Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent lamp device, a lighting fixture and a lighting system capable of changing a light color.

[0002]

2. Description of the Related Art Recently, there is a demand for changing the light color of lighting in accordance with the season and the preference of the user as part of making the living environment comfortable. To meet this, most primitive is to replace lamps in conventional lighting fixtures according to light color. However, this is inconvenient for replacement and cannot be expected to spread widely. Therefore, the "Toning Base Light System" was commercialized with the aim of automation. This product has a color temperature of 3,000 ° K to 1
It can be changed up to 20,000 ° K freely, and has the characteristic that it can change the light color widely. This one uses four fluorescent lamps of three primary colors of red, blue and green and four fluorescent lamps of white as a set, and each lamp is individually dimmed to diffuse light. A desired light color is exhibited by mixing and mixing light.

[0003]

However, the above-mentioned conventional lamps require fluorescent lamps of three primary colors of red, blue and green in addition to white lamps.
These are special and cannot be easily obtained anywhere compared to general lighting lamps, so there is a maintenance problem first. Also, in order to illuminate with the required brightness, a set of four lamps and a lighting and dimming device for lighting and dimming corresponding to each of these lamps are required, so the operating rate per lamp (here , Is defined as the correlation value between the average lighting time per lamp and the lighting ratio with respect to the rating.) Is low, and the price is high on the contrary. Further, since it is necessary to separately control the lamps of each color, the control method becomes complicated, and in any case, it is inevitable that it becomes expensive and complicated. Furthermore, it is necessary to satisfactorily mix the light emitted from the set of four lamps. For this purpose, a large distance is set between the diffused translucent plate and the diffuser. In addition to increasing the depth and increasing the price of the main body of the equipment, in the case of the embedded type, there is no space in the space above the ceiling, which may interfere with the arrangement of other equipment such as air conditioning.

Next, how to control each of the lighting devices 41 and 42 according to the operation of the light color switching operation switch 72 and the normal operation switch 71 will be described with reference to the example of Table 1.

[0048]

[Table 1] In Table 1, the numbers are shown as% of the rated light output of the fluorescent lamp. However, in this range, it can be said that it is almost appropriate even if it is called as% to the rated power.
In the case of dimming, the brightness is set to 60% of the total light. In the example of Table 1, in order to switch the light color in three stages and to be able to turn on all lights and dimmed lights as a normal operation, the lighting device is set to 150%, 90%, 75%, 45%.
It suffices if it can be turned on in%. In such an embodiment, the average uptime of each lamp may be 75%. This is significantly higher than the average operating rate of 25%, which is used in a set of four conventional fluorescent lamps. It should be noted that an allowable variation range of ± 10% is recognized for each of the above lighting levels.

In the case of the night light, each lighting device controls so that all the fluorescent lamps are turned off as in the case of turning off the lights. However,
In this case, a small incandescent lamp, that is, a night light provided separately from the fluorescent lamp is turned on.

When the light color is changed to the light bulb color, the first
The second lighting device 42 is deactivated, while the lighting device 41 is activated. On the contrary, when the daylight color is used, the second lighting device 42 is activated and the first lighting device 41 is deactivated. In the case of neutral white, both lighting devices 41 and 42 are operated. The light color changeover switch 72 is set to summer, spring autumn, and winter because the daylight color gives a cool color impression in the summer and the light bulb color gives a warm color impression in the winter, which is easy for the user to understand. Is. An intermediate neutral white color may be suitable for spring and autumn. Of course, it goes without saying that the user is not required to switch the light color depending on the season, but may select it according to his or her preference.

FIG. 12 is a graph for explaining changes in the light amount and the light color with respect to the lighting degree with respect to the rating of each lamp in the case of full light in the example shown in Table 1. That is, the horizontal axis represents the rated specific lighting degree, and the vertical axis represents the rated specific light amount. In the figure, 1
Reference numeral 21 indicates the light quantity of the first fluorescent lamp, and 122 indicates the light quantity of the second fluorescent lamp. As can be seen from the figure, when the first fluorescent lamp is 150% lit, the color of the bulb, the second
When the fluorescent lamps of (1) and (2) are 150%, the color becomes daylight, and when the ratio of both fluorescent lamps is 75%, the color becomes daylight. Moreover, if the total value of the light amount of both fluorescent lamps is set to 150%,
By changing the lighting ratio of each fluorescent lamp, it is possible to obtain an arbitrary light color between a light bulb color and a daylight color under a constant light amount. Of course, the same is true when the rated lighting degree is set to 0 to 200%.

