Artificial lighting refers to the use of man-made sources of light to illuminate spaces, especially when natural light is insufficient. Common examples include light bulbs, LEDs, and fluorescent lamps. These sources help us see in the dark, enhance our mood, and create a comfortable environment in homes, offices, and public places. The invention of artificial lighting has transformed daily life, allowing activities to continue after sunset. It plays a crucial role in various settings, from streetlights guiding drivers at night to task lighting that helps people read or work efficiently. Overall, artificial lighting is essential for modern living.
