Lighting plays a big part in how we perceive spaces and the objects within them. A designer can use lighting in a myriad of creative ways to define a user's understanding of the functions of a space and to place emphasis on the objects within them. For instance, task lights can direct you to where to read in the case of a library or a preparation work-top in the case of a kitchen island.
Architectural lighting is employed to framing a space, creating a sense of movement within it and defining different moods or zones. The hue and temperature of light in combination with the furniture and finishes can be used to convey emotions or feelings such as peace, comfort and homeliness. In this regard, harsh white lights may not be suitable for a family lounge, similarly, a commercial space such as a supermarket, should not employ colored, moody lighting like what is used in a lounge or bar.
In designing the lighting for spaces, a designer must always think of the intended mood to be created, how user(s) should perceive the space and its functions and how the lighting scheme fits with the type of space. The importance of proper lighting design cannot be overemphasized as it can undermine the purpose and intended use of a space and the experience meant for users to have, hence, it must be intentionally planned, designed and woven into the fabric of the space.
