The importance of color rendering index for LED indoor lighting:
With the expansion of LEDs in indoor lighting applications, how to develop lamps that are more suitable for indoor lighting has become the focus of many companies. Insiders pointed out that when developing LED indoor lighting fixtures, it is necessary tofocus on indicators such as light efficiency, CRI, color
temperature and light distribution.
Among them, light efficiency and CRI are the two most important indicators for evaluating the quality of LED lamps. Luminous efficiency determines the brightness and energy-saving efficiency of the lamps. The CRI determines the degree of color reduction of the lamps, that is, the color difference of the illuminated object.
In fact, the industry's pursuit of high color rendering index and high luminous efficiency of LED lighting products has never stopped. But theoretically speaking, high color rendering index and high luminous efficiency are a pair of contradictions, and there is aninverse relationship. How to find the balance between them is the key to the breakthrough of indoor lighting technology.
Previously, everyone only focused on the high luminous efficiency of the light source, while the color rendering index (Ra) was ignored by everyone. The color rendering index represents the deviation of the color of an object from the color of the reference light (sunlight) under illumination, and can more fully reflect the color characteristics of the light source. To correctly express the original color of the object, it is necessary to use a light source with a high color rendering index, whose value is close to 100, the better the color rendering.
Industry insiders pointed out that the future LED indoor lighting fixtures must have the characteristics of high CRI and high luminous efficiency. Without high CRI, there is no light art at all.
EPluxx has always attached great importance to these two indicators. In the range of color temperature of 4000K, when the color rendering index is greater than 90, compared with similar products, our light source has higher luminous efficiency. Adhering to the concept that a good panel light must have a good light source, taking natural light as the starting point, and demanding more professional product indicators, each panel light is anti-glare, high luminous efficiency, and high color rendering index.
