Lighting - History

History

With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 BCE, fire was kindled in the caves of Peking Man. Prehistoric people used primitive lamps to illuminate surroundings. These lamps were made from naturally occurring materials such as rocks, shells, horns and stones, were filled with grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. Hundreds of these lamps (hollow worked stones) have been found in the Lascaux caves in modern day France, dating to about 15,000 years ago. Oily animals (birds and fish) were also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps were also invented. Chandeliers were an early form of "light fixture". With the development of electricity and the incandescent light bulb, the luminosity of artificial lighting improved to be able to used indoors. They became widely used and extended the time that people could stay up, among other developments.

Famous quotes containing the word history:

    This above all makes history useful and desirable: it unfolds before our eyes a glorious record of exemplary actions.
    Titus Livius (Livy)

    What has history to do with me? Mine is the first and only world! I want to report how I find the world. What others have told me about the world is a very small and incidental part of my experience. I have to judge the world, to measure things.
    Ludwig Wittgenstein (1889–1951)
