The difference between the formula calculated by the computer and the target standard.

Color tolerance refers to the difference between the formula calculated by the computer and the target standard. It is calculated under a single lighting source. The smaller the value, the higher the accuracy. However, it should be noted that it only represents the color comparison under a certain light source, and cannot detect the deviation under different light sources. The difference between the spectrum emitted by a light source and the standard spectrum.

Explain

Color tolerance refers to the difference between the formula calculated by the computer and the target standard. It is calculated under a single lighting source. The smaller the value, the higher the accuracy. However, it should be noted that it only represents the color comparison under a certain light source, and cannot detect the deviation under different light sources. The difference between the spectrum emitted by a light source and the standard spectrum.

Definition

The color tolerance is the difference between the X, Y values calculated by the software of the light, color and electricity detection system and the standard light source. The smaller the value, the higher the accuracy.

The spectrum of the standard light source changes with the color temperature. When the color temperature is different, the standard spectrum is different (the general testing equipment will automatically identify the color temperature range of the LED light source under test and determine the corresponding standard light source color temperature value), and the color tolerance is different. At the same color temperature, the reference standard spectrum is the same, but the color coordinates X and Y are different, and the color tolerance is different.

Color tolerance unit: SDCM

The performance requirement standard of LED modules for general lighting stipulates that the color tolerance required by LED modules should be less than 7SDCM.

White LEDs as lighting sources should refer to the standard of color tolerance to guide the development and application of new white LED lighting sources.

The color tolerance will be less than 5SDCM for all LED lights from Laisi lighting.
