Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a plurality of types of fluorescent lamps, each of which emits white light of different light colors such as light bulb color (L color) and daylight color (D color). The present invention relates to a variable light color lighting device that is switchably lit between D color lamps, etc., and in particular, a variable light color that reduces the deviation of the light color and light distribution when toning lighting is performed between the L and D colors. Type lighting device and fixture.

[0002]

2. Description of the Related Art Conventionally, as an example of an illuminating device incorporating a plurality of fluorescent lamps, there is one shown in FIGS. This lighting device 1 has a plurality of fluorescent lamps 3, 3 ... Which emit white light of a single light color arranged in a row in a horizontal direction (vertical direction in FIG. 7) in a lighting fixture 2. .

The lighting fixture 2 has a light output opening end of the fixture main body 4 closed by a shade 5 which is a translucent cover, and the plurality of fluorescent lamps 3 are arranged in a row in a row along the radial direction. They are attached to sockets 6 and 6, respectively. Note that FIG. 8 shows only one of the pair of left and right sockets 6 and omits the other, and reference numeral 7 in FIG. 8 denotes a ballast or the like of the lighting device.

By the way, there are various light colors in the white light emitted by the fluorescent lamp 3, for example, the color temperature is about 6500K.
The daylight color (D color) is a bluish white light, which is cool for summer, but has a color temperature of about 3000K.
The incandescent lamp color (L color) is white light with a reddish tint and gives a warm feeling, so it is suitable for winter.

However, the above-mentioned conventional lighting device 1
Since all the fluorescent lamps 3, 3 ... Emit a single light color, that is, white light having the same color temperature, the light color of white light is appropriately changed according to the season and the purpose of use of the illumination. There is a problem that the atmosphere in the room cannot be changed by changing it.

Therefore, in order to appropriately control the light color of the white light, for example, as shown in FIG. 9, the L-color fluorescent lamp L and the D-color fluorescent lamp D are arranged so that the light colors are alternately different. A method is conceivable in which a plurality of fluorescent lamps L and D are sequentially arranged substantially parallel to each other, and the fluorescent lamps L and D are toned and lit between the two colors L and D, that is, lit simultaneously or switched to one of the colors.

[0007]

However, in such a light color changing method, since the light colors of the fluorescent lamps Le and De at both ends thereof are different from each other as shown in FIG. 9,
When the two colors L and D are simultaneously turned on, the L color shifts to the left side in the figure, while the D color shifts to the right side, resulting in uneven light colors.

When only one of the two colors L and D is switched and lit, the center of the light distribution is shifted to the left when the L color is lit, while the light distribution is lit when the D color is lit. There is a problem that the center shifts to the right.

Therefore, the present invention has been made in view of such circumstances, and an object thereof is to control various light colors of white light and to provide a plurality of types of light sources having different light colors. An object of the present invention is to provide a light color variable illuminating device and a device that can reduce the deviation of the light color and the light distribution when the light is toned.

[0022]

Embodiments of the present invention will be described below with reference to FIGS. 1 to 6, the same or corresponding parts are designated by the same reference numerals.

FIG. 1 is a diagram showing the principle of the present invention. In the figure, a variable light color type lighting device 11 electrically connects a lighting device 13 to each fluorescent lamp 12L, 12D of a light source array 12, and Is toned.

The light source array 12 includes a plurality of fluorescent lamps 12L that emit white light of a bulb color (referred to as L color) and a fluorescent lamp 12D that emits white light of daylight color (referred to as D color).
The L color and the D color are arranged in parallel in the radial direction (horizontal direction in FIG. 1) at equal pitches so that they are alternately different.

The light source array 12 is a fluorescent lamp 12 of both colors L and D.
One of L and 12D is set to an even number (4 in FIG. 1), and the other is set to an odd number (3 in FIG. 1) to set the whole to an odd number (7 in the same figure). Fluorescent lamps 12Le of the same light color, for example L color, are arranged at both ends of the light source array 12, and the fluorescent lamps 12D located at the center O of the array are arranged.
With respect to 0, the light colors L and D are arranged so as to appear symmetrically in the figure.

On the other hand, the lighting device 13 is for lighting the plurality of fluorescent lamps 12L and 12D by toning. That is, the fluorescent lamps 12L and 12D of the respective colors are simultaneously turned on between the two colors L and D, or one of the colors L and D is switched and turned on. Therefore, the intermediate color (composite color) of the two colors L and D is emitted by lighting the two colors L and D at the same time, or the brightness of each of the colors L and D is changed.
By adjusting the light for each time, the light color of the intermediate color can be controlled more continuously.

For this reason, when all the fluorescent lamps 12L and 12D are turned on at the same time as shown in FIG. 1, the overall light color is controlled to an intermediate color that is a combination of both colors L and D. The intermediate color is the light source. It appears symmetrically with respect to the column center O, and the deviation of the light color can be reduced.

Similarly, even when one of the two light colors L, D is switched on, the respective colors L, D appear symmetrically with respect to the center O of the light source array, so that the arrangement between the respective colors L, D is different. The shift of light can be reduced.

However, these all fluorescent lamps 12L, 12
When all D are lit with the same brightness, for example, the L-color fluorescent lamp 12L is one more than the D-color fluorescent lamp 12D. Therefore, when both colors L and D are lit simultaneously, It becomes an intermediate color with a slight L color.

