Description of the Related Art At present, as a method for quantitatively evaluating the color rendering of a light source, there is a "method for evaluating the fidelity of color appearance". This is a method for quantitatively evaluating how faithfully the target lamp reproduces the color compared to the reference light, and is currently specified in JIS Z 8726 "Method for evaluating the color rendering of light sources". It is represented by the numerical value of the average color rendering index Ra.
At present, discharge lamps are also being developed with the aim of improving the average color rendering index Ra and the brightness efficiency.

In this method, the target lamp has a color shift when compared with the reference light.
This is a method for quantitatively evaluating whether there is a shift in an undesirable direction. This evaluation of the favorableness of color appearance is one of the important color rendering characteristics of a light source, but a standardized method has not yet been determined to date.

In particular, since the test color that greatly contributes to the conspicuousness is red, the area surrounded by the red, blue, and green test colors and the area surrounded by the red, yellow, and green test colors are based on the red test color. The sum of the areas was defined as the color gamut area of the four test colors. Based on the color gamut area of the four test colors, the conspicuous index M is given by equation (1).

カットしない場合よりも高くなることがわかる。The higher the conspicuous index M is, the more conspicuous a color object such as fresh flowers or green leaves can be. Therefore, various lighting lamps from 380nm to 780nm
The change of the conspicuous index M was determined for 41 types of illumination lamps prepared by cutting the spectral radiation intensity in the visible wavelength range at every 10 nm. FIG. 1 shows an illumination lamp having a spectral emission intensity of 3000 K of blackbody radiation, which was prepared by cutting the spectral emission intensity in the visible wavelength range from 380 nm to 780 nm every 10 nm as described above.
Changes in the conspicuous index M are shown for 41 types of illumination lamps. The horizontal axis in FIG. 1 indicates the cut wavelength, and the vertical axis indicates the value of the conspicuous index M. As is clear from FIG. 1, it is understood that the value of the conspicuous index M is higher when wavelengths around 480 nm to around 510 nm and around 560 nm to around 600 nm are cut than when no wavelength is cut.

In the case of transmitted light, reflected light, and mixed light of transmitted light and reflected light, the method can be easily realized by controlling a multilayer interference film that is put into practical use, for example, in a halogen bulb. . In other words, the complex reflectance can be freely determined as a design target value from the optical film thickness and the number of thin films, and an arbitrary multilayer interference film can be manufactured (for example, in the “National Technical Report” (Na

Needless to say, if the wavelength region to be reduced is increased in the vicinity wavelength region or the wavelength region from around 560 nm to around 600 nm, the eye-catching effect increases as the wavelength region to be reduced increases. Also, if the entire wavelength region from around 480 nm to around 510 nm, and from around 560 nm to around 600 nm is reduced, the eye-catching effect is highest, but from around 480 nm to 510 nm.
Even if the entire wavelength region in the vicinity or the entire wavelength region from around 560 nm to around 600 nm is reduced, a good eye-catching effect can be obtained.
