LED lights are "short in life and consume electricity". Why do businesses claim that they are energy-saving products?

The biggest reason why LED lamps can replace incandescent lamps is energy saving, which was widely publicized by businesses at that time

Now, except for some special places, incandescent lamps are rare. But many children find that since they use LED lights, their electricity bills are not less, but more, and they often have problems. Why?

1. Under the incandescent lamp, the birth of General Electric Company

Before the invention of incandescent lamps, only candles and kerosene lamps could be used for lighting at night, but this was not a luxury that ordinary people could often use. I don't know if you can remember. We all learned it when we were children. It was Edison who invented the light bulb.

But in fact, before him, many people have found that electricity can emit light. Unfortunately, neither David, a British chemist, nor Henry Goebbels, an American, applied for a patent. It was not until 1879 that Edison improved the bulb technology, which truly enabled this technology to successfully enter millions of households. It was this technology that gave Edison the opportunity to enter our primary school textbooks. This technology also brought Edison great wealth.

Many people do not know that Edison founded the famous American General Electric Company. At that time, he left about $12 million - $18 million of wealth to his three children. In 2000, GE's market value was close to $600 billion at its highest. Today, GE still has a market value of more than 80 billion yuan.

2. Market size of trillion yuan

Since it was improved by Edison in 1879, incandescent lamps have a history of 143 years, breaking the dark nights of thousands of years. To a certain extent, it has extended the available time of human beings and created huge wealth for the world.

China is a big consumer of incandescent lamps. According to statistics, 12% of China's annual power generation is consumed by incandescent lamps, while the photoelectric conversion efficiency of incandescent lamps is only 2%. This also forces the market to urgently need a lighting appliance, which is more efficient and energy-saving than incandescent lamps.

In 1962, 83 years later, GE still invented the LED lamp. In fact, the LED lamp is a kind of light emitting diode, which is a semiconductor material that can emit light through current. This product is used as a signal indicator in the initial use. Later, it was found that the photoelectric effect of this product was stronger and the brightness was higher. Gradually began to be used in signal indicators, lighting systems, and screens.

China is a big industrial country, and also a big LED industry country. According to statistics, the overall industrial scale of China's LED industry in 2017 was 636.8 billion yuan, an increase of 21% compared with that in 2016. The LED lighting market accounts for more than half of the overall LED scale. In 2016, the LED lighting market reached 301.7 billion yuan.

By 2020, the scale of LED lighting market alone will reach 526.9 billion yuan. In 2021, the total scale of LED industry will reach trillion yuan, and the scale of LED lighting market will also reach 580 billion yuan.

3. Energy saving is not power saving

In 2017, China's annual lighting power consumption accounted for about 12% of the total power generation. According to the calculation at that time, if all incandescent lamps were replaced by LED lamps, 48 billion hours could be saved every year. But now, a few years later, incandescent lamps have almost disappeared. However, the proportion of lighting electricity in the total electricity consumption is still about 10%, and there is no significant change.

This can not help but arouse the question of whether LED lights really save power?

In fact, LEDs do save electricity compared to incandescent lamps. Because of the different principles of light emission, incandescent lamps convert more electric energy into Class II heat energy rather than light energy. Compared with incandescent lamps, the energy efficiency of LED is 10 times that of incandescent lamps. That is to say, under the same light intensity, LED only needs to use 1/10 of the power loss of incandescent lamps. In fact, LED is very energy-saving.

So why does everyone have the illusion that the use of electricity at home is rising after using LED lights?

The first is the change of usage habits. In the past, because our families were poor, we all had a strong sense of saving electricity, so we could save on the use of lamps and lanterns; Secondly, with the continuous improvement of living standards, the number of household appliances at home is increasing, from only one bulb in each room to two or three bulbs in a living room.

In order to beautify the living room of some people, many ornamental lamps have been added, which also inadvertently increases the power consumption, which makes people feel that after using LED lamps, they use more power.

4. Is your LED often broken?

The publicity life is more than 100000 hours. Why does an LED lamp that can be used for a lifetime always break every once in a while? In fact, most of the time, it is not the LED light but the driver of the LED light that is broken.

LED lamp itself is a light-emitting diode, which requires a conversion device to convert household AC power into stable DC power. This device is the driver. The life of the driver itself is not as long as the LED lamp, and it has higher requirements for the working environment. The LED lamp can work in the environment, but the driver cannot.

On the other hand, due to the strict production environment requirements of LED lights, strict dust-free workshops are required, but many manufacturers' factories are not qualified, which leads to the hidden dangers of many LED lights when they leave the factory. This is why LED lights also cost dozens of yuan, and some as much as hundreds of yuan. It is also the reason why household LED lights often break down.

Now LED industry is not only a lighting industry, but also a big industry involving screen, annunciator, lighting, electronics, etc. LED lighting is only one of its markets, but in this industry, China does not occupy too much advantage. Do you think that in the future, China's LED industry can go to the forefront of the world
