III  Applications

3.1 LED and solid-state lighting source spectrum, Lv, color temperature, color rendering index, uniformity, dominant wavelength, S/p, luminous flux and other parameters test

      CI350 color luminance meter stand-alone instrument can easily realize spectrum, Lv, color temperature, color rendering index, dominant wavelength, S/P, peak wavelength, plant lamp parameters, flash measurement, camera white balance and other parameters measurement.

      The luminous flux can be measured by integrating sphere. With the help of professional HIQC software, the chromaticity coordinate measurement and classification of LED solid-state light source can be easily realized.

3.2 Lv, color temperature, color rendering index, dominant wavelength measurement for library and office lighting sources

     Many lighting standards have certain requirements for the Lv, color temperature, color rendering index and other indicators of municipal engineering lighting and office lighting. CI350 color illumination can be used to measure the above indicators in real time.

3.3 Lv and chromaticity coordinates  measurement of Display panel/LCD

     The display panel/LCD will be lit and preheated for half an hour. CI350 probe is attached to the display panel/LCD surface. The control display panel/LCD displays different colors, and the CI350 spectroradiometer measures the Lv, chromaticity coordinates and radiance spectrum of the display panel/LCD, and then calculates the color gamut, uniformity of the display panel/LCD, and can do GAMMA/DICOM/color correction.
