Incandescent lamps will be banned from sale next month, and it is difficult to see them on the market. On November 14, 2011, the National Development and Reform Commission and other five ministries and commissions issued a roadmap for the phasing out of incandescent lamps in China. According to the road map, the final time for the implementation of the elimination of incandescent lamps in China will be until September 30, 2016. Since October 1, 2016, China may ban the import and sale of ordinary lighting incandescent lamps of 15 watts or more. Recently, the author visited Luqiao China Building Decoration Lighting City. Most merchants said that in fact, since the ban on whitening in 2011, incandescent lamps have gradually withdrawn from the market. The current stock is very small, and it is even hard to find incandescent in the lighting market. light. Incandescent lamps of 15 watts or more or the market will have little impact on the luminaires. The incandescent lamps were invented by Edison and have been used for 137 years. In 2011, China released the roadmap for the elimination of incandescent lamps in China. According to this roadmap, China will set the transition period from October 1, 2011 to September 30, 2012; from October 1, 2012, China will ban the sale and import of incandescent lamps for general lighting of 100 watts or more; From October 1, 2014, it is forbidden to sell and import incandescent lamps for general lighting of 60 watts and above, and it is prohibited to produce, sell and import inefficient tungsten halogen lamps with luminous efficacy below the energy efficiency limit according to energy efficiency standards; 2015 From October 1st to September 30th, 2016, China will evaluate the previous policies and adjust the follow-up policies. If the assessment is successful, China will ban the sale and import of incandescent lamps for general lighting of 15 watts and above from October 1 this year. The author recently visited the China Building Decoration and Lighting City in Luqiao, and found that many shops are marked with LED lighting shops. Yan Yunde, who is a lighting company, told the author that although incandescent lamps have not been completely banned, LED lights have already become the absolute protagonists in the market. Since 2011, incandescent lamps have begun to withdraw from the market. Although the price of incandescent lamps is much cheaper than that of energy-saving lamps, more people will choose energy-saving lamps. Yan Yunde said. In addition, the salesperson of the Opto Lighting Taizhou Operations Center told the author that as early as three or four years ago, the store did not sell incandescent lamps, and currently the stores are almost all LED lights. Basically, customers are asking to buy LED bulbs. The LEDs and energy-saving lamps are also sold in the store. The ordinary lighting incandescent lamps are eliminated. There is also a stock that cannot be sold out in the store, so the impact on us is relatively small. . The salesperson said. Consumers have become accustomed to LED lights with long life and low power consumption From the roadmap of China's elimination of incandescent lamps released in China in 2011, the target product range of elimination has also extended from high power to low power. Compared with incandescent lamps, lighting manufacturers are more willing to recommend energy-saving lamps, LED lights, etc. to consumers. Yan Yunde told the author that although incandescent lamps are low in price, they have high energy consumption and low luminous efficiency. LED lamps have a long life span of about 20,000 hours. They can last for several years in commercial office use and more than ten years in home use. And a 3 watt LED lamp consumes about the same amount of a 10 watt incandescent lamp. In addition, the brightness of the same wattage LED lamp is 2-3 times higher than that of the incandescent lamp, so it saves the daily electricity consumption and saves energy for the merchants who need to display a large number in the store. Consumption. Yun Yunde said. Incandescent lamps are constantly being phased out. In fact, the replacement speed of LED lights is not slow. Yan Yunde said, don't look at the LED lights in the market are the same, in fact, LED lights are like electronic products, every 3-4 months of new products have significant progress. The author understands that the heart of an LED is a semiconductor wafer. When a current is applied to the wafer through a wire, electrons and holes are pushed into the vector sub-trap. In the quantum well, electrons are combined with holes, and then photons are used. The form emits energy, which is the principle of LED illumination. When I saw Ms. Yang, she was purchasing lamps at the Opto Lighting Taizhou Operations Center. In the face of a dazzling array of lamps, Ms. Yang did not hesitate to tell the salesperson that she would buy LED lights or energy-saving lamps. LED lights are low in power consumption, long in life, fast in response, and low in pollution, and the lamp ornaments made by them are very beautiful, so LED lights are my first choice. Ms. Yang said.
