DEVICE AND METHOD FOR DYNAMIC LOAD CONTROL IN LIGHTING SYSTEMS

摘要

Present invention provides controlling power consumption of at least one group of plurality of groups of lighting devices, each group comprising change range indicating values, by which energy consumption of the respective group can be changed. To this, for each of the at least one group a corresponding target power consumption change value is determined, by which power consumption of the corresponding group has to be changed, by selecting for each group of the plurality of groups a corresponding target power consumption change value from the corresponding change range of the corresponding group such that normalized illumination change values of the plurality of groups have minimal difference among each other, each of the normalized illumination change values being determined for corresponding group by use of the selected target power consumption change value of the group.
