Transcript: Hiram Maxim The first light bulb had a round shape with a little hump on top and it had to be attached to an electric lamp. References http://www.livescience.com/43424-who-invented-the-light-bulb.html https://en.wikipedia.org/wiki/Thomas_Edison Joseph Swan http://www.bulbs.com/ Thomas Edison is usually credited with the invention of the light bulb, but Edison wasn't the only one who contributed to the development. Many notable figures are also remembered for their work, Joseph Swan & Hiram Maxim. Is the Light bulb still used today? Of course, The light bulb changed the world in many ways, changing society for the better, making it brighter. It also brought other appliances into the home. Such as the oven and microwave. What most people and myself didn't/don't know Edison didn't design the light bulb independently, he perfected the early versions with the combination of three factors an effective incandescent material, a high vacuum, and high resistance that made power distribution. Edison is often credited with the invention because his version was able to outstrip the earlier versions other scientist produced light, but it didn't last long and was much to bright for practical use. Inventors were continuing to make small advances, improving the filament manufacturing process and efficiency of the bulb. The light bulb is an electric lamp with a carbon filament. Scientist were trying to invent a way to use electricity to light your house the old style of lighting candles, lamps, and lanterns were dangerous. They caused plenty fires back then. Back in 1878-1880. Thomas Alva Edison http://energy.gov/articles/history-light-bulb Edison and his research team in Edison's laboratory in Menlo Park N.J. tested more than 3,000 designs for bulbs between 1878 and 1880. What was the Light bulb shaped like? What is the Light bulb? Where was the Light bulb designed? Edison did not design the Light bulb.
Transcript: Light Bulbs The differences between Florecent and Incadecent light bulbs are that the incandecent bulbs makes light by heating a metal filament wire to a high temperature until it glows, which uses a lot of electricitie. Florecent bulbs use electricity to excite mercury vapors inside the glass. Then theres a short-wave of ultraviolet light that makes a phosphor to fluoresce, producing visible light, which use less energy because it doesnt have to create heat. A florecent light that has 9-12 watts has the equal amount of light output as a 40 watt incandecent light bulb. Compared to a normal incandecent light, the florencent light bulb will save up to 30$ in the bulbs lifetime, will la ten times longer.
Transcript: - Lightbulbs consists of a glass closure and within it is a tungsten filament which energy passes through it which produces heat and then light Danger - My prediction is that without light bulbs we will only be able to do things when it's day time. - We would also have to use other sources or light like candles or oil lamps. - Light bulbs are used commercially and for residential purposes. Light bulbs are sold everyday in life and light bulbs are used in residential areas and in commercially owned studios. (street lights, light fixtures, etc.) Benefits How does it work? - There is a type of bulb called compact fluorescent lights (CFL) which contains mercury that can poison or become a danger when exposed to History By: Eriyan Barrett Prediction - In 1802, the first light bulb was created by Humphry Davy. - It was said that Thomas Edison created the first light bulb but that is because his version was able to outstrip the earlier versions Lightbulbs Pictures Commercial or Residential - There are energy efficient lightbulbs that saves energy and money - Light bulbs create light which is used everyday to light up rooms Logo
Transcript: A common mis conseption of light bulbs is that they were invented by Thomas Edison.This is not true The inventor of the lightbulb is really Hiram Maxim light bulbs misconseption good bye inventor how does An incandescent bulb uses heat caused by an electrical current. When electrical current passes through a wire, it causes the wire to heat. The wire, or filament, gets so hot that it glows and gives off light. Everyday incandescent light bulbs have a filament made of tungsten. ligt bulbs help in many ways
Transcript: While the incandescent bulbs remain the cheapest, CFL lights come in next ranging at about 10$ a box. LED's are the most expensive, prices going up to 36$. What we Use CFL and LED After asking around, we discovered that Chef Cole and the others who do any sort of purchasing, aren't really concerned when it comes to lights. The cheapest is the best. Cheap incandescent lights for the hood vents, the specific projector bulbs, and whatever we can lay our hands on for everything else. CFL lights are probably the most recognizable bulbs, with the twisted bulb. Typically, they can last between 6,000- 15,000 hours. 