Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting consists of the usage of both synthetic gentle sources like lamps and lighting fixtures, in addition to natural illumination by capturing daylight. Daylighting (using home windows, skylights, or gentle cabinets) is sometimes used as the primary supply of light throughout daytime in buildings. This will save energy rather than using synthetic lighting, which represents a major element of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an space, or have positive psychological effects on occupants.
Indoor lighting is usually achieved using lighting fixtures, and is a key a part of interior design. Lighting will also be an intrinsic element of landscape projects.
With the invention of fireside, the earliest type of synthetic lighting used to light up an space have been campfires or torches. As early as four hundred,000 BCE, fireplace was kindled in the caves of Peking Man. Prehistoric individuals used primitive oil lamps to light up surroundings. These lamps have been comprised of naturally occurring supplies such as rocks, shells, horns and stones, have been filled with grease, and had a fiber wick. Lamps sometimes used animal or vegetable fat as fuel. Tons of of those lamps (hollow worked stones) have been found in the Lascaux caves in fashionable-day France, relationship to about 15,000 years ago. Oily animals (birds and fish) have been also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps have been also invented
