LED技术发展里程碑

LED技术发展里程碑1、LED发展历程1907年Henry Joseph Round第一次在一块碳化硅里观察到电致发光现象，由于其发出的黄光太暗，不适合实际应用，更难处在于碳化硅与电致发光不能很好的适应，研究被摒弃了。

20世纪20年代晚期Bernhard Gudden和Robert Wichard在德国使用从锌硫化物与铜中提炼的的黄磷发光，再一次因发光暗淡而停止。

1936年,George Destiau出版了一个关于硫化锌粉末发射光的报告，随着电流的应用和广泛的认识，最终出现了“电致发光”这个术语。

20世纪50年代，英国科学家在电致发光的实验中使用半导体砷化镓发明了第一个具有现代意义的LED，并于60年代面世。

第一个商用LED仅仅只能发出不可视的红外光，但迅速应用于感应与光电领域。

60年代初，在砷化镓基体上使用磷化物发明了第一个可见的红光LED，磷化镓的改变使得LED更高效、发出的红光更亮，甚至产生出橙色的光。

当时所用的材料是GaAsP，发红光(λp=650nm)，在驱动电流为20毫安时，光通量只有千分之几个流明，相应的发光效率约0.1流明/瓦。

到70年代中期，引入元素In和N，使LED产生绿光(λp=555nm)，黄光(λp=590nm)和橙光(λp=610nm)，光效也提高到1流明/瓦；就在此时，俄国科学家利用金刚砂制造出发出黄光的LED，尽管它不如欧洲的LED高效；但在70年代末，它能发出纯绿色的光。

80年代早期到中期对砷化镓磷化铝的使用使得第一代高亮度的LED的诞生，先是红色，其LED 的光效达到10流明/瓦接着就是黄色，最后为绿色。

到20世纪90年代早期，采用铟铝磷化镓生产出了桔红、橙、黄和绿光的LED。

在很长的一段时间内都无法提供发射蓝光的LED，设计工程师仅能采用已有的色彩：红色、绿色和黄色，早期的“蓝光”器件并不是真正的蓝光LED，而是包围有蓝色散射材料的白炽灯。

第一个有历史意义的蓝光LED也出现在90年代早期(日亚公司1993宣布，中村修二博士发明)，再一次利用金钢砂—早期的半导体光源的障碍物。

灯的发明英语作文The Invention of the Lamp: Illuminating Human ProgressIn the annals of human history, the invention of the lamp stands as a pivotal milestone, marking a significant leap in our quest for illumination and progress. From the earliest flicker of flame to the modern LED bulbs that light up our world today, the evolution of lamps has been a testament to human ingenuity and the relentless pursuit of innovation.The journey began with primitive forms of lighting, such as torches and campfires, which provided basic illumination but were limited by their mobility and safety concerns. It was the discovery of fire, arguably one of humanity's greatest achievements, that laid the foundation for more advanced lighting solutions.A crucial turning point arrived with the invention of oil lamps in ancient times. These lamps, fueled by animal fats or vegetable oils, offered a more stable and controllable source of light. They were instrumental in extending the hours of work and study, enabling civilizations to progress beyond the constraints of daylight. The ancient Greeks and Romans, in particular, refined oil lamp technology, incorporatinginnovative designs that improved efficiency and reduced smoke emissions.However, the true revolution in lighting occurred with the advent of gas lighting in the 18th and 19th centuries. The development of gas lamps, fueled by coal gas or natural gas, dramatically increased the intensity and duration of light. Cities across Europe and America began installing gas streetlights, transforming nightscapes and enhancing public safety. This technological advancement not only illuminated streets but also paved the way for more sophisticated lighting systems in homes and industries.Yet, it was the invention of the incandescent lamp by Thomas Alva Edison in 1879 that truly revolutionized lighting. Edison's lamp, which used a carbonized filament inside a vacuum-sealed glass bulb, was a game-changer. It was efficient, relatively long-lasting, and could be powered by electricity, making it a practical solution for widespread use. The incandescent lamp quickly became a symbol of modernity, illuminating homes, factories, and cities, and playing a pivotal role in the Industrial Revolution.Since then, lighting technology has continued to evolve rapidly. The 20th century introduced fluorescent lamps, whichwere more energy-efficient than incandescent bulbs, and the latter half saw the emergence of halogen lamps, offering brighter and whiter light. In recent years, the focus has shifted towards sustainability and environmental conservation, leading to the development of LED (Light Emitting Diode) technology. LEDs are highly efficient, durable, and eco-friendly, making them the preferred choice for modern lighting solutions.The invention and subsequent evolution of lamps have not only illuminated our physical spaces but also symbolize the illumination of human thought and progress. Each advancement in lighting technology has accompanied significant societal shifts, fostering education, industry, and cultural development. As we continue to innovate, seeking new and better ways to light up our world, the lamp remains an enduring symbol of human creativity and the relentless pursuit of a brighter future.。

