The most tempting and most vocal words in the LED industry

Today is 5.20, and there are always people who are happy about the confession. The failure of confession is not terrible. The terrible thing is the reason for those who hang people. The most refusal of the most praised person in history is that you are a good person, but we are not suitable. Are you suitable for the bad guys...

In fact, not only when the confession is rejected, there will be such a pitfall, and we will go through a lot of things.

When I was a child, the teacher said the most boring words: "I don't ask you to recite this text, but you will dictate." God! Tell me how to write without me?

Stocks have been stocked. The most "pit people" in the stock market is: "The extent of the decline will not be too deep." This was the case ten years ago, and it is still the case. The result fell below 2,300 points from 6000 points.

When I was at work, the leader said before coming to the stage: I will simply say a few words below. The result is over an hour...

I suddenly thought of a sentence here: I don’t want to lie to me when I read less!

So is there such a hole in the LED industry? Of course, there are also. LED companies always have a good time in propaganda, but consumers are another look, always letting our tears fall to the end...

First, the life of LED products can reach 100,000 hours

All along, the state and enterprises in the promotion of LED lighting, with a long service life as a major rhetoric, the promotion of LED lights life of up to 60,000 to 100,000 hours, is more than 10 times the ordinary lighting bulbs, so energy-saving and economical . However, after several years of promotion, people used LED lights and found that their lifespan was far less than publicity.

The same is true for LED displays. Although the theoretical life of LED is 100,000 hours, it can work for more than 11 years according to 24 hours a day, 365 days a year, but the actual situation and theoretical data are much worse. According to statistics, the life expectancy of LED displays on the market is generally 6~8. In the year, the large LED screen that can be used for more than 10 years is very good, especially the outdoor LED display, the life is even shorter.

Experts pointed out that although the theoretical life of LEDs is as high as 30,000 to 50,000 hours, it is not so ideal after being made into lamps or display products. At present, domestic LED technology is not mature. The quality of LED products on the market is uneven. Many products are just playing. Energy-efficient signs, its service life, such as some inferior LED lighting products are not even as good as ordinary energy-saving light bulbs, even for qualified products, its light output will be reduced with time, and the life expectancy will be several thousand hours.

Second, the political tender: welcome strong companies to participate in the bidding

Since the development of the LED industry, engineering channels are still the main channel for the LED display products to advance the market. Compared with retail and wholesale dealer channels, the large amount of engineering channels and high profits are conducive to the brand promotion of enterprises and have a high influence on enterprises. However, according to relevant industry sources: "Outdoor projects belong to municipal projects, and they all use the government's relationship. It is impossible to let only one family do it. Other homes can't do it. There are many 'hidden rules' in it."

It is understood that in China, a project involves many units or levels, including owners, architects, construction parties, lighting and interior designers. Who has the absolute right of making a decision when purchasing a building material product? No one can give a definitive answer. It can be said that these rights and responsibilities are still unclear.

In fact, the engineering channel has relatively high requirements on the strength of the enterprise, including the requirements for the enterprise itself, such as the “project case of major projects, the test report issued by the national testing organization, and the qualification of product certification”. However, some surveys show that 60% of Guangdong entrepreneurs are engaged in relationships, 10% are used for life, and only 30% of their work is done. It can be seen that if enterprises develop well in the industry, they must first have a “good relationship”. A strong relationship can often make the development of the enterprise “improving the icing on the cake”. . An industry insider who asked not to be named said that if you get government subsidies or projects, both hard power and soft power must be available, but soft power is more important than the two. "This is a critical time to test connections and government resources."

In this regard, some industry analysts said that evading bidding, false bidding, and bidding, from the perspective of LED bidding, whether it is government procurement or engineering construction projects, often just entering the bidding process, under the collusion between government and business, through Deliberately manipulating bids creates a chain of corruption involving a wide and rigorous system, and many institutional regulations are therefore ineffective. At the same time, the corruption involved in LED bidding tends to be concealed, and the existing laws and regulations are lagging behind, which leads to difficulties in supervision and investigation, and it is urgent to attract the attention of relevant departments.

Third, LED product procurement: the brighter the LED light, the better

The brightness of an LED product depends on the quality of the LED chip and the magnitude of the drive current. If a low-quality LED has a higher drive current, it will be brighter than a high-quality LED at the beginning of the work. However, too high a current will cause the LED to heat up too quickly, and the end result is that the brightness becomes dark or burned. In order to facilitate sales, some manufacturers use inferior chips and use the method of increasing the driving current to increase the brightness of the LED lamps to mislead the purchaser, but this will lead to a significant reduction in the service life of the LED lamps. Therefore, in the choice of LED lights, it is not the brighter the better, but a matching drive current is needed to make the lamp produce normal brightness to ensure the service life of the LED lamp.

Fourth, LED display is energy-saving products, can save electricity costs

It is true that LED energy can be saved without energy. If the products made with LEDs are definitely energy-saving, it is another matter. In the past few years, the advertising industry has developed rapidly! The LED large screen has also rapidly exploded! But the LED large screen power consumption is a problem! Power is big! A screen of more than 100 square meters will cost one hundred and twenty thousand a year!

For example, the conventional P16 outdoor LED display has an average power of 272 W/m2. Assuming 14 hours a day, China has installed 12 million m2, and the annual power consumption of the Chinese outdoor LED display is 16.7 billion kWh, equivalent to about 60 days of power generation in the Three Gorges Dam, equivalent to about 8.5 million tons. Raw coal consumption, nearly 17 million tons of carbon dioxide emissions.

In summary, for outdoor LED display products, the power consumption is relatively large, so it can not be said that the outdoor LED display can really save energy. At present, LED display manufacturers are also working hard to develop energy-saving LED displays, and we are also looking forward to more excellent energy-saving LED display products.
