Led Light Research Paper

The first pro that should be addressed is that the incandescent light bulb helped people to be able to do activities that they wouldn’t be able to do unless it was during the morning light. For example, for the rich people during that time, they were able to read, scrapbook and enjoy an evening without it having to be during the morning or afternoon ("The Impact of Light Bulbs on Society.”, Kalinowski). For the working class, the incandescent light bulb was both a con and a pro; the con was that they had to work for longer hours into the night because it wasn’t as dark and they could see everything more clearly. Yet it was also a pro as well because when they were able to see everything more clearly, it prevented them form losing limbs and occasionally their lives. Additionally, they could have more leisure time since they could spend a longer time during the night to do leisure activities ("THE MIDDLE CLASS IN THE LATE 19TH CENTURY.”, Lambert). Another pro that the incandescent light bulb led to was the industrial boom that it caused; since the working class could work for longer hours into the night, they were able to produce more products and goods than in previous circumstances, and therefore, the companies were able to sell and earn more ("The Impact of Light Bulbs on Society.”, Kalinowski). The incandescent light bulb also led to other inventions such as the camera, microwave, oven etc. And

Alternate Hypothesis: The new lightbulb claims that it has average life of more than 1000 hours.

The light bulb was first invented by Thomas Edison on December 31, 1879. Before the people were able to have access to a light bulb they revolved around the sun. People woke up and went to work when the sun rose, and they also went home and went to sleep when the sun went down. With the invention of the light bulb people were able to have extended work hours and didn’t have to solely rely on the sun. Today we have been able to put light bulbs in most of the items that we use on a daily basis. People in today’s society rely on a man made light just as much as they rely on the sun. Without a light people would not be able to travel during the night. We would not be able to function in today’s time without a

The light emitting diodes (LEDs) are low energy, lighting devices with a long lifespan and low energy consumption. The LEDs use specialized power

This type of lighting is already appreciated by the environmental crowd due to the fact that they use less electricity for a given amount of brightness emitted, and they last longer than older lighting technology. Another great benefit is that they emit less heat as well. If you're doing a remodel anyway, you may want to consider LED for any new light fixtures and putting LED bulbs in existing lights.

Switching to solar panels will produce 8350 kilowatts per year, with 2 kilowatts per day, comparing to 11,879 kilowatts per year! Canadian citizens can replace standard light bulbs with fluorescent light bulbs. Fluorescent light bulbs use 75 percent less energy and they last 10 times longer! They can produce 17 watts/hour, while emitting much more light than a normal light bulb. (Ballad, T. (n.d.). How Much Do Energy Efficient Bulbs Save? | Home Guides | SF Gate, n.a., (2012.08.23) Top 10 Things You Can Do to Help - Information on Climate Change - Canada's Action on Climate Change.) Another strategy for individuals to help decrease the amount of GHG emissions would be including high-efficiency appliances apart of their lives. With the use of high efficiency appliances, 20 percent energy is being produced. In 2010, 2800 kilowatts were produced in households, and comparing to 20 years ago, 50 kilowatts were saved per year, which is 35 times better. (Appliances | Natural Resources Canada. (n.d) Therefore, Canadian citizens need to do more home at home to decrease the amount of global

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.

LED lighting should reduce energy costs by using at least 75 percent less energy than incandescent lighting. This will save on operating expenses. The maintenance costs

Today Toronto has over 160,000 streetlight fixtures and ~ 20,000 streetlight classified poles with extended dark fiber to Municipalities, Universities, Schools and Hospitals (MUSH) Sector as likely any eventually passing, if not now, every one of them. Our city is starting to replace all with LED bulbs for a variety of good reason despite some concerns.

In the year 2009, there were 39.6 million adults who were 65 years or older. Baby Boomers made up about 12.9% of the population or roughly 1 in every 8 humans. By the year 2030, this number is expected to almost double making 72.9 million adults who are aged 65 years or older making up for an astounding 19% of the world's population. All in all, 5% of the world’s population are in nursing homes. Lighting should be a primary concern to those living in, working in, and designing Nursing Homes.

Tungsten wires are made for light bulb use, but it is very inefficient because it is better at creating extreme heat than producing light.

Can you ever imagine a world without light bulb? Before light bulb was created, the night can only be lit by the moon and stars. People working and traveling after sunset could only use candles or oil lamps, which caused many inconveniences. Without any bright light, moving inside your own house even seemed dangerous. However, things changed after the ambitious inventors brought their bright idea, which was to light the world, to life. The invention and the commercialization of light bulb not only changed the way people live, but also became a technological breakthrough for future energy use in our daily lives.

“Energy efficiency means using less energy to provide the same service.” An example of this is where a LED lightbulb uses less electrical energy than a traditional incandescent lightbulb to produce the same amount of light. The phrase 'energy efficiency' can also be described as any kind of energy-saving measure. (1)

CFL lightbulbs entered the market at an expensive price, yet the consumers continued to purchase them. Knowing the bulbs “paid for themselves,” the tradeoff was worth it. They used 75% less electricity than incandescent bulbs, lasted 10 times longer and emitted 450 pounds fewer greenhouse gasses. In previous years consumers relied on incandescent lights that were reliable and much less expensive than CFLs. CFLs were backed by utility companies that also wanted the product to be a success, which was obvious through their coupons, trade-ins and price promotions. Aside from the many benefits CFLs offered to consumers, market research showed there were misconceptions that caused hesitancy in consumer adoption. The original product had problems such as light flickering and buzzing, needed continual usage to result in energy savings, could not be used with a dimmer, and recycling the bulbs was not convenient as special measures were needed to dispose of the bulb.

In a modern building daylight can provide most of our lighting needs for the vast majority of the working day. It is therefore unnecessary to spend too much time in designing artificial lighting systems.
