How does LED lighting cross the 'price close'1

I am going to get married, and I am arranging a new house. The designer has proposed to install LED lights in the living room and bedroom, saying that it is energy-saving and beautiful. What is the difference between this LED lamp and ordinary energy-saving lamp? 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 from September 1, 2015. On the one hand, the consumers are unintelligible, and on the other hand, the merchants are across the board. The pace of buyers and sellers in the LED market seems to be biased. After visiting and investigating yesterday, it was found that for many ordinary citizens, LED lamps are still a new gadget, and it is difficult to see it in supermarkets that they visit everyday. nine out of ten sellers in large stores have already sold in the store. After being popularized, the price is still a hurdle for consumers to hesitate. It is difficult to find LED lamps in supermarkets. After asking people in the industry, they found that LED lamps have a great background. The so-called LED is the English abbreviation of LED. This year, three Japanese scientists won the Nobel Prize in Physics for the invention of Blu-ray LED. The three scientists exported high-brightness blue beams through semiconductors in the early 1990s s. Their invention is revolutionary. The Statement of the Nobel Prize selection committee said that incandescent lamps lit up the 20th century and the 21st century will be lit up by LED lamps. However, from the current reflection of domestic consumers, the judgment of lighting the 21st century has not been confirmed. This rack is energy-saving, just pick it. In a supermarket near the Peony Garden, the shopping guide pointed out that 5 W, 15 W, 23W and other bulbs of various powers are available, and the words of energy saving are clearly visible on the packaging box. however, when I heard about the question of whether there were LED bulbs, the shopping guide replied: I have never heard of them. Generally, we use them at home. In the larger Carrefour supermarket located in Zhongguancun, I struggled to find the LED bulbs on the layers of shelves, but in the double-row shelves with a total of ten floors, there are only a handful of LED bulb brands and quantities. The ordinary energy-saving light bulbs have become the mainstream of the shelves. There are five or six brands for sale, and there are many more shelves. The metal strip replaced the lamp and visited several supermarkets. It was found that the LED bulb was either difficult to trace or only occupied a corner. However, in the lighting market located in Shilihe, LED lamps have become the mainstay of the store. When the author said that he wanted to install three lights for the bedroom and living room, more than a dozen shopkeepers made similar recommendations. The energy-saving effects on the wall are all first-class. When further asking whether this is an ordinary energy-saving lamp or an LED lamp, a shopkeeper said directly: my family only sells LED now, and now the electricity price is stepped. Ordinary energy-saving lamps are too deficient. Another shopkeeper said: there are only a few kinds of ordinary energy-saving lamps, and whether LED is ceiling or chandelier, there are dozens of them in my family, and there is always one you like. Seeing that I don't know much about the difference between LED lamps and ordinary energy-saving lamps, a shopkeeper directly brought an LED ceiling lamp that removed the lampshade. Many people are the same as you. I don't know what LED is. I specially opened one to tell the customer. On this bare lamp, it can be seen that the inside is not the normally visible lamp tube inside the ordinary lamp, but the metal strips of various shapes, which are dotted with rectangular strips smaller than the fingernail.
