Lighting or illumination is the deliberate use of sunshine to achieve a practical or aesthetic effect. Lighting contains the usage of both artificial light sources like lamps and light fixtures, in addition to natural illumination by capturing daylight. Daylighting (using home windows, skylights, or light cabinets) is usually used as the primary source of sunshine throughout daytime in buildings. This will save energy instead of using artificial lighting, which represents a major element of energy consumption in buildings. Proper lighting can enhance task efficiency, enhance the appearance of an space, or have positive psychological effects on occupants.

Indoor lighting is often accomplished using light fixtures, and is a key part of interior design. Lighting may also be an intrinsic element of panorama projects.

As early as four hundred,000 BCE, fire was kindled within the caves of Peking Man. Prehistoric people used primitive oil lamps to illuminate surroundings. These lamps have been constituted of naturally occurring supplies similar to rocks, shells, horns and stones, have been filled with grease, and had a fiber wick. Lamps usually used animal or vegetable fats as fuel. A whole lot of these lamps (hollow labored stones) have been found within the Lascaux caves in trendy-day France, dating 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
