Abstract: A standard light source color matching observation box comprises a box body, the interior space of which forms an observation chamber. The top of the observation chamber is provided with a standard light source comprising a halogen tungsten lamp under which a light filter is provided. The top of the observation chamber is further provided with an LED light. The halogen tungsten lamp emits a light ray through the light filter to be mixed with the light ray of the LED light. The illumination energy provided by a narrow-wave LED light source occupies 20% or less of the total radiation energy. The quality of the compensated light source of the invention is lower than <0.2 A level according to the metamerism index specified by D illuminant of the CIE standard. An object to be measured undergoes a color measurement by the compensated light ray to ensure accuracy of long-time color measurement.
Abstract: The present invention discloses a method for performing color measurement using a standard light source color matching observation box. The method comprises: arranging a halogen tungsten lamp and a light filter in the color matching observation box for cooperation, wherein the light ray of the halogen tungsten lamp emits a main body radiation light ray through the light filter; arranging a plurality of narrow-wave LED light sources of different light-emitting wavelengths to emit a compensation light ray; mixing the main body radiation light ray and the compensation light ray in the color matching observation box into a mixed light ray that uniformly simulates a standard D illuminant; and performing a color measurement on a measured object in the color matching observation box by the mixed light ray.
