LED's "helpless" and "pale" heat

Look at this summer to get people hot and look at the floods this summer. It is not energy saving and environmental protection, lest the world is not chaotic!

As a result, after many natural disasters, people deeply pondered that energy conservation and environmental protection were carried out without hesitation. The government strongly supported and many companies responded to the call. People are expecting an energy saving and environmental protection revolution.

LED lighting fixtures are worthy of the new energy-saving king. In just a few years, they have become household names and have caused the market to become fiery. The market is hot, but it is so hot and helpless. With regard to LED lighting, the number of good news once again flooded with the headlines of major websites and impacted people's eardrums. Only people who are now persistent will be unable to afford the spirit of "wolf."

We tried to understand the energy saving principle of LED:

First, the maximum conversion of energy into light energy; Second, the manufacture of the most suitable for human visual sense of light.

When we compare LED lamps with traditional energy-saving lamps, we can make a very clear judgment. LED lamps are energy-efficient. Having said this, everyone will think that energy saving is not enough?

Let's take a look at the major problems that the current LED lighting has influencing the market: heat dissipation problems, life problems, weight problems, efficiency issues, light perception issues, and price issues. The above six problems are actually from the energy saving principle of LED lighting.

First, since there is a heat problem, it shows that LED lighting does not maximize the conversion of light energy to light energy, and even not as good as ordinary fluorescent lamps.

Second, since the heat output of the LED is so high that it can affect the heat dissipation, the temperature can be seen in general. With regard to LED light sources, what kind of material can withstand tens of thousands of hours of hot baking? Of course, such high-quality materials exist, but the price can be prohibitive.

Third, on the issue of life, in fact, very simple, the heat emitted by the LED chip will affect the life of the LED light source itself, leading to light failure; In addition, it will also affect the life of the LED lamp PCB driver board.

Fourth, it is precisely because the heat generated by the LED lamp is large, so it needs heat dissipation. Compared to lightweight plastics, the thermal conductivity of metal is much better, but it is also much heavier;

Fifth, the problem of light perception, in fact, is not a fatal flaw in LED lighting. LED lighting products in the case of less power, the reason why after sending a lot of heat can still look bright, this is because the light emitted by the LED easier to stimulate people's visual senses, but this light is too strong, but use Better shades or baffles still solve this dazzling problem to a large extent;

Sixthly, regarding the price, the top five items are naturally self-evident.

LED lighting does not mean energy saving is the thing. The key is to make consumers feel that they are affordable and reliable.

How sensitive is the word "hot" in the field of LED lighting, a "hot" word, how many companies are exhausted, and how many consumers are confused. In the field of LED lighting, there is almost no LED product brand in the Chinese market. The reason is simple and it cannot solve the "hot" problem.

China's professional LED lighting companies seem to be many, in fact, in addition to rectangular lighting, Zhen Mingli, Qinqin and other names can be dozens of companies, the vast majority of little-known small businesses are playing the ball. In fact, from the perspective of the entire Chinese market, LED lighting product production capacity is not large enough to prop up the consumption of more than one billion people in China. Therefore, LED has become a “fire”. How long can the fire? How to continue the fire in the way? This is a lot of LED lighting companies and the people who will soon be involved in the LED lighting industry must face the problem. From the above six issues of LED lighting products, we can easily see, placed in the LED lighting industry is the most urgent and the biggest problem is "hot" rather than "heat!"

We use foreign machinery and equipment to produce wafers, or import wafers from foreign countries and use foreign machines for packaging, and then use foreign machines to process finished lamps. However, the “hotness” remains unabated. So we sell our relatively high-quality products abroad and allow foreigners to pick and choose. Why does China's high technology always depend on foreign countries? Some enterprises even use "imports from abroad" as the backing of the brand's quality.

In those days, the Japanese exchanged peanut-hulled flooring for Chinese peanuts and then sold the peanut shells to the floor to China. When I came to the ship, I didn’t spend a penny and took away a full ship of peanuts. I even took the money from the pockets of the Chinese people. The Chinese still smiled, just because I got a good floor. This kind of floor may only appear in the homes of upper class people. The Japanese are using the principle of winning with science and technology in the world and are in an invincible position.

In fact, Europe and the United States LED lighting products may not be so advanced, it is not necessarily their LED lighting energy and environmental protection to do it. But people have the technology to start the mountain. If you don't want to develop the source of technology and you want to play advanced, then people will "play" you.

The root of the LED lighting problem is the wafer. It is really sad to think that Chinese LED companies are still distressing about the problem of heat dissipation. The wafer does not fundamentally solve the problem of heat generation, and the package cannot be solved naturally. Therefore, how to consider the heat dissipation of the finished product can only solve the “standard” and solve the “specimen”.
