Ambient lighting
Ambient light spreads evenly
through space, illuminating an entire
room. It is usually produced by
light that is directed upwards
towards the ceiling, or by luminaires
that emit light evenly on all sides.
It provides the fundamental
brightness which the eye needs for
orientation. It evens out sharp
differences in brightness in a
room, making it easier for the eye
to adapt to different zones. The
eye tires less rapidly as a result.
The eye perceives a complete
absence of ambient lighting, as in
a study with just a single reading
lamp on the desk for example, as
unpleasant. Balanced ambient
lighting on the other hand creates
a comfortable atmosphere that
enhances the sense of well-being.
Zone lighting
Zone lighting delivers a lot of light
where it is needed for specific
activities, e.g. reading, working or
discussion. At the same time it
highlights focal points that are as
important for the harmony of a
room as uniform ambient lighting.
Zone light is produced by luminaires
that direct their light down or
against the wall. The more flexible
the adjustment of the luminaire,
the better it can direct the light
where it is most needed. Where a
conference table is lit by ambient
light alone, the resulting mood will
be like that found in an industrial
kitchen. Zoned lighting on the
other hand accentuates the private
atmosphere of discussion and
debate.
Mood lighting
Mood lighting creates an exceptional
atmosphere. It shines but seldom
illuminates. Instead it stands for
friendliness, fascination and passion.
Its sole purpose: to caress the heart
and soul. Mood lighting produces
its best effects in the evening when
the surroundings are dark. Mood
lighting must not be too bright,
or the mood is soon lost. A mood
light should therefore glow rather
than shine. Mood lighting is
appropriate wherever it can best
deploy its effects, e.g. on a ceiling
or wall, on window sills,
sideboards or chest of drawers,
shelves or floors.
