For lighting production and adjustment

When using various types of light sources in a room or open space, it is

sometimes necessary to check the color of the lighting.

By using the CL-200A, it is possible to adjust the lighting color so that the

food in a restaurant looks delicious.

For evaluating light source
characteristics

Evaluation of the light distribution of LED illumination modules or the

illuminance distribution of lighting fixtures can be evaluated.

For color-viewing cabinet maintenance

A color-viewing cabinet like that shown at left is used in industries such

as the printing industry to visually evaluate finished work under controlled

conditions. This color-viewing cabinet provides illumination at a specific

illuminance and color temperature by using fluorescent lamps, halogen

lamps, etc. The CL-200A can be used for the daily maintenance and control

of these lamps as well as to indicate when replacement is needed.

For projector light-source
research and color inspection

The CL-200A can be used to measure the white balance and uniformity of

microprojectors, etc. with internal LED light sources. The ability to connect

multiple receptors using LAN cables enables measurement of not only a

single point in the center, but up to a maximum of 30 points over the entire

projected area.

For LED billboard development
and maintenance

The CL-200A enables quality control of the LED modules for digital signage

to be performed easily. If modules with different color tones are used

together, the billboard will look mottled, but by measuring the chromaticity

and color temperature of modules using the CL-200A and selecting

modules based on measured values, billboard uniformity can be achieved.

For accurate measurements of color temperature, use the CL-200A!

Measurement accuracies of CL-200A and photographic color meter

When measuring light sources with non-continuous spectrums such as LEDs, etc., accurate illumination color temperature is

particularly required. The CL-200A can measure color temperature accurately.

CL-2 00A

The CL-200A has sensors that closely match the color-matching functions defined by the CIE (International Commission on

Illumination), enabling precise color measurement. The measurement results can be displayed in various color notations such

as "Correlated color temperature and uv" according to the application.

Photographic color meter

In order to take more beautiful pictures, it is sometimes necessar y to attach filters in front of the camera lens to compensate

for the color of the light illuminating the subject. A photographic color meter is a meter used to select the appropriate filters,

with the sensitivity of its sensors adjusted to match that of the film or digital camera sensor. In addition, because it uses

photographic color temperature, which is calculated based mostly on the blue/red balance of the illumination, large errors

may occur if it is used to measure light sources with non-continuous spectrums.

Color temperature and correlated color temperature

Color temperature

When an ideal blackbody* is heated, it begins to emit light, and as the temperature increases the color of the emitted light

changes from red to yellow to white. Since the color of the emitted light is determined by the temperature of the blackbody,

the color of the light emitted by the blackbody can be expressed as the absolute temperature of the blackbody (in Kelvin).

This color notation scale is called "color temperature". For example, a 7000K color would be the color of the light emitted by

a blackbody heated to 7000K. Figure 1 shows the color of light emitted by a blackbody at various temperatures plotted on an

xy chromaticity diagram. This curve is called the "blackbody locus"; "color temperature" expresses a color on this blackbody

locus.

Correlated color temperature

Since the color of white light emitted by illumination equipment and displays is generally close to the blackbody locus, the
color 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 similar
color expression for colors within a larger region close to the blackbody locus was devised. This is called "correlated color
temperature", 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 the correlated
color temperature but the difference from the blackbody locus, normally in terms of

uv.

Blackbody

*
An ideal radiator. A body which completely

absorbs all incident electromagnetic
radiation. Although a perfect blackbody does
not actually exist, coal is a familiar object
that acts similarly.

Measurements in the LED manufacturing process

When made from blue LED and phosphor

The blue light emitted by the LED mixes with the yellow light

emitted by the phosphor to create white light.

Problem:

Since the spectral emission distribution of the

blue light emitted by the LED varies for each unit,

variations in the resulting white light will occur. Since

usually LED lamps use several LEDs, control of

color mixing is necessar y.

General solution:

Measure the spectral emission

➀

characteristics of each LED element
and rank them accordingly.

Measure the emission characteristics of the

➁

phosphor and rank accordingly.

　Combine the ranked LED elements and ranked

➂

phosphor materials to achieve the desired white
light.

　Inspect the output light quality of the final assembled white LED lamp.

➃

Variations in white light

How the CL-200A can help:

The CL-200A can measure the chromaticity from the phosphor and also

inspect the output light quality of the final assembled white LED lamp.
