摘要： According to an aspect of the present inventive concept, this and other objects are achieved by a lighting system (100) for illuminating an article (112) comprising: a lighting device (102) arranged to emit light (103) towards the article (112), wherein a spectrum of the emitted light (103) is controllable. The lighting system (100) further comprises a controller (104) configured to control the lighting device (102) responsive to detection of presence or movement of an object (110) within a detection zone (108) associated with the article (112). The controller (104) is configured to: control the lighting device (102) to emit light (103) having a first spectrum in response to absence of an object (110) or movement of an object (110) within the detection zone (108), and control the lighting device (102) to emit light having a second spectrum in response to presence of an object (110) or movement of an object (110) within the detection zone (108). The light having the first spectrum presents, in at least one wavelength interval, a lower power than the light having the second spectrum. Moreover the light having the first spectrum and the light having the second spectrum provide a corresponding level of illumination of the article (112).

摘要： A lighting device comprising a housing with a light emission window and, opposite thereto, a reflector. A planar light transmissive carrier arranged in between the light emission window and the reflector and comprising, at least on a side facing towards the reflector, a grid of a plurality of light sources. The plurality of light sources comprise a first group of first light sources and a second group of second light sources. Each first light source has a respective first emission orientation in a respective first direction away from the reflector and each second light source has a respective second emission orientation to issue light towards the reflector, which light, after reflection, is redirected into a respective first direction. The lighting device is able to provide accent lighting and/or diffuse lighting issued by light sources arranged on one planar carrier.

摘要： 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.
