When the primary emphasis of lighted space is within the visual field, the resulting patterns of brightness reinforce our priorities for defi ning space and defining activities. People define their environment through a process of additive perception. Information is gathered by scanning the boundaries of a space, thereby forming a concept of direction and limits. When the lighting system is designed to establish the physical boundaries of a space, it helps people to maintain a sense of direction and an understanding of spatial form with minimal distraction from the environment.
Lighting helps to defi ne and separate the major surfaces of a space if the shape of the light distribution relates to the form of the surface. For example, a wall or ceiling lighted with a uniform wash of light will approximate the form and dimension of that surface. A linear wash of light facilitates clear visual separation between the vertical planes (wall surfaces) and the horizontal planes (ceiling and floor surfaces), the borders of interior space. The evenly lighted wall is perceived as an integrated visual form (see Color Plate 38). The same is true of the evenly lighted ceiling plane.
Four Lights Lighting Vertical Surfaces
Vertical surfaces require special attention: they are the fi rst surfaces that we see upon entering a space. Vertical surfaces define the boundaries of the space; they are used for displaying works of art and communicating a message. Clear perception of vertical surfaces signifi cantly impacts our perception of the overall design.
Reliance on formulas to provide a specific illuminance value on the horizontal plane disregards the importance of vertical surfaces. Consequently, luminaires used for ambient illumination often cast unanticipated or undesired light patterns on the vertical surfaces, or leave them in relative darkness. The resulting environment, if not distracting, is unintentionally dull and monotonous. It is critical to anticipate where downlight distributions.
