Color rendering index , abbreviation of CRI.
The indicator is used to determine the amount of light available to detect colors.
The human eye has grown so large that it can detect different colors of objects using sunlight.
As a result, sunlight is the best indicator for the human eye.
Because it makes it easy for people to recognize natural colors.
Sunlight has a full spectrum of light, so all colors can be seen at different color temperatures under the sun.
While other light sources have different spectra of light, different light spectra can be found by searching for different sources.
Considering what was said above about the suitability of sunlight in human eyes for color recognition.
Light sources are closer to the spectrum of light than natural sunlight.
In this regard, the Color Spectrum Index (CRI) is used to determine the quality of the light source, which ranges from zero to 100.
By this description, the light where color recognition is impossible is zero, and the light that has the best color display has one hundred indicators.
Better optical resolution is directly correlated with higher CRI percentages.
CRI suitable for color resolution is provided for a 1 to 2 percent light source.
There are many reasons today that there is a growing tendency to use LED lamps.
The most important of these are the color indicators in these lamps.
This level of quality is present in LED lamps and the fact is that they do not have infrared and ultraviolet rays.
Valuable benefits such as:
Non-threatening eye and environmental health, providing high quality light and meeting the needs of the human eye in industrial work environments that require high color accuracy and recognition.
The standard of light produced makes it beautiful to use.
