Artificial lighting refers to the use of man-made sources of light to illuminate spaces. This can include various types of light bulbs, such as incandescent, fluorescent, and LED. Artificial lighting is essential for visibility in homes, offices, and public areas, especially during nighttime or in places without natural light. The primary purpose of artificial lighting is to enhance safety and productivity. It allows people to perform tasks, socialize, and navigate spaces after dark. Additionally, artificial lighting can influence mood and ambiance, making it an important aspect of interior design and architecture, often integrated with smart lighting technology for added convenience.
