Source/Task Geometry: Overhead ambient lighting and under-counter task
lighting will minimize confusing shadows. Locate luminaires so that
shadows are minimized and the light is where it is needed.
Horizontal and Vertical Illuminance: In order to prepare food, read recipes
and communicate with friends and family, adequate lighting levels need to
be provided. Dimming the lighting can not only save energy, but give
flexibility to the occupant.
Target Horizontal Illuminance ( 10%): 300 lux (30 fc)
Traditionally, kitchen lighting has been accomplished with a single overhead luminaire
located in the center of the kitchen. With this arrangement, preparing food at the
counter is a challenge, since the body shadows the work area. Ideally, locate
luminaires above the cabinets so that the kitchen is filled with indirect ambient light.
Then, locate under-cabinet luminaires for localized task lighting. Direct, recessed
lighting is appropriate over the sink area or other areas without overhead cabinets.
