Description of the invention: [Technical field of the invention] The present invention provides a color temperature adjustable method of a colorimeter, especially an accurate chromaticity value of a reachable spectrophotometer, and the price is relatively light. Color meter is a cheap color temperature adjustable method. [Prior Art] Press, the colorimeter is used to measure the color performance value of the object under various appropriate standard lighting conditions. The colorimeter can objectively measure different objects and colors, especially for example: Plastics, paints, coatings, printing and other colored reflective layers, etc., to achieve effective color control and transmission and replication, is an instrument that is important for color measurement regardless of industrial application or academic research. One. In order to quantify and define the color in a scientific way, the International Commission on Illumination CIE established in 1931 the color matching function λ(λ), y(A), 2 (again) for CIE under equal energy, for any object to be illuminated. The presented color 'such as - source spectral intensity SQ) and the object reflectivity are R (A), and the color matching function can be used to calculate the color combined by the XYZ color base. This χγζ color space is collectively referred to as the CIE 1931 color space system. When a set of χγζ values is obtained, if the position in the coordinate space is considered, the color coordinate value must be drawn in the three-dimensional coordinate space. This is inconvenient in analysis and application, so it is normalized according to the brightness. The concept, in dealing with the χγζ color coordinates, can be preceded by the conditional expression of the xy color coordinate: Xf y+ z= i, χ The determined color space is called the CIE Xy chromaticity diagram. 'The existing reflective colorimeter, the method of obtaining the chromaticity value' is based on the standard method of CIE, 5, 1291549, with the reflected light on the object, plus the color function defined by CIE, for different wavelength components. Different weights are considered, and finally the total energy size is calculated 'according to the different color matching function I, to obtain individual color: value. The weighting of the color matching function and the sum of the stimulation energy can be summarized into the following two categories in the design principle: Another, filter-type colorimeter (as shown in the seventh figure), need to cooperate A specific standard light source (2 Q ), such as CIE standard A light source ΠΕ, ΠΕ standard C, or CIE standard D light source D, etc., is irradiated on the surface of the object to be tested (; :), and then receives the reflection to 22 After passing through the -color function filter (2 3 ) inside the colorimeter, the light intensity value of each of the multiple channels is received to obtain the object chromaticity value. However, because the standard light source D currently on the market does not have a color matching function, jb; f 9 Q, and - piece (2 3) is not well plated 'the measured rut is difficult to serve as inaccurate The level of the position. ^Value# 2. Spectral colorimeter (as shown in the eighth figure), : Source (... after illuminating the object to be tested (31), the white light = the spectrometer inside the meter (33) receives the calculated object 3 2 Finely operated by the instrument and set the reflectivity and value of the mountain. The P-and the chromaticity of the object can be measured under various standard light sources. However, the spectral colorimeter can calculate the finer value of the object to be tested. However, since the spectrometer (33) is contained internally, the price is relatively good; = chromaticity "Because the above-mentioned colorimeter has its own shortcomings, therefore, Ben: Bei.
