The Light Bulb A Luminous Invention - 1341 Words

Light bulbs are an invention that transformed the modern world to what we know it to be today. It was first created by Thomas Edison after countless hours of trial and error. He finally found a combination that worked and lasted for twelve hundred hours. It relied on a bamboo filament and was more efficient after Edison was able to remove more oxygen from the bulb. There are now four main types of light bulbs: incandescent, halogens, fluorescent, and LEDs. Although performing one basic task they all have advantages and disadvantages. Incandescent light bulbs are the oldest and most common type of light bulb. Incandescent bulbs have filament made of Tungsten. Tungsten was chosen to be the filament because it can be made very thin, put under high resistance and has a high melting point. This allows electrons to return to lower energy states and it releases photons that are visible to the human eye. Inside of the light bulb, manufactures have to fill bulb with a combination of nitrogen and argon because they are less reactive than oxygen we breathe (Uva, 2011, p. 1). The light bulb actually works due to electrical current being passed through the filament. The electrons of the filament become excited which causes the filament to get hot and glow creating the light. When the tungsten is heated it sublimates which caused incandescent light bulbs to get darker over time. After being used for a certain amount of time, the tungsten wire becomes thin and breaks. This causes theShow MoreRelatedNick Holonyak And The Invention Of Light Diode ( Led )1384 Words   |  6 PagesNick Holonyak and the Invention of Light Emitting Diode (LED) Introduction Nick Holonyak was born in the United States of America in Zeigler, Illinois on the third of November in 1928.

This variety of pollution is called light pollution or photo pollution. The effects of light pollution on humans and the world’s various ecosystems are various and need to be realized. Since their initial creation, light bulbs have continuously grown in number and type. Streets are now lined with bright yellow fluorescent, runways are now mapped out with multi-colored bulbs, etc. The utilization of light bulbs has expanded to whereRead MoreEssay about Compact Flourescent Lamp and the Environment3703 Words   |  15 PagesCompact Flourescent Lamp and the Environment Abstract Technological advances have come a long way since the incandescent light bulb. Today, the compact fluorescent lamp (CFL) is the most energy efficient light bulb on the market. In the beginning, consumers had resistance toward the CFL. With governmental support in establishing energy-efficient lighting programs, the CFL have been able to stay in the market and improve throughout the years.
