2. Description of the Related Art In a living space of a house or the like, there are many requests to change the brightness of the whole room according to the atmosphere. Generally, in a residential space, high illuminance is desired when performing work that emphasizes work efficiency such as reading and writing and housework (sewing, ironing, etc.). On the other hand, low illuminance is desired for drinking or relaxing slowly. It is.

A conventional fluorescent lamp illuminator is provided with a plurality of fluorescent lamps, and the fluorescent lamps are controlled to blink or uniformly dimmed to change the indoor illuminance. There were two types of fluorescent lamps, one using a plurality of fluorescent lamps of the same type and the same output, and the other using a plurality of fluorescent lamps of the same type but having different outputs.

[0004]

Generally, in a space with high illuminance, a person with a high color temperature of light feels visually bright, and a room with a low color temperature of light does not have tightness such as blurry as a whole. It becomes a space. On the other hand, in a space with low illuminance, a high color temperature of light gives a person a dark and gloomy feeling, and a low color temperature of light results in a calm atmosphere without feeling darkness. For this reason, it is desirable for the lighting equipment in a space such as a living room of a house to have a high color temperature at high illuminance and a low color temperature at low illuminance according to the purpose.

[0005] However, in the conventional fluorescent lamp luminaire configured as described above, the illuminance can be adjusted, but the color temperature cannot be adjusted. Therefore, an illumination space suitable for the purpose can be obtained. However, depending on the illuminance level, there is a problem that the user feels insidious or blurry.

The present invention has been made in view of the above-mentioned background, and an object of the present invention is to easily obtain a lighting space according to the purpose, and to prevent the user from feeling insidious or blurry at any illuminance level. An object of the present invention is to provide a fluorescent lighting device capable of producing an atmosphere.

[0007]

In order to solve the above-mentioned problems, the present invention comprises a plurality of fluorescent lamps having different color temperatures and a changeover switch, and the changeover switch blinks the plurality of fluorescent lamps to adjust the brightness. In the fluorescent lamp lighting apparatus for performing the adjustment, when the plurality of fluorescent lamps are partially turned off from full lighting, the fluorescent lamp which is partially turned off is turned off from the fluorescent lamp on the high color temperature side among the plurality of fluorescent lamps. It is characterized by having.

[0008]

In the fluorescent lamp lighting apparatus according to the present invention, when a plurality of fluorescent lamps are partially turned off from full lighting by the changeover switch, the fluorescent lamp on the high color temperature side is turned off. When the lighting space of the color temperature is obtained, on the other hand, when all the fluorescent lamps are fully turned on, the fluorescent lamps on the high color temperature side are also turned on to have a high illuminance, and the color temperature is also shifted to a higher side to provide high illuminance and An illumination space with a color temperature can be easily obtained.

[0009]

FIG. 1 shows a first embodiment of the present invention. The fluorescent lamp illuminating device shown in FIG. 1 has two round fluorescent lamps of the same output and is used for two lamps. In the figure, the fluorescent lamp arranged at the top is the lamp 1 on the high color temperature side, and the fluorescent lamp arranged at the bottom is the lamp 2 on the low color temperature side. .

[0010] Although not shown, the fluorescent lighting equipment is
A changeover switch is provided, and the fluorescent lamp 1 on the high color temperature side and the fluorescent lamp 2 on the low color temperature side are controlled to blink by operating the changeover switch. At this time, the fluorescent lamp which is partially turned off from full lighting for brightness adjustment is the fluorescent lamp 1 on the high color temperature side among the plurality of fluorescent lamps.

With this configuration, in the fluorescent lamp lighting apparatus according to the present embodiment, when a plurality of fluorescent lamps are turned off from all on by the selector switch, the fluorescent lamps on the high color temperature side are turned off. 1 is turned off to obtain an illumination space with low illuminance and low color temperature. On the other hand, when a plurality of fluorescent lamps are fully lit, the fluorescent lamp 1 on the high color temperature side is also lit to achieve high illuminance and the color temperature is also reduced. By shifting to a higher direction, an illumination space with high illuminance and high color temperature can be easily obtained.

Therefore, when workability is emphasized,
A bright and bright lighting space with a high color temperature can be obtained in a high illuminance state, and a conservative lighting space with a low color temperature can be obtained in a low illuminance state in order to relax or relax. Is easy to set, and an atmosphere that does not make the user feel insidious or blurry at any illuminance level can be produced.

FIG. 2 shows a second embodiment of the present invention. The difference from the first embodiment is that the output of the fluorescent lamp 1 on the high color temperature side is changed to the fluorescent lamp 2 on the low color temperature side. The output is larger than that of the first embodiment, and the other configuration is the same as that of the first embodiment.

In FIG. 1, the fluorescent lamp 1 on the high color temperature side is, for example, a round fluorescent lamp of 32 w or 40 w output, whereas the fluorescent lamp 2 on the low color temperature side is, for example, a round 30 watt. The output is a fluorescent lamp.

According to such a configuration, the same effect as that of the first embodiment can be obtained, the illuminance ratio between the high illuminance level and the low illuminance level can be increased, and the color temperature of the space at full lighting can be further increased. It can also be shifted to the temperature side.

FIG. 3 shows a third embodiment of the present invention. The difference from the first embodiment is that the fluorescent lamp 1 on the high color temperature side and the fluorescent lamp 2 on the low color temperature side are different from each other. The difference is that a straight tube type fluorescent lamp is disposed inside the apparatus main body 3, and the other configuration is the same as that of the first embodiment. Even with such a configuration, the same effects as in the first embodiment can be obtained.

In the third embodiment, a single tube fluorescent lamp may be used as the plurality of fluorescent lamps instead of the straight tube fluorescent lamp.

As a fourth embodiment of the present invention, in the first, second and third embodiments, the fluorescent lamp on the low color temperature side is constituted as a bulb color fluorescent lamp or a warm white fluorescent lamp. There is. With such a configuration, the same effects as those of the first embodiment can be obtained, and at the low illuminance level, a calm atmosphere like lighting by a light bulb can be created.

In the first, second and third embodiments, when a round fluorescent lamp is used, the fluorescent lamp 1 on the high color temperature side which is partially turned off is replaced with the fluorescent lamp on the low color temperature side. Although an example in which the lamp is disposed above the lamp 2 has been described, the present invention is not limited to this, and the lamp may be disposed below the fluorescent lamp on the low color temperature side.