电灯的发展史（Thehistoryofelectriclight）

电灯的发展史（The history of electric light）Before the advent of electric lights, the most commonly used lighting tools were kerosene lamps or gas lamps. This lamp burns kerosene or gas, so it has strong black smoke and pungent smell, and often add fuel, scrub the lampshade, so it is very inconvenient. What's more, this kind of lamp is easy to cause fire and cause disaster. For many years, many scientists have tried every means to invent a safe and convenient electric light.Light is a great invention of human conquest of the night. The inventor of the electric light made it bright. It was Edison, an American inventor. He was a child of a railroad worker who dropped out of school and sold newspapers on the train before he finished his primary school. Edison is an unusually industrious man who likes to do all kinds of experiments and make many clever machines. He was particularly interested in electrical appliances. Since Faraday invented the motor, Edison was determined to make the light and bring light to the human race.Edison in summing up previous manufacturing lamp failure experience, developed a detailed test plan, test was carried out in two aspects: one is the classification of 1600 kinds of different heat resistant materials; two is to improve equipment, the light bulb has a high vacuum degree. He also studied new types of generators and circuit branching systems.At the beginning of nineteenth Century, a British chemical household 2000 batteries and two carbon rods, made the world's first arc lamp. But the light is too strong to be installed onstreets or squares, and ordinary families can't use it. Countless scientists have racked their brains to create a cheap, durable household light.In October 21, 1879, an American inventor passed a long and repeated trial,The world's first practical light bulb was finally lit. From then on, the inventor's name, like his electric light, went into thousands of homes. He was praised by the later generations as "the king of invention" by Edison.In February 11, 1847, Edison was born in the town of Ohio, Milan, USA. He had only read three months in school, but he was diligent and diligent in thinking. His invention created more than 1000 kinds of achievements, such as electric light, gramophone, film camera and so on, and made great contributions to mankind.When Edison was 12 years old, he indulged in science experiments, through their own diligently to learn and experiment, at the age of 16, he invented the automatic telegraph to send a signal every hour. Later, the automatic counting machine was invented, the first practical typewriter, double and four heavy telegraph machine, automatic telephone and gramophone, etc.. Edison, who had these inventions, was not satisfied. In September 1878, Edison decided to launch an attack on the bastion of electric lighting. He went through a lot of books about electric lighting, determined to make cheap, durable, safe and convenient lights.He started experimenting with incandescent lights. Put a small piece of heat-resistant stuff in a glass bubble, and when thecurrent burns it to a white hot degree, it is heated. He first thought of charcoal, so he put a small piece of carbon wire into the glass bubble, just a power immediately broke."What's the reason for that?" Edison picked up the two section of the carbon wire, and then looked at the glass bubble, after a long time, suddenly remembered, "Oh, perhaps because there is air inside.",The oxygen in the air also helps the carbon filament burn, causing it to break off immediately!" So he used his hand for an air bubble in the glass removed as much as possible. It didn't turn off immediately. But 8 minutes later, the lights went out.In any case, Edison finally found that: the vacuum state is very important to the hot light, the key is carbon silk, the crux of the problem is here.So what kind of heat-resistant material should be chosen?Edison thought, the highest melting point, strong heat resistance to platinum! Then, Edison and his aides, with platinum tried