"Incandescent lamps illuminate the 20th century, and LED lamps will illuminate the 21st century. ”
This is the Nobel Prize in Physics for LED lights.
As early as the 60s of the 20th century, LED light-emitting diodes were "born" in the hands of scientific researchers.
Slowly, with the continuous evolution of technology, LED lights have entered the lives of the public as a lighting tool.
The emergence of LEDs once gave the lighting industry more possibilities and gave people more choices.
However, now more and more people seem to have a bad impression of LED lights and are reluctant to buy them.
So why is this happening now?
Cutting corners and short lifespan
The emergence of LED lights not only allows us to see the power of technology, but also gives us consumers more choices.
In the past, even the simplest LED light had 50,000 hours of illumination.
Such a long-lifed lamp has been welcomed by the public.
As a result, more and more industries have abandoned the traditional lighting method and adopted this cost-effective lamp.
In this regard, I believe many people may be confused:
"It can light 50,000 hours? My house can last a year. ”
As for the illumination time of the LED lamp, it is indeed accurate data obtained after trial and error.
So why is the service life of LED lights in the home always very short?
And a large part of this is due to the production process of the factory.
In the process of LED lights entering our lives, there are still many "non-public" procedures and prices.
Don't look at the LED light, there is only a small one, but the processing process inside it is not simple at all
Even many times, LED lights require a dust-free space when they are made.
However, many manufacturers are dust-free, and even ordinary processing procedures have many loopholes.
Now the price of LED lights on the market is generally not high, which leads to little profit in it.
In order to be able to get more profits, many businesses have started to have "crooked thoughts" that they shouldn't have.
Not only did they cut corners, but the LED lights were missing a lot of necessary parts.
As a result, many LED lights on the market can only be purchased again once damaged, and there is no possibility of repair.
Even in order to be able to "drive" the frequency of consumer purchases, the service life of the product is controlled.
As consumers, we enjoy the benefits brought by technology, and at the same time, we want to pursue the due cost performance.
The service life of LED lights is important, but the price of the product is also a major concern.
As a necessity in life, we must have higher requirements for LED lights.
Once LED lights don't meet the standards we have in mind, consumers will naturally choose better lighting tools.
In addition, the decline of the LED light market has a lot to do with its lighting.
Unstable lighting hurts the eyes
Does the light of LED lights affect the health of our eyes?
In fact, whether LED lights can harm our eyes has a lot to do with the "blue light" content inside it.
"Blue light" is actually a kind of optical fiber with a wavelength of about 400~500nm, which is the strongest light in our visible light.
For a long time in the past, although there have been LED lights.
However, the related technology is far from reaching the safe range, which also makes it difficult to ensure the light quality of LED lights.
If the color temperature of the LED light is too low, the environment in the irradiation range will be dull and will not be as effective as it should be.
On the contrary, if the color temperature is too high, it will have a bad effect on our eyes.
As a result, producers can only continue to increase product research and development to improve related deficiencies.
And the question of whether LED lights will harm our eyes has also been answered with the improvement of technology.
On the market, there are clear and rigid requirements for all LED lamps.
If the blue light content is exceeded, the product is not allowed to be sold in the market.
Therefore, there is no need for us to panic at this point, after all, what can reach our hands has been tested.
In fact, in addition to the LED lights we use, electronic products such as TVs and mobile phones also emit blue light.
At present, it is not technically possible to completely eliminate Blu-ray.
Therefore, we can only start from ourselves and reduce the use of electronic products, so as to reduce the harm caused by blue light.
In addition, we have always had some misunderstandings about LED lights.
Saving energy does not equal saving electricity
In the era when there was no electricity, people often relied on kerosene lamps and candles for lighting at night.
With electricity, our lighting tools became incandescent lamps.
Although this tool is very convenient, there is also a big drawback, that is, it is very easy to be damaged during use.
With the continuous evolution of technology, LED lights are slowly emerging.
But now we find that seemingly energy-saving LED lights not only fail to save electricity bills, but also increase electricity bills.
Why is that?
LED lights are energy-efficient because they consume less electricity than other lighting tools.
But nowadays, at night we try to make our house as bright as it is during the day
And this is either to increase the number of lighting tools, or to increase its power.
But either way, it will cause an increase in our electricity consumption.
Compared with the original few watts and tens of watts on the market, the current lamps and lanterns can be said to have changed greatly.
It's not that the current LED lights are not energy-saving, but when our lifestyles change, they also affect the LED lights.
Therefore, in contrast, there will be a conclusion that LED lights do not reduce our electricity bills.
Of course, the changes in the LED light market are also related to our own Xi.
Traditional lighting Xi
White light and warm light are the two most commonly used lighting colors in our lives today.
For a long time, people have been Xi to the colors brought by warm light.
The warm light emitted by the early incandescent lamps always gave people a warm feeling visually.
Just like at sunset, when the sun sets over the earth, we are also released physically and mentally.
For activities when you're relaxing, using warm light is definitely a good option.
At the same time, such a yellow warm light is also more iron and the public's visual Xi to the outside world.
The white light of the LED lights visually gives people a "cold" feeling.
The "white light" emitted by the LED lights is closer to the light of nature itself, and the original appearance of the object can be restored.
Influenced by the original Xi, even the current LED lights have many benefits.
However, many people still choose to use traditional lamps instead of LED lights.
As consumers, we must consider many aspects when choosing lamps and lanterns.
The existence of LED lights gives us more possibilities, and also adds a touch of color to our lives.
When buying, we just need to maintain a rational attitude and look at all kinds of things.
