The Three Elements of Light

General or Ambient lightingprovides an area with overall illumination. Also known as ambient lighting, general lighting radiates a comfortable level of brightness, enabling one to see and walk about safely.

Task Lighting or Lighting at the Work planehelps you perform specific tasks such as reading, sewing, cooking, homework, hobbies, games, or balancing your checkbook

Light or Highlightingadds drama to a room by creating visual interest. As part of a decorating scheme, it is used to spotlight paintings, houseplants, sculpture, and other prized possessions, or to highlight the texture of a wall, drapery or outdoor landscaping.

Richard Kelly

Focal Glow or Task light is…“the campfire of all time, the glowing embers around which stories are told”“the light burning at the window or welcoming gleam of the open door”“directive, creates a brighter center: tells us what to look at, organizes, marks the important element”

Sparkle or Glitter is…“a play of brilliants”“the sensation of a cache of diamonds in an opened cave”“a ballroom of crystal chandeliers”

Subjective Impressions

• Professor John Flynn’s studies in the 1970’s established fundamental research about how the distribution of light and resulting patterns of light effect our subjective impressionssubjective impressions of a place.

• In particular patterns of light on vertical surfaces, because they are more noticeable, strongly influence our impressions of:

Spaciousness / Confinement

Visual Clarity / Haziness

Relaxation / Activation

Private/ Public

1. Rule of Thumb: Mounting Distance = Spacing Distance

2. Rule of Thumb: Mounting Distance = 1/3 the Ceiling height

1. Mount the wall wash fixtures 2 to 3 feet from the wall on ceilings up to 9 feet high.

2. Mount the wall wash fixtures 3 to 4 feet from the wall on ceilings up to 9 feet and 11 feet high.

3. Follow Manufactures Recommendations!

What Makes A Good Wall for Grazing

31

Lighting a Vertical Surface: Wall GrazingWall GrazingFor dramatic shadows on textured surfaces (such as draperies, stone, or brick) mount the fixtures 6 to 12 inches from the wall, with the fixtures the same distance apart and aimed downward for a grazing effect.

Accent Lighting

Accent Lighting

Generally Rule of Thumb

• fixtures should be aimed at a 30 degree angle from the vertical tothe vertical to prevent light from shining in anyone's eyes and to avoid disturbing reflections on the surface of the object.

Accent Lighting

Generally Rule of Thumb

• Usually, one fixture is required for each object being accented, but two can provide soften shadows and provide a wider wash of light
