Abstract

PURPOSE: To make color rendering of the skin of Japanese women beautiful and make raw meat and raw fish look fresh by providing a means for suppressing output of lmninous energy in yellow and red wave length bands. CONSTITUTION: Output of luminous energy in a yellow wave length band and a red wave length band, or the wave length band from around 570nm to around 630nm is easily suppressed by controlling a multilayer interference film commercialized with a halogen lamp. Chromaticity region of the skin color for making the skin of Japanese women belonging in the yellow race look beautiful by illumination is reproduced. Yellowish color of a neodymium lamp is removed, clear photo color is maintained, and the skin of Japanese women makes look like beautiful.

2. Description of the Related Art As a conventional method for quantitatively evaluating the color rendering properties (color appearance) of an illumination lamp, there is a "color appearance fidelity evaluation method". This is a method that quantitatively evaluates how faithfully the target illumination lamp reproduces color compared to the reference light, and is currently specified by JIS Z 8726 "Light source color rendering evaluation method". , Average color rendering index Ra
It is represented by the numerical value of. On the other hand, in addition to evaluation of the fidelity of color appearance, research has recently been conducted on "a method for evaluating the preference of color appearance". This method is a method of quantitatively evaluating whether the target illumination lamp has a color shift when compared with the reference light, but whether the color shift is in a preferred direction or a preferred direction. .
This means that the preferred direction of color shift differs depending on the object to be illuminated.

It is well known that, for example, foods such as fresh meat and fresh fish have an effect of appearing fresh by vividly rendering the color of fresh meat and fresh fish by removing yellowing. Therefore, in order to absorb the emission energy around 580nm, neodymium bulbs with neodymium mixed in the bulbs of incandescent bulbs are already sold by various lighting manufacturers. It is known that this effect has the same effect in other illumination lamps such as a fluorescent lamp.

However, there has not been considered any means for reproducing all of the chromaticity region of the skin color that makes the skin color of a Japanese woman beautifully and beautifully by the illumination light. In addition, the above-mentioned yellow wavelength band, that is,
With neodymium light bulbs that absorb the wavelength band near 580 nm, the yellowing characteristic of light bulbs is removed and the light color is refreshed, and fresh meat and fish have the effect of looking fresh, but the skin color of humans tends to shift As will be described later with reference to FIG. 2 as an example, the direction is different from the preferred direction, so that the skin color of the Japanese woman could not be made beautiful and beautiful. In other words, there was no illumination lamp that had a light color that was unique to the light bulb and had a clean light color, and that had two functions that could make the Japanese woman's skin color look beautiful and beautiful.

That is, color shift occurs in the preferred skin color direction, and 580n
Since the yellow wavelength band of m, 585nm is omitted, the light color of the illumination light is a neat light color that removes the yellowing peculiar to light bulbs.
Fig. 9 shows the values of the luminescence energy of the incandescent light bulb from 81 at 5nm intervals from 380nm to 780nm to 580nm and 585n in the yellow wavelength band.
3 shows the spectral distribution of emission energy excluding m and 630 nm and 635 nm in the red wavelength band.

As is clear from the above examples, 570 nm
By suppressing the emission energy output from around 630 nm, it is possible to reproduce the chromaticity region of the skin color that makes the skin color of the Japanese woman of the yellow race beautiful and beautiful by the illumination light. In addition, the yellowing that is characteristic of neodymium bulbs can be removed and the light color can be kept clean, and the skin color of Japanese women can be shown beautifully and beautifully.

Yellow wavelength band and red wavelength band, that is, 570n
The method of suppressing the emission energy output from around m to around 630 nm can be easily realized by controlling the multilayer interference film that is practically used in the halogen bulb. That is, 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 produced (for example, "National Technical Report").

Incidentally, FIGS. 1 and 5 to 7 shown in the embodiment,
The same effect can be obtained even if the spectral distribution of emission energy as shown in FIGS. 9 and 11 is not limited to one illumination lamp and is output by a transmission plate or a reflection plate of a lighting fixture, or an illumination device including a plurality of illumination lamps. It goes without saying that you can get it. For example, the multilayer interference film that transmits or reflects in the direction different from the direction of illuminating the emission energy of the yellow wavelength band and the red wavelength band, and transmits or reflects in the direction of illuminating the emission energy of the other visible wavelength band. It may be configured to include the applied transmission plate and reflection plate. Further, in an illuminating device composed of two or more types of illuminating lamps, the output of emission energy in the yellow wavelength band and the red wavelength band of the mixed illumination light is smaller than that in the other visible wavelength bands. The lighting device may be a suppressed lighting device or a lighting device in which two or more types of lighting lamps are combined.
