Reflector, layered lighting system Flashcards
probably the most important elements in the construction of luminaires for controlling light.
reflectors
a type of luminaire that is direct light predominantly downwards
Downlights
combine a downlight and an up light in one fixture. These luminaires are applied for the simultaneous lighting of floor and ceiling or for grazing lighting over a wall surface
up-downlights
a system where light sources are shielded by a panel parallel to the wall and attached to the ceiling to distribute light downwards over the wall.
Cornice lighting
a system where light sources are shielded by a ledge to distribute light upwards over the ceiling and upper wall. It is a form of indirect lighting
Cove lighting
a system where light sources are shielded by a panel parallel to the wall usually across the top of a window. This provides light both upwards and downwards over the wall.
