Have you ever wondered were led lights came from..? well I Daniel Mcfarland was born in Pennsylvania on February, 27 1869 and attended Lehigh University for college from 1884-1889. I studied electrical engineering, After experimenting with different sources, I started using glow discharges to produce light. In 1986 I had devised a glow discharge lighting system, creating an extension to the Geissler tube. The lamp utilized nitrogen and carbon dioxide as the luminous gas because they emitted a soft white light. My technique was the first commercially variable light source based on gas discharge instead of incandescence, and it's considered the predecessor to contemporary neon and fluorescent lighting.
The light emitting diodes (LEDs) are low energy, lighting devices with a long lifespan and low energy consumption. The LEDs use specialized power
Glow sticks, like many other everyday items, have chemistry involved with them. Glow sticks were discovered by Edwin Chandross in the 1960s. He was a young chemist at Bell Labs in Murray Hill, New Jersey. Edwin Chandross actually discovered the glow stick on accident. All along he was just trying to find a general way to explain chemiluminescence. By mixing florescent light and hydrogen peroxide with oxalyl chloride, he discovered how to create a glowing chemical light. From Chandross original discovery a lab team called American Cyanamid, led by Michael M. Rahurt, created an oxalate ester named phenyl oxalate to replace the oxalyl chloride. This lab team then sold their new product to a group named Omniglow who went
In the industrial revolution Gas lighting was one of the most helpful thing that was ever invented, the person that invented gas lighting was The Scottish inventor William Murdock he first invented gas lighting in his hometown in england in 1792 then he installed gas lighting in an English factory in 1798 but by that time the streets of London, Paris, Baltimore, and the united states were lit with gas lights.
The use of gas as iluminant became widely available with the invention of the Dalen Light by Swedish engineer, Gustave Dalen. In 1906, Dalén became the chief engineer at the Gas Accumulator Company.. Initially Dalén worked with Acetlyene, an extremely explosive Hydrocarbon gas. Dalén invented something called Agamassan, which is a substance used to absorb the gas allowing safe storage and hence commercial exploitation. Acetylene produced an ultra-bright white-light an as the fuel of choice in lighthouse illuminations. Dalén incorporated another invention into his light. This device allowed the light to operate only at night, conserving fuel, and extending their service life to over a year.
The incandescent light bulb was a phenomenal discovery that occurred during the late 1800’s and was mainly invented by a man named Thomas Edison. It became a recent essential product that we humans use on a daily basis in many more appliances than one. This invention was created in 1890 in New Jersey by Thomas Edison to help people to be able to work during the night after night had fallen and to make people’s lives easier ("Edison's Lightbulb”). It helped many people in an amazing array of different ways, however, everything has it’s disadvantages, and so did the incandescent light bulb ("History of the Incandescent Light.”)
When the first modern light bulb that ran on electricity was created by Thomas Edison who had the invention to be patented in his name on January 27, 1800(Thomas Edison's Patent Application for the Light Bulb (1880) para. 1), people finally had a way to light their homes
In 1879, he created his first ever high resistance incandescent electric light. The way it worked would it passed electricity through a thin platinum filament in the glass vacuum. Which that kept the filament from melting. The reason it didn't work is because it only lasted a few hours. Even though it was closer to the light bulb used today there was still a few improvements to be
This rudimentary bulb consisted of a piece of carbon which glowed when wires were connected from it to an electric battery. Although the light bulb was not truly invented by Thomas Edison in 1879, he is credited as the inventor and is said to have created the first commercially practical incandescent light. Bulbs play a huge role in our everyday lives, and are also incontrovertibly important in the theatre. As an actress and makeup artist, I have to be able to stand out to others; therefore, I give one hundred percent effort to every activity in which I take part. This vital part of the spotlight represents me because I always seem to shine to my fullest potential. Marianne Williamson - an American spiritual teacher, author, and lecturer - and I seem to think a lot alike. She believes when we let our own light shine, “we unconsciously give other people permission to do the same.” The bulb does the main part of projecting the beam, yet barn doors seem to help as
So one of the things that was invented that have been reinvented is a traffic light. The traffic light was invented in the 1920s by an inventor named William ports. He used the three main colors green, amber, and red. The first traffic light was put
Loie Fuller invented pieces of theatrical lighting equipment. She created a unique art form by crafting multi-media spectacles out of fabric, motion and light. In Fuller’s autobiography, she talks about how the glass of the rose windows in the great cathedral had rays of sunlight that came on into the church in different directions, and made it very colorful. I think this is a moment that inspired her. It was something that caught her attention, and she just couldn’t simply take her mind from it. This was something that encouraged her to keep digging into the things lights and colors can do in dance. In one of her videos, it shows her twirling her dress in many different ways while her dress is also changing colors. This was very unexpected for me. It was different and it made me think about the things she had to do to make this idea into a creation. I was also able to see how the lights reflecting in the church inspired her because the color of her dress kept changing as she twirled so smoothly. It was very settle and something you wouldn’t usually notice right away like the lights in the church. In the reading, she states, “What is the dance? It is motion. What is motion? The expression of a sensation. What is a sensation? The reaction in the human body produced by an impression or an idea perceived by the mind. A sensation is the reverberation that the body receives when an impression strikes the mind.” (Fuller, 17). She is explaining the thought process that she goes
Then, in 1951, another scientist Morris Grodsky, blended powder forms of the chemicals luminal, sodium carbonate, and sodium perforate in distilled water. This is basically the spray used in CS I kits and present day. This solution post a problem because of the sodium perborate. It contradicted with the hemoglobin oxidizing the luminol. This slowed the reaction. The glow was not bright and only lasted a short period of time, it was unstable and even toxic, it must be stored in a cool space, couldn't come in contact with directly, expired quickly, and if it was photographed it must be completely dark or one had to film it with a night vision camera.
These Litake Submersible LED Lights are a much-needed accessory for your next outdoor party. When you're decorating, it's easy to miss lighting as part of your scheme. Yet, lighting can be an incredible asset to really take your décor to the next level. We absolutely adore lights for all kinds of occasions and even for times when it's just a few close friends in the backyard.
In Holland, Gerard Philips started a light-bulb factory with his father in 1892. Later, Gerard’s brother, Anton, joined them adding his experience in sales and management. The Philips’ family run business eventually grew to be one of the largest European light-bulb producers.
I was born on July 9, 1856 to a wonderful family near Smiljan, Croatia. As a young boy, I was fascinated with lightning storms and the power of water in rivers and streams. After seeing a picture of Niagara Falls, I vowed to put a water wheel under it to create power. I read a lot and I was inspired by many of the inventions I discovered in literature. Eventually, I moved to Budapest where I scraped by until the Central Telegraph Office opened where I was hired immediately. From the job, I began to learn who Thomas Edison was. I learned that he was a revolutionary scientist in America who had invented unfathomable creations. Thomas Edison had been using Direct Current (DC) to power America, but I wondered what the possibilities were
Many centuries ago people did not need much energy. Back then, people used the sun or burned wood and straw for heat. People used the wind force in sails or horses to go anywhere in the world and used animals to do the work humans could not do. Although, humans did use simple machines that could ground grain, pump water, and even utilize steam power. Steam engines transformed over time and by the 18th century the modern steam engine, fueled by coal, could do the job of a team of horses. Since steam engines were much more favorable compared to air and wind power, steam engines were used to power factories and coal was used to heat up buildings.
