Lighting is a critical factor in the design of any interior environment. Lighting can sculpt and shape a space as well as create a particular ambiance and mood. It affects the usability of a space by influencing visibility, accentuating key features, and creating focal points. Lighting should also be considered from an energy savings perspective, as the most effective lighting should require minimal energy input. Great lighting design means thoughtfully selecting and controlling your lighting throughout a space. Radiant lighting provides general illumination and should be used to fully expose any given space. Accent lighting highlights architectural details and other objects such as artwork. Task lighting is necessary for specific activities like reading or cooking. Additionally, reflective surfaces be used to reflect and diffuse light into a space, making it more inviting and cheerful. At the same time, contemporary technologies like LED lighting have enabled designers to be more imaginative when planning a lighting design. LED lighting is more energy-efficient, can be precisely controlled, and offer highly efficient levels of illumination. Today, LED lights are used for everything from aesthetic purposes to safety and security applications. No matter what the design of the space, lighting can be used to transform it. Accentuating features with the right light can create a sense of drama and energy. Lighting can also be used to create a sense of relaxation, tranquility, and intimacy. By creating the right atmosphere and mood through lighting, designers can truly bring a space to life.
