FIELD OF THE INVENTION The present invention relates to fluorescent lamps. In recent years, the depletion of energy resources has been strongly avoided, and various power-saving light sources have been published in the field of illumination light sources. In the field of fluorescent lamps, major design changes are not allowed in terms of lamp tube length, input voltage, lamp current, and lamp voltage due to compatibility with existing equipment (especially ballasts). This is done by changing the diameter, type of rare gas sealed, and pressure of the sealed gas. As an example, in order to reduce the power consumption of fluorescent lamps, for example, in fluorescent lamps filled with a mixed gas of krypton and argon, the power consumption is reduced by 5 to 8%, but the lamp luminous flux is reduced by 2 to 5%. There is a disadvantage that it decreases by %. This cannot be avoided as long as only antimony- and manganese-activated calcium halophosphate phosphors, which are currently used in large quantities, are used. One way to solve these drawbacks is to obtain a highly efficient fluorescent lamp by mixing a blue-emitting phosphor and a yellow-emitting phosphor in an appropriate ratio to synthesize white light. is proposed. According to this method, the lamp power consumption is reduced by 10% and the lamp luminous flux is almost the same as that of conventional fluorescent lamps, but the average color rendering index, which is important for qualitative evaluation of fluorescent lamps, is lower than that of conventional fluorescent lamps. 63 white fluorescent lamps,
The value drops significantly to 48-51 and cannot be used for general lighting. The present invention provides a fluorescent lamp that has high efficiency, suppresses a significant decrease in color rendering properties, and reduces lamp power consumption. The inventors have developed a fluorescent lamp that reduces lamp power consumption by approximately 5 to 8% without significantly reducing the average color rendering index, and has a lamp luminous flux that is approximately the same as a conventional white fluorescent lamp. As a result of experiments on mixed systems of various phosphors, it was found that a mixed fluorescent lamp consisting of a blue-green emitting phosphor and a yellow-emitting phosphor was superior. Among these, as the yellow luminescent material, antimony- and manganese-activated calcium halophosphate phosphor, which has traditionally been used in the largest quantity as a phosphor for fluorescent lamps, is used, and the manganese concentration of the activator and As a result of experiments to find the optimal conditions for the ratio of chlorine and fluorine among the parent constituent elements, we found that the chromaticity point when used as a fluorescent lamp was in an extremely narrow range, and was 0.425 on the CIF-xy chromaticity diagram. x0.475, 0.445y0.485
Antimony and manganese activated calcium halophosphate phosphors in the range of . Outside this range, a blue-green emitting phosphor cannot be used as a color correction phosphor to make the lamp luminous flux white, and a blue-emitting phosphor must be used.In this case, the average color rendering evaluation Number Ra is 50
The Ra value of the conventional white fluorescent lamp was found to be ~53, significantly lower than that of 63, and therefore unsuitable. Europium and manganese-activated barium magnesium aluminate phosphors (BaMg 2 Al 16 O 19 :Eu, Mn) are suitable as blue-emitting phosphors, and these phosphors emit 450 nanometer blue light based on europium emission. and a green emission of approximately 510 nanometers based on manganese emission. It was discovered through the following experiment that the luminous efficiency of this phosphor increases when it is formed on the inner surface of a glass tube having an inner diameter of a specific size. In this experiment, only such phosphors were formed on the inner surface of glass tubes with different inner diameters,
A 40W fluorescent lamp was manufactured using a conventional method, and the lamp luminous flux was measured. The results are shown in the table below.

る。[Table] From the table above, inner diameter 30mm (outer diameter 32mm) and inner diameter 36
It can be seen that fluorescent lamps using glass tubes with an inner diameter of 23 to 29 mm have significantly improved lamp luminous flux compared to fluorescent lamps using conventional glass tubes with a diameter of 23 to 29 mm (outer diameter 38 mm). . Such a result was unexpected. Examples of the present invention will be described below. 460 grams of antimony and manganese-activated yellow-emitting calcium halophosphate phosphor with chromaticity points x = 0.455, y = 0.450 and 40 grams of europium and manganese-activated barium magnesium aluminate phosphor were mixed with 1% nitrified cotton. After dispersing it in the butyl acetate solution containing it and stirring it with a high-speed stirrer,
A phosphor suspension is prepared by passing through a 300 mesh sieve. Next, pour this suspension into a tube with an inner diameter of 23 mm.
Apply the usual method to the inner surface of the glass tube 1 for 40 watts.
5.5 grams applied, dried and baked phosphor coating 2
form. Electrodes 3 and 4 are installed at both ends of the glass tube 1, and after the inside of the glass tube is evacuated, a rare gas mixture consisting of argon and krypton is introduced into the tube.
After filling an appropriate amount of 2.5Torr and mercury, we made a fluorescent lamp using the usual method and measured the luminous flux.As a result, the lamp luminous flux was 3280 lumens, and the lamp power consumption was 37
It was hot. On the other hand, the fluorescent lamps have the same configuration except for the fluorescent lamps.
The luminous flux of the fluorescent lamp using a conventional white phosphor was 3190 lumens, and the lamp power consumption was 37 watts. Therefore, the fluorescent lamp of this example has an efficiency of approximately 88.6 lumens per watt, which is a significant improvement in efficiency compared to the efficiency of a conventional fluorescent lamp using a white phosphor, which has an efficiency of 86.2 lumens per watt. It was raised. Moreover, the chromaticity point of the fluorescent lamp of this example is x=
0.377, y=0.386, it had a spectral power distribution as shown in Figure 2, and the average color rendering index was 63, which was almost the same as a conventional fluorescent lamp, and no discomfort was observed at all. Furthermore, a conventional lamp structure (100% rare gas filled with about 2 Torr of argon and a glass tube outer diameter of 32 mm) coated with a conventional white phosphor has a lamp luminous flux of 3260 lumens and lamp consumption. The electric power was 39 watts, and the lamp efficiency was 83.6 lumens per watt, and the fluorescent lamp of this example had a significant improvement in lamp efficiency compared to this. As explained above, the present invention has a chromaticity point of CIE-
0.425x0.475, 0.445y on xy chromaticity diagram
a yellow-emitting antimony- and manganese-activated calcium halophosphate phosphor in the range of 0.485;
A fluorescent lamp consisting of europium and manganese-activated barium magnesium aluminate fluorescent lamp is formed on the inner surface of a glass tube with an inner diameter within the range of 23 to 29 mm, which has high efficiency and color rendering. Therefore, it is possible to provide a fluorescent lamp which suppresses the deterioration in color rendering properties, has substantially the same color rendering properties as conventional white fluorescent lamps, and has reduced power consumption.
