Abstract
According to an aspect of the present inventive concept, this and other objects are achieved by a lighting system () for illuminating an article () comprising: a lighting device () arranged to emit light () towards the article (), wherein a spectrum of the emitted light () is controllable. The lighting system () further comprises a controller () configured to control the lighting device () responsive to detection of presence or movement of an object () within a detection zone () associated with the article (). The controller () is configured to: control the lighting device () to emit light () having a first spectrum in response to absence of an object () or movement of an object () within the detection zone (), and control the lighting device () to emit light having a second spectrum in response to presence of an object () or movement of an object () within the detection zone (). 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 ().
