In a color-enhanced illumination device having a cutoff absorption means, as the cutoff absorption means, the chromaticity on the standard chromaticity diagram of the main wavelength passing through the chromaticity point of the light source color with respect to the chromaticity point of the object color to be emphasized A cut-off absorbing means for cut-off absorbing color components is used.

ことになる。[Operation] According to the present invention, therefore, the color component of the dominant wavelength passing through the chromaticity point of the light source color is cut off and absorbed with respect to the chromaticity point of the object color whose chromaticity on the standard chromaticity diagram is to be emphasized. Since the blocking absorption means is used, the background color of the irradiated object has a complementary color of the object color of the irradiated object, so that the color of the irradiated object itself appears more emphasized.
［実施例］ 以下本発明を実施例により説明する。[Examples] The present invention will be described below with reference to Examples.
第１図は一実施例の分解斜視図を示し、この実施例では
スポットライト１の光源からの光の色成分を部分的にし

３をスポットライト１の灯具本体に固定することにより
フィルタ２をスポットライト１の前面に配置している。FIG. 1 shows an exploded perspective view of one embodiment. In this embodiment, a filter 2 for partially blocking color components of light from a light source of a spotlight 1 is fitted into a mounting frame 3 and the mounting frame 3 The filter 2 is arranged in front of the spotlight 1 by fixing the filter 2 to the lamp body of the spotlight 1.
このフィルタ２の特性は第２図に示す標準色度図上の色
度が強調すべき被照射物の物体色の色度点Ａに対して光
源色の色度点Ｃを通る主波長Ｂの色成分（色相）を部分
的にしゃ断するものを使用する。The characteristic of this filter 2 is that the chromaticity on the standard chromaticity diagram shown in FIG. 2 has a dominant wavelength B passing through the chromaticity point C of the light source color with respect to the chromaticity point A of the object color of the object to be illuminated. Use one that partially blocks the color component (hue).

になる。Therefore, the object color is emphasized in comparison with the light source color, and by setting the transmittance within the range of 20 to 70%, for example, the incoming energy does not change the color of the irradiated object itself and the incoming energy includes the color sufficiently. However, unless the background color is the same as the color of the object to be irradiated, the object color of the object to be irradiated is complemented, and the color of the object to be irradiated is emphasized by comparison with the object color.

るのである。In the above examples, the object to be irradiated was meat, ham or sausage having a main wavelength of 595 to 620 nm. As shown in the chromaticity diagram, by blocking the component including the hue of 595 to 610 nm (orange) from the light source color with the filter 2, the irradiated object looks emphasized. In addition, meat, ham, and sausage are discolored due to oxidation of dye (increasing metmyoglobin) at 560 to 630 nm light, but as described above, the color component corresponding to this wavelength is blocked to prevent dye oxidation. Therefore, discoloration can be prevented.
尚余色とは、白色の光りから夫々の波長の光の色を取り
除いた残りの色であり、光の波長と色及び余色の関係は
下表のようになる。Note that the extra color is the remaining color obtained by removing the color of the light of each wavelength from the white light, and the relationship between the wavelength of the light and the color and the extra color is as shown in the table below.

95〜610nmとしている。 Although the filter 2 is used in the above-described embodiment, the same effect can be obtained in an illuminating device that uses a reflecting plate composed of a film having a spectral reflectance characteristic as shown in FIG. Also in this case, the object to be irradiated is meat, ham or sausage having a main wavelength B of 595 to 620 nm, and the absorption range D is hue 75.
It is set to 95 to 610 nm.

Since the background color of the irradiated object has a complementary color of the object color of the irradiated object, the color of the irradiated object itself appears more emphasized, and the irradiated object is dyed with light of a certain wavelength. Even when the oxidization occurs and the discoloration occurs, it is possible to prevent the oxidization of the dye and prevent the discoloration by blocking the color component corresponding to the wavelength. There is an effect.
