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.

Abstract: An illumination device (100) for illuminating an at least partially reflective surface (S) viewable by an observer (O) is disclosed. The illumination device (100) comprises a light-emitting module (110, 120) adapted to generate polarized light having a selected direction of polarization. Further, the illumination device (100) is adapted to illuminate the at least partially reflective surface (S) with the polarized light, and is adjustable so as to effect adjustment in the direction of polarization of light illuminating the at least partially reflective surface (S) in relation to the orientation of a plane of incidence of light incident on the at least partially reflective surface. An indicator (130) is arranged such as to provide guidance for the observer (O) how to adjust the direction of polarization of light illuminating the at least partially reflective surface (S). Thereby, the extent of light reflection from the at least partially reflective surface (S) may be adjusted. A luminaire comprising such an illumination device (100) and a method for facilitating for the observer to adjust the extent of light reflection from the at least partially reflective surface (S) is also disclosed.

Abstract: A lighting device comprising a first light source issuing a first beam and a second light source issuing a second beam. Said first and said second light source are dimmable and together issue light with a total light flux. At a mutually equal light flux of the first and the second beam, the glare level of the second beam is lower than the glare level of the first beam. The lighting device further comprises at least one (programmed) controller which, during operation, moderates said dim levels such that in at least a range of the illumination level a ratio of the dim level of the second beam to the dim level of the first beam increases in a gradual manner with increasing total light flux.
