ものである。[Detailed Description of the Invention] 3. Detailed Description of the Invention [Industrial Applications] The present invention relates to a fluorescent lamp, and in particular to a fluorescent lamp with good light output characteristics and color rendering properties suitable for display lighting for food products, etc. It is related to.

It is possible to make the colors of vegetables look desirable. However, the light output characteristics are very poor at about 70% compared to white fluorescent lamps used for general lighting.

、魚貝類、肉類、野菜類の展示照明には適していない。In recent years, three-wavelength fluorescent lamps with good light output characteristics and excellent color rendering have come to be used for illumination. However, this fluorescent lamp has an average color rendering index Ra of 84.
However, the special color rendering index R9 is as low as 10 to 20, making it unsuitable for display lighting for fish, shellfish, meat, and vegetables.

Rare earth phosphor with emission peak near nm and 660n
We prototyped a fluorescent lamp in which a luminescent layer was formed by coating the inner surface of glass pulp with a mixture of a deep red phosphor with an emission peak near m and a yellow body color, and investigated the color rendering properties and light output. The characteristics and economic efficiency were examined.
その結果、光出力特性及び特殊演色評価数Ｒ９について

生じた。However, in terms of color rendering, Ra is 80 and JISZ93
It was not possible to satisfy the W-SD L color rendering index of 85 as specified in 01. This is due to the visible mercury life (404,7,435-80m). In this fluorescent lamp, a color difference occurs at both ends. For example, F
In L4oSEX, the color difference ΔE is 0.7X10", whereas in the prototype fluorescent lamp mentioned above, the color difference JE is 4.3X.
A very large fruit thinning of 10-3 was obtained. Furthermore, the phosphor mixture material became expensive at 50,000 to 60,000 yen/K.
それ故に、本発明の目的は光出力特性を損なうことなく

て、その範囲を逸脱することは好ましくない。However, if the amount of the blue-green phosphor mixed is less than 5% by weight, the average color rendering index Ra will not be improved, and if it exceeds 30% by weight, the special color rendering index will decrease. If the amount of deep red phosphor mixed is less than 5% by weight, the special color rendering index R9 will not be improved, and if it exceeds 30% by weight, the light output characteristics will be significantly reduced by a factor of 10 or more. Therefore, it is not preferable to deviate from this range.

The average color rendering index Ra and the special color rendering index R9 can be improved.

Furthermore, the coating weight of the light-emitting layer can be reduced, and the price of the fluorescent lamp can also be effectively reduced.

The color difference between the top and bottom of the lamp as well as the light output characteristics (total luminous flux, luminous flux maintenance rate) can be significantly improved. The color rendering index can be significantly improved compared to conventional arrays in which blue-green phosphors and deep red phosphors are not mixed at the same time. Furthermore, the coating weight can be reduced by 30%, and costs can be effectively reduced.

The optical output characteristics can also be significantly improved. Furthermore, the coating weight of the light-emitting layer can be reduced, and the cost of the fluorescent lamp can also be effectively reduced. Furthermore, by mixing a rare earth phosphor with a blue-green phosphor and a deep red phosphor that have a body color in the light emitting layer, mercury lines in the visible range can be suppressed, and the average color rendering index Ua and special color rendering index R9 can be improved.
