Abstract (en)
[origin: CA2781515A1] The invention relates to a light for illuminating a useable area, in particular a merchandise display area (W), comprising an adaptive illumination unit (1) which has a number of coloured light-emitting diodes which emit light in the basic colours of a colour system, a sensor system (2) directed towards the useable area (W) which detects a light spectrum reflected by the useable area (W) and/or objects lying on the useable area, and a control unit (3) which is coupled to the sensor system (2) and is designed to determine at least one dominant colour from the reflected light spectrum detected by the sensor system (2), and to actuate the light-emitting diodes to emphasise the at least one dominant colour such that they emit a light spectrum of a pre-specified colour temperature and/or intensity, in which the portion of the at least one dominant colour is increased.
