LED lights are difficult to win because of the low style and high price.
LED lights are known for their energy saving and environmental protection. Because of the promising market prospects, large-scale LED projects have been launched all over the country. However, in the market, the reporters learned that the LED lights that people can see are actually not many, but consumers are not satisfied with the products already on the market, and the buyers are embarrassed.
High price awareness
LED lights have been sold in some supermarkets and lighting markets, but most consumers don't know about such lights. Not only that, but even if sellers introduce the superior performance of such lamps to consumers, most people still shake their heads. Not willing to buy.
The reporter interviewed 15 consumers randomly before the LED lamp sales counter in Beijing Metro, asking them if they knew about LED lights. Only two of them can tell the merits of the product. Of the remaining 13 consumers, 3 have heard of the light, but said they don’t understand.
Consumers are less aware of LED lights, but even consumers who understand the advantages of the product say they will not buy because the price is too high.
A consumer who said that he knew about LED lights said to reporters: "I saw this product from the Internet to save energy and protect the environment. Just when the house was going to be renovated, I decided to buy this kind of lamp. But in the lighting city and supermarket, I ran a circle, I I decided to give up. The price of this kind of lamp is too confusing, some are more than 1,000 yuan, some are only one hundred yuan. The price is so chaotic, this market is also chaotic, I will not pick, so no Dare to buy."
Another consumer said: "I have seen that there are only a few models in the market that include some brand-name stores. The choice is small and the price is high. I will not buy it anyway."
The reporter learned from a lighting distributor that the current price of LED lights is indeed relatively high, generally about 10 times that of ordinary lamps, which makes it difficult for many consumers to accept. The cheapest LED lamp on the market, the nominal power of 0.9 watts (brightness equivalent to 25 watt incandescent lamps), the price is also 30 yuan, 6 times the price of the same brightness incandescent lamp, twice the price of ordinary energy-saving lamps . The price of LED desk lamps is often as high as 8,000 yuan, and the price of imported brands is thousands of dollars, which is 10 times the price of ordinary lamps.
The quality of the products is mixed.
The price confusion has made consumers feel that the market for LED lights is also a bit messy. The consumer feels nothing wrong.
According to the reporter, after a large supermarket used LED lamps for more than a year, the replacement rate reached 80%, causing the supermarket management to refuse to use LED lights. The reason is that the original manufacturer has no products at all, the products are OEM, there is no means of testing, there is no way to detect the quality of the products, let alone the quality of control. Coincidentally, a subway company in the north tested the LED lamps of several companies and found that there were also problems such as severe light decay and heat dissipation.
Insiders pointed out that the LED lamp market is mixed, and the price of poor quality products is similar to that of ordinary energy-saving lamps, but the service life is greatly reduced. Among the enterprises engaged in LED high-power lighting, there are only a few independent intellectual property rights, many of which are produced by OEM and OEM, resulting in uneven product quality.
According to reports, the most difficult technical problem for LED lamps at present is heat dissipation. The difference between good product quality and long service life depends on this. Poor quality LED lamps, the driver board may have a life of only 5 years at 70 ° C, far from the 10 years of LED wick use. So compared to fluorescent lamps of the same brightness, the latter is much more cost effective. In addition, when the LED light is damaged, the wick is not broken, but the entire lamp is replaced. To be sure, consumers will not like such products.
Technical aspects still need to be improved
Since its inception, LED lights have been known for their environmental protection, energy saving and longevity. Some materials have publicized their life expectancy of 50,000 hours or even 100,000 hours, but the actual use is not the case, which also seriously dampen the enthusiasm of consumers.
In the interview, a consumer said that she bought a LED desk lamp from the Internet and it took more than a year to break down, but the product manual said that it can be used for 5 years.
Yu Anqi, senior auditor of the National Lighting Quality Supervision and Inspection Center, said that in landscape lighting and backlighting, LED lights can basically achieve longevity, but in the field of general lighting, LED lights can't do this.
LED lights are most afraid of high temperatures. Once the heat is not good, the luminous efficiency is low and the service life is short. Yu Anqi revealed that they conducted experiments on more than 70 batches of LED lights for road lighting and tunnel lighting. After 1500 hours of lighting, about 70% of the product's lumen maintenance rate (an indicator of life) is 80. %the following. "The product is expensive, only the service life is longer, the maintenance factor is better, otherwise it does not mean." Yu Anqi said.
Yu Anqi also pointed out that poor color rendering is also one of the obstacles for LED lights to enter the field of indoor lighting. When you use a light that has poor color rendering, the color you see will be distorted. According to the standard, the color rendering of indoor lighting should reach 80, incandescent lamps and fluorescent lamps can be achieved, but LED lamps are still not available. Or the color rendering is achieved, the light effect is not enough, and the two cannot be balanced. This is the direction that enterprises need to work hard.
At present, there are not many models of LED lights, and consumers are not accepting such lamps. In fact, it is not the designer who does not care. The key is that it is difficult to overcome. For example, in a spiral-type luminaire, the weight of a fluorescent lamp is much lighter than that of an LED lamp. At the same time, because there is no problem with the heat sink, the weight of the fluorescent lamp can be neglected for the lamp holder, but the weight of the LED lamp is definitely a test for the lamp holder.
Although LED lights are still facing many problems, experts believe that through continuous innovation of technology, LED lighting will become more and more mature in the future, and the stability of LED lights will be further improved. The future will be an era of efficient lighting.