In the embodiment shown in Table 1, each fluorescent lamp is lit at a high output of 150% with respect to the rated 100% lighting, but within this range, the life of the fluorescent lamp is hardly affected. Can be lit. Further, dimming is possible even with single spot lighting, which is particularly suitable for high frequency lighting. However, although the life is shortened accordingly, double spot lighting may be performed to perform higher output lighting. Therefore, in the present invention, high output lighting is generally allowed at an arbitrary level within a range of 130 to 200%, but a particularly preferable range is 150 ± 10% for the above reason. In the case of high output lighting of 200%, the average operating rate of the fluorescent lamp is 100%. Therefore, when the fluorescent lamps 41 and 42 are turned on at the same time, they may be turned on at 100%.

Next, the dimming lighting will be described. In Table 1, when both fluorescent lamps 41 and 42 are turned on at the same time, if the dimming lighting of 75% with respect to the rating is performed, all lights are in use, and one of the fluorescent lamps is 150% with respect to the rating.
It is possible to obtain almost the same amount of light as in the case of high output lighting. In a commercially available fluorescent lamp, the rated luminous flux values are slightly different depending on the color of light, but in the present invention, they can be treated as substantially equal. Also, depending on the lighting equipment used, if there is a fluorescent lamp in the off state in the vicinity, the light generated by the fluorescent lamp being lit is absorbed by the lamp, and as a result, the amount of light effectively used for illumination is slightly reduced. , I'm ignoring it here. When 90% of all lights are turned on in use, when one of the fluorescent lamps is turned on, 60% of the rated light is turned on. 60% for all light as well
When the lamp is turned on, the lamp is dimmed at 45% of the rated value. In the present invention, the dimming of all the light in use can be arbitrarily set continuously or intermittently in the range of 0 to 100%. Further, although the dimming lighting with respect to the rating is generally allowed in an arbitrary range, as is clear from the above description, when each fluorescent lamp is dimmed at 75 ± 10%,
When one of the fluorescent lamps is turned on at a high output of 150 ± 10%, the light amount becomes almost the same. In the case of a fluorescent lamp dedicated to high frequencies, two ratings, high and low, are set as the rated power, but in the present invention, the lower one is set as the rated power.

FIG. 8 is an external view of the remote control transmitter.
The remote control transmitter includes a transmitter main body 81, a normal operation section 82 arranged on the upper surface of the main body, a light color switching operation section 83, a cover 84 as a concealing means for the operation section, and an infrared light emitting section 85. There is. The normal operation unit 82 includes an all-light operation unit 821, a light-off operation unit 822, a night-light operation unit 823, and a dimming operation unit 824. The operation units 821 to 824 are related so as to interlock with the switches 711 to 714, respectively. The light color switching operation section 83 includes a summer operation section 831,
It is composed of a spring-autumn operation unit 832 and a winter operation unit 833. Operation part 8
31-833 are related so as to interlock with the switches 721-723, respectively. Further, inside the main body 81, the switches 711 to 714, 721 to 723, the transmission signal generating unit 73, the modulator 74, the infrared light emitting element 75, the power source, etc., which are opened and closed according to the operation of the operation units 82 and 83. Built in.

In this way, when the remote control transmitter is operated to obtain full light, the lighting devices 42 and 4 are used in the light bulb color and the daylight color.
No. 3 lights up at 150%, but in neutral white, each lighting device lights up at 75% at the same time, and the light amount becomes substantially the same in any case. Next, in the case of dimming, the lighting devices 42 and 43 are turned on at 90% in the light bulb color and the daylight color, but in the neutral white, the respective lighting devices are turned on at 45% at the same time. Is equivalent to.

According to the embodiment of which the configuration and operation have been described above, it is understood that the light color can be changed as desired by the operation of the light color switching operation section 83 in the remote control transmitter, for example according to the season. Moreover, since it is not necessary to frequently change the light color in daily use, it is possible to prevent an erroneous operation by concealing it with the cover 84.
