Lighting or illumination is the deliberate use of light to attain a sensible or aesthetic effect. Lighting contains the usage of both artificial mild sources like lamps and light fixtures, in addition to natural illumination by capturing daylight. Daylighting (using windows, skylights, or mild shelves) is usually used as the primary source of light throughout daytime in buildings. This can save power in place of using artificial lighting, which represents a major component of power consumption in buildings. Proper lighting can improve process performance, enhance the appearance of an area, or have positive psychological results on occupants.
Indoor lighting is often completed using light fixtures, and is a key part of interior design. Lighting may also be an intrinsic component of landscape projects.
With the invention of fire, the earliest form of artificial lighting used to light up an area were campfires or torches. As early as 400,000 BCE, fireplace was kindled in the caves of Peking Man. Prehistoric people used primitive oil lamps to light up surroundings. These lamps were made out of naturally occurring materials corresponding to rocks, shells, horns and stones, were full of grease, and had a fiber wick. Lamps usually used animal or vegetable fats as fuel. A whole bunch of these lamps (hole labored stones) have been found in the Lascaux caves in modern-day France, courting 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
