EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of CIE 177 testing. CIE 177 is a standard that contains information on measuring and evaluating the color appearance of white LED light sources.
White LEDs are produced by placing a yellow phosphor layer on top of a blue or purple LED. Therefore, the color spectrum of white LEDs shows a wavy spectrum rather than a continuous spectrum like conventional filament lamps or other light sources.
CIE 177 defines a specific color chart to ensure that the spectrum of white LEDs accurately reflects the natural colors of colored objects. This chart is a standard method for measuring the color characteristics of white LEDs.
To evaluate the color performance of white LEDs, it is necessary to look at properties such as color temperature and color chart. Color temperature is measured in Kelvin (K), which describes whether light feels "warm" or "cool". The color chart is evaluated using many different measurement methods, such as CRI (color accuracy index), which measures the colors of light.
