Reduce energy consumption and operational costs for the building. Match
the lighting to your individual needs for a better working environment.
Solution choice depends on what requirements you want to meet. Expenditure can also set limits to your choice.What is lighting control?
phrase lighting control describes change and control of the light
output from the luminaire. The parameters which are changed and
- the distribution of lighting
- levels (lighting strength/luminance)
- spectral distribution (lighting colours)
Control can be manual or automatic and can apply to individual luminaires or groups of luminaires.
this chapter we look at control of levels for individual and groups of
luminaires. Individual or groups of luminaires can be dimmed
continually, or in steps, as well as switched completely on/off.
control, as well as automatic are both possible. The most important
thing is to estimate requirements at an early point, to avoid
lighting control system can save up to 70% of your energy costs, if it
uses an electronic ballast (HF). Movement and daylight detector
controls, could give additional savings.
Modular offices in an
office building are occupied only about 50% of the time, on average.
Daylight contributes between 30 - 60% of the light of a work desk,
depending on surroundings. Energy saving is roughly proportional for
light levels with light dimming and fluorescent lights. It is these
facts which factor in a modern lighting control system, see figure.
