Lighting or illumination is the deliberate use of sunshine to attain a practical or aesthetic effect. Lighting contains the usage of each artificial gentle sources like lamps and lighting fixtures, as well as natural illumination by capturing daylight. Daylighting (using home windows, skylights, or gentle cabinets) is usually used as the main source of sunshine throughout daytime in buildings. This could save power in place of using artificial lighting, which represents a major element of power consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have constructive psychological effects on occupants.
Indoor lighting is often achieved using lighting fixtures, and is a key a part of interior design. Lighting can also be an intrinsic element of landscape projects.
With the discovery of fireside, 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 oil lamps to illuminate surroundings. These lamps were comprised of naturally occurring materials such as rocks, shells, horns and stones, were full of grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. A whole bunch of these lamps (hollow worked stones) have been found in the Lascaux caves in fashionable-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
