<p>Illumination system for providing a number of different illumination modes and comprising a plurality of programmable illumination units. A space is illuminated by a plurality of illumination units, each of which can be set at various light output levels. Different tasks, for example reading/writing, meeting or wording with a VDU, are to be performed in the space and each one may require a different illumination mode, i.e. the setting of the light output levels of the units. Each unit is provided with a programmable controller having stored in it a table associating a light output level for each illumination mode. Initialization and restoration of the tables in the programmable controllers is performed by a special programming device. The programming device emits sequences of signals for changing the light output levels and storing them as belonging to one of the illumination modes. The programming device may contain a memory in which a number of sets of illumination modes, for different spaces and persons, can be stored. <IMAGE></p> |
