Illumination system, illumination method and lighting controller

Abstract

The invention relates to an illumination system comprising a luminaire which is configured to provide light according to a plurality of preset combinations of illumination level and color temperature, controlled via a control protocol. The system further comprises a user interface comprising means to (manually) select the illumination level and color temperature from said plurality of preset combinations. The number of preset combinations is at least three. The control protocol comprises transition times for transitions between said preset combinations, said transition times being in the range of about 2 seconds to about 5 minutes. The invention further relates to an illumination method using the illumination system and to a controller uploaded with said preset lighting settings. The use of the system in dependence on the activity, time of day or atmosphere in the classroom has been proven to improve the learning behavior of children. It therefore is a learning tool for teachers.

The invention claimed is:  
     
       1. An illumination system comprising:
 at least one luminaire which is configured to provide light according to a plurality of at least three preset combinations of illumination level and color temperature, wherein the color temperature and the illumination level are controlled via a control protocol; and 
 a user interface configured to select the illumination level and color temperature from said plurality of preset combinations, the control protocol comprising transition times for transitions between said preset combinations, said transition times being in the range of about 2 seconds to about 5 minutes,
 wherein at least one combination of said plurality of preset combinations is a calm setting in which the illumination level is at least 100 lux and the color temperature is about 2900K, or a standard setting in which the illumination level is at least 100 lux and the color temperature is about 3500K, and at least one other combination of said plurality of preset combinations includes at least one of an energy setting in which the illumination level is about 650 lux and the color temperature is at least 9000 K or a focus setting in which the illumination level is at least about 750 lux and the color temperature is about 6500K, 
 wherein the plurality of preset combinations comprises at least four preset combinations, and the illumination system further comprises a lighting controller comprising a motion detector which is configured to automatically switch-over the illumination system to the calm setting upon detection of a level of motion that supersedes a preset motion threshold value. 
 
 
     
     
       2. An illumination system as claimed in  claim 1 , wherein the transition times are in the range of about 3 seconds to about 10 seconds. 
     
     
       3. An illumination system as claimed in  claim 1 , wherein the illumination level in each preset combination is at least 300 lux. 
     
     
       4. An illumination system as claimed in  claim 1 , wherein in the plurality of preset combinations is comprised a preset presentation combination in which the illumination is spot focused and in which the illumination level is less than 100 lux and the color temperature is less than 3000K. 
     
     
       5. An illumination system as claimed in  claim 1 , further comprising a lighting controller configured to detect motion and/or non-modulated light. 
     
     
       6. An illumination system as claimed in  claim 1 , wherein the control protocol is selected from the group of standard protocols DALI, ZIGBEE and DMX. 
     
     
       7. An illumination system as claimed in  claim 1 , further comprising least one additional motion detector. 
     
     
       8. An illumination system as claimed in  claim 1 , wherein the illumination system simultaneously provides at least two preset combinations of said plurality of preset combinations, such that for each activity space in one room there is a respective, independently controlled preset combination of said at least two preset combinations.
