2.0.2 Lighting quality
The lighting environment quality of the space where people are located, including indicators such as illuminance (brightness), uniformity, color rendering index, glare index, and lighting coefficient specified in relevant standards.
2.0.3% Flicker (PF)
36
The ratio of the difference between the maximum and minimum output values of the light source's luminous flux and the sum of the maximum and minimum output values of the luminous flux within a fluctuation cycle, expressed as a percentage.
2.0.4 Color rendering
Compared with a reference light source, the light source exhibits the characteristics of object color.
2.0.5- General color rendering index
The average color rendering index of the light source for samples of the 1st to 8th standard colors specified by the International Commission on Illumination (CIE), commonly known as the rendering index.
2.0.6 Special color rendering index RThe color rendering index of the light source on the 9th standard color sample selected by the International Commission on Illumination (CIE)
2.0.7 Chromaticity tolerances (SDCM)
Characterize the deviation between each light source in a batch of light sources and the rated color of the light source, represented by the color matching standard deviation (SDCM).
2.0.8 Threshold Increment (TD)
