Dear customer, let me introduce the CRI (Color rendering index) of indoor led light.
The color rendering ability of a light source to an object is called color rendering, which is compared with the appearance of the object under the same color temperature or reference light source (incandescent lamp or painting light). Light sources of the same light color have different spectral compositions, and light sources with a wider spectral composition are more likely to provide better color rendering quality. When there is little or lack of the main wave reflected by the object under the reference light source in the light source spectrum, the color will have obvious chromatic aberration. The greater the degree of chromatic aberration, the worse the color rendering of the light source.
Color classification:
1. Faithful color rendering:
A light source with a high color rendering index (Ra) must be used to correctly express the original color of the substance, and its value is close to 100, and the color rendering is the best.
2. Effect color development:
To sharply emphasize a specific color, and express the beauty of life, you can use the method of additive color to enhance the color rendering effect. Using a low color temperature light source to illuminate can make the red more vivid; using a medium color temperature light source to illuminate, so that the blue has a cool feeling; using a high color temperature light source to illuminate, make the object feel cold.
General application of CRI) grade :
90-100 1A Excellent, Places where precise color contrast is required (as bread store and fabrics shop, car and fruit shop in above picture)
80-89 1B / Places that require correct color judgment(like jewelry store)
60-79 2 Normal ,Places requiring medium color rendering
40-59 3 / Places with low requirements for color rendering and small color difference
20-39 4 Poor Places with no specific requirements for color rendering.
