3 Changing colour temperatures
So that people feel good and objects are shown to full effect
Taking nature as a model. Nature has shown us how light influences
our mood by colour, intensity and direction. Even subtle changes in
white tones suffi ce to provide stimulation or relaxation. This biological
effect of light and the associated possibility of stabilising and syn-
chronising the human body clock is now being factored into design
concepts more and more. Light is therefore more than just a pre-
condition for seeing properly; light is becoming a health factor,
especially in situations where people are looking to rest and relax.
This also applies in all areas where success depends on perfor-
mance. Effective use of daylight is at the heart of biologically effec-
tive lighting concepts. If such light is not available naturally, intelli-
gently controlled artificial lighting takes over as many of its tasks as
possible. Predefined timelines stabilise people’s inner body clock by
creating the right light colour and appropriate lighting levels at all
times of the day.
In the case of product display, there are further reasons for ad-
justing white tones. The right colour temperature at the right time
cleverly presents the goods on offer in shops and retail areas to full
effect. In galleries and museums, finely tuned colour temperatures
and luminance levels enhance the perceived quality of works of art.
The range of luminaires and lighting control technologies featuring
variable colour temperatures provided by Zumtobel include a variety
of white tone options in the case of Selectable White, Balanced
White solutions for mixing warm and cool white light sources as
required, through to Tunable White, which allows to continuously
change the colour temperature along the Planckian curve.
8:00 Warm white light for wallwashers and corridors gets the day
off to an agreeable start
10:30 Artificial lighting is turned down as more daylight becomes
available and the light colour is made more intermediate
