In our daily life, there are many inventions, including the wisdom of predecessors, such as telephone, computer, printing and so on. Among them, I think the most practical and greatest is the electric light invented by Edison, the "king of invention".
"Light" is an indispensable element in people's lives. Before the invention of electric light, people could only rely on natural light to illuminate the human body, doing it at sunrise and resting at sunset. Even if there are candles, oil lamps and other fire lighting, it still can't provide a stable light source, and it will cause a fire if used carelessly, which is quite inconvenient.
Once upon a time, people used kerosene lamps for lighting. The light of kerosene lamp is very dim and it has not been used for a long time. If they are not careful, they may cause serious accidents. However, the invention of electric light changed this situation, which not only filled the world with light, but also brought great changes to human life. When we do our homework, we protect our eyesight because of the lighting of electric lights. When looking for something, avoid taking the wrong thing because of the light of the electric light; When walking at night, we avoid danger because of street lamps, all because of electric lights. It prolongs the time available to people, and is safer and more convenient to design and use than firelight. So I think the electric light is the greatest invention in life!
Edison, the "king of invention", was able to invent the electric light, which was by no means accidental. He tried more than 1600 materials to find the material of tungsten wire, and it took countless failures to achieve today's results. This also proves that the only way to succeed is to stick to it!
The annual Zigong Dinosaur Lantern Festival was held again. I looked out of the window and saw the colorful lights in the garden embedded in the blue velvet night.
That day, my mother and I bought tickets to Lantern Park to see the annual Lantern Festival. Although it was extremely cold that day, the cold didn't seem to stop people from watching lanterns. As soon as I entered the park, I saw a sea of people in the garden, and the whole lantern corridor was full of people, like jiaozi in boiling water. My mother and I also squeezed in and became two "fat jiaozi". Looking from one end of the corridor to the other, we can hardly see the end of the crowd. My mother and I finally squeezed out of the "jiaozi Pot". Soon, my mother and I? Walking into the most beautiful Qinglong cup lamp area, all of them are small glasses, which are exquisite and incomparable. A few Qinglong mouths surrounded by cups are still spitting white gas.
The small lanterns on the roadside are also very beautiful, competing to open. As soon as colorful lanterns filled my eyes, they came one after another, attracting the red "five-pointed star" on the roadside, the "cockerel" with its head held high, and the cute little monkey ... What's more, look at the lively and lifelike phoenix with two big eyes like the night pearl.
There are also homemade lanterns sent by citizens, which are also very exquisite. As night fell, my mother and I left in the intoxication of lanterns, but the people watching lanterns were still in an endless stream. All kinds of lanterns shine like stars in the sky. It' s really "a night of lanterns and drunkenness, I only want spring to come."
And the lights in the pool. With the change of lighting and music, the fountain is red, yellow, blue and green, which is simply more beautiful than a rainbow. These colorful lights, flashing with street lamps, merge into a sea of lights.
Walking in the light brings happiness to people. ...
Lights are common industrial products in our lives, but if we are willing to exert our infinite wisdom and imagination and dare to do it, even lights will become diverse and interesting in the near future.
For example, the moon lantern is the crystallization of people's wisdom and imagination. Turn on the string lights at night, and you can see the crescent moon curved like a boat ahead, which can not only illuminate, but also feel the profound poetry of "the foot of my bed is so bright". How nice!
Have you ever wondered what it's like to have a sparkling balloon floating on the ceiling? There is no doubt that it must be like being in a dreamy fairy tale world. It's fascinating just to listen. As long as we have balloon lights, we don't have to just lie in bed and fantasize. Pull down the switch-the "balloon" line, and bang, the balloon lights up and emits colorful light. Seeing such light, all the troubles will vanish.
What power made mankind invent these novel lamps? Obviously, it is not enough to have Einstein's clever brain, but also to have rich imagination and the spirit of daring to think and innovate. Isn't it?
Lamp is a symbol of light and warmth, and it is an invention that can give people strength. Without the lighting function of the lamp, we can only fall into darkness every dark night and do nothing. Even if there is no moonlight, we can only wait for the sun to rise the next day, waiting for the light that the sun brings us. Think about it.
In addition to the role of lighting, I think lighting brings us color and happiness in life. In the evening, we went out to the noisy streets and squares. What we see is a world of colorful neon lights. The originally lifeless night, under the irradiation of a lamp, looks so vibrant and full of vitality, and the whole world becomes interesting because of the existence of the lamp. Under the action of the lamp, people can subconsciously, there is no difference between day and night, because at every moment of the day, we can do what we want.
The charm of light is really endless. Let's give thanks for this great invention.
