Color emphasis and preservation of objects using reflection spectra

摘要

A lighting arrangement (100, 300, 400, 600) configured to illuminate an object (108, 308, 408, 608), the lighting arrangement (100, 300, 400, 600) configured to emit light of a plurality of colors, and a control unit for controlling mixed light emitted by the lighting arrangement is disclosed. The control unit is configured to determine the object (108, 308, 408, 608) to be illuminated and to receive a reflection spectrum of the object. Then, the control unit selects control parameters for mixed light emitted by the lighting arrangement, the mixed light having an illumination spectrum matching the reflection spectrum of the object based on predetermined parameters relating to the type of object. Furthermore, the lighting arrangement illuminates the object based on the selected control parameters provided by the control unit. A corresponding method and a computer program product are also disclosed.

1. A lighting arrangement configured to illuminate an object, the lighting arrangement configured to emit light of a plurality of colors, the lighting arrangement comprising a control unit configured to:
determine the type of object to be illuminated; receive a reflection spectrum of the object; select control parameters for controlling mixed light emitted by the lighting arrangement, the mixed light having an illumination spectrum matching the reflection spectrum of the object based on predetermined parameters relating to the type of object; and control the lighting arrangement for illuminating the object with said illumination spectrum based on the selected control parameters, wherein the lighting arrangement further comprises a detector in communication with the control unit provided for identifying the object, and a database storing a plurality of pre-stored reflection spectra, wherein a pre-stored reflection spectrum of the object is acquired from the database comprising the plurality of pre-stored reflection spectra, and wherein, for a first object type, the illumination spectrum matches a reflection spectrum for the first object type to a lesser degree than the illumination spectrum for a second object type matches a reflection spectrum of the second object type such that the illumination spectrum for the first object type is whiter than the reflection spectrum for the first object type.
