Is Color Rendering Index Important for Pendant LED Light ?

CRI (color rendering index) is an important parameter for measuring the color rendering performance of a lamp. It indicates the lamp's ability to restore the true color of an object. The higher the CRI, the better the color rendering performance of the lamp, which can better present the color of the object and improve the visual effect and recognition. The International Commission on Illumination (CIE) sets the color rendering index (Ra) of sunlight as 100, and the color rendering index of other light sources is lower than 100.

 

With the development of LED chip technology, people have higher and higher requirements for CRI. From the previous color rendering index of no less than 70 to the current color rendering index of no less than 90.

In office lighting pendant led light CRI has an important impact on employees' reading, writing, communication and work efficiency. If the CRI of the lamp is low, it will cause color distortion of objects, affect employees' visual perception and judgment, and even cause visual fatigue and discomfort. So it is very important to choose office lighting fixtures with high CRI, which can provide better lighting quality and visual comfort, and improve employees' work efficiency and reading quality. Currently, office lighting requires CRI to be higher than 80, and reading and writing areas require CRI to be greater than or equal to 90. In addition to CRI, many places currently have specific requirements for R9. For the same CRI, a lighting environment with R9 higher than 60 makes people more comfortable.

 

In addition to CRI, office lighting fixtures also need to consider factors such as illumination, uniformity, and color temperature to meet the lighting needs of different areas and uses. At the same time, it is also necessary to pay attention to issues such as energy efficiency, energy conservation and environmental protection of lamps to reduce energy consumption and carbon emissions and improve lighting quality and sustainability.