10,000 is the average. That boils down to 5,976 days, or a little more than 16 years In our Bradford School, we use regular incandescent light bulbs. Joe and I have been researching various lights that might result in the conservation of energy, as well as money for our school. LED lights are more complicated and scientific but they are even more efficient than CFL lights. The maximum life span of an LED light is 50,000 hours, or 11 years if 12 hours a day Regular incandescent lights last a short amount of time and need replacement often. On average, 750-1000 hours, which in comparison, is a very short lifespan, just over 40 days at most. Price Joe Canzano And Jennifer Oswald Light Bulbs!! Regular incandescent bulbs typically use about 60 watts, which would make the kilowatt/hour per year significantly higher than these low watt bulbs How long do those last? Should We swtich? CFL: lights use a little less, ranging at about 6-8 watts, and resulting in about 630 kilowatt/hours per year. Other Options Obviously, incandescent lights are not the only option out there. In terms of energy saving, there are two other extremely popular options. CFL- Compact Fluorescent Lamp, and LED- Light Emitting Diode. Energy Usage LED lights use about 13-15 watts, in turn using roughly 760 Kilowatt/hours per year. Heck yea we should! To start with, the LED and CFL lights would be more expensive, but because you wouldn’t have to buy them nearly as often, the end result is much cheaper than regular fluorescent light bulbs. Also, the lower wattage would result in a much cheaper electric bill. Intro
Transcript: Barbara Cooper Lauren Diaz Samantha Baum Tony Patterson Johnathan Harper Information On The Bulbs Let's Focus On Two Bulbs' Functions Parts Of The Bulbs. History On CFLs & Incandescent Compact Flourscent Characteristics Incandescent Compact Flourscent Dear Legislator, These are the ups and downs of whats going on with all these light bulb things that are changing as we are going into the next moments of our lives. Why they can be dangerous and kill someone. Also why they could be better, but i would be against it. Calumet New tech High School freshman's class for science has been working on the deference's between the old and new light bulbs. Like how much they cost how much money you would save if you switch, also how to make the world more efficient. But why are you making the grown ups have to buy more expensive light bulbs what if they can’t afford them then that was not right. To also say one more thing i could careless about what light bulbs we use. My name Is Jonathan Harper, freshman. Even though if you buy the newer light bulbs in the future you will save a decent amount of money which is cool. Lights are brighter but very dangerous if you break it open which could be a problem, why would they create a light bulb that can hurt or worse kill someone. But their is a better side like the money that you will save can buy new things for their family. I would vote against it because i don’t want to break one while i’m sleeping and die in my sleep with the older ones they weren’t dangerous and not bright but at least you felt safe in you house at worst if they break you would get cut by glass. Yes i sound negative but i am just trying to be honest. . These lights should be used where brief illumination is needed, like in a closet. Bulb Hazards The Electric Light Bulb Was Made In 1879. Light Bulbs Each kind of light has a use. Let's get more into detail Gas Cons: Health Issues Here We Go Background Information Compact Flourscent Unwanted Heat. Hazardous. There are several main kinds of lights Flourscent Pricey The End Health Issues Tubes LED Lead-in Wires Flourscent Incandescent Thomas Edison Hazardous Bad For On/Off Cycling Stem Press Low Pressure Sodium Incandescent Halogen Button Halogen Hazards Thomas Alva Edison was the inventor of the light bulb. Hazardous Incandescent Light Bulbs On To The Next One Cons: Short Life Span Expensive Fuse Uses & Pros : The brightness of the ligh reduces eyestrain for reading. Used for display lighting to show off artwork, statues, ect. Best for outdoor use. The CFL lights are not as bright as the old ones, but have many more pros than the incandescent bulbs. Letter to a legislator Uses & Pros Being used nationwide Cons: The flourscent coating on the bulbs, can cause eye damage, & has also caused other negative health effects. Uses & Pros : Last up to 10 times longer than incandescent. Generates Little Heat Does not contain mercury Uses Less Energy Used on truck tail lights. Being used now because government is banning incandescent lights from being used for various reasons. Uses Significant Amount Of Energy Poor Quality Brightness changes on room temp. Inventor: Intense Glare. Their lifetime lasts best when it comes to on/off cycling. Peter Cooper Hewitt/Edward Hammer CFL bulbs operate at lower temperatures than incandescent bulbs. Many fires have been caused by high wattage incandescent bulbs in ceiling fixtures melting insulation on wires, Thanks For Watching Intense Glare Heat Deflector Uses & Pros : Long Life Span Uses Less Energy Bright Button Rod Easy installation & clean up : High Intensity Discharge Not expensive & easy for Americans to purchase Expensive Base Tie Wires LED Extremely Hot. Although, smoke be emitted from CFLs because of melting plastic, it's normal. Their lifetime lasts best when it comes to on/off cycling. Just like the incandescent light bulb, it contains mercury, but less than the incandescent light bulb Compact Flourscent Light Bulbs Filament Compact Flourscent Inventor: Support Wires Uses & Pros : Long Life Span Low Energy Consumption Low Fixation Costs. Cons: Cons: Incandescent Fire Hazards
Transcript: History of the Light bulb It begun in the early 18oo's . When light in homes consisted of oil lanterns, candles, and gas lamps. Then in 1809 Humphrey Davy, a British chemist began the idea of an incandescent light bulb. He simply used a high power battery to create a current between two charcoal strips creating an intence incandescent light In 1820, Warren De la Rue used a platinum coil in a vacume sealed tube and ran an electric current through it to make an incandescent light bulb, this was the first attempt ever. . . .
