Interior lighting refers to the use of artificial light sources within a building to enhance visibility and create a desired atmosphere. It includes various types of fixtures such as ceiling lights, table lamps, and wall sconces, which can be strategically placed to illuminate different areas. Proper interior lighting can improve functionality and aesthetics in spaces like homes, offices, and retail environments. The design of interior lighting involves considering factors such as brightness, color temperature, and energy efficiency. Techniques like layered lighting combine ambient, task, and accent lighting to achieve a balanced effect. Effective interior lighting not only enhances the appearance of a room but also contributes to the overall comfort and well-being of its occupants.
