A Standard Formulation Method and Test Method for Color Tolerance of Arbitrary Light Sources

Abstract

The invention belongs to the lighting technical field and relates to a standard setting method and test method of the color tolerance adjustment of an arbitrary light source. The standard setting method of the color tolerance adjustment of an arbitrary light source includes the following steps that: two adjacent standard colors A and B which are larger than and smaller than the color temperature value of a required light source respectively are found in conventional light source color standards according to the color temperature value of the required light source; the standard parameters of the standard colors A and B are found in the conventional light source color standards; and calculation parameters used for formulating the color tolerance adjustment standards of the required light source are selected in a numerical value interval between the standard parameters of the A and B. With the standard setting method of the color tolerance adjustment of the light source satisfying any color temperature requirement is provided, and standards which are set by using the method are beyond conventional standards; the light source can have specifications approximate to required specifications and a color close to a desired color; errors can be reduced; and the color difference of an actual light source and the required light source can be judged more accurately and conveniently.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a standard formulation method and testing method for the color tolerance of any light source. Background technique [0002] LED color tolerance is the difference between the X and Y values ​​of the light, color and electricity detection system and the standard light source. The smaller the value, the higher the accuracy, indicating that the measured light source is closer to the standard light source. Generally, when measuring color tolerance, it is the color comparison under a certain light source, not the deviation under different light sources. The spectrum emitted by the light source is the same as There are differences between the standard spectra, and the standard spectra change with the color temperature. If the same light source has different standard spectra, the color tolerance will be different. The color tolerance unit: SDCM. [0003] According to China's national e...

Problems solved by technology

[0014] If the required color is not equal to any color in Table 1, that is, deviates from the standard color, the color tolerance value is large, and the farther the deviation is, the greater the color tolerance value. That is, the standard color in Table 1 is used to calculate the color of the required color. Tolerance, cannot accurately reflect the difference between the actual light source and the required light source