Transcript: Fluorescent & LED Light Bulbs Incandescent light bulbs is the light bulb commonly used in homes, however isn’t as energy efficient compared to other light bulbs. It is also less expensive and causes an inviting and warm quality over its setting. Very complimenting to skin tones and psychologically appealing. lasts within 700 to 1,000 hours Halogen Bulbs . Are a variation of incandescent light bulbs. Gives off light known as “white light” because the kind of light they project are the closest to natural daylight compared to other light bulb options available. Compared to incandescent bulbs they a more energy efficient however, are more expensive and burn at a higher temperature. Halogen light bulbs are commonly used in under cabinet lighting, pendant lights and recessed cans. Humphry Davy-->Was the first scientist in 1803 to create the arc lamp. He created this lamp using volts from a battery. This produced light greater than one thousand candles. James Bowman Lindsay-->Was the first person in 1835 to contain an electrical charge inside of a glass bulb. Although his creation was highly unreliable during the time it was still a major contribution to Edison’s creation of the electric light bulb. Paris, France-->Although Paris, France is a city it did however perform something that was unconventional and unthought-of at the time; it attempted to light their streets with electric street lamps in 1841. They performed this using Humphry Davy’s Arc Lamp. Heinrich Geissler-->Created a special tube to use with electricity in 1856. This tube called The Geissler Tube contained an electric charge, and it paved the way for neon and other types of lighting. Thomas Edison-->He made a lamp in 1879 and followed it with the creation of a 16-watt light bulb in 1880. Nikola Tesla-->He worked with Edison however branched off to work on creating a wireless electrical lamp in 1893. Paris, France-->Paris continued to set the stage for electrical advances. They premiered the neon lighting, created by Georges Claude, at the Paris Motor Show in 1910. Edmund Germer-->Created a lamp for fluorescent lighting in 1926. The Philips Company-->They created a fluorescent energy saving lamp in 1981. However, wasn’t popular in a middle class home at the time because of the price tag. In 1991 there was a surge of longer lasting light bulbs. For instance, Edison’s 16-watt light bulb could last 1500 hours meanwhile Philips Company new fluorescent bulb could last up to 60,000 hours. Shuji Nakamura-->In 1995, he created a new type of lighting using blue and white LED, or light-emitting diodes. This action sparked a LED lighting revolution. What types of light bulbs are there? The Incandescent light bulb Halogen light bulb Fluorescent Light bulb LED Light bulb Fluorescent This kind of light bulb creates a flat, cold light, often described as bluish and harsh. It does create the natural daylight effect similar to the halogen bulb, however it cannot be put on a dimmer. The many types of fluorescent light bulbs are the warm ones, the cool ones and special-colored ones. These types usually produce more light and last longer than incandescent bulbs. Excellent to light large areas such as basements and attics. LED light-emitting diode. This kind of light is long lasting and extremely energy efficient. These kind of bulbs only provide directional light, not diffused light, meaning that their light is focused only in one direction and doesn’t spread around its setting compared to the other types of bulbs. These bulbs are pricier than compact fluorescent light bulbs, ranging in cost from about five to six times more than compact fluorescent bulbs.
