the pressure of environmental protection, raw materials required for the supply of raw materials is also very abundant. However, experts China Lighting Association said that although people are optimistic about the LED market, but domestic enterprises are mainly concentrated in the downstream packaging and application fields of LED, there are several core technology is still in the hands of foreign enterprises: one is the power chip, CREE is one of the most important LED chip manufacturers; the other is the fluorescent powder, we basically have to use Japan's Nichia chemical products.

Fortunately, however, can not be reduced to the downstream assembly workshop has become the consensus of the domestic LED companies. In January this year, three optical ho throw 12 billion yuan to set up a LED base. Sanan optoelectronics currently has an annual output of epitaxial wafers 450 thousand, 15 billion chip production capacity. Wang Lianghai, vice president of the same side Limited by Share Ltd also said that has mastered the core technology of high-power chips, epitaxial wafer production. We will focus on the development of high-end chips in the future, and then supply to the domestic downstream packaging plant. Wang Lianghai said that in the future with the introduction of a series of government support policies, the same side will also launch related civil products, enter the broader market prospects of the home market.

East China Sea incandescent lamp 3 billion 400 million annual output

September 1, 2009, the EU out of the first step to stop the use of incandescent lamps, no longer produce or import more than 100 watt incandescent lamp, the next 3 years will be staged to stop the use of incandescent lamps. In November 2009, China gradually phased out incandescent lamps, accelerate the promotion of energy-saving lamp project bidding, China is determined to energy-saving emission reduction results.

An industry source told reporters: at present, the annual use of the global incandescent lamp is 15 billion, China is the largest producer of incandescent lamp, the annual output of up to 3 billion 400 million, of which about half of exports.
