Abstract

PURPOSE:To obtain a fluorescent lamp which gives the same optical color, freshness and whiteness as a fluorescent lamp of the three-wavelength-range emission type by using a phosphor film consisting of a calcium halophosphate having a specified chromaticity range and yttrium oxide activated with europium. CONSTITUTION:A phosphor film is obtained by mixing a calcium halophosphate phosphor activated with antimony and manganese with a yttrium oxide phosphor activated with trivalent europium. When the above calcium halophosphate is used in a lamp, its chromaticity point is located on a line connecting the center (x=0.330, y=0.361) of a circle and the center (x=0.330, y=0.366) of a circle in oblique xy-coordinates, used to deform the MacAdam's deviation ellipse into a circle, and located in a circle having a diameter of 5SDCM. For instance, in order to adjust the mean color rendering index to not less than 75: addition of 0% of yttrium oxide activated with europium is necessary for a calcium halophosphate phosphor located at point (S) in the figure; addition of about 5% is necessary for that located at point (T); and addition of about 10% is necessary for that located at point (U).

DETAILED DESCRIPTION OF THE INVENTION Field of Application: Industry The present invention relates to a fluorescent lamp.Constitution of a conventional example and its problems Conventionally, as a fluorescent lamp with improved color rendering property, a blue-emitting phosphor, a blue-emitting phosphor, It is known that a red-emitting phosphor is mixed with a calcium phosphate phosphor.However, in order to match the spectral power distribution of the lamp to the spectral distribution of the reference light source, these methods require a reduction in luminous efficiency. The disadvantage is that the lamp luminous flux is greatly reduced because a relatively large amount of light emission energy in the low blue to red region is required.

On the other hand, in recent years, so-called three-wavelength fluorescent lamps that have both high luminous flux and high color rendering properties have been developed and are being put into practical use in various fields, but the phosphors used in these fluorescent lamps are Since they are all made of expensive rare earth phosphors, they have the problem of extremely high lamp costs and limited applications.

Structure of the Invention The present inventors investigated the reason for the white foamy feeling that enhances the smoothness and whiteness of the three-wavelength fluorescent lamp, and found that the smoothness and whiteness are newly adopted. It was found that the color temperature of 5000 had a significant effect. In other words, by employing inexpensive and highly efficient phosphors other than the rare earth phosphors used in long-range fluorescent lamps, we have created a fluorescent lamp that achieves the suppleness and whiteness described above. DEF 14 was conducted using a known phosphor to see if a light lamp could be realized. By the way, conventional calcium dihalophosphate phosphors have high efficiency, are inexpensive, and have a chromaticity point that can be changed significantly by changing the ratio of F to Cβ and the amount of Sb' + Mn in the composition. is publicly known. The present inventors have determined that the ratio of F to Cβ in the calcium phosphate phosphor and Sb,
M n song'z iMM2CW・5 Calcium halophosphate 7 which has the same chromaticity point as a three-wavelength fluorescent lamp
As a result of making a lamp using this lamp and conducting a visual test, it was found that the lamp had a brightness similar to that of a three-wavelength fluorescent lamp, and a whiteness that brought out the gold. V) Issued. However, the luminous flux of this lamp is more than 20% lower than that of a three-chord length emission type fluorescent lamp.
It is dark, and the illuminance is 1llif''lV when comparing the same number of lights.
It was discovered that practical application would be difficult due to the decrease in C/ζ. White color 1 that brings out the suppleness and whiteness mentioned above.
In order to increase the luminous flux of the lamp while maintaining a high KlH, it is necessary to consider the color rendering properties. The present inventors used antimony and manganese-activated calcium halophosphate as a base, added various phosphors to it, and conducted experiments on the relationship between color rendering properties and lamp luminous flux. As a result, it was found that adding a red-emitting phosphor, which is basically lacking, to the calcium halophosphate phosphor was most effective in improving color rendering.

