Lighting or illumination is the deliberate use of sunshine to attain a practical or aesthetic effect.

Daylighting (utilizing home windows, skylights, or gentle shelves) is sometimes used as the principle supply of sunshine during daytime in buildings. This may save energy rather than utilizing synthetic lighting, which represents a significant part of energy consumption in buildings. Proper lighting can enhance job efficiency, improve the looks of an space, or have constructive psychological effects on occupants.
Indoor lighting is often accomplished utilizing lighting fixtures, and is a key part of interior design. Lighting can be an intrinsic part of landscape projects.
With the invention of fireside, the earliest form of synthetic lighting used to illuminate an space had been 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 had been constructed from naturally occurring supplies corresponding to rocks, shells, horns and stones, had been stuffed with grease, and had a fiber wick. Lamps sometimes used animal or vegetable fat as fuel. A whole lot of those lamps (hole worked stones) have been discovered in the Lascaux caves in trendy-day France, courting to about 15,000 years ago. Oily animals (birds and fish) had been also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps had been also invented
