The ability to connect multiple receptors using LANcables enables measurement of not only a single point inthe center, but up to a maximum of 30 points over the entireprojected area.For LED billboarddevelopment andmaintenanceThe CL-200A enables qualitycontrol of the LED modules fordigital signage to be performedeasily. If modules with differentcolor tones are used together, the billboard will look mottled,but by measuring the chromaticity and color temperature ofmodules using the CL-200A and selecting modules based onmeasured values, billboard uniformity can be achieved.Multi-point illuminance measuring systemzz 5-point example: Architectural lighting, etc. zz 9-point example: Projectors, etc.[CL-200A 9 point measuring system composition]Chroma Meter CL-200A1 unitCL-200A Receptor Head8 unitsAdapter Unit for Main Body T-A201 unitAdapter Unit for Receptor Head T-A21 9 unitsAC Adapter1 unitData Management Software CL-S10w 1 setzz 25-point example: Street lighting, etc.Chroma Meter CL-200A7

For accurate measurements of color temperature, use the CL-200A!CL-200AThe CL-200A has sensors that closely match the CIE*-defined color-matching functions which are intended to correspondto the response of the human eye to enable precise color measurement. The measurement results can be displayed invarious color notations such as "Correlated color temperature and uv" according to the application.*CIE: International Commission on illuminationPhotographic color meterIn order to take more beautiful pictures, it is sometimes necessary to attach filters in front of the camera lens to compensate forthe color of the light illuminating the subject. A photographic color meter is a meter used to select the appropriate filters, with thesensitivity of its sensors adjusted to match that of the film or digital camera sensor. In addition, because it uses photographiccolor temperature, which is calculated based mostly on the blue/red balance of the illumination, large errors may occur if it isused to measure light sources with non-continuous spectrums.[Actual measurement data for daylight-color LED bulb]Color-temperature difference fromMeasured color temperaturestandard-instrument measured valueOur company's standard instrument5,0450CL-200A5,011-34Photographic color meter5,600555Color temperature and correlated color temperatureColor temperatureWhen an ideal blackbody* is heated, it begins to emit light, and as the temperature increases the color of the emitted lightchanges from red to yellow to white. Since the color of the emitted light is determined by the temperature of the blackbody, thecolor of the light emitted by the blackbody can be expressed as the absolute temperature of the blackbody (in Kelvin). This colornotation scale is called "color temperature". For example, a 7000 K color would be the color of the light emitted by a blackbodyheated to 7000 K. Figure 1 shows the color of light emitted by a blackbody at various temperatures plotted on an xy chromaticitydiagram. This curve is called the "blackbody locus"; "color temperature" expresses a color on this blackbody locus.Correlated color temperatureSince the color of white light emitted by illumination equipment and displays is generally close to the blackbody locus, thecolor of such light sources is normally expressed using "color temperature".However, the color of such light sources is not directly on the blackbody locus. Because of this, a way to enable similarcolor expression for colors within a larger region close to the blackbody locus was devised. This is called "correlated colortemperature", and the larger region is shown by the isotherms on the xy chromaticity diagram in Figure 2.To accurately express the correlated color temperature of a light-source color, it is necessary to state not only thecorrelated color temperature but the difference from the blackbody locus, normally in terms of uv.0.00Chroma Meter 00.254704604500.0480380〜4400.10 0.20 0.30 0.40 0.50 0.60 0.70xFigure 1: Blackbody locus on xy chromaticity diagram80.300650131000000490300.100.3530002500 2000 5903500*4000A60015004500D55 * * B610D65 **D75 * 4555040005100.70054015object that acts similarly.0.5053000blackbody does not actually exist, coal is a familiar5200.80020incident electromagnetic radiation.

The vision of the human eye under low-light conditionsis termed “scotopic vision”, with a sensitivity peak wavelength which is shiftedtoward the shorter wavelengths compared to vision under bright conditions,which is termed “photopic vision”. The respective spectral luminous efficiencycurves for each type of vision are shown at right.Convenient measurement functions1) Continuous measurement mode :For monitoring changes in illuminance levels or spectralpower distribution.2) Display of the average of multiple measurements :Useful for evaluation of projectors, etc.3 Delayed-measurement function :The CL-500A can be set to wait for a specific timeafter the measuring button is pressed before startingmeasurements, so you can get out of the way before themeasurement is taken to make sure that light reflectedfrom you or your clothes do not affect measurements.4) Display of data at specific wavelength :Allows monitoring of spectral irradiance at a specificwavelength.

W h a t i s c o l o演r-色rene rはing proper ty?性dとColors are generally compared by arranging objects side-by-side and looking atthem under natural light (sunlight).When comparing how lamps such as fluorescent lamps, LEDs (light emittingdiodes), etc. make objects look against how natural light makes them look, howclosely the appearances match is called the “color-rendering property” of the lamp.A lamp that produces a hue similar to that of natural light is said to have a good (high)color-rendering property. The color-rendering index is an objective quantificationof the color-rendering properties of a light source. The color-rendering indexexpresses the comparison between the light source being tested and a standardilluminant*. The maximum value is 100, with the value decreasing as the colorrendering difference increases, indicating how far the appearance under the testlight source is from the natural color under sunlight.Standard illuminant(CIE daylight)Light sourcebeing tested* Standard illuminant with the same color temperature as the light source beingtested.
