Recently, I am getting married, and I am setting up a new house. The designer has proposed a living room and a bedroom with LED lights, which is energy-saving and beautiful. What is the difference between this LED light and ordinary energy-saving lamps? Xiao Jiang, who is being renovated, is a bit confused. However, in contrast to Xiao Jiang’s doubts, IKEA recently announced that it will only sell LED lamps in IKEA stores worldwide starting from September 1, 2015. One side is the consumer's unintelligible, and the other is the one-size-fits-all business. The pace of the buyers and sellers in the LED market seems to be biased. After interviewing the survey yesterday, the reporter found that for many ordinary citizens, LED lamps are still a new thing. It is difficult to see it in the supermarkets that are visited every day, and in the large stores, there are ninety-nine sellers in the stores. Drink and sell. After being popularized, the price barrier is still a hurdle for consumers to hesitate. It is difficult for supermarkets to find LED lamps. After consulting the industry, LED lights can be said to be very popular. The so-called LEDs are the English abbreviation for LEDs. This year, three Japanese scientists won the Nobel Prize in Physics for their invention of blue LEDs. The three scientists exported high-brightness blue beams through semiconductors in the early 1990s. Their invention was revolutionary, and the Nobel Prize-winning committee’s statement said that incandescent lamps lit up in the 20th century, and the 21st century will be illuminated by LED lights. However, judging from the current domestic consumer response, the judgment of lighting up the 21st century has not been confirmed. This rack is energy efficient, just pick it. In a supermarket near the Peony Garden, the shopping guides pointed out that 5W, 15W, 23W and other power bulbs were all available, and the words “energy-saving†were clearly visible on the box, but when there was an inquiry about LED bulbs, The shopping guide answered: I have never heard of it. Generally, we use these kinds of homes. In the larger Carrefour supermarket in Zhongguancun, Beijing, reporters struggled to find LED bulbs on stacked shelves, but in a total of ten-story double-row racks, there are only a handful of LED bulb brands and numbers. The ordinary energy-saving light bulbs have become the well-deserved mainstream on the shelves. There are five or six brands for sale, and there are many more shelves. Metal bars replaced lamps and visited a number of supermarkets, and found that LED bulbs are either difficult to trace or only occupy a corner. However, in the lighting market located in Shilihe, LED lamps have become the mainstay of the store. When the reporter said that he wanted to give three lights to the bedroom and the living room, more than a dozen shopkeepers made similar promotion effects on the wall. When further inquiring about whether this is an ordinary energy-saving lamp or an LED lamp, a shop owner directly said: My family now only sells LEDs. Now, the price of electricity is stepped up, and the ordinary energy-saving lamps are too bad. Another shop owner said: ordinary energy-saving lamps are just a few, and LEDs are either ceiling or chandeliers, there are dozens of models in my family, there is always one you like. Seeing that I don’t know much about the difference between LED lights and ordinary energy-saving lamps, a shopkeeper directly brought in an LED ceiling lamp with a lamp cover removed. Many people are just like you. I don’t know what LED is going on. I specially removed one. Tell the customer. On this bare lamp, the reporter saw that it is not a lamp that is commonly seen inside ordinary lamps, but a metal strip of various shapes, which is inlaid with a rectangular strip smaller than the fingernail. Many LED lighting sales shop owners also admitted that most of the customers who came to buy are young people who are pursuing fashion, especially the replacement of ordinary energy-saving lamps in their homes. Why are consumers' desire to buy limited? The price is too expensive to become a Tucao spot reporter found that 3W LED bulbs range in price from 30 yuan to sixty-seven yuan, while ordinary low-power energy-saving bulbs are less than ten yuan, for more than ten square meters of living room The basic ceiling of the LED ceiling lamp in the bedroom is three to five hundred yuan, and the ordinary energy-saving ceiling lamp of about 30W is about one or two hundred yuan. One year saves the electricity bill to make up the difference in the price of the lamps. Under the condition of high selling price, is it possible to buy LED lights? The biggest difference between incandescent lamps and ordinary energy-saving lamps and LED lamps is in the principle of illumination. Incandescent lamps generate heat through tungsten filaments. When used, only 5 of the electrical energy is used for illumination. The remaining 95 are all consumed by heat. Ordinary energy-saving lamps can convert 80 electrical energy into light energy. The LED light can directly convert electricity into light through the light-emitting diode, and the power consumption is lower. In theory, LEDs consume only one-tenth of the energy of incandescent lamps, and are one-quarter to one-third of ordinary energy-saving lamps. Liu Lei, manager of Beijing Nanrui Zhixin Microelectronics Technology Co., Ltd., told reporters. Take 3W LED lamp as an example (calculated according to the market price of 30 yuan), and compare the brightness of 12W ordinary energy-saving lamps (about 15 yuan). If you light up for 8 hours every day, using LED lights will save 0.072 kWh, saving one year. 26.28 degrees, according to the unit price of 0.48 yuan / kWh, can save electricity costs of about 12.6 yuan, more than a year can be used to fill the initial purchase price difference. At the same time, LED lights are longer than ordinary energy-saving lamps. The most popular Philips ordinary energy-saving lamps are marked with a life span of up to 3 years. LED lamp qualified products generally have a life span of more than 10 years or even 20 years. Based on this calculation, LED lights can be continuously used for 10 years, and ordinary energy-saving lamps may have been replaced three times. It combines the advantages of long life and low energy consumption. For long-term use, LED lights are more cost-effective than ordinary energy-saving lamps.
