artificial light

Artificial light refers to illumination produced by human-made sources such as bulbs, LEDs, and fluorescent lamps, rather than natural sunlight. These lights convert electrical energy into visible light, allowing us to see and perform activities in darkness or low-light conditions. They are widely used indoors and outdoors for various purposes, including residential, commercial, and street lighting. Artificial light can be designed to emit different colors and intensities, and advancements continue to improve energy efficiency and visual comfort. It plays a crucial role in modern life, extending our ability to work, relax, and navigate safely after sunset.
