Lighting is an important part of any room, as it can vary the atmosphere and add certain levels of drama to the area in question. It not only aids visibility but adds a feeling of warmth and coziness. There are several types of lighting, generally classified as ambient, task, accent, decorative and natural, and each category differs according to its purpose. Ambient lighting provides a general level of illumination throughout the room. This type of lighting is functional and allows us to see and move around safely, though it is not overly decorative. Task lighting helps us to focus on specific tasks such as reading or writing. This type of light usually directs beams in specific directions for targeted lighting. Accent lighting provides more drama to the room and is used to focus attention on particular points of interest. This could be a work of art or a certain section of a room, such as an alcove. It shines a concentrated beam of light onto a surface to highlight its form and texture. Decorative lighting can be further broken down into two categories; lighting for illuminating the space and lighting with a purely decorative purpose, such as a candelabra or tiffany lamp. Finally, natural lighting is the light which comes from natural sources, such as the sun or moon. It differs in character according to its source and varies in intensity throughout the day. Natural lighting is important for our overall well-being as sunlight is essential for vitamin D production. In conclusion, lighting plays an important role in creating atmosphere, visibility, safety, and health. Without lighting, our lives would be much less pleasant than they currently are.