Therefore, the light source array 12 is provided in the lighting device 13.
Fluorescent lamps 12Le, 12Le of the same light color on both ends of the
The brightness of the fluorescent lamps 12L, 1
In order to reduce the brightness to almost half of the brightness of 2D, the fluorescent lamps 12Le and 12Le at both ends are connected with a light-reducing impedance described later.

FIG. 2 shows such a light color variable type illumination device 11.
FIG. 3 is a plan view of an embodiment in which the above is applied to the lighting fixture 14, and FIG. 3 is a sectional view taken along line III-III thereof. In these drawings, the lighting fixture 14 has the light source array 12 and the lighting device 13 built therein. ing.

The variable-light-type lighting fixture 14 has a light-transmitting cover at a light-exiting end of a fixture main body 15 in the shape of, for example, a square cylinder with a cover attached to a mounting body such as a ceiling (not shown).
It is closed by and this shade may be omitted if necessary.

The lighting fixture 14 is provided with a pair of left and right sockets 1 on the lower surface of the reflector 17 provided in the fixture body 15 in FIG.
8a and 18b are attached respectively, the pair of sockets 18a and 18b are electrically connected to the lighting device 13, and the lighting device 13 is fixed to the inner surface of the canopy portion of the fixture body 14.

The lighting device 13 is for lighting the plurality of fluorescent lamps 12L and 12D by color matching as described above.
As shown in FIG. 3, the control device 19 is connected via a signal line indicated by a broken line in the figure. The control device 19 has an operation unit for manually selecting various toning modes such as a simultaneous lighting mode, a switching mode, and a dimming mode by the lighting device 13, and as shown in FIG. 4, a power source on / off switch 19a and its relay, and an optical switch. The color changeover switch 19b and its relay, and the light receiving section 1 for receiving control signals such as infrared rays from the wireless remote controller 20.
9c. The power-on / off switch 19a supplies the required power to the lighting device 13 by its on operation and stops the power supply by its off operation. Also,
The light color changeover switch 19b is for selecting the light color of the fluorescent lamps 12L, 12D to be turned on, and is adapted to change over the changeover switches C1 to C4 for that purpose.

Further, the control device 19 receives the control signals such as the infrared light color switching signal, the dimming signal, the simultaneous lighting signal, etc. from the remote controller 20 at the light receiving portion 19c and decodes the control command of this control signal to obtain it. The change-over switches C1 to C4 are selectively controlled, or a dimming signal is given to the lighting device 13 to variously control lighting switching or dimming of the fluorescent lamps 12L and 12D.

Further, at the time of simultaneous lighting, the fluorescent lamps 12Le and 12Le at both ends of the light source array 12 are dimmed to half the brightness of the fluorescent lamps 12L and 12D other than these, and the reason is also described above. The street, L1 in Figure 4

Therefore, according to this embodiment, since the plurality of L and D fluorescent lamps 12L and 12D are symmetrically arranged, the light colors L and L when all of the fluorescent lamps 12L and 12D are simultaneously turned on. While D appears symmetrically,
The light distribution when switched on for each of the light colors L and D also appears symmetrically. Therefore, the deviation between the light colors L and D and the light distribution can be reduced.

Further, the fluorescent lamps 12Le and 12Le at both ends of the light source array 12 are replaced by fluorescent lamps 12 other than these.
Since all the fluorescent lamps 12L and 12D are dim and turned on to almost half the brightness of the L and 12D, respectively.
The light colors L and D when D is simultaneously turned on can be made substantially equal.

Further, since the toning lighting of all the fluorescent lamps 12L and 12D can be remotely controlled by the wireless remote controller 20, it is very convenient.

FIG. 5 shows a modified example of the lighting device 13 shown in FIG. 4, and since the lighting device 21 of the conventional lighting device often incorporates an even number of fluorescent lamps, the lighting device 21 is slightly different from the conventional lighting device. 1 shows an example of a case where the present invention is easily applied by improving the above.

In other words, this lighting device 21 has the same structure as the first lighting device 21A incorporated in the conventional luminaire,

%), And the fluorescent lamps 12Le and 12D at both ends thereof are connected to the above-described dimming impedances L1 and L2.

The second lighting device 21B is for lighting the fluorescent lamps newly added in order to make the number of the fluorescent lamps 12L and 12D incorporated in the luminaire 14 an odd number as a whole.

FIG. 6 shows the second and third lighting devices 21 of FIG.
A modified example in which B and 21C are integrated into a fourth lighting device 21D is shown.

In each of the above embodiments, the light colors are two colors L,
A plurality of D fluorescent lamps 12L and 12D are attached to the lighting fixture 14
Although the light color variable luminaire and the device incorporated therein have been described, the present invention is not limited to this, and the light color of white light may be N color or W color other than L color and D color, for example. Also, the number of light colors may be a combination of three or more,

[0047]

As described above, according to the first to seventh inventions of the present application, a plurality of light sources of a plurality of types having different light colors are arranged so that these light colors appear symmetrically, for example. Therefore, the light colors when these light sources are turned on at the same time appear symmetrically, and the light distributions when turned on for each light color appear almost symmetrically. That is, the deviation between the light color and the light distribution can be reduced.

Further, in the third invention of the present application, the light sources on both ends of the light source array are dimmed to approximately half the brightness of the light sources other than these and are turned on. It is possible to make the brightness of the respective light colors when they are simultaneously turned on substantially equal.
