Efficient Lighting
Introduction:
There have been many electric light bulbs made in the world, all using different amounts of electricity, some better then others. Today we have the choice between many, but it all started with the first electric light bulb invented by Humphry Davy in 1800. Since then many more have been made and we have the best use of light there ever was today.
A light bulb is a glass envelope that provides light by passing an electric current through a filament. The filament creates the energy that makes the light show.
Light bulbs are used daily in almost every room and building in the U.S.A. They are essential to our daily uses. We use extreme amounts of energy each day to keep our homes lit.
Problem:
Today we are faced with many choices of light bulbs and we all want to say money on the amounts of energy we used. “Electric lighting burns up to 25% of the average home energy budget.” What light bulbs are the best to buy, to save the most amount of electricity we use each day? We are given too many options, how do we know what is the best? There are hundreds of different light bulbs we can buy, there are 271 results for just the LED light bulb, and that is only one type of bulb.
Type of Bulbs:
1. Incandescent light bulbs: These light bulbs have a very thin tungsten filament. The filament is what gets very hot from the electricity, which runs through it. The heat that is produced creates “white” energy, which is visible light. The problem with these bulbs though, is that the heat wastes a lot of electricity. The incandescent light bulb produces 15 lumens per watt of input power. This light bulb was made in 1802 and still used today. It has both advantages and disadvantages to using it. Great for small area li...

...hts. If this is the case, then why are they not the most common light used today? The answer to this is that the cost of the LED bulbs is not economically due able for more people. Incandescent light bulbs have been around for so long, because they work and are cheap. They do the job, but are it most efficient. For most people though efficient is not their main concern. Therefore, today there is still a large variety of the light bulbs that are purchased and which of them is their preference.

For new or retrofit construction, every choice can lead to energy savings; energy that is derived primarily from fossil fuels. The typical household LED replacement for a 60w light lasts about 50,000 hours. Pretending that an incandescent could also last that long, it would consume about 3,000 kilowatt-hours (kWh) of energy whereas the LE...

Candles in varying colours, shapes and sizes are still manufactured and used in different manners like in religious ceremonies, birthday celebrations, aromatherapy, and home decorations.
The light bulb changed how we lived now. Thomas Edison invented the light bulb, as he grew up he was learning so much knowledge for chemistry and electronics, and his 40 years of research to get the light bulb to work. Thomas Edison is an inventor of major technology. Threw his years he had studied many books by his parents and been reading many books on chemistry and electricity. The more he grew up he started to pursue his education on chemistry and electronics for many years. The more he tried to invent things he had help making of the light bulb with a group of scientists. Thomas Edison is the one who made the light bulb become possible by pursuing more education.
He worked with George Westinghouse and Nikola Tesla during the late 19th century so bring electric lighting into houses and offices. Incandescent lighting is when light is produced by heat. Around 1870s, there was already lighting called arc lighting. Those were placed in large indoor rooms such as a stage and outdoors in streetlight lamps. Arc light was proven to be impractical in housing or offices. During the 1879, Edison did research in an entire electrical systems which would deal with a generator, a distribution system, and a light bulb. His main focus though was the light bulb. It needed to be strong enough so that the heat wouldn 't cause the light bulb to explode. He worked with carbon filaments which burned inside a glass globe as electricity flowed through the filaments. During the same year, Edison worked with Francis Upton to make a generator that produced direct current, which is also what Edison is very well known for. Direct current was used for incandescent

the bulb burns out. The filament of a bulb is a very thin wire and
Instead, most of his inventions were made using electrical energy. In 1878 he dedicated almost two and half years of his life to invent incandescent electric lighting. He was granted a patent for the famous light bulb in 1880. That same year he founded the Edison Illuminating Company and then left Menlo Park to travel around the globe. He visited different cities, offering his consultation services to local union councils and electrical companies on how to implement electrical systems.
The light bulb is the way we see in the dark, the way we find our way, the way we know when to go at a stoplight. How did Thomas Edison achieve this invention? Knowledge. Knowledge of electricity and the needs of those around him. In The Great Gatsby, Daisy Buchanan claims that she wants her daughter to be “a beautiful little fool.” In other words Daisy is saying that ignorance is bliss. Some others believe that knowledge is power. The advancement from candles to light bulbs changed the culture entirely. People could easily do the work they needed to after sunset, and it even led to more inventions. We need knowledge to advance, and for this reason powerful knowledge is more valid than blissful ignorance.

...also save energy by using motion censoring for doors and sinks. The dining rooms and foyers should have dim-able light switches. Another way to save a lot of energy is to make a master switch at the front door that turns off all lights. That way you never leave a light on when you aren't at home. You should use natural gas cook tops and ovens to cut down on electricity.
In 1879, after spending $40,000, and performing 1,200 experiments, he succeeded. He made a light bulb using carbonized filaments from cotton thread. Carbonized thread is ordinary cotton sewing thread that has been burned to an ash. The light bulb burned for two days. The electric light took the greatest amount of time and required the most complicated experiments of all his experiments.
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
Light bulb is one of the most influential inventions in the word. It makes us work more productive at night and helps us enjoy more activities at night. It significantly change people lives all over the world. The born of light bulb also helped us by making more inventions that related to light, such as phones, televisions, and computes. By using light bulb, we actually reduced the probability of having fire accidents because if we don’t have light bulb, we will use candles instead which can cause fire easily. There are a lot more benefits we get from light bulb, and all of these are credited to Thomas Alva Edison.

He starts to investigate how to create a light bulb that can last longer. Before Thomas Edison started making the light bulb, there were other inventors working on it, but no one could let the light bulb work longer. Eventually, on October 21, 1879, Thomas Edison’s light bulbs could work for forty hours. Thomas Edison and his team try to use the incandescent light bulb in the laboratory and at home. In 1880, Thomas Edison believed the incandescent bulbs could be produced and sold to the public.
