Information

The disparity between the computer-calculated formula and the goal standard.
The gap between the formula calculated by the computer and the goal standard is referred to as color tolerance. It is computed using a single light source. The lower the figure, the greater the accuracy. It should be emphasized, however, that it only provides color comparisons under a single light source and cannot identify deviations under diverse light sources. The discrepancy between a light source's spectrum and the standard spectrum.


Explain
The gap between the formula calculated by the computer and the goal standard is referred to as color tolerance. It is computed using a single light source. The lower the figure, the greater the accuracy. It should be emphasized, however, that it only provides color comparisons under a single light source and cannot identify deviations under diverse light sources. The discrepancy between a light source's spectrum and the standard spectrum.


Illustrate
The standard spectrum shifts depending on the color temperature. The color tolerance of the same light source varies depending on the standard spectrum. The universal photochromic analysis system, on the other hand, will automatically detect the color temperature range of the measured light source to calculate the color temperature of the standard spectrum when measuring. Color tolerance is measured in SDCM, and the color tolerance needed for common energy-saving bulbs should be less than 5SDCM.


Definition
The color tolerance is defined as the difference between the X and Y values estimated by the light, color, and electricity detection system software and the standard light source. The lower the figure, the greater the accuracy.
The conventional light source's spectrum shifts with color temperature. When the color temperature varies, so does the standard spectrum (the general testing equipment will automatically detect the color temperature range of the LED light source under test and determine the matching standard light source color temperature value), and so does the color tolerance. The reference standard spectrum is the same at the same color temperature, but the color coordinates X and Y are different, as is the color tolerance.
Color tolerance unit: SDCM
The color tolerance needed by LED modules for general illumination is less than 7SDCM, according to the performance requirement standard for LED modules.
To guide the development and use of new white LED lighting sources, white LEDs as lighting sources should refer to the color tolerance standard.

All Toppo lighting LED lights will have a color tolerance of less than 5SDCM.
