LED lamps and lanterns supermarket no seat price is expensive "tucking point"

"I'm going to get married recently. I'm setting up a new house. The designer makes a vigorous proposal for the living room and the bedroom with LED lights. It says it's energy saving and good - looking. What is the difference between this LED lamp and the ordinary energy saving lamp? " The little Chiang, who is being decorated, is a little puzzled. But in contrast to little Chiang's doubts, IKEA has recently announced that it will only sell LED lamps in IKEA stores around the world since September 1, 2015.

One side is the consumer's "unintelligible", one side is the merchant's "one size fits all", the LED market in the pace of buyers and sellers seems to have been deviant. Reporter yesterday (23) day after the survey found that for many ordinary citizens, LED lamps or lanterns are still a "new gadget", the daily shopping in the supermarket is very difficult to see its figure, and large sellers in nine out of the sellers have been crying in the shop. In the popularity of related performance, "price clearance" is still a consumer's hesitation.

It is difficult to find LED lamps and lanterns in supermarkets

The reporter asked the industry to find that the LED lamp was "a big one". The so-called LED is the English abbreviation of "light emitting diode". This year, three Japanese scientists won the Nobel prize for physics on the basis of the invention of blue light LED. The three scientists exported high - brightness blue beams through semiconductors in the early 90s of the last century. "Their inventions are revolutionary," the Nobel Committee's statement said, "the incandescent lamp is on twentieth Century and will be lighted by the LED light in twenty-first Century." However, judging from the current reflection of domestic consumers, the judgment of "twenty-first Century" has not been confirmed.

"This is all energy saving, just pick it up." In a supermarket near the peony garden, the shopper refers to the various power bulbs of 5W, 15W, 23W and so on. The packing box clearly shows the word "energy saving", but when you hear about "there is no LED bulb", the guide staff replied: "I didn't hear that the family used all of us."

In the larger Carrefour supermarket in Zhongguancun, reporters struggled to find LED bulbs on layers of shelves, but the number of LED bulbs and numbers was numbered in a total of ten layers of double shelves. And "ordinary energy saving light bulb" has become a well deserved "mainstream" on the shelf. There are five or six kinds of brands to be sold, and there are many more shelves.

Metal strip instead of lamp tube

The reporter visited several supermarkets and found that the LED bulbs were either hard to find, or only one corner. But in the Shili River lighting market, LED lamps and lanterns have become the main hit in the shop. When the reporter said, "want to give the bedroom and the living room three lights", the more than 10 shopkeepers made a similar introduction, "the effect of energy saving on the wall is the first level."

When the reporter further inquired, "is this an ordinary energy-saving lamp or a LED lamp", a shopkeeper said directly, "my home is now only selling LED, now it's all the ladder electricity price, and the ordinary energy saving lamp is too bad." Another shopkeepers said, "the ordinary energy saving lamp is the few, and LED whether it is the ceiling or the chandelier, there are dozens of things in my house, and there is always one you like."

The reporter did not know much about the difference between the LED lamp and the ordinary energy saving lamp. A shopkeeper directly brought a LED dome light to dismantle the lampshade. "A lot of people are like you. I don't know how the LED is going. I specially dismantled a lecture for the customers." In this "naked light", the reporter saw that it is not the usual lamp inside the ordinary lamps and lanterns, but the metal strips of various shapes, which are studded with a small rectangular bar that is smaller than the nail cover.

Many LED lamps and lanterns sales owners also admit that most of the customers who have come to buy are the young people seeking fashion, especially the "replacement" of the ordinary energy saving lamps in the home. Why is the consumer's desire to buy limited? "The price is too expensive" has become a "tucking point" - a reporter found that the 3W LED light bulb range from thirty to sixty or seventy yuan, and the ordinary small power saving light bulbs are still less than ten yuan, more than 10 square meters of the living room, the bedroom LED ceiling light "basic" more than three five hundred yuan, and 30W of ordinary energy saving The lights are around one hundred or two hundred yuan.

A year to save the price difference of electric charge

Under the conditions of high price, whether to buy LED lights "good" in the end?

"The biggest difference between the incandescent lamp and the ordinary energy saving lamp and the LED lamp is the principle of luminescence. Incandescent lamps produce thermal luminescence by tungsten wire, only 5% of the electric energy is used for lighting, the rest of the 95% is consumed by heat, and the ordinary energy saving lamp can convert 80% of the electric energy into light energy. The LED lamp, through the light emitting diode, can directly convert the electricity into light, and the power consumption is lower. In theory, the energy consumption of LED is only 1/10 of the incandescent lamp, which is 1/4 to 1/3 of the ordinary energy saving lamp. Liu Lei, the manager of the technology support department of Beijing South Rui Zhi core microelectronics technology company, told the reporter.

Take 3W's LED lamp as an example (according to the market price of 30 yuan), compared with the equivalent brightness of the 12W ordinary energy saving lamp (about 15 yuan), if the light is 8 hours a day, the use of LED lamp will save 0.072 degrees of electricity, save 26.28 degrees a year, according to the unit electricity price of 0.48 yuan / degree, can save about 12.6 yuan of electricity, more than one year will be possible. "Make up" the initial purchase price difference. At the same time, LED lights are longer than ordinary energy saving lights - the most popular PHILPS ordinary energy saving lamp is "life span of 3 years". The LED lamp's qualified product life is generally over 10 years or even 20 years. In this way, the LED lamp can be used continuously in 10 years, and the ordinary energy saving lamp may have been changed about three times. With the advantages of long life and low energy consumption, the LED lamp is more cost-effective than the ordinary energy saving lamp for the long - used family.
