What is the color rendering index (CRI)?
The color rendering index of a light source is a parameter that refers to the Ability of the Light Source
To reproduce the color of an object.
Mainly used to Define the difference in the chromaticity of the LED light source,
And the score of this index is in the range of 0-100.
Simply put:
Color rendering is an important aspect of Testing the quality of lighting
The higher the color rendering index, the better the color rendering of the light source,
The stronger the ability to restore the color of the object.
General color rendering index Ra the larger,
The better the color rendering performance; conversely, the worse the color rendering.
As the LED lamps and lanterns are produced by the blue chip excitation yellow phosphor and white light,
It is extremely missing in the red band, resulting in LED lamps and lanterns is no red display ability.
When we choose LED lamps and lanterns,
We should not only go to see the color rendering index Ra, but also look at the value of R9 and R15.
General lamps and lanterns show index recommended Ra>90 ( R9>50, R15>90).
In home lighting design, to create a healthy and good atmosphere,
The correct choice of light source and lamps and lanterns is particularly important.
In order to make the life of the light show people's color better, the color of food and fruit realistic,
The choice of lamps and lanterns need to choose the higher the better, that is, the RA value must be high.
Long-term use of too low lighting color rendering index affects the Eye's recognition of the object color,
So that the object can not show its true color, this situation, if continued,
Will lead to a decline in the ability to identify the color and decline,
And may cause color blindness and color weakness and other Serious vision problems and Eye diseases.
Why choose high color rendering index?
1、 High color reproduction: high color saturation.
2、 Prevent myopia.
3, to meet the needs of users.
Solve the user's pain points: things are not real under the light, protect the eyesight of small children.
