Abstract: A lighting device comprising a light source being configured to generate source light of a white light emission spectrum having a color correlated temperature (CCT) in a range of 2500-20000K and comprising a control unit being configured to control a lighting element for tuning of the source light with respect to a ratio between a first emission peak in a wavelength range of 460-490 nm and a second emission peak in a wavelength range of 430-460 nm. Thus a lighting device with a tunable/adjustable spectrum is provided that can switch between a first operation state of energy efficiency lighting with a blue peak in the second wavelength range of 430-460 nm, but with blue hazard risk, and a second operation state of less efficient but safe, healthy lighting with a biological stimulant having a blue peak in the first wavelength range of 460-490 nm.

Abstract: A lighting system has a controller which receives input information from physiological sensors associated with users in the area illuminated by the lighting system. Anxiety is detected of a user or users when in or approaching a particular region of the area, and the lighting is changed to reduce the anxiety. In this way, lighting changes only need to be made when there is a need based on the response of the particular users. The system thus 5 enables energy savings as well as more stable lighting conditions.

Abstract: A lighting system controller comprises a controller for controlling an arrangement of lighting units for implementing different lighting effects. A sensor is used to identify a visitor and also to count the number of visits of the visitor which have taken place, for example while the same lighting effect has been in place. A change in the lighting effect is made based on the number of visits of one or more visitors, again for example with the same lighting effect. In this way, the lighting effect is changed automatically when it needs to be changed in order to maintain the interest of visitors (either individually or as a collective group).

Abstract: A lighting system comprises a light source having an exit window and an electrically controllable light processing arrangement, in the form of a grid of cells lying in a plane parallel to the exit window. Each cell has a cell wall formed as electrically switchable element which is switchable between at least two processing modes. The cell wall surrounds an opening, such that light emitted in a normal direction from the light source exit window is not processed, and light passing at an angle to the normal direction greater than a threshold angle is processed by the cell wall for color and/or intensity control.
