With the popularization of LED lighting technology, consumers are paying more and more attention to light quality when purchasing lamps. CRI (color rendering index), as an important indicator to measure the color rendering ability of light sources, has become one of the key parameters for judging the performance of LED lamps. So, Let's take a look at what CRI is.
[Definition and significance of CRI index]:CRI (Color Rendering Index) is an indicator used to evaluate the ability of a light source to restore the true color of an object. Its value ranges from 0 to 100. The higher the value, the better the color rendering of the light source. The CRI of natural light is 100, while the CRI of high-quality LED lamps can usually reach more than 80, and high-end products can even reach more than 95, which can present the color details of objects more realistically.
In home, commercial and industrial lighting scenarios, the level of CRI index directly affects the visual experience. For example, in art galleries, clothing stores or cosmetics counters, high CRI lighting can accurately restore the true colors of exhibits and avoid color differences; in home environments, high CRI lamps can make food, furniture and decoration colors more vivid and improve comfort. On the contrary, low CRI light sources may cause color distortion, and long-term use may even cause visual fatigue.
Color rendering and health: If you are under a light source with poor color rendering for a long time, it is easy to cause eye fatigue and even myopia. Too low classroom lighting color rendering index affects people's eyes to recognize the color of objects, so that objects cannot show their true colors.
Color rendering and illumination: The color rendering index of the light source and the illumination together determine the visual clarity of the environment. There is a balance between illumination and color rendering index. When using a lamp with a color rendering index Ra>90 to illuminate an office, the illumination can be reduced by more than 25% in terms of the satisfaction of its appearance compared to an office illuminated by a lamp with a low color rendering index (Ra<60).
Therefore, it is particularly important to choose a suitable CRI value. For ordinary home lighting, LED lamps with CRI ≥ 80 can be selected, while places with strict color requirements (such as design studios and medical environments) should choose products
with CRI ≥ 90. In addition, consumers should note that CRI is not the only standard, and it is also necessary to consider parameters such as color temperature and light efficiency.
At present, LED lamps with high CRI are needed in many places. In LIPER philosophy: CRI greater than 80 is just a starting point. What LIPER want to do is to ensure that every user can use LED lamps with CRI greater than 90!
In the era of LED lighting, the CRI index has become an important yardstick for measuring light quality. When purchasing, consumers should choose products with excellent color rendering according to their own needs to obtain a healthier and more comfortable lighting experience.
