Indoor lighting refers to the various types of artificial light sources used within buildings to illuminate spaces. Common sources include light bulbs, LEDs, and fluorescent lights. These lighting options can enhance visibility, create ambiance, and improve safety in homes, offices, and public areas. Different lighting techniques, such as ambient, task, and accent lighting, serve specific purposes. Ambient lighting provides overall illumination, while task lighting focuses on areas where activities like reading or cooking occur. Accent lighting highlights particular features, such as artwork or architectural details, adding depth and interest to indoor environments.
