Lighting provides us with visibility and can create atmosphere and emotion. It is also an important design element in a room. When it comes to interior design, there are three basic types of lighting: ambient, accent, and task lighting. Ambient lighting is used to provide general lighting to an entire room. It is usually produced by overhead fixtures, such as chandeliers, pendants, or recessed downlights. They evenly distribute light in a room and create a basic level of illumination. It is the most commonly used type of lighting, as it provides the most even distribution of light in a room. Accent lighting is meant to draw attention to certain specific elements in a room, such as artwork, plants, or architectural features. It can be done by placing spotlights or sconces on walls, or by using lamps. The light should be focused direct on the feature being highlighted, in order to draw attention to it. Lastly, task lighting is used to light specific areas of the room, usually for activities that require concentration such as reading or cooking. Task lighting is usually a more directional light, such as a lamp or even a track light. It should be bright enough to illuminate the area that it's focused on, without spilling light into other parts of the room. Overall, proper lighting is essential for interior design. It can help make a room more inviting, create atmosphere, and highlight certain features. Therefore, it should be taken into consideration when planning the decor of a room.
