Since the white LED lamp was invented in the 1990s, it has gradually replaced the incandescent lamp and become the necessary lighting supplies for every household. The biggest reason why LED lights could replace incandescent bulbs was their energy efficiency, a much-touted feature that led to their rapid demise.
Now, except in some special places, incandescent lamps are seldom seen. But numerous tiny partners found that since the use of LED lights, their electricity bills are not less, but more, and frequently out of the problem. Why is this? So here's the 4mm led strip light.
1. The birth of General Electric under the incandescent lamp
Before the invention of the incandescent light bulb, only candles and kerosene lamps were used to light the night, but this was not a luxury that ordinary people could commonly use. I don't know if you remember, we all learned when we were kids, but Edison invented the light bulb.
But in fact, numerous people before him had discovered that electricity emits light. The pity is that neither David, an English chemist, nor Henry, an American. Goebbels did not apply for a patent. It wasn't until 1879 that Edison perfected the light bulb technology and made it genuinely successful in every home. It was the technology that allowed Edison to enter the elementary school textbooks of our country. And this technology brought Edison great wealth.
Many people do not understand that the famous American General Electric Company was founded by Edison, when he left his three children with about $12 million - $18 million wealth. At its peak in 2000, GE was valued at approximately $600 billion. Ge is still worth more than $80 billion.
2. Trillion yuan market scale
The incandescent light bulb has been around for 143 years since it was modified by Edison in 1879, breaking the darkness of the night for thousands of years. To a certain extent, it has extended the available time of mankind and created enormous wealth for the whole world.
China is a huge consumer of incandescent light bulbs. According to statistics, 12 percent of China's annual electricity generation is consumed by incandescent light bulbs, while the photoelectric conversion efficiency of incandescent light bulbs is only 2 percent. This has also forced the market to demand a lighting appliance that is more efficient and energy efficient than incandescent bulbs.
Eighty-three years later, it was General Electric that invented the LED light in 1962. The LED light is essentially a light-emitting diode, which is a kind of semiconductor material that emits light through an electric current. The initial use of this product is as a signal indicator. It was later discovered that the product had a stronger photoelectric effect and was brighter. Gradually began to be used in signal indicators, lighting systems, screens.
China is a huge industrial country and also the LED industry. According to statistics, the overall industrial scale of China's LED industry in 2017 is 636.8 billion yuan, compared with the overall industry scale in 2016, an increase of 21%. The LED lighting market accounts for more than half of the overall LED scale, reaching 301.7 billion yuan in 2016.
By 2020, the scale of the LED lighting market alone reached 526.9 billion yuan. In 2021, the total scale of LED industry will reach one trillion yuan, and the LED lighting market will also reach 580 billion yuan.
Third, energy saving is not electricity saving.
In 2017, China's annual electricity consumption for lighting accounted for about 12% of the total electricity generation. According to the calculation at that time, if all incandescent lamps were replaced by LED lamps, 48 billion trillion hours could be saved every year. But now several years have passed, incandescent lamps have nearly disappeared, but the proportion of lighting electricity in the total electricity is still about 10%, there is no obvious change.
This can not help but cause the question, do LED lights truly save electricity?
In fact, leds do use less power than incandescent bulbs. Incandescent bulbs convert more of their electrical energy into type 2 heat than light because of the way they emit light. Leds are 10 times more energy efficient than incandescent bulbs, meaning they use only 1/10 of the power loss of incandescent bulbs for the same amount of light. Leds are really extremely energy efficient.
Then why do you have the illusion that the electricity consumption of the home will rise after the use of LED lights?
First of all, the shift in the use of habits, because the family is poor before, everyone has a strong sense of saving electricity, in the use of lamps and lanterns can save the province; it IS NEXT AS LIVING STANDARD UNCEASING RISE, THE HOUSEHOLD APPLIANCE IN THE HOME IS INCREASING CEASELESSLY, FROM BEFORE EACH ROOM HAS A BULB ONLY, ARRIVE NOW A SITTING ROOM TWO OR THREE BULBS.
In order to lovely some people's living room is not only these, but also increased a lot of ornamental lamps and lanterns, but also inadvertently increased the consumption of electricity, which makes you feel that the use of LED lights after additional electricity.
Four, is your LED not frequently broken?
Publicity life of more than 100,000 hours, buying a lifetime of LED lights can be used. Why is it always broken every once in a while? In fact, a lot of times it's not the LED light that's broken, it's the LED driver that's broken.
The LED light itself is a light-emitting diode, which requires a conversion device that converts alternating current (AC) to steady direct current (DC) in the home. This device is called a driver. The life of the drive itself is not compared to the LED light, and it has higher requirements for the working environment, the LED light can work in the environment, the driver is not.
On the other hand, due to the LED light production environment requirements are extremely strict, the need for strict dust-free workshop, but numerous manufacturers of the factory are not qualified, which leads to a lot of LED in the factory itself having hidden dangers, which is why the same LED, some tens of dollars, some up to hundreds of dollars. It's also the reason why household LED lights frequently break down.
conclusion
Now the LED industry is not only a lighting industry, but also a huge industry involving screens, signalers, lighting, electronics and so on. LED lighting is only one of its markets, but in this industry, our country does not occupy great advantage. Do you feel that in the future, our country's LED industry can walk to the forefront of the world?
