III  Applications

(Note:CL500 and CL800 operation mode is the same, the picture of some instruments using CL800 for demonstration)

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

      CL500 color illuminometer stand-alone instrument can easily realize spectrum, Ev, 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 Color temperature(CCT), Color rendering index(CRI), Uniformity measurement of Light  box or Display panel

      The main technical indexes of the light box include the following: the standardization of the spectral distribution of the light source, the display uniformity of the illumination of the light source, the stability of the light source, the color temperature and color rendering index of the light source, and the life of the light source. CL500 color illuminometer can easily measure the stability, uniformity and spectral matching of the light box.

3.3 Transmittance Test

       Transmittance is the ratio of the luminous flux (radiant flux) of light passing through the measured object to the incident luminous flux (radiant flux) . The transmittance of visible light is usually the ratio of the luminous flux of visible light at wavelengths of 380-780 nm, UVA transmissivity is usually the ratio of UVA to UVA radiation flux, and IR transmissivity is the ratio of IR radiation flux at wavelengths over 780 nm.

       LED light source or halogen tungsten lamp is usually used as the lighting source in the transmissometer. From the test results, different lighting sources have a certain influence on the transmittance test results, usually affecting about 5% .

       Many standards and documents clearly state that the D65 standard illuminator is the most ideal illuminator for transmissometers. The D65 standard lighting source is the Earth's average northern hemisphere solar spectrum, so the transmittance tested under this light source condition is very representative and easily accepted by the public. For example, outdoor glass, UV sunscreen glasses and other related standards clearly state that the D65 light source should be used for transmittance testing. However, the light source used by the common transmittance meter is far from the D65 standard lighting source, so the test results are not very good.

      CL500 color illuminometer can use outdoor sunlight (as close as possible to the D65 standard lighting source) as the lighting source, after two tests, very convenient test glasses, architectural glass in D65 standard lighting source under the condition of transmittance.

3.4 Illuminance, color temperature, color rendering index, dominant wavelength measurement for library and office lighting sources

       Many lighting standards have certain requirements for the illumination, color temperature, color rendering index and other indicators of municipal engineering lighting and office lighting. CL500 color illumination can be used to measure the above indicators in real time.
