The past and present of incandescent lamps More than 130 years ago, the great inventor Edison finally discovered the carbonized cotton thread after testing more than 1,600 kinds of heat-resistant materials. Therefore, he put the carbonized cotton thread into the glass ball and then vacuumed the ball. As a result, the carbonized cotton filament emitted bright and stable light for more than 10 hours. In this way, the incandescent lamp representing the bright carbonized cotton silk was born, and humans have since bid farewell to the night and walked into the light.
After more than one hundred years, technology has continued to improve. Incandescent lamp is the least efficient type of lighting in all lighting tools. Because it consumes only 12-18 energy, it can be converted into light energy. The other part is lost in the form of heat energy. It has been reduced by many countries to reduce greenhouse gas emissions. Agenda. Australia, Canada, Japan, and the European Union have successively banned the production and sale of incandescent lamps in recent years.
On November 1, last year, the National Development and Reform Commission, the Ministry of Commerce, the General Administration of Customs, the State Administration for Industry and Commerce, and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued the "Announcement on the gradual ban on the import and sale of ordinary lighting incandescent lamps", decided from October 1 this year. From the beginning of the day, the import and sale of ordinary lighting incandescent lamps are banned step by step according to the power level.
The "Announcement" clarifies that the target product to be phased out is an incandescent lamp for general lighting, and does not include other types of incandescent lamps such as reflective incandescent lamps, spotlights, decorative lamps, and special-purpose incandescent lamps. It is divided into five phases: the transition period from November 1, 2011 to September 30, 2012. It is forbidden to import and sell ordinary lighting incandescent lamps of 100 watts or more from October 1, 2012. By 2016, ordinary Illuminated incandescent lamps completely withdraw from the historical stage.
Saying goodbye to incandescent lamps, the market is still reluctant. Today, it is less than 20 days from the first stage to ban the import and sale of ordinary lighting incandescent lamps of 100 watts or more. Say goodbye to traditional incandescent lamps, is the market ready?
Recently, the reporter visited some supermarkets and lighting markets in the city and found that ordinary lighting incandescent lamps are still on sale, but the number is small.
In a lighting shop near Shangdu, when the reporter asked if there was an incandescent lamp for sale, the boss immediately took the lead to pick up the lights. The reporter asked: Is there 100 watts? Yes, how much you want. When asked about the policy that the general incandescent lamp of 100 watts and above will be banned from October 1 this year, the boss said: This is not clear, but now the people still need it, and the policy does not work. The boss later said that although there are still people buying traditional incandescent lamps, there are more customers who buy energy-saving lamps.
In the Yiwu Small Commodity Direct Supermarket in Tianjiu Street, all kinds of light bulbs are coming over. A closer look reveals that the dazzling array of light bulbs is basically based on energy-saving lamps, and there are eight or nine boxes of traditional incandescent lamps on the left side of the bottom two shelves. The reporter roughly calculated that the price of incandescent lamps with a power of 25 watts and 40 watts is 1.5 yuan, and the others have 100 watts, while the largest incandescent lamp has a power of 200 watts for only 2.5 yuan. In contrast, the power of various energy-saving lamps that occupy the shelf is mainly concentrated at 9-40 watts, the price is between 8-22 yuan, and the maximum power energy-saving lamp has 120 watts, and the price is 40 yuan.
Although the price of energy-saving lamps is generally several times that of incandescent lamps, but the owner of the small commodity supermarket told reporters that household lamps are still generally selected energy-saving lamps, and customers value energy-saving features. However, the proprietress also said that it is not clear about the ban on the sale of incandescent lamps of 100 watts or more next month.
Similarly, in the Huarun Wanjia Libo store, it is easy to see the figure of incandescent lamps. The difference is that the traditional incandescent lamps sold in supermarkets are mainly 25 watts and 40 watts, and there are no incandescent lamps with power of 100 watts or more.
The supermarket manager told reporters that although it is not very clear that the ban on the sale of ordinary lighting incandescent lamps of 100 watts and above will be carried out next month, they have not sold such lamps for some time. If the goods stipulated by the state cannot be sold, they will not be sold in the counter, and the other big stores will be the same.
Energy-saving lamps, is your home safe?
Speaking of incandescent lamps, the reporter found that after 80s and 90s, the impression may not be deep. As far as the reporters themselves are concerned, the memories of incandescent lamps have to return to years ago.
Miss Luo is a typical 80-year-old. She has been working for more than two years. When the reporter asked if there was a traditional incandescent lamp at home, she first asked what was an incandescent lamp. After the reporter’s description had a general impression, Miss Luo said : This lamp has rarely been seen since the renovation of the second home. Now Miss Luo's family, most of them are fluorescent lamps and energy-saving lamps: As the name suggests, energy-saving lamps are more energy-efficient.
In the era of increasing environmental awareness and energy-saving publicity, energy-saving lamps have become the first choice for many newly renovated homes.
Miss Ye is getting married next month and the new home is under renovation. When choosing the lamp, she first considered the aesthetic problem, followed by energy saving. Combined with the budget, she finally chose a decorative lamp composed of many small energy-saving lamps, while the kitchen chose the most common energy-saving lamps. In her view, the decoration of the average family is both good-looking and durable. Incandescent lamps are more expensive and outdated.
According to network data, in 2010 China's incandescent lamp production and domestic sales were 3.85 billion and 1.07 billion respectively, and the output in 2011 was 4.17 billion. It is estimated that China's lighting electricity consumption accounts for about 12 of the total electricity consumption of the whole society. If you replace all the incandescent lamps in use with energy-saving lamps, you can save 48 billion kWh a year, which is equivalent to reducing carbon dioxide emissions by 48 million tons.
The promotion of energy-saving lamps is also an energy-saving measure that the country has long promoted. Since 2008, the state has implemented a financial subsidy policy for high-efficiency lighting products to guide enterprises to produce energy-saving lamps and encourage consumers to purchase. Since the implementation of this policy for many years, it has been seen from the consumer's purchase response that good results have been achieved.
Similarly, the reporter learned from the Municipal Economic and Information Bureau that the city has made relevant preparations for the country’s ban on sales from next month. The energy department of the bureau, Mr. Pan, revealed that from 2008 to 2011, the city has promoted nearly 700,000 high-efficiency energy-saving lamps for the state's financial subsidies, achieving an annual energy saving of about 138 million kWh. Next, the city will take a series of measures to phase out incandescent lamps. On the one hand, it will increase the promotion of high-efficiency energy-saving lamps, especially the promotion of high-efficiency energy-saving lamps with financial subsidies from the state to gradually replace incandescent lamps; on the other hand, it will strengthen the inspection of the incandescent lamp sales market and at the same time play the role of the energy monitoring brigade. Carry out special inspections on the use of incandescent lamps in industrial enterprises, trade and tourism industries, and ensure that incandescent lamps are eliminated on schedule.
