Lighting or illumination is the deliberate use of sunshine to realize a sensible or aesthetic effect. Lighting includes the usage of each synthetic light sources like lamps and light fixtures, in addition to pure illumination by capturing daylight. Daylighting (using home windows, skylights, or light cabinets) is typically used as the principle supply of sunshine during daytime in buildings. This could save power rather than using synthetic lighting, which represents a significant element of power consumption in buildings. Proper lighting can improve process efficiency, improve the looks of an area, or have constructive psychological effects on occupants.
Indoor lighting is often achieved using light fixtures, and is a key part of interior design. Lighting can be an intrinsic element of landscape projects.
With the discovery of fire, the earliest type of synthetic lighting used to light up an area have been campfires or torches. As early as four hundred,000 BCE, fireplace was kindled within the caves of Peking Man. Prehistoric people 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 usually used animal or vegetable fats as fuel. Tons of of those lamps (hollow worked stones) have been discovered within the Lascaux caves in fashionable-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
