| The three components of light
Nature combines the soft, scattered light from the sky
with the vibrant, focused light from the sun. In the
sophisticated working world this finds it parallel in the
ambient light that provides the basic brightness in a
room, and zone lighting which focuses on selected
areas. Both components are essential for lighting that
is not merely functional but which also enhances
well-being and mood. Mood lighting complements
ambient and zone lighting. Rather than actually
illuminating, mood lighting is like a fire, working as
a light feature in itself to create an exceptional
atmosphere. |

| 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 ceiling or wall, on window sill, sideboard or chest of drawers, shelf or floor. |