several times, but the high melting point of platinum, although the light emitting time extended a lot, but from time to time to turn off the automatic automatic light, is still not ideal.Edison was not discouraged and went on with his own experiment. He has tried the barium, titanium and indium and other rare metals, the effect is not very ideal.After a period of time, Edison made a summary of the preceding experiment, wrote down all kinds of heat-resistant materials that he could think of, and there were 1600 kinds in all.Next, he and his assistants began experimenting with these 1600 heat resistant materials, trying to test them, or platinum. Due to the improvement of the extraction method, the vacuum in the glass bubble is higher, and the life of the lamp has been extended to 2 hours. But this is made of platinum materials made of light, the price is too expensive, who is willing to spend a lot of money to buy only 2 hours of light?The experimental work was in the doldrums, Edison very distressed, in a cold winter, Edison sit by the fire,Looking at the burning charcoal, the mouth can not help but automatic speaking: "carbon......"Do the available charcoal charcoal has been tried, how to do? Edison felt hot, shoving the neck scarf off, see this scarf with cloth is made of cotton, Edison's mind suddenly had an idea:Yes！ Cotton fiber is better than wood, can you use this material?He hastily tore a cotton yarn from his scarf and baked it on the fire for a long time. The cotton yarn turned into charred coke. He carefully put the carbon wire into the glass bubble, and the test proved to be very good.Edison was very pleased, and then made a lot of cotton yarn madeof carbon silk, continuous repeated tests. The life of the bulb was prolonged by 13 hours, and then 45 hours later.The news spread and caused a sensation throughout the world. The London gas stock price plunged, the gas line also appeared a mess. People have a hunch that lighting gas is about to become history, and that the future will be the age of electro optics.We have to congratulate Edison, lovely Edison did no happy appearance, shook his head and said: "no, I still have to find other materials!""Why, why not light up for 45 hours?"" Asked the assistant in surprise. "No! I hope it will last 1000 hours, preferably 16000 hours!" Edison replied.You know, it's good to shine for more than 1000 hours. What material can you find?Edison had a lot in mind. According to the nature of cotton yarn, he decided to look for new materials from the plant fiber.So, marathon trials started again.As long as the material of plants can be found, Edison has done experiments, even the mane of horses, hair and beard of people are used as filament test. Finally, Edison chose bamboo as a plant. Before the experiment, he took out a piece of bamboo and jumped up with a microscope. So, after the bamboo wire was loaded into the glass bubble, after the power, this kind of bamboo filament lamp has been continuously lit for 1200 hours!At last, Edison breathed a sigh of relief, and his aides congratulated him, but he said seriously, "there are a lot of bamboos all over the world, and their structures are different. We should choose them carefully!"The assistant was deeply moved by Edison's scientific attitude of excellence, and volunteered to visit them all over the country. After comparison, one kind of bamboo produced in Japan is the most suitable, and a large amount of bamboo is imported from japan. At the same time, Edison opened the power plant, erected wires. Soon after, the American people used this cheap, durable bamboo filament bulb.Bamboo silk lamp has been used for many years. It was not until 1906 that Edison switched to the tungsten wire to improve the quality of the bulb, which has been used today.When people turn on the electric light, they often think of the great inventor, who brings infinite light to the darkness. In 1979, the United States spent millions of dollars on a year long memorial to commemorate Edison's invention of the light bulb 100th anniversary.。

