Description of the Related Art Conventionally, incandescent light bulbs and color rendering improved fluorescent lamps have been mainly used for displaying and illuminating fresh foods among foods. Of these, the latter has an excellent color rendering performance, so it has the characteristic that it can be seen as much as it was viewed in natural light, but it has the effect of motivating those who purchase the food, that is, it makes the food look preferable. It has no effect. Fluorescent lamps, including improved color rendering fluorescent lamps, have a problem that the red component is insufficient, and the freshness of the food looks visually inferior.On the other hand, incandescent light bulbs look good, but compared to fluorescent lamps. Since there is a lot of heat radiation, there is a big problem that the freshness of food is deteriorated in a short time.

作用 発明者らは前記問題点を解決するため、生鮮食品を好ま
しく見せるランプ光色について実験した結果、従来のよ
うに単に赤色のみを強調したのでは不十分で、青色のう

不足して好ましく見えなくなることが判明した。従来の
食品照明を目的とした蛍光ランプは400〜460nmの発光エ
ネルギーが不足しているため、R12/R9が前記範囲を下ま
わり、単に赤色を強調するだけで他の色とのバランスが
極めて悪かった。R12/R9が前記範囲内のものは赤色は十
分に強調されるとともに青色とのバランスがよいので、
特に従来の食品の照明を目的としたランプでは全く無視
されていた白色が好ましく見える結果、食品全体が好ま
しく見えることを見い出した。In order to solve the above problems, the present inventors have conducted an experiment on a lamp light color that makes fresh food preferable, and it is not sufficient to emphasize only red as in the conventional case. Among blue, 400 to 460 nm is particularly preferable. It was found that the balance between the luminescence energy in the region and the red luminescence energy is important. As a result of various studies on the evaluation method, it was found that the color rendering index can be evaluated by the ratio of the special color rendering index R 12 (blue) to the special color rendering index R 9 (red), that is, R 12 / R 9 . According to the experiments by the inventors, 400
Energy of ~460nm is the R 12 / R 9 preferably has a value in the range of 0.9 to 1.8, the lamp light color falls below this range discomfort redness becomes stronger increases, the color of everything redness It has been confirmed that the appearance itself is significantly reduced due to the increase in the appearance. On the other hand, when the energy amount of 400 to 460 nm corresponds to a value where R 12 / R 9 exceeds the above range, the lamp light color becomes too bluish and becomes bluish purple, and the redness of fresh food is insufficient. It turned out that it did not look good. Conventional fluorescent lamps for food illumination lack emission energy in the range of 400 to 460 nm, so R 12 / R 9 is below the above range, and the balance with other colors can be achieved by simply emphasizing red. It was extremely bad. When R 12 / R 9 is within the above range, red is sufficiently emphasized and well balanced with blue,
In particular, it was found that as a result of the white color, which has been completely ignored by conventional lamps for the purpose of illuminating food, being preferable, the food as a whole looks preferable.
