Lighting is an important factor in interior design and one which, when done well, can set the atmosphere of a room and transform a space. It adds an extra layer of impact to any design scheme and can drastically improve the overall look and feel of a room. With advances in technology, lighting can also increase energy efficiency, with LED lights using far less energy than incandescent or fluorescent bulbs. An important aspect of lighting design is understanding the different types of lighting and how they are used. Accent lighting is used to create drama by highlighting key features such as artwork, accent colours or architectural features. Ambient lighting is more general and is used to provide even and comfortable illumination throughout the room. Task lights are directed and tailored to provide focused light on specific areas. These could be in the form of track lighting, pendants or adjustable spots. Finally, decorative lighting spans the chandeliers, wall sconces or floor lamps. Good lighting design is about combining different types of lighting to create the desired effect and atmosphere. General ambient lighting should be your starting point as it allows other core elements such as artwork and furniture to take centre stage. Then you can add task and accent lighting to provide illumination on specific items. Lastly, consider how to add decorative lighting to your scheme to make an impact. In conclusion, lighting design is an important factor in interior design, and the right combination of types of lighting can drastically alter the look and feel of a room. From creating drama with accent lighting to setting the atmosphere with decorative lighting, a well-thought-out lighting scheme can transform any interior.