灯泡的发展历史作文

灯泡的发展历史作文英文回答：The history of the light bulb is a fascinating tale of scientific ingenuity and technological innovation. It all began in the early 19th century with the discovery of the electric arc. In 1802, the English scientist Humphry Davy passed an electric current through two carbon rods, creating a bright and intense light. This was the first electric lamp, but it was impractical for everyday use due to its high energy consumption and short lifespan.Over the next few decades, scientists around the world continued to experiment with different ways to create an efficient and long-lasting electric light. In 1835, the Scottish inventor James Bowman Lindsay developed a light bulb using a platinum filament. However, platinum was too expensive for commercial production.In 1840, the American inventor Thomas Edison joined therace to develop a practical incandescent light bulb. Edison experimented with different materials for the filament, including carbonized bamboo and cotton thread. In 1879, he finally achieved success with a filament made of carbonized cellulose. This light bulb had a lifespan of about 1,200 hours, making it the first commercially viable electric light.In 1880, Edison founded the Edison Electric Light Company, which began manufacturing and distributing light bulbs. Within a few years, electric lighting became widespread in cities and towns around the world. The invention of the light bulb had a profound impact on society, allowing people to work and engage in leisure activities after dark.In the early 20th century, the incandescent light bulb was further improved by the development of the tungsten filament. Tungsten is a stronger and more durable material than carbon, resulting in a longer lifespan and higher efficiency. In the 1930s, the fluorescent lamp was invented, which offered even greater energy efficiency thanincandescent bulbs.In recent years, LED (light-emitting diode) bulbs have emerged as the most energy-efficient and environmentally friendly option. LED bulbs use semiconductors to emit light, and they have a lifespan of over 50,000 hours.Today, the light bulb is an essential part of modern life. It is used in homes, businesses, and public spaces around the world. The invention of the light bulb has revolutionized the way we live and work, and it continuesto be an important part of our technological landscape.中文回答：电灯泡的发展史是一部科学创新的迷人故事。

The development of lamp and lightThe first lamp was invented around 70,000 BC. A hollow rock, shell or other natural found object was filled with moss or a similar material that was soaked with animal fat and ignited. Humans began imitating the natural shapes with manmade pottery, alabaster, and metal lamps. Wicks were later added to control the rate of burning. Around the 7th century BC, the Greeks began making terra cotta lamps to replace handheld torches. The word lamp is derived from the Greek word lampas, meaning torch.Oil LampsIn the 18th century, the central burner was invented, a major improvement in lamp design. The fuel source was now tightly enclosed in metal, and a adjustable metal tube was used to control the intensity of the fuel burning and intensity of the light. Around the same time, small glass chimneys were added to lamps to both protect the flame and control the flow of air to the flame. Ami Argand, a Swiss chemist is credited with first developing the principal of using an oil lamp with a hollow circular wick surrounded by a glass chimney in 1783.Lighting FuelsEarly lighting fuels consisted of olive oil, beeswax, fish oil, whale oil,sesame oil, nut oil, and similar substances. These were the most commonly used fuels until the late 18th century. However, the ancient Chinese collected natural gas in skins that was used for illumination.In 1859, drilling for petroleum oil began and the kerosene (a petroleum derivative) lamp grew popular, first introduced in 1853 in Germany. Coal and natural gas lamps were also becoming wide-spread. Coal gas was first used as a lighting fuel as early as 1784.Gas LightsIn 1792, the first commercial use of gas lighting began when William Murdoch used coal gas for lighting his house in Redruth, Cornwall. German inventor Freidrich Winzer (Winsor) was the first person to patent coal gas lighting in 1804 and a "thermolampe" using gas distilled from wood was patented in 1799. David Melville received the first U.S. gas light patent in 1810.Early in the 19th century, most cities in the United States and Europe had streets that were gaslight. Gas lighting for streets gave way to low pressure sodium and high pressure mercury lighting in the 1930s and the development of the electric lighting at the turn of the 19th century replaced gas lighting in homesElectricity lightEdison inventing the light bulb did not 1500 many experiments to find suitable lamp filament material, it was ridiculed, he said: "Mr. Edison, you have failed in 1500 many times." Edison replied: "No I have not failed, I have done is found in more than 1500 kinds of materials are not suitable for the filament lamp. "After further testing, Edison found that the Japanese use bamboo charcoal for the best filament. Until 1906, Edison has to do to switch to tungsten, so that the quality has improved light bulb, has been in use to this day.。