Active magnesium heptadium germanate, europium-activated yttrium vanadate, europium-activated yttrium phosphovanadate, and europium-activated yttrium oxide used in three-wavelength fluorescent lamps are known. Of these, the lamp luminous flux is greatly reduced.''4
As a result of experiments, it was confirmed that europium-activated inolium oxide, which has the highest efficiency among the 44Φ red light-emitting phosphors, is effective in improving the color rendering property of 1- without causing any problems. However, trivalent europium-based activated yttrium oxide is used in three-wavelength fluorescent lamps as mentioned above, and the cost of the phosphor is the most expensive among positive and negative fluorophores, so it is not available in large quantities. Adding lampcos I
This is not possible because it would pull it up to the width of an f dog. In other words, the important point is how to improve efficiency and color rendering properties using a small amount of europium-activated yttrium oxide. It is proposed to increase the On the other hand, regarding calcium halophosphate phosphors, the conventional white color A) is daylight color. There is a method of making a fluorescent lamp having a color temperature of 5,000 by adding active yttrium oxide containing 1:I pium to a calcium phosphate phosphor. However, the biggest problem with this method is that unless a large amount of europium-activated yttrium oxide is cooled, a lamp of 6,000 liters cannot be obtained, which significantly increases the lamp cost. In other words, it has been found that the selection of the chromaticity point of calcium halophosphate has a great influence on the lamp luminous flux, color rendering properties, and furthermore on the lamp cost.

By the way, when the lamp color temperature is set to 5000, the chromaticity has a certain area, taking into consideration the variation in chromaticity point during mass production and the chromaticity tolerance range in which no difference is recognized in visual evaluation. When a point management range is set, it is interpreted to include everything that falls within this range. To display the chromaticity point management range, a color difference display is used, and generally MPCD by Shutt (Judd) and Matsuri Dam (Matsuriki Dam)

There are many reports that acAdam's SDCM matches well. The relationship between MPCD and SDCM largely depends on the position of the chromaticity point on the chromaticity diagram, and it is said that 1 SDcm corresponds to 2 MPCD. It is well known that macaaam's color difference display is generally expressed as a deviation ellipse in the xy-coordinate system, but since it is difficult to accurately draw the entire ellipse, it is necessary to directly fire the ellipse so that the ellipse becomes a circle. According to OMaCAdam, which uses a coordinate system converted into an oblique coordinate system, in this oblique coordinate system, the target chromaticity point tolerance range is within a circle with a radius of 5 SDCM from the center of all target chromaticity points. be.

By the way, as a result of conducting a visual sensitivity test using a fluorescent lamp having a phosphor film containing a L:I calcium phosphate phosphor as its main component and a phosphor film mixed with europium-activated yttrium oxide, it was found that it emitted light in a three-wavelength range. It has been recognized that it is necessary to have a lamp luminous flux of 96 or more with a brightness and whiteness that is not much different from that of a fluorescent lamp. Unless the luminous flux is equal to or higher than the total white luminous flux, it will not be possible to achieve the suppleness and whiteness of a three-wavelength band refracting fluorescent lamp.
(if, if the dimension is less than 1, it has been recognized that unless the average color rendering index is 8o or higher, the suppleness and whiteness of a three-wavelength fluorescent lamp cannot be obtained.) It was found that there is a close relationship between luminous flux, average color rendering index, and lamp light color that gives a sense of suppleness and whiteness, so we conducted an experiment and the results are shown in Figures 3 to 5.
Figure 3 shows the relationship between the added amount of europium-activated yttrium oxide phosphor and the average color rendering index, and Figure 4 shows the relationship between the amount of added europium-activated yttrium oxide phosphor and the Lang color temperature. 5 Figure 5 shows the relationship between the coropium-activated yttrium oxide phosphor cross-load and the lamp luminous flux. In the %O calcium phosphate phosphor, europium-activated yttrium oxide is 0%, and in the /1-unit calcium phosphate at point T, it is obtained at about 1096 and 7Jl] in the halocalcium phosphate at group 69 point U. is the third
As shown in the figure, the amount of europium-active acid Ihinotrium must be increased in the order of points S, T, and U. Furthermore, from Fig. 5, the Lang luminous flux of the calcium halophosphate phosphor with the chromaticity point S is 90% of that of white, and the luminous flux of the calcium halophosphate phosphor is 90% of that of white. If added, the luminous flux of the lamp becomes white 9096 gold. Therefore, with respect to the lamp luminous flux V, the color IW of the calcium halophosphate phosphor is
The point is to the left of point S (if it is at tIll, it will be white 909 (i

Taking all the above into account, if the chromaticity point of the calcium halophosphate phosphor is on the right side of point Sj, the color rendering conditions are satisfied, but the lamp luminous flux is white 9096i, while Ha Of
) For calcium phosphate phosphors whose chromaticity point is to the left of point U, unless 10% or more of europium-activated yttrium oxide is added, the average color rendering index does not exceed 76 gold, but the lamp luminous flux is white. 9096 k 'T, and the lamp cost would also significantly increase VC, so it was found that either station building was inappropriate.
Therefore, it was recognized that a chromaticity point between points S and U is suitable for the calcium halophosphate phosphor.
