Abstract
Abstract 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.

Illumination system for providing a number of different illumination modes and comprising a plurality of illumination units being adjustable to a number of light output levels, each of said illumination units comprising a programmable controller for adjusting its light output level to a level associated with a selected one of said different illumination modes, the programmable controller being provided with an identification address, characterized in that the system comprises a programming device for transmitting programming signals to the programmable controller of said illumination units for storing in a memory of said controller predetermined light output levels associated with illumination modes.
Claim 2
Dependent Claim
53 words
Illumination system according to Claim 1, characterized in that the programming device comprises means for transmitting to illumination units with a given identification address programming signals for adjusting these units to a predetermined light output level and for storing said predetermined light output level as being associated with one of the illumination modes.
Claim 3
Dependent Claim
66 words
Illumination system according to Claim 1, characterized in that the programming device comprises means for transmitting to all illumination units a programming sequence comprising light output level information and address information for adjusting all illumination units to a predetermined light output level, the programming sequence comprising an additional control signal for storing said predetermined light output levels as being associated with one of the illumination modes.
Claim 4
Dependent Claim
31 words
Illumination system according to preceding Claim 1, 2, or 3, characterized in that the programming device comprises a memory for storing and retaining therein a plurality of sets of illumination modes.
Claim 5
Dependent Claim
143 words
Illumination system according to Claim 1, 2, 3 or 4, characterized in that the controller of the illumination units are arranged to adjust the light output level to one of a plurality of discrete steps, and wherein the programming device is arranged to transmit a programming sequence comprising, in this order, - signals for setting illumination units with a given identification address at maximum or minimum light output level; - a signal for increasing or decreasing with one step the light output level of illumination units with a given identification address which signal is present as many times as the difference in steps between the maximum or minimum light output level and the predetermined light output level; - a signal for activating the programmable controller of each illumination unit to store the present light output level as being associated with an illumination mode.
Claim 6
Dependent Claim
37 words
Illumination system according to any of the preceding Claims, characterized in that the signals from the control device and/or the programming device are transmitted to the illumination units by means of wireless transmission, preferably by infrared transmission.
