LED lamp bead manufacturers briefly describe how the "color rendering" of the light source is used in the home interior lighting


Objects will produce different color effects when illuminated by different light sources, which is the "color rendering" of the light source. For example, under the illumination of a fluorescent lamp, red becomes unclear and yellow is emphasized. Under the illumination of the incandescent lamp, the red is emphasized, and the cyan becomes unclear. Under the illumination of the red light source, the green object appears dim. Under the illumination of the yellow light source, the purple object loses its vividness. Only under the illumination of a kind of high color rendering fluorescent lamp, the object can correctly reflect its true color. According to the principle of Zhongshan bulb lamp, how to use different light colors to illuminate objects in different furnishings in the room to make them show strange brilliance effects is also a creative art of lighting in homes, which can enrich people's visual perception.

In addition, indoor lighting methods can generally be divided into direct lighting, indirect lighting and scattered light lighting. Direct lighting has concentrated light, indirect lighting is soft, and the effect of scattered light is between the above two. If it can be used in a clever combination, it varies from object to object, complements each other with indoor furnishings, and creates a mysterious and unpredictable light and shadow environment.


The degree to which the light source presents the color of the object is called color rendering, which is the degree of vividness of the color. The light source with high color rendering has better color performance, and the color we see is closer to the natural color, and the light source with low color rendering The color performance is poor, and the color deviation we see is also larger.

Why is there a difference in color rendering? The key lies in the spectral characteristics of the light. The wavelength of visible light is in the range of 380nm to 780nm, which is the red, orange, yellow, green, cyan, and blue we see in the spectrum. The range of purple light. If the proportion of the various colors contained in the light emitted by the light source is similar to that of natural light, the colors seen by our eyes will be more realistic.

LED bulb manufacturers say that the color rendering index is generally used to characterize color rendering. The standard color is set at 100 under the radiation of a standard light source. When the color standard is illuminated by the test light source, the degree of visual distortion of the color is the color rendering index of this light source. The larger the color rendering index, the less distortion, on the contrary, the greater the distortion, the smaller the color rendering index. Different places have different requirements for the color rendering index of the light source.
